    MODULAR FLOOR FOR PROVIDING SUPPORT TO VEHICLES AND PEOPLE ON AN UNEVEN OR SOFT SURFACE, AND SHELF, INSTALLATION METHOD, AND PRODUCTION METHOD FOR THAT
    Technical area
    A modular floor for providing support to a vehicle and / or a crowd on an uneven or soft surface of a supporting terrain has been described. The modular floor comprises at least two shelves, each shelf comprising an upper and a lower plate separated by a plurality of spacer plates. A first board comprises a male connecting element and a second board comprises a female connecting element for interconnecting the first and second boards. The connecting elements are configured to provide a modular floor of mutually locked planks both on an edge comprising a male connecting element and on an edge comprising a female connecting element. A shelf is preferably a one-piece component comprising aluminimum alloy or plastic.
    Background
    US 3,301,147 describes vehicle supporting mats and a shelf therefor. The board is an extruded element that is formed from a single piece of material, preferably 6061 aluminum alloy that has been heat treated to the T-6 condition. The shelf includes a lower supporting plate and a flat covered upper cover plate connected by webs that are placed at right angles to the two plates. The webs are placed parallel to each other so that they run co-extensively with the extrusion. The cross-section of the board thus consists of a plurality of similar section sections, with adjacent section sections sharing a web. The lower support plate and webs have a uniform and minimum thickness of 0.140 inch with filleted connection angles. The cover plate must remain flat and reinforced between the webs to ensure that it is flat and is therefore provided with a deeper cross section where increased bending loads occur.
    The shelf of U.S. Pat. No. 3,301,147 further comprises a male and female edge. The male edge comprises a modified marginal web comprising an upward opening channel on the cover plate and a downward-facing shoulder indented upwards from the lower support plate. The channel has a bottom in a plane that is separated under the cover plate, it has an inner wall that is connected to the cover plate at a rounded corner, and it has
    BE2017 / 5808 an outer wall that runs parallel to the inner wall and ends in a plane under the plate. The shoulder has a flat recess formed by an inwardly bent marginal section of the lower support plate and it is integrally connected to the marginal web. The male edge of the shelf has a male element configuration in cross section. At the opposite female edge of the shelf, the lower support plate and the flat covered upper cover plate are extended to form parts to fit with the male edge. The extension of the upper cover plate has a flanged-down flange, with rounded corners, which is adapted to hang down in the channel for angular coupling of adjacent boards. The male and female edges are further configured to have locked extension of the lower support plate of the female edge in the recess and against the shoulder of the male edge. The boards are made to fit loose and allow movement, so that it will adapt to the contours of the bearing terrain, either concave or convex.
    Figure 2 of U.S. Pat. No. 3,301,147 shows that the extruded planks may be interlocked in a zigzag configuration.
    U.S. Pat. No. 3,301,147, however, is specifically directed to aircraft landing installations, and requires a flat covered cover plate that is free of openings and / or protrusions. The shelves are therefore not provided with means to prevent slipping of vehicles and / or personnel on the flat covered cover plate. This is particularly dangerous when the cover plate gets wet due to, for example, rain. The shelves are furthermore not provided with means to prevent movement of a shelf relative to a support surface.
    In addition, the extension of the lower supporting plate on the female edge projects further out of the female edge web than the flanged downward flange of the female edge. This limits the placement of the shelves, as clearly indicated by the edge numbering (10, 11) on Figure 2 of U.S. Patent No. 3,301,147, to the placement of a male edge in the female edge of an already positioned shelf. A partially installed landing installation can therefore only be extended on the side comprising the female edges of the boards. In addition, while the extension of the lower support plate on the female edge includes a small slope on its lower surface, the slope is not long enough to allow placement of a female edge around a male edge of an already positioned shelf.
    BE2017 / 5808 U.S. Pat. No. 3,301,147 further provides no means to prevent flexing of the protruding elements on the male and female edges because of, for example, large impacts.
    U.S. Pat. No. 3,301,147 also provides no means for moving vehicles or aircraft on and / or from the landing installation.
    The present invention has for its object to solve at least some of the above problems.

