Definitions

  • the invention relates to a vertical handle for a scaffold such as a scaffolding or facade scaffolding, in particular a modular scaffold, for example known from the document DE 1 02 44 239 A1 ,
  • a scaffold according to the present invention comprises further scaffolding elements such as horizontal bars, diagonal struts or running surfaces.
  • a vertical handle of a modular stand comprises at least two tubes which can be connected to each other.
  • a scaffold comprises at least four vertical struts, which are interconnected by horizontal bars and / or running surfaces.
  • diagonal struts can be attached, in particular to the vertical stems, in order to mechanically stabilize the framework.
  • a vertical post for a modular scaffold may be formed of scaffolding tubes having an outer diameter of, for example, 48.3 mm and a wall thickness of, for example, 3.2 mm. Tubes of these vertical stems may have at their upper end pressed smaller tubes with an outer diameter of, for example, 38 mm and a wall thickness of, for example, 3.2 mm, whereby the vertical stems can be put on each other.
  • the smaller tube may additionally be perforated in order to be able to make a compression with the larger tube.
  • the load capacity of a scaffold is designed so that the scaffold can cope with the usual requirements. For exceptional loads, however, the carrying capacity of a scaffold designed in the usual way is insufficient.
  • a vertical stem for a scaffold comprising at least two interconnected or connectable tubes which are inserted into each other by means of a tube with a smaller diameter or can be inserted into each other.
  • a reinforcing tube for reinforcing the smaller diameter tube.
  • a reinforcing tube instead of a reinforcing tube and a round steel can always be used, but this has a higher weight result.
  • steel another material can be used, so that in general a pipe or rod can be used.
  • the cross section can be round or angular.
  • the reinforcing tube is a separate component, which is independent of other elements of the vertical stem and of elements of the associated framework. The reinforcing tube can thus be used if necessary and in addition to the other elements of the framework.
  • the invention is based on the finding that it is sufficient to improve the load-bearing capacity of a scaffold under exceptional loads, to reinforce the claimed vertical stems in the connecting region between two tubes and that for this purpose an additional reinforcing tube or a reinforcing rod suffices. It is thus possible to improve common scaffolding without much effort so that they are more sustainable.
  • a reinforcing tube protrudes in the mounted state relative to the vertical stem into which the reinforcing tube has been inserted for purposes of reinforcement. Optically, then advantageously a reinforced vertical stem can be easily detected.
  • the reinforcing tube may be the same length as the small diameter tube. It can also be longer or shorter. It is important that the reinforcing tube is arranged so long and / or in a vertical stem that the transition region between two tubes of a vertical stem reinforced becomes. The same applies here and below in principle for a rod.
  • the Verstörkungsrohr is inserted in one embodiment in the tube with the smaller diameter.
  • the carrying capacity of a conventional scaffolding can be increased without having to change the scaffold in any form visible from the outside.
  • the vertical stem comprises one or more retaining elements by which the reinforcing tube can be held in the smaller diameter tube. To improve the carrying capacity, it is sufficient to insert the Verstörkungsrohr in the pipe with the smaller diameter. It is then held by the holding means in position immediately, so that the handling effort is low.
  • the one or more holding elements are preferably part of the Verstörkungsrohrs and preferably exclusively.
  • a conventional vertical stem does not need to be altered in any way in this embodiment in order to increase its carrying capacity by means of Verstörkungsstube.
  • a cap or a widening may be provided at the upper end of the Verstörkungsrohrs.
  • the diameter of the cap or widening is chosen so that the widening or the cap can rest with its edge on the tube with the small diameter. The expansion or the cap can thus hold the Verstörkungsrohr in the desired position.
  • at the Verstörkungsrohrende may alternatively or additionally be a spring, a holding element or be part of a holding element to hold the Verstörkungsrohr in the tube with the small diameter frictionally.
  • a cap, a flanging or a ring, 2 can be provided above the Verstörkungsrohr above.
  • a sleeve and / or clamping sleeves may be provided and in particular as fall protection and / or as anti-rotation, so for example Absteck-bores of connecting pin and Verstörkungsrohr reliably above each other (for example, during assembly wrapped in tube 48.3x3.2 mm during assembly).
  • Absteck-bores of connecting pin and Verstörkungsrohr reliably above each other (for example, during assembly wrapped in tube 48.3x3.2 mm during assembly).
  • the task is also solved by a scaffold with a vertical handle according to the claims.
  • the framework also generally has horizontal bars, diagonal struts and running surfaces.
  • Vertical handles and horizontal bars are preferably made entirely or predominantly of metal.
  • Running coverings may consist entirely or predominantly of steel, plastic and / or a wooden material.
  • Vertical stems usually include fasteners to attach to it, for example, horizontal bar can.
  • a horizontal bar may have hook-shaped ends for this, which can be suspended in fastening devices of vertical stems,
  • a scaffold within the meaning of the present invention is in particular several meters high, for example at least 3 m high, preferably at least 5 m high. Running coverings are usually distributed over several levels in such a framework,
  • the invention makes it possible that, in addition to increasing the load capacity, the existing structure is not permanently disturbed (for example with regard to corrosion protection).
