Description

[Detailed description of the device] (Industrial application field) This device is used not only for general houses but also for stores, large department stores,
It is intended for apartment buildings such as condominiums, and also relates to the improvement of floor material moldings that are currently used, including public buildings such as gymnasiums and meeting places.

(Prior Art) Since flooring materials currently used are artificially dried and have a water content of 13% or less (JAS standard), the area and season to be constructed, downstairs or upstairs, room Depending on conditions such as size and ventilation, considerable contraction is expected. In addition, recently, the quality of wood has been reviewed, and wood floors have come to be used more and more, and all of them are currently constructed by using a floor subassembly or veneer and using an adhesive together. However, the fact that the flooring material is directly stuck on the concrete in this way has a drawback that the floor material is out of order due to absorption of moisture emanating from the concrete and humidity from the surroundings.

(Problems to be solved by the invention) Conventionally, parquets and blocks that are directly pasted on concrete have been used, but due to the above-mentioned drawbacks, so-called flooring board types have the same pasted in the longitudinal direction. It is an object of the present invention to ameliorate this drawback by forming a floor covering to be put in, and to achieve the practical use of a wooden direct-bonding floor covering.

(Means for solving the problem) In a long floor material molded product (1) having a concave-convex portion for fitting formed around it, a fiber board (2) (3) is arranged between the wood veneers (2) (3) arranged in parallel vertically. 4) intervening, and further combining the plate-like foam material (5) under the wood veneer (3) on the side in contact with the surface of the concrete (11), stacking them in order, and adhering them at a fixed interval. Lateral groove provided
By fitting (6) with the concave part (7) and the convex part (8), the semi-broken part (6 ″) provided on the entire circumference where the groove (6 ′) is formed is brought into contact with the concrete (11). The fibrous plate (4) is hard to be dented from the lower side of the foam material (5).

A floor material molded product for direct application to concrete, which has the above-mentioned configuration.

(Function) The fiberboard (4) having a medium specific gravity of the core material used in the long floor molding (1) of the present invention has a heat retaining property.

Also, the adhesive (13) that goes into the groove (6 ') of the uneven fitting part is
Since it extends from the foam material (5) to the fiberboard (4) of medium specific gravity, it is more stable in strength against different materials such as foam material (5), wood veneer on the back surface, and fiberboard (4) of medium specific gravity. It is the one to be confused.

(Example) Hereinafter, an example of the present invention will be described.

(A) Long floor material molded product with irregularities for fitting formed around
In (1), 5 mm MD is placed between wood veneers (2, 3) with a thickness of 2 mm, such as beech, oak, and hippo arranged in parallel vertically.
A fiber board (4) such as F fiber board (trade name) is interposed, and an adhesive (for example, KR-138L.AJ-2 trade name) is used for adhesion. (B) Furthermore, concrete (11) A plate-like foam material (5) such as Lion board F (trade name) 2 mm is combined with the lower side of the wood veneer (3) on the side in contact with the surface, for example, KR-1.
20. Using an adhesive such as AG (trade name) to stack and adhere in order (C), and by fitting the lateral groove (6), the recess (7), and the protrusion (8) at a fixed interval, From the bottom of the foam material (5) in contact with the concrete (11), insert the semi-broken part (6 ″) provided on the entire circumference of the long floor material forming product (1) where the groove (6 ′) is formed The board (4) is formed with a hard dent, and (d) When the adhesive (13) is attached to the concrete (11), while the adhesive (13) is intruding into the lateral groove (6) and the groove (6 '). A floor material molded product for direct-adhesion of concrete, which can be appropriately arranged and adhered to the uneven curved surface of the concrete (11), and has waterproofness and elasticity.

If the width of the long floor molding (1) is 75 mm, the length is 600 mm and 900 m.
m Thickness is 11 mm. And wood veneer at that time (2)
The thickness of (3) is 2 mm, the thickness of the fiberboard (4) is 5 mm, and the thickness of the foam material (5) is 2 mm. The width of the lateral groove (6) is 2.5 mm, the depth is 7 mm, and the interval is 100 mm.
Since the groove (6 ') is formed with the semi-broken portions (6 ") facing each other, the depth thereof is about 5 mm and the width is 2 mm.

(Effects of the Invention) According to the present invention, a special groove (6 ') formed by combining flooring on the four side surfaces of a narrow floor molding (1) and lateral grooves (6) at regular intervals. ) Causes shrinkage and expansion of the floor surface within a small area of the molding floor board surrounded by both grooves. It's so small that it doesn't become too big, and it has the effect of being able to hold it down.

Further, the groove (6 ') and the lateral groove (6) on the four side surfaces of the long floor molded article (1) are filled with the adhesive (13) when the adhesive is applied to the concrete (11) floor slab. Since the bonding is performed from the four side surfaces of the molded floor plate divided by the groove, the effect that the bonding work can be performed more strongly than that of the conventional direct bonding floor plate only when the bonding work is performed.

On the other hand, the moisture-proof sheet on the back side of the molded floorboard, the backside veneer (wood),
The peeling phenomenon that tends to occur in each adhesive layer of the base material MDF (fiber board of medium specific gravity) is adhesively fixed from the four side surfaces with the adhesive filled in the four side surface grooves for each small area divided by the groove. Therefore, it is possible to obtain the effect that the pressure can be sufficiently suppressed.

In addition, in order to improve the impact sound to the downstairs of condominiums, which has become a problem these days, a fiberboard of medium specific gravity is used in the center of the flooring to absorb the sound and a foam material is attached to the back surface. By increasing the sound insulation effect.

In addition, the foam material has excellent heat retention and heat insulation properties, and has appropriate cushioning properties.
