Definitions
- the invention relates to a fire-resistant composite girder for supports, light band 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 are connected to the concrete are.
- Roller 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 9o according to DIN 41o2 if they are additionally reinforced by inserted round steel and the concrete is connected to the bridge by means of anchoring agents.
- these known composite beams have the disadvantage that the additional reinforcement and dowelling work is very time-consuming and costly. It is therefore an object of the invention to provide a composite girder of the type mentioned in the introduction, in which the additional reinforcement and dowelling work can be saved without subsequent additional fire protection.
- the object is achieved in such a way that the steel profile consists of an extruded profile which, for example, has an I, , has a profile-like or another open cross-section and the insides of which have protruding thin-walled webs and / or are profiled.
- the projecting thin-walled webs are expediently provided at their free ends with bulge-like thickenings which represent the reinforcement.
- the inner sides of the extruded profile are profiled step-like, sawtooth-like, dovetail-shaped, undulating or in some other way enlarging the surface.
- the protruding thin-walled webs can also be welded to structural steel mat strips or wire grids, which can further improve the load-bearing capacity, particularly in the event of a fire.
- the composite effect is advantageously supported in that the flange ends of the extruded profile are bent at right angles and surround the concrete, so that the concrete is additionally secured against loosening in the event of a fire.
- the extruded profile has different wall thicknesses, in such a way that the webs surrounded on both sides by concrete are thicker than those which are only covered with concrete from one side.
- the transition areas of the webs covered on both sides with concrete to the one-sided concrete walls are thin-walled than the middle parts of the webs.
- the advantages of the composite girder according to the invention can be seen in particular in that it has a fire resistance duration of at least 90 minutes without additional fire protection, e.g. Reinforcements and steel dowels, the subsequent installation of which requires considerable time and cost.
- the increased load-bearing capacity in the event of a fire is e.g. formed by the homogeneous formation of webs and profiles of the inner sides in the manufacture of the extruded profile itself.
- the possibilities of strand. Press technology is limited in terms of 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 method 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 extrusion technology and the concrete filling, without prejudice to the loss of fire protection.
- the composite beam 1 consists of extruded profiles 3, 4, 5 filled with concrete 2, which, for example, have an I (FIG. 1), (Fig. 2), (Fig. 3 and 4) -profile-like cross-section, the flange ends 6 for edging the concrete 2 are each bent at right angles.
- All the extruded profiles 3, 4, 5 shown have on their inner sides protruding thin-walled webs 7 which have bead-like thickenings 8 at their free ends.
- the inner sides are corrugated 9, whereby the adhesion of the concrete 2 in dan extruded profiles 3, 4, 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.
- Fig. 4 e.g. a three-part composite carrier 1 shown, which is composed of three extruded profiles 5 according to FIG. 3.
- This composite carrier 1 can e.g. can be used in a honeycomb-like cell construction for the central support of three adjoining spatial cells, not shown.
