DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building in which an old outer wall of an existing building has been renovated by a new outer wall, and a method of renovating the same.

[0002]

2. Description of the Related Art It is known to renovate an existing building by repairing an outer wall or using another outer wall material. In such a case, there is a method in which the old outer wall used as the conventional outer wall is removed, peeled off, or scraped off from the building frame, and then the new outer wall is displayed. In this method, it takes a long time to remove the old outer wall, and dust and the like may be scattered in the vicinity, which is a problematic construction method.

In response to this problem, there is known a construction method in which a new outer wall is mounted on an old outer wall without removing the old outer wall. In this method, a support material is fixed from above the old outer wall, and the new outer wall is attached thereto. According to this method, apparently the outer wall is thicker,
In windows and the like, there is a problem that the new outer wall travels considerably, and it is desired that the distance between the old outer wall and the new outer wall be reduced as much as possible by devising a supporting material. A new window is set up on the new outer wall to take the shape of a bay window,
Japanese Patent Publication No. 4-42513 discloses that the indoor use space is to be substantially expanded.
The use space is expected to be used for placing flower pots and small ornaments, and for use as a space for attaching a curtain rail, and it is assumed that the space between the old outer wall and the new outer wall is to be made as small as possible.

[0004] Even if the exterior wall is renovated at high cost by the above-mentioned construction method, there is no particular contribution to the function of the building itself, and the heat insulation effect of the exterior wall is slightly improved,
A bay window was formed.

[0005] In addition, names such as intelligent buildings have come to be used, and in recent buildings, various equipment such as electric facilities, plumbing sanitation facilities, communication facilities, and gas facilities have been used in various ways. I have. In an old building, when installing or expanding these equipment, space for installing the equipment,
In some buildings, there is no space to secure such piping and ducts for wiring, and it is not possible to cope with the intelligent system.

[0006] In an old building that has been constructed before, a small amount of power receiving equipment is usually installed because there are few power devices. In addition, the wiring inside the building is thin, and the current capacity is small. In such a building, the power supplied to each room cannot be increased to the required amount even if the power receiving equipment alone is enlarged. When renovating a building, it is necessary to increase the power consumption. However, as described above, there is also a problem that it is impossible to increase the supply power capacity in the facilities in the old building.

[0007]
