T-shaped steel pipe truss concrete laminated slab
The T-shaped steel pipe truss concrete laminated slab comprises a reinforced concrete bottom plate and a steel pipe truss, a plurality of longitudinal prestressed steel bars are distributed in the reinforced concrete bottom plate, and the steel pipe truss comprises a steel pipe and wavy steel bars welded to the two sides of the steel pipe. The wave-shaped reinforcing steel bar comprises a wave crest section, a wave trough section and a web member between the wave crest section and the wave trough section, the wave trough of the wave-shaped reinforcing steel bar is embedded into the reinforced concrete bottom plate, a plurality of transverse reinforcing steel bars are arranged in the reinforced concrete bottom plate, and welding positions used for being welded with steel pipes are arranged on the two sides of the wave crest of the wave-shaped reinforcing steel bar. The welding positions are arranged at the tangency points where the wave-shaped steel bars intersect with the steel pipes or near the tangency points, and the wave crest sections of the wave-shaped steel bars on the two sides of the steel pipes or the wave crest sections of the wave-shaped steel bars on the two sides of the steel pipes and the upper-section web members are transversely bent together to form truss upper wing outward spreading wing steel bars. And the overall structural stability of the steel pipe truss prestressed concrete laminated slab is better.
本发明公开了一种T形钢管桁架混凝土叠合板，包括钢筋混凝土底板、钢管桁架，所述钢筋混凝土底板内布设有多根纵向预应力钢筋，所述钢管桁架包括钢管和焊接在钢管两侧的波浪形钢筋，所述的波浪形钢筋包括波峰段、波谷段和波峰段与波谷段之间的腹杆，所述的波浪形钢筋的波谷嵌入到钢筋混凝土底板内，所述钢筋混凝土底板内设置有多根横向钢筋，所述波浪形钢筋的波峰两侧有用于与钢管焊接的焊接处，且焊接处设置在波浪形钢筋与钢管相交的切点或切点附近，所述钢管两侧的波浪形钢筋的波峰段或波峰段连同上段腹杆一起横向折弯形成桁架上翼外展翅钢筋，具有提高叠合板内部支承结构的强度，使钢管桁架预应力混凝土叠合板整体的结构稳定性更好。
