Abstract

PURPOSE:To improve stacking quality of a roof tile prevented from its lateral and longitudinal displacement by arranging the roof tile so as to position a rear side surface of its reinforcing rib almost in the reverse side of a water stop rib in its front side surface further forming a mountain part so as to spread its width from a rear edge over to a front edge. CONSTITUTION:A mountain part 11 and a hollow part 12 are alternately arranged in a corrugated roof tile 1 providing a reinforcing rib 14 stoppable to a tile batten 2 in a rear edge in its reverse surface and a water stop rib 15 in the rear edge in its obverse. Both the ribs 14, 15 are arranged so that a rear side surface 141 of the reinforcing rib 34 is positioned almost in the reverse side of a front side surface 151 of the water stop rib 15. While the mountain part 11 is formed in a tapered shape so as to spread its width gradually from the rear edge over to the front edge. And the fellow roof tiles 1, piled together, can be prevented from the lateral displacement by engaging the mountain part 11 with the hollow part 12 and from the rear direction displacement by engaging the reinforcing rib 14 with the water stop rib 15. While the displacement in the front direction is prevented because the mountain part 11 is formed in the tapered shape.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a corrugated roof tile. (Prior Art) A conventional corrugated tile is known, for example, as described in Japanese Utility Model Application Publication No. 102723/1983. This conventional corrugated tile has a rear reinforcing rib and a front reinforcing rib formed on the back surfaces of the trailing edge and the front edge, respectively, and a water-stopping rib is formed on the surface of the trailing edge, and the rear reinforcing rib and the water-stopping rib are different from each other. , were placed where the front and back sides overlapped. Therefore, when a plurality of corrugated tiles are stacked vertically, the upper corrugated tile overlaps with its crests and troughs engaging with the crests and troughs of the lower corrugated tile, respectively. In addition, the front reinforcing rib of the upper corrugated tile is cut out on the front edge surface of the lower corrugated tile, and the rear reinforcing rib is cut out on the water stop rib of the lower corrugated tile.

(Problem to be Solved by the Invention) Therefore, in such conventional corrugated tiles, when a plurality of corrugated tiles are stacked as described above, the rear edge is higher than the front edge by the height of the water stop rib. Not only does it become taller and the whole thing becomes slanted, but
The deviation movement in the arrangement direction of the peaks and valleys, that is, in the left-right direction, is
Although this can be prevented by engagement between the crests and troughs, there is nothing to restrict the movement of the crests and troughs in the flow direction, that is, in the front-back direction, resulting in poor stackability. Therefore, for example, as shown in Figure 9, when stacking corrugated tiles are temporarily placed on the roof surface when roofing, or as shown in Figure 10, corrugated tiles are transported in bulk by transport aircraft. In some cases, the stacked corrugated tiles could shift from each other and fall off the roof or from the transport aircraft.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide corrugated tiles that can prevent the wave tiles from shifting in the left-right and front-rear directions when stacked, and have good stackability.

(Means for Solving the Problems) In order to achieve the above object, the corrugated tile of the present invention has peaks and valleys arranged alternately, and the back surface of the trailing edge is reinforced so that it can be locked to the tile crosspiece. In a corrugated tile in which a rib is formed and a water-stopping rib is formed on the surface of the rear edge, the reinforcing rib and the water-stopping rib are arranged so that the rear side of the reinforcing rib is located almost on the back side of the front side of the water-stopping rib. The water stop ribs are arranged offset from each other, and the mountain portion is formed in a tapered shape so that the width increases from the rear edge toward the front edge.

(Function) When a plurality of corrugated tiles of the present invention are stacked vertically, the vertically adjacent corrugated tiles will have the peaks and troughs of the upper corrugated tile and the peaks and troughs of the lower corrugated tile mutually. At the same time, the rear surface of the reinforcing rib of the upper corrugated tile and the front surface of the water stop rib of the lower corrugated tile engage with each other. Therefore, the stacked corrugated tiles are prevented from shifting in the left and right direction by the engagement between the peaks and valleys, and the engagement between the rear side of the reinforcing rib and the front side of the water stop rib. This prevents displacement in the rear direction, and the tapered shape of the crest, which increases in width from the rear green to the front edge, prevents displacement in the forward direction. It turns out. (Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, the configuration of the first embodiment shown in FIGS. 1 to 5 will be explained. As shown in FIGS. 1 and 2, the wave tile l of this embodiment has the following features:
This is a round corrugated tile in which three peaks 11 formed in a semi-cylindrical shape and three valleys l2 formed with a flat bottom are alternately arranged.

The peak portion 11 is formed in a tapered shape so that the diameter increases from the rear edge toward the front edge, and the valley portion l2 is formed in the peak portion 1.
1, it is formed so that the width becomes narrower from the rear edge to the front edge.

