Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a curved roof structure, and in detail, the roof surface is formed of a curved surface, such as a conical roof, a dome-shaped roof, and even a curved roof. This is related to the roof structure.

(Prior Art and Problems to be Solved) Various types of roof structures have been proposed for buildings, and the material for the roof structure is a steel plate made by bending a thin steel plate into a predetermined shape. Manufactured roof shingles are widely used.

By the way, when constructing a curved roof formed by a curved surface, such as a conical roof, a dome-shaped roof, or even a curved roof, which have recently become popular as roof types for buildings, using steel roof sheet materials, If a curved roof is simply formed by laminating flat roof panels made into curved surfaces, the fixing nails of each roof panel will be exposed on the surface, which is unfavorable in terms of appearance, and it is difficult to obtain sufficient watertightness. Furthermore, in order to process a flat plate into a curved shape to solve these problems, a high-precision processing machine is required, which increases manufacturing costs.

For example, as shown in FIG. A roof structure has been proposed that includes a groove 5 that engages the hanging piece 1 and an edge member 9 having a fixing piece 7 (Japanese Patent Laid-Open No. 2-176054).

However, in this roof structure, since the hanging piece 1 of the roof plate body 3 and the engagement groove 5 of the edge member 9 are vertically engaged, there is a problem in terms of shutting down the rain. There are problems that need to be improved, such as insufficient fixation between the upper roof plate main body 3a and the lower roof plate main body 3b, which poses problems in terms of strength.

[Means for solving problems]

Therefore, in this invention, in a curved roof structure constructed by attaching an edge member to both edges of a roof plate body whose upper and lower edges are formed with a predetermined curvature in accordance with the shape of a curved roof, the lower part of the roof plate body is provided. The edge is folded back in the lower horizontal direction to form an insertion part, and the upper edge is bent upward in a substantially vertical direction and then folded back in the horizontal direction to form an engaging part. An insertion groove is formed by folding a substantially vertical side door portion formed to a predetermined curvature and the upper end of this side door approximately horizontally, and inserting the insertion portion of the roof board body installed on the upper level into the insertion groove of the edge member. By inserting and fixing the edge member and the roof plate body to the roof body via the hanger member inscribed in the door portion of the edge member, sufficient watertightness is ensured and the strength is increased. It is.

In this case, if a slip prevention piece is formed at the end of the hanger member inscribed in the side door part of the edge member and this slip prevention piece is made to face the engagement piece of the roof board body installed on the lower level, It is possible to prevent displacement of the installed roof shingles as much as possible, and furthermore, by forming downward ridges on the left and right edges of the roof shingle body, the lower ridges of the adjacent roof shingles can be prevented from moving. It is preferable to connect it to the receiving member by tightening it.
