Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seam construction method for a floor material made of synthetic resin, which is adhered to a base material via an adhesive.

[0002]

2. Description of the Related Art Conventionally, as a seam construction method of a synthetic resin floor material that is adhered to a base material with an adhesive, a floor material that has been adhered to the base material with an adhesive agent applied A seam solution containing an organic solvent such as tetrahydrofuran or methyl ethyl ketone as a main component and a synthetic resin component as necessary (in the present specification, may be simply referred to as "seam solution") is injected into the seam of the material. , A seam construction method for floor materials that welds adjacent floor materials to each other (hereinafter referred to as "seam construction method") is used. This seam construction method has fewer construction steps than the seam construction method by welding, which is also used for the seam construction of flooring materials that are adhered to the base material via an adhesive,
Since it has the advantage that construction can be performed easily, it is widely used in work sites where skilled workers cannot afford it.

[0003]

By the way, in this seam construction method, since the seam liquid is directly injected into the seam of the adhered flooring material, if the amount of the seam liquid to be injected is too large, the seam liquid is injected. The liquid overflows onto the surface of the flooring material and attacks the surface of the flooring material, and the synthetic resin component of the seam fluid remains on the surface of the flooring material, which deteriorates the appearance of the flooring material. If there is too little, there is a problem that adjacent flooring materials are not sufficiently welded to each other and the required adhesive strength cannot be obtained, and as a result, the work of pouring the seam liquid must be carefully performed. It had a problem that it took time.

In addition, in order to protect the surface of the floor material from the seam liquid, it is theoretically possible to adopt a method of applying masking tape along both edges of the adjacent floor material. Since the size of the gap between the seams of the adhered floor material that injects the liquid is extremely small, it is actually difficult to accurately apply the masking tape along both edges of the adjacent floor material, Further, even with this method, the problem that the construction takes time could not be solved.

The present invention solves the problems of the above-mentioned conventional seam construction methods such as the seam construction method, and requires no skill in construction, and improves the work accuracy and work efficiency. The purpose is to provide a seam construction method.

[0006]

In order to achieve the above-mentioned object, a method for constructing a seam of a flooring material according to the present invention is such that a flooring material is adhered to an underlayer via an adhesive agent and is formed between the adhered flooring materials. Adhesive tape is attached to the surface of the floor material so as to cover the upper portion of the seam having a gap of a predetermined width, a cut is formed along the seam on the adhesive tape, and a seam liquid injection nozzle is formed at the cut of the adhesive tape. Is inserted, the seam liquid is injected into the joint while moving the injection nozzle along the cut line of the adhesive tape, and the adhesive tape is peeled off. In this case, the "gap of a predetermined width formed between the adhered floor materials" usually means
0.05-0.5 mm, preferably 0.1-0.3 m
It means a gap of m. The gap can be provided in advance when the floor material is attached to the base, or can be formed by attaching the floor material to the base and then cutting off a part of the floor material.

As a result, even if the amount of the seam liquid to be injected into the seam of the adhered floor material is too large, the seam liquid only overflows from the break of the adhesive tape to the surface of the adhesive tape, and the surface of the floor material is not covered. Does not affect the appearance of the flooring material. Further, since the amount of the seam liquid to be injected is not made too small because the seam liquid overflows on the surface of the floor material, the working accuracy such as the adhesive strength of the floor material can be improved. In addition, since the adhesive tape may be simply attached to the surface of the floor material so as to cover the upper part of the seam of the adhered floor material, a cut line may be formed along the seam, so the work efficiency of attaching the adhesive tape, etc. In contrast, the seam injection work can be performed smoothly, so that the work efficiency can be improved.

In this case, it is desirable to use a transparent adhesive tape as the adhesive tape.

[0009] With this, it is possible to accurately form a cut on the adhesive tape along the seam of the floor material, and to inject the seam solution into the seam of the adhered floor material while checking the amount of the seam solution. It is possible to prevent excessive injection of the seam liquid.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a floor material seam construction method according to the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an example of the construction steps of the seam construction method for flooring of the present invention.

The floor material 2 is attached to the base 1 via the adhesive 3 (FIG. 2 (a)). In this case, the material of the adhesive 3 needs to be determined according to the material of the base 1 and the floor material 2 and the environment of the construction site. For example, the material of the base 1 is concrete and the material of the floor material 2 is chloride. In the case of vinyl resin, it is desirable to use urethane resin-based or epoxy resin-based adhesive.

A gap C1 having a predetermined width between the adhered floor materials 2 and 2
Are formed (FIG. 2B). This gap C1 allows the injection nozzle 6a of the seam liquid to be inserted in the step described later, and when the seam liquid is injected into the joint 4 of the floor materials 2 and 2, the adjacent floor materials 2 and 2 are firmly welded to each other. To the extent possible, specifically, 0.05 to 0.5 mm, preferably,
It is formed to have a thickness of 0.1 to 0.3 mm. In addition, this gap C1
Can be formed by adhering the floor material 2 on the base 1 and then cutting off a part of the floor material 2, or can be provided in advance when the floor material is adhered on the base.

After cleaning the surfaces of the floor materials 2 and 2 and the inside of the seam 4, the surfaces of the floor materials 2 and 2 are covered so as to cover the upper part of the seam 4 having a gap C1 having a predetermined width formed between the floor materials 2 and 2. Adhesive tape 5 is attached to (FIG. 2 (c)). In this case, the adhesive tape 5 is, for example, a polyolefin resin-based adhesive tape having a property not to be attacked by the seam liquid, and is an adhesive tape along the seam 4 of the floor materials 2 and 2 in the step described later. 5 so that the cut 5a can be accurately formed, and the seam liquid can be injected into the seam 4 of the floor materials 2 and 2 while confirming the amount of the seam liquid. It is desirable to use a dressing tape. Further, the adhesive tape 5 can be attached to both surfaces of the floor materials 2, 2 and the adhesive tape 5 so that the seam liquid does not enter, and after the construction, the floor material 2, 2
It is necessary to use a material that can be easily peeled off from the surface of 2.

A single slit 5a is formed on the adhesive tape 5 along the seam 4 of the floor materials 2, 2 with a knife or the like (FIG. 2).

While inserting the injection nozzle 6a of the seam liquid container 6 into the cut 5a of the adhesive tape 5 and moving the injection nozzle 6a along the cut 5a of the adhesive tape 5, that is, the joint 4 of the floor materials 2 and 2, The seam solution is injected into the seam 4 (FIGS. 1 and 2 (e)). In this case, the components of the seam liquid need to be determined according to the material of the flooring 2,
For example, when the material of the floor material 2 is vinyl chloride resin, an organic solvent such as tetrahydrofuran or methyl ethyl ketone can be used. If necessary, a seam liquid containing a synthetic resin component can be used as the seam liquid. Especially, when the width of the gap C1 formed between the floor materials 2 and 2 is large, By using the seam liquid containing, it is possible to firmly weld the adjacent floor materials 2 and 2. If the amount of the seam liquid injected into the seam 4 of the floor materials 2, 2 is insufficient, the floor materials 2, 2 may not be sufficiently welded to each other and the required adhesive strength may not be obtained. Is the cut 5a of the adhesive tape 5.
It is desirable to inject the adhesive tape 5 so that it leaks to the surface of the adhesive tape 5 to a slight extent, for example, a width of 3 to 5 mm.

After injecting the seam solution, curing is performed for about several minutes, the adhesive tape 5 is peeled off from the surfaces of the floor materials 2 and 2, and the surface finish of the floor materials 2 and 2 and the seam 4 is finished as necessary. Then
The adhesive 3 is cured.
