DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a long floor material used for constructing a floor of a large room or a corridor.

[0002]

2. Description of the Related Art Conventional floor materials also have a longer side longer than a shorter side, but the length in the longitudinal direction is usually six feet. For this reason, when a large-sized room or corridor is constructed, a vertical joint is always formed and the design is poor. Further, even if an attempt was made to form a long floor material having a length in the longitudinal direction of 6 or more, there was no plate material such as plywood generally supplied to the market that was 6 or more, and a long floor material could not be manufactured. .

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to improve the design of a large-sized room or corridor without connecting it vertically. To provide a long floor material that can be used.

[0004]

In order to achieve the above object, the long floor material A according to the present invention is a long long floor material whose long side is much longer than its short side. One decorative veneer 2 is connected to the upper surface of the substrate 1 in the longitudinal direction at least at one location in the longitudinal direction, and the connecting portion of the substrate 1
The reinforcing member 3 is attached to the lower surface side of the
The reinforcing backing material 4 is attached so as to cover the entire surface .

[0005]

[0006]

According to the above construction, since the base material 1 is connected at least at one position in the longitudinal direction, a long base material 1 can be formed using a commercially available plate material. 1
Even if they are connected, the decorative veneer 2 has the appearance of a single product. Therefore, it is possible to construct a large room or corridor without vertical connection, and the design can be improved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A long floor material A is formed by attaching a decorative veneer 2 to the upper surface of a base material 1 such as plywood, and has a long side much longer than a short side. Specifically, the length of the long floor material A in the longitudinal direction is formed to be 12 in accordance with the dimension between two rooms. A commercially available plywood is used as the base material 1 and is connected to at least one or more places at appropriate places in the longitudinal direction. This connecting portion is connected by a scarf joint, for example, as shown in FIG. 1B, and the slope portions 5 at the ends are connected to each other. One decorative veneer 2 is adhered to the upper surface of the base material 1 in the longitudinal direction with an adhesive. The surface of the decorative veneer 2 is sanded and colored as required. Connection of substrate 1
The reinforcing member 3 is buried on the back side of the portion to reinforce it.
The backing material 4 for reinforcement is stuck on the back side of the material 1 over the entire surface.
is there. The reinforcing backing material 4 is made of, for example, softwood or hardwood.
It is a thin veneer. Female members 6 and male members 7 are provided on both sides in the short side direction of the long floor material A so as to extend in the longitudinal direction.
Specifically, this long floor material A has two length directions (1
The end face of the end in the longitudinal direction is not actually processed because it is used exclusively for a room or a hallway of 2 feet. The long floor material A constructed as described above is stuck on the floor side by side, but when a room of 16 tatami or less (length direction is 12 feet) is constructed, there is no seam in the longitudinal direction, and there is no gap or unevenness. There is no problem, there is a sense of quality and the design can be enhanced.

[0008]

In the case of using a cross plywood as the base material 1 and forming a long floor material A having crack resistance, the following procedure is performed. The fiber direction of the face of the cross plywood is arranged so as to cross the longitudinal direction of the base material 1, and the cross plywood is connected by a scarf joint to form the base material 1 made of a long cross plywood. The decorative veneer 2 is adhered to the upper surface of the substrate 1 with an adhesive such that the fiber direction of the decorative veneer 2 is parallel to the longitudinal direction of the substrate 1. This decorative veneer 2
A raw (wet) veneer having a thickness of 0.2 to 0.35 mm or a dry veneer having a thickness of 0.4 to 0.6 mm is used.
After the decorative veneer 2 is applied, the surface of the decorative veneer 2 is sanded, colored and painted, and the actual processing is performed on both sides in the longitudinal direction. The long floor material A thus formed has good crack resistance.

[0010]

FIG . 2 shows another embodiment. In the case of the present embodiment, after the decorative veneer 2 is adhered to the upper surface of the base material 1, the decorative veneer 2
Is sanded, and a colored coating (undercoat and intermediate coat) is applied thereon. Next, a top coat (finish) coating is performed. When the top coat is in a contact dry state (only the surface of the coating film is dried), the top coating is passed through a mesh roll 10 having an irregular mesh processing on the surface, so that the coating is completed. The film is provided with an uneven mesh 11 and dried. By doing so, a long floor material A that is less slippery when walking can be obtained.

[0012]

As described above, according to the present invention, by connecting the base material at at least one position in the longitudinal direction, a long base material can be formed using a commercially available plate material. Even if the materials are connected, the decorative veneer has the appearance of a single sheet, and a long floor material having a long length in the longitudinal direction can be easily obtained. Therefore, by using long floor materials, construction can be performed without any vertical joints even in large rooms and corridors, there is no problem of gaps and steps, and there is a sense of quality and high design quality Can be done. In addition, a reinforcing part is provided on the lower side of the connection part of the base material.
Since the material has been attached, the lower surface side of the connection part of the base material is supplemented.
It can be connected firmly and securely, and the lower surface of the substrate
As the backing material for reinforcement was pasted on the side all over,
The entire lower surface of the substrate can be reinforced with a backing material for reinforcement
Therefore, even those that connect the base material have sufficient strength.
It can be reinforced.
