Definitions

  • the invention relates to a frame element for a vertical to be erected scaffolding frames of a stationary and / or movable scaffolding made of prefabricated components, consisting of two in the area of their ends horizontal crossbeams with one another in the operating state rigidly connected, preferably circular tubular in cross section Stands with the stands at one end always a first one that closes the respective stand Part, for example, an integrated piece of pipe and on her the other end a complementary second, the respective one Stand protruding part, such as a bolt piece, have a lockable plug-in coupling Connections of the crossbeams to the uprights with torsion-resistant, the preferably rectangular shape of the frame element stabilizing stiffeners are provided and the upper cross-member is continuous and immediate is connected to the stands.
  • Such a frame element is known from GB-A-2 032 504.
  • the invention has therefore set itself the task To design the frame element of the type specified at the outset in such a way that that the disadvantages of the known scaffold frames are eliminated be and especially on the fully assembled Scaffolding covering platforms can be suspended, suspended and attached as required can be the connection of all components to the stands in a simple manner with similar connection elements and possible in a relatively small-scale grid and the frame elements also serve as ladder rungs Crossbars can be equipped.
  • the frame elements should stackable and designed so that none of the preferred side surfaces parallel to the processed building trained and each of these side surfaces as a work front can be used.
  • a preferred embodiment of the frame element according to the invention you get when the lower crossbar is off two on both sides connected to the stands at the same height, short, horizontal first console pieces, each one on each of the free, facing each other Attach the ends of the console pieces pointing downwards with the associated console piece, a respective first one Stiffening tab and one on both sides of the Fastened brackets, with a vertical distance to the axis of the horizontal brace provided for the console pieces.
  • the strut and the tabs are not used as supports or connecting element used and can therefore be relative can be easily formed without the stiffening of the Frame element at the lower end would be at risk.
  • the tabs are designed as sheet metal profiles are and / or the strut and / or the tabs a rectangular, preferably flat rectangular cross section exhibit. It is particularly advantageous if the lower crossbar is attached to the stands so that the underside of the strut is approximately flush with the lower ends the stand is because on the one hand the cranking of the Crossbar the neighboring decking for the most part towering and on the other hand not below the lower ends of the Stand is overhanging, so that the upper crossbar in close proximity, but still at the top of the stand can be provided.
  • console pieces of the lower crossbeam still also available for connecting elements of other components, if a covering platform on the neighboring upper one Crossbar of the next frame element rests so that the corresponding node of the scaffolding frame for several Components can be used simultaneously.
  • the dimensional stability of the frame element can be improved, if the upper crossbeam is on its underside on both sides with second stiffeners, to the Stands connected diagonal bars that are connected advantageous with the stands by short, horizontal, for Connection of covering platforms, struts, spars, shelves or other components suitable second bracket pieces can be connected. This way it is up to the concerned Another connection element is the node of the scaffolding frame attachable. If you make sure that the crown the upper crossbar is approximately flush with the upper ends the stand is so the ends of the stand are not survivable and those adjacent to the node Crossbeams are closely adjacent or lie on top of each other; the size of the offset of the lower cross members is therefore restrictable.
  • a frame element according to the invention is extremely variable usable if on the stands between the cross members short, horizontal, for connecting decking platforms, Struts, spars, shelves or other components suitable third bracket pieces are provided; can these third console pieces all or in part in the Field between the stands pointing, and it is useful if the third console pieces at least partly provided in pairs at the same height are.
  • This makes it possible to use components in both End faces as well as in the side surfaces of the scaffolding to be provided while maintaining a certain symmetry of the scaffolding to maintain, so that neither of their two side surfaces is preferred is. This is particularly the case with mobile scaffolding from Advantage.
  • On the console pieces can be used as ladder rungs serving crossbar be placed.
  • Compatibility of the frame elements for both types of Scaffolding will be further improved if the third console pieces are attached to the stands so that they are together with the upper crossbars a grid is the same Form grid height. This grid is also there not disturbed by the nodes of the scaffolding. It defines the possible spacing of the ladder rungs, if the (third) console pieces through the (attached) crossbars are interconnected, and allows the height offset of topping platforms within the height of the invention Frame element.
  • connection elements of all connectable to the stands Components can be largely uniform, if the upper crossbar and / or the diagonal bars and / or the console pieces have a similar cross section exhibit. In this way, these cross sections can always be overlaid in the same way if the connecting element regardless of the direction of the component in Space is attached to this so that it is always perpendicular from can slide over the cross section at the top, even if it does is not rotationally symmetrical, but instead preferably from a first lower, rectangular partial cross section and a flush one upper, preferably semicircularly curved upwards second partial cross section is composed.
