Description

  The present invention relates to an improvement of a disaster prevention roof tile excellent in wind resistance and earthquake resistance.

  Conventionally, in a tiled roof structure, a ridge portion, which is the top portion, is a portion that is susceptible to external force. For example, it is susceptible to repeated external forces due to vibrations during earthquakes and strong wind pressures during typhoons, etc., and prevention of accidents such as turning up of tiles resulting from the collapse of buildings and falling is an important issue in the industry. ing.

  Many proposals have been made for this purpose. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-146971), a roof tile intended for earthquake resistance and wind resistance is provided with a locking projection extending in the axial direction on the butt end surface on the back surface, and a locking receiving on the other end surface. A structure having a portion has been proposed. The ridge tile of this structure strengthens the mutual cooperation so as to prevent the displacement in the direction perpendicular to the ridge direction or the lifting of the tile by engaging the locking projection with the locking receiving portion. Since the locking projection, which is an important part, protrudes in the axial direction, it cannot be formed simultaneously with the molding of the main body during the automatic press molding of the clay body, and thus there is a problem that separate post-processing is required.

  In Patent Document 2 (Japanese Patent Laid-Open No. 2004-60416), two anti-slip projections of the pier and two anti-slip projections of the crown tile are attached to the surface of the uppermost roof tile body, and the crown tile itself is tightly coupled. A structure that is fixed with a wire has been proposed. In this structure, the roof tile itself follows the traditional fixing method of fixing with a fastening line, and the number of man-hours for tile roofing increases by forming a very special structure on the top roof tile. There was a problem.

  Furthermore, Patent Document 3 (Japanese Patent Laid-Open No. 2002-138630) is intended to prevent lifting and right / left misalignment by providing notch recesses and fitting protrusions that mesh with each other at four corners of both ends of a round crown tile. However, since the structure is complex and automatic press molding cannot produce such uneven portions, manual post-processing is required, resulting in high costs.

  The present invention has been made to solve the above-described problems, and can be used for press forming of a crown tile body without requiring special post-molding processing, etc., and the installation work itself is not changed from the conventional one. Providing disaster prevention tiles that have excellent earthquake resistance and wind resistance.

  The above problem is a crown tile that is long and continuous in the longitudinal direction from one end to the other end, and is provided with a string portion at one end and the other end. The insertion part to be inserted into the lower side of the string part of the adjacent roof tile is sometimes formed, and a protrusion is formed along the end surface on the surface of the insertion part. This can be solved by the disaster prevention tile according to the present invention (first invention), characterized in that a groove is formed to engage with the ridge.

In addition, the above problem is that the roof tile has a long length in the longitudinal direction from one end to the other end that is continuously provided in a row at the top of the ridge, and has a cross section that crosses the longitudinal direction from one end to the other end. It is formed in a circular arc shape, and is provided with a continuous insertion protrusion at one end, and the other end is a continuous portion that overlaps the adjacent insertion protrusion of the adjacent roof tile when erected, and the continuous insertion protrusion The present invention is characterized in that a ridge is formed on the front surface along the end surface, and a concave groove that engages with the ridge of the crown tile adjacent to each other at the time of installation is formed on the back surface of the continuous portion. (2 invention) can be solved by the disaster prevention tile.

  In addition, the present invention can be embodied in a form in which the ridges are formed intermittently, and the concave grooves are formed in correspondence with the intermittent ridges. Further, a water draining groove is formed along the ridges. It can preferably be embodied in the provided form.

  In the disaster prevention tile according to the present invention, the protrusions and grooves provided at both ends of the tile engage with the grooves and protrusions of the tiles installed adjacent to each other at the time of installation. Since the continuous state of the tiles is maintained, preferable earthquake resistance and wind resistance performance are exhibited. Furthermore, the concave grooves and ridges can be molded simultaneously with the press-molding of the crown tile body without requiring special post-molding processing, etc., so there is no increase in cost, and the laying construction itself is not different from conventional ones. There is an excellent effect that can be done. Therefore, the present invention has a very large practical value as a disaster prevention tile that has solved the conventional problems.

