DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] Floorboards constructed directly on floor bases used in houses.

[0002]

2. Description of the Related Art Conventionally, floorboards in which an arbitrary makeup is applied to the surface of the substrate, the actual processing is applied to four edges thereof, and a lightweight body such as foamed rubber or foamed synthetic resin is adhered to the back surface of the floorboard. Provided.

By the way, a lightweight body adhered to this kind of floorboard acts as a cushioning body, and is resistant to an impact applied to the floorboard surface, particularly an impact due to a drop of a spoon, a marble or the like (generally referred to as a lightweight impact sound). It works effectively. In addition, the floorboard itself is directly constructed on a floor substrate such as a concrete slab, a plywood, a wood fiber board, a particle board, and a cement board via an adhesive.

[0004] However, this kind of floorboard quickly sinks into a lightweight body immediately against the impact applied to the floorboard surface or the impact when a child jumps (generally referred to as a heavy impact sound). It is propagated to the floor basement and has no effect. In addition, since the entire construction is performed by bonding, it is difficult to change the tension, which requires a lot of construction work.

[0005]

[Technical Means] In a floorboard in which makeup is applied to the surface of a substrate and the actual processing is performed on four edges thereof, a heavy sheet having the same area and the same shape as the rear surface is provided on the back surface in the length direction of the substrate. A floor plate which is laminated so as to form a tongue portion by being shifted by an arbitrary width, and provided with an adhesive layer having release paper on the surface of the tongue portion.

[0006]

[Structure] The structure of the floorboard of the present invention will be described below. Makeup o is applied to the surface of the substrate 1 as shown in FIG. The substrate 1 may be a plywood, a wood fiber board, a particle board, a flake board, a strand board, a wafer board, a wood stick board, a veneer laminated material, a laminated material alone, or a composite material obtained by optionally laminating them. Good.

[0007] Cosmetic o is applied to the surface of the substrate 1 which has been subjected to base treatment such as sealing, sealing, sanding or the like as necessary, by applying a colored coating, pattern printing, or an adhesive to decorative paper, decorative synthetic resin. It is performed by sticking a decorative sheet such as a sheet, a synthetic resin-impregnated paper, a nonwoven fabric, a wood board, an artificial wood board, a cork sheet, a cloth, and a metal foil.

The four edges of the substrate 1 are subjected to actual processing of male and female dies 2b and 2a at the opposite corners as shown in FIGS. The actual processing may be performed before the makeup o is applied to the surface of the substrate 1 or after the makeup o is applied.

The substrate 1 may be provided with a plurality of grooves 6 having a depth of at least half the thickness of the substrate 1 on its surface. When the substrate 1 itself is thick, has a high specific gravity, or has high rigidity due to the physical properties of the material itself, the groove 6 on the back surface reduces the rigidity (weaks the waist). Better to absorb irregularities. The groove 6 on the back surface may be formed in a certain direction parallel to the opening, or may be formed so as to cross in parallel with the opening, or may be formed so as to be oblique to the opening or in parallel with the opening. It may be formed in a shape.

[0010] The groove pitch may be arbitrarily set, but is preferably set at a pitch of 10 to 30 mm and the groove width is set to 5 mm or less. The depth of the groove 6 is required to be at least half the thickness of the substrate 1 and does not divide the substrate 1 itself.

Alternatively, in consideration of the strength of the floor plate, the grooves 6 near the wood opening formed in a plurality of rows may be formed to be the shallowest and deeper as the inner rows are formed. Or you may provide a groove | channel from arbitrary inside from a kiguchi. By doing so, actual fitting at the time of construction can be easily performed without lowering only the rigidity near the kiguchi real parts 2 and 2.

On the back surface of the substrate 1 having a groove 6 formed on the back surface,
The heavy sheet material 3 is laminated via the adhesive C. The heavy sheet material 3 has the same area and the same shape as the back surface of the substrate 1, and is stacked so as to form the tongue portion 5 by being shifted by an arbitrary width in the length direction of the substrate 1.

As shown in FIG. 4, an adhesive layer 4a having a release paper 4 is provided on the surface of the tongue 5. The heavy sheet material 3 has a thickness smaller than the thickness of the substrate 1, and a laminate formed by laminating the substrate 1 and the heavy sheet material 3 weighs 1.5 times or more the substrate weight. Is used. Therefore, the specific gravity of the heavy sheet material 3 is preferably 1.5 or more.

