Prestressed fish-bellied foundation pit steel support structure
The invention relates to the technical field of foundation pit supporting, in particular to a prestress fish-bellied foundation pit steel supporting structure which comprises a prestress fish-bellied beam, loading devices used for tensioning steel strands are arranged at the two ends of an upper chord of the prestress fish-bellied beam, and each loading device comprises a loading driving piece and a winding reel. An output shaft of the loading driving piece is coaxially and fixedly connected with the winding reel, the end of the steel strand penetrates through the winding reel and is connected with a fastening pin, the fastening pin abuts against the circumferential side wall of the winding reel, and the winding reel is used for winding the steel strand; and wire locking devices for clamping the steel strands are further arranged at the two ends of the upper chord of the prestressed fish-belly sill. The prestressed fish-belly sill has the effects that tension adjustment can be conveniently conducted on the steel strands, the construction progress is guaranteed, and the construction efficiency is improved.
本申请涉及基坑支护的技术领域，尤其是涉及预应力鱼腹式基坑钢支撑结构，其包括预应力鱼腹梁，所述预应力鱼腹梁的上弦杆两端均设有用以拉紧钢绞线的加载装置，加载装置包括加载驱动件和卷线筒，加载驱动件的输出轴与卷线筒同轴固接，钢绞线的端部贯穿卷线筒并连接有紧定销，紧定销与卷线筒的周向侧壁抵接，卷线筒用以卷绕钢绞线；预应力鱼腹梁的上弦杆两端还均设有用以卡紧钢绞线的锁线装置，本申请具有便于对钢绞线进行拉力调节，保证施工进度，提高施工效率的效果。
