Definitions

  • the invention relates to a girder, in particular for formwork constructions for round buildings, comprising a profile girder with two flanges arranged at a distance from one another and at least one web connecting the flanges, the girder having at least one kink.
  • Such girders have become known, for example, for formwork of buckled walls, the formwork panels being fastened to a flange of the profile girder. So far, one has separated the profile girder in the kink, cut and welded the end faces according to the kink angle. This method requires a considerable amount of work, which inhibits rapid assembly of the formwork scaffold. In addition, the kink angle of the profile beam can neither be corrected nor changed, for example by one and the same profile beam for formwork of walls to be able to use with different articulation angles.
  • the object of the invention is to avoid these disadvantages and to provide a support provided with at least one kink, in particular for formwork constructions, which enables kinking that is safe and easy to assemble, and easy correction or modification of the kink angle.
  • the invention can be used advantageously for beams of formwork panels for bent walls, which also include "curved" walls approximated by polyhedra.
  • the invention can be used in formwork. construction can also be used for beams that do not directly serve as the formwork for the formwork panels, but with a different supporting function, e.g. are arranged in the supporting frame or working frame of a formwork construction, and there have one or more kinks, for example in the case of a polygon-like course of the girder.
  • the invention also enriches the assembly technology beyond the field of formwork construction.
  • the carrier according to the invention is used in particular in formwork for water towers, television towers, water containers, egg-shaped digesters and the like.
  • round buildings with a changing shape such buildings can have a tulip-like design in the upper area, for example) have been shaped and welded in accordance with their height.
  • the carrier according to the invention can be adapted to any building shape in a simple manner, its adaptability being determined only by the distance of the kinks from one another. Furthermore, the carrier according to the invention can be quickly reassembled, i.e. can be adapted to another formwork with a different curve.
  • the support according to the invention can also be used as a horizontal polygonal compression or tension ring of a formwork scaffold for circular structures.
  • the openings in the flap for the passage of the fastening screws are in the longitudinal direction the elongated holes of the profile beam are formed. The same can be achieved if the tab has a hinge joint in the middle.
  • An exemplary embodiment provides that the tab is screwed to the two flange parts of the counter flange and is bent in accordance with the carrier.
  • two intersecting tabs are fastened to the counter flanges or on the central webs, and are connected to one another by clamping, for example screwed.
  • FIG. 8 shows an application example of a carrier according to the invention.
  • the formwork girder 10 is an I-section girder made of steel with the two flanges 1, 2 and the web 3.
  • the formwork panels 4, which are offset on the edge side, are fastened to the flange 1 (fastening flange), with the help of the spreader bars 5.
  • the formwork beam 10 has an incision 6 transverse to a longitudinal direction, which extends over the flange 2 (counter flange) opposite the fastening flange 1 and the entire web 3, but not into the continuous fastening flange 1 penetrates. Then the carrier parts lying on both sides of the incision 6 are bent against one another in accordance with the required bending angle.
  • the incision 6 is bridged by a tab 7 made of steel, which is connected to the counter flange 2, the nuts 9 being tightened with a torque wrench.
  • the tab 7 expediently has the width of the counter flange 2 and is dimensioned in accordance with the tensile and compressive loads that occur.
  • the connection of the carrier parts, which are partially separated by the incision 6, via the screwed tab 7 is a friction connection.
  • the tab 7 has elongated holes 11, which allow the tab 7 to be adapted to different bending angles.
  • the heads of the screws 8 are underlaid with washers 10.
  • FIG. 3 shows a tab 1 that is particularly easily adaptable to different articulation angles.
  • the tab 7 has a hinge joint in the central region.
  • the holes for the passage of the fastening screws are elongated holes.
  • Fig. 1 shows a kink with a "concave” kink.
  • the measures according to the invention can also be used for kinks with a "convex" kink.
  • FIG. 4 there is a slightly modified incision 6 'in the counter flange cal 2 and the web 3 required, which enables that the continuous flange 1 can be bent in the manner shown in Fig. 5.
  • the cut 6 ' is in turn bridged by a correspondingly bent tab 7 which is screwed to the counter flange 2.
  • the carrier 10 does not necessarily have to be an I-profile carrier.
  • the adjustable buckling of the beams according to the invention can also be achieved with other profiled beams, e.g. 6 or box section beams according to FIG. 7, in these cases too, the counter flange 2 and the web (s) 3 are cut at the kink, but not the continuous flange 1. The cut is also made here the tab 7, which is screwed to the counter flange 2, bridges.
  • the carrier 10 according to the invention is used both as a longitudinal carrier and as a pressure ring.
  • the formwork 11 can be easily adapted to any curvature by means of the supports 10 according to the invention. It is also possible to adapt the carrier 10 used as a pressure ring to each pressure gauge. Several carriers 11 are put together to form a closed ring. The connection of the carrier 10 takes place, for example, by means of screws.
  • a particular advantage of the carrier 11 according to the invention can be seen in the fact that it can be used to form adjustable fish belly carriers in radius or. Such fish belly carriers are used for example in dome-like ceilings for water tanks.
