Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a tile construction method that increases the adhesive strength of tiles.

[Conventional technology] Tile construction methods include hand-laying method, pre-installation method, (frame pre-installation method, PC board pre-installation method, etc.)
Alternatively, there are various methods such as panel construction method. As is well known, irregularities called soles are formed on the back surface of the tile to increase the adhesive strength (tension strength) of the tile. One example of this uneven shape is one in which a row of protrusions with a cross-sectional shape that widens in a direction away from the back surface of the tile (herein referred to as dovetails) is provided.
Tiles with dovetail legs have higher bonding reliability because the convex portions that widen toward the ends counteract the stress that would cause the tiles to peel off.

However, in conventional tile construction methods, the bonding strength between the tile and the target surface (for example, a wall surface) is limited to the bonding strength between the back surface of the tile itself and the target surface. One possible way to obtain even greater bonding strength is to use triggers, as in the case of stone construction where stones are pasted together.
Tiles are usually thin and have a small wall thickness, so it is difficult to provide dowels or blind holes for inserting trigger objects.

Figure 2 is a diagram of the stone construction work in which the stone materials are pasted. In FIG. 2, a dowel hole 2 and a gazing hole 3 are bored in the upper end surface of a stone 1, and the tip of a trigger 4 is inserted into the gazing hole 3.
The rear end of the rod is hooked up to the reinforced steel 5. In addition, as well as stopping adjacent stones 1 with gazing 6,
Dowel pins 7 are inserted between the upper and lower stones 1 to connect them. However, as mentioned above, unlike the stone 1, the tile is a thin material with a small wall thickness, so the dowel hole 2 and the glazing hole 3 for inserting the trigger 4 are
Since it is difficult to provide such a trigger, it is difficult to adopt measures to increase bonding strength using such a trigger. Further, if the wall thickness of the tile is increased to provide dowel holes or blind holes, the tile shape will be special, and the manufacturing cost of the tile will be high.

From this point of view, the present inventor devised the construction structure shown in Figs. 1 and 3 to 6, which has a high tile attachment strength.

It is a sectional view along a line. As shown, tile 10

are provided in a row, and protrusion forming pieces 13 having a trapezoidal cross section are attached to the side slopes 12 of the protrusions 11.
is attached. Figure 4 shows this protrusion forming piece 13.
FIG. As shown in FIG. 4, the protrusion forming piece 13 has a hollow trapezoidal shape, and is fitted into the groove 14 between the protrusions 11. Note that an adhesive may be used in conjunction with this fitting.

FIG. 5 is a side view illustrating the process of attaching the tile 10 to which the protrusion forming piece 13 is attached. 15 is a concrete frame, on the surface of which base mortar 16 and pasting mortar 17 are arranged. Thus, the tile 10 is constructed by applying the affixing mortar 18 to the back surface of the tile 10 and pressing it onto the affixing mortar 17. Incidentally, as shown in the figure, the projection forming piece 13 is also filled with a pasting mortar 18. After the base mortar 16 and the pasting mortar 17, 18 have hardened, the sixth
As shown in the figure, tiles 10 are firmly bonded to concrete 19.

The present inventor also devised protrusion-forming pieces shown in FIGS. 7, 8, and 10.

FIG. 7 is a perspective view of the protrusion forming piece 20. This protrusion forming piece 20 has a slope portion 20a having a V-shaped cross section,
It has a connecting part 20b that connects the slope parts 20a and a small flange part 20c provided at the tip of the slope part 20a. These slope portions 20a and connecting portions 20
b and the flange portion 20c are integrated, and the tip of the slope portion 20a can be bent like a spring. Therefore, by pressing the slope portions 20a toward each other, the tile can be easily installed in the groove 14 on the back surface of the tile.

FIG. 8 is a perspective view of the protrusion forming piece 21. This protrusion forming piece 21 has a base part 21a and a rod-shaped part 21b erected on one surface of the base part 21a. The long side of the base portion 21a is a slope 21c that engages with the slope 12 of the tile dovetail foot. In order to attach the protrusion forming piece 21 to the tile 10, the base portion 21a may be inserted into the groove 14. When this protrusion-forming piece 21 is attached to a tile, the rod-shaped portion 21b protrudes from the back surface of the tile, increasing the bonding strength of the tiles. In addition, as shown in the figure, the rod-shaped portion 21b
has a shape that becomes thicker toward the tip side, thereby further increasing the bonding strength and reliability of the tile.

FIG. 10 is a perspective view of the protrusion forming piece 22.
2a and a roof-like curved portion 22b integral with the portion 2a. The base plate portion 22a also has a side surface formed into a slope 22c that engages with the slope 12 of the tile dovetail foot. This protrusion forming piece 22 is also pasted and constructed by filling the curved portion 22b with mortar.

A construction method similar to that shown in Figs. 1, 3 to 6 is described in Japanese Utility Model Application No. 59-8434.
For example, in Figures 13a and b of the same publication, a triangle-shaped elastic fitting with open legs is locked to the dovetail leg, and this elastic fitting is embedded in mortar to increase the tensile strength of the tile. It is shown.

