When constructing a plaster wall, first, after constructing a plaster wall underlayer, the plaster wall is coated with a plaster wall material to perform the construction. A wide variety of methods are known as construction methods for the painted wall foundation, and when the methods and problems are listed, usually, a metal lath or wire lath is spread on the foundation plate and cement mortar is often applied. This method has problems that the construction period is long, cracks are likely to occur, and thin coating cannot be performed.

There is a method in which a gypsum board is used as a base material, and a base adjustment coating material whose main raw material is gypsum plaster for board is thinly applied to the base material. Also, when using gypsum board, cracks are likely to occur at the joints between adjacent boards, so it is necessary to take measures to prevent the cracks, but since gypsum board does not have too many stables and nails, the joints are fibrous. The net must be attached with a coating material one by one, which makes the work difficult.

There is a wall base material that is made by coating a wood-based plywood with a coating material mainly composed of cement and lime in advance, but it is difficult to perform on-site processing according to the wall surface, special tools are required, and incineration of the remaining material cannot be performed. As a result, the cost becomes high economically.

When a plaster lath board is used and a ceiling coating is applied on it using a plaster plaster for board as a main raw material, the gypsum lath board is softened by the dew condensation phenomenon, and the thick paper on the surface is There is a problem in that the surface of the plaster plaster for board may be cracked or peeled off to cause a problem such as cracking or peeling, so that it can be used only for a small-scale ceiling.

In addition, plywood, pulp cement board, wood wool cement board, etc. are used for the base plate, and a base adjustment coating material may be applied to this, and mortar finishing, cement-based spray finishing, etc. may be performed. There was a problem that the effect of joining and joining was weak.

The present invention was devised in order to address the above-mentioned various problems, and the purpose is to prevent the coating wall material from peeling off, to prevent cracks from occurring, and to withstand vibration and impact. It is intended to provide a painted wall construction method and a painted wall base material used for the construction method.

That is, when roughly classified, a through hole drilling step, a base adjusting material applying step, a base material disposing step,
It consists of four steps of coating wall coating. Then, each step will be specifically described below with reference to FIGS.

(Through Hole Drilling Step) In this step, a plate body 2 serving as a base material for forming the painted wall base material 1 is formed.
Is a step of forming a plurality of through holes 3, 3 ,.

That is, a veneer plywood having a thickness of about 6 mm is used as the plate body 2, and a through hole 3 having a diameter of about 10 mm is formed in the plywood.
Is a step of boring so that the space between them is about 50 mm. The size of the plywood is preliminarily formed into a predetermined size by cutting or the like by a frame or the like in a building,
A plurality of through holes 3 are formed in this (see FIG. 2). Normally, the size of plywood is 910 mm long and 1820 m wide.
The size of m is used, and the through hole 3 formed in the plywood need not be a circular hole, but may be a triangular hole, a square hole, or the like. However, from the viewpoint of strength, it is preferable that the size of the holes has a constant shape and that the distance between the holes is also kept constant. Then, when the plate body having the shape is used, about 450 through holes are formed.

Here, the plate body 2 serving as the base material is not limited to the veneer plywood (three-ply plywood), and a single plate body or a resin plate may be used. However, considering the degree of expansion,
Plywood is preferred.

(Undercoat adjusting coating material applying step) In this step, the undercoat adjusting coating material 4 is applied to the surface of the plate body 2 having the through holes 3, 3 ... In this step, the back surface adjusting coating material 4 is projectedly engaged with the back surface 6 of the plate body 2 through the through hole 3.

That is, as the undercoat adjusting coating material 4, a material in which cement and lime are main raw materials and cement-based polymer dispersion or the like is mixed is used, and this is applied to the surface of the plate body 2 forming the undercoat material 1 by 3 to 4 mm. It is applied to a thickness to form a coating wall foundation layer 5 of the foundation adjustment coating material 4 on the surface, and the base adjustment coating material 4 is passed through the through holes 3, 3 ,.
To form a coating material engaging portion 7 (second
(Refer to the drawing), which is a step for integrating the plate body 2 and the painted wall base layer 5. The coating material engaging portion 7 is a base adjustment coating material 4
Of the base adjusting coating material 4 at the protruding portion from the back surface 6 of the plate body 2 of
It is formed by the outflow and solidification of, and usually has a length of 3 to 15 mm. However, this length is arbitrary and the plate 2
Any shape may be used as long as the coating wall base layer 5 and the coating wall base layer 5 are firmly integrated. Further, the coating wall base layer 5 made of the base adjusting coating material 4 may be formed in a multi-layered structure, if necessary.

