水を発生する問題があつた。 In the case of external walls of buildings and structures, for example, when cement mortar walls develop over a wide range of cracks and peeling due to aging, the external walls must be removed and reapplied. This work required many days and man-hours and had the disadvantage of damaging the pillars and base plate. In addition, during the construction period, we will take precautions to prevent rain and wind from entering the building.
It was necessary to carry out other temporary construction work, which increased costs, and in severe cases, there were disadvantages such as having to cancel the residence. Furthermore, in order to save energy, conventional exterior walls lacked a heat-insulating structure, making them less comfortable to live in, and they also had drawbacks such as high heating and cooling costs. Moreover, when applying this type of heat insulation structure to a conventional outer wall, a method is known in which the space between the inner wall and the outer wall is filled with a heat insulating material. However, in this case, the entire wall would have to be demolished,
In addition to requiring a considerable amount of cost and man-hours, there were disadvantages in that the mortar wall was breathable, so the insulation deteriorated and it was difficult to distribute it uniformly. In addition, mortar walls have an uneven surface, so if a rigid exterior material is brought into direct contact with it, the finish and appearance of the wall will become uneven, which not only spoils the aesthetics, but also damages the appearance of new exterior materials. There was a problem with condensation water forming on the connecting part and the back side.

材を示すものである。 An embodiment of the exterior wall repair method according to the present invention will be described in detail below with reference to the drawings. Figure 1a,
b is a longitudinal and cross-sectional view showing an outer wall, for example a cement mortar wall, formed by the outer wall repair method according to the present invention, 1 is an existing outer wall, for example a cement mortar wall, and a cement mortar layer 2 and a lath 3 are shown.
It is composed of a waterproof layer 4, a lath board 5, and a main body 6 of a main pillar or stud. Reference numeral 7 denotes a mounting body such as a rim, a rim, or other mounts, which are fixed at appropriate intervals so as to be perpendicular to or parallel to the main pillar, for example. The mounting body 7 is made of one of wood, steel, synthetic resin, or a member having the same mechanical strength. The cross section of this mounting body 7 is square, trapezoidal, hollow pipe, T-shape, etc., and it is fixed with nails, screws, etc.
It is driven in such a way that it reaches the existing main pillars and studs through it. As is clear from the figure, this mounting body 7 prevents the adverse effect of the existing mortar wall with an uneven surface on the new wall surface 14a, thereby making the decorative surface of the new wall surface 14a more flush with the existing outer wall 1 and the new wall surface. A space 7a is formed between 14a,
It has insulation properties and helps prevent condensation from forming due to moisture permeation from inside the room. Reference numeral 9 denotes a base material which acts as a heat insulating board, a base board, a cushioning material, a reinforcing material and a moisture barrier layer, or a moisture absorbing material, and its structure is as shown in Fig. 2, which is attached to a hard base material 10, a heat insulating material 11, and the back side thereof. It is a plate body that is integrated with a sheet-like material 12, and its size is approximately 20 to 50 mm (thickness H) x 900 mm.
The standard is (width W) x 1800 mm (length L). Of course, it goes without saying that the size is not limited to this size. To explain further, the hard base material 10 of the base material 9 mainly functions as a reinforcing material, and specific examples thereof include one type of plywood such as plywood, gypsum board, wood wool cement board, slate board, etc. It consists of Further, the heat insulating material 11 is made of a synthetic resin foam, and it is desirable that this foam has compressibility of at least about 0.5 to 3 mm. Specific examples include polyurethane foam (soft and hard), polyisocyanurate foam, polystyrene foam, phenol foam, urea foam, polyethylene foam, and vinyl chloride foam. In addition, in order to integrate the hard base material 10 and the heat insulating material 11, the hard base material 10 may be integrated with the hard base material 10 via an adhesive, or the raw material for the heat insulating material 11 may be discharged in an on-site foaming manner and its self-adhesive property may be utilized. The synthetic resin foam layer may be formed simultaneously with the formation of the synthetic resin foam layer. Note that the heat insulating material 11 is provided so as to completely cover the front or back surface of the hard base material 10. Further, the sheet-like material 12 mainly has the function of preventing loads from being applied to the extreme parts of the waterproofing material, moisture absorbing material, and heat insulating material. Further, the sheet-like material 12 protects the heat insulating material 11 and further improves the strength of the base material 9 by forming it into a sandwich structure. Additionally, it has at least one secondary function, such as waterproofness (including moisture impermeability), water absorption to prevent dew condensation, and thermal radiation to improve heat insulation. The sheet-like material 12 is made of asphalt felt, tar felt, kraft paper, asbestos paper, or laminated with one or more of synthetic resin film and metal foil (which also has a radiation effect). Or, if necessary, it can be waterproofed. The base material 9 configured in this manner is fixed to the mounting body 7 by contacting the sheet-like material 12 via fixing tools 13 such as nails or screws. In this case, 3.03m 2 is 2
The base material 9 is coated with a sheet of base material 9. Unlike the so-called base of conventional lath board, it is highly efficient in construction. The siding material 14 is made of either metal or ceramic material, and its structure is that of the surface material 15 made of metal sheet material in the metal siding material.
