Construction method of arc-shaped outer wall of basement based on one-sided support formwork of stereotyped support

Abstract

The invention relates to a construction method for a basement arc-shaped outer wall based on a stereo-type bracket single side formwork. The construction method for the basement arc-shaped outer wallbased on the stereo-type bracket single side formwork is characterized in that anchor backing plates are preinstalled in a basement base plate, horizontal sliding grooves are formed in the lower portions of the anchor backing plates; a bracket base plate is arranged on the upper surface of the basement base plate, an arc-shaped formwork guide slot is formed in the position, corresponding to an outer wall internal mold, of the bracket base plate, a stand column is arranged on the upper surface of the basement base plate, a column top beam is arranged at the top of the stand column; a first hanging beam is connected with a second hanging beam through a hanging beam poisoning frame; a steel bar cage gripper is arranged at a cantilever end of the first hanging beam; a connecting protruding falcon and a connecting groove are formed in the joint position of an assembly type outer mold, a waterproof layer and a vertical-directional supporting rod are arranged on the outside of the assembly type outer mold; a protective layer control strip is arranged between the assembly type outer mold and an outer wall inner mold and a wall body steel bar cage; and an assembly type outer mold limiting groove and a supporting rod limiting groove are formed in the foundation of the wall bottom in a pre-installation mode. The construction method for the basement arc-shaped outer wall based on the stereo-type bracket unilateral mode branch not only can improve the construction efficiency of the arc-shaped outer wall and the formwork bracing quality, but also can reduce the difficulties of lifting and positioning of the wall body steel cage, and further can improve the use ratio of materials.

Description

technical field [0001] The invention relates to a construction method for an exterior wall of a basement, in particular to a method for constructing an arc-shaped exterior wall of a basement based on a single-side support formwork of a stereotyped bracket, which is convenient for hoisting of a steel cage, convenient for on-site installation, and accurate positioning of a formwork. It belongs to the field of construction engineering and is applicable to one-side Formwork basement curved exterior wall construction project. Background technique [0002] With the development of my country's economy, the spatial shape of building structures and basement structures has become more and more complex. During the on-site construction process, especially in the construction process of some basement exterior walls, problems such as difficulty in formwork support, low positioning accuracy of reinforcement cages, and unsatisfactory protective layer thickness are prone to occur.

AI Technical Summary

Problems solved by technology

This method is difficult to solve the problems of accurate positioning of the curved exterior wall formwork, rapid hoisting of the steel cage, and effective control of the thickness of the protective layer.