    In a fourth aspect of the present invention, a method is provided for the production of a board according to the second aspect, as described in claim 15.
    The present invention is advantageous for various reasons. The oblique outer surface portion of a lower recess wall of the female connector element of a shelf is configured to place the recess of the female connector element over the hook of a male connector element of another shelf that is already positioned on a surface without being impeded. through the substrate. Alternatively, the hook of the male connecting element of a shelf can also be inserted into the recess of the female connecting element on an already positioned shelf, without being hindered by the aforementioned substrate. A road mat comprising mutually connected boards and comprising an edge comprising a male connecting element and an edge comprising a female connecting element, can therefore be extended at both edges, whereby the road mat can be extended in a faster and more flexible manner.

    A non-limiting list of uneven or soft surfaces includes a meadow, a construction site, a beach, a dune, a desert, a gravel road, a slope, and the like. Heavy equipment and / or people can at least partially sink into soft surfaces, especially after rainfall or heavy prior use. It can also be difficult to get a grip on soft and / or uneven surfaces such as wet meadows, dunes and the like. The present invention provides a covering means for providing support and for providing grip.
    A person skilled in the art will understand that the four aspects of the present invention relate to only one invention. The modular floor of the first aspect can comprise a plurality of shelves according to the second aspect, which can be mutually locked according to the third aspect and which are produced according to the fourth aspect. The modular floor preferably comprises at least two, or more preferably a plurality of, essentially identical boards according to the second aspect.
    The boards are preferably produced by extrusion. Therefore, they comprise a longitudinal and extrusion direction and a substantially uniform cross-section perpendicular to the longitudinal direction. To produce a board, an extrusion die and extrusion material are provided. The extrusion material is pushed through the extrusion die to produce the board. The extrusion material is preferably one of a metal alloy and a plastic. A non-limiting list of metals includes aluminum, brass, copper, lead, magnesium, nickel, steel, non-alloy steel, alloy steel, stainless steel, tin, titanium, and zinc. A non-limiting list of plastic includes acetal, acrylic, acrylonitrile butadiene styrene, nylon, polycarbonate, polyethylene, polypropylene, polystyrene, and polyvinyl chloride. The extrusion material is preferably one of an aluminimum alloy and a plastic, to provide optimum
    BE2017 / 5808 interaction between weight and strength. Aluminum or an aluminum alloy can be extruded hot or cold. When hot extruded, it is usually heated to 300 to 600 ° C. Extrusion is an advantage encompassed (1) it can produce extrudates comprising very complex cross-sections; (2) the extrusion material only experiences compression and shear stresses; (3) forming the parts with an excellent surface finish; and (4) in metals such as, for example, aluminum or aluminum alloy, the extrusion process can also increase the strength of the material. Because of the extrusion process, each board is a one-piece component. As an alternative to extrusion, a board can also be produced by forming a metal or plastic, for example by injection molding. For metals, injection molding is also called pressure casting.
    A cross-section of an embodiment of a board is shown in Figure 1. In addition to the longitudinal or extrusion direction, the board comprises a width direction (x) and a height direction (z). The length, width and height directions are mutually orthogonal. The shelf comprises a top side and a bottom side that are separated in the height direction (z). The shelf further comprises an upper plate (1) near the top and a lower plate (2) near the bottom. The upper and lower plates (1, 2) extend in the width direction (x) and are separated from each other by a plurality of spacer plates (3) which essentially run parallel to the height direction (z). The shelf further comprises a male connecting element (4, 5, 8, 9, 18) and a female connecting element (11, 12, 13, 16, 19) which are separated in the width direction (x) by the upper and lower plates (1). , 2) and connected to the upper and lower plates (1, 2). The male and female connecting elements are hereby connected to opposite edges of the upper and lower plates (1, 2), the opposite edges being separated in the width direction (x). The male connecting element comprises a hook connecting wall (8, 9) extending from the lower plate (2) to the upper plate (1) and a hook comprising a first hook part (5) extending outwards at least substantially in the width direction (x) from the hook connection wall (8, 9) to a corner hook part (18) and a second hook part (4) that extends at least substantially in the height direction (z) of the corner hook part (18) and upwards. The female connecting element comprises a recess (29) formed by a lower recess wall (12) extending outwards at least substantially in the width direction (x) of the lower plate (2) to a lower recess wall end, a rear recess wall ( 13) extending from the lower plate (2) to the upper plate (1), and an upper recess wall comprising a first recess part (16) extending outwards at least in
    BE2017 / 5808 substantially in the width direction (x) of the upper plate (1) to a corner recess part (19) and a second recess part (11) extending at least substantially in the height direction (z) of the corner recess part (19) and to the lower recess wall (12). The recess (29) of the female connecting element and the hook (4, 5, 18) of the male connecting element are configured for loosely interlocking adjacent planks, allowing a modular floor structure of interlocking adjacent planks to adapt on the contours of the bearing terrain, either concave or convex.
