Definitions

  • the invention relates to a node for scaffolding or other scaffolding, which have vertically erectable columns and horizontal beams or struts connecting the columns.
  • This node has a holder attached to a column and a head arranged on a support, the head of which is provided with a releasable wedge which can be inserted through openings provided in the holder.
  • a scaffold node of this type is known from DE-PS 24 49 124.
  • this previously known scaffold node it is necessary to insert the wedge through the opening provided in the holder to attach the horizontal supports to the holder.
  • one person has to work in the area of the scaffold node to attach the horizontal beams to the vertical columns, which is why at least two people are required to assemble and dismantle such a scaffold, namely one who holds the respective horizontal beam and another, which ensures assembly at the scaffold node. If the wedge is not driven deeply, the beam, which is initially only connected to a column at one end, hangs heavily.
  • the relatively light items such as carriers can also be handled by a single person.
  • the girders it must be possible for the girders to be able to be attached to the scaffold node without the man involved in the assembly or dismantling of the scaffold having to be active in attaching and detaching the girders to the respective scaffold node.
  • the invention has for its object, a node for scaffolding or the like. to create, which enables the horizontal supports can be attached by means of the wedge before the final fastening such that they are approximately in the desired horizontal position even if they are initially only attached to one end of a scaffold node.
  • the carrier Due to the special bowl-shaped design of the holder attached to a column and the nose provided in the head of the horizontal support, which can overlap the edge of the bowl-like holder, one is able to hang the support on the holder before the wedge is inserted. Since the head is supported with its lower end on the vertical column, the carrier is in an almost horizontal position if it is only attached to the holder and the wedge has not yet been driven in. The carrier does not hang down significantly. This is advantageous both when assembling and when dismantling the scaffold. By driving in the wedge, the carrier is then brought into the desired final horizontal position.
  • the knot according to the invention it is possible to first attach the horizontal beams between two vertical columns without having to work in the area of the knots themselves. If the horizontal supports are temporarily attached, the wedges in question can be driven into the locking position without having to work on the horizontal supports themselves. When the scaffolding is dismantled, the wedges are first loosened, after which the supports can be removed individually.
  • a cup-shaped holder (2) is welded to a vertically erected column (1) of a scaffolding (not shown in detail), which has an approximately flat floor (3) and a circular edge (4) running around its outer circumference.
  • the edge (4) has a cylindrical outer surface (4a) and a conical or conical inner surface (4b).
  • Horizontal supports (6) can be attached to the holder (2) and clamped to the column (1) using the holder (2).
  • Such a carrier (6) is shown in the drawing, but up to a total of eight carriers can be attached to the holder (2) according to the number of openings (5).
  • the carrier (6) is provided at both ends with a head (7) for attachment to the holder (2), which is welded to the carrier (6) in the illustrated embodiment. At the opposite end of each carrier, not shown, an identical head is welded on.
  • the head (7) is angled in a side view, a raised leg (8) being welded to the carrier (6), while a leg (9) projecting perpendicularly therefrom can be supported on the outside of the column (1).
  • a bracket (10) pointing towards the column (1) is attached to the head (7) and extends parallel to the leg (9) with the column (1) but does not come into contact.
  • bracket (10) On the top of the bracket (10) are provided inwardly projecting flanges (12), between which a narrow gap (13) remains free, through which a wedge (14) made of flat material can pass, but not one provided at the lower end of the wedge , on both sides of the projecting pin (15) so that the wedge (14) is captively connected to the head (7).
  • the wedge (14) has a straight front (18) with a protruding nose (19), which prevents the wedge (14) from slipping through the bracket (10).
  • the wedge (14) On the opposite side, the wedge (14) has an inclined wedge surface (20) in the central region, which in the tensioned position interacts with the conical inside (4b) of the edge (4) of the holder (2), as shown in FIG. 2.
  • the straight front edge or front (18) of the wedge (14) presses against both the front end of the bracket (10) and the front edge (17a) of the opening (17) in the leg (9) of the head (7), to thus firmly clamp the carrier (6) with the aid of its head (7) on the holder (2) and the support (1).
  • the upwardly extending leg (8) of the head (7) lies against the outside (4a) of the edge (4).
  • the nose (19) of the wedge (7) normally there is no contact between the nose (19) of the wedge (7) and the outside of the support (1), although this nose (19) extends close to the support (1).
  • the protruding nose (19) of the wedge (14) contributes significantly to the stiffness of the knot when the support (6) is tilted up or bent.
  • the edge (17a) of the opening (17) presses against the straight front (18) of the wedge (14) and thus the protruding nose (19) against the column (1). This guarantees an extremely rigid node connection even under this load.
  • the clear distance between the nose (19) and the column (1) is therefore chosen to be minimal.
  • a protruding rib (21) is provided on the leg (8) of the head (7) and limits the distance by which the head (7) can be raised relative to the holder (2) when the carrier (6) is attached to the holder (2) or removed therefrom. This facilitates assembly and disassembly, especially when the operator is further away from the head (7). Furthermore, the projecting rib (21) contributes to the safety of the knot or the scaffolding, since it limits the undesired sliding of the support (6) to a small extent if the wedge (14) does indeed pass through the slots (5) and (17 ) is inserted, but has not yet been fixed by a hammer blow. It is also conceivable that the fixation of the knot was forgotten by hammering when assembling a scaffold.
  • the rib (21), as shown in the drawing, is chamfered to make installation easier.
  • the lower leg (9) of the head (7) is wedge-shaped and adapted in its outer end to the curve of the column (1).
  • the upstanding leg (8) is also rounded, as shown in FIG. 3.
  • the legs (8 and 9) of the head (7) lie over the full area on the outside of the edge (4) of the holder (2) or the hollow cylindrical support (1) when the wedge (14) in the in Fig 2 shown clamping position.
  • the wedge (14) is pulled up into the position shown in FIG. 1 and folded back so that it does not hinder the attachment and detachment of the carrier (6).
  • the wedge (14) remains in this position because its center of gravity is clearly behind the slot (16) in the leg (8) and above the hollow support (6).
  • the wedge (14) is folded up by hand and through the aligned openings (5 and 17) in the holder (2) or in the leg (9) of the head (7 ) inserted.
  • the wedge (14) can be brought into the desired clamping position by a hammer blow guided from above.
  • the openings (5) of the holder (2) are significantly wider than the thickness of the wedge (14) to be inserted, the columns (1) connected by a horizontal support (6) do not need to be exactly aligned with one another for the assembly of the scaffold.
