Description

TECHNICAL FIELD The present invention relates to a wooden floor material.

In this specification, "sound insulation" refers to floor impact sound insulation performance.

Problems to be Solved by Conventional Technology and Invention Conventionally, in high- and medium-rise houses, it has been common to directly attach carpets as floor surface materials to the floor base. However, not only is carpet difficult to maintain,
Since it takes time and labor to replace the carpets, there is a tendency in recent years to replace wood carpets with wood flooring materials directly on the floor base.
However, the wooden flooring material has a drawback that it is inferior in habitability because it has a significantly lower sound insulating property than carpets.

To solve this problem, a foam may be attached to the entire lower surface of the wooden board, and a floor material having such a structure has already been disclosed in Japanese Utility Model Laid-Open No. 56-3945.

By the way, when arranging and fixing a large number of floor materials on the floor base material in a continuous state in the front, rear, left, and right, a bonding method is usually used.
The bonding method uses known adhesives such as epoxy resin type and vinyl acetate resin type, put a sand bag on the floor material until the adhesive material hardens, and commonly call it "burr" between the floor material and the ceiling. The work is poor because it is done by applying a pressure to the floor material by using a small bar called "." There are also attempts to use adhesives for flooring construction. The pressure-sensitive adhesive has a strong instantaneous adhesive force, but peels off in a long period of time when warp stress occurs in the floor material. Therefore, a nailing method can be considered. However, when a nail is used, the impact applied to the floor is transmitted to the floor base through the nail, so that the sound insulation of the foam is impaired at the portion where the nail is present.

In order to solve the above-mentioned problem, the present inventor firstly suggested that a cushioning member and a wooden board disposed on the cushioning member and provided with a horizontal protrusion and an adjacent wooden board protrusion accommodating notch at the bottom respectively. After the nailing, we proposed a wooden flooring in which the horizontal protrusions are deformed downwards and a space is created between the nail head and the adjacent wooden board above it.
29434).

However, as can be seen from FIG. 11 showing the above-mentioned proposed wooden flooring material, the horizontal protruding portion (2) indicated by a chain line reaches the floor base (8) through the cushioning member (1) from above. By hitting (5), the base end (2b) may be inclined obliquely downward. In this case, there is a concern that a step may occur between the wood board (4) and the adjacent wood board, or the adjacent wood board may rattle. Furthermore, the wood board (4) has a horizontal protrusion (2).
And to facilitate the provision of the adjacent wood board projecting part accommodating notch (3),
When these are joined to the upper plate (4a) and the lower plate (4b) separately, since stress concentrates on the base end (2b), the upper plate (4a) and the lower plate ( 4b) is easy to peel off. Of course, there is a problem of steps and rattling as in the above case.

An object of the present invention is to provide a wood flooring material that improves on the above problems.

Means for Solving the Problems In order to achieve the above-mentioned object, a wood flooring according to the present invention is provided with a cushioning member, a horizontal projection for nailing at the bottom of the cushioning member, and an adjacent wood board protrusion. It is made of a wood board each having a housing notch, and a number of discontinuous portions are provided at predetermined intervals in the length direction of the protrusion between the nailing zone of the horizontal protrusion and the base end of the protrusion. After the nailing, the horizontal projection outside the discontinuity is deformed downward after the discontinuity, and a space is created between the nail head and the adjacent wood board existing thereabove. Is.

Examples of the material of the cushioning member include foamed synthetic resin, foamed synthetic rubber, and fibrous material. Among them, the foamed synthetic resin is generally used. Specific examples of the synthetic resin include polyethylene, polypropylene, polyvinyl chloride, and polystyrene. ,
Polyurethane and phenol can be mentioned. Further, specific examples of the fibrous substance include insulation board, glass fiber, asbestos, a product obtained by impregnating these fibers with asphalt / pitch for waterproofing, felt, carpet and the like. The material of the buffer member is appropriately selected according to the performance required for the floor, and may be used alone or in combination.

As a concrete example of the wood board, plywood is generally used, but other sawn boards, laminated wood, particle board, hard board,
A medium specific gravity fiber board can be used, and its surface is appropriately coated with makeup. This makeup is usually performed by sticking a nameplate veneer, a pattern sheet, a synthetic resin sheet, cork or the like on the surface or applying a coating. However, there are cases where makeup is not applied.