    In alternative embodiments, the modular floor may comprise a board comprising two female connecting elements that are separated in the width direction of the board and / or a board comprising two male connecting elements that are separated in the width direction of the board. In another embodiment, the modular floor can only consist of planks comprising two female or two male connecting elements. In the latter case, the shelves of the male type must be alternated with shelves of the female type. However, this requires a correct alternating stacking of the planks to properly explain the modular floor.
    In a preferred embodiment, the lower recess wall (12) comprises an outer surface (14, 15) comprising an oblique part (15) extending from a deflection line (17) to said lower recess wall end and at least partially in the height direction (z ) to the said top side. The oblique outer surface part (15) herein comprises a slope size in the width direction that is equal to at least 50% of the female connecting element in the width direction, for allowing coupling of the recess (29) over the hook of the male connecting element of a another plank that is positioned on a surface. The slope size in the width direction is equal to at least 50% of the female connecting element in the width direction, such as 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59% , 60%, 61%, 62%, 63%, 64%, 65%, 67.5%, 70%, 72.5%, 75%, 77.5%, 80%, 85%, 90%, 95 %, or any higher percentage or in between, of the size of the female connecting element in the width direction. The slope size in the width direction is preferably equal to at least 62.5% of the size of the female connecting element in the width direction.
    It is advantageous since it allows locking a new board with a modular floor comprising mutually locked boards with any one of the
    BE2017 / 5808 male and female connecting elements thereof, as discussed in the summary of the invention and below. Figures 5a to 5g show a schematic representation of a cross-section of the coupling of the recess of the female connecting element of a first board (51) over the hook of the male connecting element of a second board (50), the second board (50) is positioned on a surface (52). Figures 6a to 6e show a cross-sectional diagram of the coupling of the hook of the male connecting element of a second shelf (50) into the recess of the female connecting element of a first shelf (51), the first shelf (51) is positioned on a surface (52). Figure 5g illustrates that the first board (51) and the second board (50) are loosely interlocked, allowing for a modular floor structure of interlocking adjacent boards to adapt to the contours of the bearing terrain, either concave or convex .
    As shown in Figure 5a, the placement of the recess (29) of the first shelf (51) over the hook of the second shelf (50) includes the placement of a second recess portion (11) of the first shelf (51) behind the second hook part (4) of the second shelf (50), whereby a loose hinge-type coupling is created between the second recess part (11) of the first shelf (51) and the second hook part (4) of the second shelf (50) ), around which the first shelf (51) can be rotatably locked with the second shelf (50), as shown in Figure 5a to 5g, with the lower recess wall (12) of the first shelf (51) positioned below the first hook part (5) of the second shelf (50) while maintaining said loose hinge-type coupling.
    The applicant has found that when the oblique outer surface portion (15) does not extend sufficiently across the width of the lower recess wall (12), the lower recess wall (12) of the first board (51) substantially abrasions against and / or protrudes into the substrate (52) on which the second board (50) rests upon rotary coupling of the recess (29) of the first board (51) over the hook of the second board (50). The applicant has found that a slope size equal to at least 50% of the size of the female connecting element in the width direction is sufficient to prevent said abrasion against and / or protruding into the substrate.
