And sheet tapes 4 are fixedly bonded on one surface side of the joining tape at its center section along its over-all length in the longer direction, so that each warp 2 is prevented from being cut off due to tension force and/or the sheet tape 4.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a joining tape used for reinforcing, joining, etc., and as a corner tape for protecting external and internal corners of internal and external walls of buildings.

0002

[Prior Art] It protects the external and internal corners of concrete, mortar, boards, etc. in buildings, and also protects the joints between boards as well as the joints between concrete, mortar, etc. and boards, and protects them from being broken due to impact. The corner tape that prevents the occurrence of breakage and damage
This is already known from the publication No. 95.

[0003] This known corner tape has a structure in which two thin metal plates are fixed to one side of a porous tape along its length at a predetermined distance in the center of the tape. ing.

[0004] This corner tape is placed along the outer surface of the protruding corner part of the building (it is also used for the inner corner part and the seam of boards), and the center part of the tape is placed along the corner ridgeline of the protruding corner part. That is, the thin plates are bent so that they are aligned, the tape is applied to both sides of the tape with paint putty or adhesive, and the tape is fixed at the protruding corner.Then, the tape is putty treated and finished with a finishing coat to create a buried state.

By embedding the tape, it not only prevents the corner from being chipped or damaged due to external pressure at the protruding corner, but also prevents seams from forming on the finished surface due to the behavior of the boards constituting the protruding corner in different sizes. effective.

[0006]

[Problems to be Solved by the Invention] In the case of corner tapes such as those described above, in the case of an out corner or an inlet corner, a thin plate is placed inside and the tape is bent. tape is pressed against the sharp edge). In particular, the strong pressing force of the metal spatula used in the putty process forces the tape onto sharp corners, which cuts the weft threads of coarsely textured cheesecloth and lifts the thin plate. The above-described phenomenon of lifting of the thin plate also occurs when an impact is applied to the thin plate after the burial process.

For this reason, there is a risk of damage if people or objects come into contact with it, and in order to repair it, the corner tape must be peeled off and a new corner tape applied, which is extremely time-consuming. There was a problem.

[0008] Furthermore, as the weft is cut, the cut end becomes fuzzy, resulting in an inconvenient finished surface. Therefore, an object of the present invention is to provide a joining tape in which the weft yarns are not cut.

[0009]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a joint tape woven with warp and weft yarns, in which the weft yarns have a high tensile rigidity and are difficult to cut. This is what was adopted.

[0010] Furthermore, in a joining tape consisting of a tape woven into a rough texture by warp and weft, and a required number of thin plate tapes fixed along the entire length of the central part on one side of the tape, the weft is The structure uses material that has high tensile rigidity and is difficult to cut. By using weft yarns that have high tensile rigidity and are difficult to cut, cuts caused by tension and cuts caused by contact with the side edges of the thin tape are prevented.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. (First Embodiment) As shown in FIG. 1A, the weft 2 of the joining tape 3 woven with warp 1 and weft 2 has a high tensile rigidity and is difficult to cut.

[0012] The above-constructed joining tape 3 can be wrapped around the crankshaft of a car, the shaft of a golf club, etc. to strengthen it, and can also be used to reinforce or join the joints or welded parts of thin plates or dissimilar plates that cannot be welded. Attach it across the weld mentioned above, and also at the joint of the duct.

[0013] The above-mentioned pasting method is carried out by exposing the adhesive layer (not shown) provided on the entire surface of the bonding tape 3 by peeling off the protective paper, and by using sprayed or applied adhesive. When spraying or applying the adhesive, strong adhesive force can be expected by weaving the fabric into a rough structure so that the adhesive passes through the weave. Further, the weft threads 2 of the joining tape 3 to be pasted are made to intersect at the seam.

(Second Embodiment) As shown in FIG. 1B, the weft yarns 2 of the joining tape 3 woven into a rough texture by warp yarns 1 and weft yarns 2 have high tensile rigidity and are difficult to cut. is used.

Further, a required number of thin plate tapes 4 are fixed along the entire length in the longitudinal direction of the central part on one side of the joining tape 3. The thin plate tape 4 described above is formed using stainless steel, hard synthetic resin, or the like, and is integrally attached to the joining tape 3 using an adhesive 5. The thin plate tape 4 includes two parallel strips with a predetermined interval as shown in FIG. 2, and a three strip tape in addition to the one strip shown in FIG.

As shown in FIG. 4, the bonding tape constructed as described above includes a bonding tape 3 which is bent so that thin plate tapes 4, 4 are circumscribed on the surfaces of the two sides sandwiching the corner at the projecting corner portion 11 of the building. Then, the joining tape 3 is fixed to the above-mentioned protruding corner portion 11 by applying or spraying paint putty or adhesive. Note that the above adhesive may be applied or sprayed before the bonding tape 3 is attached.

[0017] Thereafter, putty treatment is performed so that the entire joining tape 3 is buried, and the surface is finished by finishing painting or the like.

In addition, as shown in FIG. 5, when the corner of the protruding corner 11 is a chamfered corner, an intermediate thin plate tape 4 is circumscribed around the chamfered part, and both sides sandwich the chamfered part. It is used by circumscribing the side thin plate tapes 4, 4.

Furthermore, as shown in FIG. 6 and FIG.
Also used for

The above-mentioned weft yarn 2 having high tensile rigidity and being difficult to cut is made of a rigid polymer such as a wholly aromatic polyester fiber, a wholly aromatic polyamide fiber, or a flexible polymer such as an ultra-high polymerization degree polyethylene fiber or the like. things are used.

In addition, when cutting the required length of the joining tape 3 from the rolled joining tape 3, the warp 1 and the thin tape 4 between the wefts 2 are cut using a cutter or scissors, and the woven wide width to narrow width is cut. When dividing the weft thread into two parts, it is necessary to apply a sealing process using resin or the like to prevent misalignment, and to replace the ceramic blade frequently to prevent deterioration of its sharpness, or to cut the weft thread 2 using a laser or the like. Bye.

[0022]

[Effects] As described above, according to the woven bonding tape of the present invention, the weft has high tensile rigidity and is difficult to cut, so the tensile strength (against force in the breaking direction) is extremely high. It can be used as a reinforcing or joining tape.

[0023] In addition, when the joining tape is bent (using an outside corner or an inside corner), the weft threads may be cut by the sharp side edges of the thin tape, and during putty processing, the strong pressing force and pressure caused by a metal spatula may occur. There is no possibility that the weft threads will be cut due to the sharp side edges of the thin tape due to external impact.

[0024] Therefore, it is possible to avoid inconveniences such as the thin plate tape being lifted up due to cutting of the weft threads, causing damage to people or property, and requiring time and effort to repair.
