Construction method of stainless steel cladding top plate of building water tank and building water tank

Abstract

The invention discloses a construction method of a stainless steel cladding top plate of a building water tank. The construction method comprises the following steps that S1, a prefabricated floor slab with a stainless steel cladding is prefabricated in a factory; S2, the prefabricated floor slab is installed on a bracket at the top of the water tank wall, a second stainless steel covering face is arranged at the top of the bracket, and a first stainless steel covering face and the second stainless steel covering face are connected in a sealed mode; and S3, a concrete overlapping layer is poured at the top of the prefabricated floor slab, so that the water tank top plate with the stainless steel covering face is formed. The invention further discloses the building water tank. Construction is convenient, the construction workload is small, the cost is low, and the construction quality is guaranteed.

Description

technical field [0001] The invention specifically relates to a construction method of a stainless steel cladding top plate of a structure water tank and the structure water tank. Background technique [0002] According to the design requirements of the nuclear power plant, there are various water tanks for different purposes inside the nuclear power plant. In order to prevent the liquid inside the water tank from leaking to the wall and the ground, it is necessary to lay a layer of stainless steel cladding on the inside of the water tank to form a good seal and acid and alkali resistance. Corroded isolation barrier. [0003] At present, the construction methods of stainless steel cladding are mainly divided into two types: post-pasting method and first-pasting method. Among them, the post-pasting method is to weld and assemble the stainless steel cladding on the concrete structure after the concrete structure of the water tank is completed; and the first posting method The ...

Problems solved by technology

[0004] (1) Compared with the post-paste method, the first-paste method significantly saves the construction period. However, when the first-paste method is used for the construction of the water tank roof, the formwork and support system for the construction of the water tank roof are first erected, and the prefabricated The stainless steel cladding module is hoisted in place, and then the roof concrete is poured. After the concrete strength meets the requirements, the formwork and support system are removed, and the water tank is generally a closed water tank. After the roof is poured, the formwork and support system inside the tank cannot be used. To take it out, it is necessary to leave a construction hole on the water tank for removing the formwork and support system. After the formwork and support system are removed, the construction hole will be poured again, and the local area of ​​the secondary pouring will be filled by the post-fixing method. Stainless steel cladding, which not only makes on-site construction complicated, but also difficult to control the quality of the secondary pouring and the weld quality of the post-paste method to complete the stainless steel cladding

[0005] (2) The roof cladding of the water tank and the wall cladding are connected by on-site welding. The weld seam is located on the top of the water tank, which requires welders to perform overhead welding operations. Overhead welding requires high technical requirements for welders, and the operation is difficult and prone to welding defects. The argon gas generated during welding work in a closed water tank is not easy to diffuse, which has a great impact on human health
