    CLAMP
    FIELD OF THE INVENTION
    The present invention relates to a clamp suitable for mounting cement-containing strips on a framework, such as in particular for mounting fiber-cement strips or fiber-cement façade plates on a support, usually a wooden support.
    BACKGROUND OF THE INVENTION
    Cement-containing strips, in particular fiber-cement strips or fiber-cement façade panels, are now widely known for providing a low-maintenance facade for homes, offices, buildings, etc., often replacing wooden or maintenance-intensive alternatives.
    Compared with wooden alternatives, such cement-containing strips, such as fiber cement façade panels, are rigid and heavy. As such, they require special mounting systems to mount them and to keep these strips attached to walls.
    Usually a framework is attached to the supporting wall, often a framework made of metal such as aluminum or galvanized steel, but most preferably a wooden supporting structure or framework, to which framework the strips are secured.
    Mounting aids and clamps are known to provide easier mounting. The "Cedral Click" clamps shown in Figure 10 are an example of such clamps and are available from Eternit NV, Belgium. These clamps 1000 offer the possibility to mount fiber cement 1010 façade panels that have a substantially rectangular cross-section with a tapered profile on either side, with the tapered edge 1020 at the top of the façade panel on the image side of the façade panel. On the opposite underside of the façade panel, a tapered edge 1022 is provided at the rear, combined with a slot 1024 to receive a hook 1100 from the clamp 1000. The edges are shaped such that the tapered bottom edge can overlap the tapered edge on the top of the adjacent façade slab beneath it after assembly and can hide it.
    When this clamp 1000 is screwed onto the wooden frame 1200, the clamp can bend about a vertical axis, causing the two hooks 1100 and 1110 to rise from the surface of the wooden frame. The hooks are no longer aligned parallel to the fiber cement board and / or no longer fit securely into the slot 1024 and can over time cause problems with mounting and holding the façade plate 1010 hooked onto the clamps.
    Summary of the invention
    It is an object of the present invention to provide a clamp that provides greater dimensional stability during mounting on a framework, in particular a wooden framework. The clamp reduces the tendency to bend and rise from the frame surface of its hook-shaped support means.
    It is an advantage of some embodiments of the present invention that they provide a clip that avoids the aforementioned drawback of the existing clips.
    According to a first aspect of the present invention, a clamp is provided which is suitable for mounting cement-containing strips on a frame, which clamp comprises, • A plate with a front side and a substantially flat rear side, which plate comprises at least one opening for receive a confirmation means; • At least two hook-shaped support means that contact the front of the plate and stand in front of the front; The opening and the two hook-shaped carrying means defining an axis parallel to said rear side, the axis coinciding with the opening and the point on the front which is at minimal but equal distances from the hook-shaped carrying means; the plate comprising at least one elevation on the front, the elevation extending from a first point of the front on one side of the axle to a second point of the front on the other side of the axle, the plate along the elevation uninterrupted, where the increase is not a bulge.
    A bulging or "bending" is usually an elevation provided by a corresponding dent created at the rear of the plate, usually by pressing this dent into the rear of the plate.
    According to embodiments, the clamp is provided which is suitable for mounting cementitious strips on a frame, which clamp comprises: • A plate with a front side and a substantially flat rear side, which plate comprises at least one opening to receive a fastener; • At least two hook-shaped support means that contact the front of the plate and stand in front of the front; • Where the aperture and the two hook-shaped carrying means define an axis parallel to the rear, the axis coincides with the opening and the point on the front that is at minimal but equal distances from the hook-shaped carrying means; the plate comprising at least one elevation on the front, the elevation extending from a first point of the front on one side of the axle to a second point of the front on the other side of the axle, the plate along the elevation uninterrupted, which elevation is a fold, a fold or a ridge.
    By fastening means is meant any means that the clamp can mechanically fasten to an underlying support, such as a screw, nail, pop rivet and the like.
    The support or support structure can be a support of metal (for example aluminum, steel or stainless steel), or a wooden framework, usually a softwood structure or framework.
    The axis coinciding with the opening is understood to mean the axis coinciding with the center of the opening.
