Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a sheet-like wall material having a surface having a lot of irregularities on the outer wall or the inner wall surface of a building.

[0002]

2. Description of the Related Art Various kinds of decorative coatings are applied to outer and inner walls of buildings. In recent years, various artificial materials have been used for this decorative coating, and in particular, sheet-shaped wall materials are easy to handle. It is used a lot.

As one of various sheet-shaped decorative wall materials, one having a thickness of several millimeters and a surface having natural stone-like unevenness such as granite is known. Conventionally, as a construction method for decorative finishing of a wall surface using such a sheet-shaped decorative wall material,
It is common practice to first prepare the groundwork, then stamp with ink, apply an adhesive, attach a sheet-like wall material, and finally finish the joint portion with a sealing material.

However, when a joint material is filled with a sealing material after a thin sheet-like wall material having an uneven surface is pasted, the sealing material easily leaks from the concave portion on the side surface of the wall material to the joint surface. Even if the surrounding area is cured with a curing tape, it takes a lot of time and labor to finish the work beautifully.

[0005]

Therefore, a string-like joint rubber is used for the joint, and first, the string-like joint rubber is attached on the ink striking line, and then the sheet-like wall material is placed in the section surrounded by the joint. The method of installation was examined. However, with this method, it is almost impossible to finish without forming a gap in the joint, and not only the sealing function of the joint is insufficient, but also the finished appearance is poor.

An object of the present invention is to provide a method of constructing a wall material which has a sufficient sealing function, has a good finished appearance and does not require skill.

[0007]

That is, the present invention relates to a step of applying an adhesive on a wall surface whose surface has been adjusted, and a sheet-like surface having an uneven surface on which a protective film is attached on the back surface. A step of spreading the wall material and a string-shaped joint rubber, a step of removing the sheet-shaped wall material from the wall surface, and a step of applying an adhesive on the wall surface from which the sheet-shaped wall material is removed,
And a step of reattaching the sheet-shaped wall material from which the protective film on the back surface is peeled off to the original partition surrounded by the joints on the wall surface.

[0008]

In the construction method of the present invention, first, dust, oil and fat, etc. on the wall surface are removed and cleaned, and if there are inconvenient irregularities, the base is adjusted using resin mortar or the like.
The inner wall of the building is suitable as the wall surface, but it can also be applied to the outer wall construction. Further, the wall surface is not limited to a flat surface and may be a curved surface. Next, an adhesive is applied on this wall surface. The adhesive is usually applied twice, but in the present method, the application of the adhesive in the first stage may be applied once.

The sheet-like wall material used in this method is a wall material having a surface with irregularities and a back surface provided with a protective film. It is not necessary to dare to apply this method to a wall material that has no unevenness on the surface and has a certain thickness and the sealing material does not leak onto the surface of the wall material during construction. It is preferable that the sheet-shaped wall material has a protective film (including release paper) affixed to its back surface in advance. However, if the protective film is not affixed, a protective film is applied.
The protective film may be used without particular limitation as long as it does not adhere completely depending on the adhesive used, but a film made of polyolefin, for example, is preferable. The sheet-shaped wall material usually has a rectangular plate shape with one side of 20 to 100 cm, but the shape and size thereof are not particularly limited. The cord-like joint rubber referred to in the present invention is a cord-like member having a width of 3 to 10 mm, a thickness of about 2 to 8 mm, and smooth side and back surfaces, which are appropriately cut and used as joints. Is. Preferable ones include those having a cured rubber on the front surface and an adhesive butyl rubber attached to the back surface together with release paper.

Sheet-shaped wall material and string-shaped joint rubber are alternately placed on the wall surface before the adhesive is completely cured after the preparation is completed, and the wall material is laid without gaps. How to spread
Various modes such as a lattice pattern and a zigzag lattice pattern can be adopted. At this time, the sheet-like wall material is first applied, the joint rubber is adhered to the side portions thereof without any gaps, and then the sheet-like wall material is adhered to the joint rubber in a continuous manner. Temporarily attach wall material and joint rubber to the. The adhesive force between the wall material and the wall surface at this time is sufficient as long as the wall material does not drop from the wall under its own weight. Further, since the adhesive force is weakened by the protective film instead of the main attachment to the wall surface, it is possible to easily adjust the positions of the wall material and the joint rubber, and it is possible to perform the spread without forming a gap. After paving is complete, remove all sheet-like wall material from the wall. At this time, it is necessary to take care not to shift the attachment position of the joint rubber.

Next, the adhesive is applied again to the inside of the section surrounded by the joints on the wall surface from which the sheet-shaped wall material has been removed. When the adhesive has dried to a state suitable for bonding,
The protective film on the back surface of the sheet-shaped wall material is peeled off and removed, and the sheet-shaped wall material is fitted and reattached in the section surrounded by the original joint. At this time, with respect to the joint rubber, the adhesive has already been completely cured, and the position does not move by the fitting operation of the sheet-shaped wall material. Further, in this operation, it is preferable from the viewpoint of sealing property and appearance that the sheet-shaped wall material is put back to the original position where it was temporarily attached by marking the back surface of the sheet-like wall material.

According to the method of the present invention, it is not always necessary to attach the wall material to the entire wall at once, as in the embodiment described later, the bottom row is first attached, and then the upper row is moved to the upper portion in order. It is also possible to carry out by partially dividing as described above.

In this way, after the completion of the attachment of the sheet-shaped wall material, the working condition is inspected, the defective portion is corrected, and the hardening of the adhesive is completed, the construction of the wall material is completed.

[0014]

[Examples] After removing dust and the like from the inner slate plate on the inner wall by cleaning the unevenness of the surface with putty material and adjusting the ground, the surface finish is granite-like wall material (thickness 3-
The center line was black-printed to determine the position to attach the 4 mm sheet, trade name Die Art, manufactured by Mitsubishi Rayon Co., Ltd. according to the layout diagram that was determined in advance. Next, a dedicated bond (adhesive) was applied to the entire substrate at a rate of 0.3 kg / m ² using a wool roller and a brush, and was cured for about 20 minutes until the dedicated bond dried and became semitransparent.

Diart (size) 600 mm × 450
mm) is temporarily attached to the predetermined position of the first stage without removing the protective film (polyethylene) on the back surface, and string-like joint rubbers (thickness 2.5 mm, width 5 mm, which are joints on both sides thereof)
Cut the chloroprene rubber on the surface layer and the butyl tape on the back side according to the size of the die art in advance, and attach it without any gaps. Temporarily attach the die art to the side of the die art and then attach the joint rubber as well. All the joint rubber of the eyes was attached and fixed. The corners were adjusted by cutting the die art from the back side with an NT cutter according to the remaining size. Then remove all the temporarily attached die-arts and apply a special bond again to the substrate at a rate of 0.1kg / m ² so as not to contaminate the joint rubber, and immediately peel off the protective film on the back side of the die-arts. After sticking on, it was rolled with a rubber roller. After the construction of the first step was completed, horizontal joints were continuously attached and fixed, and the construction of the second step was started in the same manner as above. The diart sheet was attached so that it would be in a zigzag pattern and the position would be half offset from the first stage.

[0016] By repeating the above-mentioned operation to the fifth step, the sheet and joint rubber could be finished neatly without any gap.

[0017]

According to the construction method of the present invention, since the joint portion is formed by sticking the joint rubber, the joint portion can be constructed without requiring special skill. In addition, since there is no gap between the joint rubber and the sheet-shaped wall material, the sealing function is sufficient and the finished appearance is good.