    In a preferred embodiment, said oblique outer surface portion (15) of said lower recess wall (12) comprises an angle (ai) with respect to the width direction (x) of at least 5 degrees, preferably at least 7 degrees, such as 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, or any value
    BE2017 / 5808 above or in between. In addition to an inclined outer surface part (15) that extends sufficiently in the width direction (x), an increasing angle between the oblique outer surface part (15) and the width direction (x) also helps to prevent said abrasion against and / or protruding in the substrate of said lower recess wall (12). In addition, the said angle cannot become too large, since the lower recess wall must remain sufficiently strong near its lower recess wall end. The maximum angle depends on material characteristics, the thickness of the lower recess wall near the deflection line (17), and the desired strength near the lower recess wall.
    In a preferred embodiment, the upper recess wall of the female connecting element (including the first recess part (16), the corner recess part (19), and the second recess part (11)) strengthens outwards in the width direction at least up to the lower recess wall end of the female connecting element. The upper recess wall and the lower recess wall preferably extend substantially as far outwards in the width direction, wherein it comprises a common interface parallel to the height direction. When the lower recess wall extends further than the upper recess wall in the width direction, it is more likely that it will rub against and / or protrude into the substrate of the bearing terrain. It is therefore better to limit its size in the width direction in the manner described above.
    In a preferred embodiment, the male connecting wall comprises an outer surface essentially parallel to the height direction (z), and the male connecting element further comprises an upper fillet connection angle (6) and a lower fillet connection angle (7) to the attachment of the first hook part (5) with the outer surface of the hook connecting wall, wherein the corner connecting wall for each of said upper and lower filleted connecting corners (6, 7) comprises an adjacent inwardly extending thickening (8, 9). The thickenings hereby merge into a confluence part (10) of the hook connection wall comprising a thickness that is smaller than each of the maximum thicknesses in the width direction of the said thickenings of the hook connection wall.
    The male and female connecting elements are often subject to substantial tensions. The hook projects away from the hook connecting wall in the width direction. The upper and lower recess walls project away from the rear recess wall in the width direction. These walls therefore knock
    BE2017 / 5808 often against other objects during transport, for example, when a plank falls and hits the ground. In addition, when they are interlocked, they also experience substantial forces in use, for example, when a vehicle drives over a modular floor of interlocked boards. These elements must therefore have sufficient strength to prevent themselves from bending, for example at the corner hook part or corner recess part, nor at the connection to the rest of the board, for example, where the first hook part is fixed to the hook connection wall. These elements are therefore at least partially made thicker than the plank plates. Specific dimensional details of a preferred embodiment are given in the example below. The applicant has performed strength calculations, on the basis of which he has noticed that the hook connection wall can be made less thick at a height between the heights of the upper and lower filleted corners without losing significant strength. Therefore, it is possible to save on both material and shelf weight to achieve a substantially strong connection of the hook to the rest of the shelf, leading to the design described above.
    In a preferred embodiment, the upper plate (1) and the lower plate (2) comprise a plurality of ribs which extend in the longitudinal direction and are spread out with channels (20, 21). A schematic representation of a cross-section of a board comprising upper and lower boards including ribs and channels is given in Figure 2. The channels are advantageous for various reasons. They allow, for example, partial drainage of rainwater and other fluids, which would otherwise remain on the upper plate and ensure that the upper plate is smooth. In addition, the channels offer grip, both for people and for vehicles running on the top plate and for the board in relation to the ground. Projections of the surface, soles of shoes, and wheels of vehicles can at least partially enter a channel, thereby providing hook-type grip and preventing unwanted displacement perpendicular to the longitudinal direction.
