DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1A is a side view of a base plate according to the embodiment, FIG. 1B is a longitudinal sectional view of a main part showing a tile wall using the base plate, and FIG. It is orientation explanatory drawing.
[0013]
The tile base plate 10 made of synthetic resin has a rectangular thin plate-like main body 10M. On the front surface of the main body 10M, a concave strip 11 and a tile locking portion 12 made of a convex strip extend in parallel to the horizontal direction. The concave strip 11 has an ant shape wider on the back side than the entrance. The concave strip 11 is disposed below the tile locking portion 12 by a predetermined distance.
[0014]
The upper end surface of the tile locking portion 12 is a slope 12a having an upward slope toward the front. The tile 13 is provided with a recess 14 on the back surface thereof. The upper side surface of the concave strip 14 is a slope 14a having an upward slope toward the front side of the tile 3.
[0015]
The tile 13 is hooked to the tile base plate 10 by receiving the tile locking portion 12 of the tile base plate 10 in the recess 14 and engaging the slope 14 a with the slope 12 a of the tile lock portion 12. . In order to prevent displacement of the tile 13, the bottom lower surface of the tile below the concave strip 14 is bonded to the tile base plate 10 with an elastic adhesive 15. The elastic adhesive 15 penetrates into the entire recess 11 of the tile base plate 10 and is cured.
[0016]
As shown in the figure, the space between the ant-shaped concave strip 11 and the tile locking portion 12 is such that the lower portion of the tile 13 hooked on the tile locking portion 12 covers the concave strip 11.
[0017]
In this embodiment, two ant-shaped concave ridges 11 are provided on the lower side of the tile locking portion 12, but this makes it possible to attach even the tiles having different widths of the concave ridges 14. Because.
[0018]
As the elastic adhesive 15, for example, a silicon-based elastic adhesive can be used. As the elastic adhesive, those having a tensile elongation of about 20 to 500% at normal temperature (25 ° C.) after curing are suitable.
[0019]
An L-shaped leg portion 16 and a projecting piece 17 are provided on the top of the tile base plate 10. The leg portion 16 includes a rear extending piece 16a and an upper extending piece 16b. As shown in FIG. 1B, the upper extending piece 16 b is overlapped with the trunk edge 20 and fastened to the trunk edge 20 with a screw 21. The projecting piece 17 projects upward from the rearward extending piece 16a. The protruding piece 17 is disposed slightly rearward of the front surface of the tile base plate 10 and forward of the upward extending piece 16b.
[0020]
At the bottom of the tile base plate 10, an L-shaped piece comprising a rear extending piece 18a extending rearward of the tile base plate 10 and a lower extending piece 18b extending downward from the rear extending piece 18a. 18 is provided.
[0021]
As described above, the tile base plate 10 is fastened to the trunk edge 20 with the screw 21 as described above. The lower part of the tile base plate 10 is fixed by fitting the L-shaped piece 18 with the projecting piece 17 of the tile base plate 10 disposed on the lower side.
[0022]
A support piece 19 is erected on the back surface of the tile base plate 10. The tip of the support piece 19 comes into contact with the trunk edge 20 when the tile base plate 10 is attached to the trunk edge 20.
[0023]
After fixing the tile base plate 10 to the wall edge 20 of the wall in this way, the elastic adhesive 15 is filled into the concave strip 11 of the tile base plate 10, and at this time, the elastic adhesive 15 passes from the concave strip 11 to the bottom of the tile. Raise to the front side of the main plate. Thereafter, the concave strip 14 of the tile 13 is hooked on the tile locking portion 12, and the lower back surface of the tile 13 is pressed against the front surface of the tile base plate 10. A tile wall is constructed by sticking the tiles 13 sequentially in this manner from the lower side.
[0024]
In this embodiment, the tiles 13 are combined, and the upper edge of the lower tile engages with the lower edge of the upper tile. The upper end surface of the lower tile and the lower end surface of the upper tile may be separated from each other with a predetermined joint interval.
[0025]
In this tile wall, since the tile base plate 10 is made of a synthetic resin, the adhesive force of the elastic adhesive 15 to the tile base plate 10 is low. For this reason, as shown in FIG. 1B, by pulling the lower part of the tile 13, the elastic adhesive 15 can be peeled off from the tile base plate 10, and the tile 13 can be detached from the tile base plate 10. Thereby, tiles can be replaced. In addition, the tile can be partially repaired. The separated tiles can be reused as ceramic materials.
