Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a wooden composite flooring material for construction having a parquet pattern.

Traditionally, wood-based flooring materials that combine natural wood parquet veneer pieces into a parquet mosaic pattern such as a checkered pattern are often used. Due to changes in the parquet veneer pieces, the parquet veneer pieces repeatedly expand and contract, resulting in disadvantages such as gaps being created between them and the parquet veneer pieces easily peeling off.

In addition, the surface is slippery, making it uncomfortable to walk on, and due to manufacturing issues,
After cutting each parquet veneer piece to the specified size, it has to be planed to a high degree of precision, resulting in poor yields.
In addition, it takes a lot of time and effort to assemble it into a parquet pattern, resulting in poor manufacturing efficiency and resulting in high costs.

In order to alleviate these drawbacks, flooring materials have been proposed in which grooves are cut in parquet boards and an elastic material such as rubber is filled in the grooves, as shown in, for example, Japanese Utility Model Publication No. 48-38902.

However, such flooring materials have the drawback that cutting the floor and filling the floor with the elastic material requires a lot of effort, resulting in poor productivity.

This invention aims to solve the above-mentioned problems at once, and as shown in FIG. A parquet flooring material characterized by laminating and adhering elastic material sheets 12 interposed between each other, and then cutting this composite block body A to a required thickness along a plane as shown by the chain line A from which the laminated cross section is obtained. The gist is the manufacturing method.

Therefore, as shown in FIGS. 1 and 2, the flooring material obtained by this invention has elastic material 2 such as rubber interposed between parquet veneer pieces 1 of the required dimensions arranged in parallel. It has a structure in which the parts are bonded and integrated together.

The board material 11 that becomes the parquet veneer piece 1 is made by drying natural wood such as cherry, oak, or teak and cutting it into a predetermined size.The finishing accuracy is relatively rough, and the wood is usually It is not necessary to completely smooth the adhesive surface with a brainer as when gluing.

Further, as the sheet 12 of the elastic material 2, a rubber sheet can be suitably used, but if it is too soft, the paper may become clogged when finishing the surface of the flooring material by sanding, and the abrasive powder may leave fine particles on the wood. On the other hand, if the material is too hard, it will deteriorate the surface slip resistance and cushioning properties of the board material, so it is preferable to use a material with a rubber hardness of 50 to 100 degrees (JIS hardness). be.

As the elastic material 2, in addition to rubber, it is also possible to use elastic synthetic resin, low foaming synthetic resin, or fibrous material such as nonwoven fabric, if necessary.

Furthermore, it goes without saying that the adhesive for bonding the plate material 11 and the elastic sheet 12 should be selected from those that have good adhesion to both materials depending on the type of the object to be adhered to.
When rubber is used as the elastic material sheet 12, an epoxy resin adhesive or a mixture thereof with a rubber resin is preferably used.

If the flooring material cut from composite block A is to be used as a product as is, the surface is roughly ground and then cut into a square or other shape, and if necessary, joining means are provided around the four sides. For example, these are directly pasted on a concrete base surface by arranging them in a checkered pattern.

If there are any unevenness on the floor surface after construction, after the adhesive has hardened, this is corrected with a glider or rough paper, and then finished with a wax finish, oil finish, etc.

In addition, in order to make the flooring material according to the present invention a flooring material with excellent heat insulation properties and a soft walking feeling, a cushioning material 3 such as a rubber sheet or styrofoam is provided on the back side as shown by the chain line in Fig. 2. It may also be used by pasting it on.

Furthermore, the flooring material according to the present invention, especially when it is thin, may be provided as a flooring material that can be installed on a joist foundation by pasting a substrate made of plywood or the like on the back side.

Of course, for example, the thickness of the joist base is 121 mm! ! ?
1! The flooring material according to the present invention may be applied on top of the plywood.

The effects of the present invention configured as described above are as follows.

First, in the flooring material obtained by this invention, even if the parquet veneer pieces expand or contract due to changes in outside air temperature or humidity, the movement is absorbed by the elastic material interposed between them. Because of this, you will never see any trouble occur.

In other words, when the parquet veneer piece contracts, the elastic material expands, so there is no gap at the interface between the two, so there is no risk of dust entering there and damaging the appearance. When it expands,
Since the elastic material is compressively deformed and reduces the pressure applied to the adjacent parquet veneer pieces, defects such as peeling of the flooring material from the underlying surface or substrate surface do not occur.

Second, since the elastic material is exposed on the floor surface, it has excellent slip resistance and provides a good walking feeling.

This means that when grinding and polishing the surface of the flooring material, elastic materials such as rubber are less likely to wear than wood, so the elastic material will protrude slightly from the top surface of the floorboard, and even under use. Wooden parquet veneer pieces wear out faster than elastic materials, so they can maintain good slip resistance over a long period of time.

In order not to impair this anti-slip property, it is desirable to use an oil-based, wax-based, etc. floor finishing agent.

Thirdly, by using an appropriate color such as white or black for the elastic material, it is possible to create an excellent design with a unique appearance.

Fourth, as a manufacturing advantage, it eliminates the traditional manual labor of assembling the parquet, and also eliminates the labor of cutting grooves and filling with elastic material, allowing for highly efficient manufacturing and mass production. Not only is this suitable, but since the elastic material is sandwiched between the sheets of material when they are laminated, the surface finish of the sheets can remain relatively rough, and it is not necessary to make them perfectly smooth. It saves time and labor, and it can greatly improve the yield rate (approximately 8 to 1
It is possible to improve the yield by 0%.

), which in turn can be manufactured and provided at low cost.

Furthermore, fifthly, the flooring material according to the present invention has an elastic material interposed between the parquet veneer pieces and is bonded together, so when it is used as a single piece, the length of the parquet veneer as a whole is perpendicular to the length of the parquet veneer pieces. Possesses considerable flexibility in any direction.

Therefore, even if there are some unevenness on the base surface, it will blend well with the steel surface and the whole can be reliably glued along the base surface.
It is also suitable for direct installation on concrete substrates0
