Abstract

PURPOSE:To facilitate execution of works by providing both a bed sheet layer which is formed while a plane mesh member is contained inside, and an exterior finishing surface layer which is integrally formed on one sheet surface of the sheet layer while being piled up. CONSTITUTION:A polyethylene sheet 2 is spread over a horizontal table 1, and a flexible mesh member 3 composed of chemical fibers and the like is placed thereon. In the second place, undercoating material 4 in an acryl emulsion system is applied on the upper surface of the member 3 while being pressed downward with a trowel T in such a way that the member 3 is covered by the undercoating material 4, so that a bed sheet layer 5 is thereby formed with the material 4 dried up. Following which, the sheet layer 5 is peeled off out of the sheet 2 while one end of the layer is being manually lifted up, and exterior finishing material is applied onto one surface of the sheet layer 5 by means of spraying, so that an exterior finishing surface layer 6 is thereby formed while imitation stone wall plates 7 are lined up so as to be bonded on the exterior finishing surface. By this constitution, exterior finish can thereby be provided in a simple manner.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an exterior panel used for the exterior wall surface of a building.

<Prior Art> Conventionally, there are the following methods for covering the exterior walls of buildings.

First, a primer is applied to the surface of the building's foundation.

After the base material dries, an exterior paint containing natural stone particles is sprayed on. Once the exterior paint has dried, the exterior treatment work is complete.

<Problems to be Solved by the Invention> However, in conventional exterior treatment methods, the spraying of coating materials is highly dependent on the weather. Also, some of the paint will scatter when spraying, so if there are buildings nearby, cover the area with a sheet before spraying.
It is necessary to prevent the coating material from scattering. Furthermore, when spraying the coating material, it is necessary to cover the parts (window glass, etc.) close to the area with a sheet to prevent the coating material from adhering.

Furthermore, when spraying the coating material onto the exterior wall surface, there is a drawback that the spraying may be uneven, no matter how skilled the person is.

Typical exterior spraying involves standing on a fixed platform, completing the spraying at the possible height, then moving to a lower (or higher) platform and moving to the next height. However, the boundaries between these height areas tend to stand out as horizontal lines.

In particular, in each height region, high areas are sprayed diagonally upward, low areas are sprayed diagonally downward, and the spray angles vary greatly at boundary areas, which tends to cause unevenness.

In view of the above circumstances, it is an object of the present invention to provide an exterior plate that can easily form an outer wall surface with a good appearance, and to provide a method suitable for manufacturing the exterior plate.

Means for Solving the Problems> The exterior plate according to the first invention comprises a planar mesh member and a base material formed of a synthetic resin emulsion coating material containing the mesh member inside. a sheet layer;
It is characterized in that it includes an exterior wall layer whose base material is a synthetic resin emulsion coating material which is integrally formed in a laminated state on one sheet surface of the base sheet layer.

When manufacturing this exterior board, it is necessary to apply the synthetic resin emulsion-based coating material to the mesh member and dry it so that the mesh member is contained therein. At that time, if the coating material is applied to each side of the mesh member and dried, the work efficiency is poor.

Furthermore, if a mesh member is placed on wood or the like and a coating material is applied, the mesh member and the wood or the like will adhere to each other when the coating material dries.

The manufacturing method for the exterior plate according to the second invention solves this problem, and includes the following steps.

A flat mesh member is placed on a synthetic resin sheet, and a base coating material based on a synthetic resin emulsion coating material is applied to the mesh member so that the mesh member is hidden inside the base coating material. A base sheet layer is formed by coating and drying. Further, an exterior coating material based on a synthetic resin emulsion coating material is attached to one sheet surface of the base sheet layer and dried to form an exterior wall layer. Further, after forming the base sheet layer or forming the exterior wall layer, the base sheet layer and the synthetic resin sheet are separated.

The exterior plate according to the first invention and the exterior plate obtained by the method of the second invention are formed by doubly adhering the coating material to the mesh member as described above, and the reason for this is as follows. That's right.

For example, if you want to make this exterior panel look like a stone wall, you can mix stone or other appropriate particles with the exterior coating material, but if you apply only the exterior coating material directly to the mesh member, Since the adhesion between the coating materials and between the mesh member and the coating material is weak, the strength of the exterior board is weakened. In addition, it is preferable to spray the exterior coating material to create a stone wall-like appearance, but if you spray the coating material directly onto the mesh member, it will be more difficult to apply the coating material between the mesh members than when applying with a trowel. The coating material will not fully penetrate into the surface, and the strength of the exterior panel will be weakened from this point of view as well.

Therefore, in the exterior plate according to the present invention, first, the mesh member is
A base coating material that is not intended for exterior use (that is, does not contain particles for exterior use) is applied and dried, and then an exterior coating material is applied by spraying or the like.

