Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the improvement of a roof tile. In particular, the present invention relates to a roof tile having a cutout on the butt side and a cutout on the head side, in which the cutout portion on the head side is reinforced.

[0002]

[Prior art]

 As is known, this type of traditional roof tile has square notches on the hip side and the head side respectively, and the roofing is made on the head side notch of one roof tile and the other roof tile of the other roof tile. The basic method is to fit a vertical piece on the ridge pass side that is formed near the notch on the hip side and a horizontal piece that is formed at a right angle to the vertical piece (hereinafter referred to as the hip side insertion part) Has been implemented as.

However, in the conventional example of this type, as described above, since the roof roof of the crosspiece is merely in contact with the cutout on the head side, the bottom side insertion portion of another crosspiece is in contact, the stress in the left and right direction is increased. Even though it can withstand the vertical direction, it is free from vertical stress, so it is possible to lift it by traditionally applying nailing to the hip side together with the weight of the roof tile. It's just trying to control.

As a result, even if reinforcement of the hip side can be expected to some extent by the dead weight of the crosspiece and the nailing, the head side can be prevented from being lifted up only by the dead weight that is played by simply stacking the crosspieces. Stop

Therefore, in order to solve the drawbacks of the conventional example, an improved invention disclosed in Japanese Patent Laid-Open No. 62-112854 has been proposed.

In this improved example, as described in the publication, a notch is provided at the intersection of the butt and the crossing ridge, the cutout is projected to the butt side on the crossing pass side, and An insertion piece with a thickness smaller than that of the main part of the roof tile is provided on the surface side of the section, a notch is provided at the intersection of the head and the collar, and a part of the notch is closed on the inner side of the notch. Is a crosspiece that is provided closer to the rear surface of the main body of the crosspiece in correspondence with the crosspiece and has a wall thickness smaller than that of the main part of the crosspiece. The insert piece on the bottom side of the other sash is placed on the top.

[0007] Therefore, since the roof tile is improved compared to the traditional crosstile, it can withstand stress not only in the horizontal direction but also in the vertical direction when roofing, so that the tile can be protected against disasters such as typhoons and earthquakes. It can be evaluated for its ability to suppress movement and lifting.

However, although it has the above-mentioned advantage, the insertion piece and the insertion piece receiving portion provided in the cutout portions on the hip side and the head side have to be formed thinner than the wall thickness of the main portion of the ridge. As a result, there was a secondary problem, in particular, that the receptacle for the insert was damaged in the event of a disaster.

Therefore, although the improved example improves the structure of the traditional crosstile, it is still not sufficient unless the secondary problem described above is solved.

Further, since the collar side of the receiving portion for the inserting piece is open, when the inserting piece is placed on the receiving portion for the inserting piece and is used for the roof, the rainfall flowing along the side of the collar is cut off on the head side. There is also a risk that it may flow out from the notch onto the receiving part for the insert piece, and may infiltrate below the notch on the butt side of another adjacent sash, and damage the roof.

[0011]

[Problems to be solved by the device]

 The problem to be solved by this invention is that, in the above-mentioned type of roof tile, the receiving portion for the insertion piece of the notch portion on the head side is easily damaged when the roof tile is roofed.

Further, since the collar side of the receiving portion for the inserting piece is open, when the inserting piece is placed on the receiving portion for the inserting piece and is used on the roof, the rainfall flowing along the side of the collar is cut off on the head side. There was also a risk that the roof would be damaged by spilling out from the notch onto the receiving part for the insert piece and penetrating below the notch on the butt side of another adjacent sash.

The object of the present invention is to maintain the advantage of the above-mentioned improvement plan of the above-mentioned type of the roof tile, and at the same time, to prevent damage to the receiving part for the insert piece which occurs as a secondary problem of the improvement plan at the time of roofing. To prevent this, and to prevent rain from penetrating below the notch on the bottom side of another adjacent roof tile when in use.

[0014]

[Means for Solving the Problems]

 The basic structure of the invention of the first ridge is that the ridge is provided with a notch at the intersection of the butt and the ridge, the ridge is protruded to the butt side of the notch, and the surface side of the main body of the ridge is An insert piece with a thickness smaller than that of the main body of the stake is provided, a cutout is provided at the intersection of the head and the collar, and a part of the cutout is closed to the inside of the cutout to close the main portion of the stake. This is a crosspiece that is provided on the back side of the main part of the crosspiece in correspondence with the insert piece and has a reinforcement part of a certain thickness provided on the back side of the insert piece receiving part. It is designed so that the receiving part for the insert piece will not be damaged during roofing.

