Nuclear power plant composite floor slab module and construction method thereof

Abstract

The invention discloses a nuclear power plant composite floor slab module and a construction method of the nuclear power plant composite floor slab module. The construction method comprises the following steps that (1) steel structure floor slab parts are prefabricated; (2) professional items are installed on the steel structure floor slab parts, and then the composite floor slab module is acquired; (3) bracket parts for placing the composite floor slab module in position are installed on the side wall where site construction is finished; (4) the composite floor slab module is transported to a site and hoisted in position; (5) the composite floor slab module is connected with a surrounding civil engineering structure to construct, and the professional items are connected with a system. Compared with the prior art, according to the construction method of the nuclear power plant composite floor slab module, a region on a construction site where originally civil engineering is conducted and then installing construction is conducted is changed into the composite floor slab module, therefore, the effects that prefabrication of the composite floor slab module and the composite floor slab module is wholly introduced, located and then poured quickly on the site are achieved.

Description

technical field [0001] The invention belongs to the field of design and construction of nuclear power plants. More specifically, the invention relates to a composite floor module of a nuclear power plant and a construction method thereof. Background technique [0002] In nuclear power plants, there are usually some densely arranged and narrowly spaced areas, where many professional items such as pipes, cable trays and ventilation are installed on the upper floor of the area. In the traditional construction mode, the civil construction contractor usually carries out the construction of the civil structure first. After the concrete pouring of the upper floor in the area is completed, the interior decoration and cleaning of the room are carried out. After meeting the relevant requirements, it is handed over to the installation contractor for room construction. Installation and construction of various professional items. Therefore, these areas not only have a long construction ...

AI Technical Summary

Problems solved by technology

Therefore, these areas not only have a long construction period, but also are limited by the narrow space conditions on the site, requiring multiple types of cross-working operations, resulting in problems such as poor construction conditions, high construction safety and quality risks, and low work efficiency.
