DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material which can be installed while maintaining joints at a constant interval.

[0002]

2. Description of the Related Art In general, plate members are joined in the width direction by a real tongue or a claw. For example, when a waistboard is constructed, a decorative joint is often provided for a design purpose, and for this purpose, the joint portions must be overlapped while being shifted by the joint size. In order to provide joints at regular intervals, for example, as shown in FIG. 4, it is necessary to work with spacers 4 interposed between joints between plate members 3. Therefore, the construction work was difficult and time-consuming.

[0003] On the other hand, by providing joints, when the plate material expands and contracts due to a temperature change after construction or swells due to moisture, it is possible to prevent the plate materials from colliding with each other at a joint portion and rising from the construction surface, A flat surface is maintained. In this way, the joints are designed,
It is also important in maintaining the joining of the plate materials. Therefore,
It is necessary to provide joints at regular intervals.

[0004]

Therefore, there is a need for a method that can maintain joints at regular intervals and that can be easily constructed.

[0005]

SUMMARY OF THE INVENTION The present invention provides a plate material which can be constructed while maintaining joints at regular intervals.

That is, the present invention provides a main body having a projection provided on one side surface in the longitudinal direction, and a portion provided on the other side surface in the longitudinal direction and capable of accommodating the projection;
When the protrusion of another plate material is accommodated in the accommodable portion, the main body is provided on the back-facing surface of the protrusion of the main body so as to form joints at regular intervals on the surface side of the main body. And a projection provided along the longitudinal direction of the plate.

In a preferred embodiment, the projecting pieces are continuous projecting pieces.

[0008] In a preferred embodiment, the protruding piece comprises a plurality of protruding pieces arranged along the longitudinal direction of the main body.

[0009] In a preferred embodiment, the plate is a tongue-and-groove type plate.

[0010] In a preferred embodiment, the plate material is a phased-and-groove type plate material.

[0011] In a preferred embodiment, the board is made of wood powder-containing resin, resin, plywood, or metal.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention can be applied to the joining of any of a real tongue-and-groove type plate material.
Provided is a plate member capable of easily forming joints at regular intervals.

[0013] In the present specification, the term “groove type board” refers to a board having a structure in which the longitudinal side surfaces can be joined with a real groove type in order to join the boards. In addition, the plate material of the joint jigging type is a plate material having a structure such that the side surfaces in the longitudinal direction can be joined by the joint jig type to join the plate members.

[0014] In the present specification, a tongue-and-groove type joint means that when connecting plate members in the width direction, a projecting portion on one side in the longitudinal direction, which is a joint portion, is convex, and a housingable portion on the other side. Refers to the joining of plate materials in which a plate material is concave. In the present specification, the names of the respective surfaces of the bonding portion of the tongue-and-groove type are defined as follows with reference to FIG. 1 which is a cross-sectional view: In FIG. In the convex portion, in order from the front surface side, a convex surface front side abutting surface 101, a front overlapping surface 102, a convex front end abutting surface 103, a rear facing overlapping surface 104, and a convex rear surface side abutting surface 105 are provided. . In the concave portion, the concave surface side butting surface 10
6, concave facing surface 107, concave butting surface 10
8, a concave surface facing overlapping surface 109 and a concave back surface side butting surface 110. When there is no projection piece 12, when the plate material is joined, it is accommodated in a portion where the projection can be accommodated,
The convex surface front side butting surface 101 and the concave surface front side butting surface 10
6. The convex part front end butting surface 103 and the concave part butting surface 108, and the convex part back side butting surface 105 and the concave part back side butting surface 1
10 are respectively matched.

However, in the plate material according to the present invention, the abutting surface 110 of the concave back surface of the adjacent plate material comes into contact with the protruding piece 12. Therefore, the abutting surfaces are separated from each other by a distance between the protruding piece 12 and the protruding back side abutting surface 105, and between the protruding surface front abutting surface 101 and the concave surface front abutting surface 106.
Joints at this interval are created. For this reason, even if it does not use a spacer at the time of construction like FIG. 4 which shows the conventional method, the fixed space | interval is always obtained between board materials, and the outstanding effect that construction becomes very easy is acquired.

[0016] In the present specification, the joining of a pair of jig-and-groove type means that, when connecting the plate members in the width direction, the joint portion of the two plate members is cut off by half of the plate thickness to join the plate members. In other words, it refers to joining of plate materials in which a protruding portion on one side surface in the longitudinal direction, which is a joining portion, is combined with a plate material having an accommodating portion on the other side surface on the surface side. In the present specification, the names of the respective surfaces of the joints of the joint type with a tongue and groove type are defined as follows with reference to FIG. 2 which is a cross-sectional view: FIG. Side and
The side where the back side is cut off (that is, the side with the protrusion)
In this case, the front side abutting surface 201, the back-facing overlapping surface 202, and the back side abutting surface 203 are respectively referred to from the front side. On the other side where the front surface side is cut off (that is, the side where the accommodable portion is present), the front side butting surface 204, the front overlapping surface 205, and the back side front butting surface 2 are arranged in this order from the front side.
06. Also in this case, as in the case of the real tongue-and-groove type, when there is no projection piece 22, the butting surfaces are directly butted.

