The supporting transfer part of the internal support system of the foundation pit support

Abstract

The invention discloses an opposite-supporting transit component for an internal supporting system for foundation pit supporting. The opposite-supporting transit component comprises a bottom side component, a first right-angle side component, a second right-angle side component, a bottom side supporting member, a first right-angle side supporting member and a second right-angle side supporting member which are made from H-shaped steel, wherein the bottom side component, the first right-angle side component and the second right-angle side component enclose an isosceles right-angle triangle and are fixedly arranged through welding, the three sides of the isosceles right-angle triangle are strengthened through the vertical bottom side supporting member, the first right-angle side supporting member and the second right-angle side supporting member, a plurality of connecting holes are respectively formed in wing plates at the outer sides of the bottom side component, the first right-angle side component and the second right-angle side component, flange plates are respectively arranged at the three angles of the triangle, and draining holes are formed in a web plate of the H-shaped steel of each component. The opposite-supporting transit component is convenient to dismount and mount and can be repeatedly reused, so that the aims of reducing the construction cost and facilitating construction are reached.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a supporting transfer part of an internal support system for foundation pit support. Background technique [0002] In soft soil deep foundation pit engineering, reinforced concrete or steel pipe supports the support structure. In order to reduce the deformation of the foundation pit and increase the stability, the commonly used methods are: increase the size of the reinforced concrete purlin street surface, increase the number of steel pipe supports, Reduce spacing etc. But this will greatly increase the consumption of building materials and also reduce the effective construction space in the foundation pit. Since the steel support structure currently used mainly uses a single section steel or steel pipe as a support beam, there is no effective connection between each section steel or steel pipe, and it cannot work as a composite structure, so their support stiffness i...

AI Technical Summary

Problems solved by technology

Since the steel support structure currently used mainly uses a single section steel or steel pipe as a support beam, there is no effective connection between each section steel or steel pipe, and it cannot work as a composite structure, so their support stiffness is relatively low. The force it can withstand is relatively limited. For foundation pits with large spans, it is difficult to control their deformation with the current steel support support

Because many of these supports are made according to the requirements of on-site construction, there is no standardized connection size, and the purpose of interchangeability and universal use between various parts cannot be achieved. After the foundation pit construction is completed, most of the support parts have become disposable consumables. , cannot be reused
