Prefabricated inner support edge node structure of foundation pit and construction method
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to a prefabricated inner support edge node structure of a foundation pit and a construction method. The prefabricated inner support edge node structure comprises a prefabricated support and a top beam or a waist beam, wherein a first telescopic joint is fixed to the end of the prefabricated support, and a second telescopic joint is fixed to the inner side of the top beam or the waist beam; the first telescopic joint and the second telescopic joint are of the same structure and eachcomprise a solid steel plate, a U-shaped hole steel plate, a U-shaped steel plate and a stiffening plate; one end of the U-shaped steel plate penetrates through a U-shaped hole in the U-shaped hole steel plate and is welded to the solid steel plate, and multiple lines of long circular holes are formed in two side walls of the other end of the U-shaped steel plate; the solid steel plate is connected with the U-shaped hole steel plate through the stiffening plate; and the U-shaped steel plate of the first telescopic joint is clamped in the U-shaped steel plate of the second telescopic joint, andthe long circular hole in the first telescopic joint is connected with the long circular hole in the second telescopic joint through a bolt. According to the prefabricated inner support edge node structure, the requirements of rigid connection and equal-strength connection of side nodes can be met, the engineering safety is guaranteed, additionally, the length of the joints can be adjusted, and the construction error can be adjusted.
本发明属于地下基坑工程技术领域，具体涉及一种装配式基坑内支撑边节点结构及施工方法，包括装配式支撑以及冠梁或腰梁；装配式支撑的端部固定有第一伸缩接头，冠梁或腰梁的内侧固定有第二伸缩接头；第一伸缩接头和第二伸缩接头的结构相同，均包括实心钢板、U孔钢板、U形钢板和加劲板；U形钢板的一端贯穿U孔钢板上的U形孔并与实心钢板焊接，另一端的两侧壁上设有多列长圆孔；实心钢板与U孔钢板通过加劲板连接；第一伸缩接头的U形钢板卡在第二伸缩接头的U形钢板中，且第一伸缩接头上的长圆孔与第二伸缩接头上的长圆孔通过螺栓连接。本发明既能满足边节点的刚性连接、等强连接的需要，保证工程安全，同时又能调节接头的长度，调整施工误差。
