The invention relates to the field of building construction, in particular to a foundation pit structure based on prestress. Comprising web members, anchor seats, tie bars, gusset plates, connecting pieces, main supports and multi-hinge joints. The brace is arranged between the two symmetrically-arranged anchor seats and fixed through connecting holes in the end plates of the anchor seats, and the tie bar comprises a bolt hole and a first sliding groove. The gusset plate comprises a bolt and a bolt hole; the connecting piece comprises a rib plate and a bearing plate; the gusset plate is connected to the first sliding groove of the tie bar in a sliding mode in the direction of the tie bar; the first sliding groove is formed in the side face of the tie bar. The bottom of the bearing plate is connected with the gusset plate through a fixed hinge, the vertical movement of the tie bar can drive the bearing plate to rotate by a certain angle, and whether the angle of the fixed hinge is limited or not is determined by whether the fixed hinge at the bottom is loosened or not; the tie bar can vertically move through the first sliding groove, is convenient and fast and does not need to be detached, and therefore the main supporting component is more convenient and efficient to install.
本发明涉及建筑施工领域，特别涉及一种基于预应力的基坑结构；包括腹杆、锚座、系杆、节点板、连接件、主撑和多铰节点；所述拉条设置于两个对称设置的锚座之间，通过所述锚座的所述端板上的连接孔固定，所述系杆包括螺栓孔、第一滑槽；所述节点板包括螺栓、螺栓孔；所述连接件包括筋板、承压板；在系杆方向上所述节点板滑动连接在所述系杆的第一滑槽；所述第一滑槽开在系杆的侧面；所述承压板底部与所述节点板通过固定铰链相连，系杆的垂直移动可以带动承压板转动一定的角度，而底部的固定铰链松紧与否决定其角度的限位与否；系杆可以通过第一滑槽垂直移动，方便快捷，不必将其拆卸，使得在安装主撑构件时，更加方便高效。
