Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building for installing large equipment such as a tank or a torus indoors, and a construction process thereof.

Conventionally, this type of building is built by building a formwork outside the space where large equipment is planned to be installed.・By pouring concrete into the formwork, side walls are constructed and the building is completed. has been done.

However, with these conventional building construction methods, a certain amount of space is required for assembling and dismantling the formwork, making it difficult to construct side walls and install large equipment. Both projects could not be carried out at the same time, resulting in a delay in the entire construction project, and the play space between the building and large equipment became a problem.
1. It is an object of the present invention to provide a building for installing large equipment in which the play space can be reduced and construction work for side walls and installation work for large equipment can be carried out at the same time. Our goal is to provide construction methods that enable the construction of buildings.

The present invention is characterized in that a part of the formwork for constructing the side wall is made of a precast concrete plate.

The present invention will be described in detail below with reference to the drawings.

Figure 1 shows a building for installing large equipment according to the first embodiment of the present invention when a tank as a large equipment is installed indoors, and Figures 2 and 3 show a building for installing a boiling water nuclear power plant. This figure shows a large equipment installation building according to a second embodiment of the present invention in which a torus having a containment vessel for a power plant is installed indoors.

The side wall 1 of each building is a precast concrete board (hereinafter referred to as a PC board) 2 built vertically adjacent to the tank 11 and torus 12 side,
It is built vertically on the outside of this PC board 2, and the PC board 2
and the support member 3A, and the reinforced concrete construction area built around the outside of the PC board 2 and the steel column 3 (however,
In FIGS. 1 to 3, illustration of reinforcing bars is omitted. )
4. The steel columns 3 are supported by anchor bolts 5 installed in the foundation 10, and each column 3, 3
A steel beam 7 is bridged between the upper rooms.

A deck plate 8 is laid on the steel beam 7 to cover the space between each beam, and a reinforcing bar concrete construction section 9 (however, the reinforcing bar is not shown) is constructed on the deck plate. A ceiling wall 6 is formed by these steel beams 7, deck plates 8, and concrete construction part 9, and this ceiling wall 6 is continuously integrated and supported in a bridging state between the side walls 1, 1.

Although a part of the building is shown in FIG. 1, the building as a whole is surrounded by the side wall 1 and the ceiling wall 6 (however, the bottom floor of the lowest floor is surrounded by the foundation 10). ) The tank installation room is constructed dimensionally.

Similarly, although a part of the building is shown in FIGS. 2 and 3, this building as a whole consists of a torus installation room surrounded by the side wall 1, the ceiling wall 6, and the foundation 10. The upper floor is also formed to form any room. Note that the side wall 1 facing the inner periphery of the torus 12 is formed in an annular shape, therefore,
The PC board 2 in this annular side wall 1 is curved with an appropriate force curvature so as to fit the annular arc. In the figure, 12 people are vent pipes.

Next, an embodiment of the construction method for a building for installing large equipment according to the present invention will be described with reference to FIGS. 1 and 4 to 7 for the case of a building for installing a tank according to the above structure. explain.

First, as shown in FIG. 4, an appropriate number of steel columns 3 are erected vertically at predetermined locations on the foundation 10. The erecting location of each steel frame column 3 is located on the erecting line of the side wall where a chamber designed in advance corresponding to the size of the tank 11 to be installed is to be formed.

As shown in FIG. 5, a PC board 2 is attached to each steel column 3 so as to close the space between adjacent steel columns 3,
The plate 2 is supported by the steel column 3 via a support member 3A (not shown in FIG. 5). This PC board 2 is attached to the column surface of the steel frame column 3 on the side of the room where the roof is installed.

Next, reinforcing bars are placed on the back side of the PC board 2 (outside the room where the tank is installed). In order to simplify this reinforcement work, it is recommended to use the following reinforcement method.

As shown in FIGS. 5 to 7, the PC board 2
Horizontal reinforcing bars 21 are arranged and fixed on the back side of the frame via supporting bars □22. On the other hand, as shown in FIG. 8, vertical reinforcing bars 23 are arranged in a shelf shape and integrated in advance. After the PC board 2 is attached to the steel column 3 as described above, the vertical reinforcing bars 23 are attached to the horizontal reinforcing bars 21 so that both reinforcing bars form a grid.

Next, a formwork (not shown) is appropriately assembled on the back of the reinforcing bar grid, and concrete is poured between this formwork and the PC board 2.
Build reinforced concrete construction section 4. The reinforcing bars and steel columns are buried within this created portion 4.

In this way, the side wall 1 according to the above configuration is constructed. The installation work for the tank 11 indoors is carried out simultaneously with the above-mentioned elliptical work for the side wall 1. Tank 11
Even if the installation work of '(+','l) is carried out at the same time, the work to form the inner surface of wall 1 is only the attachment of P℃ board 2, so there is no need to assemble or remove the formwork as in the past. There is no complicated work involved, and the space required for this work is small, and there is no interference between the tank aBZ construction and the side wall construction work.Also, because the space is small, the tank can be completely filled in the room. can be installed, the amount of play space can be reduced as much as possible, and it is possible to expect savings in construction costs for the entire building and effective use of land.

After the construction of the side walls is completed, or at the same time, a steel beam is bridged between the steel columns, a deck plate is laid on the steel beam, a reinforced concrete construction section is created on the deck plate, h using an appropriate construction method, and the ceiling wall 1 is constructed. Build. Thereafter, the above-mentioned construction work is repeated to construct the building, and according to this embodiment, the installation work of the tank indoors can proceed at the same time as the construction work of the building, so the construction period can be shortened. can do.

Furthermore, since the extra space required for constructing the side walls can be suppressed, the generation of idle spaces can be suppressed.

Furthermore, since the ceiling wall was constructed using the deck plate construction method, shoring can be omitted, and the tank installation work can proceed smoothly at the same time without being obstructed by the shoring.

The building for installing the torus can also be constructed using the same construction method as the building for installing the tank.

As explained above, according to the present invention, a building for installing large equipment with a small play space can be obtained, and the installation work of large equipment inside the building can be carried out simultaneously with the construction work of the building. This allows the overall construction period to be shortened.
