Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically-roofed roof structure in which a roof plate made of a metal steel plate is laid on the lower ground of a building, and a construction method thereof.

[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.
Such as disclosed in 85 JP or Laid equitable 3-63621 discloses, the cap member is provided between both upward portion of the adjacent shingle body laid on a base material, in the cap member The roof board main body is tightened with a gobet, or is fitted and roofed, or
As disclosed in Open Sho 63-251562 discloses, those having a direct pressing and formed by constituting the face plate of the adjacent shingle body at a connection member.

[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.
An upper suspension which is engaged with the lower suspension and which holds and joins the compatible rising portions of the roof plate main bodies which are adjacent to and face each other with the lower suspension, and is fitted to the outer periphery of the upper suspension. And a protective cover for protecting between the compatible rising portions between the roof plate main bodies, wherein the compatible rising portion of the roof plate main body is approximately 1 / of the entire height of the vertical rising portion from the face plate portion. A step portion is bent outwardly at a position of 3 or less and 8 mm or more, and the lower suspension is formed on the base portion which is placed and fixed on the base and the base portion. While having a held portion with which the upper suspension is engaged and a shoulder portion that is formed to extend outside the held portion, the upper suspension is fitted so as to cover the upper surface of the lower suspension. The fitting surface part to be engaged and the back side of the fitting surface part are engaged with the held part of the lower suspension. And a holding portion formed corresponding to the shoulder portion of the lower suspension outside the holding portion and at the lower end of the fitting surface portion, and between the roof plate main bodies. It is characterized in that the stepped portion formed in the compatibility raising portion is held between the shoulder portion of the lower suspension and the holding portion of the upper suspension.

[0008]

That is, according to the present invention, by adopting the above-mentioned structure, the step portion formed by bending the roof board main body toward the outside is formed in the upwardly compatible portion in the holding state of the lower suspension and the upper suspension, Since it is sandwiched between the shoulder portion formed on the lower suspension and the pressing portion formed on the upper suspension so as to correspond to this shoulder portion, the holding strength of the rising portion of the roof plate main body against wind pressure is increased, As a result, the rising portion of the roof plate main body becomes stronger against the tensile force, and the face plate portion is not lifted up due to the deformation of the rising portion of the roof plate main body.

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.

Moreover, 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 portion held between the lower suspension and the upper suspension is rainy. It is higher than the draft position of the rainwater flowing through the face plate portion of the roof plate body at times, etc., whereby the intrusion of rainwater due to the capillary phenomenon at the conventional connection site is reliably prevented.

[0033]

As is apparent from the above description, according to the present invention, a step portion, which is formed by bending outward toward the outer side of the roof plate main body, is formed in the engaged state of the lower suspension and the upper suspension. , Since it is sandwiched between the shoulder portion that is formed on the lower suspension and the pressing portion that is formed on the upper suspension so as to correspond to this shoulder portion, the holding strength of the rising portion of the roof plate body against wind pressure is increased. As a result, the rising portion of the roof plate main body can be made stronger against the tensile force, and the face plate portion is not lifted up due to the deformation of the rising portion of the roof plate main body.

Further, the step portion formed by bending at the rising portion of the roof plate main body is provided at a position not more than about 1/3 of the overall height of the rising portion in the vertical direction from the face plate portion and not less than 8 mm. From here, the holding part by the lower suspension and the upper suspension,
It is located at a lower position on the face plate portion side than the upper end side of the rising portion of the roof plate body as in the past, and thereby the rising portion of the roof plate body becomes stronger against the tensile force due to wind pressure.

Moreover, since the step formed by bending the rising portion of the roof plate body is set at a position of 8 mm or more from the face plate portion, the sandwiched portion by the lower suspension and the upper suspension is provided in the rain. Since it can be set higher than the draft position of the rainwater flowing through the face plate of the roof plate body at times, it is possible to reliably prevent rainwater from entering due to the capillary phenomenon at the connection site as before, and durability Can be improved.
