Description

[Detailed description of the invention] Industrial field of application This invention relates to a decorative flooring material that is directly attached to a concrete floor or installed on a flooring substrate such as thick wood, plywood, particle board, etc.

BACKGROUND ART Conventionally, rectangular irregular pattern decorative flooring materials have been known as decorative flooring materials.

Problem to be Solved by the Invention As shown in Figure 6, when a large number of conventional decorative flooring materials B are installed closely together on a subfloor, there is a straight seam on the short side of each decorative flooring material B. 21 occurred, and I was frustrated that I could not obtain an irregular pattern on the entire floor.

Of course, we use rectangular decorative flooring materials,
It is also possible to consider a construction method in which strips of flooring material that are adjacent in the width direction are staggered in the length direction and arranged closely in order to obtain an irregular pattern over the entire floor surface, but such construction method is extremely inefficient. It's bad and unrealistic.

The purpose of this invention is to provide a decorative flooring material that can provide an irregular pattern on the entire surface of the floor without impairing construction efficiency, and that does not cause damage to the decorative material during packaging and transportation.

Means for Solving the Problems In order to achieve the above object, the decorative flooring material according to this invention includes a substrate and a decorative flooring material consisting of a plurality of parallel closely spaced rectangular decorative pieces adhered to the substrate. The ends of the decorative pieces are staggered in the longitudinal direction in a step-like manner when viewed from the plane, and one edge of the board is made to protrude from the decorative material to form a nailing part. A nailing part insertion part of the adjacent flooring material is formed by retracting the other side edge from the decorative material, and by providing both a protruding part and a recessed part with respect to the decorative material at each end of the board, the nailing part is retracted from the decorative material. A nailing part insertion part is formed at both ends of the flooring material, and a nailing part is formed at least in the part where the most protruding decorative piece in the length direction among the plurality of parallel close-contact rectangular decorative pieces exists. is made to exist.

As the substrate, plywood with a thickness of 2 to 9 mm is suitable, but particle board or medium density fiberboard with a thickness of 3 to 12 mm is also preferable, and other inorganic boards, synthetic resin boards, or metal boards can also be used. Note that 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 can be obtained by pasting a decorative veneer with a thickness of 0.2 to 3.0 mm on a plywood with a thickness of 2.5 to 7.0 mm and vertically dividing it into the required number, but the method described above Instead of plywood, medium-density fiberboard can also be used.

The appropriate width of the nailing part is 20 to 70 mm.

Function When installing a large number of decorative flooring materials based on this invention on a subfloor in close contact with each other, nails are driven into the nailing areas of the decorative flooring so that they reach the subfloor, and then adhesive is applied manually to the nailing areas. After application, the joints of adjacent decorative flooring materials are aligned, and the nailing part insertion part of one decorative flooring material is matched with the nailing part of the other decorative flooring material. As a result, both ends of the plurality of decorative pieces constituting the decorative material are staggered in the longitudinal direction in a step-like manner when viewed from a plane, so that an irregular pattern can be obtained over the entire floor. Then, the nailing part and the nailing part insertion part of the adjacent flooring material are placed on one side of the board in the length direction, and the nailing part insertion part and the nailing part of the adjacent flooring material are placed on the same other side of the board in a reverse relationship. are formed respectively, and a nailing part is provided at least in the part where the most protruding decorative piece in the longitudinal direction among the plurality of parallel rectangular decorative pieces is present, so that this decorative piece is not easily removed during packaging and transportation. There is no risk of the ends of the pieces breaking or chipping.

Embodiment An embodiment of this invention will be described below with reference to the drawings. In this specification, "left and right" refers to the left and right sides of FIG. 1, and "front and back" refers to the bottom and top of the same figure.

The decorative flooring material shown in FIGS. 1 and 2 includes a substrate 1 and a decorative material 3 made up of a plurality of closely-aligned rectangular decorative strips 2 adhered onto the substrate 1. Both end portions of the decorative pieces 2 adjacent in the width direction are staggered in the length direction in a stepwise manner when viewed from a plane. Further, the board 1 is made to protrude from the decorative material 3 at the front to form a nailing part 4, and the board 1 is retracted from the decorative material 3 at the rear to form a nailing part insertion part 5 of the adjacent flooring material. There is. By providing both a protruding part and a retracting part with respect to the decorative material at each end 10, 11 of the substrate 1, a nailing part 4 and a nailing part insertion part 5 are formed at both ends of the flooring material, respectively. A nailing portion 4A is provided in the portion where the decorative piece 2 protrudes most in the length direction. Since the decorative material 3 of the decorative flooring material A in FIG. , Correspondingly, there are two nailing part insertion parts 4 and one nailing part 5 on the right side, and each staggered side edge 6 on the left side has a nailing part 4.
However, a nailing part insertion part 5 is present in each staggered side edge part 6 on the right side.