    In a preferred embodiment, each rib comprises an outer rib surface and each of the upper and lower plates comprises a channel bottom wall and two channel side walls. The channel bottom wall comprises a channel bottom surface (20) that is essentially parallel to the outer rib surfaces of the two adjacent ribs. Each of said two channel side walls comprises a channel side surface (21) extending from the channel bottom surface to the outer rib surface of one of said adjacent ribs. The channel bottom surface (20), the two side surfaces (21) and an open upper surface essentially in the same plane as the outer rib surfaces of said two adjacent ribs define a
    BE2017 / 5808 channel. Each of the upper and lower plates preferably comprises a plurality of channel bottom walls and corresponding pairs of channel side walls defining a plurality of channels. The two channel side surfaces (21) of a channel herein include an angle of at least 120 degrees with the channel bottom surface (20), such as an angle of 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, and some value in between. Most preferably, each of said two channel side surfaces (21) comprises an angle of essentially 135 degrees with the channel bottom surface (20). Consequently, the said two channel side surfaces are essentially perpendicular to each other. This is advantageous since oblique channel side walls (21) relative to the channel bottom surface (20), as described above, limit the amount of dirt that can be accumulated in the corners between channel side walls and the channel bottom wall. Moreover, it also ensures that accumulated dirt can be easily removed from the channels. A washing process for removing accumulated dirt can include collecting control water in a basin including a row ramp, introducing one or more plates into the basin, washing the plates, and removing the one or more plates from the basin .
    An outer rib surface includes a rib width in the width direction. An open top of a channel comprises an upper width of the channel in the width direction. In a preferred embodiment, the upper width of the channel is equal to a maximum of 100% of the said rib width, preferably a maximum of 80% of the said rib width, most preferably a maximum of 60% of the said rib width. The applicant has found that a widened rib width relative to the upper width of the channel is advantageous to prevent slipping of persons wearing shoes with an essentially flat sole, since the contact surface with the outer rib surfaces is enlarged, whereby a larger contact area is provided where friction between a shoe sole and the outer rib surfaces is possible. Also for shoes comprising a very ribbed sole profile, the combination of sole protrusions that engage in plank channels with the enlarged contact surface between the sole and the outer rib surfaces leads to less risk of slipping.
    In a preferred embodiment, each of the upper and lower plates comprises a plurality of channel bottom walls, each spacer plate (3) of said plurality of spacer plates being connected (23) to a channel bottom wall of the upper plate and a channel bottom wall of the lower plate. Because a bottom wall is connected via sloping channel side walls to the ribs and therefore the rest of the upper or lower plate, sliding and compression forces (in the
    BE2017 / 5808 (width and / or height direction of the board) transferred to said rest at two consecutive oblique angles, thereby providing a more gradual transition of said forces and no less stress on the interconnections between a spacer plate and the upper and lower / or bottom plate.
    In a preferred embodiment, the modular floor also comprises at least one male ramp, in addition to the said boards. A schematic representation of a male ramp is shown in Figure 4. A male ramp also includes a longitudinal direction, a width direction, and a height direction that are mutually orthogonal, and a substantially uniform cross-section perpendicular to the longitudinal direction, since it is preferably produced by extrusion, and preferably in the same material as the said boards. The male ramp further comprises a lower plate (31) extending in the width direction, a ramp plate (30) comprising a non-zero angle (02) with the lower plate (31), and a male connecting element (4, 5, 8) 9, 18) connected to said bottom and ramp plates and configured to interlock said male ramp with a board of the modular floor via the female connecting element of said board. A person skilled in the art will understand that specific characteristics of preferred embodiments of the male connecting element of a board, such as, for example, the fillet connecting angles (6, 7) and the corresponding thickenings (8, 9) which merge into a narrower confluence part (10 ) of the corner connecting wall may also relate to the said male slope. A person skilled in the art will further also understand that specific characteristics of preferred embodiments of the upper and lower plates of a board, such as, for example, the ribs spread with channels (20, 21) may also relate to said male slope.
    In a preferred embodiment, the modular floor also comprises at least one female ramp, in addition to the said planks. A schematic representation of a female slope is shown in Figure 3. A female slope also includes a longitudinal direction, a width direction, and a height direction that are mutually orthogonal, and a substantially uniform cross-section perpendicular to the longitudinal direction, since it is preferably produced by extrusion, and preferably in the same material as the said boards. The female ramp further comprises a bottom plate (31) extending in the width direction, a ramp plate (30) comprising a non-zero angle (02) with the bottom plate (31), and a female connecting element (11, 12, 16 , 19, 18) connected to said bottom and ramp plates and configured to interlock said female ramp with a board of the modular floor via the male connecting element
    BE2017 / 5808 of the said shelf. A person skilled in the art will understand that specific characteristics of preferred embodiments of the female connecting element of a board, such as, for example, the characteristics related to the oblique outer surface part (15) of the lower recess wall (12) may also relate to said female slope . A person skilled in the art will further also understand that specific characteristics of preferred embodiments of the upper and lower plates of a board, such as, for example, the ribs spread with channels (20, 21) may also relate to said female slope.
