Product Advantage:
1, Steel bars are evenly arranged and the bearing mode is reasonable, which greatly reduces the engineering quantity of temporary support.
2, The double edgefold design can effectively ensure the quality of the engineering.
3, It can shorten the time by reducing 60% to 70% work load of binding steel bars.
4, It has the same mechanical properties and fire resistance as that of traditional cast-in-place floors. Because the bottom mould does not join in the load-baring, it is unnecessary to consider fire proof and anticorrosion.
Compare with common steel decking:
composite Steel decking | steel bar truss decking | |
Final concrete slab | Thick | SHALLOWER, saving space,saving concrete cost |
installation | easy | easy |
reinforcement | Welding steel mesh | Steel bar. Saving cost |
Plate(steel sheet) | AS SHEAR BONE,Bearing the loading after concreting | Just as PERMANENT formwork. .useless after concreting |
Plate Fire protection | demand | No need |
Plate corrosion protection | Maintenance demand.* specially around stud place where sheet harmed after welding | No need Perfect performance in marine environment |
across direction layout | Difficult to design&settle | Easy to settle |
Mechanical property | good | better |
Seismic performance |
bad | good |
Integrate cost | high | low |
Comfort due to slab autooscillation | bad | good |
