[0002]

2. Description of the Related Art Conventionally, in this kind of thatched roof,
For example, Japanese Patent Publication No. 3-48984 and Japanese Patent Publication No. 3-489.
As disclosed in Japanese Patent Application Publication No. 85 or Japanese Patent Publication No. 3-63621, a cap member is provided between compatible rising portions of adjacent roof plate main bodies laid on a base material, and the cap member is used for roofing. One in which the rising portions of the plate main bodies are tightened with a gobet, or they are fitted together to raise the roof, and as disclosed in Japanese Patent Laid-Open No. 63-251562, face plate portions of adjacent roof plate main bodies are connected to each other. There is one having a configuration in which it is directly pressed.

[0003]

However, in the structure of such a conventional thatched roof, in the case of the former,
By holding the upper end side of the rising part of the roof plate main body with the cap member and making the contact parts higher than the face plate part of the roof plate main body, rainwater flowing on the face plate part of the roof plate main body can be provided in case of rain. Although it is intended to prevent invasion from the contact portion, this causes insufficient holding strength of the rising portion of the roof plate main body by the cap member against wind pressure,
Since the rising portion of the roof plate main body is weak against the tensile force, the roof plate main body is easily deformed, and the face plate portion of the roof plate main body is lifted up.

In the latter case, in which the face plate portion of the roof plate body is directly pressed by the connecting member, the contact portion of the connecting member is on the face plate portion of the roof plate body, so In some cases, rainwater flowing on the face plate portion of the roof plate body easily intrudes from the contact portions due to the capillary phenomenon, resulting in poor rain performance.

Further, in order to prevent rainwater from entering due to such a capillary phenomenon, even if a decompression space is provided at the contact portion between the face plate portion of the roof plate main body and the connecting member, sand, dust, etc. at the contact portion. When the foreign matter of the above is clogged, the foreign matter may inhale the rainwater, so that it is inevitable that the rainwater will infiltrate into the connection part, which causes corrosion of each component in the connection part and durability. There was a problem of being damaged.

[0006]

An object of the present invention is to improve the durability by increasing the holding strength of the rising portion of the roof plate main body against wind pressure and by reliably preventing the intrusion of rainwater due to the capillary phenomenon at the connection site. (EN) Provided is a vertically-roofed roof structure and its construction method.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a base material and a base material, which are laid adjacent to each other on the base material, and which are vertically arranged on both side edges of the face plate portion. A roof board main body in which a rising portion having a height of is bent and formed, and a lower suspension fixed between the roof board main bodies fixed to the base material.

In a vertically-roofed roof having a protective cover that protects between the compatible rising parts between the respective roof plate bodies, in the compatible rising part of the roof plate body, about the total height of the vertical rising parts from the face plate part The stepped portion held by the lower suspension and the upper suspension is bent outward at a position of 1/3 or less and 8 mm or more.

[0008]

That is, according to the present invention, by adopting the above-mentioned configuration, since the step portion bent and formed at the rising portion of the roof plate main body is set at a position 8 mm or more from the face plate portion, The holding part between the suspension and the upper suspension is higher than the draft position of the rainwater flowing through the face plate part of the roof plate body in the case of rain, etc., which allows rainwater to infiltrate due to the capillary phenomenon at the conventional connection part. Certainly prevented.

Further, since the step portion bent and formed on the rising portion of the roof plate main body is provided at a position of about 1/3 or less and 8 mm or more of the entire height of the rising portion in the vertical direction from the face plate portion. In addition, the holding part between the lower suspension and the upper suspension is located at a position lower on the face plate side than the upper end side of the rising part of the roof plate body as in the past, and the rising part of the roof plate body is pulled by wind force. Become stronger against.

Further, a step portion, which is formed by bending outward toward the outer side of the roof plate main body, is formed on the lower suspension in a state of holding the lower suspension and the upper suspension. Since it is clamped by the holding part formed on the upper suspension corresponding to the section, the holding strength of the rising part of the roof plate main body against wind pressure is enhanced, and thus the rising part of the roof plate main body becomes a tensile force. In contrast, the face plate portion is not lifted up due to the deformation of the rising portion of the roof plate body as in the past.