    The male and female slopes are advantageous because they facilitate access to a modular floor of interlocking boards for driving on and / or the modular floor with a vehicle.
    In a preferred embodiment of the method for installing a modular floor to provide support to a vehicle and / or a crowd on an uneven or soft surface of a supporting terrain, the method comprising the following steps:
    - providing at least three essentially identical boards, each board comprising a male connecting element comprising a hook and a female connecting element comprising a recess, said hook and said recess being configured to interlock adjacent boards;
    - positioning a first board of said at least three boards on said substrate;
    - coupling the hook of the male connecting element of a second plank of said at least three planks at least partially into the recess of the female connecting element of said first plank positioned on said substrate; and
    - coupling the recess of the female connecting element of a third plank of said at least three planks at least partially over the hook of the male connecting element of said first plank positioned on said substrate.
    The method according to this preferred embodiment is advantageous since it allows a board to be mutually locked with an already positioned board on a base, with either one of the male and female connecting elements of said board. In addition, a modular floor can cope
    BE2017 / 5808 both sides can be extended at the same time, allowing a quick and flexible layout of the modular floor.
    In a preferred embodiment of the method, said at least three boards comprise a fourth board which is essentially identical to each of said at least three boards, and the method comprises at least one of the following steps:
    - coupling the hook of the male connecting element of said second board partly into the recess of the female connecting element of said first board and partly into the recess of the female connecting element of said fourth board; and
    - coupling the recess of the female connecting element of said third board partly over the hook of the male connecting element of said first board and partly over the hook of the male connecting element of said fourth board.
    The modular floor can therefore be laid in a straight configuration, as illustrated in Figure 7a, where a hook of a male connecting element essentially locks completely into the recess of a female connecting element, or alternatively in a zigzag configuration, as illustrated in Figure 7b, where a connecting element of a shelf can be partially locked with the double connecting element of each of two other shelves. The zigzag configuration is advantageous for modular floors that extend essentially essentially in the longitudinal direction (y) of the interlocked boards to provide more locking stability as well as to prevent substantial changes in height between adjacent boards in the longitudinal direction (y). To lay a modular floor in zigzag configuration comprising a fixed dimension essentially in the longitudinal direction (y) of the interlocked planks, the modular floor can comprise a plurality of planks comprising a first length in the longitudinal direction and a plurality of planks comprising a second length in the longitudinal direction, the second length being essentially equal to half the first length.
    The invention will be further described by the following non-limitative example, which further illustrates the invention, and is not intended, and should not be construed as limiting the scope of the invention.
    BE2017 / 5808
    For example
    The example relates to a modular floor comprising:
    - a plurality of boards, each board having a substantially uniform cross-section perpendicular to the longitudinal or extrusion direction (y) of the board as shown in Figure 2;
    - at least one female slope, each female slope having a substantially uniform cross section perpendicular to the longitudinal or extrusion direction (y) of the female slope as shown in Figure 3; and
    - at least one male slope, wherein each male slope has a substantially uniform cross-section perpendicular to the longitudinal or extrusion direction (y) of the male slope as shown in Figure 4.
    The plurality of planks, the at least one female ramp, and the at least one male ramp are one-piece components produced by extruding 6005A aluminum alloy that is heat-treated to the T-6 condition (aluminum alloy EN AW-6005AT6) .
    Figures 5a to 5g show a cross-section of the coupling of the recess of the female connecting element of a first board (51) of the modular system of this example over the hook of the male connecting element of a second board (50) of the modular system of this example, wherein the second board (50) is positioned on a base (52).
    Figures 6a to 6e show a cross-section of the coupling of the hook of the male connecting element of a second shelf (50) of the modular system of this example into the recess of the female connecting element of a first shelf (51) of the modular system of this example, wherein the first board (51) is positioned on a surface.
