叠层橡胶隔震支座与钢筋混凝土结构或钢结构的连接非常简单而成熟,但与型钢混凝土(SRC)结构的连接非常复杂,现有资料中找不到做法。对叠层橡胶隔震支座与SRC柱脚的连接进行了研究,发现柱底预埋件的锚筋与SRC柱主筋及型钢柱底板冲突,导致叠层橡胶隔震支座与SRC柱连接困难,提出将柱主筋通过套筒与预埋钢板焊接取代锚筋,将型钢柱底板通过螺栓与预埋钢板连接,从而解决预埋件锚筋、柱主筋、型钢柱底板相互冲突的问题,然后遵循规范提出预埋钢板、锚筋、钢柱底板及连接螺栓的计算方法,并将此项连接应用于云南省博物馆新馆项目,解决了该工程中叠层橡胶隔震支座与SRC柱脚的连接问题。
Laminated rubber bearings and reinforced concrete or steel structure of the connection is very simple and mature, but the connection with the SRC structure is very complicated, the existing information can not be found. The connection between the laminated rubber bearing and the SRC column was studied. It was found that the anchor bars of the embedded part at the bottom of the column collided with the SRC column and the bottom plate of the steel column, which made it difficult to connect the laminated rubber bearing with the SRC column Proposed to replace the anchor bars by welding the sleeve with the embedded steel plate, and to connect the steel plate base plate with the embedded steel plate by bolts to solve the problem of the mutual interference of the embedded bars, the anchor bars and the steel plate base floor, and then follow This paper puts forward the calculation method of embedded steel plate, anchor bar, steel floor plate and connecting bolt, and applies this connection to the new museum project in Yunnan Province to solve the problem that laminated rubber bearing and SRC column foot Connection problems.
