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

Abstract

The invention discloses a fish-belly sill component of an inner supporting system for retaining and protection of a foundation pit. The fish-belly sill component of the inner supporting system for the retaining and the protection of the foundation pit comprises a bottom chord beam component made of H-type steel, a web member component, first inclined supporting components and second inclined supporting components. According to the bottom chord beam component, flange plates are fixed at the two ends of the bottom chord beam component, reinforcing plates, lifting lug plates and water drain holes are arranged in grooves in the two sides of the bottom chord beam component, and connecting holes are formed in a wing plate on the outer side of the bottom chord beam component; according to the first inclined supporting components and the second inclined supporting components, the two end faces of the first inclined supporting components and the two end faces of the second inclined supporting components are 45-degree diagonal planes and are welded with flange plates, one end of each inclined supporting component is in bolt connection with the web member component, the other end of each inclined supporting component is in bolt connection with the bottom chord beam component, lifting lug plates and water drain holes are arranged in the grooves in the two sides of each inclined supporting member, the two first supporting components are symmetrically arranged on the two sides of the web member component, and the two second inclined supporting components are symmetrically arranged on the two sides of the web member component; the bottom chord beam component, the web member component, the web plates of the H-type steel of the first inclined supporting components and the web plates of the H-type steel of the second inclined supporting components are located in the same plane. According to the technical scheme, the fish-belly sill component of the inner supporting system for the retaining and the protection of the foundation pit is convenient to disassemble and assemble and capable of being used repeatedly for multiple times, and achieves the purposes of saving construction cost and facilitating construction.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a fish-belly beam component 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 ...
