Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material, and more particularly to a ventilating dry-type roofing material for supporting a roof tile of a tiled roof, which allows sufficient ventilation of the back of a shed. The present invention relates to a ridge roofing material that can more reliably prevent rainwater from entering the inside of the ridge.

[0002]

2. Description of the Related Art A ridge roofing material is a pedestal for supporting a crown tile of a tiled roof. The gap between the roof tile and the cross tiles on both sides of the roof tile is closed, and rainwater infiltrates from the ridge portion to the side of the base plate. To prevent The applicants of the present invention have previously improved the workability by using a synthetic resin dry-type roofing material instead of the conventional wet-type roofing material consisting of clay, stucco, mortar, etc. (Japanese Unexamined Patent Publication No. Hei 10-292564) proposes a "ridge structure of a tiled roof" that enables ventilation of the roof.

[0003] The ridge structure described in the above publication is roughly described as follows.
The roof tile is supported by a ridge roofing material of a specific shape, and the back of the hut is opened to the interior space of the ridge roofing material by a ventilation opening provided at the ridge of the baseboard. It is composed of a main body on which the tile is placed, and a pair of leg-shaped sealing portions made of foamed resin for sealing a gap between the roof tiles on both sides in the width direction of the crown tile. The main body of the roofing material has a plurality of ventilation holes (openings) arranged along the longitudinal direction near the center in the width direction, and a ventilation path with a rising gradient from both sides in the width direction to the ventilation holes respectively. As well as baffles arranged in three rows in the left and right recesses, respectively. Moreover, the baffle plates in each row have a dividing function of forming a ventilation path in a zigzag shape.

[0004] In the above-mentioned ridge structure, the back of the hut communicates with the interior space of the ridge roofing material through a ventilation opening, and the interior space communicates with the outside through a sealing portion made of air-permeable foamed resin. In addition, it communicates with the outside through a plurality of ventilation holes of the main body and left and right ventilation paths (recesses). Therefore, in the above-mentioned ridge structure, the gap between the roof tile and the ground board and the back of the hut can be ventilated, and the ventilation passages on the left and right sides of the main body are formed with a rising gradient and zigzag by a plurality of baffle plates. Because it is configured in a shape, it is possible to control the infiltration of rainwater into the building.

[0005]

However, in the above-described ventilating ridge roofing material, the function of ventilating the inside of the ridge and the function of stopping water are originally contradictory functions. In the above roofing material, it is preferable to design the opening area and the ventilation area to be larger in order to improve ventilation performance. There is a demand for further improved means capable of reliably controlling the air blow. It is an object of the present invention to provide a roofing material having ventilation that allows ventilation of the back of a hut, which can further enhance the ventilation function and can more reliably prevent infiltration of rainwater into the building. To provide an improved wing roofing material.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a roofing material of the present invention is a synthetic resin breathable roofing material for supporting a roof tile of a tiled roof. A main body that is formed in an elongated flat box shape having a symmetrical vertical cross-sectional shape and that is arranged along the ridge in the longitudinal direction, and is formed in an elongated block shape and is formed at a lower portion on both sides in the width direction of the main body. The main body has a first opening for ventilation in the back of the cabin arranged in the vicinity of the center in the width direction along the longitudinal direction, and a longitudinal direction on both left and right sides in the width direction. And a second opening for outdoor opening arranged along the inside of the main body, and the inside of the main body is formed as a ventilation path with a downward slope from the first opening toward the second opening on each of the left and right sides. These ventilation paths are respectively formed on the inner wall of the ceiling of the main body and A plurality of baffles are protruded from the inner wall of the portion, and these baffles are sized to open the ventilation path with an opening area equal to or greater than the first opening, and When viewed superimposed on the basis of the ventilation path from the opening to the second opening, the ventilation paths are provided in a pattern complementary to each other so as to block the ventilation path.

In the above roofing material, since the plurality of baffles are provided in the ventilation path with a specific size and a specific pattern, the plurality of baffles are defined by the first opening, the ventilation path, and the second opening. When ventilating the inside of the building (behind the hut), a sufficient flow of air in the ventilation path is ensured, and a plurality of baffles capture rainwater blown by the crosswind by any of them.
