Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a construction method for modifying the exterior walls of buildings and structures, particularly existing exterior walls constructed by dry construction methods.

(Prior Art) Japanese Patent Publication No. 58-17869 is known as this type of construction method. 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 existing wall, and the liner material is fixed horizontally to the foundation either directly or through the foundation. The starting 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. There were disadvantages such as differences occurring, making construction difficult, and spoiling the aesthetic appearance. Furthermore, 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 the starting 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. The lower end of the vertical rim is fixed to the batten using a batten, and the gap between the lower end of the rim and the vertical rim is covered with a cover material. The first stage Stark was fixed and a new exterior wall was roofed.

(Function) The above-mentioned batten is designed to prevent the lower end of the vertical ribs from being exposed to the outside air, and to securely attach the cover material that closes the space between the vertical ribs in cooperation with the starter. The lower end is fixed in a stable state, and since the starter is fixed to the lower end of the vertical rim as described above, it has a robust structure.
Furthermore, the lower end of the new wall will be covered with a starter and covering material to prevent direct exposure to wind and rain.

(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. ), it is a ready-made wall structure. To explain further, the existing wall structure is one in which the outer surface of the stud 1 is made of a wall material such as a slate board, a metal base, or a ceramic siding board. 3 is a foundation, 4 is a foundation, and 5 is a batten, which has a thickness that is the same as the thickness T of the wall 2 or is slightly smaller, and is fixed to the lower part of the foundation 4 parallel to the foundation 4, and a cover material 6
, to securely fix the vertical furrow 10 described below in a stable state. Further, as shown in FIG. 3, the cover material 6 has a vertical portion 7 fixed to the outer surface of the batten 5 with nails 11, and an L-shaped portion '
8 has a guide portion 9 for housing the lower end portion of the vertical furring 10.

Furthermore, when a new wall is formed, the cover material 6 is
It has the function of closing the gap formed between the holes and protecting the lower end surface of the vertical furrow 10 and the outer surface of the batten 5 from wind and rain. This material is a metal plate (Fe, A
J2, Cu aluminum, zinc alloy plated Ii1, stainless steel) plastic plates, etc.

The vertical rim 10 is a dry exterior wall material 17 forming a new exterior wall.
It is fixed vertically at a position corresponding to the frame of the wall 2. That is, the longitudinal rim 1
The lower end of the wall 2 is inserted into the guide portion 9 and fixed to the batten 5 via nails 11, and the other parts are fixed to the frame of the wall 2, for example, the studs 1, with nails 11 at appropriate positions. 12
is fixed to the lower end of the vertical rim 10 with a starter, and the outer wall material 17
The shape is shown in Figure 4(a).
~(It consists of a long body as shown in fl, and (a
Figure l~FC1 shows the hook type, (d1~([1 is the starter 1 suitable for attaching the drop-in type exterior wall material 17.
It is 2. That is, as shown in FIG. 4 Ta> to (f), a thin metal plate is formed into a substantially U-shape, and the nailing steps 13,
A bottom portion 14 and an engaging portion 15 having a U-shaped cross section are provided. The dry exterior wall material 17 is a long body having a cross section as shown in FIGS. 5(a) to 5(k), and its connection structure is either a hook type or a drop type. A waterproof sheet 18 is provided between the wall 2 and the vertical rim 10 as necessary. An example of the waterproof sheet 18 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 wood 5 is first fixed to the base 4 with nails 11 as shown in FIG. Next, the cover material 6 is fixed horizontally in parallel with the battens 5 via nails 11, and the cover material 6 is
The lower end of the vertical rim 10 is fitted into the guide portion 9 of the stud 1, and held vertically at a position corresponding to the stud 1, and fixed at appropriate locations via nails 11. In addition, in this case, 1 for vertical use! The lower end of the to is fixed to the base 4 via a cover material 6, a batten 5, and a nail 11. Next, the starter 12 is fixed to the lower end of the vertical furring lO, the first stage outer wall material 17 is engaged, and the upper end is fixed with nails 11.

Therefore, in order to form a new outer wall U, the above steps are repeated until the eaves are successively covered.

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 12 do not have a through structure,
It is also possible to use a short member.

(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 exterior wall, so the number of construction steps can be omitted, and the construction period can be significantly shortened. It has the characteristic that it will not cause any hindrance to residence during construction. 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, a cover material was fixed between the batten and the vertical rim, and a starter was fixed to the surface side of the vertical rim, so the gap between the vertical rims was blocked from the outside air, improving insulation and
It has the advantage of having a structure with excellent corrosion resistance. Furthermore, there is no need to fix the liner material as in the past, making construction easy and highly efficient. Further, when an outer wall is formed using the outer wall repair method according to the present invention, it becomes a double wall structure with an existing wall, and has the characteristic of becoming a wall structure rich in heat insulation, soundproofing, and fireproofing properties.