  • Such a Cross-section combines a high resistance moment against Deflection with the possibility of easy application the corresponding connection element while avoiding of voltage peaks in the components involved.
  • the frame elements are easily stackable if the width of the Cross sections of the crossbeams and the third bracket pieces is dimensioned so that their connections to the stands this have moved in slightly.
  • the frame elements according to the invention have made it possible a modular scaffolding both stationary and to be transportable, even in a fully assembled Condition changing conditions at the construction site at any time can be adjusted so that complex transports and extensive storage of the required components can be avoided.
  • the scaffold frame G initially consists of four Scaffolding frame G with frame elements R according to the invention and a scaffold frame G 'with frame elements not according to the invention R 'that here as an ascent to the scaffolding serves.
  • the scaffold frame G ' can easily be replaced by a Scaffold frame G to be replaced.
  • the scaffold frames G, G ' are with each other through covering platforms B, diagonal longitudinal struts S and longitudinal railing spars GH and intermediate spars ZH connected.
  • the covering platforms B are in a known manner partially with hatches D and - omitted in the drawing - Equipped longitudinal and transverse rims.
  • a frame element R according to the invention exists accordingly 4 and 5 from two parallel, tubular stands 1, at their upper and lower ends 11, 12 each an upper cross member 2 and a lower cross member 3 are rigidly connected to each other so that a torsionally rigid, load-bearing component is created.
  • a plug-in coupling 4 is thereby formed (FIGS. 2 and 3), that the upper ends 11 of the stand 1 as bolt pieces 41 and the lower ends 12 are formed as tubular pieces 42 are, these pipe pieces 42 in a simple manner each form in one piece a part of the stand 1.
  • a Bolt lock locks the two parts 41, 42 each with each other, in which for this purpose safety holes 13 are provided, which can be brought into alignment.
  • the plug-in couplings 4 are formed the upper and lower cross members are 2 and 3 each immediately adjacent.
  • the upper crossbar designed as a linear profile piece 2 is welded to the stands 1 on both sides; its apex 21 is with the upper end 11 of the stand 1 flush, on the complete frame G the lower one End 12 of the next higher stand 1 rests.
  • the crossbar 2 is clamped by diagonal bars 22 relieves, in particular to derive the support forces a covering platform B resting on the crossbeam 2 serve in the stand 1 and each by means of a short horizontal, welded to the diagonal bar 22 below first bracket piece 23 are connected to the stand 1.
  • bracket piece 23 also by a weld is connected to the stand 1, results in a total of each of the gusset between the crossbar 2 and the stands 1 one with reference to first stiffeners V2 on the lower one Crossbeam 3 second stiffening V1 of this area and the frame element R as a whole.
  • the lower crossbar 3, which is bent at both ends includes a strut 30 on both sides perpendicular to sheet-metal tabs 31 directed at the top are welded on, each by the width b from the neighboring stand 1 are spaced.
  • the tabs 31 connect the strut 30 with second welded on the outer sides of the tabs 31
  • Console pieces 32 which on the other hand on the stands 1 are connected.
  • the console pieces 32 are against the strut 30 is offset in height by the height h on the tabs 31 arranged.
  • the strut 30 is with respect to its underside 30a by a slight indentation e of the respective provided lower end 12 of the stand 1 pushed upwards, so that they are spaced from the upper cross member 2 by this amount is, as can be seen particularly well in FIG.
  • console pieces 16 welded on, either in the room itself is located in the frame element R between the stands 1, or also in angularly offset, not considered in the drawing Arrangement, for example for those to be connected Components that face towards the end faces extend the scaffolding.
  • the console pieces 16 instruct the frame element R inside and are usually as in 4 arranged in pairs at the same height; 5 shows that irregular arrangements are also possible.
  • All console pieces 16, 23, 32, the upper crossbar 2 and the diagonal bars 22 are all the same Cross section Q2 (in FIG. 4 in the upper cross member 2 indicated), which consists of a first lower, rectangular partial cross section Q2 'and a flush adjoining upper, semicircularly curved upwards second partial cross section Q2 ".
  • the cross section Q2 (Fig. 3) is well suited for connecting the connection elements AE on the components to be connected to the scaffold frame G.
  • the connection elements AE are hook-shaped and slide over the cross section Q2 and are there if necessary secured.
  • FIGS. 1 and 4 shows that there the console pieces 16 together with the upper crossbar 2 Form (height) grids with a constant grid height r, so that the scaffolding can be varied as desired without that special components would have to be provided for this.
  • the frame elements R are (Fig. 6) stackable because the Cross sections Q1 and Q2 of all components between the stands 1 these are slightly drawn in, so that the frame elements R side-overlapping to save space can be. They are relatively easy because of that most components light and moreover as inexpensive extruded hollow profiles can be produced.
