Description

[Technical Field]

[0001] The present invention relates to a floor finishing material unit that is easy to install and has a good appearance after installation, and to an installation method thereof. [Background technology]

[0002] Known floor finishing materials that are laid on the floor of a room include those made from solid wood (solid wood flooring) and those made from composite materials (a decorative material bonded to the surface of a base material such as plywood) (composite flooring).

[0003] The basic structure of these various floor finishing materials is a long, narrow rectangular plate-like member with indentations on all four sides (specifically, male indentations are formed on one long side and one short side of the floor finishing material, and female indentations are formed on the other opposite long side and other short side).

[0004] When laying a floor finishing material on a floor surface, first, the dimensions of the floor surface are measured and the number of floor finishing materials required to cover the floor surface is prepared.

[0005] Once the floor finishing materials are ready, they are temporarily arranged. The floor finishing materials to be placed along the wall are cut to the required length or width. When solid wood is used, the grain and color of each floor finishing material will vary, so it is advisable to temporarily arrange the floor finishing materials to check the overall balance. After the temporary arrangement, all floor finishing materials will be removed, and then the work of laying the floor finishing materials, which will be described later, will begin.

[0006] Next, we will briefly explain the installation work of floor finishing materials. Adhesive is applied to the backside of the floor finishing material (or to the subfloor material on the floor surface), and this is attached to the subfloor material. Then, nails or staples (hereinafter referred to as "nails, etc.") are driven diagonally into the corners of the upper surface of the male part of the floor finishing material attached to the subfloor material. This firmly fixes the floor finishing material to the subfloor material (see, for example, Patent Document 1).

[0007] The male short side of one floor covering material is joined to the female short side of the other floor covering material, and the other floor covering material is then fixed to the subfloor using adhesive and nails, as described above. This process is repeated until the floor covering materials are laid in a vertical line along their length. The floor covering materials can be laid on the subfloor starting from the wall or from the center of the room, and this can be chosen based on the shape of the room and ease of installation.

[0008] Once the first row of floor finishing materials has been laid, the second row of floor finishing materials is laid along the first row of floor finishing materials fixed to the subfloor. At this time, the floor finishing materials are laid in a vertical row, with the long side female (or long side male) of the second row of floor finishing materials joined to the long side male (or long side female) of the first row of floor finishing materials fixed to the subfloor. Once the second row of floor finishing is complete, floor finishing materials are laid in the same way for the third row and beyond. As mentioned above, floor finishing materials laid along the wall are cut to fit the width of the gap to the wall and laid as fitting members. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2023-148782 A (Page 10, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0010] As mentioned above, floor finishing materials that are installed along the wall are cut to fit the width of the gap to the wall, but if the gap to the wall is very narrow, for example, about 15 mm, cutting the floor finishing material to a narrow width to fit this narrow gap is an extremely difficult task.In particular, if the floor finishing material is narrow, such as 5 sun wide (145 to 151.5 mm), cutting the narrow floor finishing material to an even narrower width (for example, 15 mm wide) is an extremely difficult task even for an experienced person.

[0011] Also, when the gap to the wall surface is very narrow, for example, 15 mm, difficulties also occur during construction work. That is, the floor finishing material is fixed to the floor base material by driving in nails or the like. However, if the distance to the wall surface is too short, it is difficult to drive in nails or the like, and in some cases, the wall surface may obstruct the work and the driving-in work of nails or the like may not be possible at all. When fixing with nails or the like is not possible, the fixing of the floor finishing material to the floor base material is performed only by sticking with an adhesive. In this case, however, there is a concern that a space (so-called "floating") may occur between the floor finishing material and the floor base material due to insufficient adhesive strength, leading to problems with poor construction.

[0012] Furthermore, when the gap to the wall surface is very narrow, it also affects the appearance after construction. That is, as shown in FIG. 10, the wall surface WL of the room is not straight and may have a slight deflection A. In this case, if the floor finishing material installed along the wall is narrow, the slight deflection A of the wall surface WL becomes prominent, resulting in a problem that the appearance is impaired.

[0013] The present invention has been made in view of such conventional problems, and relates to a floor finishing material unit with good workability and excellent appearance after construction, and a construction method thereof.

