Definitions

  • the invention relates to a lattice girder for underground track and shaft expansion according to the preamble of claim 1.
  • Welded lattice girders are used for the construction of arched expansion frames and as reinforcement for the subsequent concreting during the expansion of tunnels and pit sections in pressurized mountains.
  • Such a lattice girder is for example in DE-OS 29 51 874 described. It has three or more parallel belt bars which are stiffened in a truss-like manner 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 use, which leads to the rebars being pulled out.
  • a significant increase in the bending stiffness and load-bearing capacity as well as the torsional strength can be achieved by stiffening elements arranged centrally between the belt bars, as can be seen from DE-OS 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 accordingly expensive. Your biggest disadvantage is that it raises you liche splash shadow so that the perfect bond of the lattice girder with 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 claim 1.
  • the lattice girder shown in the figures has three parallel belt bars 1, 2, 3, which are normal cut to form a triangle.
  • the two upper chords 1, 2 facing the mountains, which are subjected to tensile stress when loaded, have a smaller cross section than the lower chord 3, which is stressed.
  • 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 flat, i. H. in the plane, curved, in such a way that two equilateral triangles 5, 6 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 pushed together 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 enclose 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 used Welded holes. The segments can then be pushed together at the ends and screwed together.
  • two plates 18 with bores 19 can be welded onto 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, 19 are inserted at a distance from one another between the belt bars and welded manually or with a welding machine. Then the angle iron or the end plates are attached to the ends.
  • the ferti Lattice girder segments are only finally connected to one another on site to form the expansion frame.
