DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building with a hardened roof, such as a nuclear power plant, a hall, or the like, which has a large space and carries predetermined objects.

[0002]

2. Description of the Related Art Conventionally, when constructing a concrete building, a temporary underwater roof, which is not affected by the weather, is provided on a building under construction for the purpose of wind protection, snow protection, cold protection, heat protection, etc. No. 6714, Japanese Patent Publication No. 2-626
No. 67, Japanese Patent Publication No. 2-26030, Japanese Unexamined Patent Publication No.
125840).

[0003] Particularly, in the construction of a nuclear power plant, large-scale construction such as a reactor building and a turbine building is performed for a long period of time, so that snow is accumulated in winter, such as in Hokkaido, the Tohoku region, and the Hokuriku region. In some areas, all-weather temporary roofs that are not affected by the weather are installed to reduce work efficiency in outdoor construction.

FIG. 11 is a view for explaining a method of building a nuclear power plant described in Japanese Patent Publication No. Hei 2-26030.
In FIG. 11, reference numeral 1 denotes a rock mass dug down. The bedrock 1 includes a foundation 3 and a steel frame 4 constituting a reactor building 2.
Has been built.

At a substantially central portion of the foundation 3, a containment vessel 5 is provided.
Is installed. A curing dome 6 is detachably mounted on the ceiling of the steel outer frame 4 located above the reactor containment vessel 5. A tower crane 7 is installed outside the steel frame 4.

According to this method of building a nuclear power plant, the curing dome 6 is installed on the ceiling of the reactor building 2 under construction. Can be cured.

After the foundation 3 is completed, the curing dome 6 is opened, and a pressure vessel or the like is carried into the reactor containment vessel 4 by a tower crane 7 installed outside the steel frame 4 to be constructed.

As described above, according to the method of building a nuclear power plant, it is possible to block wind and snow. FIG. 12 is a schematic view showing a state where the temporary structure described in Japanese Patent Publication No. 2-62667 is used for construction work of a reactor containment vessel.

In FIG. 12, reference numeral 10 denotes a steel frame.
A double air film structure roof 11 is installed on the upper part of the steel frame body 10. The double air film structure roof 11 is attached to an upper portion of the steel frame body 10 via a bracket 12.

In the roof 11 having a double air film structure, a wire 13 is attached to each bracket 12 and each wire 13
Is connected to a lifting jig 14 on the center of the double air film structure roof 11, and the lifting jig 14 is connected to the crane 1
5 can be lifted.

The installation and removal work of the double air film structure roof 11 is frequently performed not only at the start and end of the construction but also at the time of carrying in building equipment and materials during the construction.

[0012]

However, in the nuclear power plant construction method shown in FIG. 11, the curing dome 6 is opened and the reactor is housed by the tower crane 7 installed outside the steel frame 4. Since a pressure vessel or the like is carried into the vessel 4, a large crane is required for operating the curing dome 6, which increases the weight of the roof steel frame and increases the cost.

In addition, the work for installing and removing the large crane is required, which increases the cost. On the other hand, FIG.
In the temporary structure shown in FIG. 2, the crane 1
5, a large crane is required for mounting and removing the double air film structure roof 11, thereby increasing costs.

At the time of opening the ceiling, the double air film structure roof 11 is lifted by the crane 15, so that it is difficult to work in a strong wind. Since the double air film structure roof 11 is lifted and hung by the crane 15, there is a problem in the safety at the time of opening and closing.

Further, in the above-mentioned conventional structure,
Since the roof member that covers the ceiling of the large space for storing the reactor containment vessel and the roof member that covers the ceiling of the attached space are provided, there is a risk that the roof member may become heavy.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a building with a curing roof capable of reducing the weight of a roof steel frame and opening and closing without being affected by the weather. To provide.
