Composite floor slab and construction method thereof
The embodiment of the invention discloses a composite floor slab and a construction method thereof. According to one specific implementation mode of the composite floor slab, the thickness of a concrete body of a prefabricated bottom plate of the composite floor slab is 20-45 mm, fine aggregate concrete with the compressive strength not lower than 50 MPa is adopted, the size of the prefabricated bottom plate in the short length direction is not smaller than 1500 mm, a steel bar truss is pre-buried in the long length direction of the prefabricated bottom plate, a combined compression rod is arranged on the upper portion of the steel bar truss, and the combined compression rod is connected with the prefabricated bottom plate in a clamped mode. Short-direction load-bearing steel bars are pre-buried in the direction perpendicular to the steel bar trusses, in the demolding, transporting and hoisting processes of the prefabricated bottom plate, no less than one temporary reinforcing rod is arranged in the direction perpendicular to the length direction of the steel bar trusses, and the temporary reinforcing rods are connected with all the steel bar trusses at the crossed positions through lock catches. And the temporary reinforcing rods are dismantled and recycled after the prefabricated bottom plate is installed. The prefabricated bottom plate is large in width, the number of joints of the composite floor slabs is small, the applicability to residential buildings is high, the using amount of the steel bar trusses is small, and the field steel bar binding amount is small.
本公开的实施例公开了一种叠合楼板及其施工方法。该叠合楼板的一具体实施方式包括：叠合楼板的预制底板混凝土主体厚度为20～45mm、采用抗压强度不低于50MPa的细石混凝土，预制底板长度较短方向的尺寸不小于1500mm，沿预制底板长度较长的方向预埋有钢筋桁架，钢筋桁架上部设置有组合受压杆，垂直于钢筋桁架方向预埋短向受力钢筋，预制底板脱模、运输、吊装过程中，垂直于钢筋桁架长度方向设置有不少于一根的临时加强杆，临时加强杆与所有钢筋桁架在交叉位置采用锁扣连接。临时加强杆在预制底板安装完成后拆除循环使用。本公开预制底板宽度大，叠合楼板接缝少，对住宅建筑适用性强，钢筋桁架用量少，现场钢筋绑扎量小。
