Description

Technical Field

[0001] The present invention relates to a floor finishing material unit with good workability and excellent appearance after construction, and a construction method thereof.

Background Art

[0002] As floor finishing materials laid on the floor surface of a room, those made of solid wood (solid wood flooring) and those made of composite materials (materials obtained by laminating a decorative material on the surface of a base material such as plywood) (composite flooring) are known.

[0003] The basic structure of these various floor finishing materials is an elongated rectangular plate-like member, and the four sides thereof are subjected to solid processing (specifically, male joints are formed on one long side and one short side of the floor finishing material, respectively, and female joints are formed on the other long side and the other short side facing these).

[0004] When laying the floor finishing material on the 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] When the preparation of the floor finishing materials is complete, a temporary arrangement of the floor finishing materials is carried out. The floor finishing materials arranged along the wall are cut to the required length dimension or width dimension. When solid wood is used, since the grain and color are different for each floor finishing material, it is desirable to carry out a temporary arrangement of the floor finishing materials to check the overall balance. After the temporary arrangement is carried out, all the floor finishing materials are removed once, and then the work of laying the floor finishing materials described later is carried out.

[0006] Next, the work of laying the floor finishing material will be briefly described. An adhesive is applied to the back surface of the floor finishing material (or the floor base material on the floor surface), and this is attached to the floor base material. Then, nails or staples (hereinafter referred to as "nails, etc.") are driven obliquely into the upper corner of the male joint of the floor finishing material attached to the floor base material. Thereby, the floor finishing material is firmly fixed to the floor base material (see, for example, Patent Document 1).

[0007] As described above, other floor finishing materials are fixed to the subfloor using adhesive and nails, while joining the short-side male tongues of the floor finishing materials to the short-side female tongues of the other floor finishing materials. This process is repeated to lay the floor finishing materials in a single vertical line along the length of the floor. Note that the installation of floor finishing materials to the subfloor can be started from the wall or from the middle of the room, and the choice should be made arbitrarily based on the shape of the room and ease of installation.

[0008] Once the first row of floor finishing material has been laid, the second row of floor finishing material is laid along the first row, which is fixed to the subfloor. At this time, the floor finishing material is laid in a single vertical line, connecting the long-side male (or long-side female) tongue of the second row of floor finishing material to the long-side female (or long-side male) tongue of the first row of floor finishing material which is fixed to the subfloor. Once the second row is laid, the third row and subsequent rows are laid in the same manner. As mentioned above, the width of the floor finishing material laid along the wall is cut to match the gap to the wall surface and then laid as a fitting component. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Japanese Patent Publication No. 2023-148782 (page 10, Figure 1) [Overview of the project] [Problems that the invention aims to solve]

[0010] As mentioned above, floor finishing materials that are installed along walls are cut to fit the gap between them and the wall. However, if the gap is very narrow, for example, around 15 mm, cutting the floor finishing material to fit this narrow gap is an extremely difficult task. In particular, if the floor finishing material is narrow, such as 5 sun wide (145-151.5 mm), cutting it to an even narrower width (for example, 15 mm) is an extremely difficult task, even for a skilled worker.

[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 interfere with the work and the driving-in work itself may not be possible. When fixation with nails or the like is not possible, the fixation of the floor finishing material to the floor base material is performed only by pasting with an adhesive. In this case, there is also a concern that a space (so-called "lifting") 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 may not be 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, as shown in Figs. 1 to 2 for example, the floor finishing material set 10 is configured as follows. 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 a storage floor finishing material 14 that is installed as a storage member along the wall between the long side 16a (16b) of the floor finishing material 12 for installation and the wall surface WL. The width W1 of the floor finishing material 12 for installation and the 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] Furthermore, the method for laying the floor finishing material unit according to the second invention was configured as follows, for example, as shown in Figures 3 to 7. Prepare a floor finishing material 12 for installation, which is to be installed in the central part of the floor subfloor of the room, and a finishing material 14 for installation, which is to be installed as a finishing member at the wall edge between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL. The width W2 of the 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 is laid onto the subfloor until the gap T in the width direction from the long side 16a (16b) of the floor finishing material 12 laid onto the subfloor to the wall surface WL is greater than the width W1 of the floor finishing material 12 and less than twice the length of the width W1 of the floor finishing material 12 (2W1). Next, the finishing floor material 14 is cut so that its width W2 matches the gap T from the long side 16a (16b) of the last row of floor finishing material 12 to the wall surface WL. Finally, the cut floor finishing material 14 is installed as a finishing member into the gap T between the long side 16a (16b) of the last row of floor finishing material 12 and the wall surface WL. [Effects of the Invention]

