Description

[Detailed description of the invention] The present invention is for temporarily fixing tile units used in the pre-installation method, and relates to a sheet for pre-installation tile units that can be installed without any problem even if there are burrs on the lower side of the side. It is.

As shown in Fig. 1, the conventional sheet 1 for pre-attached tile units (hereinafter simply referred to as sheet 1) is made by heating and melting a thermoplastic synthetic resin such as polyethylene or polypropylene that exhibits adhesion to tiles during melt molding, and then hardening. The base part 2
Tiles 4, 4, ... with the back side 4b of the tiles facing upward are inserted into a large number of squares 3 for inserting tiles formed vertically and horizontally on the upper surface, and the tiles 4, 4, ... with the tile surface 4a are covered. It is for temporarily fixing. The conventional sheet 1 is melt-molded in the frame 6 using a frame 6 as shown in FIG. As shown in FIGS. 3A and 3B, in the conventional frame mold 6, the side wall inner surfaces 7, 7, . . . are formed to be flat on all four sides. The conventional sheet 1 processed using the frame 6 having such a shape is as shown in FIG.
A burr 9 is formed protruding from the lower portion 8 of the side surface. Therefore, as shown in Fig. 5, a plurality of tile units 10, 10, etc., in which the required number of tiles 4, 4, ... are temporarily fixed by the sheet 1, should be placed adjacent to each other and arranged on a wall surface, etc. However, the burr 9 comes into contact with the side surface of the adjacent tile unit sheet 1, making it impossible to bring the tile units 10, 10, ... into close contact with each other, and creating gaps between the tile units 10, 10, ... . In order to eliminate such inconveniences during construction, conventionally, the burrs 9 formed protruding from the sheet 1 have been removed in advance in the factory before the tile unit 10 is shipped. However, when shipping a large number of tile units, the number of man-hours required to remove the burrs one by one becomes enormous, and some tile units may be shipped without burrs being removed, resulting in the above-mentioned inconveniences. There is also a risk that tile unit construction will be required.

The present invention was developed in view of the above-mentioned problems, and it is possible to bring the side surfaces of a plurality of pre-attached tile units into close contact with each other without removing in advance the burrs formed protruding from the lower side surfaces of the sheet for pre-attached tile units. An object of the present invention is to provide a sheet for pre-attached tile units that can be installed in an array.

The present invention will be described in detail below based on drawings showing embodiments thereof.

As shown in FIGS. 6 and 7A and 7B, a frame 11 used for processing the pre-attached tile unit sheet according to the present invention has a peripheral wall portion 1 having four sides.
2, the inner lower portions 13' and 14' of the side wall portions 13 and 14 on at least two adjacent sides are provided with a slope 1.

a, and fills each joint space 20, 20, . A gradient 25 is formed that can absorb the amount of water inward from the side surface. here,
The two side surfaces 21', 21' refer to the tile unit 2.
It is appropriate to use the side surfaces of the outermost joint portions 27, 27 in 6. Further, as shown in FIG. 12, the gradient 25 has a height h of about 2 (mm) and a width w of about 3 (mm), which is the same as that of the frame 11. Note that the length l of the burr 24 is approximately 1 (mm).
It is of a certain degree. Therefore, the width w of the gradient 25 needs to be larger than the length l of the burr 24. Even if a plurality of sheets 19 having gradients 25 formed in this manner are used and placed adjacent to each other, the burrs 24 are absorbed by the gradients 25, as shown in FIG.

FIG. 14 is a side sectional view of a main part showing a second embodiment of the present invention. As shown in the figure, the height h of the gradient 29 may be the same as the height h ₀ of the joint portion 31 of the sheet 30. However, the width w of gradient 29 is
Of course, this length is greater than the protrusion length l of the burr 24.

FIG. 15 is a side sectional view showing a third embodiment of the present invention. The sheet 37 shown in the figure has its four sides 3
A gradient 35 that can absorb the burr 24 inward from the side surface 32 is uniformly formed near the boundary 34 between the bottom surface 33 and the bottom surface 33. In this case, the sheet 31 has half joints 36 formed around all four sides. Correspondingly, it goes without saying that gradients are also formed on the four sides of the frame (not shown).

16 to 18 show a fourth embodiment of the present invention, and FIG. 17 is a sectional view taken along line A-A' of the accessory tile unit shown in FIG.
Figure 8 is a sectional view taken along line B-B' of the same functional tile unit. As shown in the figure, gradients 42 capable of absorbing burrs 24 inward are uniformly formed on the lower side surface 39 and front section 40 of the accessory tile unit sheet 38.

As explained above in detail, according to the present invention, a gradient is formed near the boundary between at least two adjacent sides of the four side surfaces of the pre-attached tile unit sheet and the bottom surface to absorb burrs inward from the side surfaces. Therefore, pre-attached tile units using the sheet according to the present invention can be arranged in close proximity to each other without removing burrs in advance. Pre-installed tile units can be installed smoothly, improving work efficiency. Furthermore, since there is no need to remove burrs formed on sheets for pre-attached tile units in advance at the manufacturing factory, not only the production efficiency of pre-attached tile units using the sheet is improved, but also the yield rate is improved. is obtained.