Means for Solving the Problems

[0014] To achieve the above object, the present invention configures a floor finishing material set 10 as follows, for example, as shown in FIGS. 1 to 2. The floor finishing material set 10 includes a floor finishing material 12 for installation that is installed in the central portion of the floor base material of the room, and When in use, the width a storage floor finishing material 14 that is installed as a storage member between the long side 16a (16b) of the floor finishing material 12 for installation and the wall surface WL. It is cut to have the same dimension as the gap T. It has a storage floor finishing material 14 that is installed as a storage member along the wall. The width W1 of the floor finishing material 12 for installation and the Before cutting width W2 of the storage floor finishing material 14 have a relationship of W1 < W2 < 2W1. It is desirable that the surfaces of the floor finishing material 12 for installation and the storage floor finishing material 14 are smooth surfaces and chamfered on their four sides.

[0015] Moreover, the method for laying a floor finishing material unit according to the second invention is configured as follows, as shown in, for example, FIGS. A floor finishing material 12 to be laid in the center of the underfloor material of a room and a finishing floor finishing material 14 to be laid as a wall-side finishing member between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL are prepared. The width W2 of the finishing floor finishing material 14 is set to be larger than the width W1 of the floor finishing material 12 and smaller than twice the width W1 of the floor finishing material 12. Next, the floor finishing material 12 to be laid on the underfloor material is laid on the underfloor material until the widthwise gap T from the long side 16a (16b) of the floor finishing material 12 to be laid on the wall surface WL is larger than the width W1 of the floor finishing material 12 to be laid on the underfloor material and smaller than twice the length (2W1) of the width W1 of the floor finishing material 12 to be laid on the underfloor material. Next, the finishing floor material 14 is cut so that the width W2 of the finishing floor material 14 matches the gap T from the long side 16a (16b) of the final row of the floor finishing material 12 to the wall surface WL. Finally, the cut fitting floor finishing material 14 is laid as a fitting member in the gap T between the long side 16a (16b) of the final row of laying floor finishing material 12 and the wall surface WL. [Effects of the Invention]

[0016] In the present invention, the width W2 of the fitting floor finishing material 14 is set to be larger than the width W1 of the laying floor finishing material 12, but smaller than twice the width W1 of the laying floor finishing material 12. Therefore, after the laying floor finishing material 12 has been laid until the gap T between the long side 16a (16b) of the laying floor finishing material 12 and the wall surface WL is larger than the width W1 of the laying floor finishing material 12, but smaller than twice the length (2W1) of the width W1 of the laying floor finishing material 12, the laying floor finishing material 14 can be cut to fit the dimensions of the gap T and laid as a fitting member along the wall.

[0017] Here, the fitting floor finishing material 14 can be cut to a width dimension larger than the width W1 of the laying floor finishing material 12, so the cutting work is easy.

[0018] Furthermore, the gap T between the long side 16a (16b) of the last row of the floor finishing material 12 to be laid and the wall surface WL is larger than the width W1 of the floor finishing material 12 to be laid, so that sufficient working space can be secured for the work of driving nails etc. to fix the floor finishing material 12 to the floor base material, and workability is not impaired.

[0019] Furthermore, since the finish floor material 14 for attachment is wider than the finish floor material 12 for laying, slight deflection A on the wall surface is less noticeable and does not impair the appearance after construction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0021] The present invention will now be described with reference to the drawings, in which: Figure 1 shows a floor covering material set 10 used in the present invention.

[0022] As shown in this figure, the floor finishing material set 10 of the present invention is roughly composed of a plurality of floor finishing materials 12 for laying and a plurality of floor finishing materials 14 for fitting (one of each is shown in Figure 1).

[0023] The floor finishing material 12 for installation is a long, thin, plate-like member, and in this embodiment, a composite flooring is used in which decorative material is attached to the surface of a base material such as plywood or MDF (medium density fiberboard or medium specific gravity fiberboard), but solid wood may also be used.

[0024] Two sets of male and female indentations are formed around the four periphery of the floor finishing material 12. That is, male indentations 20a and 22a are formed on one long side 16a and one short side 18a of the floor finishing material 12, respectively, and female indentations 20b and 22b are formed on the other opposing long side 16b and other short side 18b, respectively.

[0025] In this embodiment, the width W1 of the floor finishing material 12 for installation is selected to be 5 inches wide (145 to 151.5 mm), but narrower or wider widths may also be used, and any width may be selected depending on the size and atmosphere of the room in which the floor finishing material set 10 is installed.

[0026] The standard length H1 of the floor finishing material 12 for installation is, for example, about 3 to 6 feet (1818 mm or 1820 mm), but is not limited to this length.