The wooden board is usually rectangular, and its four sides are subjected to processing such as inversion, tongue-and-groove and other known joining methods.

The horizontal projecting portion and the adjacent wood board projecting portion accommodating notch may be formed into one wood board, but is formed by joining another board (lower board) to one board (upper board). Is more productive. The lower plate is also usually a wooden plate, but in some cases, a synthetic resin plate or a metal plate may be used. The size of the upper plate is arbitrary, but the length is 900-1800mm and the width is 100
~ 300mm, thickness is usually 5.0 ~ 15.0mm, the length and width of the lower plate is matched to the upper plate, when using plywood, the thickness is 1.5 ~ 6.0mm especially 2.0-
2.5 mm is preferred. Also, the protruding length of the horizontal protruding portion is of course determined by the relationship with the size of the upper plate, but is 20 to 70 mm.
It may be about 30 mm to 50 mm.

The shape of the discontinuous portion provided in the horizontal protruding portion may be a hole or a slit and may be arbitrary, but a round hole is easy to process.
Further, the discontinuous portion may be provided not only between the nailing zone of the horizontal projecting portion and the base end of the projecting portion but also between the nailing zone and the tip of the projecting portion, and in order to improve sound insulation, When the wooden board is composed of two upper and lower boards, a porous board may be used as the lower board.

The cushioning member may be previously joined and integrated with the lower surface of the wooden board, but it may be a separate body. The thickness of the cushioning member is appropriately determined in relation to the material thereof, the type of floor base material, and the like.

The floor base is usually a concrete floor, but it may be formed of an appropriate material such as plywood, particle board, or medium specific gravity fiber board.

It is preferable that the nail is as large as possible so that the driven head can be surely left on the horizontal protruding portion. For example, a nail having a diameter of about 10 mm is used. If the floor base is concrete, it is difficult for the nails to come into contact, so it is better to use a plug nail that drills a hole in the concrete surface, inserts a plug into this, and then drives the nail into the plug.

After nailing, the horizontal protrusion is deformed downward at the discontinuity so that a space is created between the nail head and the adjacent wood board above it. Is selected and the protrusion length and thickness of the horizontal protrusion are appropriately determined. Furthermore, the cross-sectional shape and layer form of the cushioning member below the horizontal protrusion may be such that the above space can be easily obtained. The distance between the nail head and the adjacent wood board existing on it in the obtained space may be about 0.2 to 5.0 mm,
Particularly, 1.5 to 3.0 mm is desirable.

The cushioning member and the wooden board disposed on the cushioning member are usually adhered to each other and integrated, but the two need not necessarily be adhered. In this case, a large-area cushioning member is laid on the floor substrate, and a wooden board is placed on the cushioning member and fixed with nails. Thus, when used as a cushioning member having a large area, a groove is formed in the upper portion of the cushioning member to accommodate a liquid-containing pipe having elasticity, and the liquid is cooled or heated to be used as a floor material for cooling and heating. Is also possible. Further, in order to obtain a flooring material for heating, a sheet-like heating element may be incorporated in the cushioning member.

In addition, in order to more securely fix the floor material to the floor base, the nailing method and the bonding method may be used in combination,
In some cases, an adhesive may be applied to the upper surface of the horizontal protruding portion of the wooden board, and the adhesive may be adhered to the upper surface of the notch portion for accommodating the protruding portion of the adjacent wooden board to completely prevent rattling of the adjacent wooden board.

Effect According to the wood floor material of the present invention, after nailing, the horizontal protrusion provided at the bottom of the wood board is deformed downward, and a space is created between the nail head and the adjacent wood board existing thereabove. Therefore, the impact applied to the floor is not transmitted to the floor base through the nail, and the sound insulation of the cushioning member in the portion where the nail is present is not impaired. Further, when a nail is struck in the horizontal protruding portion, the portion is bent from the place where the discontinuous portion exists, so that the vicinity of the base end of the protruding portion is kept horizontal.

Embodiment An embodiment of the present invention is shown in FIGS. 1 and 2. The wooden floor material shown in the figure is a buffer member (1) that is brought into contact with the floor base (8), and a horizontal nailing surface that is placed on the buffer member (1) and is joined to it and intersects the bottom at right angles. Protrusion
(2) is made up of rectangular wooden boards (4) each provided with adjacent wooden board projecting portion accommodating cutouts (3) on the remaining two sides intersecting at right angles.

