Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a baseboard attached to a joint between a wall and a floor and a decorative panel serving as a wall finishing material. [Background technology]

[0002] In the construction of buildings, facilities such as food factories where drainage must be taken into consideration require sloping floors. In addition to food factories, other such facilities include semi-outdoor underground parking lots, fish markets, clean rooms, medical institutions, etc. In addition, when painting the floor, it is possible that the amount of paint used may result in an uneven surface (roughness).

[0003] On the other hand, baseboards are installed where the wall meets the floor to prevent water from seeping into the wall's base material, protect the wall surface, and improve the appearance. Water seepage can lead to mold growth and a deterioration of the sanitary environment, so preventing water seepage is extremely important. Furthermore, if decorative panels are attached to the wall using the top end of a baseboard that has been installed while the floor is sloped or uneven as a reference point, adjacent decorative panels may interfere with each other, gaps may occur, or the top ends of adjacent decorative panels may not be aligned, slowing down the progress of construction. In addition, it is difficult to treat the upper end of the baseboard and the lower end of the decorative panel, which not only detracts from the aesthetic appearance but also may allow water to seep in through the boundaries.

[0004] In view of the above situation, Patent Document 1 discloses a baseboard that is fixed integrally to the underside of the baseboard body and has an elastic member that can be compressed and deformed in the vertical direction when the baseboard is installed, thereby eliminating unevenness in the floor surface and preventing gaps from occurring between the baseboard and the floor. Patent Document 1 also describes that the baseboard disclosed has a notch at the top end into which the bottom end of the wall material is fitted. [Prior art documents] [Patent documents]

[0013] (About baseboards) Fig. 1 is a perspective view of a baseboard 1 in this embodiment, attached to the joint between a wall W and a floor F, Fig. 2 is a cross-sectional view of the baseboard 1, and Fig. 3 is a perspective view from the rear side. Baseboards are components that serve to prevent water from entering the joint between the wall and floor, maintain aesthetic beauty, and protect the wall surface from physical collisions.

[0014] The main components of the material are cement, silicate powder, aggregate, and fiber, and the material is non-combustible. First, the manufacturing process and material will be described in detail.

[0015] (Baseboard manufacturing method) The manufacturing process involves mixing the above ingredients in the appropriate ratio (mixing process), adding an appropriate amount of water, and kneading again (kneading process). The kneaded mixture is fed into an extrusion molding machine and extruded to obtain an extruded molded body, which is the baseboard 1 (extrusion molding process). The resulting extruded molded body, which is the baseboard 1, is then cured and dried (curing and drying process) to complete the product. By using a solid structure rather than a hollow structure, the accumulation of fine dust and the occurrence of condensation due to temperature differences are suppressed.

[0016] The baseboard 1 obtained by the above manufacturing method is excellent in heat resistance, impact resistance, frost resistance, and water resistance, and is suitable as a non-combustible material. Specifically, the strength attenuation rate is 10% or less, and the thermal expansion coefficient is 1.0 to 15.0 × 10 -6 / ℃, impact strength 0.8~25.0kJ / m 2 It is also preferable that the thermal conductivity is 0.3 W / mK or less and the water absorption is 40% or less. Furthermore, if the baseboard 1 is immersed in water and repeatedly frozen and thawed, it is preferable that the volume change rate be 10% or less, since this provides excellent water resistance and frost damage resistance.

[0017] (About the appearance characteristics of baseboards) In this embodiment, the baseboard 1 is long in the Z direction in Figure 1 and is composed of a back portion 11 that abuts against the wall W as shown in Figure 2, a front portion 12 that has a curved shape when viewed in cross section and faces the inside of the room, a bottom portion 13 that abuts against the floor surface F and connects the back portion 11 (lower end) and the front portion 12 (lower end), and an upper end portion 14 that connects the upper end of the back portion 11 and the upper end of the front portion 12.

[0018] Furthermore, when the baseboard 1 of this embodiment is examined in detail, a notch 15 is formed on the wall portion 11 side of the upper end 14 of the baseboard 1, cut out at approximately a right angle when viewed in cross section, connecting the upper end of the wall portion 11 to the upper end of the front portion 12, and a chamfered portion 16 with rounded corners is formed at the connection between the lower end of the back portion 11 and the bottom portion 13. The function and effect of the chamfered portion 16 will be explained in detail later in connection with the method of attaching the baseboard and the wall finishing material.

