DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile made of concrete or the like, which is used for decoration and is installed on a waterproofed roof.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional heat insulating tile already proposed in Japanese Utility Model Laid-Open Publication No. 4-51514. The tile body has a downward front connecting portion 11 and an upward rear connecting portion 12, and is substantially Z-shaped. It is shaped like a letter. In order to lay the heat-insulating tile, the front connection part 11 of the next tile under the eaves is covered on the rear connection part 12 of the heat-insulating tile placed near the purlin, and so on. I will do it.

[0003] In this heat insulating tile, a cavity 13 is provided as shown in the figure.
Because the door is open, it can block the heat conduction of direct sunlight in the middle of summer, radiates heat by ventilation, and also has the effect of suppressing sound from above.

[0004]

However, the heat insulating tile having such a structure has the following disadvantages.

(1) Since the shape of the roof tile for heat insulation is too complicated, it is difficult to make a mold for an extrusion machine, and it is necessary to carefully extrude at a low speed when performing extrusion molding.
It takes time to mold.

(2) Since the shape of the roof tile for heat insulation is too complicated, it takes time to fit the front connecting portion 11 with the rear connecting portion 12 at the time of laying.

(3) Since the insulating tiles are simply placed on a concrete roof or the like, if they are peeled off in a strong wind, or if they are fixed by mortar or the like, they are insufficiently fixed by the mortar. When it was over time, the fixing force was lowered due to the deterioration over time, and it was sometimes peeled off and blown off by a strong wind.

[0008] The technical problem of the present invention is to focus on such a problem, and to provide an insulated tile that can be easily laid without complicating the shape and that can be laid firmly without peeling off due to a strong wind. Is to make it happen.

[0009]

According to a first aspect of the present invention, as shown in FIG. 1, in a tile fixed on a mortar, the tile is parallel to a bottom surface of the tile K in a direction perpendicular to the inclination direction of the roof. At least three fixing legs 1a, 1b, and 1c are projected, and each of the fixing legs is arranged such that the lower surface of the intermediate fixing leg 1b is higher than the surface including the lower surfaces of the upper and lower two fixing legs 1c and 1a. The heat-insulating tile is provided with the height of the legs and the side surface of at least one fixing leg formed so as to become wider toward the lower end, so that the legs have a flared shape.

According to a second aspect of the present invention, as shown in FIG. 2, one or a plurality of fixing legs 2 are protruded from the bottom surface of a tile K to be mounted on a mortar and fixed. The heat-insulating tile is provided with an inverted trapezoidal groove 4 that is wider at the lower end of the leg 2.

According to a third aspect of the present invention, as shown in FIG. 3, one or a plurality of fixing legs 3 are projected from the bottom surface of a tile K to be mounted on a mortar and fixed. The side surface of the leg 3 is formed so as to be wider toward the lower end, so as to form a flared leg. In addition, the lower end of the fixing leg 3 has an inverted trapezoidal groove 4 which is wider toward the upper side. is there.

According to a fourth aspect of the present invention, as shown in FIGS. 3 and 4, in the heat insulating tile according to any one of the first to third aspects, one or a plurality of cavities 5 are provided in the tile K. Have
This cavity 5 is a heat-insulating tile penetrating in a direction perpendicular to the inclination direction of the tile upper surface.

[0013]

[0014]

According to the present invention, the roof K protrudes from the bottom surface.
Since at least one of the at least three fixing legs 1a, 1b, and 1c is spread in a mortice shape, when the insulating tile of the present invention is placed on the mortar and pressed, the mortar is spread out. It wraps around the side surface of the leg 1 and is dried and solidified while biting. As a result, the flared legs 1 are less likely to be detached from the mortar, and the heat-insulating tiles are not separated from the mortar even in a strong wind, so that the fixing to the mortar becomes strong.

In particular, the two fixing legs 1c, 1
Since the height of the fixing leg 1b is set so that the lower surface of the intermediate fixing leg 1b is higher than the surface including the lower surface of FIG. a, the intermediate fixing leg 1b does not reach the roof surface. The space between the fixing legs 1c and 1a on both sides becomes large, and a sufficient amount of mortar can be filled. Also, an intermediate fixing leg 1b
Does not reach the roof surface, so the lower surface and both side surfaces
The surface comes into contact with the mortar, and the bite with the mortar becomes more reliable.

In a case where the lower end of the fixing leg 2 protruding from the bottom surface of the heat insulating tile K is provided with a dovetail-shaped groove 4 which is wider toward the upper side as described above, it is placed on a mortar and pressed. Since the mortar bites into the dovetail-shaped groove 4 and is dried and solidified, the heat-insulating tile does not separate from the mortar even in a strong wind.

According to the third aspect, the outer shape of the fixing leg 3 is flared as in the first aspect, and the dovetail-shaped groove 4 is provided as in the second aspect. Leg 3
When the mortar is pressed against the mortar, the mortar wraps around the side surface of the flared leg 3 to be dried and solidified, and also digs into the dovetail-shaped groove 4 to be dried and solidified.

