Definitions
- the invention relates to a working platform for scaffolding or the like, which can be fastened to two horizontal cross bars of the scaffolding, consisting of at least one rectangular support frame composed of longitudinal and cross members, the end faces formed by the cross members each having an adjacent end face on the other Scaffolding provided at the same height in parallel, and from a running surface held on the supporting frame, preferably in the form of a perforated plate.
- the respective support frame is equipped with a plate-shaped covering, which generally consists of a glued plywood and is riveted to the support frame.
- a plate-shaped covering which generally consists of a glued plywood and is riveted to the support frame.
- the high reveal during use of the work platform leads to the enlargement of the rivet holes in the plywood over time, so that the covering cannot make any contribution to the rigidity of the work platform and is not taken into account in its structural calculation.
- the increasing, if only slight, displaceability of the covering on the supporting frame also contributes to a reduction in the surefootedness when using the work platform. It has therefore already been proposed that the plywood panels are surrounded by a circumferential metal support frame resting on the straps of the support frame, especially if the covering is riveted to its support frame by means of connecting elements with the support frame.
- the holding frame is less threatened by permanent deformation in the bores for the connecting elements than the plywood panels, so that wear-related loosening in the area of these connecting elements can actually be avoided even when the working platform is subjected to high loads.
- Such a work platform is, however, expensive.
- At least the longitudinal beams consist of a preferably extruded hollow profile which is approximately rectangular in cross section, each of which has two parallel vertical webs and horizontal belts is composed.
- a box-shaped design of the side members leads to a torsion-free design of the support frame, in particular if the webs of the cross members are respectively carried out to the outer web of the side members at their corner nodes and welded to the belts and / or webs of the side members.
- a corner knot is very robust and highly resilient;
- such a construction has the advantage that the end faces of the support frame, like the long sides thereof, each form closed surfaces.
- the object of the invention is to make a work platform of the type specified in the introduction more reliable with simple means and, moreover, to design it in such a way that the running surface improves the rigidity of the work platform in the long term and in the static calculation can be included; moreover, it should be easy to manufacture and easily connectable to the supporting frame. At the same time, care should be taken to ensure that the accumulation of dirt and rubble on the work platform is prevented. Furthermore, the arrangement should be such that several working platforms are mutually sufficiently locked when they are stacked on top of each other.
- the object is achieved in that at least the longitudinal beams each consist of a closed hollow profile which is approximately rectangular in cross section, which is composed of two parallel vertical webs and horizontal belts, and that, in addition, a walk-in between the longitudinal beams Clamping tread is clamped, which is attached directly to the side members, wherein the tread is U-shaped and its overhead, horizontal web plate serves as a tread and on both sides of the web plate approximately perpendicular downward bent webbing plates are attached to the inner webs of the side members.
- the running plate is at least partially designed as a perforated plate. Although it cannot be avoided on the building site that dirt and building material particles fall through the perforated plate, they cannot collect in the running plate, but continue to fall. The work platform stays clean.
- the work platform is prepared for good stackability if the belt plates are attached to the side members in such a way that the web plate is offset parallel to the surface above the upper belts of the side members; It is particularly advantageous if the web plate projects beyond the upper straps of the carrying frame by about half the width of the belt plates.
- the work platform is designed to be extremely torsionally rigid when the belt plates are welded to the inner webs of the side members, for example by a sequence of resistance spot welds.
- the cross members which are welded to the longitudinal members on the end face of the support frame, can be designed as upright U-shaped bent profiles, the vertical profile web of the respective because of the cross member, the supporting frame is edged at the end face and the profile straps can be released so that the profile web also covers the hollow profile of the respective longitudinal member.
- the entire surface of the end face of the support frame is available, for example for fastening connecting elements, and the hollow profile of the side members can also be closed on the end face.
- the upper profile belts underlay the tread plate, so that it is also supported on the end faces of the support frame in such a way that deflection is avoided.
- the lower profile belts also end above the lower belts of the longitudinal beams, when several work platforms are stacked, the running leche and thus the entire work platform in the next higher work platform are safely oriented, at least in the important one for safe stacking Direction across the longitudinal extension of the work platforms.
- Such an arrangement is quite informal if the cross members have the same support frame uniform height as the side members: at the top the overhang over the side members is just as large as below the indentation over the side member lower edge.
