Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a decorative flooring material that is directly attached to a concrete floor or is applied to a floor base such as joists, plywood, and particle board.

2. Description of the Related Art Conventionally, a rectangular random scale decorative flooring material is known as a decorative flooring material.

Problems to be Solved by the Invention As shown in FIG. 9, when a large number of conventional decorative flooring materials (B) are closely adhered to the floor base, the short side surfaces of the decorative flooring materials (B) are A straight seam (21) was generated, and there was a feeling that a random scale pattern could not be obtained on the entire floor.

Of course, it is also possible to consider a construction method in which strips are used for the decorative flooring itself, and the flooring materials that are adjacent in the width direction are shifted in the lengthwise direction so that they are closely arranged so that a random pattern can be obtained over the entire floor surface. However, such a construction method is extremely inefficient and unrealistic.

The purpose of this invention is to obtain a random pattern on the entire floor without deteriorating the construction efficiency, there is no fear that the adhesive will stick out on the upper surface of the floor material when joining the decorative floor materials, and the edges of the decorative material during handling. It is to provide a decorative flooring that does not chip.

Means for Solving the Problems To achieve the above object, a decorative flooring material according to the present invention comprises a substrate and a decorative material composed of a plurality of parallel close strip-shaped decorative strips adhered onto the substrate. Both ends of the makeups that are adjacent to each other in the width direction are shifted in the lengthwise direction in a stepwise manner when seen from a plane, and one end of the substrate is formed to have substantially the same shape and size as the decorative material. The nailing part is formed by projecting the edge part from the decorative material, and the stepped part on the other end of the board and the other side edge part are retracted from the decorative material to form the nailing part insertion part of the adjacent floor material. , Furthermore, a staggered portion of the plurality of decorative pieces constituting the decorative material on at least one side of the stepped portions at both ends is formed with a cutout portion for the adhesive pool at the lower part of the side edge portion, and the staggered portions at both ends are misaligned. A joint is formed around the decorative material excluding the side edges. .

Plywood having a thickness of 2 to 9 mm is suitable as the substrate, but particle boards or medium specific gravity fiber boards having a thickness of 3 to 12 mm are also preferable, and other inorganic plates, synthetic resin plates or metal plates can also be used. A cushioning material such as synthetic resin foam may be adhered to the lower surface of the substrate.

The decorative pieces constituting the decorative material are obtained by pasting a decorative veneer with a thickness of 0.2 to 3.0 mm on a plywood plate with a thickness of 2.5 to 7.0 mm and vertically dividing this into a required number. However, a medium specific gravity fiber board can be used instead of the plywood.

A suitable width of the nailing portion is 20 to 70 mm.

Action When applying a large number of decorative flooring materials according to the present invention to the floor substrate in close contact, nails are driven into the nailing portion of the decorative flooring material so as to reach the floor substrate, and then adhesive is manually applied to the nailing portion. After that, the joint portions of the adjacent decorative floor materials are matched with each other, and the nailing portion insertion portion of the one decorative floor material is matched with the nail driving portion of the other decorative floor material. In this case, the staggered side edge portions of the decorative pieces of the adjacent decorative flooring materials are directly butted to each other, but in the notch portion at the bottom of the staggered side edge portion on at least one side of the stepped portions at both ends, The remaining adhesive on the upper surface of the nailing part
It is pressed against the lower surface of the decorative material at the insertion portion and flows into it, where it accumulates. Further, since both ends of the plurality of decorative pieces constituting the decorative material are displaced in a stepwise manner when viewed from the plane in the lengthwise direction, an irregular scale pattern is obtained on the entire floor. Moreover, the stepped portion and one side edge of the substrate formed to have substantially the same shape and size as the decorative material are made to protrude from the decorative material to form a nailing portion, and the other end of the substrate has a stepped portion and Since the nailing portion insertion portion of the adjacent floor material is formed by retracting the other side edge portion from the decorative material, the decorative material does not partially project extremely from the substrate.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In this specification, the left and right means the left and right of FIG. 1, and the front and back means the upper and lower parts of the figure.

The decorative flooring shown in FIGS. 1 and 2 is a substrate
(1) and a decorative material (3) consisting of a plurality of parallel close strip-shaped decorative pieces (2) adhered onto the substrate (1). Both ends of the decorative strips (2) adjacent to each other in the width direction are displaced in a stepwise manner when viewed from the plane in the longitudinal direction, and the substrate (1) is formed to have substantially the same shape and size as the decorative material (3). One end of the stepped portion (10) and one side edge are projected from the decorative material (3) to form a nailing portion (4), and the other end of the substrate (1) stepped portion (11) and the other side. An edge portion is retracted from the decorative material (3) to form a nailing portion insertion portion (5) of the adjacent floor material. At the lower part of the entire side edge portion including the staggered side edge portions (6) of the plurality of decorative pieces (2) constituting the decorative material (3), a notch for adhesive pool (7) is formed. Adjacent floor material around the decorative material (3) excluding the staggered side edges (6)
A joint part (8) consisting of a tenon corresponding to the joint form of (A),
A joint portion (9) formed of a small hole is formed.