As a result, the fixing action on the outer surface of the fixing leg 3 and the fixing action by the dovetail-shaped groove 4 are combined, so that the fixing to the mortar becomes stronger, and the detachment of the heat-insulating tile in the event of a typhoon or a storm is more prevented. Be certain.

By providing the cavity 5 in the heat insulating tile K having a strong bonding force with the mortar, the heat conduction between the upper surface and the lower surface of the heat insulating tile is cut off by the cavity 5, and Since the wind passes through the cavity 5 and heat radiation is effectively promoted, the heat can be efficiently insulated even when receiving strong direct sunlight, and the transmission of noise from the sky is also suppressed.

EXAMPLES Next, practical examples of how a heat insulating tile according to the present invention is embodied will be described with reference to examples. FIG.
In this example, the fixing legs 1a, 1b, and 1c arranged in parallel with each other at three places on the bottom surface of the tile K are perpendicular to the inclination of the surface of the tile. That is, it is formed in a rail shape in the horizontal direction.

The fixing legs 1a, 1b, 1
As for c, the side face is wider toward the lower end, and has a flared shape. Therefore, when the heat insulating tile K of the present invention is placed on the mortar applied to the roof surface Y and pressed and shaken in the horizontal direction, the mortar is initially placed in the depression 9 between the fixing feet 1a, 1b, and 1c. Moves in the direction of arrow a1, but when it hits the lower surface of the roof tile body, it then moves in the direction of arrow a2, and the mortar spreads to the base of the flared legs. As a result, the mortar is dried and solidified in a state in which the mortar bites into the side surfaces of the fixing legs 1a, 1b, and 1c, and the heat insulating tile K is firmly fixed to the mortar.

The fixing legs 1a and 1c on both sides are molded to a height such that their bottom surfaces are located on the same plane, are laid on mortar applied to the top surface of the roof, and the roof tile K is placed on the mortar. Pressing and rocking back and forth, left and right, both fixing legs 1a,
The lower end of 1c bites into the mortar.

The fixing legs 1a and 1c on both sides of the tile K are almost in contact with the upper surface Y of the roof, while the fixing legs 1b at the center are
The height h2 does not reach the roof surface Y. As a result, the fixing leg 1a on the underside of the eave and the fixing leg 1c on the purlin side are
And a sufficient amount of mortar can enter, and the fixing legs 1a and 1c on both sides can sufficiently penetrate into the mortar.

Further, since the intermediate fixing leg 1b does not reach the roof surface, the lower surface and the three side surfaces on both sides are in contact with the mortar, and the biting with the mortar is further ensured.

In the figure, the roof tile K is shown in such a manner that the underside of the roof tile K shown by the solid line overlaps the front end of the roof tile K below the eaves indicated by the chain line.
The height h3 of the front end is the height h4 of the fixing leg 1a below the eaves.
It is the same or slightly lower. Therefore, the height of the fixing leg 1c closer to the purlin is lower than the height h4 of the fixing leg 1a closer to the eaves, and when the tile is placed on a horizontal plane, the roof surface of the roof tile has a higher slope at the lower side of the eaves.

Further, the fixing leg 1c on the upper end side (close to the purlin)
Although the amount of penetration into the mortar is shallow, the amount of penetration into the mortar of the fixing leg 1a at the lower end side (under the eaves) is large. The connection structure with the mortar is different between the case where the bite amount is shallow and the case where the bite amount is deep, and it has advantages and disadvantages. However, since both are employed in one heat insulating tile, the fixing to the roof is ensured.

Incidentally, it is also possible to make only some of the fixing legs 1a, 1b, 1c have a flared shape.

FIG. 2 shows an embodiment of the second aspect of the present invention.
At the lower ends of the fixing legs 2a, 2b, 2c protruding from the lower surface of the tile, inverted trapezoidal grooves 4 which are wider toward the upper side are provided. In the illustrated example, the outside of the fixing leg 2 of the roof tile K is vertical, but may be in a flared shape as shown in FIG.

When the roof tile K of the illustrated example is placed on a mortar and is swung back and forth and left and right while being pressed in the same manner as described above, the mortar bites into the dovetail-shaped groove 4. When the mortar solidifies, the mortar that cuts into the groove 4 causes the tile K
Therefore, it is possible to reliably prevent the tile K from peeling off.
Note that a configuration in which the dovetail groove 4 is provided only in some of the fixing legs 2a, 2b, and 2c is also possible.

FIG. 3 shows an embodiment of the roof tile according to the third aspect. The embodiment shown in FIG. 1 and FIG.
Has a divergent shape, and a dovetail-shaped groove 4 is provided on the bottom surface thereof. Therefore, the mortar bites into the flared outer surface of the fixing leg 3 so as to wrap it from the outside, and also bites into the dovetail-shaped groove 4 to capture and fix the fixing leg 3 of the insulating tile from both the inside and the outside. .

