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. And a technique for applying the obscuring tape.
The obscuring tape described in the above publication has a configuration as shown in FIG. In FIG. 1, a is a net-shaped obscuring tape main body that does not expand or contract in both the length direction and the width direction. Is adhered in a parallel state with an adhesive c, and a backing material g and a sealing material h are used for a joining portion f of the wall material d and the wall material e, and are bonded to the surface of the upper edge of the c-shaped joint portion i. An agent j is applied by a brush, and the tape body a and the opaque cover sheet b are adhered by the adhesive j. In addition, a second known example shown in FIG. 2 is also known separately from the above known example. 2 is shown for the inner wall, the abutting portion of the V-shaped joint portion i does not use the backup material g or the sealing material h, and the adhesive j is applied to both upper and lower surfaces of the net tape main body a. An opaque release paper n having the same width as the tape main body a is adhered to the upper surface side of the tape main body a, and the tape main body is placed on the joint i of the abutting portion f of the wall materials d and e. After adhering a, the release paper n is peeled off and used. Further, a third known example shown in FIG. 3 is also known. Only the net tape main body a is used without using the cover plate b shown in FIG. 1, and an adhesive j is applied to the lower surface side thereof. The tape main body a is adhered to the surface of the upper edge of the joint portion i. The above-mentioned second and third known examples are mainly used as joint processing tapes for inner walls, and joints i of joints f between wall materials d and e are generally V-shaped or C-shaped. Beveled. After adhering the tape body a to the upper surface of the joint part i, through a mesh of the tape body a, kneading a thick putty m or gypsum is applied several times with a spatula p to fill the joint part i, Furthermore, the surface was coated with a finishing putty to finish.

[0003]

In the first known example, since the adhesive j is applied to both sides of the joint portion i and the tape is attached thereto, it takes time and effort to apply the adhesive j. There is a problem that the adhesive j is applied somewhat wider than the width of the tape body a, so that the adhesive j is applied to an extra part, so that the adhesive j is consumed more than necessary. There is also a problem that the subsequent work is hindered because it is not possible to move to the next work without waiting for time. In the second known example, since the tape body a is a double-sided adhesive tape,
It is not necessary to apply the adhesive j as in the first known example (FIG. 1) to the surface of the upper edge of the joint portion i, and there is no problem associated with the application of the adhesive. Has a problem that the release paper n is required, and the release paper n is opaque, so that the opaque release paper n interferes with and correctly matches the center of the joint portion i. There was a problem of not being able to do it. In the third known example, since the tape body a is a single-sided adhesive tape, it is not necessary to apply the adhesive j as in the first known example to the surface of the upper surface of the joint portion i. Does not use the opaque release paper n as in the second known example, so that the center cannot be matched with the joint i. However, in the second and third known examples, since both are the tape main body a of the mesh, after the tape main body a is adhered, the kneaded thick putty or gypsum m is passed through the mesh of the tape main body a to form a spatula. There is a problem that the joint portion i must be filled using p. The filling of this putty or gypsum m is extremely troublesome in consideration of shrinkage and thinning after drying and curing. Therefore, it is rather preferable that the stainless steel opaque cover sheet b is adhered in parallel with the adhesive c. Known examples are better. Therefore, the present invention is an improvement of the first known example described above so as to further facilitate use.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a tape main body formed of a net-like material which does not expand or contract in either the length direction or the width direction, and the upper surface of the tape main body is kept as it is. At the center of the lower surface side, a transparent or translucent opaque film or opaque plate narrower than the tape body is attached in parallel with an adhesive, leaving the left and right sides of the tape body,

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described with reference to FIG. 4 and the following. Reference numeral 1 denotes a tape main body, which is formed of a net-like material which does not expand or contract in the length direction or the width direction. I have. As an example, it is formed by twisting aramid fiber or glass fiber which is not likely to be rusted or deteriorated. 2 is a weft, 3 is a warp.

An adhesive 4 is provided on the lower surface of the tape body 1.
A transparent or translucent obscuring film or opaque plate is adhered to the opaque film. A transparent or translucent obscuring film is formed of a synthetic resin film, and an opaque plate is formed of a thin metal plate such as stainless steel. The width of the covering film or the covering plate 4 is narrower than the width of the tape body 1, and is adhered to the center of the tape body 1 except for stopping portions 6 and 7 on the left and right sides of the tape body 1. The adhesive 5 may be applied to the upper surface each time the covering film or the covering plate 4 is attached, but an adhesive layer may be formed in advance like a known adhesive tape.

The upper surface of the tape body 1 is left as it is, and nothing is formed. This facilitates the work when the upper surface is rubbed for spreading wrinkles. The adhesive layers 8 are applied or impregnated entirely on the left and right stop portions 6 and 7 on the lower surface side of the tape main body 1 and on the lower surface of the covering film or the covering plate 4. In addition, the cover film or cover plate 4
Is not bonded to the joints, so that the bonding layers 8 may be formed only on both sides as shown in FIG. FIG. 8 will be described later.

