Definitions
- the invention relates to a method for stiffening plate-like material for a spatial structural member, for example a cable trough, which stiffening takes place by locally pressing through the material to form ridges.
- the object of the invention is to make the spatial structural members such that thinner material can for instance suffice, wherein the plate-like wall parts thereof will not bend or the like.
- a plate-like part of the structural member is stiffened with bending or ridges in order to obtain a profile-like plate part.
- the drawback to arranging such ridges is that the deformation of the plate material results in extra tensions in that plate-like part, whereby the structure does not remain in itself flat, but will easily deform through internal tensions.
- the invention has the object of obviating the above drawback and provides to this end a method which is characterized in that on at least one side of the ridge the thickness of the material is made locally smaller, whereby the material is made longer.
- the thickness reduction is preferably obtained according to the invention by arranging a flattened strip which runs parallel to the stiffening ridge.
- the flattened strip and the stiffening ridge can be arranged simultaneously in the material, for example by doing this continuously using rollers or the like.
- the invention also proposes to embody the flattened strip for reducing the thickness of the plate in the same order of magnitude as the length of the stiffening ridge.
- the remaining plate parts outside the zone stiffened by the stiffening ridges to a separate cold working, for example bending to standing wall parts or the like in order to form the desired spatial structural member.
- These parts do not have to comprise any stiffening elements or compensation therefor in the form of flattened strips.
- This cold deformation can be carried out either before or after the arrangement of the stiffening ridges in the plate-like material.
- the invention further relates to an apparatus for performing the method, of the invention as defined in claim 6.
- This flattening rib can be arranged on the same pair of rollers as those suitable for arranging the stiffening rib, whereby the production process can take place continuously owing to the accurate positioning of the flattened strip relative to the stiffening rib in the plate material.
- the invention further relates to a building structure form of plate material and to a building structure form in the form of a cable trough as defined in claims 8 and 9 respectively.
- the plate-like material 1 which has to be worked in fig. 1 here takes the form of a cable trough, the bottom part 2 of which extends horizontally and is carried through between two rollers 3, 4 of a pair of rollers in the direction of the arrow P1.
- two downward facing longitudinal walls 5 connect to the bottom plate 2, wherein it is noted that both bottom plate 2 and longitudinal walls 5 can be provided with a determined perforation in the form of slotted holes 6 or round holes 7.
- the free edge of the wall strips 5 can further be bent over at 8, which can take place in random manner.
- the cable trough 1 is of course depicted in reverse sense, that is, it is viewed from the underside of the bottom plate 2.
- the pair of rollers 3, 4 serves to arrange stiffening ridges 10 which run parallel to each other and which extend transversely of the longitudinal direction, that is, transversely of the direction of forward movement P1.
- the plate material is therefore pressed through locally, this such that the stiffening ridges 10 avoid bending of the bottom plate 2 in transverse direction, whereby thinner plate material can suffice and wherein greater breadths of the bottom plate 2 can be obtained.
- stiffening ridges 10 in bottom plate 2 is realized by the elevated ridges 11 on the roller 3 which co-act with recessed parts 12 in the roller 4. This is further elucidated in the cross section of fig. 2, which shows that when the rollers 3, 4 engage with each other, the elevated ridge presses through the plate 2 to form the stiffening rib 10.
- roller 3 is embodied, in addition to the rib 11, with a flattening member 13 in the form of a small elevation on the outer surface of the roller 3, which extends parallel along the elevation 11 and which serves together with the counter-surface of the roller 4 to locally reduce the thickness of plate material 2 and thus provide material for the deforming of the stiffening ridge 10.
- This thickness reduction is therefore a length compensation of the plate part 2 of the spatial structural member, whereby the above stated internal tensions can be eliminated.
- elevation 13 can also be arranged on the roller 4 instead of roller 3 or that it can still be placed on both rollers such that while the material is reduced in thickness it is not pressed through.
- the degree of thickness reduction depends of course on the height of the stiffening ridge 10 and the material requirement involved herein.
- FIG. 3 An alternative embodiment is shown in fig. 3 wherein not only are ribs and flattened compensation strips 14 arranged transversely of the longitudinal direction, parallel to the direction of forward movement P1 of the material strip, but wherein a stiffening rib 20 is also obtained in the plate material parallel to the side edges by an elevation 21 running round roller 3.
- the thus created breadth reduction of plate 1 is compensated by arranging flattened strips 22 and 23 on either side of the longitudinal stiffening ridge which are obtained by the respective elevations 24 and 25 on roller 3.
- the plate 1 according to fig. 3 is thus compensated not only in the length dimension but also in the breadth dimension.
- the advantage of this compensation is that the longitudinal strips 26 along the outside edges of the plate 1 can undergo a random cold deformation, such as for instance bending to a longitudinal wall 5 as in fig. 1, but also by arranging beaded edges and the like without internal tensions being created in the total construction.
- stiffening ridges 10 can of course take random forms, for example Z-shaped, can further enclose a different angle with the longitudinal edges, for example an angle of 45°, can be intersecting and so on, wherein it is noted that the flattened strips 14 for compensating for the length or breadth dimension can have the same form as the stiffening ridges because they extend substantially parallel thereto.
