Supporting steel pipe truss concrete laminated slab
The invention discloses a bearing steel pipe truss concrete laminated slab which 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 an upper arc section, a lower arc section and a straight rod between the upper arc section and the lower arc section, a plurality of transverse reinforcing steel bars are arranged in the reinforced concrete bottom plate, the lower arc section of the wave-shaped reinforcing steel bar is transversely bent, or the lower section of the straight rod and the lower arc section are transversely bent together, so that the flipper structure is formed. The flipper structure is embedded into the reinforced concrete bottom plate, the vertical lower section of the straight rod is embedded into the concrete bottom plate, at least one transverse steel bar penetrates through the flipper structure or is arranged below the flipper structure in a cushioned mode, and the transverse steel bar and the flipper structure are bound or welded into a whole. And the overall structural stability of the steel pipe truss prestressed concrete laminated slab is better.
本发明公开了一种承托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上弧段、下弧段以及上弧段与下弧段之间的直杆，所述的钢筋混凝土底板内设置有多根横向钢筋，所述波浪形钢筋的下弧段横向折弯或直杆下段与下弧段一起横向折弯，形成脚蹼构造，脚蹼构造嵌入钢筋混凝土底板内，直杆竖向下段嵌入混凝土底板内，至少一根所述横向钢筋穿过脚蹼构造，或垫于脚蹼构造下方，横向钢筋与脚蹼构造绑扎或焊接成一体，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。
