2. Description of the Related Art Conventionally, buildings made of reinforced concrete are
When building by casting concrete in a formwork, the following construction method was used.

That is, as shown in FIG. 10, a formwork is formed on a floor 81 to form all the walls 83 provided on the floor and a floor 85 on the upper floor, and concrete is poured into the formwork. And then harden, then remove the formwork to build all the walls 83 of this floor and the floor 85 of the upper floor, and perform this work sequentially from the lower floor to the upper floor Was building a building. In the room 80 from which the formwork has been removed, the water surrounding equipment 87 is installed, or work such as partitioning each room is performed.

However, such a conventional construction method has the following problems. Since a formwork for building all the walls 83 and the like on the floor at one time is assembled, a large amount of formwork members such as plate materials necessary for the formwork are required, and the cost of building materials cannot be reduced.

When the formwork for forming the wall 83 and the floor 85 of the upper floor is assembled, the floor 85 is weighted by the weight of the concrete poured.
The conventional floor 8
Although it was necessary to install a formwork support for supporting the formwork No. 5 from below, the work was also complicated from this point, and the cost of building materials could not be reduced.

[0006] In the case of installing the water surrounding equipment 87 or partitioning the room, these equipments are too large as finished products and cannot be carried in from the entrance or exit of the room 80 or the window. In the room 80, and must be assembled and installed in the room 80. Therefore, the work has been complicated.

It was configured to build the whole building. The present invention also provides
In the construction method of a building in which a plurality of rooms on the same floor are constructed by placing concrete in a formwork, a wall of one room is built, and then a wall of the one room is built. The wall of each room was constructed sequentially by repeating the process of building the wall of the next room using the formwork used to build the room.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 9 are diagrams showing a construction process of a building constructed using the present invention, wherein FIG. 1 (a) is a schematic plan view and FIG. 1 (b) is a schematic side sectional view. Note that a veranda, stairs, and the like are actually installed in this building, and a reinforcing bar is built in the formwork, but these are omitted for the sake of simplicity.

In order to construct this building, as shown in FIG. 1, first, a formwork A serving as an outer wall of the first room on the first floor is assembled, and concrete is poured into the formwork A. Note that before actually assembling the formwork, a reinforcing bar is actually set in that part, but the description of the reinforcing bar set will be omitted below. The floor of the first floor, which is the foundation of the building, is not shown, but is formed by casting concrete in advance.

Next, in FIG. 2, after removing the form A, a form B serving as a wall for partitioning a room is assembled.
Concrete is poured into it as shown in FIG. Thus, the wall of the first room 101 on the first floor is completed. At this time, the ceiling of the first room 101 is not open and is open. Then, the mold B is removed after the concrete reaches a predetermined hardness.

Next, referring to FIG. 4, the completed room 1
From the open upper part of the wall of No. 01 (the part to be the ceiling), the water surrounding equipment 10 previously integrated with a bathtub and a toilet in a factory is lifted by a crane and inserted and mounted therein. At the same time, the interior walls 11 and the like separating the rooms in the first room 101 are inserted from the upper part opened by a crane or the like and assembled.

As described above, according to the present invention, a ceiling portion is not formed when a wall is constructed, and various indoor facilities such as a water plumbing facility 10 are inserted from above the wall into a room covered with the wall. Since there is no need to carry various indoor equipment through doorways or windows as in the conventional construction method that creates a ceiling along with walls, it can be easily carried in by a crane, and its manufacture becomes easy. In particular, conventionally, even a unit bus or the like is transported as a component into a room and assembled in the room, but according to the present invention, the completed unit bus itself can be easily transported into the room. In particular, in the case of this embodiment, instead of the unit bath alone, the water surrounding equipment 10 integrating the bath and toilet etc. was assembled at the factory into a unit, and this was inserted into the room with a crane as it was, and set. Workability can be significantly improved.

Next, referring to FIG. 5, the form B removed to form the wall of the first room 101 is removed from the second room 102.
Is reassembled as a formwork B for making a wall, and concrete is poured into it. At the same time, Room 1 101
A formwork C to be the floor of the first room 201 on the second floor is assembled on the wall, and concrete is poured into the formwork C. At this time, since the formwork C is supported by the water surrounding equipment 10 and the indoor wall 11 housed in the first room 101 on the first floor, the formwork C does not bend due to the weight of the concrete to be cast, and is therefore conventionally required. The former formwork support was no longer necessary (or improved with only a few). Then, when the concrete reaches a predetermined hardness, the molds B and C are removed.

Then, as shown in FIG. 6, after inserting and installing various indoor facilities such as the water surrounding facility 10 in the second room 102, the mold B and C are used to remove the wall for the third room 103 using the removed formwork B and C. A floor form for the second room 202 on the second floor is assembled, and concrete is cast in the same manner as above to remove the forms B and C.

After the walls of the fourth room 104 are constructed in the same manner, a formwork A to be a wall for the outer wall of the first room 201 on the second floor is assembled as shown in FIG. Set up. This form A is the first room 10 on the first floor in FIG.
It has been removed to make the wall for the outer wall of No. 1. At the same time, a formwork C to be the floor of the fourth room 204 on the second floor is assembled also on the wall of the fourth room 104 on the first floor, and concrete is poured into the inside.

A second floor is constructed as shown in FIG. 8 and a third floor is further constructed as shown in FIG. 9 by using the same construction method. Things are completed.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical idea described in the claims. . For example, the building to be built may be one or two stories or four or more stories. Further, in the above embodiment, the water surrounding equipment 10 is shown as one in which a bath and a toilet are integrated, but it is needless to say that these may be separately installed.

[0020]

As described in detail above, the present invention has the following excellent effects. Since various indoor facilities such as water surroundings are inserted and installed from the upper side of the wall inside the room surrounded by the wall, it is easy to install various heavy indoor facilities by using a crane and disassemble various indoor facilities It can be inserted into the room without the need, significantly improving workability and shortening the period of interior interior work. In addition, since the installed various indoor facilities themselves replace the formwork support that supports the formwork for making the floor of the upper floor, the formwork support that was required conventionally becomes unnecessary or requires only a small number, and building materials Cost can be reduced.

After building the wall of one room,
To repeatedly build the walls of the next room using the formwork used to build the walls of one room, the walls of each room can be built sequentially, so to build walls etc. And the cost of building materials can be reduced.
