DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for repairing a building outer wall whose outer wall is formed of an ALC plate.

[0002]

2. Description of the Related Art ALC plates (cellular concrete or lightweight cellular concrete) are lightweight and excellent in heat insulation, sound insulation and fire resistance performance. Is what it is.

Many of these properties largely depend on the porous nature of the ALC plate, but also have the disadvantage of high water absorption. For this reason, when it is used for an outer wall or a roof, it is necessary to perform a sufficient waterproof treatment on the surface. Painting is effective for waterproofing,
Since the building surface is repeatedly dried and wet over many years, as the age of the building increases, the surface deteriorates and the adhesion of the paint decreases.
For this reason, when painting the deteriorated ALC outer wall, there arises a problem that a pretreatment operation such as scraping off the surface at the time of painting is required.

[0004] If the outer wall of the ALC deteriorates, a method of replacing it with a new outer wall is conceivable, but this method is not always advantageous in terms of waste material treatment or construction cost.

[0005] In order to solve the above problems, a construction method has been developed in which an exterior material is attached to the surface of an existing outer wall, the characteristics of the ALC plate are left, and the building surface is beautifully repaired.

As an example of the prior art, Japanese Patent Application Laid-Open No. 2-101
251 and Japanese Unexamined Patent Publication No. 4-38363.

[0007] The former of the prior art, as shown in FIG.
The metal fitting 4 for attaching the exterior material to be attached to the outside of the outer wall C is fixed to the building frame (H-shaped steel) 1, but not all the metal fittings are fixed to the frame 1 and a part of the metal fitting 8 is fixed to the anchor 9.
Is fixed to the ALC plate. However, even if the anchor is driven into the ALC plate whose surface has deteriorated, there remains a problem that the anchor strength for supporting the exterior material against wind pressure or the like cannot be sufficiently obtained.

On the other hand, in the latter case of the prior art, as shown in FIG. 6 , a metal member 6 for mounting a panel provided on the outer wall of a building is fixed to the ALC plate 1 by the fixing member 2. Therefore, there is a problem that the exterior material mounting strength is not sufficient.

[0009]

SUMMARY OF THE INVENTION The present invention does not damage the ALC plate by directly fixing the support for attaching the exterior material to the outside of the ALC outer wall to the building frame without applying a load to the ALC plate. The purpose of the present invention is to provide a refurbishment device which can be fixed securely .

[0010]

Means for Solving the Problems A solution is to insert a support bracket through a core-piercing hole penetrating the outer wall of the ALC and fix the support bracket to a building frame. A fixing device for fixing an outer member to a vertical trunk edge or a horizontal trunk edge fixed to the outside of an ALC outer wall, wherein a support bracket 10 is formed by an outer member and an inner member, and both are formed in a longitudinal direction. It is characterized by being telescopic and adjustable in overall length.

The support fitting 10 of the representative embodiment is a cylindrical body having a bottom having both an outer member and an inner member, a female screw provided on an inner peripheral surface of the outer member, and a male screw provided on an outer peripheral surface of the inner member. Are provided, and they are screwed to each other so that they can expand and contract in the length direction.
There is a feature.

In the renovation work, the support fitting 10 is inserted through the coring hole 40 formed in the ALC outer wall 3 and fixed to the building frame 1 of the building. The support member 10 adjusts the length by relatively moving the outer member 11 and the inner member 12 . Next , the vertical body edge 20 is fixed to the support fitting 10, and the horizontal body edge 30 is fixed to the vertical body edge 20. The exterior material 50 covering the surface of the building is fixed to the horizontal trunk 30. Since the entire length of the support bracket 10 can be adjusted,
The thickness of the ALC outer wall and the frame outside the ALC outer wall
It can also respond to differences in distance to the waistline .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a state in which a vertical body edge and a horizontal body edge for attaching an exterior material are provided outside an ALC outer wall, FIG. 2 shows a vertical section of FIG. 1, and FIG. FIG. 4 shows a typical embodiment of the support fitting.

In these figures, reference numeral 1 denotes a frame of a building, which is formed of H-shaped steel, and forms an outer wall by connecting an angle type mounting bracket 2 and a reinforcing bar 4 provided at a joint portion of the ALC outer wall 3. ing. In FIG. 2, the right side of the ALC outer wall 3 is the inside of the building. Reference numeral 10 denotes a support fitting which is fixed to the skeleton 1. An outer member 11 and an inner member 12 are provided.
The two members are connected so as to be able to expand and contract in the axial direction.

[0015] A typical embodiment of the support fitting is the outer member 11.
The inner member 12 and the inner member 12 are both cylindrical bodies having a bottom, and both are screwed to each other with the fixing bottom part outside. That is, a female screw 13 is provided on the inner peripheral surface on the opening side of the outer member 11, and a male screw 14 is provided on the outer peripheral surface of the inner member 12. 1