If the specific gravity is 1.5 or less, the weight sheet 3 itself becomes too thick to make the substrate weight 1.5 times or more, and the floorboard itself becomes too thick, resulting in poor workability. Furthermore, the rigidity is high, and it is hard to be blended with the floor substrate and cannot absorb irregularities.

By setting the weight to 1.5 times or more the weight of the substrate, the substrate having reduced rigidity adapts itself to the floor substrate by its own weight, thereby absorbing irregularities. Further, since the floorboard becomes heavy, it is possible to prevent the slippage of the floorboard during the walking after construction.

The heavy sheet material 3 may be a synthetic resin sheet, a natural or synthetic rubber sheet, an asphalt sheet, or a sheet material such as paper, cloth, non-woven fabric, or the like.
A sheet-like material obtained by singly impregnating paper or the like impregnated with asphalt or the like or arbitrarily laminating them is used.

The heavy sheet 3 preferably has a solid friction coefficient of 0.3 to 0.6 at room temperature and atmosphere when two sheets are used, for example, when they are superposed. Prevents sliding movement of the floorboard at the time. The heavy sheet material 3 may optionally be mixed with a heavy substance powder having a specific gravity of 2 or more, such as a metal powder or a ceramic powder, if necessary. The heavy sheet material 3 has viscoelasticity, and when a heavy impact is applied to the floor plate surface, the heavy sheet material 3 can absorb the shock by shear deformation.

Further, as shown in FIG. 5, a caulking agent k is provided in the groove of the female nut 2a at the bottom of the groove. The caulking agent k is preferably one having tackiness, which ensures the actual bonding between the floorboards and also prevents moisture from the floor substrate from entering the room through the real bonding portion. In this manner, the sheet-like material 3 having the same area and the same shape as the rear surface is laminated on the rear surface thereof so as to be shifted by an arbitrary width only in the direction of one side of the opening, and the tongue portion 5 is formed. The floor board provided with the adhesive layer 4a having the following was obtained.

The construction of the floorboard is performed as follows. First, the floorboard is placed at a predetermined position on the floor substrate. Next, the release paper 4 on the tongue 5 of the heavy sheet material 3 is removed to remove the adhesive layer 4a.
To expose. Next, as shown in FIGS. 3A and 3B, the floorboards to be constructed adjacent to each other are attached to the tongues 5 of the previously constructed floorboard heavy sheet material 3 with the portions where the heavy sheet material 3 is not laminated on the back side. , 2b are fitted and overlapped. By repeating this, one row is connected.

Further, as shown in FIG. 3c, a second row of floorboards is placed on the side of the row of connected floorboards while fitting the respective floorboards, and thereafter the same procedure is repeated as in the first row. By repeating this, a floor board is laid on the floor substrate. Figure 6 is male
The front view of b side is shown. FIG. 7 shows a stepped male and female fruit 102b, 1 forming a stepped joint as the floorboard 101 of the present invention.
02a and a stepped tongue 105 are shown. Tongue 1
At 05, an adhesive layer and a release paper are applied in the same manner as in FIG.

[0021] The floorboard is laid while absorbing unevenness of the floor substrate by its own weight, and is constructed without using nails or glue. In addition, since nails and glue are not used in the construction, expansion and contraction due to moisture absorption of the floor plate works as the whole floor surface, so at least in the side wall direction of one side of the indoor floor plate, one side side direction, the lower part of the baseboard provided on the wall A gap for absorbing the expansion and contraction of the floorboard is provided, or a foaming material is inserted in the gap to create an absorption section for the expansion and contraction of the floorboard.

[0022]

【The invention's effect】

{Circle around (a)} The floorboard is provided with the heavy sheet material 3 on the back surface, which itself is heavy and hard to move when constructed on the floor substrate.

(B) Construction can be carried out only by actually fitting and laying without using nails or glue, and the floorboards are connected by an adhesive layer 4a provided on the tongue 5 of the heavy sheet material 3. As described above, since the floor foundation is constructed without using nails or glue, it can be easily replaced and the like.
