Steel strand anchor installation device and anchor seat thereof

Abstract

The invention discloses a steel strand anchor installation device and an anchor seat thereof. The anchor seat comprises H-shaped steel A, wherein the left side of the H-shaped steel A is connected with a flange A in a welding way; an anchor base plate is welded on the right end face of the H-shaped steel A; an anchor installation hole is formed in the anchor base plate; two threading long holes, three baffle plates, one connecting flange B and multiple connecting holes A are formed/arranged on the front side flange plate; multiple connecting holes B are formed in the rear side flange plate of the H-shaped steel A; two guide clapboards are arranged in each of two side grooves in the H-shaped steel A; guide holes are formed in the guide clapboards; two arc-shaped guide plates are arranged between the two guide clapboards; an arc-shaped passage for the passing of steel strands is formed between the guide holes and the arc-shaped guide plates. The steel strand anchor installation device and the anchor seat thereof are convenient to assemble or disassemble and can be repeatedly utilized for multiple times; therefore, the purposes of saving construction cost and facilitating construction are realized.

Description

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

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.
