Abstract

PURPOSE:To improve the construction performance by decoration-finishing a surface and attaching a plurality of wooden pieces on which a number of grooves are formed on the reverse surface side in parallel arranged state on a soft sheet. CONSTITUTION:Wooden decoration plates 4 are laminated on a wooden basic plate 5 made by plywood, and a wooden piece 1 formed on the reverse surface of the basic plate 5 by arranging a number of grooves 3 nearly in parallel. Then, a wooden floor member A is constituted by arranging and attaching a number of pieces 1 on a soft sheet 2 such as vinyl-chloride resin sheet. The rigidity of the piece 1 is drastically reduced, and flexibility is provided, and the adaptation to a floor substrate is improved. Accordingly, the construction performance and finishing performance can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a wooden floor material that is laid directly on a subfloor finished with mortar, concrete, etc. This relates to technology that aims to suppress this, reduce rigidity to a large extent, provide flexibility, facilitate transportation and handling, improve workability, and facilitate dimensional correction.

[Prior Art] As shown in FIG. 6, a wood carpet-like wooden flooring material A in which long wooden plywood boards 1a are connected in a bendable manner has heretofore been produced.
It has been known.

[Problems to be Solved by the Invention] By the way, the wooden flooring material A using the long wooden plywood 1a tends to warp in its length direction, and
Due to its high rigidity, it is difficult to adapt to subfloors such as concrete slabs and panel panels, and therefore, during construction, it must be fixed with nails or adhesives. Not only does the construction become troublesome and the maintenance work is also difficult, but the wooden flooring material A in the form of a wood carpet has problems such as being large and cumbersome to transport and handle, and difficult to perform detailed cutting. there were.

The present invention was made in view of such problems,
The purpose of this is to significantly reduce the rigidity of wooden flooring materials, provide visibility, and improve adhesion to the subfloor, avoiding the need for nailing or adhesive installation. The object of the present invention is to provide a wooden flooring material that has significantly improved workability and maintenance, is easy to transport and handle, is easy to modify in detail, is easy to process, and is easy to cut, and can improve workability. .

[Means for Solving the Problems] The wooden flooring material of the present invention has a plurality of wooden pieces 1, each having a decorative finish on the surface and a plurality of grooves 3 formed on the back side thereof, arranged side by side on a soft sheet 2. It is characterized by being attached in a fixed state.

[Function] In this way, a plurality of wooden pieces 1 each having a decorative finish on the surface and a large number of grooves 3 formed on the back side are attached to the soft sheet 2 in parallel, so that the back side The rigidity of the wooden pieces 1 can be greatly reduced in the large number of tl 13 on the side, and rather flexibility can be imparted, allowing good adaptation to the subfloor, and these wooden pieces 1
A large number of yII? are pasted on the soft sheet 2? ! -By being able to
The flexibility of the wooden flooring material A is made sufficient, - it is made to conform well to the layered floor substrate, and the workability is improved by avoiding the need for nailing or adhesive work, and moreover, it is possible to create a large number of By pasting the wooden piece 1 on the soft sheet 2, the shape of the wooden flooring material A is changed, making it easier to transport and handle.
The mfIS can be repaired and cut, and workability and finish quality are improved in this respect as well.

[Example] Embodiments of the present invention will be described in detail below based on the drawings.

A wooden decorative board 4, such as a veneer (sliced veneer) made by thinly slicing wood and having a butt end, is laminated and bonded to a wooden substrate 5, and the wooden substrate 5 is made of plywood, and the plywood is made of 3-ply, 5-ply wood.
A material such as ply or 7 ply is used. On the back side of the wooden substrate 1, grooves 3 are formed with a saw blade or the like and are arranged in parallel in parallel. This groove 3 is 1.6--3.
2 ■ Medium grooves, the spacing between grooves 3 is 5, Oal
The length is approximately 1 to 30 mm. The number of questions is most preferably about 10, and the grooves 3 may be formed vertically and horizontally. The wood piece 1 thus formed has a vertical dimension of 16
The length is about 6.6m, the horizontal dimension is about 83.3m, and the thickness is about 5mm. The soft sheet 2 is, for example, a vinyl chloride sheet, or may be a non-backed sheet with metal powder mixed therein, and its thickness is about 1-1. Then, a large number of wooden pieces 1 are arranged side by side and laminated and adhered to a soft sheet 2 to constitute a wooden flooring material A. The horizontal dimension of the wooden floor material A is approximately 300 m, and the vertical dimension is approximately 1800 mm. Some of these external dimensions are as small as about 150wm x 900mm. Further, the external shape can also be modified as shown in FIG.

In this way, a plurality of wooden pieces 1, each of which has a decorative finish on the surface and a large number of grooves 3 formed on the back side, are attached to the soft sheet 2 in parallel, so that a large number of grooves 3 are formed on the back side. The rigidity of the wooden piece 1 in the groove 3 of the book is greatly reduced to suppress warpage 1, but rather it imparts flexibility. This allows it to blend well with the flooring. By adhering a large number of these wooden pieces 1 to the soft sheet 2, the flexibility of the wooden flooring material A is made sufficient, and - it is made to conform well to the layered flooring base. In this way, floor construction is carried out in which the wooden flooring material A is directly installed on the cocrete or mortar-finished floor base 6, which avoids the need for nailing or adhesive construction and enables direct laying construction. It is. Moreover, by attaching a large number of wooden pieces 1 to the soft sheet 2, the shape of the wooden flooring material A can be changed, transportation and handling can be facilitated, and detailed finishing and cutting can be performed.

By the way, the soft sheet 2 is a mixed sheet in which a high specific gravity substance such as valium sulfate, pyrolysium bicarbonate, lead powder, copper powder, etc. is mixed into a base material such as polyethylene, EVA, urethane, natural rubber, etc. is preferably 1.0 or more, that is, about 1.5 to 3.0, and
A wood base with a higher specific gravity than that of the wooden base @5 is used. However, by using such a soft sheet 2 with a high specific gravity, it can be laid so that it blends in with the flooring 6 such as a concrete slab or a control panel, and it can be laid easily with the flooring 6 without nailing or using adhesives. This increases the coefficient of friction and allows direct installation.

[Effects of the Invention 1] In summary, the present invention has a plurality of wooden pieces each having a decorative finish on the surface and a plurality of grooves formed on the back side thereof, which are attached to a soft sheet in parallel. The rigidity of the wooden piece can be greatly reduced through the numerous grooves on the back side, suppressing warping and, in fact, imparting flexibility, allowing it to fit well into the subfloor. Since a large number of wooden pieces are attached to a soft sheet, the flexibility of the wooden flooring material is sufficient, and it is well adapted to the base material, making it easy to install with nails or adhesives. In addition, since a large number of wooden pieces are attached to a soft sheet, the shape of the wooden flooring material can be changed, making it easier to transport and handle, and allows for detailed finishing and cutting. This also has the advantage of improving workability and finish quality.