[0019] FIG. 4 is an enlarged cross-sectional view and an enlarged perspective view of the notched portion 15 (upper end portion 14) of the baseboard 1. As shown in Figure 4(a), the notch portion 15 is composed of a notch portion bottom surface 15a and a notch portion wall surface 15b, and the notch portion bottom surface 15a is formed approximately horizontally at a position P lower than the upper end height T of the upper end portion 14 (baseboard 1), and the notch portion wall surface 15b is formed approximately vertically on the front portion 12 side V rather than the same plane position B of the back portion 11. In this embodiment, the height position P of the bottom surface 15a of the notch is set at a position approximately 7 mm lower than the upper end height T of the baseboard 1, and the position V of the wall surface 15b of the notch is set approximately 7 mm closer to the front of the baseboard 1 than the flush position B of the back portion 11. However, the height position P of the bottom surface 15a of the notch portion may be set lower than the upper end position of the baseboard 1 to accommodate the slope or unevenness of the floor F, and for example, a position 3 mm to 10 mm lower than the upper end position of the baseboard 1 is preferable. The position V of the recessed portion wall surface 15b may also be set at a position closer to the front of the baseboard 1 than the flush position B of the back portion 11, taking into account the thickness of the wall finishing material 2 to be accommodated and the caulking agent C to be filled; for example, a position 3 mm to 10 mm closer to the front of the baseboard 1 than the flush position B of the back portion 11 is preferable.

[0020] FIG. 5 is a diagram showing the mounting structure of the baseboard 1 and the wall finishing material 2 in this embodiment. In this embodiment, a wall W is constructed by arranging gypsum boards S on either side of a base material U, LGS (lightweight steel frame), which is erected from a floor surface F, and baseboards 1 and wall 2 finishing materials 2 are adhered to the surface side. It also shows that the connection parts between floor F and baseboard 1, wall W and baseboard 1, and baseboard 1 and wall finishing material 2 have been treated with caulking agent C to improve water resistance and airtightness. Here, the wall is not limited to one made of LGS and gypsum board, and can be selected appropriately depending on the construction situation. Furthermore, the material of the floor F is not particularly limited, and may be selected appropriately from general materials that are expected to be used in facilities where the use of water and chemicals is expected.

[0021] (About wall finishing materials) In this embodiment, a non-flammable, rectangular, decorative calcium silicate board with a thickness of approximately 6 mm is used as the wall finishing material 2. The decorative calcium silicate board has antiviral and antibacterial properties due to the polyester resin coating on the calcium silicate board, and is suitable for use on the walls of food factories, semi-outdoor underground parking lots, fish markets, clean rooms, medical institutions, etc. In addition, known wall finishing materials such as kitchen panels, etc., can be selected appropriately according to the facility, in addition to decorative calcium silicate boards.

[0022] (How to install baseboards and wall finishing materials) Floors that take drainage into consideration may have a slope, or unevenness may occur during the floor construction stage. If, as in the past, a baseboard 1 is first placed where the wall W and floor F meet, and then wall finishing material 2 is attached using the top of the baseboard 1 as a reference, the wall finishing material will tilt relative to the horizontal line in response to the slope or unevenness of the floor, causing problems such as gaps and interference between the wall finishing materials. Figure 6 is a schematic diagram showing the state in which wall finishing material 2 is installed based on the upper end of baseboard 1. In Figure 6(a), the wall finishing material 2 is tilted relative to the horizontal line due to the slope of floor F, and in Figure 6(b), the wall finishing material 2 is installed horizontally based on the upper end of baseboard 1, and a gap has occurred between baseboard 1 and wall finishing material 2 due to the slope of floor F. In the past, in order to solve this problem, it was necessary to perform additional work such as cutting and grinding the edges of the wall finishing material 2 so that it could be installed horizontally at the time of installation.