  • the invention can be easily performed. For example, easy mounting is possible.
  • the position in the connector can be safely maintained, such as by a Locking and / or anti-rotation. It can be avoided subsequent or autonomous falling apart.
  • a stiffening tube or added round steel added to the vertical stem is visible from the outside in order to be able to distinguish the vertical stems with and without restoring plugs. So the carrying capacity can be easily checked.
  • One or more lateral bores on a small diameter tube for one or more male / female screw connections by which the vertical stems can be connected in a tensile strength can also be used in a preferred embodiment after mounting a reinforcing tube.
  • a reinforcing tube used has corresponding lateral one or more holes that allow such use. The one or more holes of the small diameter pipe and the corresponding one or more holes of the small diameter pipe are stacked in the assembled state.
  • FIG. 1 a tube 1 and a tube 2 of a vertical stem for a modular scaffold is shown in fragmentary detail, in the tube 2, a tube 3 is pushed with a smaller or smaller diameter.
  • the outer diameter of the tube 2 is slightly smaller than the inner diameter of the tube 1 and the tube 2.
  • the two tubes 1 and 2 have the same outer and inside diameter.
  • the tube 3 with the smaller diameter has one or more holes, in each of which extends a punctiform compressed area 4 of the tube 2, whereby the tube 3 is connected with the smaller diameter fixed to the tube 2.
  • this type of attachment of the tube 3 with the smaller diameter in the tube 2 is only an example.
  • the smaller diameter tube 3 may be connected to the tube 2 in other ways, such as by a threaded connection.
  • the upper free end of the smaller diameter tube 3 is inserted into a corresponding lower open end of the tube 1, whereby the tube 1 is detachably connected to the tube 2.
  • a Verstörkungsrohr 5 is inserted into the tube 3 with the small diameter.
  • the Verstörkungsrohr 5 is provided at the upper end with a cap 6, which has a slightly larger diameter than the outer diameter of the tube 3 with the small diameter.
  • the outer diameter of the reinforcing tube 5 is slightly smaller than the inner diameter of the small-diameter tube 3.
  • the diameter of the cap 6 is smaller than the inner diameter of the tube 1, so that the cap 6 can be located in the tube 1 as shown.
  • the cap 6 is laterally on the upper end of the tube 3 with the small diameter. The cap 6 protrudes from the tube 3 and is visually easily recognizable, as long as the tube 1 has not been mounted.
  • the lower tube 2 of the vertical stem is provided with a plate 7, which serves for the attachment of horizontal framework elements such as horizontal bars and / or treads.
  • the plate 7 preferably has holes or recesses, can be hung in the horizontal scaffolding elements.
  • FIG. 4 another embodiment of a Verstörkungsrohrs 5 is shown.
  • the upper edge 8 is widened so as to the Verstörkungsrohr 5 in his in the FIG. 1 shown position in the tube 3 with the small diameter.
  • the FIG. 5 shows various views of a Verstörkungsrohrs 5.
  • the view (a) shows the Verstörkungsrohr from one side.
  • the view (b) shows a 90 ° twisted view
  • the view (c) shows a section through the tube.
  • the reinforcing tube is provided with a spring element 10 at one end, which is able to hold the Verstörkungsrohrs by a clamping action in the vertical stem in the assembled state.
  • the spring element 10 protrudes through corresponding openings to the outside on two sides opposite the lateral surface of the tube. Seen in plan view (c), the spring element may be shaped like a double hook. In order to enhance the spring action, this can be seen in a lateral view as shown alternatively or complementarily arcuate in order to achieve a good spring action.
  • the reinforcing tube preferably comprises in its lateral surface one or more Absteckbohronne 1 1, which may be part of a rotation.
  • One or more retaining elements extend in the assembled state into the one or more Absteckbohronne inside and then advantageously prevent twisting of the reinforcing tube fifth
  • FIG. 6 again shows two side views (a) and (b) of a reinforcing tube 5 and a top view (c) on the reinforcing tube 5.
  • This has in the upper region two laterally protruding from the lateral surface dowel pins 12 and 13.
  • the tensioning pin 12 protrudes laterally than the underlying clamping pin 13, the further protruding dowel pin 12 serves as fall protection in the upper region in the assembled state.
  • the deeper-lying clamping pin 13 serves as an anti-rotation device for the reinforcing tube.
  • An anti-rotation device counteracts a rotation of the reinforcing tube or prevents this to z. B. to avoid possible damage by twisting.
  • the two clamping pins 12 and 13 are preferably mutually rotated by 90 ° as shown arranged to achieve mounting and manufacturing advantages.
  • leg spring 14 In the lower region of the reinforcing tube 5, a leg spring 14 is provided.
  • the ends of the two legs are laterally bent as shown and protrude through openings from the lateral surface of the reinforcing tube 5, to serve in the lower area as a retaining fuse.
  • the legs of the leg spring 14 are led out of the tube 5 below. In this way, the leg spring 14 can be easily used on the one hand or can be easily replaced and on the other hand can be so achieve a good spring action.
