Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved wooden decorative flooring material to be installed on a flooring material.

[0002]

2. Description of the Related Art Conventionally, in order to construct a wooden flooring material on a flooring panel such as a plywood or a flooring material such as a concrete slab, the back surface of the wooden decorative flooring material is adhered to the flooring surface with an adhesive. A method of laying, a method of using nails or nails and an adhesive in combination, or forming a hook-like male and female part on the four end faces of the wooden decorative flooring material, and the male and female of the adjacent wooden decorative flooring material There is widely known a method of directly installing without using an adhesive while engaging a real part, and a method of using a double-sided adhesive tape.

[0003]

However, according to the method of constructing a wooden decorative floor material on a floor substrate using an adhesive, when the wooden decorative floor material is placed on the floor substrate, the position of the wooden decorative floor material is immediately determined by the adhesive. It is difficult to align the wooden decorative flooring with the already laid wooden decorative flooring because the wooden decorative flooring is displaced, and it requires skill to accurately perform floor construction. There is a problem of deteriorating the indoor environment. On the other hand, in the method of performing construction by nailing a wooden decorative floor material to a floor base material, once nailed, it is difficult to re-attach.

In addition, according to the wooden decorative floor material having the hook-like male and female parts formed on the four end surfaces of the wooden decorative floor material, the shape of the hook-like female and male parts is complicated, so that the resin is formed by resin molding. The male and female parts must be formed beforehand and attached to the end face of the wooden decorative flooring material, resulting in a problem of high cost. Such a problem can be solved by the method of applying the wood decorative floor material using a double-sided adhesive tape, but the release paper covering the adhesive layer is difficult to peel off at the time of application, or the adhesive is applied at the time of application. When the agent layer adheres to the floor base material, it becomes difficult to shift the wooden decorative floor material along the floor base surface in the same manner as in the construction method using the adhesive, and the male and female real parts with the already laid wooden decorative floor material become difficult. However, there were problems such as that the joining of the pieces could not be performed reliably, that a gap was formed and that accurate construction was difficult.

[0005] The present invention has been made in view of such problems, and it is an object of the present invention to easily correct deviations during construction, causing irregularities and gaps. It is an object of the present invention to provide a decorative wooden flooring material that can easily and accurately perform construction without any difficulty.

[0006]

In order to achieve the above object, the wooden decorative flooring material of the present invention has a structure in which both ends are formed on the lower surface of a flooring material mainly made of a rectangular wooden board. A wood-based decorative material in which concave grooves that are opened on both long side end surfaces of the floor material are engraved at predetermined intervals in the length direction of the floor material and real parts are formed on four end surfaces of the floor material. The adhesive layer is provided on both the upper and lower surfaces, and the net-like substance to be adhered to the lower adhesive layer, at least the lower half of the net-like substance in the thickness direction is projected from the lower surface of the adhesive layer, and the adhesive is applied. The upper pressure-sensitive adhesive layer of the double-sided pressure-sensitive adhesive tape that is immersed in the pressure-sensitive adhesive layer is adhered to the back surface of the floor material, and the lower pressure-sensitive adhesive layer is covered with release paper.

According to a second aspect of the present invention, in the wooden decorative flooring material according to the first aspect, a double-sided adhesive tape is attached to both sides of the long side of the back surface mainly of the flooring material over the entire length. In addition, the ratio of double-sided adhesive tape to the floor area is 20 to 70%.

[0008]

When the wooden decorative floor material is applied to the flooring material, first, the release paper of the double-sided adhesive tape attached to the back surface of the wooden decorative floor material is peeled off. At this time, the net-like material was on the lower pressure-sensitive adhesive layer to which the release paper of the double-sided pressure-sensitive adhesive tape was attached, and at least the lower half in the thickness direction of the net-like material was projected from the lower surface of the pressure-sensitive adhesive layer. Since it has a structure in which a part of the release paper is adhered to the pressure-sensitive adhesive layer via the net-like material, the release paper can be easily and smoothly peeled from the pressure-sensitive adhesive layer. .

After the release paper has been peeled off, the wooden decorative floor material is placed on the portion of the floor base material to be constructed with the pressure-sensitive adhesive layer of the double-sided pressure-sensitive adhesive tape facing downward, and the pressure-sensitive adhesive layer is directly applied to the floor base material surface. The lower surface of the net-like material protruding from the pressure-sensitive adhesive layer abuts the floor base material without adhering. Therefore, it is possible to easily correct the deviation of the wooden decorative flooring while sliding the net-like object on the surface of the floor base material, and the actual connection with the existing wooden decorative flooring is performed accurately and the accuracy is improved. Good floor construction is possible.

[0010] Furthermore, since the wood floor is mainly provided with concave grooves penetrating over the entire width thereof at small intervals in the longitudinal direction, warpage due to absorption and moisture release is unlikely to occur. Not only that, it exhibits good flexibility and flexibility together with the double-sided pressure-sensitive adhesive tape, has good familiarity with the floor base surface, and can eliminate irregularities and steps. In this way, after the wooden decorative floor material is placed on the floor substrate and the position is adjusted, when the upper surface of the wooden decorative floor material is pressed and pressed against the floor substrate, the net-like material is pushed into the adhesive layer. When it is immersed, the pressure-sensitive adhesive layer is completely adhered to the floor base material, and strong fixing is performed.

Further, when the wooden decorative flooring material is pressed against the floor base material, the double-sided adhesive tape exerts a cushioning action to absorb irregularities, and is easily connected to the existing wooden decorative flooring material.

[0012] In the wooden decorative flooring according to claim 1, in order to stick the wooden decorative flooring so as to be securely fixed on the floor substrate, a double-sided adhesive tape with respect to the area of the flooring main body. Is preferably set to 20 to 70%, and furthermore, the double-sided adhesive tape is stuck on both sides of the long side of the back surface mainly of the flooring material over the entire length thereof. Can be prevented from being excessively bent or refracted from the grooves perpendicular to all the grooves mainly composed of the floor material, and breakage of the wooden decorative floor material at the time of handling or the like can be prevented.