(First embodiment)
Next, 1st Embodiment which concerns on the disaster prevention roof tile of this invention is described, referring FIGS.
At the top of the roof structure, as shown in FIG. 3, a plurality of roof tiles 13 are stacked on the top of the rolled up roof tile 11 with the core material 12 provided along the top as a core. There are many examples of roof tile ridges that are fixed and covered with a series of crown tiles 2 and fixed with long screw members 14 or the like. The subject of the present invention is the crown tile 2 that is erected in series along such a ridge top. In this case, a roof tile having an arcuate cross section is taken as an example.

  The disaster prevention tile according to this embodiment is a crown tile 2 installed in series on the top of such a ridge, and at one end thereof, a string portion 3 bulging and covering the entire end is provided. An arc-shaped notch 31 extending in the inner circumferential direction is provided inside. And the other end part is the insertion part 4 inserted in the said notch part 31 provided inside the string part 3 of the adjacent crown tile at the time of installation, Comprising: At the time of installation, the string part of an adjacent tile The three cutout portions 31 are overlapped with the insertion portion 4 so that there is no gap, and the crown roof tiles are arranged in a row.

  As illustrated in FIG. 1, the feature of the present invention is that the surface of the insertion portion 4 (see FIG. 1A) has a width: 3 mm to 12 mm, a height: 3 mm to 12 mm, and a length. 10% or more of the width of the insertion portion 4 is formed along the end face, and the cutout portion 31 of the string portion 3 (see FIG. 1B) has an arc shape. A concave groove 32 is formed on the back surface along the inner circumferential direction, and the concave groove 32 is overlapped with the protruding line 41 provided in the insertion portion 4 of the adjacent roof tile at the time of laying and provided so as to be engageable. It is in the point.

  As described above, the disaster prevention tile of the present invention is provided on the back surface of the protruding portion 41 provided on the surface of the insertion portion 4 and the cord portion 3 cutout portion 31 on the other end side in the roof structure provided as described above. Since the concave grooves 32 are fitted to the similar concave grooves 32 and ridges 41 of the tiles installed adjacent to each other and engaged and held in a continuous state, the arrangement state is mutually restrained. In other words, favorable earthquake resistance and wind resistance performance are exhibited.

  Further, in the present invention, the concave groove 32 is formed on the back surface of the string portion 3 bulging and covering the entire end portion, so that a sufficient thickness can be maintained. Since it is formed on the surface of the insertion part 4 holding a sufficient thickness, the unevenness of both does not reduce the mechanical strength of the roof tile.

  Furthermore, since the groove 32 and the ridge 41 can be formed at the same time as the main body of the crown tile 2 is press-molded, it does not require special post-molding processing and the like, and the cost is significantly increased. In addition, since the laying construction itself only superimposes the string portion 3 on the insertion portion 4, there is an excellent effect that there is no particular increase in cost in this respect without any change from the conventional one.

  Further, in the present invention, the ridge 41 is formed intermittently (see FIG. 2D), and the groove 32 is formed intermittently corresponding to the intermittent ridge 41 (FIG. 2E). If it is referred to), the continuous installation at the time of installation will become stronger, which is preferable in terms of wind and earthquake resistance.

Moreover, when the draining groove 42 is provided along the inner side of the ridge 41, the strength reduction based on the draining groove 42 is reinforced by the ridge 41, so that an advantage that does not become a weak point is obtained, and also during heavy rain This is more preferable for preventing flooding.
In addition, the crown tile of the present invention can be applied to various types of crown tiles such as string round tiles, round pier roof tiles, square pier roof tiles, box crown tiles, shin-maru tiles, Kyoto box tiles, and Kyobushima tiles. Needless to say.

