Definitions

  • the invention relates to a lattice girder composite element in particular for the production of partially prefabricated reinforced concrete slab elements having at least two lattice girder parts which are arranged one behind the other in the longitudinal direction and which each have at least two lower girders and one upper girder connected to the lower girders via bars.
  • Such lattice girder composite elements are very often used in the production of partially prefabricated reinforced concrete slab elements.
  • the lower chords possibly together with the surface reinforcement, embedded in a thin slab of concrete and encased in concrete, the upper chords and the upper chords with the lower chords connecting rods protruding partially from the prefabricated concrete element.
  • the lattice girder composite element gives the prefabricated concrete element during transport and up to at least partial curing of the introduced on the site site concrete the necessary flexural rigidity, which depends significantly on the dimension of the upper flange and determined in element ceilings depending on the span of the composite construction, the number of necessary mounting underpinnings.
  • the invention has the object to provide a lattice girder composite element, with which the above-described Disadvantages can be avoided and the total cost-effective production allowed.
  • the invention solves the problem by at least one with the upper chords of the lattice girder parts each firmly connected rod-shaped connecting element.
  • a first portion of the rod-shaped connecting element with the upper flange of the first lattice girder part and a second Section of the rod-shaped connecting element is firmly connected to the upper flange of the second lattice girder part, wherein it has been found to be favorable when the two lattice girder parts are arranged in abutment.
  • the connecting element is welded to the upper chords of the lattice girder parts, wherein a practically easy to implement solution provides that the connecting element is firmly connected to the lower girths facing sides of the upper straps.
  • the two lattice girder parts are connected to each other by welding at least one connecting element, which is formed by a round steel according to a further embodiment of the invention.
  • the welding can be done by seam welding with a suitable seam length.
  • At least one further connecting element with a lower flange of the first lattice girder part and a lower flange of the second lattice girder part is firmly connected, preferably welded. It has also been found to be particularly advantageous if the lattice support composite element has at least the same static properties, in particular the same bending and buckling stiffness as the individual lattice girder parts, and the lattice girder composite element is rigid.
  • the invention further provides that the grid of connecting the upper straps with the lower straps rods over the entire length of the lattice girder composite element runs evenly.
  • the diameter of the connecting element (s) necessary for achieving the same static properties in the lattice girder composite element is determined, the two lattice parts are arranged according to their grid and then a connecting element, having at least the determined diameter, welded to the two upper chords of the lattice girder parts.
  • a particularly cost-effective solution is achieved when, as a further embodiment of the invention provides, are used as fasteners structural steel residues.
  • lattice girder composite element 1 has two lattice girder parts 2, 12 which are arranged in abutment, ie their front sides touch each other in a bump plane 8.
  • Each lattice girder part has a top flange 3, 13 and two with the top straps 3, 13 via bars 7, 17 connected bottom straps 4, 14 on.
  • the two lattice girder parts 2, 12 are arranged one behind the other in such a way that the grid of the rods 7, 17 runs uniformly over the entire length of the girder composite element 1, which has proven to be advantageous for introducing transverse iron and for stacking the girder composite elements 1.
  • connection of the two lattice girder parts 2, 12 takes place in the embodiment shown on the one hand via a connecting element 5, in a first section A with the top flange 3 of the first lattice girder part 2 and in a second section B with the top chord 13 of the second lattice girder part 12 via welds connected is.
  • connection means 6, 6 ' are each connected to the lower chords 4, 4' of the first lattice girder part 2 and the lower girdles 14, 14 'of the second lattice girder part 12.
  • the bottom straps 4, 4 'and the other connecting means 6, 6' could also be arranged on the inside of the rods 7, 7 '.
  • the device 20 comprises a machine frame 21, on which a holding device 22 for the connecting elements 5 is arranged, wherein the connecting elements 5 of the holding device 22 via a feed device 23, which may be associated with a straightening machine, for example.
  • a height-adjustable holding device 24 is arranged on the machine frame 21.
  • a beam 25 with holding means 26 and a welding device 27 is arranged.
  • the connecting element 5 brought by the holding device 22, 24 from below to the desired position and welded there by means of the welding device 27 to the upper chords 3, 13.