By the way, in applying the undercoat adjusting coating material 4 from the front surface of the plate body 2, if the undercoat adjusting coating material 4 is applied with a coating thickness of about 1 to 3 mm, the back surface 6 of the plate body 2 through the through holes 3, 3 ,. A coating material engaging portion 7 of about 3 to 15 mm from which the base adjustment coating material 4 projects is formed on the plate body 2 to integrate the base adjustment coating material 4 with the surface of the plate body 2 It acts so as to form the coating wall base layer 5 which is filled with the base adjustment coating material 4 in a sufficient state and has a leveled surface without sagging. Therefore, it becomes possible to finish various coatings thinly in the coating wall application step described later, for example, a thin coating finish of about 5 to 10 mm from the plate surface to the coating (painting wall) surface (coating thickness). It has the advantage of being possible.

(Substrate disposing step) In this step, the coating wall foundation material 1 obtained by integrating the coating wall foundation layer 5 on the surface of the plate body 2 is mounted on the wooden frame of the building with a stainless steel spiral nail. It is a step of firmly attaching and forming the base of the painted wall. Incidentally, this step is performed before forming the coating wall base layer 5 on the surface of the plate body 2, if necessary, in other words, in the state of the plate body 2 having the through holes 3, 3 ... It is also possible to firmly attach it to the wooden frame with a stainless steel spiral nail, and then form the painted wall base layer 5.

(Coating Wall Coating Step) In this step, the coating wall base layer 5 of the coating wall base material is surface-coated with a coating wall material (paint). That is, in the step of constructing the painted wall 9, as the painted wall material (paint), ordinary mortar or other material is used. However, a finishing method other than coating may be adopted. For example, a cement-based spray finish, an organic-based spray finish, or the like may be adopted.

In addition, when performing this process, normally, it applies after applying the intermediate coating material 8 on the surface of the coating wall foundation layer 5. The adhesion of the coating wall 9 to the base material 1 is usually about 3 to 5 kg / cm ² . However, the adhesive force may be higher than that.

Then, with respect to the wall in the building constructed through the above-mentioned process, when the shape weight of 1 kg is projected from the base material of the painted wall when protruding from a distance of 1.5 m and a crack phenomenon is examined, it is completely peeled and No crack was observed. On the other hand, the base adjustment coating material 4 is fixed by the through hole 3,
The peeling phenomenon was observed in the same test using the base material in the non-integrated process. Further, in the case of the example, no peeling phenomenon was observed even in the durability test for 3 years, and the same result was obtained when it was used as a ceiling wall.

Next, the structure of the painted wall base material 1 used in this embodiment will be described more specifically.

As shown in FIGS. 2 to 4, the painted wall base material 1 is composed of a plurality of
A state in which the acrylic latex polymer diluent is applied and dried on the wood-based plywood 2 coated with or impregnated with the phenolic resin in which the through holes 3, 3 ... Consisting of about 8 mm are formed at intervals of about 50 mm ( Preferably, within one week), a surface adjusting coating material [JIS-6916 (cement-based surface adjusting coating material)] 4 is applied to the surface thereof, and the surface adjusting coating material 4 has a plurality of through holes 3, 3. · Through wood plywood 2
The coating material engagement portion 7 is formed by projecting 3 to 15 mm (more or less) on the back surface 6 of the, and the coating wall base layer 5 is integrated with the wood plywood 2 and the surface thereof is coated. It has a structure that allows construction of walls. The base adjusting material engaging portion 7 may have a dumpling-like configuration as shown in FIG.

A lime-based coating material such as plaster can also be used as the base adjustment coating material 4. In this case, there is an advantage in that it is not necessary to hit a lowering tab such as Manila hemp for preventing peeling and cracks which has been conventionally used.

By the way, in the above-mentioned embodiment, the plate forming the base material is described as a wood-made plywood having a thickness of about 5 mm using a phenol resin, but it may be configured by other kinds of plate, for example, You may use the thing with the thick thickness. That is, in the case of the present invention, the plate forming the base material has a through hole, in other words, a perforated plate, particularly a perforated plywood,
A base adjusting material (base adjusting coating material) is fixed on the back surface of the plate body through the hole, and the plate body and the base adjusting material (base adjustment coating material) are fixed.