(Second Embodiment)
Next, 2nd Embodiment which concerns on the disaster prevention roof tile of this invention is described, referring FIG. It is the same as the previous embodiment that this disaster prevention tile is a crowned tile that is formed in a series from the one end to the other end in order to be installed in series at the building top. It is. Further, the structure of the ridge top is configured similarly to that illustrated in FIG. In this case, a roof tile having an arcuate cross section across the longitudinal direction is taken as an example.

  The crown tile 5 of this embodiment is provided with a continuous insertion protrusion 6 protruding at one end, and the other end is overlapped with the adjacent insertion protrusion 6 of the adjacent roof tile when installed. This is a continuous portion 7. And this crown tile 5 is installed in a series by inserting and superposing this continuous insertion protrusion 6 on the lower side of the adjacent tile continuous portion 7. Since it does not have a string portion as in the form, it has a different appearance from the previous embodiment, and the ridge top portion has a substantially uniform linear appearance.

  And, as a feature of this embodiment, as shown in FIG. 4 (A), a convex strip 61 extending in the outer peripheral direction along the end face is formed on the surface of the connecting insertion protrusion 6 as shown in FIG. On the back surface of the continuous portion 7, a concave groove 71 that engages with the convex stripes of the adjacent roof tile at the time of installation is formed in a shape extending in the inner circumferential direction. Similar to the first embodiment, the dimensions of the ridges 61 are preferably width: 3 mm to 12 mm, height: 3 mm to 12 mm, and the length is 10% or more of the width of the protrusion 6 with the insertion.

  The disaster prevention tile according to the second embodiment of the present invention has a roof structure that is installed as described above, and the rear surface of the connecting portion 7 on the other end side, and the protrusion 61 provided on the connecting insertion protrusion 6. Since the concave grooves 71 provided in are fitted and engaged with the similar concave grooves 71 and ridges 61 of the tiles installed adjacent to each other and held in a continuous state, the arrangement state thereof is mutually determined. As a result of restraining each other, preferable earthquake resistance and wind resistance performance are exhibited as in the first embodiment.

  Further, the concave groove 71 and the ridge 61 can be formed simultaneously with the press-molding of the crown roof 5 main body, so that no special post-molding processing is required and the cost is remarkably increased. In addition, since the installation work itself is only overlapped with each other, it is the same as in the first embodiment that there is no significant increase in cost in this respect without any change from the conventional one. is there.

  As a modification of this embodiment (see FIG. 4 (B)), a convex strip 62 is formed on the surface of the continuous insertion protrusion 6 with a concave groove 63 provided along the end face. A form in which a concave groove 72 is formed in the inner circumferential direction so as to be separated from the end surface on the back surface of the portion 7 so as to be engaged with the ridges 62 of the adjacent crown tile at the time of installation is more preferably embodied.

  In this case, the function and effect of the ridges 62 and the grooves 72 are the same as those in the previous embodiment, and thus the description thereof will be omitted. It can be said that it is more effective because the arrangement state is constrained in the direction as well.

  Further, in the embodiment shown in FIG. 4, the ridges 61 are formed intermittently (see FIG. 5A) from the integrated one (see FIG. 5A), and the concave grooves 71 are intermittently formed. If it is formed intermittently (not shown) corresponding to the ridges 61, the continuous arrangement at the time of installation becomes stronger, which is preferable in terms of wind and earthquake resistance. This deformation is also effective in the case of FIG.

Moreover, in the case of FIG. 4, when the draining groove | channel 63 is provided in the outer side of the said protruding item | line 61 (refer FIG. 4 (A)), and the case where the draining groove | channel 63 is provided inside (refer FIG. 4 (B)). In any case, the draining groove 63 is not essential to the present invention, although it is more preferable for preventing flooding during heavy rain.
Moreover, it cannot be overemphasized that it can apply to various crown roof tiles, such as a turtle bottom, a 5-dimension round, a 5.5-dimension round, a 6-dimension round, and a bare round, as the crown tile of this invention.
