Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall surface finishing plate sticking method for sticking a finishing plate member such as a tile or a flat stone sliced natural stone to a wall surface.

[0002]

2. Description of the Related Art When a finishing plate of this type is attached to a wall surface, if the wall surface is strong, the finishing plate is attached using mortar.

On the other hand, ALC which has become widespread in recent years
Lightweight walls made of boards, hollow cement boards, calcium silicate boards, etc. are not as robust as concrete, and often change due to changes in temperature and humidity. If you use mortar to attach a finishing board to this lightweight wall,
Since the wall dislocation spreads through the mortar to the finished board, the finished board may be damaged or separated from the wall and dropped.

In order to prevent such a situation, for example, "Method for surface treatment of concrete skeleton" is disclosed in Japanese Patent Publication No. 2-61.
No. 584. Here, in consideration of the differential movements caused by thermal expansion and contraction, that is, different movements of the wall and the surface finish material, a fiber sheet having a three-dimensional network structure is sandwiched between the wall and the surface finish material. This fibrous sheet absorbs the stress between the wall and the surface finish and prevents the surface finish from peeling.

[0005]

However, the above-mentioned conventional surface treatment method is such that even if the surface finishing material such as mortar or plaster is sufficiently prevented from cracking and peeling off, the finishing plate material such as tiles and flat natural stones. It was not possible to reliably prevent damage and peeling of the. This is because the fiber sheet having a three-dimensional network structure cannot sufficiently absorb the stress between the wall and the surface finish material, and compared with mortar and plaster, finishing of tiles, flat natural stone materials, etc. This is because the plate material is inferior in strength or adhesion. In particular, in recent years, the plate material of natural stone sliced very thin for weight reduction is damaged by a slight stress, so if such a plate material is attached to a lightweight wall surface by a conventional method, , The durability was significantly deteriorated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for attaching a finish plate material on a wall surface, which can surely prevent damage or peeling of a finish plate material such as tiles or flat stones.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a first adhesive is applied to a wall surface, a three-dimensional mesh non-woven cloth is attached to the wall surface, and an elastic body is obtained by curing. A second adhesive to be applied is applied to the three-dimensional mesh non-woven fabric, and a finishing plate material is attached.

Further, the first adhesive is permeated into the three-dimensional mesh non-woven cloth to approximately the middle of the thickness of the three-dimensional mesh non-woven cloth, and the second adhesive is applied to the other half of the thickness of the three-dimensional mesh non-woven cloth. Impregnated into a non-woven cloth.

Furthermore, the second adhesive is dispersed and applied at a plurality of positions with appropriate intervals.

[0010]

According to the present invention, the first adhesive, the three-dimensional mesh non-woven cloth, the second adhesive, and the finishing board are sequentially laminated on the wall surface. The three-dimensional non-woven fabric has flexibility, and the second adhesive cures into an elastic body. Therefore, the stress caused by the wall deviation is sufficiently relieved by the three-dimensional non-woven fabric and the second adhesive, and hardly acts on the finished board material.

Further, the first adhesive is permeated to approximately the middle of the thickness of the three-dimensional mesh non-woven cloth, and the second adhesive is permeated to the remaining half of the thickness of the three-dimensional mesh non-woven cloth. The three-dimensional non-woven cloth and the second adhesive are firmly adhered to each other.

Furthermore, the second adhesive is dispersed and applied at a plurality of positions with an appropriate interval. Therefore, the second adhesives at the respective locations are in sufficient contact with the air and dry or react with moisture contained in the air to be rapidly cured. Further, even if water droplets are generated between the three-dimensional mesh non-woven cloth and the second adhesive, the water droplets pass through between the second adhesives at each location and flow downward.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 to 9 show an embodiment of a method for sticking a finishing plate material according to the present invention. With reference to these drawings, a procedure for attaching an extremely thin sliced natural stone finishing plate to an ALC plate will be described.

First, each A forming a wall as shown in FIG.
The surface of the LC plate 1 is cleaned to remove dust, oil, water and the like, and then the polymer cement adhesive 2 is applied. The polymer cement adhesive 2 may be appropriately selected from various types of polymer cement adhesives that are commercially available. Further, in order to apply this polymer cement adhesive, any of a brush, a roller, a trowel, a spray, etc. may be used.

Before the polymer cement adhesive 2 dries, a three-dimensional mesh non-woven cloth 3 is attached as shown in FIG. The three-dimensional mesh non-woven cloth 3 is preferably a non-woven cloth made of synthetic resin fiber, carbon fiber, glass fiber, asbestos fiber or the like having alkali resistance and water resistance, or may be a composite of woven cloth and non-woven cloth. Absent.