[0016] In this invention, the width W2 of the finishing floor material 14 is set to be greater than the width W1 of the floor finishing material 12, and less than twice the width W1 of the floor finishing material 12. Therefore, after laying the floor finishing material 12 until the gap T between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL is greater than the width W1 of the floor finishing material 12, and less than twice the length of the width W1 of the floor finishing material 12 (2W1), the finishing floor material 14 can be cut to the dimensions of the gap T and then laid as a finishing member at the wall.

[0017] Here, the floor finishing material 14 for installation can be cut to a width larger than the width W1 of the floor finishing material 12 for laying, making the cutting process easier.

[0018] Further, since the gap T between the long side 16a (16b) of the floor finishing material 12 for tucking and the wall surface WL is larger than the width W1 of the floor finishing material 12 for tucking, sufficient working space required for driving nails or the like to fix the floor finishing material 12 for tucking to the floor base material can be secured, and the workability is not impaired.

[0019] Furthermore, since the storage floor finishing material 14 is wider than the tucking floor finishing material 12, a slight deflection A of the wall surface is less noticeable and does not impair the appearance after construction.

Modes for Carrying Out the Invention

[0021] Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a view showing a floor finishing material set 10 used in the present invention.

[0022] As shown in this figure, the floor finishing material set 10 according to the present invention is generally composed of multiple floor finishing materials 12 for installation and multiple floor finishing materials 14 for finishing (each is shown individually in Figure 1).

[0023] The floor finishing material 12 for installation is a long, narrow, plate-like member. In this embodiment, a composite flooring is used, which consists of a base material such as plywood or MDF (medium-density fiberboard or medium-density fiberboard) with a decorative material laminated to its surface. However, solid wood may also be used.

[0024] The floor finishing material 12 for installation has two sets of male and female joints on all four sides. Specifically, male joints 20a and 22a are formed on one long side 16a and one short side 18a of the floor finishing material 12, and female joints 20b and 22b are formed on the other long side 16b and the other short side 18b opposite to these.

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

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

[0027] The floor finishing material 12 for installation has chamfered edges on all four sides of its upper surface. Furthermore, it is preferable that the surface of the floor finishing material 12 be smooth and free of irregularities (i.e., it is preferable not to have decorative grooves or other irregularities on the surface of the floor finishing material 12).

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

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

[0030] The storage finishing floor material 14 is installed as a "storage member" along the wall between the long side 16a (16b) of the installation finishing floor 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 finishing floor material 12 and smaller than twice the width W1 of the installation finishing floor 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 finishing floor material 12 and the wall surface WL (see Fig. 5). Therefore, the width W2 of the storage finishing floor material 14 needs to be set larger than the gap T between the long side 16a (16b) of the installation finishing floor material 12 and the wall surface WL.

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

[0032] The method for laying the floor finishing material set 10, configured as described above, onto the subfloor of a room will now be explained. There are two ways to lay the floor finishing material set 10: starting from the center of the room or starting from the edge of the room (near the wall). Here, we will explain the former method.

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

[0034] There are no specific rules regarding the direction in which the floor finishing materials 12 for installation and 14 for finishing are installed, but it is common practice to install them along the length of the room. Therefore, it is desirable to draw the reference line M as a line extending along the length of the room.

[0035] Next, the prepared floor finishing material 12 for installation is temporarily laid out one by one in a vertical line (in the longitudinal direction) along the reference line M (Figure 3).

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

[0037] The flooring material 12 is laid in a vertical line along the length of the room's floor surface. When the gap S in the longitudinal direction from the short side 18a (18b) of the flooring material 12 to the wall surface WL becomes shorter than the length H1 of the flooring material 12, it becomes impossible to lay any more flooring material 12. In that case, the flooring material 12 is cut to the dimensions of the gap S, and the cut piece 12P is laid into the gap S.

