Conventionally, this type of construction method is known as Japanese Patent Publication No. 17869/1983. In other words, the base frame is vertically extended onto the exterior wall covered with dry-type exterior wall material and extends to the draining edge of the prefabricated wall, and the liner material is fixed to the foundation horizontally either directly or via an attached foundation. The starting material was fixed to this liner material, the first stage of new exterior wall material was installed, and the exterior wall was repaired by successively roofing.

In the construction method described above, the substratum is not fixed to the foundation, so it lacks stability, and there is a large difference between the dimensions of the starting material protruding outward from the foundation and the dimensions of the substratum protruding from the existing exterior wall. ,
There were disadvantages such as making it difficult to construct and spoiling the aesthetic appearance. Furthermore, since the liner material is directly exposed to the outside air, and moreover to the wind and rain, there is a drawback that the liner material and the starter material corrode. In addition, when installing new exterior wall materials horizontally or vertically, the surface of the base, the so-called existing wall, is often very uneven, and the height of the rim for the new wall base from the surface of the existing wall is The wall fell apart, and the new exterior wall material installed there became unstable, resulting in a lack of waterproofing at the joints, and the overall appearance of the wall was damaged.

Hereinafter, one embodiment of the exterior wall repair method according to the present invention will be described with reference to the drawings. FIGS. 1a and 1b are perspective views showing an example of the repair method according to the present invention,
Fig. a is a perspective view showing horizontal installation, and Fig. b is a perspective view showing vertical installation. Fig. 2 is an explanatory diagram showing the foundation part when new external wall material is installed horizontally using the repair method according to the present invention. is the frame of a prefabricated wall, for example, a stud; 2 is a prefabricated mortar wall structure (hereinafter simply referred to as a wall); 3 is a foundation; 4 is a foundation; 5 is a foundation drain; 6 is a height difference absorber; 7 is a vertical rim; 8 is the starter, 9 is the new outer wall,
10 is a new exterior wall material, and 11 is a nail. To explain further, the wall 2 has, for example, wood slate on the outer surface of the frame 1.
It consists of a mortar wall structure constructed in the following order: waterproof sheet, lath sheet, and mortar wall material. In addition, the foundation drainer 5 has a nail 11 parallel to the lower edge of the wall 2.
It is fixed to the base 4 through the opening, which mainly mounts the starter 8 , guides the vertical rim 7, and opens between the lower end surfaces of the vertical rim 7 arranged corresponding to the frame 1. The area is somewhat occluded. As a specific example, the base drainer 5 is a long body consisting of a vertical mounting part 5a, a horizontal or inclined drainer part 5b, and a vertical cover part 5c, as shown in FIGS. 3a to 3e. It consists of a plate (Al, Cu, Fe). The height difference absorbing material 6 (hereinafter simply referred to as absorbing material) mainly absorbs the height difference on the surface of the wall 2, and positions the surface of the vertical rim 7 on which the new external wall material 10 is attached on almost the same plane. The surface of the new outer wall 9 is made almost flush, and the wall 2 and the vertical rim 7 are blocked so that they do not come into direct contact with each other to prevent the vertical rim 7 from coming into contact with the wall 2 due to condensation or the like.
This prevents corrosion. Specific examples include synthetic resin foams, inorganic foams, such as soft polyurethane foams with cushioning properties,
polyethylene foam, polystyrene foam,
It is a felt-like material with a thickness of 1 to 10 mm made of one or more of phenol foam, KG sheet (trade name), and glass mat. Of course, the absorbent material 6 is fixed to the wall 2 or the vertical rim 7 with adhesive, adhesive tape, staples, pins, or the like. The shape thereof is, for example, as shown in FIGS. 4a to 4e. That is, figures a and b show absorbent material in the form of a belt, figure c shows a wide absorbent material, figure d shows an absorbent material in short pieces, and figure e shows an absorbent material 6 coated integrally with an impermeable sheet, such as a soft resin film or a polyethylene film. It is an equal absorbent material. In addition,
Figure b shows an absorbent material with adhesive tape 6a attached to both sides. Of course, although not shown, it is also possible to apply only the adhesive to one side of the absorbent material 6. Further, the vertical rim 7 is for fixing the new exterior wall material 10 that forms the new exterior wall 9 , and is perpendicular to the position corresponding to the frame 1 of the wall 2 and up to an appropriate height from the lower end of the wall 2. It is fixed to the frame 1 via nails 11 at appropriate intervals. That is, the lower end surface 7a of the vertical rim 7 is in contact with the draining portion of the base drainer 5, or is fixed to the frame 1 via the nails 11 with a certain gap. In addition, when the absorbent material 6 is attached integrally with the vertical furring 7, it is formed as shown in FIGS. 5a to 5d. That is, figure a shows the case where an absorbent material 6 with the same length and width as the vertical furring 7 is fixed to the vertical furring 7, figure b shows the case where a wide absorbent material 6 is fixed, and figure c shows the case where the absorbent material 6 with the same length and width as the vertical furring 7 is fixed. Figure d shows the case where the absorbent material 6 is fixed at a pitch P for each nail 11 driving position. The starter 8 described above is fixed to the lower end of the vertical rim 7 to lock the new exterior wall material 10, and its shape ranges from a long body with a cross section as shown in FIGS. 6a to 6f. Figures a to c are hanging type, and d to f are drop-in type new exterior wall materials 10.
This starter 8 is suitable for installing. That is, as shown in FIGS. 6a to 6f, a thin metal plate is formed into a substantially U-shape to form a nail driving part 8a, a bottom part 8b,
An engaging portion 8c having a U-shaped cross section is provided. In addition, the new exterior wall material 10 that covers the new exterior wall 9 is the seventh
It is an elongated body having a cross section as shown in Figures a to l, and its connection structure is either a hook type or a drop type. 12 is a new exterior wall material 1 with a waterproof sheet
0 and the vertical furring 7 as necessary. An example of the waterproof sheet 12 is asphalt felt, terfelt, etc., which mainly functions as a waterproof material.

Next, an embodiment of the exterior wall repair method according to the present invention will be described in detail. Now, in the ready-made wall structure as shown in FIG. 1a, first, the foundation drainer 5 is fixed horizontally to the lower end of the wall 2 with nails 11 as shown in FIG. Next, a vertical rim 7 as shown in FIG. The position is fixed as appropriate. Thereafter, the starter 8 is fixed to the vertical flange 7, the first stage new exterior wall material 10 is engaged, and the upper end is fixed with nails 11. Therefore, in order to form the new exterior wall 9 , the process of attaching the new exterior wall material 10 on the lower tier to the new exterior wall material 10 on the upper tier can be repeated, for example, until the eaves can be successively roofed. Of course, well-known accessories will be fixed to the eaves.

As described above, according to the exterior wall repair method according to the present invention, there is no need to dismantle the existing exterior wall, so the number of construction steps can be omitted, and the construction period can be significantly shortened. It has features that do not cause any problems. In addition, because the absorbent material is interposed between the wall and the rim, even if the wall surface is uneven, the height from the wall of the rim, which is the base to which the new exterior wall material is installed, is located on almost the same plane. It has the characteristics of being a new exterior wall with a stable base and beautiful appearance. Further, when an outer wall is formed using the outer wall repair method according to the present invention, it has a double wall structure with an existing wall, and has the characteristic of becoming a wall structure that is rich in heat insulation, soundproofing, and fireproofing properties.
