背栓式干挂石材幕墙连接方式是在石材背面钻燕尾孔,与凸形胀栓结合,然后与龙骨连接,龙骨由金属支架组成,通过埋件连接固定在外墙上。背栓式干挂石材幕墙是近几年从国外引进的一项新技术,在外观、安全性、耐久性、可更换性等方面具有较大的优势,它可不受主体结构较大位移或温差的影响,不会在板材内部产生附加应力,从而控制了破坏状态,特别适用于高层建筑和抗震建筑幕墙。在施工过 Back bolt dry hanging stone curtain wall connection is done on the back of the stone drill dovetail hole, combined with the convex expansion bolt, and then connected with the keel, keel composed of metal brackets, embedded parts connected by the external wall. Back bolt dry hanging stone curtain wall is introduced from abroad in recent years, a new technology in the appearance, safety, durability, interchangeability, etc. has a greater advantage, it can be subject to the main structure of the larger displacement or temperature difference Of the impact, will not produce additional stress within the plate, thereby controlling the destruction of state, especially for high-rise buildings and curtain wall construction.
