穿越支承型防震缝节点构造施工技术

Construction Technology of Through-supported Anti-seismic Joints

根据2栋建筑在平面上有较多区域重合时,如何实现重叠区域边界节点连接展开分析讨论,通常方式下,切直缝脱开与强连接均有较明显缺点,最终研究得出穿越支承型防震缝节点构造法,分别从技术特点、适用范围、技术原理、施工工艺等方面进行阐述。采用该施工技术既能消除地震作用下2栋建筑间相互传递水平剪力及局部碰撞导致的结构抗震影响,又能为被穿越结构在支座节点处提供竖向支承。

Based on when two buildings have some overlapping areas on the plane,how to achieve the boundary joints connection of their overlapping areas,this paper analyzes and discusses the shortcomings of straight seam separation and strong connection in the usual way.Finally,the construction method of the joint-supported anti-seismic joint is obtained,and the technical characteristics,scope of application,the technical principle,construction technology and other aspects are described.The construction technology can not only eliminate the adverse seismic effects caused by the horizontal shear force and local collision between the two buildings under the earthquake,but also the vertical support for the traversed structure at the support joints is provided.
