解决钢筋混凝土无梁楼盖柱顶冲切问题的常用方法有 :增加板厚、提高混凝土强度、加大柱的截面 (设置柱帽 )、配置箍筋或弯起钢筋。这些方法或增加成本 ,或增加施工难度 ,具有一定的缺陷。在此 ,介绍了上海新国际博览中心工程采用双头锚提高楼盖 (板 )抗冲切能力的方法。该方法成本低 ,施工可操作性强 Common methods to solve the problem of punching the top of reinforced concrete beamless roof include: increase the thickness, increase the strength of concrete, increase the cross-section of the column (set the column cap), stirrup stirrup or bend steel. These methods or increase the cost, or increase the difficulty of construction, has some defects. Here, this paper introduces the method of using double-headed anchors to improve the punching ability of building (board) in Shanghai New International Expo Center.
