Description

  The present invention relates to a wooden floor material capable of easily performing a good-looking floor finish.

  A long rectangular plate-like wood board with a decorative joint on the surface has excellent properties such as texture, cushioning properties and heat insulation, and is widely used as a flooring material for buildings such as houses, stores and offices. . And most of these wooden flooring materials form concave or convex fruits all around the end of the mouth, and are joined by joining the ends together by actual rowing, and are glued and glued to the floor base. The floor finishing layer is formed by adhering.

  In recent years, the quality of decorative sheet materials excellent in handling and cost has been improved, and there is a tendency that decorative sheet finishing is often used as a surface finishing material for wooden flooring instead of the conventional veneer. As a result, many of the wide-width joint patterns, which had been refrained from the high cost of the veneer finish, have come to be used. In addition, a combination of a wide-width joint joint and a narrow-width joint joint is used, and further, it goes straight to the makeup joint. There is a tendency to improve decoration by providing random joints in both the vertical and horizontal directions, such as irregularly arranging the intersection joints.

  In this way, the design characteristics are further improved by adopting random joint placement in a single wooden flooring, but if the wooden flooring of the same appearance produced industrially is continuously laid, for example, it is adjacent It was found that the floor finish as a whole has a repeated pattern such as the positions of the joint joints of the wooden flooring, and as a result there is a limit to the improvement of the design.

  Therefore, as shown in FIG. 5, it is conceivable to prevent the positions of the cross joints from being aligned by shifting the longitudinal ends e of the wooden flooring material a in a staircase shape (for example, patents). Reference 1).

JP-A-5-331994

  However, if the ends of the wooden flooring are shifted and attached each time, depending on the site, the wooden flooring will be arranged in a non-uniform manner, resulting in a gap in the end of the floor, such as a gap at the end of the floor finish. easy. In addition, in order to prevent this problem, when installing a pre-set deviation dimension while measuring with a measure, the efficiency of laying work is reduced, and inevitable errors caused by measurement operations, alignment work, etc. accumulate, There is a problem that a slight gap is generated at the end of the floor finish.

  The present invention is based on the fact that the male part is provided with a cutout part that is partially cut out in the middle, and the female fruit is provided with a cutout part that is partially cut out in the middle and substantially the same length as the lacking part. The goal is to provide a wooden flooring that can be easily finished without being out of order.

  In order to achieve the above object, the invention according to claim 1 is a wooden floor material in which the end portion in the longitudinal direction is laid out in a laminating manner with the displacement of the displacement dimension shifted, and an elongated rectangular plate-shaped substrate; A male fruit projecting from one side of the base and a female fruit recessed from the other side of the base, the male fruit being partially cut out in the middle And the female fruit is partially interrupted in the middle and has a discontinuity having approximately the same length as the lack, and a dimension La from the longitudinal end of the substrate to the center of the lack, A difference (La−Lb) from the dimension Lb to the center of the discontinuity is formed to be approximately equal to the displacement dimension.

  In the invention according to claim 2, a plurality of the lacking portions are provided in the longitudinal direction of the substrate, and in the invention according to claim 3, both ends of the lacking portion are in the front end of the substrate. It spreads obliquely from the outside toward the outside and forms a trapezoidal shape in plan view.

  In the invention according to claim 4, the discontinuous portion has both ends in the longitudinal direction gradually approaching outward from the groove bottom of the female fruit, forming a trapezoidal shape in plan view, and in the invention according to claim 5, The displacement dimension is equal to the interval of small joists arranged at equal intervals between the heating elements for floor heating.

  In laying the wooden flooring of the invention according to claim 1, in order to fit the male and female facing each other on the adjacent wooden flooring and arrange them without gaps, the lack of males and the cuts of females Need to be fitted. Therefore, the wooden flooring laid adjacent to each other is arranged in a labyrinth with a predetermined displacement dimension shifted, thereby making the entire floor finish surface highly random and decorative due to the pattern provided on the surface. Can be configured. Moreover, the installation work can be performed efficiently without requiring skill. Further, since the laying is performed according to the designed arrangement, there is no possibility of an error in the accommodation such as a gap at the end due to accumulation of errors in the attachment position.