[Problems to be Solved by the Invention] However, only the protrusion-forming pieces shown in Figures 1, 3 to 6, 7, 8, and 10 or the elastic fittings described in Japanese Utility Model Application Publication No. 59-8434 have been applied to tiles. When installed, if the protrusion-forming piece or elastic metal fittings separate from the mortar, the tile is no longer retained by the protrusion-forming piece or the elastic metal fittings, resulting in poor reliability.
Another problem is that the elastic fittings tend to come off the tiles.

[Means for Solving the Problems] The tile construction method of the present invention is a method of constructing tiles with dovetail feet using mortar, in which a protrusion-forming piece having a slope portion that engages with the dovetail feet is attached to the tile. A construction method in which a protrusion is formed on the back surface of the tile by being attached to the dovetail foot of the tile, a linear body is connected to the protrusion-forming piece, and the protrusion-forming piece and the linear body are buried in mortar. The forming piece has a base part and a rod-shaped part erected on one side of the base part, and the long side of the base part is a slope that engages with the slope of the tile dovetail foot. The rod-shaped portion has a shape that becomes thicker toward the tip side, and a hole is formed at the tip of the rod-shaped portion, and the linear body is passed through the hole. be.

[Function] In the present invention, since protrusions are formed on the back surface of the tile, the bonding strength of the tile is increased. In addition, even if the tiles are lifted or cracked,
Since the protrusion-forming piece supports the tile, there is no risk of the tile falling off. Furthermore, this protrusion forming piece is attached using dovetails, and is easy to attach and easy to construct.

In addition, a linear body is connected to this protrusion forming piece, and this linear body is also buried in the mortar, so
Even if the protrusion-forming piece detaches from the mortar, the tile will not fall off as long as the rod-shaped body is connected to the mortar.

In the present invention, the base portion of the protrusion forming piece fits into the dovetail of the tile, and the protrusion forming piece does not come off from the tile. Further, since the rod-shaped body protruding from the base plate has a tapered end, it is extremely difficult for the rod-shaped body to come out when buried in mortar.

[Example] Examples will be described below with reference to the drawings.

Figure 9 shows a protrusion forming piece 2 used in the example method.
1' is a perspective view of FIG. This protrusion forming piece 21' is different from the rod-shaped part 21 in the protrusion forming piece 21 shown in FIG.
A hole 21d is bored at the tip of b, and this hole 21d
A linear body 21e is connected to the wire body 21e. Similar to the construction method using the protrusion forming piece 13 shown in FIGS. 5 and 6, this protrusion forming piece 21' is latched to the dovetail of the tile 10, and the mortar 18 is applied from above to the tile. It will be constructed. In this case, the linear body 2
1e is also buried in the mortar. Since the rod-shaped body 21e has a thick tip, it becomes extremely difficult to come out when buried in mortar.

Since the linear body 21e is provided in this way, even if the rod-shaped body 21d slips out from the wall surface, the protrusion forming piece and the tile can be connected to the wall surface via this linear body 21e, and the tile can fall off. It is possible to prevent this more reliably. In addition, the 9th
In the illustrated embodiment, only one rod-shaped portion 21b is provided, but two or more rod-shaped portions 21b may be provided.

In the present invention, the material of the protrusion forming piece is as follows:
It is preferable to use a rust-free material such as stainless steel or plastic. Further, the material of the linear body 21e employed in the embodiment of FIG. 9 is preferably a material with high corrosion resistance such as copper or stainless steel.

Note that the method of the present invention can be carried out in both the hand-laying method and the tile-advancing method. Furthermore, the method of the present invention is suitable for application to construction of large tiles with a side of about 300 mm or more.
As mentioned above, the number of protrusion-forming pieces that are engaged is as follows:
The tiles are selected according to the size of the tiles, for example, in the case of a 300mm square, there are about 1 to 2 tiles, 300mm x 300mm
It is preferable to have about 4 to 6 pieces in 600 mm.

[Effects] As detailed above, according to the tile construction method of the present invention, tiles can be bonded extremely strongly. Even if the tile cracks or lifts, the bonding is maintained through the protrusion-forming piece, thereby preventing the tile from peeling off or falling off. Furthermore, since the linear body is connected to the protrusion-forming piece and this linear body is also buried in the mortar, even if the protrusion-forming piece also falls out of the mortar, the tile will pass through the linear body and the protrusion-forming piece. can be tied to the wall.

In addition, since the protrusion forming piece is attached to the tile using the dovetail legs of the tile, there is no need to provide dowel holes or blind holes in the tile, and conventional commercially available tiles can be installed. I can do it. Therefore, the protrusion forming piece is extremely easy to install and can be installed at the site.
Construction is extremely simple.

In the present invention, the bond between the protrusion forming piece and the tile is strong, and the bonding force between the protrusion forming piece and the mortar is also extremely high.
