Abstract

PROBLEM TO BE SOLVED: To provide a floor material with a curing sheet not only easily workable but also allowing to reduce manhours at a construction site and prevent the floor material from flawing. SOLUTION: A curing sheet 2 composed of a base material layer 21 and an adhesive layer 22 is stuck to the surface of a floor material 1 without bulging out to one of the breadth end of the floor material 1, and bulging out to the other breadth end by the bulging length within the breadth length. In this case, the floor material with the curing sheet is easily workable because, when it is worked on, only the projected floor material with the curing sheet of the adjoining floor material with the curing sheet is to be turned over and laid over the floor material with the curing sheet not projected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a flooring with a curing sheet.

[0002]

2. Description of the Related Art Since flooring materials such as flooring used in a house or the like are constructed on a construction site and then constructed on walls and ceilings, a curing sheet is usually used so that the surface is not damaged. We carry out curing work such as laying to protect and cure. As such a curing sheet, a sheet described in, for example, Japanese Utility Model Laid-Open No. 3-108154 is known in addition to corrugated paper or a laminate of corrugated paper and a polyethylene film. The curing sheet described in the above-mentioned publication is made of a soft vinyl chloride resin thin plate, and the entire surface of the soft vinyl chloride resin thin plate has parallel wavy uneven shapes, and adjacent wavy uneven shapes can be overlap-engaged.

[0003]

However, the above-mentioned conventional curing sheet is constructed in such a manner that flooring such as flooring is constructed on site and then spread over the entire floor surface, and the ends are fixed with adhesive tape. There is a problem that it takes time and effort. Further, when the flooring material is transported from the factory to the construction site, it is necessary to insert a protective sheet between the flooring materials so that the flooring material is not damaged, which requires extra labor. Also,
Since the surface of the floor material is exposed at the time of floor construction, there is a problem that the floor is damaged at the time of floor construction. In addition, since the curing sheet is laid after the floor material is constructed, there is also a problem that cleaning is necessary before that in order to remove wood chips, dust, sand and the like.

As a method for solving the above problem, as shown in FIG. 4, a curing sheet 2A comprising a base material layer 21 and an adhesive layer 22 is attached to the surface of a floor material 1A as shown in FIG. It is conceivable to use the floor material 10A with a curing sheet that is worn. Curing sheet-attached flooring 10A is obtained by curing sheet 2A having the same size as the exposed surface of flooring 1A.
It is affixed in advance to the floor material 1A. In the flooring 1A, a ridge 14 is formed on one side in the longitudinal direction, and a concave groove 15 that fits with the ridge 14 is formed on the other side. Fig. 5 (b)
As shown in (1), the ridges 14 formed on the side portions are fitted into the concave grooves 15 of the adjacent floor material 1A, and are laid and laid on a floor base (not shown) to construct the floor of the building. Then, after the floor has been constructed, the curing sheet 2A is finally peeled off and removed to expose the surface of the floor material 1A after the construction of the wall and ceiling is completed.

[0005] By using such a flooring 10A with a curing sheet, the problem of using the above-mentioned conventional curing sheet can be almost solved. However, as shown in FIG. In the case of the flooring 1B having cut portions 11 and 11 cut obliquely, a curing sheet 2B having the same size as the exposed portion on the upper surface of the flooring 1B is attached to the flooring 1B. Assuming that the floor material 10B is attached, the cut portion 1
There is no protection function for parts 1 and 11. Therefore, as shown in FIG. 6 (b), when the floor materials 10B with the curing sheet are arranged in parallel and laid, the floor materials 10B
Valley 12 formed by cuts 11, 11 between B
There is a problem that garbage and the like easily accumulate in the car. In addition, when the curing sheet 2B is adhered so as to accurately cover the entire upper surface exposed portion of the flooring 1B, various error factors such as the width of the curing sheet 2B, the width of the flooring 1B, Depending on the positional relationship between the curing sheet 2B and the floor material 1B when worn,
There is also the problem that it is very difficult.

For this reason, as shown in FIG. 7 (a), a floor sheet 10C with a curing sheet and a curing sheet 2C using a curing sheet 2C that covers not only the upper surface exposed portion of the floor material 1B but also the cut portion 11 are provided. It is possible to do. When the floor material with curing sheet 10C is used and constructed as shown in FIG. 7 (b), the above-mentioned drawbacks can be solved. Since it is difficult to confirm whether or not the gaps are in close contact with each other, there is a disadvantage in that the operator must turn over and look at the curing sheet 2C.