    The elevation extending from a first point to a second, other point actually causes an elevation to extend from a first point to a second point, these points being the extremes or extreme ends of the elevation. These points are on the front of the plate. Optionally, but not necessarily, one or both points may be at the edge of the plate. The plate can be provided from metal such as steel, aluminum alloy, copper alloy, stainless steel and the like, or from polymer such as polyamide (PA), polyester (PES), polyethylene (PE), polypropylene (PP) or acrylonitrile-butadiene-styrene (ABS) and the like.
    The thickness of the surface must be strong and rigid enough to withstand the weight of the cementitious strips or façade panels and to withstand wind loads occurring, and may depend on the type of material used to provide the clamp.
    The thickness of the clip is generally in the range of about 0.4 to about 1 mm, such as in the range of about 0.5 to about 0.8 mm, such as about 0.5 mm, about 0.55 mm approximately 0.6 mm approximately 0.65 mm approximately 0.7 mm approximately 0.75 mm.
    When a steel surface is used, the thickness of the steel surface can vary between about 0.4 to about 1 mm, such as in the range of about 0.5 to about 0.8 mm, such as about 0.5 mm, about 0.55 mm, about 0.6 mm, about 0.65 mm, about 0.7 mm and about 0.75 mm.
    Most preferably, stainless steel is used, such as stainless steel of the type A2 or A4, for example stainless steel of the type AISI 302 or AISI 304, such as AISI 304 Werkstoff No. 1.4310.
    Substantially flat back is understood to mean that this side is flat, that is, in addition to the dents that can be provided to achieve the elevations, the back of the plate has no other bulges or bulges on the back.
    The elevation or elevations provided according to the invention cause that when the fastening means are driven too deeply into the underlying support structure, for example wooden frames, the clamp has less tendency to bend about this axis, so that the two hook-shaped support means towards the front from the plate. Such rise may cause the hook-shaped support means no longer to fit correctly or correctly enough to the surface of the plate to be supported along the provided contact surface. Providing the increase or increases causes the so-called moment of inertia of the plate to increase.
    According to some embodiments of the invention, the at least one elevation may be provided by a rib having a length in the axial direction of this rib, the rib being adhered to the front of the plate, e.g. at individual points or along its entire length to the front of the plate.
    According to some embodiments, this rib is a metal or polymer rib, such as, for example, a metal or polymer wire welded or soldered to the plate. The wire can be a substantially round wire (i.e., with a circular cross section) or a wire with a profile.
    According to some embodiments, this ridge is a metal wire attached to the front of the plate. According to some embodiments, this ridge is a metal wire soldered or welded to the front of the plate.
    If the clamp is made (or produced) from a sheet of metal, then this rib can be made of the same or different metal, for example a round or profiled metal wire, and be soldered to the sheet over the length of the rib or welded.
    According to some embodiments of the invention, the plate may have a substantially rectangular shape, one pair of sides (or edges) intersecting the axis along the sides, the elevation being provided by folding the side toward the front.
    Substantially rectangular means that the edges of the rectangle can provide small notches, for example due to the manufacturing process, and that the corners of the rectangle can be rounded.
    The folded sides can be folded over an angle of preferably more than 90 °, most preferably over an angle of about 180 °, for example 180 °, or even greater than 180 °.
    The fold can be provided by folding the side through one or more consecutive individual angles. The fold may have a polygonal cross-section or a spiral-shaped cross-section, the cross-section being the cross-sectional plane with a plane perpendicular to the axis of the fold.
    According to some embodiments of the invention, at least one elevation may be a fold of the plate projecting toward the front. This pleat can have a V-shaped or U-shaped cross-section, the cross-section being the cross-sectional plane with a plane perpendicular to the axis of the fold.
    If an elevation is a fold or a fold, the first and the second point are usually on the side or edge of the plate.
    Optionally, the clamp comprises a plate with additional elevations on its front side. These elevations can be provided to press the contact surface of the cementitious strips to be secured with the clamp onto the hook-like support means. Such elevations, which are ridges, folds, folds, or bulges, are usually provided in a direction parallel to the mounting direction of the plate in the clamp and substantially parallel to the axis that coincides with the opening and the point on the front which is minimal. but equal distances from the hook-shaped carrying means.
