Large-span prestressed steel reinforced concrete combined floor support plate and construction method
The invention discloses a large-span prestressed steel reinforced concrete combined floor support plate and a construction method, and belongs to the technical field of building construction.The large-span prestressed steel reinforced concrete combined floor support plate comprises a floor support plate body arranged between two adjacent section steel beams, and the floor support plate body comprises a plurality of bottom dies laid in the length direction of the section steel beams and auxiliary beams vertically installed in the middles of the bottom dies; the distribution steel bars are arranged between the adjacent auxiliary beams, the load-bearing steel bars are located above the distribution steel bars, a pair of prestressed steel bars are arranged on the two sides of each auxiliary beam, and a plurality of reinforcing steel bars are arranged above the section steel beam. The structure of an existing floor support plate is improved, the auxiliary beams are used for supporting in cooperation with the structure, meanwhile, the distributed steel bars and the stressed steel bars are matched to increase the strength, the prestressed steel bars are arranged, tensioning is conducted after concrete reaches a certain strength, and therefore the purposes of increasing the bearing capacity and reducing deflection and cracks are achieved; the span of the steel reinforced concrete composite floor support plate can reach 3-4m, the steel consumption is reduced, and the cost is saved.
本发明公开了一种大跨度预应力型钢混凝土组合楼承板及施工方法，属于建筑施工技术领域，包括设置于相邻两个型钢梁之间上的楼承板体，所述楼承板体包括沿型钢梁长度方向铺设的多个底模，垂直安装在底模中部的辅助梁，设置于相邻辅助梁之间的分布钢筋，以及位于分布钢筋上方的若干受力钢筋，所述辅助梁的两侧设有一对预应力钢筋，所述型钢梁的上方设有多个加强钢筋。本发明通过对现有的楼承板的结构进行改进，利用辅助梁的结构配合支撑，同时配合分布钢筋、受力钢筋增加强度，并设置预应力钢筋，在混凝土达到一定强度后张拉，以达到增加承载力、减小挠度和裂缝的目的，使得型钢混凝土组合楼承板能够达到3～4m的跨度，减少钢材用量，节约成本。