  In the invention according to claim 2, since plural kinds of displacement dimensions are set, it is possible to lay various arrangements with one kind of wooden flooring, according to the composition of joint pattern, balance with wall finish, etc. Thus, the finish variation can be selected, and an excellent design can be obtained, and the invention according to claim 3 is for fitting and positioning the lacking part of the trapezoidal shape in plan view and the cut part of the female fruit when laying. In addition, the work efficiency is good and the accuracy of the mounting position is improved, so that a floor finish with high design properties can be obtained.

  In the invention according to claim 4, since the discontinuous portion of the trapezoidal shape in plan view and the lack of male part are fitted and positioned at the time of laying, the laying work is made efficient and the accuracy of the mounting position is improved. With the configuration according to the invention according to No. 5, since the joint portions between the ends in the longitudinal direction of the substrate can be laid and aligned with the small joists, the attachment state can be stabilized, and the fixing tool is accidentally driven into the heating element. Trouble can be prevented.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the wooden flooring 1 is provided with an elongated rectangular plate-like substrate 2 that constitutes a main body portion, and a male 3 that protrudes from the mouth end surface F of the substrate 2. With female fruit 4. Then, a plurality of wood floor materials 1 are used, and the end portions in the longitudinal direction are sequentially laid in a laminar shape with a predetermined displacement dimension shifted to form a floor finish surface.

  The substrate 2 includes a base layer 2A and a decorative layer 2B laminated on the base layer 2A. The base layer 2A constitutes the structural base of the wooden flooring 1 and has an elongated rectangular plate shape. The base layer 2A may be composed of a single layer. However, when the odd ply is composed of a laminated body in which the fiber directions are alternately arranged, the vertical and lateral directions such as bending strength and warpage are offset to obtain stable quality. It is preferable in that it can be performed. The substrate 2 is formed to have a longitudinal direction of, for example, about 1000 to 3000 mm, in this embodiment, 1818 mm, and a width direction of, for example, about 150 to 600 mm, and in this embodiment, 303 mm. Moreover, thickness is about 6-20 mm, for example, and is 12 mm in this form.

  When the base layer 2A is composed of a single layer, it is made of wood such as cedar, pine, firewood, lawan, cherry, etc., and other wood boards such as particle board, hard board, MDF (medium density fiberboard), insulation board, etc. Use laminated wood. On the other hand, when composed of a laminate, various plywoods such as lauan plywood, cedar plywood, rice pine plywood, LVL (single plate laminated material), OSB (oriented strand board), etc. are used. In addition, if a cushion layer made of urethane foam, polyethylene foam or the like or a sound insulation layer made of olefin resin is laminated on the bottom surface, the sound insulation performance is improved, so that it can be suitably used as an upper floor finish. .

  The decorative layer 2B is formed to cover substantially the entire upper surface of the base layer 2A. The decorative layer 2B is, for example, a melamine / urea co-condensation bond with a veneer obtained by slicing raw wood such as oak, cherry, teak, zelkova, tochi, sen, hippo and beech into a thickness of about 0.2 to 1.0 mm. It is formed by adhering to the base layer 2A using an agent, a phenolic adhesive, an amino adhesive, a urea adhesive, etc., and further covering it with a coating film, a protective film or the like. The decorative layer 2B can also be formed by sticking an olefin resin such as polyethylene, polypropylene, ethylene vinyl acetate resin (EVA), a melamine resin, a polyester resin or other decorative sheet material to the base layer 2A. In addition, the decorative layer 2B can be formed by applying an unsaturated polyester resin after the decorative paper is adhered to the base layer 2A, or directly on the surface of the base layer 2A. It may also be formed by painting an alkyd paint, an acrylic paint or the like.

  Further, as shown in FIG. 2, a joint pattern M along the longitudinal direction is formed on the decorative layer 2B, imitating the appearance of a conventional board. Since the wide veneer is costly, a uniform narrow joint pattern M is mainly formed in the veneered decorative layer 2B. However, as described above, since quality improvement has progressed in recent years and a high-quality decorative sheet material having an excellent appearance has been provided and it has become possible to freely design cosmetic joints of any width, various wide joint joint widths can be combined as appropriate. A highly decorative joint pattern M in which orthogonal cross joints are randomly arranged is formed.

