[0013]

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.

[0014] In the present specification, the term "groove type plate" refers to a plate having a structure in which the longitudinal side surfaces can be connected with the shape of a rib for joining the plates. 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.

In the present specification, a tongue-and-groove type joint means that when connecting a plate material in the width direction, a projecting portion on one side in the longitudinal direction, which is a joining 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. If there is no projection piece 2, when the plate material is joined, it is accommodated in a portion where the projection can be accommodated, and the projection surface side butting surface 101 and the concave surface side butting surface 106 are provided.
The convex part front 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 110
Are matched against each other.

However, in the plate material according to the present invention, the butting surface 110 of the adjacent plate material comes into contact with the projection piece 2. Therefore, the abutting surfaces are separated from each other by a distance between the protruding piece 2 and the convex back side abutting surface 105. There is a joint. For this reason, FIG.
As described above, even if a spacer is not used at the time of construction, a constant distance is always obtained between the plate materials, and an excellent effect that construction is extremely easy can be obtained.

[0017] In the present specification, the joining of a pair of jig-and-groove type refers to joining two plate materials by cutting off a joint part of the two plate materials by half of the plate thickness when connecting the plate materials in the width direction. That is, it refers to the 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 joint portion of the joint type with a tongue and groove 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 301, the back facing overlapping surface 302, and the back side abutting surface 303 are respectively referred to in order from the front side. Further, on the side where the opposite front side is cut off (that is, the side where the accommodating portion is located), the front side butting surface 304, the front overlapping surface 305, and the back side front butting surface 3 are arranged in this order from the front side.
06. In this case, as in the case of the real tongue-and-groove type, when there is no projection piece 4, the respective butting surfaces are directly butted.

However, since the plate member of the present invention has the projection piece 4, the projection piece 4 comes into contact with the rear end side abutting surface 306 of the adjacent plate material. Therefore, the projecting piece 4 and the back side abutting surface 3
03 and the joint is formed on the surface 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 protrusion 2 or 4 is
In order to form joints at regular intervals on the front surface side, protrusions are provided on the back facing overlapping surface 104 or 302 of the joint portion, respectively, and are lower than the height of the back side abutting surface 105 or 303 and have an appropriate thickness. Say. The elastic modulus of the material forming these projection pieces is lower than the elastic modulus of the material forming the main body of the plate material. Therefore, the protrusion 2 or 4
Is easily bent 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 in this manner, it becomes possible to absorb (or buffer) the strain between the swollen plates and prevent the plate material from floating from the construction surface.

Further, 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 a constant interval can be held. It may be intermittently present as a plurality of arranged projection pieces.

In the plate material of the present invention, the distance between the tip end 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.

The surface of the sheet material main body according to the present invention may have a groove for fixing a tucker or a groove for injecting an adhesive for fixing the sheet material to the work 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 used as the main body of the plate of the present invention is not particularly limited, and 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 is, for example, pine,
Wood powder produced by pulverizing waste wood, sawdust and the like generated in the process of lumbering natural trees such as cedar, cypress and hemlock 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 is 10 to 70
%, Preferably 20 to 50% by weight.

The resin in the wood powder-containing resin may be either a thermosetting resin or a thermoplastic resin, but is preferably a thermoplastic resin. Most preferably, an ABS resin is used. Especially when using ABS resin,
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, antibacterial agents, bactericides, anti-algae agents, anti-fading agents, 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.

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.

The material of the projecting piece of the plate of the present invention is not particularly limited as long as the elastic modulus of the material forming the projecting piece is lower than the elastic modulus of the material forming the main body of the plate, but is preferably an elastomer. Is preferred. This is because if the projection is made of an elastomer having elasticity, it can easily bend and absorb the expansion of the plate material body when a load is applied from the abutting surface. The elastomer used for the projection of the plate material of the present invention is more preferably a thermoplastic elastomer. In particular, styrene-based TPE (SBC), olefin-based TPE (T
PO), vinyl chloride-based TPE (TPVC), urethane-based TPE (TP
U), polyester TPE (TPEE), and amide TPE
(TPAE) is preferred.

The above-mentioned projecting piece may be manufactured by any method depending on the material. In the case of an elastomer, it is generally manufactured by extrusion.

The method of bonding the projection pieces to the plate material body of the present invention is not particularly limited, and may be bonded by a method commonly used by those skilled in the art, for example, by using an adhesive or by melting. If the plate material body is made of resin or wood flour-containing resin, and the projection pieces are made of an elastomer, the plate material body and the projection pieces are manufactured in a bonded form by simultaneously extruding and extruding two pieces. Preferably.

[0035]

EXAMPLE A tongue-and-groove type plate member having a cross section shown in FIG. 3 was prepared by co-extrusion of a wood powder-containing ABS resin and a thermoplastic TPEE elastomer. As shown in FIG. 3, the plate members were joined so that the concave back surface side butting surface 110 and the projecting piece 2 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 2. As a result, joints at regular intervals were formed on the surface without using spacers. Since the protruding piece 2 is on the back side, the space between the joints is only slightly reduced from the front side, and the appearance is not affected.

[0036]

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.
