Steel strand anchor installation device and its connecting parts

Abstract

The invention discloses a steel strand anchor installation device and its connecting parts. The connecting part includes H-shaped steel B. The left end surface of the H-shaped steel B is a cross-section and is welded and fixed with a connecting plate. There are bolt holes B around the anchorage opening, the right end surface of H-shaped steel B is a cross-section and is welded and fixed with a connecting flange C, and the left side of the web of H-shaped steel B is recessed to accommodate The anchorage of the anchorage is slotted, and a plurality of connection holes C are respectively opened on the front and rear side flanges of the H-shaped steel B. The technical scheme is convenient to disassemble and assemble, and can be reused many times to achieve the purpose of saving construction cost and facilitating construction.

Description

technical field [0001] The invention relates to a steel strand anchor installation device of an internal support system for foundation pit support, in particular to a connecting part of the steel strand anchor installation device. 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 ...

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

[0003] At present, after the foundation pit support is completed, there is no prestress application process, or adding supports, which cannot further improve the overall stiffness of the support system after the support system is assembled.
