Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor board, particularly a floor board suitable for being directly attached to a concrete floor surface and having a soundproof property.

[0002]

[Prior art]

 In Japanese Utility Model Publication No. 3-31781, a plurality of elongated decorative plates each having a joining means on a side surface, an appropriate number of concave grooves are formed in a lateral direction of the surface, and a cut is made from the back surface in the vicinity of the concave grooves. , A makeup made by arranging them in a row in the short direction so that the grooves are not aligned and are aligned in the short direction, and a flexible base material with a cushioning property is attached over almost the entire back surface. Plates are known. This decorative board is used as a floor board that is directly attached to the concrete floor surface.

[0003]

[Problems to be solved by the device]

 In this conventional decorative plate, the elongated decorative plates are not adhesively bonded to each other, but are simply adhered and supported on the flexible base material on the back surface. In addition, it has an advantage that the conformability to the unevenness of the concrete floor surface is excellently exhibited even in the longitudinal direction.

However, since the back surface is a cushioning flexible base material, each elongated decorative board itself independently responds to the load from the front surface, especially in the short-side direction. In the joined joints, an unreasonable force is applied to both joining means, which is liable to cause actual damage.

In addition, since each elongated decorative plate is provided with a concave groove from the front surface side and a notch from the rear surface side at a position close to each other, it has good flexibility but lacks strength. There was a drawback that the decorative board itself was easily broken in some parts.

[0006]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problems of the prior art, and shows good conformability to the unevenness of the concrete floor surface to be directly pasted in both the longitudinal direction and the lateral direction, but from the surface. It is an object of the present invention to provide a floorboard that can prevent fruit from being damaged when it receives a load.

That is, in the floorboard according to the present invention, a plurality of rectangular floor bases are connected in the longitudinal direction through the fitting means formed at the four-circle opening and have a dimension longer than the width of the floor base. It is characterized in that it is shifted and connected in the longitudinal direction to form a wide floor base material, and each floor base material is integrally attached to the back plate on the back surface of this wide floor base connection body. It

As the floor base material, solid wood, plywood, wood fiber board, particle board, composite materials of these, and the like are appropriately used.

On the surface of the floor base material, makeup is applied by an arbitrary method such as color coating, pattern printing, sticking of a sheet material such as a veneer, decorative paper or a synthetic resin sheet for makeup. Furthermore, a transparent coating can be applied on the decorative surface. Also, chamfering may be applied to the four peripheral edges of the floor base material surface.

A fitting means formed by actual machining, phase-determination machining, or the like is formed at the four-edge opening of the floor base material.

It is possible to engrave a plurality of grooves on the back surface of each floor base material, which acts as a sound absorbing chamber that absorbs the vibration energy generated and propagated by the impact applied to the front surface, and the sound insulation of the floor board. Improve. In the present invention, since the concave groove is not formed on the surface of the floor base material, there is no problem of lowering the strength due to the groove on the front surface and the groove on the rear surface being formed close to each other.

Generally, the groove on the back surface is formed so as to extend in the lateral direction, but it may be extended in the longitudinal direction or the diagonal direction, and for example, in the lateral direction and the longitudinal direction. It may be crossed and extended. Further, instead of the groove, a hole having an arbitrary cross-sectional shape may be used.

The depth, width, cross-sectional area, quantity, etc. of the grooves or holes formed on the back surface are appropriately selected and determined according to the soundproof performance to be obtained.

An arbitrary number of floor base materials are connected in the longitudinal direction to obtain a long-sized floor base material connected body, and then an arbitrary number of the long floor base material connected bodies are connected in the short-side direction to form a wide floor base material. A base material continuous body is obtained. At the time of connecting them, adhesive tape, gum tape, etc. are used to temporarily fix the floor base materials to the connected state.

In the floor board of the present invention, when connecting the long-sized floor base material connecting body in the lateral direction, it is essential to shift the lengthwise direction by a dimension longer than the width dimension of the floor base material. In other words, if this offset size becomes smaller, the length of fitting between the floor base material of another floor plate that is installed adjacently becomes smaller, and it becomes difficult to provide the fitting means with sufficient supporting strength. However, when a heavy object is placed only on the floor base material of one of the floor plates, the male fruit forming the fitting means may be damaged.

In addition, since the floorboard according to the present invention is largely flexed in the lateral direction through the fitting means that extends continuously in the longitudinal direction, the floor substrate has a longitudinally displaced dimension. If it is small, there is a risk that other floor boards that will be installed adjacent to the floor base material will be out of fit.

From the above, it is necessary to make the lengthwise shift dimension of the floor base material larger than its width dimension, but even if it is made larger than 1/2 of the total length of the long floor base material continuous body, Since it is meaningless that the shift dimension on the opposite side becomes short, it should be 1/2 or less of the total length. From the viewpoint of designability, it is preferable that the length of the continuous long-sized floor substrate connected body be ⅓ or less, and the above-mentioned effects can be sufficiently exhibited.

An adhesive is applied to the back surface and / or the surface of the back plate of the obtained wide floor base material connecting body, and the wide floor base material connecting body is laminated on the back plate and pressure-bonded. Finally, the temporary fixing tape used for connection is removed to obtain the floorboard of the present invention.

Alternatively, the floor base material is sequentially connected directly to the back plate coated with the adhesive through the fitting means, and after the predetermined arrangement is obtained, the floor base materials are laminated and pressure-bonded to each other. May be.

For the back plate, plywood, wood fiber board, particle board, composite material of these, or the like is appropriately used. In order to secure the flexibility of the floor board, it is required that the rigidity is relatively low and the flexible material is easily bent, and the thickness is preferably 6 mm or less.

By further adhering a soundproofing sheet to the back surface of the back plate, the soundproofing performance can be further improved. Soundproofing sheets include rubber-based, synthetic resin-based, foamed rubber-based, foaming synthetic resin-based sheets, sheets in which organic or inorganic powders or fibrous substances are mixed, non-woven fabrics, cardboard, coconut shell fibers. Fiber sheets made of cellulose fibers, synthetic fibers, or the like may be used. Also, any combination of these sheet-like materials may be used, for example, one in which a plurality of foamed synthetic resin sheets having different expansion ratios are laminated, one in which a foamed synthetic resin sheet and a non-woven fabric are laminated, and the like. It may be a soundproof sheet.

[Action]

 Since the floor base material is a floor board that is fitted and connected to the back plate surface with low rigidity in the longitudinal direction and the short-side direction of the floor base material without being bonded and fixed by the fitting means, the floor base material is directly attached to the floor surface. When applied, it shows good flexibility in both the longitudinal and lateral directions and fits well on uneven floors.

When connecting the floor base material in the lateral direction, the floor base material is displaced in the longitudinal direction by a distance larger than the width dimension of the floor base material. Corrugation damage is prevented.