- the work platform can be easily attached to the scaffolding if at least two hook-shaped brackets are provided on each end face of the support frame and are fastened to the cross beams and overlap the cross bars of the scaffolding.
- adjacent work platforms can be mounted with their end faces lying close to one another on the same cross member if the brackets on the cross members of the support frame are parallel to the end faces.
- the direction is so arranged and spaced from the longitudinal sides of the support frame formed by the longitudinal members that they are offset against the brackets on the adjacent cross member of another same support frame in such a way that when the support frame is aligned, the holders on the same Cross bar can be arranged.
- brackets on the cross members are provided in pairs and in the vicinity of the longitudinal members so that the load on the working platform is introduced into the scaffolding as evenly as possible.
- the brackets can be welded to the cross members of the supporting frame in a simple and effective manner.
- the work platform designed according to the invention is a particularly long component, then it can be advantageous for the rigidity of the work platform if at least one stiffening strut is clamped between the longitudinal beams on the support frame parallel to the cross members , expediently approximately in the middle between the cross members on both sides.
- the invention reduces the components required for a work platform to a few, simply designed and therefore also inexpensively producible components, which, however, overall allow the provision of a very dimensionally stable and heavy-duty work platform with a consistent lightweight construction.
- FIG. 1 is a top view of a working platform according to the invention
- 2 shows an associated front view in section BB from FIG. 1, in which the working platform is shown in its position of use
- FIG. 3 shows a section AA from FIG. 1,
- Fig. 4 shows a detail C from Fig. 3 and
- FIG. 5 shows a detail D from FIG. 1, each enlarged
- FIG. 6 shows the front view of FIG. 2, likewise enlarged
- a working platform essentially consists of a supporting frame 1, a running plate 2 and hook-shaped holders 3.
- the support frame 1 is composed of two side members 11 and two cross members 12, which are welded together in the corners 13 of the support frame 1. Approximately in the middle between the cross members 12, a stiffening strut 14 is clamped between the side members 11 and is also integrally connected to them by welds.
- the crossbeams 12 form on the end face of the support frame 1 closed surfaces on which the brackets 3 are welded so that the hook 31 provided on them points downward in the position of use so that the hooks kentation 32 each end face la of the support frame l can cross a cross member of the scaffolding.
- the profile of one of the cross members 12 and its relative position on the longitudinal members 11 can be clearly seen; it is composed of a U-shaped profile web 12a and an upper and a lower profile belt 12b, 12c, which is bent over by the profile web 12a.
- the cross member 12 is clamped between the side members 11 so that its upper profile belt 12b protrudes over their upper straps 11a by a height j (FIG. 6).
- the protruding gussets 12d formed in this way in the width of the longitudinal members 11 are notched on the cross members 12 (FIGS. 6, 7).
- the lower profile belts 12c according to FIG. 4 are indented into the supporting frame 1 by a height h 2 over the lower belts 11b of the side members 11.
- the height h ⁇ is at most as great as the height h 2 , so that (Fig. 8) stacked working platforms can be stacked easily and safely. If the heights h- j ⁇ and h 2 are the same, then the cross members 12 also have the same height H as the longitudinal members 11.
- the brackets 3 are not provided in mirror image on the support frame 1 with respect to the crossbeams 12, but rather are set in pairs on its two end faces la so that adjacent support frames 1, 1 'can be placed on the same crossbeam of a scaffolding, their long sides lb but are still flush. 7, the situation is easy to see because the non-visible brackets 3 are also indicated on the end face 1 a lying in relation to the plane of the drawing.
- the brackets 3 are all welded to the profile webs 12a and (FIG. 5) are provided in one piece with a bracket plate 33.
- the running plate 2 is also (FIG. 6) U-shaped.
- a web plate 22 is provided between the belt plates 21, the upper side 22a of which, in the position of use, forms the running surface 20 (FIG. 1).
- Its lower side 22b rests on the upper profile belts 12b of the crossbeams 12, while the part of the belt plates 21 which extends into the support frame 1 is connected to the inner webs 11c of the side members 11 so as to lie flat against them, the simplest as already above mentioned by means of resistance spot welding 4.
- Any stiffening strut 14 that may be provided is best welded to the longitudinal beams 11 by means of a fillet weld.