The left end stepped portion (10) of the substrate (1) is formed to face forward and the right end stepped portion (11) is formed to face backward. This is a single rectangular plate for a substrate. At the center, if you cut it into two steps by cutting it in steps from the plane, and make the straight short sides (12) (13) sides of both halves (1A) (1B) face each other, it is shown in Fig. 1. A substrate (1) having a shape as described above is obtained.

It should be noted that there may be a gap between the two opposing straight short sides (12) and (13) as shown in the figure, or they may be in close contact with each other. You may use sweet potato joints when closely contacting.

3 and 4 show how to make a decorative piece (2) having a cutout (7) for accumulating an adhesive. First of all, as shown in FIG.
A joining part (8) consisting of a tenon is formed on each side, and a joining part (9) consisting of a small hole is formed on the other two orthogonal sides. Then, along the lengthwise line (15) that divides the width of the decorative rectangular plate (14) into three equal parts, a groove (16) whose cross section extends over both sides thereof is provided. Finally, the rectangular plate (14) is longitudinally divided along the line (15) to obtain three decorative pieces (2) as shown in FIG. At this time, the groove (16) is divided into two in the front and back to form the cutout portion (7) for accumulating the adhesive of each decorative piece (2).

When applying a large number of decorative floor materials (A) closely to the floor base, nails (20) are driven into the nailing part (4) of the decorative floor material (A) so as to reach the floor base (17), and then Manually apply adhesive to the nailing part (14) and then join the adjoining decorative flooring (A) (8) (9)
While fitting them together, insert the nailing part insertion part (5) of one decorative flooring (A) into the nailing part after nailing the other decorative flooring (A).
Match (4).

FIG. 5 shows that both ends of a plurality of decorative pieces (2) constituting the decorative material (3) are staggered in the lengthwise direction when viewed from the plane, so that a large number of decorative flooring materials (A) are closely attached. When arranged in a pattern, a random scale pattern is obtained on the entire floor.

Also, when a large number of decorative flooring materials (A) are closely arranged, the staggered side edges (6) of the adjacent decorative pieces (2) are butted against each other, but the staggered side edges (6) The remaining adhesive (18) on the upper surface of the nail striking part (4) is pressed against the lower surface of the decorative material (3) at the nail striking part insertion part (5) and flows into the notch part (7) at the bottom and flows. FIG. 6 shows the state in which the lumps are accumulated here. As shown in FIG. 8, the notch (27) may be formed only on one of the two staggered side edges (6) but the cross-sectional shape thereof is arbitrary. Is.

If the cutouts (7) and (27) are not present, as shown in FIG. 7, when the staggered side edges (6) of the adjacent decorative strips (2) are butted to each other, the protrusions are not formed. The adhesive (18) pressed by the fitting protrudes onto the surface of the decorative flooring (A).

At the joints (8) (9) other than the staggered side edges (6),
As can be seen from the figure, a gap (19) is formed, so that the adhesive (18) accumulates here.

In this embodiment, the notches (7) and (27) are present on the entire side edge of the decorative piece (2) in processing, but the adhesive (18) is manually applied only to the nailing portion (4). Since the amount of application is too much due to manual work, it is sufficient that the notches (7) and (27) are present only on the staggered side edges (6). Also this notch
If (7) is on either one of the two decorative floor coverings (A) that are adjacent in the length direction, the adhesive (18) can be collected here,
Notches (7) and (27) may be provided on the staggered side edges (6) on at least one side of the stepped portions (10) and (11) at both ends.

When the length of the decorative piece (2) is long, a required number of lines may be provided in the width direction in the middle of both ends thereof. In this way, one cosmetic piece (2) appears to have a plurality of cosmetic pieces. Further, a plurality of decorative pieces (2) joined in the length direction may be arranged in parallel on one substrate (1).

Further, in this embodiment, the joints (8) and (9) are formed for tongue-and-groove, but they may be phase-notch and the like.

The top surface of the decorative piece (2) may be provided on both edges of the top surface.

Effect of the Invention According to the present invention, while using a relatively large-sized decorative flooring as in the past, a large number of strip-shaped narrow decorative flooring are used to form an irregular scale floor surface. Can be obtained with the same construction efficiency as before.

In addition, the staggered side edges of the decorative pieces of adjacent decorative flooring materials that are adjacent to each other are directly butted against each other, but notches at the bottom of the staggered side edges of at least one side of the stepped portions at both ends. The adhesive remaining on the upper surface of the nail striking part is pressed against the lower surface of the decorative material at the insertion part and flows into it, where it accumulates, so the adhesive applied to the nail striking part during construction is There is no danger of protruding to the upper surface.

Further, since the decorative material does not protrude extremely extremely from the substrate, the edge of the decorative material is not chipped when the decorative flooring material is transported or otherwise handled.
