Prestressed structure of concrete inclined strut
The prestressed structure of the concrete inclined strut is used for supporting a foundation pit and comprises an outer side enclosing purlin arranged on the side face of the foundation pit, the outer side enclosing purlin is provided with a supporting part connected with the side face of the foundation pit and a parallel part parallel to the side face of the foundation pit, and the parallel part is supported by the supporting part to form a supporting space; the side, away from the supporting part, of the parallel part is fixedly connected with the inclined strut. The inner side enclosing purlin is arranged in the supporting space and fixedly connected with the side face of the foundation pit; the prestress part is arranged between the outer side enclosing purlin and the inner side enclosing purlin and provides prestress for the inclined strut; prestress is applied to the inclined struts through the inner side enclosing purlins and the outer side enclosing purlins arranged on the side faces of the foundation pit and the ends of the inclined struts and the force transmission pieces between the inner side enclosing purlins and the outer side enclosing purlins, the supporting stability of the inclined struts is improved, and the safety of the foundation pit is improved.
本发明涉及一种混凝土斜撑的预应力结构，用于基坑的支撑，包括：设置于基坑侧面的外侧围檩，外侧围檩设有与基坑侧面连接的支撑部，以及与基坑侧面平行的平行部，支撑部将平行部撑起形成支撑空间，平行部远离支撑部的一侧与斜撑固定连接；设置于支撑空间内的内侧围檩，内侧围檩与基坑侧面固定连接；设置于外侧围檩和内侧围檩之间的预应力件，预应力件为斜撑提供预应力；通过设置于基坑侧面和斜撑端部的内侧围檩和外侧围檩，以及内侧围檩和外侧围檩之间的传力件，对斜撑施加预应力，提高斜撑支撑的稳定性，提高了基坑的安全性。