The basic structure of the second crosspiece device is that in the first device, a partition wall is inserted from the end on the head side of the collar at the intersection of the collar side and the head side collar of the insertion piece receiving portion. It is installed on the one-side receiving part.

[0016]

[Action]

 The insertion piece provided in the notch on the tail side of the other roof tile is placed on the receiving portion for the insertion piece provided on the head side notch of the other roof tile. Thus, since the insert piece and the insert piece receiving portion are fitted to each other in a concavo-convex state, the insert piece and the insert piece receiving portion are less likely to move or float up not only in the lateral direction but also in the vertical direction.

In addition, since the reinforcing portion is formed on the back surface of the receiving portion for the insertion piece, the strength of the receiving portion for the insertion piece is conventionally weak, and there is a possibility that the receiving portion for the insertion piece may be damaged in the event of a disaster such as a typhoon or an earthquake. The object is less likely to be damaged by providing the reinforcing portion.

Further, it is possible to prevent rainfall from entering below the notch on the butt side of another adjacent roof tile when in use.

【Example】

 The details of this invention will be described with reference to the drawings. 1 is a front perspective view of the roof tile, FIG. 2 is a rear perspective view of the roof tile, FIG. 3 is a plan view, FIG. 4 is a plan view showing a state where the roof tile is roofed, and FIG. 5 is a line AA of FIG. FIG.

As is apparent from FIG. 1 and the like, the cross tile 40 according to the present invention is provided with a substantially rectangular notch 14 at the intersection of the butt 10 and the cross pass 12, and the cross of the notch 14 is provided. An insert piece 18 is provided on the pass 12 side, protruding toward the butt 10, and on the surface side of the crosspiece main body 16 with a thickness smaller than that of the crosspiece main body 16. The insert piece 18 is supported on an insert piece receiving portion 26 formed in a notch 24 on the head 20 side, which will be described in detail later.

A notch 24 is provided at the intersection of the head 20 and the collar 22, and a part of the notch 24 is closed to the inner side of the notch 24 so as to make the insert piece thinner than the wall thickness of the main body 16 of the roof tile. The receiving portion 26 is provided on the back surface side of the crosspiece main body portion 16 corresponding to the insertion piece 18 described above.

The crosspiece 40 having such a structure has the insertion piece 18 and the insertion piece receiving portion 26 provided on the hip 10 side and the head 20 side, respectively, as described above. It is advantageous as compared with the conventional traditional stile by placing the slab on the insertion piece receiving portion 26.

However, since the wall thickness of the insert piece 18 and the insert piece receiving portion 26 is generally about one half of the wall thickness of the crosspiece main body portion 16, in particular, the insert piece receiving portion 2 6 is easily damaged when roofing. Therefore, in this invention, the back surface of the insertion piece receiving portion 26 is provided with the reinforcing portion 28 having a constant thickness.

The reinforcing portion 28 is implemented by slightly increasing the thickness of the back surface of the insertion piece receiving portion 26. Of course, the reinforcing portion 28 can be easily formed by adjusting a part of the lower mold when molding the clay.

On the other hand, the insert piece 18 provided in the notch 14 on the side of the hip 10 has a thin back surface, and although it is generally expected that the insert piece 18 lacks in strength, the insert piece receiving portion 28 and On the other hand, the load is exerted on the insertion piece receiving portion 26 at the time of roofing, but no load is applied to the insertion piece 18. Therefore, according to the experiment by the inventor, the insertion piece 18 has a special strength. It is confirmed that there is no need to increase.

In addition, in the case of the roof tile 40 of this type, in order to suppress the infiltration of the rainfall to the side of the intersection between the butt and the rail pass, which may occur at the time of roofing, in order to suppress the infiltration of rain, the side of the collar 22 of the receiving portion 26 for the insert piece is suppressed. A partition wall 30 is provided at an intersection of the collar 22 and the collar 22 on the head 20 side so as to hang from the surface of the collar 22 to the receiving piece receiving portion 26. The symbols "32", "34", and "36" are so-called water repellents, respectively.
