DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building and a building
The present invention relates to a structure for repairing an existing outer wall made of C member (lightweight cellular concrete) with a new outer wall. More specifically, the connection base material for attaching a new drywall material is an export beam structure that is directly fixed to the building frame (base material) without applying a load (load) to the ALC outer wall, The present invention relates to a repair structure of an ALC outer wall which does not damage an outer wall and has a sufficient installation strength of a new dry wall material.

[0002]

2. Description of the Related Art Conventionally, the renovation of an outer wall using an ALC member has been carried out by removing all the old ALC outer walls and forming a new outer wall 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 wall itself as a wall base material is generally known.

[0003]

However, as described above, all of the old ALC outer walls that have become old have been removed,
In the structure where the new outer wall is formed on the existing base material such as the frame and the rim, there is a problem in increasing the cost for removal and disposal of the removed waste material, and there is no outer wall during construction,
During the construction period, there was a problem that it became impossible to live or work in the building or use the inside of the building.

Further, in a structure in which an ALC outer wall is used as a wall base material as it is 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. The use of this as a wall base has a problem with the strength of the new wall material that has been installed, and has the risk of falling off or peeling off due to external impacts such as typhoons and earthquakes. . 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,
Irregularities also occurred on the new wall surface that had risen, and the appearance was inferior.

[0005]

According to the present invention, in order to eliminate such a drawback, a through hole is formed at a position where a base material of the existing ALC outer wall is provided, and a connecting base material is formed in the through hole. It was inserted and fixed to the base material with a rivet gun, and the other end was fixed to the rim arranged on the surface of the ALC outer wall, and a new dry wall material was fixed to this rim. The construction is easy and the mounting strength is secure without compromising the living environment.
C It is possible to cope with the difference in the thickness of the outer wall and to adjust unevenness, improve the aesthetics of the rise of the new dry wall material, and use stud welding to fix the base material and the connecting base material. The ALC can be easily fixed and can be completed in a short time, greatly improving the workability, and the ALC that can be repaired without using any load (load) on the existing ALC outer wall as a connecting base material as an export beam structure It proposes a renovation structure for the outer wall.

Using a device such as a shotgun for shooting, and instantly,
Securely attach and attach. At this time, care should be taken that the outer periphery of the bolt D3 does not touch the through hole C so as not to apply a load to the ALC outer wall B.

Then, as shown in FIG. 14, the nut D2 is screw-connected to the bolt D3 with the screw while rotating the nut D2. Further, as shown in FIG. 15, the nut 2 is screwed and attached to the nut D2 while rotating the bolt 2 of the metal fitting D1 with the bottom. At this time, if a tool such as a screwdriver is inserted into the tool locking hole 4 of the metal fitting D1 with the bottom and rotated, the work becomes easier. It should be noted that, depending on the degree of rotation of the bottomed bracket D1 and the bolt D2, the entire length of the connecting bracket D is expanded and contracted, and the unevenness is adjusted so that the bottom piece 1 is at the same height as the surface of the ALC outer wall B. Things.

Next, as shown in FIG. 16, the groove 12 of the elongated lateral body edge E1 is fixed to the bottom piece 1 exposed from the through hole C via the fixing tool β. Then, as shown in FIG. 17, the vertical body edge E2 is fixed to the horizontal body edge E1 at intervals of the pitch P1 using the connection fittings G1 and G2. The pitch P1 at this time is determined by a required waistline pitch of the dry wall material F to be attached, wind resistance against ground height, and the like, and is, for example, 600, 900, 1200, or 150.
0, 2000 mm or the like.

Finally, as shown in FIG. 1, the horizontal wall type dry wall material F is attached to the lip portion 13 of the vertical waist edge E2 by using a fixing tool β to complete the repair. Of course, although not shown, draining material, starter material, rim material, outgoing and entering corner materials,
Various external materials such as an opening member and a sealing material are constructed as needed to form a new outer wall surface.

In the structure shown in FIG. 28, the gap between the through hole C and the connecting base material D is filled with the filler H to reinforce the heat insulation and the wall strength lost by the formation of the through hole C. The structure has improved waterproofness and airtightness. In addition,
Examples of the filler H include a mortar, rock wool, a heat insulating mat such as a glass fiber mat, and an irregular sealing material.

FIG. 29 shows an example of the mounting arrangement of the rim E when the dry type wall material F is of a vertical type. In this case, the intermediate portion is provided between the vertical rim E2 at a required arbitrary pitch. By attaching and arranging the horizontal torso edge E3, the horizontal torso edge E1 and the intermediate horizontal torso edge E3 function as a foundation for the dry wall material G. In this case, an L-shaped angle member, a hollow square pipe, or the like can be used for the intermediate horizontal trunk edge E3.

As described above, according to the ALC according to the present invention,
According to the renovation structure of the outer wall, it is not necessary to dismantle the existing ALC outer wall, so that the number of construction steps can be reduced, the construction period can be significantly reduced, and there is no hindrance to living and use during construction. Absent. Since the new outer wall is formed on the existing ALC outer wall, the construction is easy and the cost can be saved. It has a double wall structure of the existing ALC outer wall and a new dry wall material, and has a structure with excellent heat insulation, soundproofing, and fireproofing properties.
By forming through-holes in the ALC outer wall, the installer can directly check the underlaying material directly from the surface side of the ALC outer wall, and the attachment of the connecting underlaying material to the underlaying material is ensured. The mounting strength does not deteriorate. By providing the connecting base material with the expansion and contraction function, unevenness of the base material can be easily adjusted, construction is facilitated, and the aesthetic appearance of the dry wall material is improved. Since the connecting base material is a take-out beam structure, it does not touch the through-holes or the existing ALC outer wall at all, so no load (load) is applied to the existing ALC outer wall.
The ALC exterior wall can be repaired without the need for installation, and the strength of the new drywall material is sufficient and the ALC outer wall is not damaged. Fixing the connection base material to the base material is done using a shotgun,
Compared to using a fixture or the like, it can be firmly fixed instantaneously, greatly improving workability. There are effects and features such as.
