Definitions
- a design with higher clear widths is not common practice in practice, as this results in excessive deformation in the construction state, in particular a deflection of the steel trapezoidal profile.
- a deflection could be limited by using steel trapezoidal profiles with increased sheet thickness, but this would lead to an oversizing of the composite ceiling systems in the final state.
- Another possibility would be to increase the height of the steel trapezoidal sheet profile, which in turn would lead to an increase in the necessary storey height.
- An embodiment for producing a composite ceiling system is described by way of example in German patent DE 42 15 686 C1. With respect to the prior art, there is room for improvement, in particular with regard to increasing the system lengths.
- the steel trapezoidal profiles on a crowning or pre-bending in the delivery state which is introduced contrary to the extent of the expected deflection, which can be determined in advance by means of static calculation. Due to the crowning of the steel trapezoidal profile therefore has a clear width, which is less than the length in unbomb elected state respectively in the construction or final state (system length).
- the clear width of the steel trapezoidal profile can be> 6 m, in particular> 7 m, preferably> 8 m.
- FIG. 1 a perspective view of a steel trapezoidal profile
- FIG. 1 shows a steel trapezoidal profile (1) in a perspective illustration and in FIG. 2 its side view.
- the steel trapezoidal profile has in its transverse extension in cross section a recurring upper flange (1.1) and lower flange (1.2), s. Fig. 3.
- the illustrated steel trapezoidal profile (1) substantially corresponds to the embodiment TRP 200, s.
- the steel trapezoidal profile (1) bends through the weight load with liquid concrete with 90 mm concrete thickness C35 / 45 including reinforcement made of steel with a diameter of 10 mm and concrete cover with 50 mm by about 115 mm.
- the curvature corresponds to a bending radius (R) of about 73,000 mm. Under traffic load there is a permissible deformation of approx. 70 mm.
- the possible clear width can be determined for each yield strength between 350 and 1050 N / mm 2 .
- the deflection in the construction state is then compensated according to the invention by the crowning of the steel trapezoidal profile.
- the invention is not limited to the embodiment shown in the drawing and to the embodiments in the description. Rather, steel trapezoidal profiles with other geometries are applicable and bombable to compensate for the deflection in the construction state. Incidentally, the features are all combined with each other.
