Steel bar truss prestressed concrete composite slab and manufacturing method thereof
The invention relates to the technical field of fabricated building floors, in particular to a steel bar truss prestressed concrete composite slab and a manufacturing method thereof. The steel bar truss prestressed concrete composite slab is characterized by comprising longitudinal prestressed tendons, transverse hot-rolled ribbed steel bars, a steel bar truss and a concrete curing layer; the longitudinal prestressed tendons vertically connected with the transverse hot-rolled ribbed bars in the horizontal direction are arranged above the transverse hot-rolled ribbed bars side by side, and thelongitudinal prestressed tendons and the transverse hot-rolled ribbed bars are connected to form a latticed plane; the steel bar truss is arranged above the latticed plane and comprises upper chord bars, reinforcing chord bars, lower chord bars and wavy latticed bars; and the longitudinal prestressed tendons, the transverse hot-rolled ribbed steel bars and the steel bar trusses are connected withone another and then cured into a concrete composite slab through a concrete curing layer, and the upper end of the steel bar truss extends out of the upper end face of the concrete curing layer. Thesteel bar truss prestressed concrete composite slab has the advantages that the structure is simple, integrity is good, strength is high, the rigidity of the space structure is far higher than that ofa common steel bar truss and the like.
本发明涉及装配式建筑楼板技术领域，具体地说是一种钢筋桁架预应力混凝土叠合板及制作方法，其特征在于该叠合板包括纵向预应力筋、横向热轧带肋钢筋、钢筋桁架、混凝土固化层，横向热轧带肋钢筋的上方并排设有与横向热轧带肋钢筋水平方向垂直连接的纵向预应力筋，纵向预应力筋和横向热轧带肋钢筋连接后呈网格状平面，网格状平面上方设有钢筋桁架，钢筋桁架包括上弦筋、加强弦筋、下弦筋和波浪形格构筋，纵向预应力筋、横向热轧带肋钢筋、钢筋桁架相互连接后经混凝土固化层固化成混凝土叠合板，所述的钢筋桁架的上端伸出混凝土固化层上端面，具有结构简单、整体性好、强度高、空间结构的刚度远超普通钢筋桁架等优点。
