1. Reduce construction time. The bottom plate of the structure can be removed without casting after the cement is poured. Compared with the conventional method, the construction time can be greatly shortened, the on-site steel bar binding work is reduced by 60% to 70%, and the construction period is shortened by 20% to 40%. The reasonable force mode of the truss can better improve the rigidity of the floor slab, thereby reducing or eliminating the need for temporary construction support and turnover materials.

2. Reduce material costs. No die.

3. Reduce labor costs. The work of tying steel bars during construction is greatly reduced, thereby reducing labor costs.

4. Compared with the profiled steel plate, the same load is used, the thickness of the floor slab is reduced by about 20 mm, and the self-weight of the slab is reduced. It can also be used as a two-way board, without fireproof coating, just like the cast-in-place board.

5. Construction accuracy is high.

Since the laying of the steel bars is carried out according to the pre-design requirements, the reinforcement of the concrete is not ensured during the laying process, thereby ensuring the dimensional accuracy of the concrete protective layer. After the material of the supporting steel bar has been subjected to rust removal and cold drawing treatment, the tensile strength can be increased from 300 cattle per square meter to more than 500 cattle per square meter, and the strength is increased by more than 60%; and the seismic capacity is improved, and at the same time, the material selection of the truss steel is Calculated and molded on high-precision equipment, it can save more than 20% of the cost of construction. To apply to a larger span floor, adjust the height of the truss and the diameter of the bar to meet the requirements.