    A bulging or "bending" is usually provided by a corresponding dent created at the rear of the plate.
    Optionally, this additional elevation or elevations together with the elevation extending from a first point of the front on one side of the axle to a second point of the front on the other side of the axle can form one integral elevation.
    Providing such additional elevations can create a recess into which the fastening means or fastening means (such as a screw or rivet) can be sunk.
    According to some embodiments of the invention, the elevation may be U or V shaped, the lower section of the U or V shape intersecting the axis.
    According to some embodiments of the invention, the at least one elevation can be provided between the opening and the point on the front that is at minimal but equal distances from the hook-shaped support means.
    According to some embodiments of the invention, the opening can be placed between the at least one elevation and the point on the front that is at minimal but equal distances from the hook-shaped support means.
    According to some embodiments of the invention, at least a second elevation may be provided on the front, the elevation extending from a first point of the front on one side of the axle to a second point of the front on the other side of the axle wherein the plate is continuous along this second elevation.
    According to some embodiments, the second elevation is provided between the opening and the point on the front that sits at minimal but equal distances from the hook-shaped support means.
    According to some embodiments, the gap is between the second elevation and the point on the front that is at minimal but equal distances from the hook-shaped support means.
    Preferably, the first and the second elevation are provided on opposite sides of the opening.
    The circumference of the clamp plate may have any shape, but is generally polygonal, usually rectangular, square, elliptical or even round in shape. The corners of the polygonal shape can be rounded.
    According to some embodiments of the invention, the hook-shaped support means can form an integral part with the plate, the hook-shaped support means being bent out of the plate.
    The hook-shaped support means can be provided by making a U-shaped or V-shaped slot in the plate and the lip thus provided through a first angle up to about 150 ° (and usually about 90 °) around the connection between the lip and the plate bending, that is, towards the front of the plate, and once again bending the bent lip about an axis substantially parallel to the connection between the lip and the plate through a second angle, so that a part of the outer part of the lip viewed from the front of the plate is parallel or slightly inclined.
    In addition to the two hook-shaped carrying means, additional, similar or different hook-shaped carrying means can be optimally provided.
    According to embodiments of the present invention, the clamp comprises three hook-shaped support means, all of which are provided by making a U-shaped slot in the plate and the lips thus provided through an angle of about 90 ° upwards, i.e., towards the front of the plate, to bend the connection between the lip and the plate and again to bend the bent lip about an axis substantially parallel to the connection between the lip and the plate through yet another second angle of about 90 °, so that a part of the outer part of the lip from the front of the plate is substantially parallel. The plate of the clamp has a substantially rectangular circumference, two of the hook-shaped support means are provided with their concavity facing one of the long sides of the rectangular shape, the third hook-shaped support means is provided with its concavity directed towards the other of the long sides of the rectangular shape. The connections between the lip and the plate are all substantially coaxial.
    These bending actions can take place in one bending process step or in different steps. Cutting the U or V-shaped slots can be done by punching or cutting, such as laser cutting or sawing with suitable saw blades.
    The plate of the clip may further comprise additional openings to receive additional fasteners.
    According to some embodiments of the invention, the at least one elevation may have a thickness of about 0.5 to about 2 mm.
    The thickness of the elevation is to be understood to mean the maximum distance in a direction perpendicular to the front of the plate between the front of the plate adjacent to the elevation and the points along the surface of the elevation.
    More preferably, the at least one elevation may have a thickness of about 0.6 to about 1.8 mm, even a thickness in the range of about 0.7 to about 1.6 mm, such as about 0.8 mm, about 0.9 mm, approximately 1.0 mm, approximately 1.1 mm, approximately 1.2 mm, approximately 1.3 mm, approximately 1.4 mm, approximately 1.5 mm, approximately 1.6 mm or approximately 1.7 mm.
    The hook-shaped support means can have a distance between the bearing part, in particular the upright bearing part, of the hook-shaped support means and the plate from approximately 2 mm to approximately 10 mm, such as between approximately 3 mm and approximately 8 mm, for example approximately 5.5 mm or about 6.9 mm.
