Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention can easily and beautifully use an existing wall of a building having a mortar wall such as a large wall or a true wall as an outer wall by using a dry type outer wall material, and further, The present invention relates to an outer wall repairing method in which a new wall is provided with heat insulating properties, waterproof properties, humidity control properties, and dimension adjustment functions.

[Conventional technology]

Conventionally, in order to repair an outer wall exposed on the surface of a house or the like, in particular, a mortar outer wall, a method of removing all existing walls to be repaired or washing and forming a mortar wall again has been adopted. However, the wall to be renovated by this method has many processes and it was necessary to stop living. As a result, the cost is increased, the number of days is increased, and the heat insulating property, waterproof property, and workability are disadvantageous. There is also a construction method in which a new dry type outer wall material is directly constructed on the existing wall and repaired. However, in this case, since the surface of the existing outer wall is often uneven, the new outer wall is also uneven,
Not only is it difficult to apply, but it also has the drawback of having an ugly appearance. Furthermore, in this structure, the placement position of the outer wall material is unknown, and the storage around the base is not neat. In addition, since the existing mortar wall is considerably impregnated with water, there is a disadvantage that mold and the like are generated when the heat insulating material is simply laid and fixed.

[Object of the Invention]

In order to eliminate such drawbacks, the present invention lays and fixes a base material useful as a waterproof material, a humidity control material, and a cushioning material on the surface of an existing mortar wall, and a furring strip is horizontally or vertically placed on the base material. After installing the base part, the new outer wall material with heat insulating property is installed to make the existing mortar outer wall beautiful, and also with heat insulating, humidity control, and impact resistance. We propose a method for repairing outer walls that requires no skill.

[Structure of Invention]

Hereinafter, the outer wall repairing method according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a typical example of a repaired outer wall structure constructed by the construction method according to the above invention.
That is, in FIG. 1, 1 is an existing wall, which is composed of a main pillar 2, a stud 3, a wood lapping plate 4, a lath material 5, and a mortar wall 6. The structure of the existing wall 1 is composed of a large wall, a true wall, or one kind of base mortar wall as shown in Japanese Patent Publication No. 53-8129. Reference numeral 7 is a base, 8 is an anchor, 9 is a cloth foundation, 10 is a base material, which is a heat insulating material, has a waterproof property, a cushioning property, and a humidity controlling siding insulation board, a synthetic resin foam, (soft, hard. Polyurethane foam, polystyrene foam, polyisocyanurate foam, phenol foam, etc. 1
Made from seeds or higher), primarily to avoid appearing on the surface of the Lee existing wall 1 of the surface irregularities later a new wall, or leaked rainwater to existing wall 1 from Russia new outer wall, so that condensation does not occur C) It is for exhibiting a function of imparting heat insulating property and sound absorbing property to the existing wall 1 and preventing generation of mold. Its size is 900 x 1800 mm x 9 to 15 mm (thickness). 11 is a furring strip, which is a restraining material at a position corresponding to the main pillar 2 and the stud 3.
It is fixed to the main pillar 2 and the stud 3 from above with a nail 12 from above. Reference numeral 13 denotes a base drainer for mounting an elongated body having a cross section as shown in FIGS. 2 (a) to (d) in the vicinity of the base 7. Reference numeral 14 is a starter, which is particularly necessary when a new hook type outer wall material is to be installed horizontally, and is unnecessary for vertical installation. The starter 14 is either a metal fitting structure or a long type. 15 is a new outer wall material, which has a heat insulating property and has a male and female type connection structure,
And it is a long one. Specific examples are mainly shown in FIGS. 3 (a) to (q) and FIGS. 4 (a) to (p), and the structure is between the metal surface material A and the back surface material C. The core material and the heat insulating material B are integrally filled.

〔Example〕

Next, the outer wall repairing method according to the present invention will be described. First, in order to construct an outer wall rehabilitation wall as shown in FIG. 1 , a 900 × 1800 mm base material 1 is placed on the mortar wall 6 on the existing wall 1.
Lay and fix 0. At this time, either the main pillar 2 or the stud 3 should be installed at a position where the base material 10 is to be installed, or a guideline (not shown) is drawn on 900 mm or 450 mm, and one of them is the main pillar. The pillars 2 and the studs 3 are matched with each other. Next, the furring strip 11 on the base material 10, and
The main pillars 2 and the studs 3 are fixed vertically and sequentially through the nails 12 at positions corresponding to the main pillars 2 and the studs 3. Therefore, when the construction of the furring strip 11 is completed, the base drainer 13 is fixed in the horizontal direction near the base 7, so-called the lower end of the furring strip 11. Next, the starter 14 is fixed on the vertical portion of the foundation drainer 13, and a new outer wall material 15 as shown in FIG. 3 (f) is sequentially installed on the foundation from the foundation toward the eaves (not shown) by a hooking method. It is something to do.

[Other Examples]

What has been described above is only one example of the outer wall repairing method according to the present invention, and after the furring strip 11 is constructed, a synthetic resin foam having a thickness of the furring strip 11 is filled between the furring strips 11, and then the above-mentioned. The outer wall can also be renovated by constructing in the same manner as.

〔The invention's effect〕

As described above, the outer wall repairing method according to the present invention has a great feature that construction can be performed in a short time without requiring skill and without interrupting living. further,
The base material is characterized in that the outer wall having humidity control, breathability, waterproofness, heat insulation, soundproofing, impact resistance, and condensation resistance can be easily constructed. Further, there is an advantage that even if the surface of the existing outer wall is uneven, the surface of the new outer wall can be made to have a beautiful appearance.