It is to be noted that all of the fixing legs 3a, 3b, 3c are not divergent and dovetail grooves 4 are provided, but some legs are divergent and other legs are divergent. Instead, a shape in which the dovetail groove 4 is provided is also possible.

Further, as shown in claim 4, the main body of the roof tile K is provided with a cavity 5 penetrating in a direction perpendicular to the inclination direction of the upper surface of the roof tile, that is, in a horizontal direction. Therefore, heat due to direct sunlight can be cut off by the cavity 5, and heat trapped in the cavity 5 is released by the wind passing through the cavity 5,
It is possible to suppress the rise in temperature inside the house in summer. In addition,
When laying on the mortar as shown in FIG. 4, a gap of about 5 mm is provided between adjacent tiles in the direction in which the cavity 5 penetrates, so that ventilation is improved and heat radiation efficiency is improved.

In addition, the cavity 5 also suppresses the propagation of sound from the sky, and thus has a soundproofing effect. In addition, the provision of the cavity 5 makes the roof tile K lighter, reduces the burden on the worker, and secures the strength by the intermediate support portion 6.

FIG. 4 is a cross-sectional view taken along the line AA of FIG. 3 in which the roof tile K of FIG. 3 is laid on a mortar. The roof tile K is placed on a mortar M applied on a concrete roof Y and pressed.
Rocking back and forth and left and right so that
The mortar M enters between the fixing leg 3 and the bottom of the tile body, and the mortar also enters the dovetail groove 4 on the lower surface of the fixing leg.

That is, the mortar spreads to the depression 9 between the fixing legs 1a, 1b, and 1c and the depth in the dovetail-shaped groove 4. As a result, after the mortar M is dried, the mortar M is fixed from both the outside and the inside of the fixing leg 3, and there is no possibility that the mortar M will be peeled off even in a strong strong wind or a storm.

As is apparent from FIG. 4, the roof tiles K vary depending on the thickness of the mortar M applied to the upper surface of the concrete roof Y.
Of the fixing roof 3 touches the upper surface of the concrete roof Y or floats on the mortar M as shown in the figure, but the mortar is in the dovetail groove 4 or the fixing feet 1a, 1b,
It is necessary to have a sufficient amount of mortar enough to reach into the depression 9 between 1c.

[0038]

According to the first aspect, since the fixing leg 1 protrudes from the bottom surface of the tile K and extends in a tenon shape, the heat insulating tile of the present invention is placed on the mortar and pressed. The mortar wraps around the side surface of the flared leg 1 and is dried and solidified in the biting state. As a result, the flared legs 1
The bond between the mortar and the mortar becomes strong, so that the insulating tile does not separate from the mortar even in a strong wind, and there is no danger that the tile will be peeled off by the strong wind and fly, causing damage or injury to people.

In particular, the two fixing legs 1c, 1
Since the height of the fixing leg 1b is set so that the lower surface of the intermediate fixing leg 1b is higher than the surface including the lower surface of FIG. a, the intermediate fixing leg 1b does not reach the roof surface. The space between the fixing legs 1c and 1a on both sides becomes large, and a sufficient amount of mortar can be filled. Also, an intermediate fixing leg 1b
Does not reach the roof surface, so the lower surface and both side surfaces
The surface comes into contact with the mortar, and the bite with the mortar becomes more reliable.

Even when the dovetail-shaped groove 4 is provided at the lower end of the fixing leg 2 protruding from the bottom surface of the heat-insulating tile K, if the mortar is placed on and pressed against the mortar, the mortar becomes dovetail groove. Since the mortar and the mortar-shaped groove 4 are solidified by being cut into the groove 4 and dried and solidified, there is no possibility that the heat-insulating tile is detached from the mortar even in a strong wind.

According to the third aspect, the outer shape of the fixing leg 3 is flared as in the first aspect, and the dovetail groove 4 is provided as in the second aspect. When pressed against the mortar, the fixing action by the flared shape of the fixing leg 3 and the fixing action by the dovetail groove 4 are combined.
The fixation to the mortar becomes stronger, and the detachment prevention of the heat-insulating tile in the event of a typhoon or a storm becomes more reliable.

According to a fourth aspect of the present invention, a cavity 5 is provided in the heat-insulating tile K having a strong bonding force with mortar to suppress heat conduction.
By ventilating the cavity 5, even if it receives strong direct sunlight, it can be efficiently insulated, and in addition, transmission of noise from the sky is suppressed, and a soundproof effect can be obtained.

[0043]

Further, as an effect common to the first to fourth aspects, since the shape of the heat insulating tile is simple, molding is easy, and the shape of the mold is simple and can be manufactured at low cost. In addition, since it is sufficient to simply place the tiles on the mortar, it is possible to solve the problem that it takes time to align adjacent tiles as in the related art, and to improve the workability at the time of laying.
