Steel stranded wire anchor gear installing device for foundation pit supporting inner supporting system

Abstract

The invention discloses a steel stranded wire anchor gear installing device for a foundation pit supporting inner supporting system. The steel stranded wire anchor gear installing device comprises an anchor gear seat and connecting components, wherein the anchor gear seat comprises H sectional steel A, a flange A is welded and connected at the left side, an anchor gear base plate is welded at the right end surface, the anchor gear base plate is provided with an anchor gear installing hole, two long wire passing holes, three baffle plates, one connecting flange B and a plurality of connecting holes A are arranged on a front side wing plate, a plurality of connecting holes B are formed in a back side wing plate of the H sectional steel A, two guide separation plates are respectively arranged in grooves arranged at the two sides of the H sectional steel A, guide holes are formed in the guide separation plates, two arc-shaped guide plates are arranged between the two guide separation plates, arc-shaped passages allowing steel stranded wires to pass are formed between the guide holes and the two arc-shaped guide plates, the connecting components comprise H sectional steel B, a connecting plate is welded at the left end surface, a flange C is welded and connected at the right side, an anchor gear open hole is formed in the center of the connecting plate, and the connecting plate is connected and fixed with the anchor gear base plate. The steel stranded wire anchor gear installing device adopting the technical scheme has the advantages that the dismounting and the mounting are convenient, the steel stranded wire anchor gear installing device can be repeatedly utilized for several times, and the goals of construction cost saving and convenient construction are reached.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a steel strand anchor installation device for an inner support system of 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...

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.
