Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for constructing a building of a power plant including a steel concrete structure,
Particularly, the present invention relates to improvement of a power plant construction method in which a modular structure in which a steel aggregate and building equipment are integrated is applied to a steel concrete structure part.

[0002]

2. Description of the Related Art Conventionally, a building of a nuclear power plant, for example, a reactor building or a turbine building, has a reinforced concrete structure or a reinforced concrete structure with built-in permanent or temporary steel. When constructing a building with such a conventional structure, for example, rebar and formwork work is performed after installing main or temporary steel frames, or concrete is placed after direct rebar and formwork work. Then, with the steps such as removing the formwork after the specified concrete strength is obtained, the floor of the building,
Building construction is proceeding from the bottom floor to the upper floor in the order of walls and ceiling.

[0003] Further, at the stage where the concrete, such as floors, pillars, walls, etc., of the construction work is completed and the required strength of the concrete is obtained, the area is once handed over to the mechanical side, and the pipes and equipment installed in the building. The construction of equipment such as supporting structures and other equipment that constitutes the plant will be performed. In the handed over area, after the mechatronics side has carried in equipment, members such as a pipe operation stand or prefabricated structures in advance, the area is handed over to the building side again for ceiling construction. On the building side, deck receiving beams, deck plates, etc. will be installed on the ceiling, and ceiling concrete will be placed. Then, when the required strength of the concrete is obtained, the area is handed over to the machine side again, and the machine side installs the equipment, pipes, operation platform, support structure and the like.

[0004] For the mounting of the operation pedestal and the supporting structure for the mechanics side work, embedded metal fittings preliminarily embedded in the floor, pillars, beams, walls, ceiling, etc. are used to join the building members.
FIG. 9 illustrates the conventional method. As shown in FIG. 9, the steel frame columns 2 are mounted on the building foundation 1 and the like, and the steel frame beams 3 are connected to the steel frame columns 2. Reinforcing bars 4 are arranged around the steel columns 2 and the steel beams 3, and concrete 5 is placed therein. In such a building structure of a steel-framed reinforced concrete structure, a plurality of rod-shaped support members 6 are provided inside.
Are vertically and horizontally arranged, and the supporting member 6 supports the building equipment 7 such as piping. The end of each support member 6 is
It is embedded in and supported by the concrete 5 via the embedded hardware 8.

With such a construction, conventionally, in the completed building or area after completion of the concrete pouring of the building, the pillars, beams (ceiling), floor concrete, etc. come into contact with the inner surface of the form, The support member 6 was connected to the embedded metal article 8 that was buried so that would appear on the concrete surface, and the building equipment 7 for plant construction was installed. After receiving the delivery of the completed building or area, the electric machinery side started construction.

Therefore, in the conventional nuclear power plant construction method, construction work in the same area is
Mechanical and electrical work was alternately carried in, which caused redundancy in the construction period.

Based on the conventional construction method, as a method for shortening the construction period, by adopting a large-scale temporary lifting machine, etc., the construction members are made larger by installing prefabricated reinforcing bars, prefabricated steel frames, etc. This has been dealt with by reducing the amount of construction work at the site. Similarly, in mechanical and electrical work as well, efforts have been made to increase the size of the installation members by lengthening the pipes, prefabricating the pipes and supporting members into one body, and reducing the amount of work at the installation site.

In recent planned plants, the demand for shortening the construction period has become stronger, and it has become necessary to develop a new construction method. As a method of solving such a requirement and further shortening the construction period, a module construction method in which a building member and a plant constituent device are integrated is known (Japanese Patent Laid-Open No. 10-
266602). According to this construction method, the steel pillars installed at the construction site of the plant building, the ceiling beams, the interior equipment installed at the construction site and the wall material of the side wall of the construction site are integrated to form a modular structure. We are trying to shorten the construction period by adopting a construction method in which this modular structure is assembled in a factory and then transported to the site and installed.

[0009]

However, in the construction method using the conventional module structure described above, when considering a large-scale module construction method of a power plant aiming at shortening the construction period, the wall material is larger than the size. Insufficient strength is expected due to the wall material, and the load on the wall surface is small due to the thin iron plate of the wall material, making it difficult to preliminarily mount large-load equipment and supporting structures as a module structure using the wall surface. it is conceivable that.

Further, since the wall surface is used as a module constituent element in advance, its use is limited, and it is difficult to easily deal with the change of the column arrangement and the like.

Further, since the construction equipment is supported only on the ceiling portion, only a limited range of equipment facilities such as piping, cable trays and ducts which can be installed on the ceiling portion can be installed. It is difficult to cope with an increase in the size of the module structure and an increase in the weight when a large amount of equipment is integrated into the module structure, which may prevent a significant reduction in the construction period.

The present invention has been made in view of the above circumstances, and it is possible to improve the strength of the module structure and to cope with the increase in the size of the module and the increase in the weight of the module when a large amount of equipment is integrated. In addition to being easy, it can be implemented in various forms corresponding to various building structures such as with or without walls, and it is possible to modularize a large number of vertically arranged equipment and equipment, and workability such as assembling into the building and concrete placement It is an object of the present invention to provide a power plant construction method that can significantly improve the reliability of the strength of the completed building.
