    Scaffolding with rib structure
    BACKGROUND OF THE INVENTION
    The present invention relates to a scaffolding with a rib structure.
    Scaffolding includes a plurality of vertical posts that are interconnected with horizontal cross members, horizontal struts and diagonal struts to form a rigid unit. The scaffolding can be provided with a grating structure on one of the vertical main sides, for example to place decorative items, wooden or metal panels or plates, plates, advertisements or banners on the scaffolding at a festival or construction site. Due to the temporary use, the grid structure is built rather provisionally, using wooden slats that are attached to the uprights and cross beams by plastic cable ties or other disposable items. When the scaffolding is dismantled, the wooden slats and the plastic cable ties are thrown away since they can no longer be reused.
    It is an object of the present invention to provide a scaffold with a reliable grid structure whose parts can be reused.
    SUMMARY OF THE INVENTION
    According to a first aspect, the invention provides a scaffold comprising a plurality of vertical posts interconnected with horizontal cross members, horizontal struts and diagonal struts to form a rigid unit, and at least one grid structure on a vertical main side or front of the scaffolding wherein the grid structure comprises a grid with elongated horizontal ribs and elongated vertical ribs in the same vertical plane attached to the uprights with grid couplings, the grid couplings comprising a group of four rings with passages receiving portions of the ribs and completely enclosing the form intersections of the grid.
    The scaffolding according to the invention comprises specific grid couplings attached to the posts to form the crossings and thereby the solid base for the grid. The same grid connections can be used multiple times in different grid configurations.
    In one embodiment, the horizontal ribs and the vertical ribs have their ends within the grid couplings, wherein the grid can be configured on site by providing ribs and grid couplings at the main side areas where the grid is needed.
    In one embodiment thereof, two opposite ends of either the horizontal ribs or the vertical ribs within the lattice couplings are in abutment with each other, and the ends of the other two of the horizontal ribs or the vertical ribs are in abutment with the sides of the adjacent ribs. . In this configuration, the two adjacent ribs of two consecutive grid couplings automatically enclose the rib extending therebetween, so that the grid can be built up by attaching only grid couplings to the uprights and inserting ribs into the grid couplings.
    In one embodiment, the horizontal ribs and the vertical ribs are elongated wooden slats with a rectangular cross section. Such slats can be purchased at any local store, with only a superfluous amount of grid couplings having to be present in advance at the construction site.
    In one embodiment, the rings are provided with one or more fixing openings, preferably a series of fixing openings, and a screw that is screwed into the received rib via one of the one or more fixing openings. As far as the screws are needed, they can easily be reused.
    In one embodiment thereof, the grid comprises a plurality of parallel horizontal ribs and a plurality of parallel vertical ribs that form a plurality of rows and columns, the screws being applied to the grid couplings on the outer border of the grid while the inner grid couplings are substantially free of such screws. The inner grid couplings are completely filled with ribs, so that the received ribs automatically remain in position without the use of screws.
    In one embodiment, the grid couplings are made of steel.
    In one embodiment, the grid couplings each comprise a rotary bearing between the group of rings and the post to which they are attached. The rotation bearing allows the ribs to extend locally obliquely with respect to the uprights or the cross members.
    In one embodiment, the posts each comprise a tube and a plurality of rosettes around the tube that are provided with mounting openings around and adjacent to the outer circumference of the rosette, the grid couplings each comprising a wedge head with two jaws which together define a jaw in which a portion of the rosette, the jaws including a slot through which the wedge extends, which passes through the attachment opening of the confined portion of the rosette. This type of uprights are very suitable to be assembled and disassembled in a short period of time, leaving enough time to configure the grid structure.
    In one embodiment thereof, the rosettes have repetitive identical spacings along the uprights, the lengths of the vertical ribs being an integer multiple of the spacing between successive rosettes. In this way the ends of the ribs always end at a grid connection, making it easy to mount the grid. The integer plural is, for example, one, two, three, etc.
