Definitions

  • the invention relates to a formwork support for formwork constructions for round buildings with a shape that changes over their height, consisting of a profile support with two flanges arranged at a distance from one another and at least one web connecting the flanges, the support having at least one bend, and on the bend the opposite flange opposite the flange and the web of the profile carrier is provided with an incision transversely to the longitudinal direction of the profile carrier, and at least one correspondingly bent tab bridges the incision, and is connected to the two separate flange parts of the counter flange.
  • the US-PS 17 47 362 shows such a construction of a girder, but it is not a formwork girder, but an arch of a steel structure.
  • the bow is rigid.
  • US Pat. No. 524,807 also shows a steel construction carrier with rigid bends.
  • a foldable formwork is known from US Pat. No. 1,214,233, but it is not very dimensionally stable at the fold points.
  • Formwork girders of the type mentioned at the outset 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 beam 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 in order to be able to use one and the same profile beam for formwork of walls with different kink angles.
  • the object of the invention is to avoid these disadvantages and to provide a formwork support for formwork constructions which is provided with at least one bend and which permits angled bend which is correct in terms of assembly and is technically secure, and a simple correction or change in the articulation angle.
  • the one flange is continuous and bend-deformable to change the bending angle
  • the tab is screwed to the flange parts of the counter flange and has elongated holes which extend in the longitudinal direction of the profile beam and through which the fastening screws protrude.
  • the invention can be used advantageously for formwork beams for buckled walls, which also include “curved” walls approximated by polyhedra.
  • the invention can, however, also be used in formwork construction for beams which do not directly serve as beams for formwork panels, but with an otherwise load-bearing function, e.g. B. are arranged in the scaffolding or work scaffolding of a formwork construction, and there have one or more kinks, for example in the case of a polygonal course of the girder.
  • the invention also enriches the assembly technology beyond the field of formwork construction.
  • the formwork support according to the invention is used in particular in formwork for water towers, television towers, water containers, egg-shaped digesters and the like.
  • the formwork girders which run in height, have been shaped and welded accordingly.
  • the formwork support according to the invention can be adapted in a simple manner to any building shape, its adaptability being determined only by the distance between the bends. Furthermore, the formwork support according to the invention can be quickly reassembled, i.e. H. can be adapted to another formwork with a different curve.
  • the formwork support according to the invention can also be used as a horizontal polygonal pressure or pull ring of a formwork scaffold for round buildings.
  • FIG. 1 shows in view (partially cut) the kink of a formwork beam
  • FIG. 2 shows a section according to 11-11 of FIG. 1
  • Fig. Shows a variant for the tab
  • FIG. 4 shows a formwork beam with an incision for a “convex kink”
  • FIG. 5 shows the same formwork beam in the kinked position
  • 6 and 7 show profile variants for the formwork beam
  • FIG. 8 shows an application example of a formwork beam 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 support 10 is provided with an incision 6 transverse to a longitudinal direction, which extends over the flange 2 (counter flange) opposite the mounting flange 1 and the entire web 3, but not into the continuous mounting flange 1 a 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 buttons of the screws 8 are underlaid by 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.
  • a slightly modified incision 6 'of the counter flange 2 and the web 3 is required, which makes it possible for the continuous flange 1 to 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 formwork beam 10 need not necessarily be an I-beam.
  • the adjustable buckling of the carrier according to the invention can also be achieved with other profile carriers, for. 6 or box section beams according to FIG. 7, in which case 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 bridged here by the tab 7, which is screwed to the counter flange 2.
  • the formwork beam 10 according to the invention is used both as a longitudinal beam and as a pressure ring.
  • the formwork 11 can be easily adapted to any curvature by means of the formwork support 10 according to the invention. It is also possible to adapt the formwork beam 10 used as a pressure ring to any diameter.
  • Several formwork beams 10 are each put together to form a closed ring.
  • the formwork beams 10 are connected, for example, by means of screws.
  • a particular advantage of the formwork beam 10 according to the invention can be seen in the fact that it can be used to form adjustable fish belly beams with its radius.
  • Such fish belly carriers are used for example in dome-like ceilings for water tanks.
