Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for repairing an existing outer wall composed of an ALC outer wall (lightweight cellular concrete) of a building or a building with a new outer wall.

[0002]

2. Description of the Related Art Conventionally, a renovation of an outer wall using an ALC outer wall has a structure in which all of the old ALC outer wall is removed and a new outer wall is formed on a wall base material such as an existing frame or a rim. A new dry wall material is directly in contact with the outer wall surface of the ALC, and the dry wall material is fixed to the ALC using a fixture such as a concrete anchor.
A structure modified by using the LC outer wall itself as a wall base material is generally known.

[0003]

However, in the structure in which all the old ALC outer walls as described above are removed and a new outer wall is formed on the existing base material such as a frame or a rim, the removal of the old ALC outer wall is required. The cost of the construction is enormous, and there is no outer wall during the construction, and during the construction period, it is impossible to live or work in the building or to use the inside of the building. In addition, in the structure where the ALC outer wall is used as it is as a wall base material and a new wall material is constructed, the old ALC outer wall is cracked, partially dropped, and deteriorated in strength due to frost damage and aging due to its properties. However, the use of this as a wall foundation has a problem in the mounting strength of the new wall material that has been mounted, and has a risk of falling off or peeling off due to an external impact such as a typhoon or an earthquake. Furthermore, the surface of the ALC outer wall has irregularities, and if the new outer wall is constructed as it is, it is difficult to adjust the unevenness due to the irregularities, and irregularities also occur on the raised new wall surface,
The appearance was also poor.

[0004]

According to the present invention, a through hole is formed in the existing ALC outer wall at a position where the base material is provided, and a base base material is formed in the through hole. Inserting the connecting base material formed of two members with the extended base material, fixing one end of the connecting base material to the existing base material, projecting the other end to the ALC outer wall surface, and disposing it on the ALC outer wall surface The newly constructed drywall material is fixed to the rim, so that you can continue living during construction,
The construction is easy and the mounting strength is secure. Moreover, since the connecting base material is formed by connecting two members, the length of the connecting base material itself can be adjusted to some extent, and even if the thickness of the existing ALC outer wall is different. It is possible to cope with the same connecting base material and it is easy to adjust the unevenness, so we propose a renovation structure of the ALC outer wall with improved appearance and workability of the rising of the new dry wall material. is there.