    In one embodiment, the uprights have repetitive identical spacings in the horizontal direction, the lengths of the horizontal ribs being an integer multiple of the spacings between successive uprights minus one time the width of a vertical rib. In this way the ends of ribs always end at a grid connection, making it easier to assemble the grid. The integer plural is, for example, one, two, three, etc.
    According to a second aspect, the invention provides a method for building a scaffold, wherein the scaffold comprises a plurality of vertical posts interconnected by horizontal cross members, horizontal struts and diagonal struts to form a rigid unit, and at least one grid structure on a vertical main side or front of the scaffold, the grid structure comprising a grid with elongated horizontal ribs and elongated vertical ribs in the same vertical plane that are attached to the uprights with grid connections, the grid connections comprising a group of four rings with passages sharing received from the ribs and completely encased to form the crossings of the lattice, the method comprising interconnecting the posts and the cross members, attaching the lattice couplings to the posts, and inserting the ribs into the passages of the rings.
    In one embodiment thereof, the horizontal ribs and the vertical ribs have their ends within the lattice couplings, two opposite ends of either the horizontal ribs or the vertical ribs within the lattice couplings being in contact with each other and the ends of the other two of the horizontal ribs or the vertical ribs are in abutment with the sides of the adjacent ribs, the method comprising inserting the ends of either the horizontal ribs or the vertical ribs into two opposite rings with the ends spaced apart, and subsequently inserting the ends of the other two of the horizontal ribs or the vertical ribs to come into abutment with each other, the spaced ends coming into abutment with the sides of the abutting ends.
    The aspects and measures described in this description and claims of the application and / or shown in the drawings of this application can, where possible, also be applied separately from each other. Those individual aspects, and other aspects, can be the subject of split-off patent applications directed to them.
    BRIEF DESCRIPTION OF THE DRAWINGS
    The invention will be elucidated on the basis of an exemplary embodiment shown in the accompanying drawings, in which:
    Figure 1 is an isometric view of a scaffolding to which a rib structure is attached by means of grid couplings according to an embodiment of the invention;
    Figures 2A-2C are details of Figure 1 at one of the grid couplings; and
    Figures 3 and 4 are isometric views of one of the grid couplings of Figure 1.
    DETAILED DESCRIPTION OF THE DRAWINGS
    Figure 1 shows a scaffolding 1 comprising a plurality of vertical uprights 10 connected to each other with horizontal support beams 20 to form the vertical major sides of the scaffolding 1. The uprights 10 are connected to each other by means of horizontal braces 30 and diagonal braces 40.
    The vertical uprights 10 each comprise a steel tube 11 and a plurality of circular rosettes 12 around the tube 11. The rosettes 12 are provided with mounting openings 13 around and adjacent to the outer circumference. The vertical uprights 10 are supported by steel legs 15. The horizontal cross beams 20, the horizontal struts 30 and the diagonal struts 40 all comprise a steel tube 21 and two steel coupling 22 at the ends of the steel pipe 21. The steel couplings 22 are known per se, and include a wedge head with two jaws confining a portion of the rosette 12 to engage the steel tube 21, and a wedge extending through the jaws and through one of the mounting openings 13 to engage the coupling fix the engaged rosette 12.
    The equal intermediate distances A between the rosettes 12 of the uprights 10 are 500 millimeters. The equal intermediate distances B between the center lines of the successive horizontal cross members 20 is 2000 millimeters. The equal intermediate distances C between the center lines of successive vertical uprights 10 is 2072 millimeters.
