Reinforced structure used for concrete displacement of shear wall and construction method of reinforced structure

Abstract

The invention provides a reinforced structure used for concrete displacement of a shear wall and a construction method of the reinforced structure. The reinforced structure includes a newly poured concrete wall surface and a number of permanent steel stand columns, wherein the permanent steel stand columns are arranged in the newly poured concrete wall surface side by side at intervals; the two sides, parallel to the wall surface, of each permanent steel stand column are provided with reinforcing steel bar nets, and each permanent steel stand column includes a center steel column, a connection steel plate located at the upper end of the center steel column, a nut located at the upper end of the connection steel plate, and a screw rod; the top ends of the screw rods on the upper portions of the permanent steel stand columns are welded with upper steel plates, the bottom portions of the steel columns are welded with lower steel plates, the upper steel plates are fixed with upper floor slabs, and the lower steel plates are fixed with ground floor slabs; a horizontal support is arranged between every two adjacent steel columns so as to increase the stabilization of the permanent steel stand columns and prevent the lateral deformation of the steel stand columns. According to the reinforced structure and the construction method of the reinforced structure, the mode in which concrete is dismantled in sections and the permanent steel stand columns are built in the concrete is adopted, the normal construction of the upper structure is not affected, that is, the shear wall displacement and the upper structure construction are conducted at the same time, the progress of the whole project is ensured, and the whole construction period is not affected.

Description

technical field [0001] The invention belongs to the technical field of construction engineering reinforcement, and in particular relates to a reinforcement structure for concrete replacement of a shear wall and a construction method thereof. Background technique [0002] Shear wall is also called aseismic wall. At present, reinforced concrete shear wall structure has been widely used in high-rise buildings, and it is an important structure that mainly bears horizontal load and vertical load in the building. In construction engineering, it may be encountered that the bearing capacity of the existing building shear walls is insufficient and needs to be reinforced. Commonly used reinforcement methods include enlarging section reinforcement method, pasting steel plate reinforcement method, replacement concrete reinforcement method and so on. Enlarging the section reinforcement method will reduce the available space of the building; although the construction speed of the paste s...

AI Technical Summary

Problems solved by technology

Enlarging the section reinforcement method will reduce the available space of the building; although the construction speed of the pasted steel plate reinforcement method is fast, the ability of the pasted steel plate to work with the original wall is poor, which affects the reinforcement effect; although the replacement concrete reinforcement method can fundamentally Solve the problem of the original shear wall, but the common replacement method has high requirements for temporary support, and the existing method cannot achieve the simultaneous construction of the shear wall replacement and the superstructure, while affecting the construction period of the superstructure, construction safety It is also difficult to guarantee