    The height of the upright part of the hook-shaped support means can vary between approximately 2 mm and approximately 8 mm, such as between approximately 3 and approximately 7 mm, for example approximately 3 mm, approximately 3.1 mm, approximately 3.2 mm, approximately 3, 3 mm, about 6.2 mm, about 6.3 mm, about 6.4 mm, about 6.5 mm, about 6.6 mm or about 6.7 mm.
    The width of the upright portion of the hook-shaped support means can vary between about 4 mm and about 20 mm, such as between about 5 and about 18 mm, e.g. about 6 mm, about 7 mm, about 8 mm, about 9 mm, about 10 mm approximately 11 mm approximately 12 mm approximately 13 mm approximately 14 mm approximately 15 mm approximately 16 mm or approximately 17 mm.
    The openings are generally but not necessarily circular and may have a diameter in the range of about 2 to about 8 mm, usually in the range of about 3 to about 7 mm, such as about 3.5 mm, about 4 mm, about 4, 2 mm, approximately 4.5 mm or approximately 5 mm.
    The plate may preferably have a substantially square or rectangular shape, with sides having a length of about 20 to about 110 mm, such as a long side of about 30 to about 100 mm, usually between about 50 and about 80 mm, e.g. 55 mm, approximately 60 mm, approximately 65 mm or approximately 70 mm. The short side can vary between about 20 and about 50 mm, such as between about 30 mm and about 40 mm, e.g. about 31 mm, about 32 mm, about 33 mm, about 34 mm, about 35 mm, about 36 mm, about 37 mm, approximately 38 mm or approximately 39 mm.
    The first and the second point between which the elevation extends or lies are preferably at a distance of about 18 to about 95 mm from each other, usually between about 25 and about 85 mm, such as between about 43 and about 70 mm, e.g. about 47, about 48, about 49, about 50, about 51, about 52 or about 53 mm.
    The elevation is generally substantially straight or linear, or slightly curved.
    The clamps according to the first aspect of the invention can be used to mount cementitious strips, such as fiber cement strips, on support systems, usually frames of aluminum, steel or wood.
    Fiber cement strips or products are well known in the art. The fiber cement strips are made from fiber cement slurry, which is formed into a so-called "green" (untreated) fiber cement product and then cured.
    Depending to a certain extent on the hardening process used, the fiber cement slurry generally comprises water, process or reinforcement fibers comprising both natural organic fibers (generally cellulose fibers) and synthetic organic fibers (polyvinyl alcohol, polyacrilitrile, polypropylene, polyamide, polyester, polycarbonate, polyethylene, etc.) can be cement, for example Portland cement, limestone, chalk, quick lime, slaked or hydrated lime, crushed sand, silica sand flour, quartz flour, amorphous silica, condensed silica smoke, microsilica, metakaolin, wollastonite, mica, perlite, vermiculite, aluminum hydroxide, pigment, antifoaming agents , flocculants and other additives. Optionally, a color additive (e.g., pigment substances) is added to obtain a fiber cement product that is called colored in the mass.
    The "green" fiber cement board is cured, usually by hardening in air (air-cured fiber cement products) or under pressure in the presence of steam and at elevated temperature (autoclaved). For autoclaved products, sand is usually added to the fiber cement slurry. The autoclave hardening usually results in the presence of Tobermorite of 11.3 Â (Ängstrom) in the fiber cement board.
    Fiber cement strips, also called fiber cement plates or fiber cement panels, are usually made using the known Hatschek process, the "flow-on" process or the Magnani process.
    The fiber cement board can be obtained by first providing a "green" fiber cement board which is compressed before curing, i.e., air curing or autoclave curing.
    The "green" fiber cement board, after being made with the Hatschek process, can first be pre-cured in air, after which the pre-cured plate is further cured in air until it has its final strength, or is autoclaved using pressure and steam to give the plate its final properties.
    Typical properties are plate thicknesses, which can vary from 4-20 mm, such as 7.0-13.0 mm. The density of the strips can vary from 0.5-2.2 kg / dm3, such as 0.6-2.0 kg / dm3. In addition to thickness, the dimensions of the plate can vary from approximately 1 meter to approximately 1.7 meters wide and 1-3.6 meters long. When the fiber cement strips are used as facade panels, the strips are generally rectangular, optionally provided with recesses to receive the support means, or a tongue and groove means, the rectangle having a short side in the 150600 mm area and the long side can be up to 4 m. Typical dimensions are 150-400 mm at 3.6 m or less, such as 150-190 mm at 3.6 m or less.
