Description

  The present invention relates to a roof tile that is stacked and constructed on a roof ridge by a wet method using mortar, thatched clay, foaming resin, or the like.

  Conventionally, roof tiles stacked on roofs such as large ridges and corner ridges have been tied together with copper wires, etc., and each tile is laid with a piece of copper wire, etc. Although it is intended to prevent the roof tiles from falling off due to earthquakes, typhoons, etc. by connecting them together, these construction methods have the disadvantage that they are very time consuming.

Therefore, as described in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2000-27376) and Patent Document 2 (Japanese Utility Model Laid-Open No. 5-77413), the front tile and the rear face of the roof tile are respectively projected. There is a structure in which the roof tiles are prevented from falling off by locking the protrusions of the upper and lower roof tiles when the roof tiles are stacked on the ridge.
Japanese Patent Laid-Open No. 2000-27376 (FIG. 1, FIG. 2, etc.) Japanese Utility Model Publication No. 5-77413 (Figs. 2 and 3)

  In general, a roof tile is formed by forming a primary shape by extrusion molding and then forming a final shape by press molding. However, in the above described roof tiles of Patent Documents 1 and 2, the drop prevention protrusions are not provided uniformly over the entire length of the roof tile, but are provided separately at a plurality of locations on the roof tile. Therefore, there is a drawback that the cavity shape of the mold for press-molding the roof tile is complicated and molding defects are likely to occur.

  The present invention has been made in consideration of such circumstances. Accordingly, an object of the present invention is to provide a roof tile capable of improving formability while having a function of preventing dropout. is there.

  In order to achieve the above object, the invention according to claim 1 is directed to a roof tile which is constructed by stacking on a roof ridge by a wet construction method, and has projections extending in a substantially parallel direction on the front and back sides of the roof tile. The section of the roof tile is provided with a substantially constant cross-section over the entire length of the roof tile, and the protrusion on the back side of the roof tile is on the upper side when stacked on the ridge. It is formed so as to be prevented from falling off by being locked to the protrusion.

  In this configuration, the protrusion on the back side of the roof tile that is on the upper side when stacked on the ridge is locked to the protrusion on the front side of the roof tile that is on the lower side. It is possible to prevent the roof tiles from falling off toward the outside of the ridge. Moreover, since the protrusions for preventing dropout are provided over almost the entire length of the roof tile with a substantially constant cross section, the roof tiles are press-molded as compared with the case where the protrusions for dropout prevention are provided in multiple locations. The cavity shape of the mold to be performed can be simplified, and the occurrence of molding defects can be reduced. Furthermore, it becomes possible to shape the shape of the protrusion to some extent by extrusion molding before press molding.

  In general, when stacking roof tiles on the ridge, the upper roof tiles are stacked while being shifted by half the overall length in the direction parallel to the ridge. In order to align the end faces of the stacked tiles at the end, it is necessary to use the tiles cut in half. The roof tile of the present invention is provided with protrusions for preventing falling off and having a substantially constant cross section over the entire length, so that even when the roof tile is cut in half or in a size other than half, it is prevented from falling off. Therefore, there is an advantage that no special work needs to be performed to prevent falling off.

  By the way, if the height dimension of the protrusion for preventing dropout is increased, the depth dimension of the cavity for molding the protrusion of the mold for press-molding the roof tile is increased, so that the molding material (clay Or the like) may not easily reach the tip of the cavity for forming the protrusion, which may make it difficult to form the protrusion.

  Therefore, as in claims 2 and 3, a step may be provided on the front and / or back surface of the roof tile with the protrusion for preventing dropout as a boundary. In this way, since the depth dimension on one side of the cavity for press-molding the protrusion can be reduced, the molding material (such as clay) can easily reach the tip of the cavity for molding the protrusion. The formability of the roof tile (projection) can be improved. Moreover, waterproofness can also be improved by allowing the step provided on the surface of the roof tile to function as a water return.

  Conventionally, when stacking roof tiles by wet method using mortar, thatched clay, foaming resin, etc., it is necessary to adjust the parallelism of each roof tile with mortar, thatched clay, foaming resin, etc. Unless it is an expert, it was difficult to stack the roof tiles almost in parallel.