[0023] Example 1 (Wall finishing material pre-attaching method) Therefore, in Example 1 of this embodiment, first, as shown in Fig. 7, a horizontal reference line L is drawn on the gypsum board S between the height T of the top of the baseboard 1 from the floor surface F and the height P of the bottom surface 15a of the notch. In other words, the relationship of height positions from the floor surface is height P of the bottom surface of the notch < reference line L < height T of the top of the baseboard. As shown in Fig. 8, wall finishing material 2 is attached to the gypsum board S so that the bottom end of the wall finishing material 2 is aligned with reference line L, and caulking agent C is applied to the bottom end of the wall finishing material 2 as shown in Fig. 9.

[0024] Then, as shown in FIG. 10, the baseboard 1 of this embodiment is placed at the joint between the gypsum board S (wall W) and the floor F, and the caulking agent C is again applied near the notched portion 15. As described above, applying caulking agent C to the lower end of the wall finishing material 2 near the step notch 15, placing the baseboard 1, and then applying more caulking agent C is effective in preventing water from entering the gypsum board S side of the wall and improving airtightness.

[0025] Here, as shown in Figure 11, the lower end of the wall finishing material 2 attached to the gypsum board S is brought close to the step notch 15 of the baseboard 1, and then the back part 11 of the baseboard 1 is abutted against the gypsum board S, and the bottom part 13 is abutted against the floor F. When the baseboard 1 is installed in this manner, the notch 15 can serve to position the baseboard 1 relative to the wall finishing material 2 (bottom end), and the chamfered portion 16 formed at the connection between the back portion 11 and the bottom portion 13 of the baseboard 1 can be filled with caulking agent C to allow the baseboard 1 to be positioned without being affected by unevenness in the floor F, and can also serve to prevent interference with the floor F (compare Figures 12(a) and (b)).

[0026] By adopting this wall finishing material pre-attaching construction method, the installation structure of the installed baseboard 1 and wall finishing material 2 (see Figure 13) is as follows: The wall finishing material 2 is attached horizontally to the gypsum board S before the baseboard 1 is installed, so the attachment of the wall finishing material 2 is not affected by the slope or unevenness of the floor. The installation structure allows the lower end of the wall finishing material 2 to fit into the notched portion 15 of the baseboard 1, improving the aesthetic appearance. After the wall finishing material 2 is attached to the gypsum board S, the caulking agent C is applied twice with a time interval between each application, once after the baseboard 1 is installed, thereby improving water-resistance and airtightness. The following effects can be expected.

[0027] Example 2 (Baseboard pre-attachment method) In Example 2 of this embodiment, first, the baseboard 1 is attached to the joint between the wall W and the floor F. At this time, the baseboard 1 is attached in a state where it is affected by the slope and unevenness of the floor F. Figure 14(a) shows that the baseboard 1 is installed with the floor tilted at about 1 degree from right to left, and Figure 14(b) is a perspective view showing that the notched portion 15 and chamfered portion 16 of the baseboard 1 are filled with caulking agent C.

[0028] Next, the lower end of the wall finishing material 2 is inserted into the notch 15 of the baseboard 1, and the wall finishing material 2 is pressed against the gypsum board S so that it is horizontal (FIG. 15). In this case, in order to attach the wall finishing material 2 horizontally, a known technique for attaching the wall finishing material 2 horizontally to the gypsum board S can be adopted, such as drawing a horizontal reference line on the surface of the gypsum board S in advance, and this can be selected appropriately by a person skilled in the art. FIG. 16 shows the state in which the wall finishing material 2 is attached without being affected by the slope or unevenness of the floor F. Then, the notch 15 of the baseboard 1 into which the lower end of the wall finishing material 2 is inserted is caulked again.

[0029] In this way, by adopting the baseboard pre-attaching method, The wall finishing material 2 is attached horizontally to the gypsum board S before the baseboard 1 is installed, so the attachment of the wall finishing material 2 is not affected by the slope or unevenness of the floor. The installation structure allows the lower end of the wall finishing material 2 to fit into the notched portion 15 of the baseboard 1, improving the aesthetic appearance. After the wall finishing material 2 is attached to the gypsum board S, the caulking agent C is applied twice with a time interval between each application, once after the baseboard 1 is installed, thereby improving water-resistance and airtightness. The following effects can be expected. [Explanation of symbols]