  The male fruit 3 protrudes over the entire length F of the side face F of one side of the substrate 2, and has a longitudinal section having the same shape that is linearly continuous along the longitudinal direction of the substrate 2. . In this embodiment, the male fruit 3 continuous with the male fruit 3 on the side of the substrate 2 is also formed on the end face F of the one end portion of the substrate 2. Further, the male body 3 of the present embodiment has a substantially rectangular shape whose longitudinal section projects outward from the mouth end surface F, the tip end surface is formed in an arc shape, and is arranged at a substantially central height position of the end face F. ing. The male fruit 3 has a protrusion dimension of about 4 to 15 mm from the end face F, and is formed by an electric rotary cutting tool when processing the end face of the base layer 2A.

  Further, as shown in FIGS. 2 and 3, the male part 3 on the side of the substrate 2 is formed with a lacking part 5 in which a part thereof is cut out in the intermediate part. The lacking portion 5 of the present embodiment has enlarged inclined surfaces 7 and 7 whose both ends in the longitudinal direction extend obliquely outward from the end face F, and are formed in a trapezoidal shape in plan view. That is, the width in the longitudinal direction of the lacking portion 5 gradually increases from the inside toward the outside.

  Further, the lacking portion 5 is formed such that the center (the intermediate point in the longitudinal direction) is separated from the one end face (hereinafter referred to as the reference end face E) of the substrate 2 by La1, and in this embodiment, La1 is 453 mm. Illustrated.

  The female fruit 4 has a linearly continuous groove shape, and is recessed on the other end of the substrate 2 over the entire front end F over the entire length. In this embodiment, a female fruit 4 that is continuous with the female fruit 4 on the side portion is formed on the end face F of the other end of the substrate 2. The female seed 4 is formed by mating with the opposing male seed 3 of the adjacent wooden flooring 1 when a plurality of the wooden flooring 1 is continuously laid and the floor finishing is performed. Accordingly, the female fruit 4 is formed in a size and position that can be closely fitted with the male fruit 3.

  Further, as shown in FIGS. 1 and 3, the female fruit 4 formed on the side portion of the substrate 2 is formed with a discontinuous portion 6 in which a part thereof is partially interrupted at the intermediate portion. That is, in the discontinuous portion 6, a part of the groove-like female fruit 4 is discontinued, and a flat top end F that is continuous in the thickness direction is formed. The discontinuous portion 6 is formed in the longitudinal direction so as to have substantially the same length as the lacking portion 5, and in this embodiment, both ends in the longitudinal direction contract obliquely outward from the groove bottom of the female fruit 4. The reduced inclined surfaces 8 and 8 are formed in a trapezoidal shape in plan view. That is, the width in the longitudinal direction of the discontinuous portion 6 gradually decreases outward from the groove bottom of the female fruit 4. In the present embodiment, the discontinuous portion 6 and the lacking portion 5 have substantially the same length in the longitudinal direction when the male 3 and the female 4 are fitted to form an actual row. It means that the enlarged inclined surfaces 7 and 7 and the reduced inclined surfaces 8 and 8 of the female fruit 4 are formed to overlap each other without a gap. Further, the interrupted portion 6 of the female fruit 4 is formed such that the center (intermediate point in the longitudinal direction) is separated from the reference end face E by Lb, and in this embodiment, Lb is 150 mm.

  Further, the difference between La and Lb (La−Lb) is formed approximately equal to the displacement dimension. That is, the missing part 5 of the male fruit 3 and the discontinuous part 6 of the female fruit 4 are formed at positions where the intervals from the reference end surface E are different from each other in the displacement dimension. Thus, when constructing a floor finish by continuously laying a plurality of wooden flooring materials 1, mating male and female seeds 3 and 4 facing each other in adjacent wooden flooring materials 1 in contact with the sides in the longitudinal direction. When forming the actual row, it is necessary to fit the lacking part 5 of the male fruit 3 and the discontinuous part 6 of the female fruit 4 in order to eliminate the gap between the two. For this reason, the adjacent wooden flooring 1 is laid out in an orderly manner, with a positional deviation corresponding to the displacement dimension, which is the difference between La and Lb, forcibly produced.

