Connecting structure of foundation pit steel support and foundation pit enclosure
The invention relates to a connecting structure of a foundation pit steel support and a foundation pit enclosure. The connecting structure comprises the foundation pit steel support. At least one embedded part is arranged in the foundation pit support; one end of the adjustable head is connected with the embedded part, and the other end of the adjustable head is provided with a limiting part; one side of the supporting end is connected with the foundation pit steel support, and the other side of the supporting end is provided with a sliding cavity in sliding fit with the movable head; a tensile matching part and a compression matching part are arranged in the sliding cavity, the compression matching part is arranged close to the foundation pit steel support, and the tensile matching part is arranged far away from the foundation pit steel support; and at least one wedge block. The adjustable head is connected in the sliding cavity of the supporting end in a sliding mode, after prestress is applied to abut against the foundation pit steel support and the foundation pit enclosure, the gap between the tensile matching part and the limiting part is filled with the wedge block, and then the foundation pit steel support has the tensile effect. The use scene of the foundation pit steel support is expanded, the structure of the foundation pit steel support does not need to be changed, operation is easy, and construction is convenient.
本发明涉及一种基坑钢支撑与基坑围护的连接结构，包括：基坑钢支撑。基坑围护，基坑围护中设有至少一预埋件；至少一活络头，活络头的一端连接预埋件，另一端设有限位部；支撑端头，支撑端头的一侧连接基坑钢支撑，另一侧设有与活络头滑动配合的滑腔；滑腔中设有抗拉配合部和抗压配合部，抗压配合部靠近基坑钢支撑设置，抗拉配合部远离基坑钢支撑设置；至少一楔块。活络头滑动连接在支撑端头的滑腔中，在施加预应力顶紧基坑钢支撑和基坑围护后，在抗拉配合部和限位部之间的空隙中填充楔块，即可使得基坑钢支撑具有抗拉的效果。本发明拓展了基坑钢支撑的使用场景，而且不需要改变基坑钢支撑的结构，操作简单，便于施工。
