Definitions

  • the invention relates to a lattice girder for the underground line and shaft expansion according to the preamble of claim 1.
  • welded lattice girders are used to produce curved expansion frames and as reinforcement in the subsequent concreting.
  • Such a lattice girder is described for example in DE-U-8 020 051 or DE-A-2 951 874. It has three or more parallel belt bars, which are stiffened like a truss by means of individual zigzag bars arranged in zigzag fashion. The kink, shape and cross-sectional stability of this lattice girder is relatively small.
  • the belt bars tend to buckle and buckle under load.
  • the infill bars are individually welded to the belt bars, whereby the many welds cause the material to become brittle. The welds can break under heavy stress, which leads to the rebars being deflected.
  • a significant increase in the bending stiffness and bending load capacity as well as the torsional strength can be achieved by means of stiffening elements arranged centrally between the belt bars, as is evident from DE-A-27 09 242.
  • Composite sheet metal pressed parts are provided here as inner stiffeners, which have laterally projecting, eyelet-like projections, which encompass the belt bars in a form-fitting manner.
  • the sheet metal parts are complicated to manufacture and correspondingly expensive. Their main disadvantage is that they form a considerable splash shadow, so that the perfect bond between the lattice girder and the concrete is not guaranteed.
  • a lighter lattice girder is sufficient, which is simpler in construction and can be constructed accordingly cheaper.
  • a lattice girder should nevertheless have a sufficiently high level of dimensional stability or cross-sectional stability both against bending stresses and against stresses due to buckling and torsion. It should be possible to use it at least partially load-bearing until it is concreted in and its belt bars form the reinforcement of the final reinforced concrete structure.
  • the infill must be designed so that there are no splash shadows when concreting.
  • the object of the invention is now to provide a lattice girder that meets these requirements. According to the invention, this is done by the features defined in the characterizing part of patent claim 1.
  • connecting brackets as stiffening elements of the lattice girder which consist of triangularly curved round bars which are welded with their ends to the belts.
  • connecting brackets as stiffening elements of the lattice girder which consist of triangularly curved round bars which are welded with their ends to the belts.
  • FR-A-1 098 003 it is also known to provide wavy curved round rods as stiffening elements.
  • the lattice girder shown in the figures has three parallel belt bars 1, 2, 3, which form a triangle in normal section.
  • the two upper chords 1, 2 facing the mountains, which are subjected to tensile load, have a smaller cross-section than the lower chord 3, which is subjected to pressure.
  • the belt bars 1, 2, 3 are spatially fixed to one another by means of inner stiffening elements 4.
  • Each stiffening element 4 is made in one piece from a round steel rod.
  • the round steel rod is first bent flat, ie in the plane, in such a way that two equilateral triangles 5 are formed, the tips 7, 8 of which are connected to one another via two short parallel rod pieces 9.
  • the two ends 10 of the rod are collided and then butt welded together.
  • This two-dimensional structure is then deformed in a further work operation to form the three-dimensional stiffening element 4, two kinks occurring at the tips 7, 8.
  • the two triangles 5, 6 of the stiffening element 4 are arranged obliquely to the belt bars 1, 2, 3 and form an acute angle a with them.
  • the stiffening element 4 is symmetrical with respect to a central plane 15 perpendicular to the belt rods 1, 2, 3.
  • each lattice girder segment To connect two lattice girder segments, they are joined together at the joints. At the ends of each lattice girder segment, two angle irons 16 are welded with holes. The segments can then be pushed together at the ends and screwed together.
  • two plates 18 with bores 19 can be welded to the lattice girder segment on both sides.
  • a V-shaped connecting element 20 with two rows of holes 21 is pushed from below onto the ends of two adjacent lattice girder segments and screwed to the plates 18, as can be seen in FIG. 6.
  • the stiffening elements 4 are inserted at a distance from one another between the belt rods and welded manually or with a welding machine. Then the angle iron or the end plates are attached to the ends.
  • the finished lattice girder segments are only finally connected to each other on site to form the expansion frame.