A core material 16 is filled in the core material 16, and a sheet-like material 17 is stretched or pasted on the back surface of the core material 16. To explain further, the surface material 15 is formed from a male connecting portion 18, a female connecting portion 19, a decorative surface 20, and the like. The core material 16 may be made of synthetic resin foam (for example, polyurethane foam, polyisocyanurate foam, phenol foam, epoxy foam, polyethylene foam, or foam obtained by adding perlite, borax, etc. to these foams), rock wool, cellulose-based heat insulating material, or glass wool. It consists of one type. In addition, sheet-like material 17
It is made of one type of moisture-controlling kraft paper, cardboard, waterproof asphalt felt, or synthetic resin film. Note that the specific shapes are for metal-based siding materials as shown in FIGS. 3a to 3i and for ceramic-based siding materials as shown in FIG. 3j.

つた。 Next, to explain the exterior wall repair method according to the present invention, first, in order to form a new wall surface 14a with a cross section as shown in FIGS. 1a and 1b on the existing exterior wall 1 made of mortar wall, material 9, mounting body 7, metal siding material 14 shown in Fig. 3a
Assume that we use In addition, the thickness of the cent mortar layer 2 of the existing outer wall 1 is 20 mm, the plate thickness of the mounting body 7 is 21 mm,
Hard base material 10 is 9mm plywood, insulation material 11 is density 30
Kg/m 3 , polyurethane foam with a board thickness of 16 mm, and the product name for siding material 14 is Makabe (surface material 1
5 is a color steel plate with a thickness of 0.27 mm, the core material 16 is a polyurethane foam with the same specifications as above, and the sheet material 17
It is assumed that a sandwich structure made of kraft paper laminated with aluminum foil and having a total thickness of 15 mm is used (manufactured by IG Kogyo Co., Ltd.). Therefore, we decided to install the mounting body 7 on the existing outer wall 1 as a horizontal frame with a height of 450 mm.
It is fixed to the main body 6 such as the main pillar or stud of the existing exterior wall 1 with nails 8 at a pitch of 1/4 inch. Next, attach the base material 9 to the mounting body 7.
A sheet-like material 12 is laid and fixed in contact with the top, and a space 7a is formed between the surface of the existing outer wall 1 and the base material 9. In particular, the sheet-like material 1 of the base material 9 is placed on the mounting body 7.
The reason why the two surfaces were brought into contact was to prevent indoor and outdoor air and moisture from permeating, and to suppress shock and vibration from the existing outer wall 1 by the cushioning properties of the heat insulating material 11.
And when the unevenness on the surface of the existing outer wall 1 cannot be absorbed by the mounting body 7 alone, it is deformed to absorb it so that the base of the new wall surface 14a becomes flat. Next, a siding material 14 is vertically fixed to the mounting body 7 via nails 8 on the surface of the base material 9, the so-called hard base material 10 surface, to form a new wall surface 14a. In addition, in FIGS. 1a and 1b, the two-dot chain line indicates the interior material. And the existing outer wall 1
The overall structure is 4mm plywood for the interior, 5mm lath boards, and 15mm cement mortar walls. Therefore, a new wall surface 1 is added to this existing outer wall 1 and the existing outer wall 1.
Comparing the heat transmission coefficient with the wall forming 4a, the former is 2.02kcal/m 2 h℃, while the latter is 2.02kcal/m 2 h℃.
It was 0.44 kcal/m 2 h°C, and the difference in performance was remarkable.
