Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method of sequentially laying a plurality of floor material unit pieces in a rectangular, rectangular or other shape on a subfloor material with their edges brought into close contact with each other. Regarding construction methods for flooring materials.

[Prior art]

This type of flooring material, known by names such as tile carpet and P tile, can be freely combined.
It has been widely used as a flooring material in recent years because it has many advantages such as allowing users to freely create various designs and making it easy to replace partial members.

Conventionally, to install this type of tile-like flooring, the construction method is to use adhesives with good peel-up properties, such as acrylic or SBR adhesives, to sequentially adhere flooring unit pieces onto the subflooring material. A method using highly adhesive double-sided adhesive tape such as carpet tape has been adopted.

However, since the above-mentioned adhesive with good peel-up properties is an emulsion type, initial tack strength cannot be obtained until at least 10 minutes have passed at a temperature of 25°C. Even if you attempt to arrange the next flooring unit piece next to it using it as a guide, the flooring unit piece that serves as the guide will not be stable and accurate construction will not be possible. It also has the disadvantage that it takes time to obtain sufficient tack force, and the construction is too labor intensive. Moreover, when a unit piece of flooring material is removed, adhesive remains on the subflooring material and on the back side of the removed unitary unit piece of flooring material, so the adhesive on the subflooring material must be removed using a special cleaning agent. Must be. When storing the removed flooring unit piece, a release film must be interposed to prevent the adhesive from adhering to it, which makes the process troublesome.

On the other hand, in the case of a construction method using double-sided adhesive tape, although the initial tack force is strong, it lacks peel-up properties and has the disadvantage that flooring unit pieces are difficult to peel off from the subflooring material. Moreover, when used for a long period of time, there is also the disadvantage that adhesive substances remain attached to the flooring material and flooring unit pieces.

As an alternative to these construction methods, flexible
A method is also known in which a unit piece of flooring material is laid with a non-adhesive non-slip material made of PVC or the like interposed therebetween. In this case, when a load is applied from above the flooring unit piece, it has an anti-slip effect, but at the time of construction, only the weight of the flooring unit unit is applied, so it is slippery and cannot function as a guide during installation.

[Problem that the invention seeks to solve]

This invention solves the above-mentioned problems in the conventional example, and provides a flooring material that can be quickly laid down and replaced easily without using any adhesive medium such as adhesive or double-sided adhesive tape. The purpose is to provide a construction method.

[Means for solving problems]

This invention relates to a flooring construction method in which a plurality of flooring unit pieces in a rectangular, rectangular or other shape are sequentially laid on a subflooring material with their edges in close contact with each other. A unit piece of flooring material is placed on top of the material, temporarily fixed with a nail that can be easily pulled out from its surface, and the nail is removed after the installation is completed over the entire floor area surrounded by boundary materials such as walls and parting materials. It is characterized by this. Temporary fixation with nails is performed only on the flooring unit pieces at predetermined positions, and other flooring unit pieces may be laid one after another using this temporarily fixed flooring unit piece as a guide. It may be temporarily fixed over a period of time.

〔Example〕

An embodiment of the present invention will be explained based on FIGS. 1 to 5.

The flooring construction method of this example is carried out by the following steps.

(1) Find the center on the subfloor material 2 of the floor area surrounded by the wall material 1 in a rectangular shape, and perform the layout in a cross shape from this center position [Figure 1 a].

(2) The flooring unit pieces 4 are temporarily fixed with nails 5 along the cross-shaped allocation line 3 as shown in FIG. They are arranged closely [Fig. 1b].

(3) For each surface area partitioned into four by the temporarily fixed flooring unit pieces 4, using the temporarily fixed flooring unit pieces 4 as a guide, move in the radial direction shown by the arrow marks in Figure 1 c. Other flooring unit pieces 4 are laid one after another. In this case, the flooring unit pieces 4 are placed while being pressed against the reference line, that is, in the direction in which the previously temporarily fixed flooring unit pieces 4 are arranged. Temporary fixing may be omitted when laying flooring unit pieces 4 other than the previously temporarily fixed flooring unit pieces 4, but if temporary fixing is performed for every few pieces, the laying can be done more accurately and quickly.

(4) Wall material 1 that cannot fit one of the floor material unit pieces 4
After laying a small piece 4' obtained by cutting the floor material unit piece 4 in the peripheral area near the area, the nail 5 at the tip is removed [FIG. 1b].