[0026]
The tile base plate 10 from which the tiles 13 are removed may be attached with another tile as described above, or may be removed from the trunk edge 20 and reused. The tile base plate 10 that has become unnecessary may be used as a raw material for producing a new tile base plate 10. For example, the tile base plate can be crushed and used for manufacturing a new tile base plate.
[0027]
In this tile wall, the adhesive force of the elastic adhesive 15 to the tile base plate 10 is low, but the elastic adhesive 15 is filled in the ant-shaped recess 11 of the tile base plate 10. Even if a load of an earthquake level is applied to the tile 13, the tile 13 does not peel off from the tile base plate 10.
[0028]
Below, the constituent material of this tile baseplate 10 is demonstrated in detail.
[0029]
The tile base plate 10 is made of a synthetic resin molded product including reinforcing fibers such as glass fibers and needle-like minerals. In this embodiment, the reinforcing fiber is a glass fiber 1 having an average length of about 0.1 to 30 mm. Since a part of the glass fiber 1 continuously extends from the main body 10M to the locking part 12 as shown in FIG. 1 (c), the locking part 12 has a sufficiently high strength and a heavy tile. Even so, it can be held firmly for a long time. Moreover, since the strength reduction of the locking part due to heat due to fire or the like is suppressed, the flame retardancy of the tile wall is also improved.
[0030]
In this embodiment, since a part of the glass fiber extends continuously from the main body 10M to the support piece 19, the strength of the support piece 19 is also high.
[0031]
The tile base plate 10 may be obtained by melting and extruding a crushed material of thermoplastic synthetic resin product waste. Moreover, even if the crushed material of the thermosetting synthetic resin product waste and the crushed material of the thermoplastic synthetic resin product waste are mixed and heated, the thermoplastic synthetic resin is melted and molded by extrusion molding. Good. This extrusion direction is the extending direction of the concave strip 11 and the tile locking portion 12.
[0032]
Thermosetting synthetic resin products include, for example, engineering plastics (polyamide, polyacetal, polycarbonate, modified PPE, polyester, etc.) used in FRP bathtubs and automobile parts, decorative plates such as melamine resins, phenol resins, urea resins, FRP ships, Examples include automobile parts FRP, FRP bathroom (floor, ceiling, wall), FRP septic tank, helmet FRP, polyurethane heat insulating material, printed tile base plate epoxy, silicone resin, and the like. This FRP bathtub is composed of glass fiber and an unsaturated polyester resin containing a filler such as aluminum hydroxide or calcium carbonate. The FRP bathtub is crushed to a particle size of 5 mm or less, for example, an average particle size of about 2 to 3.5 mm and reused. The FRP bathtub crushed material contains glass fiber, and this glass fiber can be used as it is as a reinforcing fiber. Aluminum hydroxide or calcium carbonate in the FRP crushed material is thermally decomposed and absorbs heat when subjected to fire heat, thus increasing the flame retardancy of the tile base plate.
[0033]
Thermoplastic synthetic resin products include toilet seats and household appliances made mainly of polypropylene, packaging films made mainly of polyethylene, various containers, tupperware, containers, buckets, and kitchen utensils made mainly of polystyrene. Sanitary goods, stationery, etc. are exemplified. The thermoplastic synthetic resin product is crushed to 25 mm or less, for example, an average particle diameter of about 2 to 10 mm, and mixed with a crushed product of the thermosetting synthetic resin product. This mixing may be performed in advance or in a mixer. As this mixer, a screw having an internal screw and melting a thermoplastic synthetic resin by frictional heat during mixing to produce a plastic composition is preferable. A method may be used in which the thermoplastic synthetic resin is previously melted by external heating or mixed with the thermosetting synthetic resin while being melted. A tile base plate is produced by extrusion molding or injection molding the plastic composition. The mixing ratio of the thermosetting synthetic resin product and the thermoplastic synthetic resin product is not particularly limited, but is about 30 to 400 parts by weight of the thermoplastic synthetic resin product with respect to 100 parts by weight of the thermosetting synthetic resin product. If it exists, a tile baseplate can be manufactured efficiently.
[0034]
In addition, you may add a new resin raw material and glass fiber with respect to a waste material. Needle-like minerals such as sepiolite and zonotolite may be used instead of or together with glass fiber.