Function: This exterior board has a base coating material based on a synthetic resin emulsion coating material that hardens to include the mesh member inside, thereby forming a base sheet layer with sufficient strength. Ru. Further, an exterior coating material is attached to one sheet surface of the base sheet layer to form an exterior wall layer, thereby giving the appearance of the exterior wall of the building. Note that since both the base coating material and the exterior coating material are based on synthetic resin emulsion coating materials, the exterior coating material firmly adheres to the base sheet layer. Further, the back surface of the exterior wall layer is the sheet layer, which can be firmly bonded to the exterior wall of a building made of concrete or the like with an adhesive.

<Example> In conjunction with the description of an example of the manufacturing method according to the second invention, an example of the exterior plate according to the first invention will be described based on the drawings.

First, as shown in FIG. 1, a polyethylene sheet 2 is placed on a table 1 having a horizontal upper surface to form a polyethylene plane. A flexible mesh member 3 made of chemical fiber, natural fiber, glass fiber, etc. is placed thereon. An acrylic emulsion base coating material 4 is applied to the upper surface of the mesh member 3 by pressing it downward with a trowel T.

Then, as shown in FIG. 1, the coating material 4 enters between the meshes of the mesh member 3 and the back side of the mesh member 3 (between the polyethylene sheet and the mesh member), and the mesh member 3 is hidden in the coating material. state.

Then, when this coating material 4 is dried, a base sheet layer 5 (FIG. 2) is formed which uses the acrylic emulsion base coating material 4 containing the mesh member 3 therein as a base material.

Next, as shown in FIG. 2, the base sheet layer 5 is peeled off from the polyethylene sheet 2 by holding one end of the base sheet layer 5 by hand and pulling upwards. At this time, since the acrylic emulsion coating material 4 does not adhere to the polyethylene sheet 2 even when dried, the base sheet layer 5 can be easily peeled off from the polyethylene sheet 2.

Next, as shown in FIG. 3, an exterior coating material is sprayed onto one side of this base sheet layer 5. This exterior coating material is an acrylic emulsion resin coating material mixed with granite particles. When this dries, an exterior wall layer 6 is formed, and an imitation stone wall board 7 as an exterior board is completed.

This imitation stone wall board 7 can be used, for example, as follows.

The imitation stone wall board 7 is cut to the width and height dimensions of the stones used in constructing an actual natural stone wall, and they are aligned and pasted on the outer wall surface of the building. At that time, the mesh member 3
Since it is flexible, this imitation stone wall board 7 is also flexible and can be attached to a curved outer wall surface. This gives the appearance of a stone wall made of natural granite.

In this embodiment, the base sheet layer 5 is a polyethylene sheet 2.
Although the exterior coating material is sprayed after being peeled off from the surface, the order of both steps may be reversed.

Furthermore, when forming the base sheet layer 5, the base coating material 4 may be applied to one side of the mesh member 3, and then the mesh member 3 is turned over and the base coating material 4 may be applied to the back surface thereof.

Alternatively, the imitation stone wall board 7 may be manufactured from the beginning using a mesh member having the width and height dimensions of the stone materials used when constructing a natural stone wall, without cutting it later.

Furthermore, the exterior coating material 6 may contain not only granite particles but also Oya stone powder, marble particles, or other decorative particles such as synthetic resin.

Further, the base material for both the base coating material and the exterior coating material is not limited to an acrylic emulsion coating material, but various materials such as an epoxy emulsion coating material can be used.

Furthermore, the exterior coating material may be applied with a trowel or the like instead of spraying.

Further, the mesh member 3 does not necessarily have to be flexible, and may be made of a non-flexible material, for example, made of stainless steel wire, as long as it is dedicated to a planar outer wall surface.

Further, the synthetic resin sheet on which the mesh member is placed when manufacturing the exterior board is not limited to polyethylene, but may be a sheet made of other materials as long as the exterior coating material can be peeled off after drying.

It goes without saying that the present invention can be implemented with various other modifications based on the knowledge of those skilled in the art.

<Effects of the Invention> According to the exterior plate according to the present invention, the exterior can be easily provided by pasting this on the outer wall surface of a building with an adhesive.

Furthermore, this exterior board can be manufactured in a factory that is away from the outer wall of the building to which it is to be exteriorized, without being affected by the weather. Therefore, a considerable part of the work of forming the outer wall surface can be done without being affected by the weather.

Furthermore, there is no need to provide a sheet around the area to be exteriorized to prevent paint from scattering or adhering to nearby areas during exteriorization work. Additionally, there is no unevenness that occurs when the exterior coating material is sprayed directly onto the exterior wall surface, and the finished product is in good condition.

In addition, the core material of this exterior board is a mesh material, and both the base coating material and exterior coating material are synthetic resin emulsion-based coating materials, so this exterior board is breathable.

It has water permeability, and when this exterior board is attached to the exterior wall of a building, there is no possibility that rainwater will stay between the exterior board and the exterior wall for a long period of time, causing the exterior board to peel off from the exterior wall.

Further, according to the method for manufacturing an exterior board according to the present invention, the base coating material can be quickly applied to the mesh member so as to include the mesh member therein, and therefore the exterior board can be manufactured easily and efficiently. can do.
