Definitions

  • the invention relates to a fire-resistant composite girder for supports, light strip girders or the like, consisting of an open steel profile, the cavities of which are filled with concrete, compound materials being arranged on the inner walls of the steel profile, which project into the cavities filled with concrete, and wherein Steel profile has a web connecting its outer parts, which is surrounded on both sides by concrete.
  • Roll supports filled with concrete in particular wide flange supports, the flanges of which remain unprotected on the outside, are known to have an increased fire resistance duration, e.g. achieve fire resistance class F 90 according to the old DIN 4102 if they are additionally reinforced by inserted round steel and the concrete is connected to the bridge by means of anchoring agents.
  • these composite beams known from DE-AI-2 829 864 have the disadvantage that the additional reinforcement and dowelling work is very time-consuming and labor-intensive.
  • FR-A-382 117 a fire-resistant composite beam is also known, which is composed of individual double-T beams by screwing, which is very expensive.
  • This known composite carrier also comes no closer to the subject of the application than the prior art known from DE-AI-2 829 864.
  • the object is achieved with a composite beam of the type described in the preamble of claim 1 in such a way that the ends of the outer parts of the profile or the profiles are bent at right angles in the concrete enclosing that the web surrounded by the concrete Profile with a one-piece girder cross-section or the webs surrounded by concrete with a multi-part combined girder cross-section are thicker than the outer parts of the profile (s), and that the thick-walled web (s) surrounded by concrete are towards the inside of the beam have to be pointed, thin-walled small webs, the ends of which have bead-like thickenings which are also surrounded by the concrete, the profile including its profilings provided on the inner walls and the webs and bead-like thickenings being designed as a homogeneous extruded profile.
  • the transition regions of the thick-walled web to the outer parts are expediently thin-walled.
  • the inner sides of the extruded profile are profiled step-like, sawtooth-like, dovetail-shaped, undulating or in some other way increasing the surface.
  • the advantages of the composite girder according to the invention can be seen in particular in the fact that with it a fire resistance class according to DIN 18 230 (new) without additional fire protection, such as e.g. Reinforcements and steel anchors, the subsequent installation of which requires considerable time and cost.
  • the increased load capacity in the event of a fire is e.g. through the homogeneous formation of webs and profiles on the inside during the production of the extruded profile itself.
  • the possibilities of extrusion technology are limited with regard to the size of the profiles, but the advantages of the integrated reinforcement and the optimal adhesive bond can be exploited in a number of supporting structures, for which a longer fire resistance is required, without special fire protection measures.
  • the construction according to the invention is particularly economical because the load-bearing capacity of the extruded profile in steel / concrete composite is about 30% higher than that of the pure steel profile, which pays off the additional costs of the extruded technology and the concrete filling, without prejudice to the loss of fire protection.
  • the composite beam 1 consists of extruded profiles 3, 5 filled with concrete 2, which e.g. have a cross-section similar to a profile (FIG. 1 LC - (FIGS. 2 and 3)), the flange ends 6 each being bent at right angles to surround the concrete 2.
  • the extruded profiles 3, 5 shown have on their inner sides protruding thin-walled webs 7, which have bead-like thickenings 8 at their free ends 3, 5 is increased.
  • the central webs 11, 12 surrounded on both sides by concrete 2 are thicker than the other walls, the transition regions 13, 14 of the webs 11, 12 to the flanges 6 are thinner.
  • a three-part composite carrier 1 is shown, which is composed of three extruded profiles 5 according to FIG. 2.
  • This composite beam 1 can e.g. can be used in a honeycomb-like cell construction for the central support of three adjoining spatial cells, not shown.
