Description

TECHNICAL FIELD The present invention relates to an outer wall structure in which a skeleton for new construction or renovation is used as a base, and an outer wall having an air cycle function and an insect repellent function is formed on the skeleton.

[Conventional technology]

Conventionally, for example, in order to repair an outer wall of a building or a structure, a method of removing all existing walls to be repaired or cleaning and forming a mortar wall again has been adopted. In addition, Japanese Patent Publication Sho 58-
No. 17869 is also known. In addition, the outer wall of the new construction has a structure in which asphalt felt is placed on the entire surface of the main body, studs, etc., and the outer wall material is simply fixed on this felt or on the furring strip fixed on the felt. there were.

[Problems to be solved and used by the invention]

However, in the structure where the outer wall was renovated by this kind of method,
The former has the disadvantage that it is necessary to stop living, and the man-hours, days, and cost become enormous. Also, in the latter case,
The number of days is about one week, but the maintenance cost is high because it has to be repaired once every five years. Furthermore,
No air cycle was performed between the old and new walls of No. 58-17869, which had the disadvantage of lacking energy saving, humidity control, and habitability improvement. Further, in the conventional newly constructed outer wall, although a void is formed between the furring edges, this space only has a function as a heat insulating layer and does not have an air cycle function.
Further, in this kind of structure, there is a possibility that a path between the body and the outer wall material may become a path for a rat or a nest of harmful insects, and the environment is deteriorated, which is not preferable for hygiene.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has an upper end opening formed by an outer wall material fixed on a vertical furring strip, and a pest control,
Protective nets and toes, lower end openings are formed by insects, protective nets and battens, and drainage on the base, and by creating a structure in which the void between the vertical furrows communicates with the attic, it has an air cycle function and pests. We propose an outer wall structure that prevents invasion of mice, improves environmental hygiene, and prevents deterioration of the body.

〔Example〕

An embodiment of an outer wall structure according to the present invention will be described below in detail with reference to the drawings. That is, the first
The figure shows an example of a base portion when the above-mentioned invention is applied to an existing mortar wall. In the figure, reference numeral 1 denotes an existing outer wall including a main pillar 2, a stud 3, a lapping plate 4, a lath material 5, and a mortar wall 6. It consists of The structure of the existing outer wall 1 is a large wall, a true wall, or a base mortar wall as shown in Japanese Patent Publication No. 53-8129, a concrete wall not shown, or glass wool, cellulose fiber between the interior material and the exterior wall material. It also includes existing walls filled with rock wool or plastic foam (for example, a mortar wall on a base plate with a plywood subbed instead of lath). 7 is the base, 8
Is an anchor, 9 is a cloth foundation, and 10 is a vertical furring strip, which is substantially vertical from the base to the eaves, corresponding to the main pillars of the existing outer wall 1 , the studs 2 and 3, or as shown in FIG. The vertical furring strip 10 is either constructed after the 10a is interposed, and mainly functions as a mounting member for an outer wall member 14 and a material for forming an air cycle void, which will be described later. In particular, the mounting at the base portion is such that the lower end of the existing outer wall 1 exists as shown in FIGS. 3 (a) and 3 (b), or the lower end of the existing outer wall 1 extends to a region covered by a drainer described later. A batten 11 is horizontally fixed to the lower end of the vertical furring strip 10 and functions as a guide or a mounting member for the foundation drainer 12. The base drainer 12 is fixed as shown in FIGS. 3 (a) and 3 (b) to protect the base 7, the lower ends of the vertical furring strips 10 and the batten 11, and also functions as a decorative material. Reference numeral 13 is a starting material which is fixed horizontally as shown in FIGS. 3 (a) and 3 (b). The start material 13 differs depending on the shape of the outer wall material 14, particularly the shape of the connecting portion, and the start material 13 corresponding to each outer wall material 14, for example, FIG.
It is composed of one kind of a long body and a short body as shown in (c). As shown in FIGS. 5 (a) to (l), the outer wall material 14 is one of a heat insulating metal siding material and a ceramic siding material.
It consists of seeds. Reference numeral 15 is an outer wall, and 16 is an air cycle path, which is a space defined by the vertical furring strip 10 between the existing outer wall 1 and the outer wall 15 , and has an opening 17 formed on the base 7 side.
Reference numeral 18 denotes a toe, which functions as a cover material and a decorative material by covering the upper end of the outer wall material 14 at the eaves roof 19 portion as shown in FIG. Reference numeral 20 denotes a vent hole, which cuts out the eaves heaven 19 at the upper end of the vertical furring strip 10 and communicates with the air cycle path 16 between the vertical furring strips 10 to guide outside air into the attic space α and to provide an air cycle function to the wall. It is provided in the body to prevent moisture from deteriorating the house and to take in fresh air to discharge polluted air inside the house to the outside to improve the living environment inside the house. Numeral 21 is an insect repellent or protective net, which is a wire net, a net made of synthetic resin, or a structure that has a valve function and opens to take in air during the air cycle. It is intended to prevent damage to 16. Further, 22 is a nail or the like for attaching each component. In addition, as shown in FIG.
The caulking material 23 can be planted in the contact portion with the 18 to improve the airtightness.

Next, the construction method will be briefly described.

First, in order to form the outer wall repair wall as shown in Fig. 1,
Confirm the positions of the main pillars 2 and the studs 3 on the surface of the mortar wall 6 of the existing outer wall 1 or use position display means such as guidelines (not shown). Next, as shown in FIG. 3 (a) and FIG. 6, insect repellents and protective nets as shown in FIG. 7 (a) to (d).
21 is provided, and the vertical furring strip 10 is fixed vertically on the existing outer wall 1 and at positions corresponding to the main pillars 2 and the studs 3 with nails 22 or the like. Next, the batten 11 is horizontally fixed to the lower end of the vertical furring strip 10, and the base drainer 12 is attached to the vertical furring strip 10 as shown in FIG.
As shown in FIG. After that, the starting material 13 is horizontally fixed as shown in FIG. 3 (a), and then the tongue 18 is fixed by abutting against the eaves roof 19 as shown in FIG. After that, the outer wall material 14 is sequentially constructed from the base side toward the eaves heaven 19 to form the outer wall 15 . In addition, vent 20
Is to be drilled before attaching the outer wall material 14.

〔The invention's effect〕

As described above, according to the outer wall structure of the present invention, it is possible to perform construction without requiring skill, in a short time, and in the case of renovation, without interrupting living. Since the air cycle path that connects the base to the back of the hut is formed, the contaminated air inside the house is replaced by the inflow of fresh air, which improves habitability, mold resistance, corrosion resistance, and moisture resistance, and prevents deterioration of the house. Can be achieved. With insect repellent and protective net, insect damage and rat damage are eliminated, the environment inside the house can be improved, and the air cycle path is not closed by nests such as insects and mice. Battens make the base part more beautiful and secure. There are effects and features.