Therefore, as shown in FIG. 8 (a), as the curing sheet 2D, a curing sheet having a wide width extending beyond the cut portion 11 to the outside at both ends in the width direction of the flooring 1B is used. It is conceivable to use a flooring 10D with a curing sheet. However, when the construction is performed as shown in FIG. 8B using the floor material 10D with the curing sheet, the curing sheets 2D of the floor material with the curing sheet 10D that are adjacent to each other are turned up at the time of construction so as to overlap each other. It has to be constructed and is troublesome. As shown in FIG. 9, when laying and laying the floor material with curing sheet 10D1, the floor material with curing sheet 10D2, and the floor material with curing sheet 10D3, first, as the work procedure, the floor material with curing sheet 10D1 and the curing are performed. After laying and laying the flooring material with a sheet 10D2 in parallel and then laying and laying the flooring material with a curing sheet 10D3 in parallel, the floor with a curing sheet already stacked on the curing sheet 1D2 of the flooring with a curing sheet 10D2. Curing sheet 1D1 of material 10D1
It is necessary to turn over the curing sheet 1D3 of the flooring material 10D3 with a curing sheet, and to dig it under the curing sheet 1D1, and then to stack the curing sheet 1D1 on the curing sheet 1D3, which is troublesome in construction.

The present invention has been made in view of the above situation, and has as its object to reduce the number of man-hours at a construction site and prevent floor materials from being damaged, and to provide a floor with a curing sheet that is easy to construct. To provide materials.

[0009]

According to the floor material with a curing sheet of the present invention, a curing sheet comprising a base material layer and an adhesive layer protrudes from the surface of the floor material to one end in the width direction of the floor material. Not
It is characterized in that it sticks out to the other end with a protruding length within the width length.

[0010] In the flooring material with a curing sheet of the present invention, the surface of the flooring material refers to the surface of the flooring material that is exposed after floor construction, and the curing sheet is adhered on this surface.

Examples of the substrate layer of the curing sheet include a sheet material formed of a material such as a woven or nonwoven fabric made of synthetic resin, natural fiber or synthetic fiber, and paper. Examples of the synthetic resin include olefin resins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate and polyethylene naphthalate, polyvinyl chloride, polyvinyl halides such as polyvinylidene chloride, polyamide, polyimide, polycarbonate, and polyurethane. Can be mentioned. The sheet material made of the above synthetic resin may be either non-stretched or stretched in a uniaxial or biaxial direction. Further, the synthetic resin may be a foam. Further, the sheet material made of the synthetic resin may be a laminated film in which a plurality of different synthetic resin sheets are laminated. Kraft paper, corrugated paper, or the like can be suitably used as the paper.

In order to produce a cured sheet, for example, a method of applying an adhesive layer on a base material layer using an application device,
A method in which an adhesive layer is extrusion-laminated on a substrate layer, and a method in which the synthetic resin forming the substrate layer and a synthetic resin having tackiness are melt-extruded together when the substrate layer is a synthetic resin. Can be When applying an adhesive, the surface of the substrate is subjected to corona discharge treatment to improve the adhesion between the substrate and the adhesive,
Plasma treatment may be performed, or an intermediate layer for improving adhesion between the base material and the adhesive may be provided. The pressure-sensitive adhesive forming the pressure-sensitive adhesive layer is not particularly limited, but an appropriate material is selected in consideration of durability and removability.

[0013] In the flooring material with a curing sheet of the present invention, the side of the curing sheet that is adhered without protruding to one end in the width direction of the flooring material is located at a position equal to one end in the width direction of the flooring material.
It is preferable that the sheet is adhered to a position within about 5 mm inside. In addition, the side of the curing sheet that sticks out of the flooring material and sticks out of the flooring material with a protruding length within the width of the flooring material, but is usually about 10 to 20 mm as the protruding length. Is preferred. Even if the side to be stuck without protruding above is stuck at a position within about 5 mm inside as described above, at the time of construction, it will be constructed so that the protruding side will be covered, so after construction The flooring is well protected against damage.

In the flooring material with a curing sheet of the present invention, the side of the curing sheet that is adhered without protruding to one end in the width direction of the flooring material and the side that protrudes and adheres to the other end are:
Each is unified on one side in the width direction of the floor material. In this way, when the flooring material is applied, it is possible to carry out the operation so that the side of the curing sheet sticking out without sticking out and the side sticking out and sticking are adjacent to each other. For example, if the floor material has a concave groove on one side in the longitudinal direction and a ridge on the other side, if it is a concave groove, only the concave groove side sticks without protruding. Then, only the side on which the ridges are formed protrudes from the floor material and is adhered.

[0015]

The floor material with a curing sheet according to the present invention has a structure in which the curing sheet is adhered to the surface of the floor material. Floor material can be prevented from being damaged after any construction. In addition, since the curing sheet does not protrude to the surface of the flooring material at one end in the width direction of the flooring material and protrudes to the other end with a protruding length within the width length, and is adhered to the floor, At the time of construction of the material, it is only necessary to turn over the curing sheet that is protruding from the adjacent flooring material with a curing sheet and overlap it with the next protruding one of the flooring material with a curing sheet.
