Definitions

• the invention relates to a frame element consisting of two stands rigidly connected to one another in the region of their ends by horizontal cross members, preferably tubular in cross section, for a vertical scaffolding frame of a stationary and / or movable scaffolding made of prefabricated components, the frame element for releasable connection horizontal, rectangular covering platforms, which can be placed on the cross members or similar elements of two adjacent frame elements, overlapping the cross section of the respective cross member, and thereby define the distance between the associated scaffolding frames and which are equipped with access hatches and delimiting longitudinal and / or transverse shelves can, with diagonal longitudinal and / or transverse struts and / or longitudinal and / or guer running railings and / or intermediate holes or other components that can be fastened to the frame element.
• Scaffolding made of prefabricated components that can be fixed to the structure and, if necessary, can be converted into movable scaffolding has long been known.
• a comprehensive application of these scaffolding stands in contrast to the fact that the required covering platforms cannot be variably connected in height to the scaffolding frames and, in particular, also not on the completely constructed scaffolding at will and without great effort can be added and removed or moved to different heights.
• the closures which are generally used to connect the other components to the uprights are usually susceptible to wear, require considerable assembly and disassembly work and are also a hindrance when the frame elements are transported and stacked.
• connection of the spars and struts is fixed to certain heights by the stationary scaffolding and is not flexible enough to be able to be used successfully on a mobile scaffolding, on which these heights have to be made much more variable.
• the laterally delimiting scaffolding frames also differ from the others by rigidly attached ladder rungs for the ascent, so that a second type of frame elements must be provided.
• the invention is therefore based on the object of designing a frame element of the type specified in the introduction in such a way that the disadvantages of the known scaffold frames are eliminated and, in particular, covering platforms can be removed, moved around and hung in as desired on the completely constructed scaffolding, the connection of all components to the stands is possible in a simple manner with similar connection elements and in a relatively small-pitched height grid, and the frame elements can also be equipped with crossbars serving as ladder rungs.
• the frame elements should be easy to stack and designed so that none of the side surfaces parallel to the processed building are preferred and each of these side surfaces can be used as a working front.
• the object is achieved in that the stands in a manner known per se at their one end each have a first part which closes the respective stand, for example an integrated tube piece, and - J -
• a complementary second part which projects above the respective stand, for example a bolt piece, has a lockable plug-in coupling that the connections of the crossbeams on the stands are provided with torsion-resistant stiffeners, which preferably stabilize the rectangular shape of the frame element and the upper cross-member is continuous and connected directly and the lower cross-member is bent on both sides down to the first stiffeners on the stands.
• a preferred embodiment of the frame element according to the invention is obtained when the lower crossmember consists of two short, horizontal first bracket pieces connected to the uprights at the same height, one at each of the free ends of the bracket pieces facing each other downwards pointing, together with the associated bracket piece forming a respective first stiffening bracket and a horizontal strut attached to the bracket on both sides and provided at a vertical distance from the axis of the bracket pieces.
• the strut and the tabs are not used as a support or connecting element and can therefore be made relatively light without the stiffening of the Frame element at the lower end would be at risk.
• the tabs are formed as a sheet metal profile and / or the strut and / or the tabs have a rectangular, preferably flat, rectangular cross section. It is particularly advantageous if the lower crossbar is attached to the uprights in such a way that the underside of the strut is approximately flush with the lower ends of the uprights, because on the one hand the offset of the crossbar crosses the neighboring decking platform to a large extent and on the other hand not below the the lower ends of the stand is overhanging, so that the upper crossmember can be provided in the immediate vicinity, but nevertheless at the upper end of the stand.
• a particularly favorable version is one in which the console pieces of the lower crossmember are fastened to the brackets as far as above the associated strut and have such a distance from the upper crossmember of the next frame element that adjoins them down that a cross section that can be placed on the upper crossmember the overlapping connecting element of a covering platform or the like can be attached to or removed from the upper cross member with the plug coupling acting.
• the covering platform can also be removed from the fully installed scaffolding at any time and, if necessary, re-attached at another location.
• console pieces of the lower cross-member are still available for connecting elements of other components when a covering platform rests on the adjacent upper cross-member of the next frame element, so that the corresponding node of the scaffold frame can be used for several components at the same time.
• the dimensional stability of the frame element can be Improve if the upper crossbeam is connected on both sides to the stiffeners, which form second stiffeners and which are connected to the uprights and which are advantageously connected to the uprights by short, horizontal second bracket pieces suitable for connecting decking platforms, struts, spars, shelves or other components could be. In this way, a further connection element can be fastened to the relevant node of the scaffold frame. If it is ensured that the vertex of the upper crossbar is approximately flush with the upper ends of the uprights, the ends of the uprights are not overhanging and the crossbars adjacent to the junction are closely adjacent or lie one on top of the other; the size of the offset of the lower crossbeams can thus be limited.
• a frame element according to the invention can be used extremely variably if short, horizontal third bracket pieces are provided on the stands between the cross beams, which are suitable for connecting decking platforms, struts, spars, shelves or other components; these third bracket pieces can be provided in whole or in part facing the field between the stands, and it is expedient if the third bracket pieces are at least partially provided in pairs at the same height. It is thus possible to provide components both in the end faces and in the side faces of the scaffolding, and to maintain a certain symmetry of the scaffolding, so that neither of their two side faces is preferred. This is particularly advantageous for mobile scaffolding. Cross bars serving as ladder rungs can be placed on the console pieces.