Moreover, a nail hole I3 with a bottom is formed in the surface of the peak l1 of the trailing edge that overlaps with the adjacent corrugated tile 1 on the ridge side in the roofing state.

Further, on the back surface of the valley portion I2 of the trailing edge, a rear reinforcing rib l4 that can be engaged with the tile crosspiece 2 is formed extending in the left-right direction, and on the surface of the trailing edge, a rear reinforcing rib l4 is formed extending over almost the entire length in the width direction. Water stop ribs l5 are formed. In addition, on the back side of the front edge, the rear reinforcing rib l
A front reinforcing rib 16 having substantially the same height as 4 is formed over substantially the entire length in the width direction.

Further, the rear reinforcing rib I4 and the water stop rib I5 are staggered so that the rear side surface 141 of the rear reinforcing rib I4 is located substantially on the back side of the front side surface 151 of the water stop rib 15.

Next, the operation of the first embodiment will be explained. As shown in FIGS. 3 and 4, when a plurality of corrugated tiles l of this embodiment are stacked vertically, the vertically adjacent corrugated tiles 1.1 will have the peaks 11 and troughs of the upper corrugated tiles l. The portion l2 and the peaks 1l and troughs l2 of the lower corrugated tile 1 engage with each other, and the rear surface 141 of the rear reinforcing rib 14 of the upper corrugated tile l and the water stop rib of the lower corrugated tile 1 The front side surface 151 of l5 engages with each other. Therefore, the stacked corrugated tiles 1.1 are prevented from shifting in the left-right direction by the engagement between the peaks 1l and the troughs l2, and the rear side surface 1 of the rear reinforcing rib 14 is prevented from shifting in the left-right direction.
41 and the front side surface 151 of the water stop rib 15 prevents displacement in the rear direction.
The tapered shape that widens from the rear edge to the front edge prevents it from shifting forward. As described above, since the corrugated tiles 1 of this embodiment have good stackability, they can be used, for example, when stacked corrugated tiles l are temporarily placed on the roof 4 when roofing, as shown in FIG. , No. 1O
As shown in the figure, when the corrugated tiles 1 are transported together by the transporter 5, there is no fear that the corrugated tiles l will shift and fall off the roof 4 or the transporter 5, which is convenient. In addition, when installing the corrugated tiles 1, as shown in FIG. Drive a nail (not shown) through nail hole l3 to fix it. Then, on the rear edge, there is a wave tile l next to the ridge side.
The front edges of the roofs are overlapped, and the roof is successively covered from the eaves to the ridge. Then, in the area where the wave tiles l overlap, there is a water stop rib l5 of the wave tile l on the eave side, and a front reinforcing rib l6 of the wave tile l on the ridge side.
A hollow portion 17 is provided between the tile frame 17 and the hollow portion 17. This hollow portion 17 prevents rainwater from creeping up due to capillary phenomenon, etc., and prevents corrosion of the tile beams 2, roofing boards 3, etc. due to rainwater creeping up. It can be prevented. Next, a second embodiment shown in FIGS. 6 to 8 will be described.

In describing the second embodiment, structures similar to those of the first embodiment are given the same reference numerals followed by a and their explanations will be omitted.

Further, regarding the operations, explanations of operations similar to those of the first embodiment will be omitted.

In the corrugated tile 1a of this embodiment, the peaks 11a are formed in a triangular shape, the water stop ribs 15a are provided on the rear edge surface of the valleys 12a, and the rear reinforcing ribs 14a are provided on the back surface of the valleys 12a. It is provided extending in the direction. Therefore, the rear side surface 141a of the rear reinforcing rib 14a and the front side surface 151a of the water stop rib 15a engage with each other, thereby preventing displacement in the rear direction when a plurality of corrugated tiles 1a are stacked vertically. I can do something.

In addition, a width 18 is ensured between the rear side surface 141a of the rear reinforcing rib 14a and the rear surface 161a of the front reinforcing rib 16a. By placing it in the wide groove 18 of the tile 1a, the wave tile 1a. la can be stacked on top of each other. In addition, wave tiles 1a. The overlapping width of la can be adjusted within the range where the water stop rib l5a is within the width of 18 mm. Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the invention, they are included in the present invention. It will be done. For example, in the embodiment, the rear reinforcing ribs l4 are formed in the troughs l2, but they may be formed continuously over the entire length in the left-right direction including the peaks ll.

Further, the nail hole 13 may be a through hole penetrating the back surface of the corrugated tile l. (Effects of the Invention) As explained above, in the corrugated tile of the present invention, when a plurality of corrugated tiles are vertically stacked, the corrugated tiles do not shift from each other in the left-right and front-back directions. This has the effect of improving stackability.
