To form.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a floor board having a cushioning material adhered to the back surface of a floor base material and bonded on a floor base.

[0002]

[Prior Art]

 Conventionally, there is a floorboard in which a cushioning material made of a sheet-shaped or plate-shaped synthetic resin, rubber or synthetic rubber, or a foamed material thereof, a fiber material sheet or a plate is attached to the back surface of the floor substrate. It is provided.

In such a floorboard, after the adhesive is applied to the floor base surface, the first floorboard is first constructed, and then the real part (male or female) of the floorboard to be adjacently constructed is the previous floorboard. It is installed by fitting it with the real part (female or male) and shifting it laterally.

[0004]

[Problems to be solved by the device]

 However, in this type of conventional floorboard, since the cushioning material is adhered over the entire back surface of the floorboard, when the above-mentioned construction method is used, the edge of the cushioning material causes the floorboard surface to be displaced during the horizontal displacement. The adhesive that has been applied in advance is scraped off. This scraped off adhesive would stick out to the surface when the floor boards were butted against each other, impairing the appearance as a decorative floor surface and causing contamination.

[0005]

[Means for Solving the Problems]

 Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a floor plate in which the adhesive does not stick out to the surface even when the floor plates are laterally placed for construction by actual fitting.

That is, the floorboard according to the present invention is one in which a cushioning material is attached to the back surface of the floor base material, and the end portion of the cushioning material is set back inside the end portion of the floor base material. It is characterized by being

The floor base material is appropriately selected and used from commonly used wood base materials such as plywood, particle board, hard board, and single plate laminated board (LVL, LVB).

The floor base material is formed by laminating a plurality of layers of these plate-like bodies, and a known cushioning material or sound insulating material (for example, sheet-like or plate-like synthetic resin, rubber or synthetic rubber, foams thereof, etc.) between arbitrary layers. Alternatively, a mixture of metal powder, ceramic powder, etc.) may be sandwiched between them to improve soundproofness and sound insulation.

A plurality of grooves extending in a predetermined direction can be engraved on the back surface of the floor base material, which reduces the rigidity of the floor base material and improves the compatibility with the floor base material. At the same time, the impact energy applied to the surface can be absorbed in the floor base material. Further, since the floor base material is divided by the groove on the back surface, the propagation of sound is prevented, which contributes to the further improvement of the soundproof effect.

An optional make-up can be applied to the surface of the floor base material. For example, makeup is applied by laminating and adhering a surface decorative material such as a veneer, a synthetic resin or a synthetic resin foam decorative sheet, a decorative paper, and a synthetic resin-impregnated decorative paper to the surface of the floor base material. It is also possible to subject the floor base material surface to an optional undercoating treatment and then to apply painting or pattern pattern printing.

[0011] Actual processing such as fruit is applied to the two sides of the mouth end extending in the longitudinal direction of the floor base material or around the mouth end 4 extending in the longitudinal direction and the lateral direction.

The cushioning material attached to the back surface of such a floor base material is a sheet-like or plate-like synthetic resin, rubber or synthetic rubber, or a foam or fiber thereof, which has been conventionally used. It may be made of a material sheet or plate. These may be used alone or, if necessary, used by laminating and adhering a plurality of sheets. Physical properties such as specific gravity, expansion ratio and elasticity of the cushioning material are appropriately selected and determined as necessary.

Such a cushioning material is not adhered over the entire back surface of the floor base material as in the conventional case, but in the present invention, its end portion is located inside the end portion of the floor base material. It is attached so as to move backward.

The inner recessed end of the cushioning material is preferably provided on at least one of the ends corresponding to at least the end extending in the longitudinal direction of the floor base material. The reason for this is that the phenomenon in which the adhesive on the floor base surface is scraped off by the edges of the cushioning material during the sideslip of the floorboard is more prominent when the edges of the floor base materials that extend in the longitudinal direction are brought into contact with each other. Is. However, more preferably, at least one of the ends extending in the longitudinal direction and at least one of the ends extending in the latitudinal direction are respectively retracted inward from the corresponding ends of the floor base so that the inner retracted end is formed. Part.

The inner retreat end of such a cushioning material may be formed in advance as a cushioning material and then attached to the back surface of the floor base material, or over the entire back surface of the floor base material. Alternatively, the cushioning material having the same shape may be attached, and then the peripheral edge portion may be cut out into an arbitrary shape.

[0016]

【Example】

 FIG. 1 is a cross-sectional view of a floorboard 1 according to an embodiment of the present invention, in which a decorative material 3 is attached to the entire surface of a floor base material 2 and a longitudinal direction of the floor base material 2 is applied to the back surface. A cushioning material 4 having a size slightly smaller than that of the floor base material 2 is attached by arranging notched step portions 5a and 5b between the end portion extending in the (paper surface vertical direction). The floor base 2 is formed with male seeds 2a and female seeds 2b extending in the longitudinal direction.

FIG. 2 shows a state in which such floor boards 1 are constructed on a floor base 6. The floorboards 1 are laterally spliced through the fitting of the male seeds 2a and the female seeds 2b formed on the floor base material 2, and the lateral slip at that time causes the adhesive to be applied on the floor base 6 in advance. The agent (not shown) is scraped off by the edge portion of the cushioning material 4. However, as is clear from the drawing, the formation of the cutout step portions 5a and 5b provides a space 7 between the cushioning members 4 and 4 even when the floor boards 1 and 1 are butted against each other, and the space 7 is formed by the adhesive. Since it functions as a pool, the scraped adhesive does not overflow to the surface side of the floorboard 1.

3 to 5 show a slight modification of the shape of the inner receding end portion of the cushioning member 4.

[0019]

[Effect of the device]

 According to the floorboard of the present invention, since the end portion of the cushioning material attached to the back surface of the floor base material is provided so as to recede inward from the end portion of the floor base material, such floorboards are abutted to each other. In this state, a space is formed on the floor base by the inner receding end of the cushioning material, and the adhesive that is scraped off when the floor boards to which the adhesive is applied is scraped off while the floor boards are slid together is stored in this space. Therefore, a beautiful construction floor can be obtained without protruding to the surface side.

Further, even after the construction, if energy is applied from the surface side of the floorboard before the adhesive is solidified, the cushioning material expands laterally when the shock is absorbed, which causes The adhesive may squeeze out to the surface side, but when the floorboard of the present invention is used for construction, the space as described above is formed, and the expanded portion of the cushioning material is received in this space. As a result, the phenomenon of adhesive sticking out is avoided.