The tape of the present invention has the above-mentioned structure, and is wound around a roll 9 like an ordinary cellophane tape (FIG. 5), stretched to a desired length from one end, and cut for use. . That is, there is no opaque release paper n as in the second known example. In addition, 10 is a plaster board, a lightweight cellular concrete board, a cement extruded board, an asbestos slate board, a calcium silicate board, a precast concrete board,
A wall material composed of other components, 11 is a joint portion of the wall material 10, 12 is a joint portion spreading in a V-shape or V shape, and 13 is a sealing material to be filled in the joint portion 7 applied to prevent water leakage in the case of an outer wall. (See FIG. 1), 14 is a finish putty, and 15 is a spatula. FIG. 8 is an inverted view, in which a transparent or translucent occluding film or obscuring plate 4 is adhered to the lower surface side of the tape main body 1 with an adhesive 5, and adhered only to both sides of the occluding film or the obscuring plate 4. A layer 8 is formed, and a release paper 1 is formed on the lower surface of the adhesive layer 8.
6 is affixed.

[0009]

Next, the operation will be described. On the outer or inner wall of the building,
When the wall materials 10 and 10 are hit against each other, the wall materials 10
An outwardly-opening V-shaped or C-shaped joint 12 as shown in FIG. The joint portion 12 is filled with the sealing material 13 on the outer wall surface to prevent water leakage, but is not usually filled with the sealing material 13 on the inner wall surface.
When the tape body 1 wound around the roll of the present invention is pulled out from one end and brought into contact with the upper surface of the joint portion 12, the tape body 1 can be easily pulled out and adhered onto the joint portion 12.

In this case, since the adhesive layer 8 is formed on the left and right stoppers 6 and 7 of the tape body 1 and the lower surface of the covering film or covering plate 4 in the center, the joint 12 is covered with the covering. Since the film or the cover plate 4 is adhered to the wall materials 10 and 10 so that the stop portions 6 and 7 are double-enclosed, it is extremely easily and surely adhered. In the case of the embodiment shown in FIG. 8, the release paper 16 is peeled off before bonding.

After the tape main body 1 is attached, a finishing putty 14 for covering the outer surface of the net-shaped tape main body 1 is applied with a spatula 15, and then the upper surface thereof is covered with a waterproof polyurethane-based polyurethane. , Cement-based, acrylic-based or other coatings, and the inner walls can be finished with synthetic resin emulsion coating, cloth paste, etc.
The joints 12 of the joints 11 can easily be made inconspicuous, and a beautiful wall surface in which traces of the joints 12 have disappeared can be formed. At this time, since the covering film or the covering plate 4 of the present invention is adhered to the wall materials 10 and 10 by the adhesive layer 8, no deviation occurs even if the finishing putty to be covered is applied with a spatula.

[0012]

According to the first known example, since the adhesive j is applied to both sides of the joint portion i and the tape is attached, the adhesive j
And it is troublesome because it requires time and labor to apply the adhesive j. Since the adhesive j is applied somewhat wider than the width of the tape body a, the adhesive j is applied to an extra portion, so that the adhesive j
There is also a problem that the following work is consumed unnecessarily, and that the next work cannot be started without waiting for the curing time of the adhesive j, which hinders the subsequent work. In the second known example, since the tape main body a is a double-sided adhesive tape, it is not necessary to apply the adhesive j as in the first known example (FIG. 1) to the surface of the upper edge of the joint i. Although there is no problem related to the above, it is a double-sided pressure-sensitive adhesive tape and the release paper n is adhered to the upper surface, so that the release paper n is required, and since the release paper n is opaque, the opaque release paper n However, there was a problem that the center could not be correctly aligned. In the third known example, since the tape body a is a single-sided adhesive tape, it is not necessary to apply the adhesive j as in the first known example to the surface of the upper edge of the joint portion i.
Since the opaque release paper n as in the second known example is not used on the upper surface of the second embodiment, the point that the center cannot be matched with the joint portion i is also improved. However, both the second known example and the third known example are only the tape main body a of the mesh, so after bonding the tape main body a, through the mesh of the tape main body a,
There is a problem that a kneaded thick putty or gypsum m must be filled in the joint portion i using a spatula p. However, according to the present invention, the tape body 1 is formed of a net-like material that does not expand or contract in the length direction or the width direction, the upper surface of the tape body 1 is left as it is, and the center of the lower surface side of the tape body 1 is A transparent or translucent opaque film or opaque plate 4 narrower than the tape body 1 except for the left and right sides of the tape body 1 is stuck in parallel with an adhesive 5, and the tape body 1 and the opaque film or Since the lower surface side of the cover plate 4 is a cover tape for joint treatment prepared by applying or impregnating the adhesive 8, there is no need to apply the adhesive j when compared with the first known example. This eliminates the need to apply the adhesive j, eliminates the waste of applying the adhesive j wider than the width of the tape body a, and eliminates the waste of waiting for the curing time of the adhesive j. In addition, when compared with the second known example and the third known example, since the putty m for filling the joint portion i is not required,
It has the effect of being easy to handle. Further, since the covering film or the covering plate 4 is a covering tape for joint treatment in which the adhesive layer 5 is provided on the upper surface side in advance, it is easy to manufacture. The left and right widths of the covering film or the covering plate 4 are the wall materials 1.
Since the width of the joint portion 12 formed by abutting 0 is larger than that of the joint portion 12, the joint portion 12 can be reliably covered. An adhesive 8 is applied only to both end portions on the lower surface side of the covering film or the covering plate 4.
Is applied or impregnated, and the release paper 16 is adhered to the lower surface of the adhesive 8, so that handling becomes easier.
