一种用于基坑围护结构的可拼接钢支撑连接件
摘要：
一种用于基坑围护结构的可拼接钢支撑连接件，属于基坑工程技术领域。钢支撑标准段在工厂预制时，将钢支撑两端头做成榫头和榫槽的形式，在施工现场，将两节钢支撑榫头端和榫槽端拼接成整体，以限制其水平位移，再利用套筒由钢支撑一端滑动至接头处，固定榫头和榫槽，以限制其竖向位移。本实用新型通过改进钢支撑端头构造，利用榫卯连接方式，便于施工现场拆卸和安装，以减少钢支撑现场拼装时间，有利于提高施工效率。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses a splicable steel support connecting piece for a foundation pit support structure, and belongs to the technical field of foundation pit engineering. When the steel supportstandard section is prefabricated in a factory, the two ends of the steel support are made into a tenon and a mortise, the tenon ends and the mortise ends of the two sections of steel supports are spliced into a whole to limit the horizontal displacement of the steel support standard section, and then the sleeve is used for sliding to the joint from one end of the steel support to fix the tenon and the mortise so as to limit the vertical displacement of the steel support standard section. By improving the end structure of the steel support and utilizing a mortise and tenon joint mode, the steel support is convenient to disassemble and assemble on a construction site, so that the on-site assembly time of the steel support is shortened, and the construction efficiency is improved.