    The scaffolding 1 comprises a rib structure 50 which is attached to the uprights 10 on one of the main sides of the scaffolding 1 by means of identical steel lattice couplings or rib couplings 60 according to an embodiment of the invention. The rib structure 50 comprises vertical ribs 51 and horizontal ribs 53. These ribs 51, 53 are wooden slats which together define a wooden grid to which wooden slats 56 are attached in this example. One of the rib couplings 60 is shown in more detail in Figures 3 and 4. The rib couplings 60 comprise an octagonal base plate 61 and four U-shaped brackets 62 with a straight rear strip 63 and two parallel legs 64, the ends of which are welded to the base plate 61 . The brackets 62 are mutually positioned crosswise with the coming legs 64 welded together. The brackets 62 define together with the back plate 61 a group of four mutually fixed rectangular rings with four passages 65 around the ends of the ribs 51, 53 to completely circumvent, enclose, enclose or limit their circumference. The back strip 63 is provided with a series of in this case three fixation holes 66.
    As shown in Figures 2C and 3, the rib couplings 60 are provided on the opposite side of the base plate 61 with a wedge head 70 with an upper jaw 71 and a lower jaw 72 which together define a mouth 73 in which a portion of the rosette 12 is enclosed to which it are linked. The jaws 71, 72 each include a curved end face 74 that engages the steel tube 21, and a slot 75 through which a wedge 76 extends through the attachment opening 13 of the enclosed rosette 12. The wedge 76 ends with a wider cam 77 that can pass through the slots 75 except at a narrower edge thereof in the upper jaw 71, whereby the wedge 76 can be fully withdrawn from the mouth 73 without detaching from the upper jaw 71. wedge 76 downwards in direction E by inserting the mounting openings 13 of the rosette 12, the rib couplings 60 are fixed to the vertical uprights 10 without play. In this embodiment, the wedge head 70 is integral with the base plate 61 and the four rings with the passages 65. Alternatively, the rib couplings 60 include a rotation bearing between the wedge head 70 and the base plate 61 to support a diagonal orientation of the ribs 51, 53.
    The rib structure 50 is constructed by connecting the rib couplings 60 to the scaffolding 1 at the intended intersections of the ribs 51, 53. The ribs 51, 53 have a length of 2000 millimeters, a width of 69 millimeters and a thickness of 44 millimeters, which is a standard size for wooden slats. First, the opposite ends 54 of the horizontal ribs 53 are inserted in direction F into the horizontal passages 65 of the rib couplings 60. Secondly, the opposite ends 52 of the vertical ribs 51 are inserted in direction F into the vertical passages 65 of the rib couplings 60. The coming ends 52 of the vertical ribs 51 abut each other within the rib couplings 60, while the ends 54 of the horizontal ribs 53 within the rib couplings 60 abut the sides of the vertical ribs 51.
    Since the vertical intermediate distances B between the couplings 60 are 2000 millimeters, the abutments of the coming sides 52 of the vertical ribs 51 within the rib couplings 60 are repeated vertically. Since the intermediate distances C between the center lines of successive vertical uprights 10 are 2072 millimeters, there are intermediate distances between the lateral surfaces of the adjacent ends 52 which are repeatedly equal to the intermediate distances C minus twice the width of the vertical ribs 51, which intermediate distances in this example 2003 are millimeters. The horizontal ribs 53 are thus repeatedly enclosed in the horizontal direction between the vertical ribs 51 with a clearance of approximately 3 millimeters. Only in the rib couplings 60 that do not receive four ends 52, 54 should the ends 52, 54 be fixed by screwing through one of the fixing openings 66. These rib couplings 60 are located on the outer edge of the rib structure 50. Since the fixing holes 66 to form a row, the inserted ribs 51, 53 practically always have some unspoiled wood behind one of the fixing holes 66 to receive a screw.
    Except for the crossings on the outer edge of the rib structure 50, the rib structure 50 can be mounted and attached to the scaffolding 1 by means of the rib couplings 60 without the need for any further disposable fastener. The same wooden slats with the standard length can be used multiple times. The screws can be screwed into the portion of the ends of the recycled ribs 51, 53 that are not worn by prior compositions.
    The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be evident to those skilled in the art that fall within the scope of the present invention.