Between the nailing zone (2a) of the horizontal protrusion (2) and the base end (2b) of the protrusion, a discontinuous portion (7) consisting of a large number of round holes is formed in the length direction of the protrusion (2). It is provided at predetermined intervals. In the figure, the discontinuous part (7) consisting of a round hole is the nailing zone (2a) and the base end (2) of the protruding part.
Although it is located almost in the center of b), it may be located near the base end (2b) of the protrusion. And after nailing, the discontinuity
The outer horizontal projection (2) is deformed downward at the boundary of (7), and a space (6) is created between the nail head (5a) and the adjacent wood board (4) existing thereabove. It is done like this.

The wood board (4) is made of plywood and is divided into an upper board (4a) and a lower board (4b) so that the horizontal projection (2) and the adjacent wood board projection accommodating notch (3) can be easily provided. These are joined together, and the thickness of the lower plate (4b) is the same as that of the nailing portion (2).

Example 2 This example is that shown in FIGS. 3 and 4. In the floor material of the same figure, the horizontal projection (2) has a discontinuous portion (7) consisting of a round hole, between the nailing zone (2a) and the projection base end (2b), and the nailing zone ( It is provided between 2a) and the tip of the protrusion (2c). Others are the same as in the first embodiment.

5 to 8 show modification examples of the shape of the discontinuous portion.

Fig. 5 shows that the discontinuity (17) is a triangular hole, and its vertices are alternately reversed, and Fig. 6 shows that the discontinuity (27) consists of slits. Indicates that the discontinuous portion (37) is composed of an elongated rectangular hole. These discontinuities
(17), (27) and (37) are all nailing zones (2
Between the a) and the base of the protrusion (2b), they are provided at predetermined intervals in the length direction of the protrusion (2). Figure 8 shows the horizontal protrusion
In (2), the discontinuous part (7) consisting of a square hole is formed between the nailing zone (2a) and the base end (2b) of the protrusion, and the nailing zone (2a) and the tip of the protrusion.
The one provided between (2c) is shown.

Example 3 This example is the one shown in FIG. The floor material of the same figure, the cushioning member (1) upper layer (1c) located below the horizontal protrusion (2) and the upper layer (1a) at other positions, and both upper layers (1a) (1c) Upper layer consisting of the lower layer (1b) below
For (1c), a material that is relatively softer than the latter upper layer (1a) and lower layer (1b) is used. The cushioning member (1) is integrally joined to the wood board (4). In this embodiment, the latter upper layer (1a) and lower layer (1b) may not be divided and both may be integrated. Others are the same as those in the first embodiment.

Example 4 This example is shown in FIG. 10, in which the upper layer (1c) under the horizontal protrusion (2) in Example 3 was omitted, so that the step (9 ) Has been formed. The horizontal protrusion (2) therefore inevitably bends and abuts the upper surface of the lower layer (1b) when the nail (5) is driven in. A space (6) larger than those in Examples 1 to 3 is provided thereabove.
Is obtained.

Also in this embodiment, without dividing into the upper layer (1a) and the lower layer (1b),
As in the third embodiment, both may be integrated.

According to the wood floor material of the present invention, since there is a cushioning member under the wood board, the sound insulation is good, and further, after nailing, the horizontal protruding portion provided at the bottom of the wood board is deformed downward, and Since a space is created between the wooden board and the adjacent wooden board existing thereabove, the impact applied to the floor is not transmitted to the floor base through the nail, and the sound insulation of the cushioning member in the portion where the nail is present is not impaired. Therefore, it is possible to use a nailing method that has better workability than the adhesive construction method, and since the floor material can be fixed to the floor base with nails, the floor material can be much better than the adhesively fixed one when renovating the floor. Easy to remove from floor base.

Further, since a number of discontinuities are provided at predetermined intervals in the length direction of the protrusion between the nailing zone of the horizontal protrusion and the base end of the protrusion, when nailing the horizontal protrusion. , It bends from the place where there is a discontinuity, and the vicinity of the base end of the protrusion is kept horizontal. Therefore, there is no concern that a step will occur between the nailed wooden board and the adjacent wooden board, or the adjacent wooden board will rattle, and the wooden board is divided into an upper board and a lower board and these are joined. Even if it is twisted, there is no fear that the upper plate and the lower plate will be separated from the base end of the protrusion.