[0038] Once the vertical installation of the floor finishing material 12 is complete, the second row and subsequent rows are installed using the same procedure. Adjacent floor finishing materials 12 in the width direction are joined by the male tongue 20a on the long side 16a and the female tongue 20b on the long side 16b. At this time, as with the short sides 18a and 18b described above, it is preferable to leave a gap (clearance) of about 0.2 to 0.5 mm between adjacent floor finishing materials 12. In this embodiment, a so-called "fixed-length installation" method is used, where the joints of the floor finishing materials 12 are alternately offset. However, a "random installation" method, where the joint positions are offset row by row, may also be used.

[0039] Then, as shown in Figures 4 and 5, once the floor finishing material 12 is laid down until the gap T between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL is greater than the width W1 of the floor finishing material 12 and less than twice the width W1 (2W1), the finishing material 14 is then 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 floor finishing material 14 is installed as a finishing member in the gap T between the long side 16a (16b) of the final row of floor finishing material 12 and the wall surface WL.

[0041] Once the temporary arrangement of the floor finishing material 12 and the finishing material 14 is complete as described above, they are removed and fixed to the subfloor using adhesive and nails. This ensures that the entire floor surface is covered with the floor finishing material 12 and the finishing material 14. Of course, it is also possible to fix the floor finishing material 12 and the finishing material 14 directly to the subfloor without performing a temporary arrangement. In addition, a clearance of about 0.5 mm to 3 mm may be provided between the floor finishing material 12 and the finishing material 14 and the wall surface WL (between the length and width directions) to absorb expansion and contraction due to temperature and humidity.

[0042] Since the upper surfaces of the floor finishing material 12 for installation and the floor finishing material 14 for finishing have chamfers on all four sides, slight grooves 28 are formed at the boundaries between adjacent floor finishing materials 12 and between adjacent floor finishing materials 12 and floor finishing materials 14 (see Figures 6-7).

[0043] As described above, according to this embodiment, the width W2 of the finishing floor material 14 is set to be greater than the width W1 of the floor finishing material 12, and less than twice the width W1 of the floor finishing material 12. Therefore, after laying the floor finishing material 12 until the gap T between the long side 16a (16b) of the floor finishing material 12 and the wall surface WL is greater than the width W1 of the floor finishing material 12, and less than twice the length of the width W1 of the floor finishing material 12 (2W1), the finishing floor material 14 can be cut to the dimensions of the gap T and then laid as a finishing member at the wall.

[0044] Here, the floor finishing material 14 for installation can be cut to a width larger than the width W1 of the floor finishing material 12 for laying, making the cutting process easier.

[0045] Furthermore, the gap T between the long side 16a (16b) of the last row of floor finishing material 12 and the wall surface WL is larger than the width W1 of the floor finishing material 12. Therefore, sufficient working space is secured for nailing and other fastening work to fix the floor finishing material 12 to the subfloor, and work efficiency is not impaired.

[0046] Furthermore, since the width W2 of the finishing floor material 14 is wider than the width W1 of the floor finishing material 12 for installation, using it as a finishing component at the wall makes the slight deflection A of the wall surface WL less noticeable, and does not detract from the appearance after installation.

[0047] Furthermore, since the floor finishing material 12 installed in the room has a constant width W1, it can provide a neat and orderly floor surface, especially when combined with the chamfers provided around its four upper edges.

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

[0049] In this embodiment, the width W2 of the finishing floor material 14' is set to twice the width W1 of the floor finishing material 12 (2W1). This ensures that the decorative groove 30 is positioned at the same width (W1) as the floor finishing material 12, regardless of whether it is cut from the male tongue 30a side or the female tongue 30b side. Since the decorative groove 30 is formed to have the same shape as the recessed groove 28, when the floor finishing material set 10 is laid in the room, the decorative groove 30 and the recessed groove 28 blend together, resulting in a natural finish. However, if the shape of the room is irregular, or if the distance between the decorative groove 30 and the wall surface WL is short, it may result in the irregularity of the room shape or the curvature A of the wall surface WL becoming noticeable, which is undesirable.