When the three-dimensional non-woven fabric 3 is attached, an appropriate pressure is applied by the roller 4 so that the polymer cement adhesive 2 permeates into the interstices between the fibers of the three-dimensional non-woven fabric 3. This state is shown in FIG. 3, and the polymer cement-based adhesive 2 has penetrated into the three-dimensional mesh non-woven cloth 3 to approximately the middle of the thickness of the three-dimensional mesh non-woven cloth 3.

At this time, a small amount of the polymer cement adhesive 2 also oozes out on the surface of the three-dimensional mesh non-woven cloth 3. Therefore, many fibers 3a on the surface of the three-dimensional mesh non-woven cloth 3 adhere to the roller 4, and the three-dimensional mesh non-woven cloth 3 fluffs.

After the polymer cement adhesive 2 is dried, as shown in FIG. 4, the elastic adhesive 5 is vertically elongated and repeatedly applied at appropriate intervals. This elastic adhesive 5 has elasticity permanently even after being cured.
The elastic adhesive may be an epoxy polymer, a silicone polymer, a urethane polymer, a synthetic rubber polymer, or the like, but if it is a one-component polymer that cures due to the moisture contained in the air, this polymer is filled. It is excellent in workability because it only squeezes the tube 6.

Further, by stretching a thread coated with black ink and pressing this thread against the surface of the three-dimensional mesh non-woven cloth 3 (inking work), a plurality of lines are drawn vertically at appropriate intervals. Then, if the elastic adhesive 5 is applied along these lines, the work can be rapidly advanced.

FIG. 5 shows a cross section when the elastic adhesive 5 is applied to the three-dimensional mesh non-woven cloth 3. As shown in FIG. 5, the elastic adhesive 5 has penetrated into the three-dimensional mesh non-woven cloth 3 up to the remaining half of the three-dimensional mesh non-woven cloth 3 in which the polymer cement adhesive 2 has already penetrated almost halfway. Further, a large number of bristles on the surface of the three-dimensional mesh non-woven cloth 3 have penetrated into the elastic adhesive 5. This allows the elastic adhesive 5
Are firmly adhered to the ALC plate 1.

Here, it is difficult to completely clean the outer wall of the ALC plate 1, the hollow cement plate, the calcium silicate plate, or the like.
Oil and water remain. Therefore, when the elastic adhesive 5 is directly applied to the outer wall, the elastic adhesive 5 is easily peeled off. On the other hand, as in this embodiment, the polymer cement adhesive 2 is applied to the entire outer wall surface, and then the three-dimensional mesh non-woven cloth 3 is attached, and the elastic adhesive 5 is applied to the three-dimensional mesh non-woven cloth 3. In that case, the elastic adhesive 5 is firmly adhered, and peeling of the elastic adhesive 5 is less likely to occur.

Moreover, by sticking the three-dimensional mesh non-woven cloth 3 on the entire outer wall, the unevenness of the outer wall is reduced, so that the workability after this is improved.

If the unevenness of the wall surface to which the three-dimensional mesh non-woven cloth 3 is attached is within 3 mm, the height of the elastic adhesive 5 is 5
Raised to about mm, and unevenness on the wall is 3 mm to 6 mm
In that case, the height of the elastic adhesive 5 is set to about 10 mm. Further, if the unevenness of the wall surface exceeds 6 mm, the material and application method of the elastic adhesive are changed as described later.

Next, as shown in FIG. 6, before the elastic adhesive 5 dries, each finishing plate material 7 made by thinly slicing natural stone material is pressed against the elastic adhesive material 5 on the wall surface to finish these finishing plate materials. Stick 7. Since the elastic adhesive 5 is raised as described above, a gap is formed between each finishing plate 7 and the wall surface. Therefore, the surface positions of the finished plate materials 7 can be aligned by appropriately pressing the finished plate materials 7. In order to hold the surface position of each finished plate material 7 until the elastic adhesive 5 is cured, a plate piece 8 may be attached to a corner of each finished plate material 7 by a double-sided adhesive tape as shown in FIG. Further, in order to make the joint widths of the finished plate materials 7 uniform, a plate piece having a constant thickness or a rod having a constant diameter may be sandwiched between the finished plate materials 7.

Further, since a gap is formed between each finishing plate member 7 and the wall surface, the elastic adhesive 5 (polymer of one liquid) comes into contact with the air between each finishing plate member 7 and the wall surface, and the moisture contained in this air causes , Cures quickly.

