Description

TECHNICAL FIELD The present invention relates to a construction method for repairing an outer wall of a building or a building, for example, a prefabricated outer wall formed by a mortar wall or a tile wall.

(Prior Art) Conventionally, Japanese Patent Publication No. 58-17869 is known as this type of construction method. That is, the foundation bone is vertically extended on the outer wall made of dry outer wall material and extends to the draining end of the existing outer wall, and the liner material is fixed horizontally to the base directly or through the attachment base. The start material is fixed to this liner material, the first step of the new outer wall material is attached, and the outer wall is renovated by sequentially forming the roof.

(Problems to be solved by the invention) In the above-mentioned construction method, since the base bone is not fixed to the base, the stability is poor, and the starting material protrudes outward from the base and the base bone protrudes from the prefabricated outer wall. There is a big difference between the dimensions and it becomes difficult to construct,
There was a disadvantage that spoiled the appearance. Further, since the cut surfaces of the liner material and the starting material are exposed to the outside air and exposed to wind and rain, the liner material and the starting material have a disadvantage of corroding. Further, there is no disadvantage that the base part is not contained, that is, there is no so-called drainage of the base, so that the base is not heavy.

(Means for Solving the Problems) In order to solve such a drawback, the present invention provides a foundation drainer formed in a pipe-shaped cross section horizontally with respect to the lower end of an existing outer wall directly through a nail, and the existing drainer. It is fixed to the base of the outer wall from the mortar wall surface, and as a starting material, it is composed of an elongated engaging part for engaging the new outer wall material and an attaching part for contacting the surface of the existing outer wall. , The mounting portion is fixed to the skeleton, the new outer wall material is engaged with the starter, and the outer wall materials are sequentially engaged and fixed on the existing outer wall toward the upper side to form the new outer wall.

(Operation) Unlike the conventional wood, the foundation drainer covers the lower end of the existing wall with a uniform material, and the starter can be installed with the upper end of the foundation drainer as a guide, and also forms an opening between the existing outer wall and the new outer wall. It is to prevent.

(Example) Hereinafter, one example of the outer wall repairing method according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a repairing method according to the present invention, and FIG. 2 is an explanatory view showing a base portion of the repairing method according to the present invention, in which 1 is a skeleton of an existing wall, for example, a stud, 2 is an existing Mortar wall (hereinafter, simply referred to as wall) structure. To explain further, the wall 2 is on the outer surface of the body 1,
For example, it has a mortar wall structure constructed by laminating wood, a waterproof sheet, a lath sheet, and a mortar wall material in this order. 3 is a foundation, 4 is a base, 5 is a base drainer which is horizontally arranged at the lower end of the wall 2 and fixed to the base 4 via the wall 2. Mainly the lower end of a new outer wall material described later. Protective materials, accessories,
It functions as a guide and an engaging portion of the starter.
To explain further, the base drainer 5 is an elongated body and is shown in FIG.
As shown in (a) to (f), a metal plate and a plastic plate are molded. That is, the base drainer 5 is composed of a mounting portion 6, a draining portion 7 and a main body portion 8. The mounting portion 6 projects upward from the upper end of the inner wall 8a of the main body portion 8 and the inner end of the upper surface 8b of the main body portion 8 to the inner wall 8a. Is formed integrally with the wall 2 and is fixed to the base 4 via a nail 15 by abutting on the surface of the wall 2. The drainer 7 drains the lower end of the new outer wall, and may also serve as the lower end of the outer surface of the main body 8 (see FIGS. B and c). Further, the main body 8
Is hollow and mainly functions as a reinforcing material and a decorative material for the base drainer 5 . Reference numeral 9 is a starter, which is a hook portion that engages with the mounting portion 6 of the base drainer 5 , or a vertical portion 10 having a bent piece 10a and a storage groove 11 for storing the lower end of a new dry outer wall material 14.
And an engaging portion 12 for engaging the first step of the new outer wall member 14. The shape is, for example, as shown in FIGS. 4 (a) to (f), (a) to (c) are hooking type, and (d) to
(f) is a drop-in type starter for engaging the outer wall.
The starter 9 may be formed in a piece according to the purpose. Further, the new outer wall material 14 is a composite panel in which a plastic foam is interposed between a long surface material and a back surface material as shown in FIGS. 5 (a) to (k), and at the end of its connecting portion. It has a male and female type connection part, and it is either a hook type or a drop type depending on the type. Reference numeral 16 is a waterproof and cushioning waterproof sheet, and the wall 2 and the new outer wall material 14
The problem of the contact degree is suppressed, and the release of water from the wall 2 is prevented to eliminate the adverse effect on the new outer wall material 14. Of course, the waterproof sheet 16 is provided as needed.

Next, one embodiment of the outer wall repairing method according to the present invention will be described in detail. Now, in the prefabricated wall structure as shown in FIG. 1, the base draining 5 as first shown in Figure 2 wall 2
It is arranged horizontally at the lower end of and is fixed to the base 4 by nails 15. Next, at the upper end of the mounting portion 6 of the base drainer 5 ,
A plurality of starters 9 are attached to the positions where there are, and if necessary, fixed to the body 1 via nails 15. Next, starter 9
The new outer wall material 14 shown in FIG. 5 (c) is engaged with the
It fixes to the skeleton 1 through 5, and the construction of the new outer wall material 14 of the first step is completed. Next, the female connecting portion of the new outer wall material 14 of the second stage is engaged with the male connecting portion of the first stage, and the construction of the outer wall material of the second stage is completed. Therefore, in order to form the new outer wall 13, the above steps may be sequentially and repeatedly performed. Well-known accessories are used to store the eaves, projecting corners, entering corners, windows, and the boundary with the small wall.

The above description is merely one example of the outer wall repairing method according to the present invention, in which the hook portion 10a of the starter 9 is removed to form a simple end face, and the bottom portion of the storage groove 11 is drained to the base drainer 5 during construction. It is also possible to abut the upper surface of the part 7 and then fix it to the body 1 via the nails 15.

(Effect of the invention) As described above, according to the outer wall repairing method of the present invention, it is not necessary to dismantle the existing outer wall, so that it is possible to omit man-hours for construction, and it is possible to significantly shorten the construction period. It has the feature that it does not hinder living during construction. Furthermore, in the vicinity of the base, a pipe-shaped lightweight and beautiful base drainer that has the function of a liner material and a drainer instead of the conventional wood liner material, the function of a decorative material is fixed, so there is a linear body, a three-dimensional effect, It has a characteristic that it is a beautiful, waterproof and corrosive base material. In addition, in construction, it is sufficient to construct a drainage base on the wall, fix the starter on it, and to construct a dry outer wall material that will become a new outer wall, easy to construct and inexpensive There is. Further, when the outer wall is formed by the outer wall repairing method according to the present invention, it becomes a prefabricated wall and a twenty-wall structure, and the heat insulating property is
It has a soundproof and fireproof wall structure. Further, the lower end of the new outer wall material is covered by the drainage of the foundation, and the aesthetic appearance and the corrosion resistance of the lower end of the new outer wall material are improved.