  Therefore, as described in claim 4, when the tiles are stacked on the ridge, the protrusions on the front side of the roof tiles are brought into contact with the back surface of the roof tiles on the upper side. You may form so that a parallelism may be ensured. Alternatively, as described in claim 5, the tiles stacked by bringing the protrusions on the back side of the tiles on the upper side into contact with the surface of the tiles on the lower side when stacked on the ridge You may form so that the parallelism of this may be ensured. In this way, it is not necessary to adjust the parallelism of each roof tile with mortar, thatched clay, foaming resin, etc., and even if you are not an expert, you can easily ensure the parallelism of the stacked roof tiles It is possible to construct a roof tile easily.

  In addition, as described in claim 6, the protrusion on the front side of the roof tile which is on the lower side when stacked on the ridge is brought into contact with the height adjusting portion provided on the back side of the roof tile on the upper side. It may be formed so as to ensure the parallelism of stacked tiles. Alternatively, as described in claim 7, the protrusion on the back side of the roof tile that is on the upper side when stacked on the ridge is in contact with the height adjustment portion provided on the front side of the roof tile on the lower side. It may be formed so as to ensure the parallelism of the stacked tiles. Even in this case, the parallelism of the stacked roof tiles can be easily ensured, and the roof tiles can be easily constructed.

  Hereinafter, the best mode for carrying out the present invention will be described using four Examples 1 to 4.

A first embodiment of the present invention will be described with reference to FIGS.
First, a schematic configuration of a ridge 11 such as a large ridge or a corner ridge will be described with reference to FIG. In the ridge portion 11, a plurality of roof tiles 13 are stacked on the top surfaces of the left and right side roof tiles 12 by a wet method using a ridge material 14 such as mortar, thatched clay, and foaming resin.

The crown tile 15 is tightly coupled to a ridge core material 18 attached to a reinforcing bracket 17 or the like using a metal wire 16 such as a copper wire or a stainless steel wire.

  As shown in FIG. 2, on the back side of the central portion of the roof tile 13 before construction, a split groove 19 is provided over almost the entire length of the roof tile 13 (or a range slightly shorter than the total length), The roof tiles 13 are stacked on the ridge 11 in a state of being divided into left and right along the split groove 19. Further, on the right side and the left side of the roof tile 13, surface-side protrusions 20 extending in a direction substantially parallel to the split groove 19 are formed in a substantially constant cross section over the substantially entire length of the roof tile 13. Provided on the right side and left side of the back tile 13 are back side projections 21 extending in a direction substantially parallel to the split groove 19 and having a substantially constant cross-section and extending over the entire length of the roof tile 13. Is provided.

  As shown in FIG. 3, when the roof tile 13 is stacked on the ridge portion 11 in a divided state, the back-side protrusion 21 of the roof tile 13 on the upper side becomes the lower side of the roof tile 13. By locking to the front-side projection 20, it is possible to prevent the ridge 11 from falling off and shifting in the outer direction, and to make the chilli width H (the dimension between the outer end faces of the upper and lower roof tiles 13) substantially constant. It can be done. Moreover, as shown in FIG. 1, the shift | offset | difference to the inner side direction of the ridge part 11 of the roof tile 13 is controlled by the ridge material 14 such as mortar, thatched clay, and foaming resin. Furthermore, the crown tile 15 can be prevented from falling off and shifting by the surface side protrusion 20 of the uppermost roof tile 13.

  Further, as shown in FIG. 3, the roof tile 13 is provided with a step so that the inner surface is higher than the outer surface than the front surface protrusion 20, and accordingly, the rear surface protrusion A step is provided so that the inner back surface is higher than the back surface outside 21. In this case, it is possible to prevent rainwater and the like from entering the inside of the ridge 11 by causing the step provided on the surface side protrusion 20 of the roof tile 13 to function as a water return.

