Foundation pit steel pipe supporting node structure capable of bearing tension
The invention belongs to the technical field of underground structure engineering, and particularly relates to a foundation pit steel pipe supporting node structure capable of bearing tension, which comprises a pair of connecting blocks which are distributed up and down when in use; a pair of steel pipes is symmetrically arranged on the two sides of the connecting block; a connecting piece is arranged between the steel pipe and the connecting block; according to the foundation pit steel pipe supporting node structure capable of bearing the tension, a combined structure of the steel pipes and the connecting blocks is arranged to be arched, when the upper portion of the supporting structure is pulled through a rope, the arched combined structure of the steel pipes and the connecting blocks on the upper portion is not prone to bending deformation downwards, and the tensile strength of the supporting structure is improved. When downward force is applied to the upper portion of the steel pipe, the arched combined structure can decompose the borne vertical force into axial force, and the design principle is the same as that of an arch bridge. The tensile capacity of the steel pipe supporting structure is improved, the tensile force bearing capacity of the steel pipe connecting joint is enhanced, and meanwhile the overall stability is improved.
本发明属于地下结构工程技术领域，具体的说是一种可承受拉力的基坑钢管支撑节点结构，包括连接块，所述连接块设置有一对且在使用时成上下分布；所述连接块的两侧对称设置有一对钢管；所述钢管与连接块之间设置有连接件；本发明所述的一种可承受拉力的基坑钢管支撑节点结构，通过将钢管与连接块的组合结构设置成拱形，当通过绳索对支撑结构的上方进行牵拉时，上方设置成拱形的钢管与连接块组合结构不易发生向下的弯曲变形，在钢管上方受到向下的力时，拱形的组合结构会将承受的竖向力分解成轴向力，这与拱桥的设计原理相同；增加钢管支撑结构的抗拉能力，也就增强了钢管连接节点承受拉力的能力，同时提高整体稳定性。