    The planks of the modular floor of this example can be interlocked in regular configuration (Figure 7a) or in zigzag configuration (Figure 7b).
    Figures 8 and 9 show a detailed cross-section of the male connection element and the female connection element of a shelf of the modular system of this example, respectively.
    A person skilled in the art will therefore understand that some features described in the detailed description of this document with respect to, and shown on, Figures 2 to 9 also relate to this example. Hereafter, dimensional details regarding the various components of the modular floor will be given.
    BE2017 / 5808 A board comprises a length (I) of approximately 3000 mm in the longitudinal or extrusion direction (y), a total width (w3) of approximately 621.8 mm in the width direction (x), and a total height (hl ) of approximately 45 mm in the height direction (z). The total height (hl) can also be smaller or larger. In certain embodiments, the shelf can have a total height (hl) of 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, or any value above or in between. The board can usually withstand bending stresses better as the total height (hl) increases. In the embodiment in this example, the total height (h1) is 45 mm. The total width (w3) consists of the width of the plank connection (w1) of approximately 600 mm between the hook connection wall and the female connection element and the length of the protrusion (w9) of approximately 21.8 mm of the hook in the width direction. The distance (w2) between two adjacent and essentially parallel spacer plates is approximately 69 mm. The thickness of the upper plate ribs (d2), channel bottom walls of the upper plate (d1), and channel side walls of the upper plate (d3) is approximately 4 mm. The thickness of the lower plate ribs (d5), channel bottom walls of the lower plate (d4), and channel side walls of the lower plate (d6) is approximately 3 mm. The thickness of the spacer plates is approximately 3 mm. The upper plate therefore comprises a thickness that is greater than the thicknesses of the spacer plates and the lower plate. The channels comprise a depth (h2, h3) in the height direction (z) of approximately 2 mm. The upper width of the channel (w4) is approximately 9 mm and the rib width (w5) is approximately 15 mm. Therefore, the top width of the channel is approximately 60% of the top width of the channel. The channel side walls comprising an angle with the corresponding channel bottom wall of about 135 degrees. Therefore, the bottom surface of the channel comprises a channel bottom width (w13) of approximately 5 mm. Because of the different thicknesses of the upper and lower plates, the inward-facing side of the channel bottom wall on the upper plate comprises a width (w6) of approximately 8.3 mm, which is larger than the width (w7) of approximately 7.5 mm from the inward facing side of the channel bottom wall on the bottom plate. The female connecting element comprises a wall thickness on the lower recess wall (h9), the rear recess wall (w18) and the upper recess wall (w6, h7) of at least about 7 mm. The thickenings of the hook connection wall comprise a width (wil) of approximately 8 mm, which is significantly more than the width (w12) of approximately 5 mm of the confluence part of the hook connection wall. The first hook part comprises a width in the height direction of approximately 12 mm. The female connecting element comprises a size of the female connecting element in the width direction (w17 + w17) of approximately 30.3 mm. The oblique size in the
    BE2017 / 5808 width direction (w20) is approximately 18.94 mm. Therefore, the oblique size is equal to approximately 62.51% of the size of the female connecting element. The oblique outer surface part comprises an angle (ai) with respect to the width direction of 9 degrees. The shelf comprises eight compartment-like sections formed by the seven spacer plates.
    The female and male slopes include a slope connection width (w22) of about 220 mm. The total width of a male ramp (w23) is approximately 241.8 mm due to the length of the protrusion (w9) of the hook of approximately 21.8 mm. The ramp plate (30) and the bottom plate (31) comprise an angle between (a2) of about 10.78 degrees. The ramp plate (30) comprises a thickness (d1, d2, d3) of approximately 4 mm, while the lower plate (31) and the spacer plates comprise a thickness (d4, d5, d6, d7) of approximately 3 mm.
    Further dimensional aspects with respect to the board and the slopes can be taken from Table 1. Parameters starting with R in Table 1 relate to the radius of curvature of the corresponding element. Parameters starting with the letter d, h or w correspond to linear sizes. A person skilled in the art will understand that a parameter in the first column of Table 1 comprises a value of approximately the corresponding size in the second column of Table 1.
