Fabricated operation platform for tensioning deep foundation pit anchor cable

Abstract

The invention discloses a fabricated operation platform for tensioning a deep foundation pit anchor cable. The operation platform comprises a support seat steel connecting rod, a diagonal draw bar, a steel upright rod, a platform rod, a handrail upright post insertion pipe, a handrail upright post, a handrail grab rail insertion pipe, a longitudinal grab rail and a support seat steel plate, wherein the diagonal draw bar, the steel upright rod and the platform rod are connected to form a triangle, and connected with a reinforcing steel plate and the support seat steel connecting rod through a member node; the support seat steel connecting rod is connected with the support seat steel plate; the support seat steel plate is connected with a crown beam or a waist beam of the deep foundation pit anchor cable through embedded bolts; the handrail upright post insertion pipe is fixed at the end part of the platform rod; a handrail upright post shaft is inserted and fixed into the handrail upright post insertion pipe; the handrail grab rail insertion pipe is arranged on the side wall of the handrail upright post; a longitudinal grab rail shaft is inserted into the handrail upright post insertion pipe to form one single-frame bracket; and a bamboo plywood and a transverse grab rail of the platform are arranged between adjacent single-frame brackets. The fabricated operation platform can be dismantled and assembled, is good in overall stability, safe, reliable, green and environment-friendly, and can be widely applied to tensioning operation of the deep foundation pit anchor cable of a large building, and the construction period is shortened.

Description

technical field [0001] The invention relates to an assembled operating platform, in particular to an operating platform used for tensioning anchor cables in deep foundation pits of large buildings. Background technique [0002] In the construction stage of the basement excavation project of a large building, the support project is usually involved, and the support anchor cable is a relatively common structural treatment measure used in the support project. According to the construction process and technical requirements, the foundation pit soil will be excavated to varying degrees before the anchor cable is tensioned, which will cause the anchor cable grouting strength to meet the design requirements and then a temporary operating platform must be erected. The usual practice at the construction site is to use mobile door-type movable scaffolding or fastener-type scaffolding, which requires compaction and leveling of the site beside the foundation pit to ensure the safety and...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that it is necessary to set up a mobile door-type movable scaffold or a fastener-type scaffolding tube scaffold as an operation platform when the anchor cables of the deep foundation pit support in the existing engineering field are stretched, which has poor safety and stability and time-consuming With defects such as labor consumption, high construction cost, and inability to carry out cross-operation of foundation pit earthwork excavation, it provides a convenient material selection, convenient installation, low manufacturing cost, detachable assembly, good overall stability, safety and reliability, green environmental protection, and economical construction.
