Inner support system of cable-stayed space truss foundation pit
The invention discloses an inner support system of a cable-stayed space truss foundation pit. The inner support system comprises a steel strand, a stand column, web members, horizontal supports, an inclined support and a connecting piece, wherein the stand column is arranged on the upper part of the middle of the first horizontal support, the web members are installed between any two horizontal supports so as to form a space truss, the inclined support is supported between the lowermost horizontal support and a waist beam, and both ends of the steel strand are respectively anchored to the topof the stand column and a crown beam so as to form a cable-stayed space truss. According to the inner support system, the space truss is introduced into the inner support system of the foundation pit,the structural force transmission is clear, the overall rigidity is large, materials are saved, the deformation adjustability is achieved by adjusting the cable force of the steel strands, all components can be prefabricated into standard parts in a factory, all of the components can be installed mainly through bolt connection during site construction, the construction efficiency of a foundationpit support structure can be greatly improved, the construction quality is increased, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种斜拉式空间桁架基坑内支撑体系，包括钢绞线、立柱、腹杆、水平支撑、斜撑和连接件；所述的立柱设于第一道水平支撑中间上部，腹杆安装在任两道水平支撑之间，形成空间桁架，斜撑支于最下一道水平支撑与腰梁之间，钢绞线的两端分别锚固于立柱的顶部和冠梁处，形成斜拉式空间桁架。本发明将空间桁架引入基坑内支撑体系，结构传力明确，整体刚度大，用材省，通过调节钢绞线索力以实现变形可调，且各构件可在工厂预制成标准件，现场施工时各构件间主要通过螺栓连接即可完成安装，可大幅提高基坑支护结构的施工效率、提高施工质量、缩短工期、节约施工成本。
