Steel structure truss deck application prospect

Author:admin Date:2012-12-6 11:10:14

Steel structure truss deck is the cast-in-place concrete floor in the upper, lower longitudinal steel structure, and the bending forming of small diameter reinforcement welding, composed of a certain stiffness and can bear the load of the small truss, and the small truss clubfoot and rib height of only 2mm, thickness 0.4~ 0.6mm pressure plate welding. All of these operations are in the factory use of automated production lines completed.

Steel structure truss deck in construction stage, will be under pressure plate are mutually buckled, to hold the concrete, the truss to provide strength and rigidity; in the using stage, steel structure truss is a concrete slab reinforcement, to withstand load. Therefore, it has a pressure plate assembly or a composite slab construction speed advantage, but also has the cast-in-situ integral stiffness, good anti-seismic performance advantages. The use of steel truss plate slab thickness 100~ 200mm, construction stage unsupported span from 3 to 5m, the traditional pressure plate slab thickness more than 110mm, 2.5~3.5m span without support construction stage. The use of steel truss deck is obviously superior to the cast-in-situ plate and pressure plate, the largest unsupported slabs can be achieved 5.4m.