[0027] The top surface of the floor finishing material 12 is chamfered around all four edges. It is preferable that the surface of the floor finishing material 12 is smooth and free of irregularities (i.e., it is desirable that the surface of the floor finishing material 12 does not have decorative irregularities such as decorative grooves).

[0028] Each storage floor finishing material 14 is a plate-like member used for being installed as a "storage member" along the wall of the room. It has the same structure as the installation floor finishing material 12 except that its width W2 is different. That is, the storage floor finishing material 14 is a plate-like member wider than the installation floor finishing material 12, and two sets of male and female joint processes are performed on its four sides. Specifically, male joints 28a and 30a are respectively formed on one long side 24a and one short side 26a of the storage floor finishing material 14, and female joints 28b and 30b are respectively formed on the other long side 24b and the other short side 26b facing them. The surface of the storage floor finishing material 14 is a smooth surface without irregularities.

[0029] The width W2 of the storage floor finishing material 14 is set to be larger than the width W1 of the installation floor finishing material 12 and smaller than twice the width W1 of the installation floor finishing material 12 (2W1) (see Fig. 2). That is, a relationship of W1 < W2 < 2W1 is established between the width W2 of the storage floor finishing material 14 and the width W1 of the installation floor finishing material 12.

[0030] The storage floor finishing material 14 is installed as a "storage member" along the wall between the long side 16a (16b) of the installation floor finishing material 12 in the final row and the wall surface WL as described later. As described above, its width W2 is set to be larger than the width W1 of the installation floor finishing material 12 and smaller than twice the width W1 of the installation floor finishing material 12 (2W1). And during use, it is cut and used so that its width dimension matches the gap T between the long side 16a (16b) of the installation floor finishing material 12 and the wall surface WL (see Fig. 5). Therefore, the width W2 of the storage floor finishing material 14 needs to be set to be larger than the gap T between the long side 16a (16b) of the installation floor finishing material 12 and the wall surface WL.

[0031] The length H2 of the storage floor finishing material 14 is set to be equal to the length H1 of the installation floor finishing material 12. Also, chamfering is performed on the four sides of the upper surface of the storage floor finishing material 14, and its surface is a smooth surface without irregularities, similar to the installation floor finishing material 12.

[0032] A method for laying the floor finishing material set 10 configured as above onto the underfloor material of a room will now be described. The floor finishing material set 10 can be laid starting from the center of the room or from the edge (wall) of the room. Here, the former case will be described.

[0033] First, measure the dimensions of the room and draw a reference line M (see Figure 3) in the center of the room, and calculate and prepare the required number of floor finishing materials 12 for installation and floor finishing materials 14 for fitting.

[0034] Although there is no particular rule as to the direction in which the floor finishing material 12 and the finishing material 14 are laid, they are generally laid in the longitudinal direction of the room. Therefore, it is desirable to draw the reference line M as a line extending in the longitudinal direction of the room.

[0035] Next, the prepared floor finishing materials 12 are temporarily arranged one by one in a vertical row (longitudinal direction) along the reference line M (FIG. 3).

[0036] Adjacent pieces of floor finishing material 12 in the longitudinal direction are joined together at the male joint 22a on the short side 18a and the female joint 22b on the short side 18b (see circle in Figure 3). At this time, to prevent warping or pushing up due to expansion and contraction of the floor finishing material 12, it is preferable to leave a gap (clearance) of about 0.2 to 0.5 mm between adjacent pieces of floor finishing material 12.

[0037] When the floor finishing material 12 is laid lengthwise in a row on the floor surface of a room, and the longitudinal gap S from the short side 18a (18b) of the floor finishing material 12 to the wall surface WL becomes shorter than the length H1 of the floor finishing material 12, it becomes impossible to lay any more floor finishing material 12. In this case, the floor finishing material 12 is cut to fit the dimensions of the gap S, and the cut piece 12P is laid in the gap S.

[0038] Once the vertical installation of the floor finishing materials 12 is complete, the second and subsequent rows are installed in the same manner. Adjacent floor finishing materials 12 are joined widthwise by joining the male section 20a on the long side 16a with the female section 20b on the long side 16b. As with the short sides 18a and 18b, it is preferable to leave a gap (clearance) of approximately 0.2 to 0.5 mm between adjacent floor finishing materials 12. In this example, the floor finishing materials 12 are installed with the joints offset alternately, a so-called "fixed length installation" method is used. However, a "random installation" method, in which the joints are offset from one another for each row, may also be used.