As shown by the chain line in FIG. 1, there is no nailing part 4A in the part where the decorative piece 2 that protrudes most in the length direction exists, and instead there is a nailing part insertion part 5A of the adjacent flooring material. If so, there is a possibility that the end of the decorative piece 2 on top of the decorative piece 2 may be chipped during packaging and transportation. Note that even if the board 1 side is chipped, there is no problem because the chipped portion will not be visible from the front after the decorative floor board is installed. Adhesive pool notches 7 are formed in the entire side edges of the plurality of decorative pieces 2 constituting the decorative material 3, including the staggered side edges 6, excluding the staggered side edges 6. Around the decorative material 3, there are a joint part 8 made of a tenon and a joint part 9 made of a small hole, corresponding to the joint form of the adjacent flooring material A in the length direction or width direction.
is formed.

The stepped left end portion 10 of the board 1 is formed facing forward, and the stepped right end portion 11 is formed facing backward.
When viewed from a plane, the board is cut stepwise into two halves, and if the straight short sides 12 and 13 of the split halves 1A and 1B at both ends are opposed to each other, a board with the shape shown in Fig. 1 is obtained. 1 is obtained.

Note that there may be a gap between the two opposing linear short sides 12 and 13 as shown in the figure, or they may be in close contact with each other. You can use Imotsugi to make them close together.

3 and 4 show how to make the cosmetic piece 2. First, as shown in FIG. 3, joint parts 8 made of tenons are formed on two orthogonal sides of one decorative rectangular board 14, and joint parts 9 made of small holes are formed on the remaining two orthogonal sides. do. Next, a groove 16 is provided along a longitudinal line 15 dividing the width of the decorative rectangular plate 14 into three equal parts. Finally, the rectangular plate 14 is vertically 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 parts, the front and the rear, and becomes the adhesive reservoir cutout 7 of each decorative piece 2.

Although the notch 7 is present on the entire side edge of the decorative piece 2 due to processing, adhesive is only applied to the nailing part 4 by hand, and the amount of adhesive applied by hand may be too large. , it is sufficient that the notches 7 are present only on the staggered side edges 6.

When installing a large number of decorative flooring materials A on a floor base in close contact, nails 18 are driven into the nailing parts 4 of the decorative flooring material A so as to reach the flooring base 17, and then adhesive is manually applied to the nailing parts 4. Joint parts 8 and 9 of decorative flooring materials A that are adjacent in the length direction or width direction after being applied with
They are fitted together, and the nailing part insertion part 5 of one decorative flooring material A is matched with the nailing part 4 of the other decorative flooring material A after nailing.

FIG. 5 shows a plurality of decorative pieces 2 constituting the decorative material 3.
Since both end portions of each other are staggered in the longitudinal direction in a stepwise manner when viewed from the plane, when a large number of decorative flooring materials A are closely arranged, an irregular pattern is obtained over the entire floor.

In addition, when the length of the decorative piece 2 is long, a required number of lines or grooves may be provided in the width direction in the middle between both ends thereof. In this way, even one makeup piece 2 looks like there are multiple makeup pieces. Furthermore, a plurality of decorative materials 3 may be arranged in series on one substrate 1, and in this case, it is preferable for the decorative materials 3 to have different lengths as a random pattern. Furthermore, a plurality of decorative pieces 2 joined in the length direction may be arranged in parallel on one substrate 1, and in this case as well, it is more interesting to change the lengths of the plurality of decorative pieces 2 that are vertically joined. be.

Note that the stepped one end 10 and the stepped other end 1
If there are joints 8, 9 on the end faces of the flooring material 1, the longitudinal nailing portion 4 and the nailing portion insertion portion 5 of the adjacent flooring material are not necessarily required. In some cases, the upper surface of the decorative piece 2 is beveled with a design on both sides of the upper surface.

Effects of the invention According to this invention, while using relatively large-sized decorative flooring materials as in the past, a large number of narrow rectangular decorative flooring materials are used to create an irregularly patterned floor surface. can be obtained with the same construction efficiency as before, and there is no risk of damage to the decorative material during packaging and transportation.