  Furthermore, when the roof tile 13 is stacked on the ridge portion 11 by using the portion whose surface is higher on the inner side than the surface side projection 20 as the height adjustment portion 22, The parallelism of the stacked roof tiles 13 can be ensured by bringing the back-side projection 21 into contact with the height adjusting portion 22 provided on the front surface side of the roof tile 13.

  Further, as shown in FIG. 4, the roof tiles 13 before being divided do not interfere with the front-side projections 20 and the rear-side projections 21 of the respective roof tiles 13 when a plurality of tiles are stacked. It is formed into a shape. This prevents the front side protrusions 20 and the rear side protrusions 21 of each roof tile 13 from interfering and being damaged when a plurality of sheets are stacked and bundled with the tape 23 or the like. I have to.

  In the first embodiment described above, when the roof tile 13 is stacked on the ridge 11, the back-side protrusion 21 of the roof tile 13 that is on the upper side is the lower surface protrusion of the roof tile 13 that is on the lower side. Since it is prevented from falling off or slipping off the roof tile 13 due to an earthquake, a typhoon, or the like, the construction with high disaster prevention performance can be realized. In addition, since the protrusions 20 and 21 for preventing the dropout are provided over almost the entire length of the roof tile 13 having a substantially constant cross section, the protrusions for preventing the dropout are provided in a plurality of locations. The cavity shape of the mold for press-molding the roof tile 13 can be simplified, the occurrence of molding defects can be reduced, and the yield can be improved. Furthermore, it becomes possible to shape the shape of the protrusions 20 and 21 to some extent by extrusion molding before press molding.

  In general, when stacking the roof tiles 13 on the ridge 11, the upper roof tiles 13 are shifted from the lower roof tile 13 while being shifted by half of the overall length in the direction parallel to the ridge 11. Therefore, in order to align the end surfaces of the stacked tiles 13 at the ridge end, it is necessary to use the tiles 13 cut in half. The roof tile 13 according to the first embodiment is provided with the protrusions 20 and 21 for preventing the drop-off and having a substantially constant cross-sectional shape over almost the entire length. Therefore, when the roof tile 13 is cut in half or in dimensions other than half. Even when it is cut, the protrusions 20 and 21 for preventing the dropout can always be left, and there is an advantage that it is not necessary to perform special work for preventing the dropout.

  Furthermore, in the first embodiment, since the step is provided so that the inner surface is higher than the outer surface of the surface tile 20 of the roof tile 13, the surface side protrusion 20 is press-molded. The depth dimension of one side of the cavity to be made can be reduced, and the molding material (clay or the like) can easily reach the tip of the cavity for molding the surface side protrusion 20, and the roof tile 13 (surface side protrusion) The moldability of 20) can be improved. Moreover, by making the level difference provided on the surface side protrusion 20 of the roof tile 13 function as a water return, the waterproof property can be improved, and the mortar, thatched clay, foaming resin, etc. inside the ridge 11 It is possible to prevent the ridge material 14 from being washed away with water or deteriorated.

  In the first embodiment, when the roof tile 13 is stacked on the ridge 11, the rear-side protrusion 21 of the roof tile 13 that is on the upper side is provided on the surface side of the roof tile 13 that is on the lower side. Since the parallelism of the stacked roof tiles 13 is ensured by being brought into contact with the height adjusting portion 22, the parallelism of the roof tiles 13 is parallel with the building material 14 such as mortar, thatched clay, and foaming resin. The degree of parallelism of the stacked roof tiles 13 can be easily ensured and the installation of the roof tiles 13 can be easily performed even if it is not an expert.

  In the first embodiment, a step is provided on both the front and back surfaces of the roof tile 13, but a step may be provided only on the front surface of the roof tile 13. Further, as in the modification shown in FIG. 5, the height adjustment is performed on the surface side of the roof tile 13 and on the inner side of the front side projection 20 without providing a step on either the surface or the back surface of the roof tile 13. When the roof tiles 13 are stacked on the ridge 11, the back side projection 21 of the roof tile 13 is on the lower side. You may make it ensure the parallelism of the piled tile 13 by making it contact | abut to the height adjustment part 22 provided in the surface side of the tile 13. FIG.
