Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a covering tape for joint treatment.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Application Laid-Open No. Hei 8-170420 discloses that a joint is added to a joint such as a PC board or a lightweight cellular concrete board which is a wall material of a building, so that the appearance is further added. It describes a technique for applying an obscuring tape capable of producing a high-quality beautiful finish.

[0003]

The above-mentioned known example has a problem that it is difficult to use because the device and the position of the release paper are insufficient. In the present application, the position and width of the release paper are devised to facilitate use.

[0004]

According to the present invention, a tape-shaped tape body 1 is formed of a net-like material, and an opaque film 4 having a width smaller than that of the tape body 1 is provided at the center of the lower surface side of the tape body 1.
Are provided in a parallel state, and an adhesive is applied or impregnated on the lower surfaces of the tape body 1 and the covering film 4, and a release paper 3 wider than the tape body 1 is provided on the upper surface of the tape body 1.
In parallel to form an obscuring tape for joint treatment. In the present invention, the adhesive on the lower surface of the tape body 1 is applied or impregnated so as to slightly exude to the upper surface of the tape body 1 to form an occluding tape for joint treatment.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a tape main body, which is formed of a net or a non-woven fabric, which is made of a material which does not expand or contract in a length direction or a width direction. ing. As an example, it is formed by twisting aramid fibers having no fear of rusting or deterioration. The tape body 1
The adhesive 2 is applied or impregnated from the lower surface to the entire surface, and the adhesive 2 is not applied to the upper surface, but the adhesive 2 on the lower surface slightly exudes and the release paper 3 on the upper surface of the tape body 1 is adhered. So that it can be fixed. The release paper 3 is formed wider than the tape body 1. The pressure-sensitive adhesive 2 is made of acrylic, rubber, polyethylene, urethane, or the like, and adheres to a wall material at room temperature.

Reference numeral 4 denotes an occluding film which is attached to the center of the lower surface side of the tape main body 1 in the width direction so as to be narrower than and parallel to the tape main body 1 and is attached thereto. The occluding film 4 is transparent, translucent or woven (net) -shaped. It is formed of a synthetic resin or other material. The covering film 4 is adhered by an adhesive 2 provided on the lower surface side of the tape main body 1. However, depending on the adhesive 2 used, the covering film 4 may be difficult to be adhered. The adhesive layer 5 may be formed on the upper surface side.

[0007] Further, an adhesive layer may or may not be formed on the lower surface side of the covering film 4. When an adhesive layer is formed on the lower surface side of the covering film 4, the covering film 4 may be coated or impregnated on the entire surface, or may be formed so that the adhesive 2 and / or the adhesive layer 5 oozes on the lower surface side.

FIG. 6 shows another embodiment, in which an adhesive layer 6 is provided on the lower surface on the left and right sides of the covering film 4 and the tape body 1, and the adhesive material is slightly attached to the upper surface of the tape body 1. Coated or impregnated so that it oozes out.

Thus, the tape of the present invention has the above-described structure, and the cover film 4 and the lower surface on the left and right sides of the tape main body 1 are adhered to the release paper 3 on the upper surface side, so that the tape is similar to an ordinary cellophane tape. It is wound on a roll 7 and adhered to a wall surface while being stretched from one end. After being adhered, the release paper 3 is peeled off and used. In the figure, 8 is a plaster board, a lightweight cellular concrete board, a cement extruded board, an asbestos slate board,
A wall material composed of a calcium silicate plate, a precast concrete plate, etc., 9 is a joint portion of the wall material 8, 10
Is a joint portion that spreads in a C-shape or V-shape, and 11 is a filler such as putty filled in the joint portion 10.

[0010]

Next, the operation will be described. On the outer or inner wall of the building,
When the wall materials 8 and 8 are abutted against each other, an outwardly open V-shaped or C-shaped joint portion 10 is formed at the joining portion 9 of the wall materials 8 and 8. When the tape body 1 in the form of a roll 7 is pulled out and brought into contact with the upper surface of the joint portion 10, it is easily pulled out and brought into contact.

In this case, since the adhesive 2 is applied (impregnated) to the lower surface side of the tape body 1, when the tape body 1 is pulled out from the roll 7 together with the release paper 3, it is adhered to the wall materials 8, 8 as it is. After that, the release paper 3 is peeled off, and a finishing putty 12 for slightly covering the outer surface of the net-shaped tape body 1 is applied with a spatula 13, and then, on the upper surface thereof,
For the outer wall, waterproof polyurethane-based, cement-based, acrylic or other paint, and for the inner wall, synthetic resin emulsion paint, cloth paste, etc.
The joint portion 10 of the joining portion 9 of the wall materials 8 and 8 can be easily made inconspicuous, and a beautiful wall surface with no trace of the joint portion 10 can be formed.

Therefore, since the tape body 1 is adhered while being pulled out from the roll 7 together with the release paper 3, workability is greatly improved. Further, since the release paper 3 is adhered to the adhesive 2 slightly oozing from the lower surface side to the upper surface side of the tape main body 1, it can be easily peeled. Further, since the release paper 3 is formed wider than the tape main body 1, it is possible to prevent the tape main body 1 from being peeled off during the peeling operation.

[0013]

According to the present invention, a belt-shaped tape body 1 is formed from a net-like material, and an occluding film 4 having a width smaller than that of the tape body 1 is provided in parallel at the center of the lower surface side of the tape body 1. An adhesive is applied or impregnated on the lower surface side of the tape body 1 and the covering film 4, and a release paper 3 wider than the tape body 1 is stuck on the upper surface side of the tape body 1 in a parallel state. Because the tape was obscured, the tape itself 1
The amount of adhesive oozing on the upper surface of the
Also, since the left and right ends of the release paper 3 are formed slightly longer than the tape body 1, the work is easy, and the release paper 3 is attached to the upper surface of the tape body 1 instead of the lower surface, so that it is extremely easy to use. Having. According to the present invention, the adhesive on the lower surface side of the tape body 1 is an occluding tape for joint treatment which is applied or impregnated so as to slightly exude to the upper surface side of the tape body 1. The material can be slightly exuded, and the problem of stickiness due to too much adhesive can be solved.
