Installation and construction method for large steel structure fixing foundation embedded parts

Abstract

The invention relates to an installation and construction method for large steel structure fixing foundation embedded parts. An embedded part installation device is used. The embedded part installation device comprises a base frame, a movable positioning unit and a clamping fixing unit. The base frame is of a concentric-square-shaped structure. A movable feeding unit is arranged at the lower end of the base frame. The clamping fixing unit is arranged on the inner wall of the lower end of the base frame. According to the method, the device replaces manpower to carry the embedded parts and position the embedded parts during pouring, so that the labor intensity of workers is reduced to a great extent. Through a multi-point fixing and clamping method, the problem that the whole embedded partscannot be effectively clamped when being clamped and fixed due to tiny errors is solved. By increasing friction between the device and the ground, stress displacement of the device during concrete pouring is prevented, and the problem that the embedded parts cannot be effectively fixed is solved.

Description

Technical field [0001] The invention relates to the technical field of steel structures, in particular to an installation and construction method of a large-scale steel structure fixed foundation embedded part. Background technique [0002] The pre-embedded parts are the components that are pre-installed and buried in the concealed project. They are the components placed during the pouring of the structure and used for the overlap of the superstructure. In order to facilitate the installation and fixation of the foundation of external engineering equipment, the foundation embedded parts are the basic components that connect the concrete structure and the steel structure. The steel structure that connects the steel structure and the foundation is a basic structure often used in construction projects. [0003] When pre-embedded parts are preset in construction projects, the following problems will be encountered: 1. Since the embedded parts are often very heavy, manual handling great...

AI Technical Summary

Problems solved by technology

[0003] The following problems will be encountered when presetting the embedded parts in the construction project: 1. Since the embedded parts are often very heavy, manual handling greatly increases the burden on the workers, and it is easy to cause injuries to the workers during the handling process. Question 2. However, since the embedded parts are not precision parts, there are slight errors between each embedded part. These slight errors will lead to the problem that the overall effective clamping cannot be carried out when the embedded parts are clamped and fixed; 3. The embedded parts are often connected to the foundation through concrete, so it is necessary to fix the embedded parts until the concrete is completely solidified. The movement of the embedded parts will cause problems such as voids after the concrete solidifies, and the embedded parts cannot be effectively fixed.
