Galvanized Steel Angle truss steel joist Hangers truss steel joist

Set up temporary support: basically the same as the ordinary cast-in-place reinforced concrete floor slab;no temporary support: before the concrete is solidified, the self-weight of the formwork, the weight of the concrete and the construction load are all borne by the steel truss, and the concrete is solidified under the deformation of the steel bar truss floor bearing plate, and the self-weight of the floor slab will not make the concrete at the bottom of the slab produce tensile force.

The bearing capacity of the floor slab:

In the use stage, the upper and lower chord reinforcements of the reinforcement truss work together with the concrete, and the floor slab has the same mechanical performance as the reinforced concrete superimposed floor slab, and although the tension reinforcement stress is advanced, its bearing capacity is the same as that of the ordinary reinforced concrete floor slab.
