Punching-resistant reinforcing and post-tensioning device for flat slab
A unit assembly of the device comprises a horizontal steel plate, the two ends of the horizontal steel plate are end side edges respectively, and the inner end points of the end side edges extend into the horizontal steel plate to form notch side edges; the side edge of the notch of the horizontal steel plate extends downwards to form a first vertical steel plate, and the side edge of the end of the horizontal steel plate extends downwards to form a second vertical steel plate. The four unit assemblies surround the periphery of the structural column; the upper surface of the horizontal steel plate is attached to the floor system. The first vertical steel plate is connected with the structural column, so that the unit assembly is connected with the structural column; the adjacent second vertical steel plates of the adjacent unit assemblies are fixedly connected, so that the adjacent unit assemblies are connected; a post-tensioning anchor cable is arranged between every two adjacent structural columns, the two ends of each post-tensioning anchor cable are fixedly connected to the second vertical steel plates of the two unit assemblies correspondingly, and the post-tensioning anchor cables are anchored and restrained on the surfaces of the second vertical steel plates. The punching resistance of the whole structure is improved.
本发明提供一种无梁楼盖抗冲切加固及后张拉装置，所述装置的单元组件包括水平钢板，水平钢板的两端分别为端部侧边，端部侧边的内端点向水平钢板内延伸出缺口侧边；水平钢板的缺口侧边向下延伸出第一竖向钢板，水平钢板的端部侧边向下延伸出第二竖向钢板；4个单元组件围在结构柱的周边；水平钢板的上表面与楼盖贴合；第一竖向钢板与结构柱连接，而使单元组件与结构柱连接；相邻的单元组件的相邻的第二竖向钢板固定连接，而使相邻的单元组件连接；相邻的结构柱之间具有后张拉锚索，后张拉锚索的两端分别在两个单元组件的第二竖向钢板上固定连接，后张拉锚索在第二竖向钢板的表面进行锚固约束。本发明改善结构整体的抗冲切性能。
