Wall hanger for nuclear power plant and construction method thereof

Abstract

The invention discloses a nuclear power plant wall hanger comprising at least one unit support. Each unit support is an H-shaped frame composed of a bottom support rod extensible and adjustable in length, a top support rod extensible and adjustable in length and a connecting rod jointly; each connecting rod is connected between each bottom support rod and the corresponding top support rod and capable of adjusting the height interval between the bottom support rod and the top support rod in an extensible manner; each unit support is provided with two fixed locking pieces, the rear end of the bottom support rod and the rear end of the top support rod of each unit support are inserted into the corresponding fixed locking pieces to be locked and fixed on a wall, the front ends of the top support rods between the adjacent unit supports are connected with a cross bar, and the cross bar is capable of adjusting the transverse interval between the two unit supports in an extensible manner. Welding is omitted, abutting joint between equipment and the wall can be realized smoothly, on-site workload is reduced effectively, working efficiency is improved, and strength of embedded parts is guaranteed.

Description

technical field [0001] The invention relates to the technical field of installation and construction of nuclear power plant equipment, in particular to a wall hanger for a nuclear power plant and a construction method thereof. Background technique [0002] In order to improve the convenience and quickness of equipment installation and disassembly, speed up the construction progress, and improve construction efficiency, a large number of embedded parts are usually embedded in the walls of nuclear power plants. The installation of nuclear power plant equipment requires high construction accuracy of the embedded parts of the wall. Even if one of the embedded parts does not meet the construction accuracy requirements, it may directly affect the normal installation of the equipment, cause rework, and slow down the construction progress of the entire project. Even downtime. However, at present, pre-embedding is usually used in construction, and the embedded parts and equipment ar...

Problems solved by technology

The installation of nuclear power plant equipment requires high construction accuracy of the embedded parts of the wall. Even if one of the embedded parts does not meet the construction accuracy requirements, it may directly affect the normal installation of the equipment, cause rework, and slow down the construction progress of the entire project. even downtime

However, at present, the pre-embedded method is usually used in construction, and the embedded parts and equipment are used for welding and fixing. The disadvantage of this method is that the positioning accuracy cannot be guaranteed, and the pre-embedded solidity is not good, and there is a risk of insufficient strength of the equipment base.

And this method also determines that a lot of welding work is required on site, so the construction operation environment is not good and the safety is relatively poor
