DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material for a reinforced concrete building for rebuilding a reinforced concrete building and a method for rebuilding a reinforced concrete building.

[0002]

2. Description of the Related Art Conventionally, when building a middle-rise or high-rise apartment house made of reinforced concrete such as an apartment or a corpus, a crane or the like is used to raise a building material such as a large panel structure that divides a living space, and raises a building material for each floor. It is being built sequentially upward.

[0003] When renovating a residential section of a reinforced concrete building such as a condominium or a corpus that has already been built due to changes in the family structure, living environment, or the number of years of residence, for example, a crane vehicle is used to pull up building materials and use a window or the like. Therefore, large-sized panel structures cannot be used because the building must be brought into the living section to be renovated through the building or the building materials must be brought in using the elevator. In addition, since a work space is required, all building materials cannot be carried in. Therefore, it is necessary to carry in building materials appropriately according to the progress of remodeling. If another resident is already occupying a multi-family house or the like, traffic restrictions may be imposed when carrying in the materials, or the crane vehicle may be damaged due to the relationship with trees or other existing buildings. It is difficult to carry out large-scale transportation using the.

[0004] From this, when renovating a living space of a reinforced concrete building such as an apartment or a corpus, conventionally, a square bar or a plate material is carried in, and the square bar or the plate material is appropriately processed and assembled in the living section to be remodeled, and the floor or the floor is assembled. Ceilings and walls are being constructed.

[0005]

However, the above-mentioned conventional construction method for processing and assembling a square material or a plate material involves a problem that the reconstruction work requiring technology for the reconstruction work is complicated, the reconstruction period is lengthened, and the reconstruction cost is increased. is there.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a building material for a reinforced concrete building and a method of rebuilding the reinforced concrete building which can be easily remodeled, shorten the remodeling period, and reduce the remodeling cost. And

[0007]

According to a first aspect of the present invention, there is provided a building material for a reinforced concrete building, in which a square member is formed in a frame shape, and the frame material is attached to at least one surface of the frame shape and is continuous from one side and partially continuous. A pair of panel structures provided with a plate member that opens and closes, and a closing plate that connects the panel structures attached to the frame members of these panel structures that are not closed by the plate members, respectively, by closing the openings. It is provided with.

[0008] A pair of panel structures having a plate member attached by opening a part facing one side on at least one surface of the frame member in which the square member is formed in a frame shape are connected to each opening of the frame member not closed by the plate member. The panel structure is connected by connecting the panel structure by closing and closing the obstruction plate, for example, it is possible to form the panel structure in advance to a size that can be carried into the elevator, and it is easy to carry in and work on site It is only necessary to connect the panel structures, and the construction is easy and the renovation period is shortened to improve the workability, and the panel structures of the same shape are connected and constructed, so the panel structure can be easily formed Thus, the cost is reduced.

According to a second aspect of the present invention, there is provided a building material for a reinforced concrete building according to the first aspect, wherein one of the panel structures is closed by a closing plate on one surface of the frame. And a base board that opens a ventilation opening in a part facing one side opposite to the side, and closes the ventilation opening to open a ventilation slit.

In one of the panel structures, a ventilation opening is formed in a part of one surface of the frame-shaped object facing one side opposite to the opening closed by the closing plate, and a ventilation slit is formed. Since the open baseboard is attached by closing the ventilation opening of the panel structure, moisture is hidden in the renovated living space and between the panel structure and the reinforced concrete building, causing mold generation and panel structure Prevents body decay and damage.

In this way, noise from the upper floor can be cut off and noise can be prevented from leaking to the lower floor,
The air layer of the sound insulating member 24 also provides a heat insulating effect, and can easily save energy.

Further, before the floor structure 5, ceiling structure 7 and wall structure 10 are formed, a heat insulating material 11 is applied in advance to provide a heat insulating layer 12, so that each floor structure 5, ceiling structure 7
It is not necessary to provide a heat insulating structure in each panel structure constituting the wall structure 10, and since the heat insulating material 11 such as urethane board which can be carried in by an elevator is used, heat insulating work can be easily performed, and energy saving can be easily achieved. I can do it.

Further, since all existing parts such as ceilings, walls, floors and the like are removed in the remodeling, a structure similar to a new building can be obtained.

Further, since a panel structure is provided to communicate from under the floor to the ceiling and the air is exhausted almost forcibly by the exhaust device 53 disposed at the ceiling and the back, moisture hidden inside can be removed, and damage to each member can be prevented. Can be prevented.

In the above embodiment, the remodeling of the reinforced concrete building 1 of the apartment house has been described. However, any one of the reinforced concrete buildings 1 that can obtain strength in a structure such as a detached house can be used. The same effect can be obtained.

Further, depending on the structure of the building to be renovated,
For example, the construction order may be set as appropriate, for example, after the partition structure is constructed first, the floor structure 5 and the ceiling structure 7 are constructed sequentially.

Further, the heat insulating material 11 may be applied only to, for example, only the wall facing the outside, and may be applied to the floor, ceiling, and the boundary wall with the groove as required.
