Description

[Detailed explanation of the idea] This proposal relates to a successful improvement for use in the valleys of tiled roofs.

Conventionally, this kind of structure has been commonly used with a structure having a U-shaped cross section, in which the edges of the end tiles of the roof are placed on both side edges so that rainwater can fall.

In this configuration, where the lower part of the rainwater flow is largely exposed to the outside, rainwater is blown into the building when it rains under strong winds.

In order to prevent this, Utility Model Application Publication No. 433 of the Showa 1
As seen in the "Success" section of Publication No. 4, a configuration was proposed in which a shallow groove was placed in the center and deep grooves with a U-shaped cross section were adjacent to the left and right sides of the shallow groove. The design was based on the idea that residual rainwater would flow down from deep grooves on both sides of the shallow groove covered with roof tiles to prevent water from flooding into the attic due to wind.

However, if this configuration is successful, the main flow of rainwater will actually be in the side deep grooves, and the central shallow groove, which is exposed directly to the external wind at a high position, has little value; On the contrary, this makes the structure of the product more complex and increases both its shape and weight, making it inconvenient to handle and increasing the product cost, resulting in a lack of versatility.

This project was devised in view of the above-mentioned points, and by making slight improvements to the conventional most popular form with a U-shaped cross section, we attempted to provide a product of dramatically higher quality. It is something to do.

The present invention will be explained below with reference to the drawings.

Reference numeral 1 denotes the main body, which has a cross-sectional shape and forms a rainwater drainage groove 4 between the central vertical wall 2 and the left and right side walls 3, which is divided into left and right halves by the central vertical wall 2. is roof end tile A
A protrusion 5 whose edge A' collides to form a rainwater flow gap B.
has been established.

The main body 1 has a trapezoidal shape with a small lower width when viewed from above, and has an engaging groove 6 on the outer bottom surface of the lower end and a center groove on the upper end in order to overlap and connect each other. A part of the vertical wall 2 is cut out to form a continuous inner bottom surface of the left and right rainwater drainage grooves 4, and a retaining protrusion 7 adapted to the engagement groove 6 is provided.

Incidentally, reference numeral 8 in the figure indicates a stepped portion formed on the left and right side walls 3 in order to fit the lower end portion of the upper portion.

The present project is constructed as described above, in which a large number of roof tiles are sequentially connected from below in the roof valley, the roof end tiles A are placed on the left and right side walls 3, and their edges A' are connected to the center vertical wall 2
It is brought into contact with the projections 5 of the roof and used for roofing.

Then, the rainwater flowing down the roof falls into the rainwater drainage groove 4 through the gap B formed by the collision between the edge A' of the roof end tile A and the protrusion 5 of the central vertical wall 2, and is discharged. .

Therefore, according to this proposal, the end tiles of the roof are placed on the left and right side walls, and their edges are brought into contact with the protrusions of the central vertical wall to form a gap, so rainwater from the roof flows straight through the gap. The rainwater drainage capacity is improved by preventing rainwater from falling into the rainwater drainage ditch and causing temporary stagnation, and most of the rainwater drainage ditches are covered by roof tiles, which reduces the influence of external winds. Therefore, the rainwater flowing down the rainwater drainage ditch will not be blown into the attic, and furthermore, the edge of the end tile of the roof will not shift because it collides with the protrusion of the central vertical wall. Improve safety.

In addition, the successful form of the present invention is flattened as a whole in a cross-sectional shape, and has protrusions on the central vertical wall and both sides thereof, so the structure is simple and lightweight, and it is convenient to handle. It has various practical effects, such as using fewer materials and lowering the product cost.