    The clamps according to the invention are particularly useful for mounting facade panels, such as fiber cement facade panels. Such facade panels of fiber cement can generally be autoclaved fiber cement strips, optionally provided with recesses, tapered edges, slots and the like to facilitate mounting by means of the clamps. The façade panels can be provided with a decoration, usually a profiled decoration from the image side, which imitates a wood structure. This decoration can be provided by grinding and milling after the fiber cement has hardened, or by profiling the "green" plate, for example when a Hatschek process is used, using a collecting drum with a surface that reflects the wood imitation image or by using it. making a press to compact the "green" plate, which press has a surface that reflects the wood imitation image.
    The present clamp is particularly useful for mounting façade panels, such as potted cover and "clapboard" constructions, and thus for mounting façade panels with a strip-like shape with a long and a short side.
    According to a further aspect of the present invention, a method is provided for mounting a cementitious strip on a framework, the method comprising the steps of • Providing a framework; Providing at least one clamp according to the first aspect of the invention; • Mount the clamps on the carrier; • Bringing the cement-containing strip into contact with the hook-shaped support means, whereby the cement-containing strip is transferred to the frame.
    The framework is usually a steel, an aluminum or a wooden support structure.
    The cement-containing strip can be a facade plate. The cement-containing strip is preferably a fiber-cement board, for example facade plate.
    The façade panel and the clamp can be formed in such a way that the clamps are invisible when mounting the façade panel on the frame, viewed from the side opposite the side where the front of the clamp and the façade panel make contact.
    The clamps according to the invention can provide the option of mounting fiber cement façade panels that have a substantially rectangular cross section with a tapered profile on both sides, the tapered edge on the top of the façade panel being on the image side of façade panel. A tapered edge is provided at the rear on the opposite underside of the facade plate, combined with a slot for receiving the hook-shaped support means from the clamp. The edges are shaped such that the tapered lower edge can overlap the tapered edge on the top of the adjacent, facing façade plate after assembly and hide it from view.
    The façade panel, such as the Cedral Click façade panels from Eternit NV, Belgium, is autoclave-hardened fiber cement strips that have an image side with a wood-like appearance and a density of approximately 1300 kg / m3. Facade panels usually have a density in the range of 1100-1700 kg / m3.
    According to a further aspect of the present invention, a clamp according to the first aspect of the present invention is used to mount cementitious strips on a frame.

In this regard, it will be apparent to those skilled in the art that various modifications and variations of the present invention can be made without departing from the scope or spirit of the invention. For example, features that are illustrated or described as part of one embodiment may be used in another embodiment and thus yield a further embodiment. It is therefore intended that the present invention cover such modifications and variations as fall within the scope of the appended claims and their equivalents.
    In the first figure, a clamp 100 according to the invention is shown in side, top and front view.
    This clamp comprises a metal plate 11 (from AISI 304 stainless steel, Werkstoff No. 1,410) with a front side 13 and a substantially flat rear side 15. There are two openings 17 and 18 for receiving a fastener, which is usually a screw when the clamp is used to mount façade panels or strips on a wooden framework. This fastener can be a pop rivet when a steel framework such as stainless steel or aluminum is provided.
    This clamp comprises two hook-shaped carrying means 21 and 23 which contact the front side of the plate and stand in front of the front side. These two hook-shaped support means are provided by cutting out a U-shaped slot and bending the lip 211 through an angle of 90 ° towards the front and bending the lip again 90 ° so that there is a small piece of plate 213 that is parallel at the front.
    The opening and these two hook-shaped support means define an axis 30 parallel to the rear, which axis coincides with the opening and the point 32 on the front, which point 32 is at a minimum distance from the hook-shaped support means at equal distances.
    The plate comprises at least one elevation 40 on the front, which elevation extends from a first point 42 of the front, which point 42 is on one side of the axis, to a second point 44 of the front, which point 44 on the other side of the axle. The plate remains uninterrupted along the elevation 40.