• Compatibility of the frame elements for both types of Scaffolding is further improved if the third bracket pieces are attached to the uprights in such a way that, together with the upper cross members, they form a grid of the same grid height. This grid is not disturbed by the nodes of the scaffolding. It determines the possible spacing of the ladder rungs when the (third) bracket pieces are connected to one another by the (superimposed) cross bars, and enables the height offset of covering platforms within the height of the frame element according to the invention.
• connection elements of all components that can be connected to the uprights can be largely uniform if the upper crossmember and / or the diagonal bars and / or the bracket pieces have a similar cross section. In this way, these cross sections can always be covered in the same way if the connecting element is fastened to the component in space without regard to the direction of the component in such a way that it can always slide vertically from above over the cross section, even if it is not rotationally symmetrical is formed, but instead is preferably composed of a first lower, rectangular partial cross section and a flush adjoining upper, preferably semicircularly curved second partial cross section at the top.
• Such a cross-section combines a high section modulus against deflection with the possibility of conveniently attaching the corresponding connection element while avoiding voltage peaks in the components involved.
• the lightweight construction of such a frame element is promoted if its components are connected to one another consistently or partially by means of weld seams and / or are designed as preferably extruded hollow profiles.
• the frame elements are easy to stack if the width of the cross sections of the cross members and the third bracket pieces is dimensioned such that their connections on the stands are slightly retracted opposite them.
• the frame elements according to the invention have made it possible to design a modular scaffolding both stationary and transportable, which can also be adapted to changing conditions at the construction site at any time, even in a completely assembled state, so that expensive transportation and extensive storage of the required components are avoided can.

• the scaffold frame G ' can easily be replaced by a scaffold frame G.
• the scaffold frames G, G ' are connected to one another by covering platforms B, diagonal longitudinal struts S and longitudinal railing rails GH and intermediate rails ZH.
• the covering platforms B are partially equipped in a known manner with steps D and - omitted in the drawing - longitudinal and transverse rims.
• a frame element R according to FIGS. 4 and 5 consists of two parallel, tubular stands 1, which are rigidly connected to each other at their upper and lower ends 11, 12 by an upper cross member 2 and a lower cross member 3, so that a torsionally stiff, stable component is created.
• a plug-in coupling 4 is formed (FIGS. 2 and 3) in that the upper ends 11 of the stand 1 are designed as bolt pieces 41 and the lower ends 12 as pipe pieces 42, these being Pipe pieces 42 in a simple manner each form one part of the stand 1.
• a bolt lock interlocks the two parts 41, 42 in each of which there are securing holes 13 for this purpose, which can be brought into alignment. Accordingly, several frame elements R can be placed on top of one another; where the plug-in couplings 4 are formed, the upper and lower cross members 2 and 3 are each directly adjacent.
• the upper cross member 2 which is designed as a linear profile piece, is welded to the uprights 1 on both sides; its apex 21 is with the upper end 11 of the stand 1 flush, on which the lower end 12 of the next higher stand 1 rests on the complete frame G.
• the clamping of the crossbar 2 is relieved by diagonal bars 22, which are used in particular to derive the support forces of a covering platform B resting on the crossbar 2 into the uprights 1 and in each case by means of a short horizontal first bracket piece 23 welded to the diagonal bar 22 below Stand 1 are connected.
• bracket piece 23 is also connected to the stand 1 by a weld seam, for each of the gussets between the crossbar 2 and the stands 1 there is a second stiffener VI with respect to first stiffeners V2 on the lower crossbar 3 this area and the frame element R as a whole.
• the cranked at both ends of the lower crossbar 3 comprises a strut 30, on both sides of which are welded vertically upward, sheet-metal tabs 31 are welded, each spaced by the width b from the adjacent stand 1.
• the tabs 31 connect the strut 30 to the second bracket pieces 32 welded to the outer sides of the tabs 31, which are connected on the other hand to the stands 1.
• the bracket pieces 32 are arranged offset against the strut 30 by the height h on the tabs 31.
• the strut 30 is provided with respect to its underside 30a shifted upwards by a slight indentation e from the respective lower end 12 of the stand 1, so that it is spaced from the upper cross member 2 by this amount, as is particularly the case in FIG. 3 is easy to recognize.
• bracket pieces 16 are also welded to the uprights 1, either in the space located in the frame element R between the uprights 1 or in an angularly offset arrangement, not shown in the drawing, for example for connection ⁇ ßssende components that extend in the direction of the end faces of the scaffolding.
• the bracket pieces 16 point inwards on the frame element R and are generally arranged in pairs at the same height as in FIG. 4; Fig. 5 shows that irregular arrangements are also possible.
• All console pieces 16, 23, 32, the upper cross-member 2 and the diagonal bars 22 are all of the same cross-section Q2 (indicated in FIG. 4 in the upper cross-member 2), which consists of a first lower, rectangular partial cross-section Q2 'and an upper, semicircularly curved second partial cross section Q2 "which adjoins it flush.
• the cross section Q2 (FIG. 3) is well suited for connecting the connecting elements AE to the structural element to be connected to the scaffold frame G. elements.
• the connection elements AE are hook-shaped and slide over the cross section Q2 and are secured there if necessary.
• FIGS. 1 and 4 shows that the bracket pieces 16 together with the upper crossbar 2 form a (height) grid with a consistently constant grid height r, so that the scaffolding can be varied as desired without special Components would have to be provided.
• the frame elements R are easily stackable (FIG. 6) because the cross sections Q1 and Q2 of all the components between the uprights 1 are slightly drawn in opposite to them, so that the frame elements R can be stacked on top of one another to save space. They are relatively light, because most components can be easily and inexpensively manufactured as extruded hollow profiles.