[0039] Then, as shown in Figures 4 and 5, the floor finishing material 12 is laid down until the gap T between the long side 16a (16b) of the laying down floor finishing material 12 and the wall surface WL is larger than the width W1 of the floor finishing material 12 and smaller than twice (2W1) the width W1 of the floor finishing material 12, and then the fitting floor finishing material 14 is cut so that its width W2 is the same length (dimension) as the gap T between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL.

[0040] Then, the cut fitting floor finishing material 14 is stretched as a fitting member into the gap T between the long side 16a (16b) of the final row of fitting floor finishing material 12 and the wall surface WL.

[0041] Once the temporary alignment of the installation floor finishing materials 12 and the fitting floor finishing materials 14 is completed as described above, they are temporarily removed and the installation floor finishing materials 12 and the fitting floor finishing materials 14 are fixed to the subfloor material using adhesive and nails. As a result, the entire floor surface is laid with the installation floor finishing materials 12 and the fitting floor finishing materials 14. Of course, the installation floor finishing materials 12 and the fitting floor finishing materials 14 may be fixed directly to the subfloor material without temporary alignment. Furthermore, a clearance of approximately 0.5 mm to 3 mm may be provided between the installation floor finishing materials 12 and the fitting floor finishing materials 14 and the wall surface WL (in the lengthwise and widthwise directions) to absorb expansion and contraction due to temperature, humidity, etc.

[0042] The top surfaces of the installation floor finishing material 12 and the fitting floor finishing material 14 are each chamfered around all four edges, so that this chamfering creates small grooves 28 at the boundaries between adjacent installation floor finishing materials 12 and at the boundaries between adjacent installation floor finishing materials 12 and fitting floor finishing materials 14 (see Figures 6 and 7).

[0043] Thus, according to this embodiment, the width W2 of the fitting floor finishing material 14 is set to be larger than the width W1 of the laying floor finishing material 12, but smaller than twice the width W1 of the laying floor finishing material 12. Therefore, after laying the fitting floor finishing material 12 until the gap T between the long side 16a (16b) of the laying floor finishing material 12 and the wall surface WL is larger than the width W1 of the laying floor finishing material 12, but smaller than twice the length (2W1) of the width W1 of the laying floor finishing material 12, the fitting floor finishing material 14 can be cut to fit the dimensions of the gap T and laid as a fitting member along the wall.

[0044] Here, the fitting floor finishing material 14 can be cut to a width dimension larger than the width W1 of the laying floor finishing material 12, so the cutting work is easy.

[0045] Furthermore, the gap T between the long side 16a (16b) of the last row of the floor finishing material 12 to be laid and the wall surface WL is larger than the width W1 of the floor finishing material 12 to be laid, so that sufficient working space can be secured for the work of driving nails etc. to fix the floor finishing material 12 to the floor base material, and workability is not impaired.

[0046] Furthermore, since the width W2 of the floor finishing material 14 for fitting is wider than the width W1 of the floor finishing material 12 for laying, by using this as a fitting member at the wall side, slight deflection A of the wall surface WL is less noticeable and the appearance after construction is not impaired.

[0047] Furthermore, the floor finishing material 12 that is laid in the room has a constant width W1, which, combined with the chamfers provided around the four peripheries of its upper surface, provides a floor surface with a neat and tidy impression.

[0048] In the above-described embodiment, the surface of the fitting floor finishing material 14 is smooth, but as shown in Figure 8, a decorative groove 30 may be provided in the center of the fitting floor finishing material 14'. The decorative groove 30 is formed in the same shape as the recessed groove 28 formed at the boundary between adjacent fitting floor finishing materials 12 or at the boundary between adjacent fitting floor finishing materials 12 and fitting floor finishing material 14'.

[0049] The width W2 of the installation floor finishing material 14' in this embodiment is set to twice the width W1 (2W1) of the installation floor finishing material 12. This ensures that the decorative groove 30 is positioned at the same width (W1) as the installation floor finishing material 12, regardless of whether it is cut from the male 30a side or the female 30b side. Because the decorative groove 30 is formed to have the same shape as the recessed groove 28, when the floor finishing material set 10 is installed in a room, the decorative groove 30 and the recessed groove 28 blend together to create a natural finish. However, if the room has an irregular shape or the decorative groove 30 is close to the wall surface WL, this may cause problems such as the irregular shape of the room or the warp A of the wall surface WL becoming noticeable, which is not desirable.