However, since the plate member of the present invention has the protruding piece 22, the protruding piece 22 and the back end side abutting surface 20 of the adjacent plate material are provided.
6 contacts. Accordingly, the projection piece 22 and the back side abutting surface 203 are separated from each other by a distance, and joints are formed on the front side. In this way, even in the case of the double-faced tongue-and-groove type, as in the case of the above-mentioned real tongue-and-groove type, a constant interval is always obtained between the plate materials without using a spacer at the time of construction, and the construction is extremely easy. Is obtained.

In the present specification, the projecting pieces 12 or 22
Are provided on the back-facing overlapping surfaces 104 or 202 of the joining portions, respectively, to form joints at regular intervals on the front surface side, and are lower than the height of the back-side abutting surfaces 105 or 203, and have an appropriate thickness. Refers to a protrusion. Preferably, the protruding pieces 12 or 22 are formed to have a structure that easily bends or bends when a load is applied from the tip side of the protruding portion in a direction parallel to the face-down overlapping surface. By bending or bending, it becomes possible to absorb (or buffer) the strain between the swollen plates and prevent the plate material from floating from the construction surface.

The projecting piece may be present as a projecting piece that is continuous with the face-to-face overlapping surface, or along a longitudinal direction of the main body if joints at predetermined intervals can be held. It may be present intermittently as a plurality of arranged projections.

In the plate material of the present invention, the interval between the tip of the projection piece and the back side abutting surface is the same as the width of the predetermined joint. In the plate material of the present invention, the joints are provided in consideration of expansion and contraction of the material so as not to cause distortion after construction. For example, in the case of a board made of wood powder-containing resin containing wood powder in a completely dried state, since it swells after construction, it is necessary to provide joints so that adjacent board materials directly abut each other on the construction surface and rise from the construction surface. Can be avoided. Further, when constructed as a waistboard or the like, it also serves as a cosmetic joint.

On the surface of the plate material of the present invention,
There may be a groove for fixing a tucker or a groove for injecting an adhesive for fixing the plate material to the construction surface. Further, a groove for injecting an adhesive or the like may be provided on the back surface of the plate material body.

The material of the plate of the present invention is not particularly limited.
For example, wood powder-containing resin, resin, natural wood, metal and the like are used. Preferably, a wood powder-containing resin is used.

The wood flour in the wood flour-containing resin used in the board of the present invention is obtained by pulverizing waste wood, sawdust and the like generated in the process of sawing natural wood such as pine, cedar, cypress and hemlock. Wood flour is used. These are used alone or in combination.

These wood flours are dry wood flours, and preferably, wood flour in an absolutely dry state is used.

The amount of wood flour in the wood flour-containing resin used in the board of the present invention is 10 to 70% by weight, preferably 2 to 70% by weight.
0 to 50% by weight.

The resin in the wood powder-containing resin used for the board of the present invention may be either a thermosetting resin or a thermoplastic resin, but is preferably a thermoplastic resin.
Most preferably, an ABS resin is used. Especially ABS
When a resin is used, the strength is improved, the woodiness of the surface of the plate is high, the edges of the plate can be sharply formed, and fine extrusion can be performed. These thermoplastic resins may be used alone or in combination of two or more.

The wood flour-containing resin may contain various additives (for example, an antibacterial agent, a bactericide, an anti-algae agent, an anti-fading agent) which are commonly used by those skilled in the art within a range not affecting the effects of the present invention. Flame retardants, etc.).

As the natural wood, for example, pine, cedar, cypress, hemlock, karin, ash, elm, sakura, zelkova, etc. are used, but since they are expensive, they are generally used as plywood.

As the metal, steel, aluminum,
Copper or the like is used. In the case of a metal, for example, pultruding or press molding is performed. In the case of metal, it is preferable that the protruding pieces 12 or 22 be formed in a thin and easily breakable structure.

As the resin, either a thermosetting resin or a thermoplastic resin may be used, and a thermoplastic resin is particularly preferable. In the case of a thermoplastic resin, it is generally extruded.

[0031]

EXAMPLE A plate of the shape of a tongue-and-groove having the cross section shown in FIG. 3 was produced by extruding an ABS resin containing wood flour. As shown in FIG. 3, the plate members were joined so that the concave back surface side butting surface 110 and the projecting piece 12 were in contact with each other. As described above, when the plate members were joined, each plate member was joined with a gap between the projection back surface side abutting surface 105 and the tip of the projection piece 12. As a result, joints at regular intervals were formed on the surface without using a spacer. Since the protruding pieces 12 were on the back side, the joints were seen only slightly narrower from the front side, and did not affect the appearance.

[0032]

By using the plate material of the present invention, it is possible to join the plate material to the construction surface while maintaining joints at regular intervals without performing a complicated operation such as using a spacer. Therefore, the board of the present invention is suitable for use as a floorboard, a waistboard and the like.
