[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floorboard in which a cushioning material is attached to the back surface of a floor base material and is adhered to a floor base.

[0002]

2. Description of the Related Art A floor plate having a sheet-like or plate-like synthetic resin, rubber or synthetic rubber, or a foamed material thereof, a fibrous material sheet or plate or the like cushioning material adhered to the back surface of a floor base material. It has been provided conventionally.

[0003] In such a floorboard, after applying an adhesive to the floor base surface, a first floorboard is first constructed, and then a real part (male or female) of the floorboard to be constructed adjacent to the first floorboard is applied. It is constructed so as to be shifted in the lateral direction while being fitted to the real part (female or male) of the horn.

[0004]

However, in this kind of floorboard of the related art, a cushioning material is stuck over the entire back surface. The adhesive applied in advance to the floor base surface is scraped off by the edge portion of the cushioning material. The amount of the adhesive that has been scraped will protrude to the surface when the floorboards are abutted against each other, impairing the appearance as a decorative floor surface,
Was causing contamination.

[0005]

Accordingly, the present invention solves the above-mentioned drawbacks of the prior art, and provides a floor plate in which the adhesive does not protrude to the surface even when the floor plates are shifted side by side through actual fitting. The purpose is to provide.

That is, the floorboard according to the present invention is a floorboard in which a cushioning material is adhered to the back surface of a floor substrate.
The lateral direction end portion is provided so as to retreat inside the lateral direction end portion of the floor base material.

[0007] The floor base material is appropriately selected and used from common wood base materials such as plywood, particle board, hard board, and veneer laminate (LVL, LVB).

The floor substrate is formed by laminating a plurality of these plate-like bodies,
A known cushioning material or sound insulating material (for example, a sheet- or plate-shaped synthetic resin, rubber or synthetic rubber, a foam thereof, or a mixture of these with a metal powder or a ceramic powder) is sandwiched between arbitrary layers. As an alternative, the sound insulation and sound insulation may be improved.

A plurality of grooves extending in a predetermined direction can be formed on the back surface of the floor base material, thereby reducing the rigidity of the floor base material, improving the compatibility with the floor base, and improving the front surface. The effect of absorbing the impact energy applied to the floor substrate can be provided. In addition, since the floor base material is divided by the grooves on the back surface, propagation of sound is prevented, which contributes to further improvement of the soundproofing effect.

[0010] The surface of the floor substrate can be optionally decorated. For example, makeup is applied by laminating and bonding a surface decorative material such as a veneer, a synthetic resin or a synthetic resin foam decorative sheet, decorative paper, or a synthetic resin impregnated decorative paper to the surface of the floor base material. In addition, after subjecting the floor substrate surface to any underlying treatment,
Painting or pattern printing may be applied.

[0011] Actual processing such as actual cutting is performed on two sides of the edge of the floor substrate extending in the longitudinal direction or around four edges of the edge extending in the longitudinal direction and the lateral direction.

The cushioning material to be adhered to the back surface of the floor substrate is a sheet- or plate-shaped synthetic resin, rubber or synthetic rubber, or a foam or a fiber material sheet, which is conventionally used. Alternatively, it may be made of a plate or the like. These may be used alone or, if necessary, may be used by laminating a plurality of sheets. Specific gravity of cushioning material,
Physical properties such as expansion ratio and elasticity are appropriately selected and determined as needed.

[0013] Such cushioning material, rather than being stuck over the conventional back surface general flooring substrate as in the present invention, the short-side direction end of the widthwise direction end portions floor base It is stuck so as to retreat inside the part .

In other words, the inner retreating end of the cushioning material is
As corresponding to the end extending in the longitudinal direction of the base material,
At least one of them is provided. The reason for this is that
Adhesive on the floor base may be touched by the edges of the cushioning material during skidding.
The phenomenon of scraping off is caused by the floor material edge that extends in the longitudinal direction.
This is because it appears more prominently when the parts meet.
You. In addition, the joint at the end in the longitudinal direction is
The force of contraction and expansion accompanying the
For such a case, it is necessary to provide such an inner retreat end on the cushioning material.
Infiltration of adhesive into joints during construction
It is considered preferable to improve the strength by
You.

The inner receding end of such a cushioning material may be formed in advance on the cushioning material and adhered to the back surface of the floor substrate, or may be formed over the entire back surface of the floor substrate. Alternatively, after attaching the cushioning material of the same shape, the peripheral portion may be cut out in an arbitrary shape.

[0016]

FIG. 1 is a cross-sectional view of a floor board 1 according to an embodiment of the present invention in a lateral direction. A notch step 5 between the end portion extending in the longitudinal direction (perpendicular direction of the paper) of FIG.
a and 5b are arranged, and a cushioning material 4 having a size slightly smaller than the floor base material 2 is attached. On the floor substrate 2, a male nut 2a and a female nut 2b extending in the longitudinal direction are formed.

FIG. 2 shows a state in which such floorboards 1 are constructed on a floor base 6. Male 2a formed on floor substrate 2
The floorboards 1 are connected to each other through the fitting between the female nuts 2b and the female members 2b. At this time, an adhesive (not shown) previously applied on the floor foundation 6 is applied to the cushioning material 4 by the side slip. It is scraped off by the edge. However, as is apparent from the drawing, the space 7 is provided between the cushioning materials 4 and 4 even when the floor plates 1 and 1 are abutted by the formation of the cutout steps 5a and 5b. Since the adhesive functions as a pool, the scraped adhesive does not protrude to the surface side of the floor plate 1.

FIGS. 3 to 5 show some modifications of the shape of the inner retreating end of the cushioning member 4. FIG.

[0019]

According to the floorboard of the present invention, the short-side end of the cushioning material adhered to the back surface of the floor base is the short-side end of the floor base.
Since it is provided so as to recede inward from the part , in such a state that the floorboards abut each other, a space formed by the inner receding end of the cushioning material is formed on the floor substrate, and on the floor substrate on which the adhesive is applied. The adhesive that is scraped off when the construction is performed while the floorboards slide sideways is accommodated in this space, and does not protrude to the surface side, so that a beautiful construction floor surface can be obtained.

Further, even after the application, if energy is applied from the surface of the floorboard before the adhesive is solidified, the cushioning material expands in the lateral direction when absorbing shock, thereby causing the adhesive to be expanded. Although it may protrude to the surface side, when the construction is performed using the floorboard of the present invention, the above-mentioned space is formed. The protrusion phenomenon is avoided.