    The thickness T1 of the plate is 0.6 mm; it has a width W of 60 mm and a height H of 37 mm.
    The increase is achieved by providing a selectively profiled wire 45 on the front of the plate. This wire is a metal wire and is soldered or welded to the plate. The wire as such provides a corresponding increase in height T2 and width Wr in the range of about 1.4 mm to about 3 mm.
    The aperture 17, which has a diameter of 4.2 mm and is arranged centrally along the width W, sits between the elevation 40 and the two hook-shaped support means. The second identical opening 18 is coaxial with point 32 and first opening 17.
    The clamp can carry strips 200 with a thickness D of about 5.5 mm in its hook-shaped support means if the lips of the hook-shaped support means can be visible on the visible side of the plate, for example a facade plate made of fiber cement. The thickness D1 is defined by the dimensions of the elevation 40 and the hook-shaped support means 21 and 23.
    In an alternative application, as shown in Figure 2, this clamp 100 is used to mount facade panels in a non-visible manner; the plate 201 on its side contacting the clamp has a thinning 203 along a zone, and a notched slot 205 to receive the lip of the hook-shaped support means 21. Examples of such façade panels are "Cedral Click" façade panels from Eternit NV, Belgium.
    Figure 3 shows an alternative clamp 110 in front and side view, with the same references referring to the same features. The dimensions and the materials used are identical to those at terminal 100.
    The elevation is between the opening 17 and the two hook-shaped carrying means.
    As Figure 4 shows, this clamp 110 can be used to mount a plate 200 and 201 with visible or non-visible mounting on its top and bottom. The strips 200 or 201 must be placed in the clamps after they have been screwed or attached to the support.
    For invisible mounting, a clamp 120 as shown in Figure 5 is more convenient. At terminal 120, the same references refer to the same features. The dimensions and materials used are identical to those at terminal 100. The terminal further comprises a third hook-shaped support means 25 whose concave side or opening faces the side 50 of the rectangular shape of the clamp 120, while the opening or concave side of the means 21 and 23 are directed to the opposite side 52 of the shape of the clamp. The lips of the three hook-shaped support means are connected to the plate 11, these connections being aligned along an axis 60.
    The clamp has two additional elevations, here bulging, on its front side 13, namely bulging 70 and 72. They extend in a direction parallel to the axis 30. As Figure 6 shows, this clamp 120 facilitates the mounting of strips 201 , such as fiber cement façade panels, using non-visible mounting. These additional elevations may also be provided using an identical or similar metal wire as used for the elevation 40.
    Figure 7 shows yet another clamp 130, which clamp is useful for non-visible mounting of facade panels. At terminal 130, the same references refer to the same features. The dimensions and materials used are identical to those at terminal 120.
    The clamp 130 has one elevation, being a wire 45 on its front side 13, which is U-shaped. The U-shape legs 81 and 82 extend parallel to the axis 30. The U-shaped middle section 83 of the elevation crosses the shaft 30. The aperture 17 is located between the elevation where it crosses the shaft 30 and the two hook-shaped support means 21 and 23.
    Figure 8 shows yet another clamp 140. At terminal 140, the same references refer to the same features as with the other aforementioned terminals. The elevation 40 is created by making a fold 71 in the plate and allowing the fold to protrude to the front of the plate.
    Figure 9 shows a further clamp 150 according to the invention, wherein the same references refer to the same features. This clip 150 has two elevations 40 and 41, which are provided as folds 91 and 92. The first elevation 40 is provided by folding the edge of the plate on side 52 over three separate, consecutive angles of about 90 ° towards the front. As such, a fold 91 with a polygonal cross-section is obtained. The second elevation 41 is provided by rolling the edge of the plate on side 50 towards the front. As such, a fold 92 with a spiral cross-section is obtained.
    Needless to say, the two elevations can be provided by using folding or rolling techniques, thus providing similar or identical elevations.
    It is to be understood that although preferred embodiments and / or materials have been discussed to provide embodiments of the present invention, various modifications or changes can be made without departing from the scope and spirit of this invention.
