[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simplified roofing tile (referred to as a roofing tile) that can be easily made.
[0002]
[Prior art]
As is well known, in the case of the roof tiles of the main-frame shape flat and round structure (simplified main-frame roof tiles) that are widely used in traditional shrines and temples, etc. In the vicinity of the eaves and around the worship roots, the rainwater flow rate increases significantly, and measures against rain are becoming an important issue.
[0003]
This issue is largely due to the difference between the roof slope of the roof and the flow surface gradient of the tile (the so-called tile return gradient), and there is a long-awaited measure to prevent the stormwater from going up on the gently-sloped roof. .
[0004]
In addition, the simplified roof tiles are constructed with an overlapping surface of about 20-25% of the total length (over 60% is the overlap of the main roof tiles), and there is a problem of how to block rainwater blown to the bottom side. I have it.
[0005]
And there are many cases where two-stage roof tiles with steps on the surface of the water flow are flooded with run-up rainwater that is once interrupted at the step and detoured to the side of the fence, leading to rain leakage.
[0006]
Also, in the dry construction method that reduces the weight of the roof and compresses the construction cost and omits the dredged soil, it should be considered that rainwater overflowing from the bottom side and the side of the ridge directly leads to rain leakage.
[0007]
Conventionally, as technical literature on this type of simplified roof tile, there is (1) a roof tile for regular roofing of Japanese Utility Model Publication No. 59-42413 (Document (1)). The present invention is a main roof tile in which a flat roof tile curved so as to protrude downward and a semi-cylindrical round roof curved so as to face upward are integrally formed. It protrudes slightly from the flat roof tile, and the back of the round roof tile has a notch corresponding to the protrusion. By removing the protrusion of the round roof tile, the top and bottom (from the ridge to the eaves direction: flow direction) This is a configuration for adjusting the tile size (overlapping degree). (2) There is a roof tile for Japanese cypress (Japanese Patent Laid-Open No. 7-233593) (Reference (2)). The present invention integrally forms a flat roof portion curved so as to protrude downward and a semi-cylindrical round roof portion curved so as to face upward, and a stepped ball at the rear end of the circular roof portion. The main roof tile with a mouth part has a configuration in which uneven portions for preventing misalignment are formed on the front and rear ends of the round roof tile to fit the front and rear main roof tiles to be overlapped. There is little misalignment and scattering, and it can be easily replaced when damaged.
[0008]
[Problems to be solved by the invention]
The documents (1) and (2) do not disclose a configuration related to the surface inclination (gradient) from the stepped portion of the flat roof portion toward the bottom side or the head side. Therefore, there is a problem that it is impossible to expect and prevent the wind and rain from rising at this stepped portion. This problem is mainly caused by problems such as wetting of roofing land due to rainwater intrusion, and rarely scattering of roofing tiles due to wind intrusion.
[0009]
In addition, Documents (1) and (2) are not configured to provide a water flow zone that is lower than the water return ridge and secures the flow of rainwater from the bottom side to the head side inside the water return ridge. Therefore, there is a risk that the rainwater flowing on the surface of the main roof tile and the main roof tile (referred to as the tile) may be mainly diffused by the wind, and there are problems such as wetness of the roof due to the intrusion of rain water and rain leakage. appear.
[0010]
Reference (1) is a configuration in which the round tile portion of the tile slightly protrudes from the flat tile portion, and the degree of overlap is adjusted (kiking leg adjustment) through removal and non-removal of the protruding portion. The idea is different. Further, in this document (1), there is a problem that the relationship between the roof tiles adjacent to each other in the vertical direction (flow direction) cannot be achieved and the roof tiles are not sufficiently prevented from being displaced.
[0011]
Furthermore, the literature (2) has no description about water return, and it is considered that rainwater enters from the periphery of the roof tile.
[0012]
In view of the above, the present invention starts from the stepped portion of the flat tile portion, and the surface of the flat tile portion forms a downward inclined surface toward the butt side and an upward inclined surface toward the head side. Adopting (step shape), it is a roof tile that nurtures a heavy atmosphere that does not change the appearance when it is rolled up. In addition, the butt side overlap surface and the butt side end that rise upward from the descending inclined surface have a relatively high water return, which is effective for castration of the rainwater run-up and prevention of backflow.
[0013]
In addition, the flowing water zone formed between the step shape of the flat roof portion and the water return protrusion on the insertion side has a remarkable function of quickly draining the rainwater that has gone up. The stable protrusions provided on both shoulders of the flat tile portion have at least two effects such as improving the stability of matching with the upper roof tiles that are installed and improving the end.
[0014]
Furthermore, it is also possible to change the trough curvature of the head side and the bottom side of the protrusion of the safety protrusion so as not to impair the beauty.