  For example, in FIG. 2, the lacking portion 5 formed in the dimension of La1 (453 mm) from the reference end surface E and the cut-out portion 6 formed in the dimension of Lb (150 mm) from the reference end surface E face each other, and are offset. A state in which the lateral dimension (303 mm) is displaced is disclosed. And as shown to FIG. 4 (A), when the lacking part 5 and the discontinuous part 6 which face each other fit, the adjacent wooden flooring 1 is laid in the labyrinth form which the displacement dimension (303 mm) position shifted. . In this way, in floor finishing construction, it is not necessary to measure the displacement dimension using a measure, etc., and without adjusting the position to match the displacement dimension, it can be laid in a laminar manner according to the predetermined displacement dimension . As a result, the pattern provided on the surface can form a random and highly decorative shape as the entire floor finish surface, and the laying operation is simple without fitting the male fruit 3 and the female fruit 4. It can be done efficiently. In addition, since it can be laid at the designed position, there will be no gaps in the fit such as a gap at the end.

  In the present embodiment, as shown in FIG. 2, the case where the missing portion 5 is formed farther from the reference end face E than the discontinuous portion 6 is exemplified (when La> Lb). However, the present invention is not limited to this, and the discontinuous portion 6 may be formed farther from the reference end face E than the missing portion 5 (when La <Lb).

  As described above, in this embodiment, the lacking part 5 of the male fruit 3 has a trapezoidal shape in which both ends are obliquely expanded outward from the mouthpiece surface F, and the discontinuous part 6 of the female fruit 4 has both ends. It forms a trapezoidal shape in plan view that gradually approaches from the groove bottom of the female fruit 4 toward the outside. For this reason, the enlarged inclined surface 7 of the trapezoidal lacking portion 5 or the reduced inclined surface 8 of the discontinuous portion 6 can be guided to an accurate position as a guide for each other at the time of fitting. The efficiency can be improved and the position accuracy can be improved.

  Further, in this embodiment, as shown in FIG. 2, the lacking portion 5 has a plurality of La2, La3, and La4 in the longitudinal direction of the substrate 2 in addition to the La1 dimension from the reference end surface E. It is spaced along. In this embodiment, the La2, La3, and La4 are 604.5 mm, 756 mm, and 1059 mm, respectively. Then, instead of the lacking portion 5 formed in the La1, as shown in FIG. 4B, by fitting the lacking portion 5 formed in the La2 and the discontinuous portion 6, the displacement dimension (La2- Lb) can be laid in a lame manner with a 454.5 mm position shift. Further, as shown in FIG. 4 (C) or (D), when the lacking portion 5 and the discontinuous portion 6 formed in La3 or La4 are fitted, the displacement dimension is large and the positional relationship is shifted by 606 mm or 909 mm. Can be laid. In this way, when a plurality of missing portions 5 having different dimensions from the reference end face E are provided, they can be laid out with different dimensional positions shifted, so that a variety of changes can be made while using one kind of wooden flooring 1. The floor finish of the exterior is configured, and the finish of various variations can be selected according to the balance of the floor finish surface area, application, wall finish, etc., and excellent design properties can be obtained.

  When the wooden flooring 1 is used for finishing a floor equipped with floor heating, as shown in FIG. 1, a heating element comprising a floor heating panel 9A in which a hot water pipe 22 is embedded in a substrate 21 such as a particle board or plywood. 9 is laid on the small joists 10 arranged at equal intervals D according to the module of the heating element 9. And the wooden flooring 1 of this embodiment is formed so that the displacement dimension (La-Lb) is equal to the interval D of the small joists 10. That is, for example, while the interval D of the small joists 10 is 303 mm, in this embodiment, as described above, Lb is 150 mm, La1 is 453 mm, and the displacement dimension is 303 mm. (La−Lb) is equal to the interval D of the small joists 10. Therefore, by aligning the starting end of the wooden flooring 1 to be laid continuously on the small joist 10, all the places where the ends in the longitudinal direction of the substrate 2 constitute the actual rowing are joined together. Since it matches the small joist 10, the wooden flooring 1 is stably fixed. Moreover, in the actual rowing part, the wooden flooring 1 can be nailed and bonded to the small joists 10 to increase the mounting strength, and the trouble of accidentally driving the fixing tool into the heating element 9 can be prevented. it can.

  Note that the above description exemplifies an embodiment of the present invention, and the technical scope of the present invention is not limited to this.
