Steel bar truss floor support plate is that the reinforcing bar in floor is processed into steel bar girder using import equipment in factory, and by steel
Muscle truss is with galvanized steel plain sheet in the integrally welded gang form of factory.The template system be by the reinforcing bar in concrete floor with
Construction formwork is combined into one, and composition one can bear the load-bearing structure of water-bearing concreae deadweight and construction loads in the construction stage
Part, and the component can use in the construction stage as the lateral support of girder steel.In service stage, steel bar girder is total to concrete
With work, working load is born.
At the construction field (site), steel bar truss floor support plate can be laid immediately on girder steel, then carries out simple bar bender
Journey, can casting concrete.It need not be set up using the template and scaffold, the zinc-plated profiled sheet in bottom only do template use, no
The problem of substituting steel bar stress, therefore being not required to consider fire prevention spraying and Corrosion Maintenance, also, arrangement of bar is uniform, upper and lower two layers of steel
Muscle spacing and thickness of concrete cover can be fully guaranteed, and advantage is created to improve floor slab construction quality.When pouring
After building concrete formation floor, there is Bars In Poured Concrete Slab integral rigidity is big, anti-seismic performance is good, shock resistance is good, water resistance is good etc.
