Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining tape used for protecting the projected corners of inner and outer walls in a building.

[0002]

2. Description of the Related Art In order to protect the outer corners of the inner and outer walls of a building, the applicant of the present invention, as described in Japanese Utility Model Publication No. 55-6985, provides a space at the center of one side of a porous tape. We proposed a corner tape with two thin strips fixed along the length of the tape.

In this corner tape, the ridgeline of the projected corner is positioned between the thin plates, the tape is bent along the wall surface, fixed with a putty on the wall surface, and then buried in a mortar or the like. The projected corner is protected by the thin plate, and damage to the projected corner when an object is hit is prevented. In addition, since the tape is porous, the putty penetrates the tape, and mortar and the like are reliably bonded.

[0004]

However, in the above-mentioned corner tape, since the tape is pulled in the width direction at the ridge line portion of the projected corner, the spatula is strongly pressed and the ridge line of the projected corner is pressed at the time of mortar finishing. If you rub along it, the tape may break and the thin plate may flip up.

Therefore, an object of the present invention is to provide a joining tape which is excellent in tensile strength in the width direction of the tape and which is hard to break.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a tape woven by a warp yarn and a weft yarn having a coarse texture and extends in the longitudinal direction of the tape at a central portion on one side of the tape. In the joining tape to which a plurality of thin plates are fixed,
The weft is made of a material that has high tensile strength and is difficult to cut.

[0007]

When the joining tape according to the present invention is used to protect the projecting corner, the ridgeline of the projecting corner is positioned between the thin plates, the tape is bent, and the tape is fixed to the projecting corner with putty, and then mortar or the like is used. Finish buried. Since the tape has a coarse mesh,
The putty penetrates the tape, and mortar and the like are securely bonded.

Further, since the weft of the tape is hard to break, even if the spatula is strongly rubbed along the ridgeline of the projected corner for applying putty or mortar, the risk of cutting the tape is low.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, two thin strips 4 extending in the longitudinal direction of the tape 3 are fixed at a central portion on one side of a tape 3 woven by a warp 1 and a weft 2 in a coarse structure. Has been done. The weft 2 has a large tensile strength,
A material that is difficult to cut is used. Examples of this material include rigid polymeric materials such as wholly aromatic polyester fibers, wholly aromatic polyamide fibers, and flexible polymer ultra-high degree of polymerization polyethylene fibers. The thin plate 4 is preferably made of stainless steel.

When the above-mentioned joining tape is used to protect the projecting corner portion, as shown in FIG.
Bend the tape 3 with the ridgeline of the
After fixing to No. 1, it is buried in mortar. Since the tape 3 has a coarse mesh, the putty penetrates the tape 3 and mortar or the like is reliably bonded. Further, since the weft yarn 2 of the tape 3 is difficult to break, even if a spatula is strongly rubbed along the ridgeline of the projected corner for applying putty or mortar, the risk of the tape 3 being cut is low.

The above-mentioned joining tape can also be used for protecting the inner corner 12, as shown in FIG.

Further, as shown in FIG. 5, when the projecting corner 11 is chamfered, a joining tape provided with three thin plates 4 is used.

[0013]

As described above, according to the present invention, since it has the above-mentioned structure, it has excellent tensile strength in the width direction of the tape, and when protecting the protruding corner, the ridgeline of the protruding corner is positioned between the thin plates. Even if the tape is bent and the spatula is rubbed strongly along the ridgeline of the projected corner for applying putty or mortar, the risk of cutting the tape is low.

Further, since the tape has a coarse mesh, the adhesive putty penetrates the tape, and the mortar and the like are reliably bonded.
