Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a construction method for repairing an exterior wall of an architecture or structure, particularly an existing wall constructed by a dry construction method.

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

(Problems to be Solved by the Invention) In the construction method described above, the substratum is not fixed to the foundation, so it lacks stability and there is a large gap between the protrusion dimension of the starting material from the foundation and the protrusion dimension of the substratum. Differences may occur, making construction difficult, and there are disadvantages such as spoiling the aesthetic appearance. moreover,
Since the liner material is exposed to the outside air and is exposed to wind and rain, there is a drawback that the liner material and starter material corrode.

(Means for Solving the Problems) In order to solve these drawbacks, the present invention extends the vertical rim, which has the same function as the base bone, from the position of the base to the required height, and furthermore, extends the vertical rim, which has the same function as the base bone, to the required height, and also extends the vertical rim, which has the same function as the base bone, to the required height. While fixing the lower end of the vertical rim to the batten with a batten interposed,
The gap at the lower end between the vertical rims is covered with a covering material, and a starter for installing the first stage of new exterior wall material is fixed to the lower end of the vertical rim, and a new exterior wall is roofed.

(Function) The above-mentioned batten prevents the lower end of the vertical hemline from being exposed to the outside air, securely attaches the covering material that closes the space between the vertical hemlines, and keeps the lower end of the vertical hemline in a stable state. Since the starter is fixed to the lower end of the vertical rim as described above, it has a robust structure, and the lower end of the new wall is directly exposed to wind and rain due to the starter, sheathing material, and the back of the new exterior material. Covered to prevent exposure.

(Example) Hereinafter, an example of the outer wall repair method according to the present invention will be described using the drawings. Fig. 1 is a perspective view showing an example of the repair method according to the present invention, and Fig. 2 is an explanatory diagram showing the foundation part of the repair method according to the present invention.
is a stud, 2 is a prefabricated wall (hereinafter simply referred to as a wall),
It is a ready-made wall structure. To explain further, the existing wall structure has slate plates, metal, etc. on the outer surface of stud 1.
The structure is made of wall materials such as ceramic siding boards. 3 is a foundation, 4 is a base, and 5 is a batten, which is the same as the thickness T of wall 2 or somewhat smaller, and is fixed to the lower part of foundation 4 parallel to foundation 4, and covering material 6 is shown below. This is to securely fix the vertical furrow 9 in a stable state. In addition, the covering material 6 is formed of an L-shaped cover part 7 and a draining part 8, as shown in FIGS. The opening surface between the longitudinal edges 9 is covered, and the drain section 8 drains the lower end of the new outer wall, and the function of closing the opening surface is reinforced. Further, the material of the covering material 6 is one of metal plates (Fe, Al, Cu, aluminum, zinc alloy plated steel plates, stainless steel), plastic plates, and the like. In addition, figure b shows a covering material integrally formed with a starter, which will be described later, and figure c shows a modified version of the draining part 8. The size is larger by that amount. The vertical rim 9 is for fixing the dry exterior wall material 15 forming the new exterior wall 14 , and is fixed vertically via nails 17 at a position corresponding to the frame of the wall 2. That is, the lower end of the vertical trunk rim 9 is attached to the outer surface of the batten 5 with a nail 1.
7, and the other parts are fixed to the studs 1 at appropriate intervals. Reference numeral 10 denotes a starter which is fixed to the lower end of the vertical flange 9 and locks the outer wall material 15, and its shape is a long body with a cross section as shown in FIGS. 4a to 4f. , a~
Fig. c shows a hook type material, and d to f show a drop-in type material suitable for attaching the exterior wall material 15. That is, as shown in FIGS. 4a to 4f, a thin metal plate is formed into a substantially U-shape to form a nail driving part 11 and a bottom part 1.
2. An engaging portion 13 having a U-shaped cross section is provided. Further, the dry exterior wall material 15 is a long body having a cross section as shown in FIGS. 5a to 5k, and its connecting portion structure is either a hook type or a drop type. 1
A waterproof sheet 6 is provided between the wall 2 and the vertical rim 9 as necessary. An example of the waterproof sheet 16 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 a ready-made wall structure as shown in FIG. 1, the battens 5 are first fixed to the base 4 via nails 17 as shown in FIG.
Next, the lower end of the vertical rim 9 is brought into contact with the outer surface of the batten 5 as shown in FIG. 2, and that portion is fixed with nails 17. In addition, the other part of the vertical rim 9 is connected with nails 17,
Fix it to stud 1 at appropriate intervals. Next, starter 1
0 is fixed to the lower end of the vertical furring 9, the first stage outer wall material 15 is engaged, and the upper end is fixed with nails 17. Therefore, in order to form a new outer wall 14 , the above steps are repeated until the eaves are successively roofed.

What has been described above is only one embodiment of the exterior wall repair method according to the present invention, and the batten 5 and starter 10 may not have a through structure but may be short members. Furthermore, a waterproof sheet may be interposed at the position indicated by the two-dot chain line in FIG.

(Effects of the Invention) As described above, according to the exterior wall repair method according to the present invention, there is no need to dismantle the existing wall, so the number of construction steps can be omitted, and the construction period can be significantly shortened. It has the characteristic that it does not cause any hindrance to living inside. Furthermore, during construction, the batten was fixed to the foundation, and the lower end of the vertical rim was fixed to the batten, making it possible to securely secure the vertical rim in a stable state. In addition, by fixing the vertical rims to battens and covering the space between the vertical rims and the lower end surface of the vertical rims with a covering material on the outside surface of the lower end to protect the lower ends of the vertical rims from wind and rain, It has the characteristic of blocking air from inside and outside by cooperating with the exterior wall material. There is no need to fix the liner material as in the past, and construction is easy.
Moreover, it has the characteristic of being highly efficient. 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 with excellent heat insulation, soundproofing, and fireproofing properties.
