Novel vertical distribution steel bar non-connection assembly type profile steel shear wall and construction method
The invention provides a novel vertically-distributed steel bar non-connection assembly type profile steel shear wall. The novel vertically-distributed steel bar non-connection assembly type profile steel shear wall comprises a middle wall plate, edge components and bottom supporting units. Second closed stirrups are arranged at the two ends in the middle wall plate in the wall height direction, and the outer side of the profile steel is sleeved with first closed stirrups. The construction method comprises the following steps of arranging the cushion blocks, laying the bedding layer, hoisting the middle wall plate, connecting the main reinforcements with the profile steel and pouring concrete. The structural steel is arranged on the edge component, so that the defect that the bending bearing capacity of the wall body and the shearing bearing capacity of a horizontal joint are poor due to the fact that vertically-distributed steel bars in net-shaped steel bars of the middle wall plate are disconnected at the floor connecting position can be effectively overcome; meanwhile, the problems that the construction cost is high, steel bars are difficult to place in place and the grouting quality is difficult when an integral shear wall structure is assembled can be avoided; the actual construction site workload is greatly reduced in the mode that concrete is poured on the edge components on site, and the wall plate of the middle wall plate and the second closed stirrups are integrally prefabricated.
本发明提供了一种新型竖向分布钢筋不连接装配式型钢剪力墙，包括中部墙板、边缘构件和底部支撑单元；中部墙板内两端沿墙高方向设有第二封闭箍筋，型钢外侧套设有第一封闭箍筋；施工方法包括以下步骤：布置垫块、铺设坐浆层、吊装中部墙板、连接主筋与型钢和浇筑混凝土；本发明通过在边缘构件布置型钢可有效的弥补中部墙板网状钢筋内竖向分布钢筋在楼层连接处断开连接所导致的墙体抗弯承载力以及水平接缝抗剪承载力的缺失；同时可以规避装配整体式剪力墙结构所产生的建造成本高，钢筋就位难，以及灌浆质量难的问题；通过在边缘构件进行现场浇筑混凝土，中部墙板的墙板与第二封闭箍筋整体预制方式，极大地减少了实际施工现场工作量。