[0015]
In the present invention, the reverse water stop groove provided on the back side head side end of the flat tile portion and the double weir formed on both sides of the reverse water stop groove are effective means for preventing the intrusion of rainwater that wraps around from the lower end of the water dripping. It is.
[0016]
[Means for Solving the Problems]
[0017]
In the first aspect of the present invention, a stepped portion provided at a substantially central position of the flow surface of the flat tile portion (exposed surface excluding the bottom overlapping surface) is defined as a vertical end surface, and the vertical end surface is a drooping head water of the flat tile portion. Since it is configured to be a vertical plane parallel to the plane, it is intended to alleviate the run-up of the wind and rain, improve the performance of rain, and prevent the scattering of tiles by strong winds. The invention of claim 1 is a configuration in which the stepped portion is the starting point, the surface of the flat tile portion forms a downward inclined surface toward the bottom side, and an upward inclined surface is formed toward the head side, If the downward slope is used as a reference, the water return ridge on the bottom side is relatively high, and it is intended to reliably prevent wind and rain that goes up (backflow). Furthermore, the invention of claim 1 is intended to secure the flow path of rainwater while ensuring the appearance of the main roof tile roof by limiting the stepped shape of the flat tile portion to the portion visible after construction. Further, the invention of claim 1 is intended to prevent vertical misalignment or scattering, and facilitate matching.

DETAILED DESCRIPTION OF THE INVENTION
The backside of the main tile (in principle, tiles A, A-1 and A-2) is brought into contact with a horizontal line fixed to the roof, and a hook (not shown) provided on the reverse side is provided on the horizontal line. ). The tiles can be reliably and easily lifted up on the roof by the engagement with the side ridges. When this is lifted up, the flat tile surface starts from the stepped portion provided at the approximate center of the flat tile portion, and then the surface of the flat tile portion becomes a downward inclined surface toward the buttocks side and rises toward the head side. It becomes an inclined surface. Thereby, the surface on the upstream side (ridge direction) becomes a downward inclined surface toward the bottom side, and the surface on the downstream side (in the eaves direction) becomes an upward inclined surface toward the head side. Moreover, it becomes the virtual surface line of a flat roof part by the termination | terminus of a downward slope and the termination | terminus of an upward slope. In addition, the stepped part provided at the approximate center position of the flat tile part is a vertical end face, and this vertical end face is a vertical plane parallel to the head water dripping surface of the flat tile part. Therefore, it is possible to improve the rain performance and prevent the scattering of the roof tiles by strong winds. In addition, after construction, it has the effect of fostering a profound atmosphere comparable to a traditional book roofing. In particular, even if the tile of the present invention has a significantly large amount of rainwater flow, such as around the eaves and the base of the worship, where the roof of the shrine roof has a remarkably gentle slope in buildings such as shrines and shrines with shrine roofs, It has the feature that rainwater on the bottom side surface can flow down to the head side reliably, and therefore has a tremendous benefit in rain countermeasures. In particular, rainwater that tends to collect on the water return ridge on the bottom side can be flowed to the head side of the roof tile A and reliably flow down to the bottom roof tile (not shown) by using the flowing water zone.
[0022]
In addition, on this roof tile A, a roof tile A-1 (referred to as an adjacent roof tile A-1) that is rolled in the girder direction (direction of the wife) is overlapped on the insertion side of the flat roof tile portion of the roof tile A. At this time, the stepped portion and the descending end surface and the ascending end surface provided on the face door portion of the adjacent tile A-1 are provided on the stepped portion and the descending inclined surface (descending surface) and the ascending inclined surface (ascending surface) of the tile A. Are in contact with each other. And the flowing water zone of the tile A is concealed by the round tile portion of the adjacent tile A-1. This flowing water zone is located at the overlapping portion of the roof tile A, the upper roof tile A-2, and the adjacent roof tile A-1, and serves as a water flow channel (drainage channel) that guides rainwater going up from the flat roof tile. And since this flowing water zone is substantially completely concealed by the round tile part and the face door part, a smooth flow can be secured without being disturbed by wind and rain. It is also useful for improving rain performance.
[0023]
Further, on this roof tile A, a roof tile A-2 (referred to as an upper roof tile A-2) that is rolled in the ridge direction is overlaid. That is, the head side of the flat roof tile of the upper roof tile A-2 and the head side of the round roof tile are overlaid on the bottom side surface and the mouth portion of the roof tile A-2, respectively. At the time of this multiple firing, the stable protrusion provided on the surface of the flat roof portion of the roof tile A, the stop step provided on the water return ridge, and the stepped muzzle portion connected to the round roof portion are In addition, the dripping head of the flat roof tile and the round roof tile of the upper roof tile A-2 is locked (stopped). This locking has features such as prevention of misalignment, achievement of certainty and ease of overlapping, positioning, etc., or facilitation of construction, wind and rain resistance, and the like. And after that, a nail stop is performed and the construction of the tile A is completed.
