Definitions

  • the invention relates to a metal stand scaffold for buildings, in particular a tubular scaffold according to the preamble of claim 1.
  • Stand scaffolds of this type can be designed as so-called bar scaffolds.
  • the invention relates to tubular rod structures, the elements of which predominantly consist of steel tubes. With these scaffolds, the standpipes are connected to the various bars, which also consist of pipe sections, via the coupling.
  • the invention relates to modular stand scaffolding, which allow the scaffolding to be largely adapted to the respective building.
  • the couplings are screwless. This makes assembly and disassembly of the scaffolding easier and faster. Nevertheless, the stand scaffold according to the invention is accident-proof, because its couplings can be assembled without error and only with the prescribed elements, but on the other hand can not be unexpectedly released under any circumstances.
  • the invention is based on a previously known stand structure (EU-PS 0 116 679) whose couplings implement a wedge gear.
  • One on a standing element coupling half is designed as a flange ring and forms the slide of the wedge gear, while the other coupling half is provided with a hook to be hung on the flange ring, which ensures the positive connection.
  • the gap for the driving wedge lies behind the hook, so that this coupling half forms the frame of the wedge gear.
  • the driving in of the driving wedge leads to the interlocking parts being braced, the coupling half forming the frame in particular being elastically deformed.
  • Such couplings are functional in stand scaffolding.
  • the driving wedges can be easily driven and unscrewed from unsafe positions when assembling the scaffolding. They can be accommodated captively in the gap, which inevitably guarantees the functional condition of the couplings. You can also run space-saving, so that the coupling halves build small and u. a. assume a crucial weight for the usability of the standing scaffolding.
  • the invention therefore relates to this basic embodiment.
  • the invention has for its object to provide a functional solution to the problem that has arisen by the loosening driving wedges for the safety of metal stand scaffolding of the type described.
  • the previously unused sides of the driving wedge serve as wedge tightening surfaces, while the wedge flank of the driving wedge is assigned to the bottom of the keyway, but does not come into effect with it and therefore does not adversely affect the driving wedge effect.
  • the wedge tightening surfaces form a separating wedge which elastically deforms the coupling half provided with it via the driving wedge gap when it is driven into the keyway when driving with the wedge flank running on the inclined surface of the other coupling half.
  • the invention therefore has the advantage that it avoids the previously occurring dangerous conditions with simple means, namely by a shape of the driving wedge which deviates from the known, and thus retains the basic advantages of the screwless driving wedge couplings.
  • the invention is carried out so that the driving wedge attracts over the full length of the driving path, because the wedge surfaces of the separating wedge start directly on the back of the driving wedge and end at the driving wedge tip. This makes it possible to let the additional preload of the coupling halves with the separating wedge occur with the first hammer blow on the back of the driving wedge and to keep the number of hammer blows low until the final preload.
  • a standpipe (1) of a pipe stand frame (not shown) is connected to a frame latch (2) with the aid of a mechanical coupling.
  • One half (4) of the coupling (3) consists of a ring which is attached to the standpipe (1).
  • the ring forms a flange (5) which forms a conical surface (6) which is inclined upwards in the direction of the standing tube (1) and an oppositely inclined lower conical surface which is designated by (7) and as a bearing surface for a wedge gear (8).
  • It serves to connect the coupling half (4), which is fixed to the standing tube (1) and is formed by the described ring (4), with the other coupling half (9) so as to be vibration-proof.
  • the coupling half (9) consists of a molded part, for example, which has a hollow cylindrical section (10) to which the bolt (2) consisting of a tube is welded.
  • a driving wedge (12) In the front part of section (10) there is a gap (11) for a driving wedge (12).
  • the driving wedge is shown in Fig. 1 in its rest position. He takes this when the driving wedge is in its upper end position. Then the wedge surface (13) of the driving wedge (12) is supported on the lower end of the bottom (14) of the gap (11) with a recess (15) on a shoulder (16) of the bottom.
  • a semicircular thickening (17) which attaches to the driving wedge tip, prevents the driving wedge from being released from the guide slot (11).
  • the driving wedge of the wedge gear is on the annular inclined surface (7) of the frame Flange ring (5) supported by the wedge suit.
  • the opposite driving wedge flank (3) is no longer supported and is also no longer used to tighten the wedge for tightening the clutch.
  • the two side surfaces (40, 41) of the driving wedge (12) form the flanks of a separating wedge and its wedge surfaces. Their levels converge behind its wedge flank (13).
  • a keyway (43) is formed for the separating wedge in the gap (11), the friction surfaces (44, 45) outside of the gap, i. H. converge on the side facing away from the hook (5). From Fig. 2 it can be seen that the inner cylinder (10) interrupts the groove bottom (46) in the gap (11) at (47).
  • the wedge surfaces (40, 41) begin at the edges of the back (46) of the driving wedge (12). Therefore, the separating wedge is tightened simultaneously with the wedge gear. This is also ensured by the parallel wedge surface sides (48, 49), which are located on the wedge tip (15). The keyway side surfaces (44, 45) above the keyway bottom section (50) are assigned to these.
  • the driving wedge (12) is driven by hammer blows on the back of the wedge (51), its tightening surface (13) being above the bottoms (50, 52) of the keyway in the gap (11).
  • the driving wedge is loosened, the separating wedge surfaces (40 and 41) are detached from the groove side surfaces (44 and 45) of the keyway.
  • the wedge is driven, it also moves towards the bottom of the groove, whereby the separating wedge is tightened.
  • the back of the wedge (54), the wedge flank (13) and the wedge surfaces (40, 41) form the edges of a trapezoidal profile which has inclined edges which run symmetrically to a central perpendicular (55).
  • the outer inclined surface (6) and the opposite inclined surface (57) bear against the surfaces (58, 59) of the inside conical hook jaw (60) assigned to them.
  • the coupling half (9) is preferably elastically deformed and in this way brings about the bracing with the other coupling half (4).
  • the end (55) which is to be attached to the driving wedge tip (15) is to be penetrated with a double-head rivet (56).
  • the end (55) therefore consists of a flat profile.
  • the two rivet heads serve to prevent the driving wedge (12) from being driven upwards.
  • an upper wedge lock which prevents the driving wedge from being driven downward out of the gap (11), is not required. If it is provided, it can consist of a lateral thickening of the driving wedge (12).
