Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial field of application The present invention is a flat roof tile that can be erected on the roof surface. The present invention also relates to a flat roof tile that reliably keeps the state of connection with the roof underlaying material on the roof surface and is light in weight.

Conventional technology Conventionally, when roofing flat roof tiles on the roof, plaster, mortar, and other roof base materials have been attached to the base plate, and then flat roof tiles have been overlaid on the roof base materials. Since the shape of the back surface of the roof tile is flat, the binding force between the roof base material and the flat roof tile is extremely weak, and the roof base material and the flat roof tile are separated by the force of the vibration during an earthquake or the wind during strong wind. There is a risk of scattering, dropping, etc., and although a protrusion is provided on the back surface to avoid such a risk, the increase in weight does not only meet the need for weight reduction. However, since the weight of the roof is increased, a burden is placed on the base material and the structural material, which causes various problems such as an increase in construction cost.

In addition, since the conventional snow roof tiles are used for a part of the roof tiles, the snow load may be partially concentrated and the snow roof tiles may be damaged, which in turn adds to the building itself due to an unbalanced load. It has a drawback that the tile roof is damaged because the burden becomes significant.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention aims to reduce the weight by engraving innumerable recesses on the front and back surfaces of the roof tile body, and prevents the strength from being reduced by the honeycomb-shaped ribs, and further improves the roof substrate. The roof and the roof tiles are firmly fixed to each other by the material and the recesses to prevent the roof base material and the roof tiles from being separated from each other due to the vibration of the earthquake or the wind force at the time of strong wind, and to provide the snow roofed roof tiles. .

[Constitution of device]

[Means for Solving the Problems] In view of the above point, the present invention has a honeycomb shape with a large number of concave portions that are formed in a hexagonal shape in plan view on the front surface and the back surface of a flat tile roof body or a combination thereof. The above drawbacks are not solved by providing a flat roof tile having ribs.

Effects In the present invention, by stacking the roof tile material on the roof substrate such as plaster or mortar placed on the roof surface,
The roof base material enters into the recess on the back surface of the roof tile body so that the recess and the roof base material can be fitted into each other in an uneven shape, and the recess on the surface can prevent snow, and the recess can reduce the weight. To give.

In addition, the honeycomb-shaped rib reinforces the roof tile body and controls drying shrinkage and firing shrinkage. An embodiment of the present invention will be described below with reference to the drawings. Yes, on the back surface 2 of the roof tile body 1,
It is formed in a hexagonal shape in a plan view, and is formed with a large number of concave portions 3, 3a ... Engraved at a predetermined depth so as to be reduced as it goes downward, to form a continuous honeycomb-shaped 4, 4a. There is.

The depth of the recesses 3, 3a ... May be set to any depth that does not affect the strength of the roof tile body 1.

5 is a superposed section, and the superposed section 5 is provided on one side of the roof tile body 1.
In addition to extending from the surface 6 in the form of a paragraph, a ridge 7 for guiding rainwater in the flow direction is provided on the side edge.

8 is a superposed section, and the superposed section 8 is on the other side of the roof tile body 1,
When the protrusions 9 are formed inwardly on the side edge side so that the protrusions 7 can be fitted into each other in a paragraph shape from the back surface 2, and the protrusions 9 are overlapped with the overlapping portion 5 to face each other, The adjacent roof tile main bodies 1 are formed so as to be formed in the same plane.

In the figure, 10 and 10a are nail holes.

Next, another embodiment will be described. As shown in FIG. 2, the depths of the recesses 3, 3a ... Make the central portion 11 of the roof tile body 1 shallow and at appropriate intervals in the width direction of the roof tile body 1. If possible, extend along the length of the roof tile body 1 to form the concave portion 3,
It is formed so that the depth of 3a ... can be made shallow to form the projected ridges 12, 12a.

Further, in other embodiments, the recesses 3 and 3a similar to the above are provided.
A continuous honeycomb-shaped rib 4, 4a, which is composed of ...
Is formed.

Furthermore, in another embodiment, the honeycomb-shaped continuous ribs 4, 4a ... Are formed on the front surface 6 and the back surface 2 by the recesses 3, 3a.

Next, the operation of the flat roof tile according to the present invention will be described. A roof base material such as plaster or mortar placed on the roof surface 13
By stacking the roof tile main body 1 on the roof tile body 1, the roof base material 13 is inserted into the recesses 3, 3a ...
3a ... and the roof base material 13 can be fitted in a concavo-convex shape, and the recesses 3, 3a on the surface 6 can prevent snow, and the recesses 3, 3a ... When a part of the wind blown up on the surface 6 enters the concave portions 3, 3a, the collision surface is a flat surface, so that the resistance is large and the flow velocity of the wind is effectively attenuated. Change randomly.

Further, the honeycomb-shaped ribs 4, 4a ... Reinforce the roof tile body 1 and control drying shrinkage and firing shrinkage.

[Effect of device]

In short, according to the present invention, the front surface 6 and the back surface 2 of the flat-plate roof tile body 1 are formed in a hexagonal shape in plan view, and the honeycomb-shaped ribs 4, 4a ... Are formed by the plurality of recesses 3, 3a ... By stacking the roof tile base material 1 on the roof base material 13 such as plaster or mortar placed on the roof surface, the roof base material 13 is inserted into the concave portions 3, 3a of the back surface 2 of the tile roof body 1. The concave portions 3, 3a ... And the roofing base material 13 are in a state of being fitted in an innumerable uneven shape, and the contact area is remarkably enlarged, so that the concave and convex portions 3, 3a. It is firmly fixed with the material 13, so the roof base material due to the vibration of the earthquake or the force of the wind during strong winds
The separating action between the roof tile body 1 and the roof tile body 1 can be dispersed and supported by the respective concave portions 3, 3a ... And the roof base material 13 to prevent the roof tile body 1 from scattering and dropping.

Further, since the recesses 3, 3a ... On the surface 6 of the roof tile body 1 are formed in a hexagonal shape in plan view, the wind entering the recesses 3, 3a. Since the direction is changed randomly, it effectively works to reduce the flow velocity of the wind, reducing the peeling action,
By 3a ..., even a small amount of snow can be locked, the snow stopping function becomes extremely reliable, and the load on the tile roof can be reduced by distributing the snow load on each tile main body 1.

Also, by making the recesses 3, 3a ... Lightweight, it is possible to reduce the labor during transportation on the roof, and also to reduce the load on the base material and the structural material. Since the size is small, it is possible to reduce the construction cost.

Further, the roof tile main body 1 is reinforced by the honeycomb-shaped ribs 4 and 4a, and the weight is reduced by the concave portions 3 and 3a, but the strength is comparable to that of the conventional flat tile. Etc. The practical effect is enormous.