The flooring unit piece 4 has a rectangular, rectangular, or other shape. The material structure is such that a backing material 4b is laminated to a surface material 4a and integrated. Materials for the surface material 4a include carpet materials such as loop pile and cut pile, rattan, hemp, rush, and wood materials arranged in strips to give flexibility, and elongated wood materials. It is preferable that the nail 5 is formed in such a manner that the nail 5 can be driven from the surface.
The material and shape are not limited as long as they can be placed while being pressed in the arrangement direction. Particularly in the case of fiber materials, the marks of the nails 5 used for temporary fixing are not noticeable and the finish is good. Materials for the backing material 4b include synthetic resins (PVC, PE, EVA), rubber materials (SBR,
A resilient material such as NBR, IR) or asphalt-based material is used, but it is preferable to have a thickness of 2 mm or more, high rigidity in the plane direction, and a certain amount of weight (4 kg/m ² or more). It is more preferable that the material is equipped with the following, since it will fit better into the flooring material 2 after the temporary fixation is released.

Suitable materials for the flooring material 2 include plywood, PB, and IB.

The nail 5 used has an inverted conical spacer 5a as shown in FIG. Spacer 5a
are provided in order to increase the effect of pressing the floor material unit piece 4, but if this is a flat shape, the surface fibers of the surface material 4a made of carpet material or the like will be stuck in a compressed state. Spacer 5 in this example
In the case of a, the lower part is reduced in diameter, so Fig. 3 a,
As shown in b, the pile of the surface material 4a is simply pushed apart to the left and right without being compressed and curled, and even if the surface material 4a is a strip-shaped wooden material, it can be pushed and driven between the strips. Since the tufting interval of carpet material piles is generally 2 mm or more, the outer diameter of the lower part of the spacer 5a is preferably 2 mm or less. The material for the spacer 5a is preferably a relatively elastic material such as synthetic resin (PVC, PP, styrene) or rubber material (SBR, NBR, BR) from the standpoint of not stiffening the fibers of the surface material 4a. be. Moreover, the fact that the spacer 5a is in the shape of an inverted cone makes it easier to grasp the nail 5 when it is removed with pliers or the like, making it easier to release the temporary fixation. The shape of the spacer 5a is not limited to that shown in FIG. 2, but may be the shape shown in FIGS. 4 a to 4 e. What is shown in Figures 4 c to e is
By making the lower end of the spacer 5a spherical, it is possible to more effectively prevent the spacer 5a from curling the fibers of the surface material 4a.

FIG. 5 shows an embodiment in which an elastic body 6, which is softer than the flooring unit piece 4, is previously placed along the wall surface in contact with the flooring unit piece 4 at the periphery of the flooring material. In this example, a baseboard 7 is provided on the wall material 1, and an elastic body 6 is attached to a recessed step 7a formed at the lower end of the baseboard 7.
By performing such treatment, in the work of laying the small pieces 4' obtained by cutting the floor material unit pieces 4 in the peripheral part of the floor area near the wall material 1, the small pieces 4'
Even if there is some error in the dimensions during cutting, the effect of the elastic body 6 allows the small piece 4' to be finished in close contact with the wall surface without any gaps, and also prevents the flooring unit pieces from shifting. It can be prevented.

〔Effect of the invention〕

The flooring construction method of the present invention involves placing a flooring unit piece on a nailable subfloor material as described above, temporarily fixing it with nails that can be easily pulled out from the surface, and surrounding it with boundary material. Since the nails are removed after the nails have been laid over the entire floor, the following effects can be obtained.

(b) Since the flooring unit pieces are temporarily fixed with nails and installed without using adhesives, construction can be carried out quickly without the need to wait for the adhesive to dry as in conventional methods. .

(b) Since adhesive does not stick to the back side of the removed flooring unit piece, it can be easily stored without using release paper.

(c) Even when applied to construction examples where existing flooring is treated as a subflooring material and flooring unit pieces are laid on top of it, there is no problem of adhesive adhering to the existing flooring. , simply by removing the flooring unit piece, the flooring can be restored to its previous state. Therefore, for example, if you lay carpet tiles using the construction method of the present invention on top of a cushion floor in the winter, remove the carpet tiles in the summer, and use the cushion floor as it is, you can This enables new usage patterns.

(d) After installation, the decoration of the floor surface can be easily changed by partially removing it and inserting other flooring materials.