On the other hand, prior to attaching the finishing plate material 7 to the wall surface, the primer 11 is previously applied to the back surface of the finishing plate material 7 by the roller 9 as shown in FIG. 8, and the primer 11 is dried. The primer 11 is applied to a position on the back surface of the finishing plate 7 to which the elastic adhesive 5 adheres, and the finishing plate 7 and the elastic adhesive 5 are applied as shown in FIG.
Intervene between. As a result, the finishing plate material 7 is firmly adhered, and the finishing plate material 7 is prevented from being contaminated by the elastic adhesive 5.

The primer 11 is, for example, a polyisocyanate-based, polyurethane-based or polyacrylate-based synthetic resin paint, and is preferably one that dries in a short time.

Contamination of the finished plate material 7 by the elastic adhesive 5 takes one day or more until the elastic adhesive 5 dries, so that the components of the elastic adhesive 5 permeate into the finished plate material 7 during this period. This is to exude to the surface of the finished plate material 7 and cause discoloration or alteration of the finished plate material 7. In contrast,
Since the primer 11 dries in a short time, the solvent of the primer 11 does not penetrate into the finishing plate material 7.
The coating of the primer 11 is interposed between the elastic adhesive 5 and the finishing plate material 7 to block the components of the elastic adhesive 5.

Since some elastic adhesives do not contaminate natural stone materials, application of a primer can be omitted when using this.

In this way, the polymer cement adhesive 2 is applied to each ALC plate 1, the three-dimensional mesh non-woven cloth 3 is applied, and after drying, the elastic adhesive 5 is applied to form each finishing plate material 7. It is attached. Therefore, the three-dimensional mesh non-woven cloth 3 and the elastic adhesive 5 are provided between the ALC plate 1 and the finishing plate material 7.
Is sandwiched. These three-dimensional mesh non-woven cloth 3 and elastic adhesive 5 have flexibility and elasticity, and absorb the stress between the ALC plate 1 and the finishing plate material 7 generated by thermal expansion and contraction. In particular, the absorption of this stress is largely due to the elasticity of the elastic adhesive 5.

Therefore, even if one of the two ALC plates 1a and 1b to which the finishing plate 7a is adhered is displaced as shown in FIG. 10, for example, the three-dimensional mesh non-woven cloth 3 is softened. The finished plate material 7a is not damaged or peeled off from the ALC plates 1a and 1b due to the elasticity and elasticity of the elastic adhesive 5.

Experiments as shown in FIGS. 11A and 11B were conducted. Here, both ends of the ALC plate 1 are attached to the base 21.
The ALC plate 1 is supported by, and a force is applied to the upper center of the ALC plate 1 to fold the ALC plate 1. On the lower surface of the ALC plate 1, a three-dimensional mesh non-woven cloth 3 is attached by an adhesive, and after drying, an elastic adhesive 5 is applied, and a finishing plate 7 of natural stone is attached. There is.

Even if this ALC plate 1 is broken, FIG.
As is clear from the above, the finished plate material 7 was not damaged.
Of course, when the force is further applied from the upper side, the finishing plate material 7 is also damaged, but even in this case, the fragments of the finishing plate material 7 were not separated.

By the way, as described above, when the unevenness of the wall surface to which the three-dimensional mesh non-woven cloth 3 is attached exceeds 6 mm, the material and application method of the elastic adhesive are changed. For example, a two-liquid mixed type polymer is used as an elastic adhesive, and this elastic adhesive is applied in a dango shape to raise the elastic adhesive to a sufficient height. FIG. 12A shows a state in which the elastic adhesive 22 is formed into a dango shape and arranged vertically and horizontally, and the finishing plate material 23 is adhered thereon. By sufficiently raising this dango-shaped coating, the gap between the wall surface and the finished plate member 23 can be widened. As a result, the wall surface and the finished plate material 23
Even if the irregularity of the wall surface is large, it becomes possible to align the surface positions of the plurality of finished plate materials even if the adjustment range of the gap is expanded.

The pattern of the elastic adhesive may be the pattern shown in FIG.
The pattern shown in 2 (c) may be used. When the elastic adhesive is dispersed and applied in this manner, the elastic adhesive is in sufficient contact with the air, so that the elastic adhesive can be dried and quickly cured by the moisture in the air.

When the elastic adhesive is dispersed and applied,
Even if water droplets enter between the wall surface and each finishing plate material, the water droplets can be guided downward. Considering that this water drop is guided downward, it is necessary to avoid applying the elastic adhesive in a slender shape in the horizontal direction.

[0038]

[Effect] As described above, according to the method for sticking the finished sheet material of the present invention, the stress generated between the wall and the finished sheet material is
The three-dimensional mesh non-woven cloth and the elastic second adhesive are sufficiently relaxed and do not directly act on the finishing board material. For this reason, it is possible to reliably prevent the damage or peeling of the tiles stuck to the wall surface or the finishing plate material such as a flat plate-shaped natural stone material.
