Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a basement, and more particularly to a technique for significantly improving the workability in constructing a basement.

[0002]

2. Description of the Related Art Conventionally, to construct a basement, a hole is dug at a construction site by excavation, a concrete formwork is assembled at such a construction site, and reinforcement is carried out.
After pouring concrete and curing and drying the concrete, the concrete formwork is removed to construct a basement.

[0003]

However, in such a construction method, a concrete form is assembled,
Since the concrete formwork is removed after the curing and drying of the concrete by arranging the concrete, the work is troublesome and the interior is done after the curing and drying. However, there is a problem in that it is not possible to obtain a highly accurate finish, the workability is low, the construction period is long, and it is difficult to improve the finish accuracy. In order to solve such a problem, a construction method of forming a basement unit in a factory, transporting it to the site, and placing concrete in the basement unit is also considered, and the present inventors propose as Japanese Patent Application No. Hei 3-152772. ing. However, when constructing the whole basement unit in a factory like this, the form of the basement unit is determined, the degree of freedom of the basement configuration is suppressed, and it is integrated to handle a large basement unit.
It required a large crane and left problems in terms of transportation and handling.

The present invention has been made in view of the above problems, and an object of the present invention is to improve the workability significantly and to provide a basement which has sufficient strength and is advantageous in terms of transportation and handling. There is to try to provide a build method.

According to the present invention, at least an end where a wall portion 2 on one side is opened by forming a cavity 4 for pouring concrete in which a reinforcing bar 3 is arranged in at least a floor portion 1 and a wall portion 2. Part unit 5 and an intermediate unit 6 in which the facing wall surface part 2 is open, and the reinforcing bars 3 of each unit 5, 6 are formed.
To the opening side, and a hook 12 is formed at the projecting end, and the reinforcing bars 3 are connected to each other via the hooks 12 of the reinforcing bars 3 of the units 5 and 6 so that the units 5 and 6 contact the opening side. Then, the basement unit 7 is assembled, and each void 4
It is characterized by constructing a basement by pouring concrete into it.

[0006]

As described above, the end unit 5 in which at least the floor portion 1 and the wall surface portion 2 are formed with the voids 4 for pouring concrete in which the reinforcing bars 3 are arranged and the wall portion 2 on one side is opened
And an intermediate unit 6 in which the facing wall surface portion 2 is opened, the reinforcing bar 3 of each unit 5, 6 is projected toward the opening side, and a hook 12 is formed at the projecting end portion.
The reinforcing bars 3 are connected to each other via the hooks 12 of the reinforcing bars 3 of 6, and the units 5 and 6 are brought into contact with their opening sides to assemble the basement unit 7, and concrete is placed in each of the voids 4 to form the basement. By arranging the end units 5 on both sides, arranging the intermediate unit 6 in the middle, and connecting and connecting the hooks 12 at the protruding ends of the reinforcing bars 3, the basement unit 7 is assembled, By pouring concrete into the voids 4 of the units 5 and 6, the basement can be constructed, the workability is greatly improved, and the construction period is short, and in particular, the end unit 5 and the intermediate unit 6 are divided. By doing so, the transportation and handling can be performed easily, and the flexibility of the configuration of the basement is increased by increasing or decreasing the number of the intermediate units 6, and in particular, the reinforcing bars 3 are connected to each other via the hooks 12 at the projecting ends of the reinforcing bars 3. By connecting, when concrete is cast, in which so as to increase the strength of connection between the units 5,6.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings. Between the FRP or wooden outer casing 8 and the FRP or wooden inner casing 9, the floor portion 1 and the wall surface portion 2 form a void portion 4 for concrete pouring, and the void portion 4 is provided with a reinforcing bar 3. Has been done. A waterproof layer is formed on the inner surface of the outer casing 8. Reinforcing ribs 10 are attached to the inner surface of the inner casing 9 to increase the strength of the inner casing 9. An interior material 11 is applied over these reinforcing ribs 10, and a moisture-proof layer is formed on the outer surface of the interior material 11. Interior material 1
The gap between 1 and the inner casing 9 is filled with a heat insulating material, but this gap may be used for the wiring space, water supply, and gas piping space. And, as mentioned above, the floor part 1
And an end unit 5 in which a void 4 for pouring concrete in which the reinforcing bars 3 are arranged is formed in the wall surface portion 2 and the wall surface portion 2 on one side thereof is open, and an intermediate unit in which the opposing wall surface portion 2 is open And 6 are configured. Further, the reinforcing bars 3 of the units 5 and 6 are projected to the opening side. A hook 12 is formed on the protruding end portion.

The end unit 5 manufactured at the factory
And the intermediate unit 6 are transported to the site by truck,
As shown in FIG. 1A, the basement unit 7 is assembled by bringing the opening side into contact with each other. In such a case, FIG.
As shown in (b), the hook 12 of the reinforcing bar 3 receives the receiving bar 13
The reinforcing bars 3 are connected to each other to be meshed with each other. Any form may be used to connect the reinforcing bars 3 to each other via the hooks 12, and various design changes are possible.

In this manner, the floor unit 1 and the wall unit 2 are opposed to the end unit 5 in which the reinforcing member 3 is arranged in the space 4 for pouring concrete and the wall unit 2 on one side is opened. An intermediate unit 6 having a wall surface 2 opened is configured, and the reinforcing bars 3 of the units 5 and 6 are projected toward the opening side,
A hook 12 is formed at the projecting end, and the reinforcing bars 3 are connected to each other via the hooks 12 of the reinforcing bars 3 of the units 5 and 6, and the units 5 and 6 are brought into contact with their opening sides to assemble the basement unit 7. By placing concrete in each void 4 to construct a basement, the end units 5 are arranged on both sides, the intermediate unit 6 is arranged in the middle, and the hooks 12 at the protruding end of the reinforcing bar 3 are arranged. Assembling the basement unit 7 by connecting and connecting the reinforcing bars 3 to each other through each unit 5,
The basement is constructed by pouring concrete into the voids 4 of 6. By thus dividing the end unit 5 and the intermediate unit 6, the transportation and handling thereof can be easily performed, and the degree of freedom of the configuration of the basement is increased by increasing or decreasing the number of the intermediate units 6. .. Then, the reinforcing bars 3 are connected and connected to each other via the hooks 12 at the protruding ends of the reinforcing bars 3, thereby increasing the connection strength between the units 5 and 6.

The interior material 11 may be constructed in a factory, but may be constructed later. Further, although the ceiling part may be opened to the end unit 5 and the intermediate unit 6, a ceiling plate may be additionally provided.
