Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof plate structure for a curved roof, and more specifically to a building whose roof surface is formed of a curved surface such as a conical shape, a dome shape, a curved dome shape, etc. The present invention relates to the structure of a metal roof sheet suitable for forming a roof.

[Prior Art] As a roof structure for a building, a metal roof is known in which copper plates and steel plates formed into several types of predetermined shapes are prepared and these are combined.

Many proposals have been made regarding the form and structure of metal roofs, and in recent years there have been many types of roofs on buildings (such as conical, dome-shaped, and curved roofs, which have become popular). Many proposals have also been made regarding metal roof panels to be attached to curved roofs.

[Problem to be solved by the invention] However, as a metal roof structure for forming the above-mentioned curved roof, a curved roof was formed by simply laminating thin metal flat plates processed into curved surfaces. However, it was difficult to install it with nails, etc., which were exposed on the surface and spoiled the appearance, and it was also difficult to obtain sufficient watertightness.

Therefore, in order to install it, it is necessary to set the shape of the roof sheet in consideration of its properties, appearance, and watertightness, but it is extremely difficult to process a roof sheet that satisfies these conditions. In order to accurately process a roof plate having a curved surface and a predetermined connection shape, an expensive high-precision processing machine is required. As a result, processing equipment costs, running costs, etc. have increased, and the manufacturing cost of the roof panels has increased, making the pole curved roof expensive.

Particularly in the case of a roof that is raised from the bottom upwards, if the shape of the lower edge of the roof plate is not accurate enough to cover the upper edge of the lower roof plate, it will not only be difficult to install. Since this causes a decrease in watertightness, it is necessary to process it with high accuracy using a high-precision processing machine, and its installation is also troublesome, causing an increase in both manufacturing and installation costs.

Therefore, the present invention has developed a curved roof that does not require special processing machinery, can be manufactured at low cost, can be easily attached to the roof surface of a building, and has excellent performance such as rough watertightness. The purpose is to provide roof shingle structures for

[Means for Solving the Problems 1] In order to achieve the above object, the present invention provides a roof plate having a sloped surface portion formed in a predetermined curved surface and a hanging side formed by bending the lower edge of the sloped surface portion downward. It has a main body, an engagement groove that engages with the hanging side of the roof shingle main body, and a rigid side portion that extends from the lower part of the engagement groove toward the back surface of the roof shingle main body, The present invention provides a roof shingle structure for a curved roof, in which an edge member is formed with a curvature corresponding to the edge, and roughly the hanging side of the roof shingle body has an edge member formed with a curvature corresponding to the edge.
An elastic claw portion that comes into contact with the inner wall of the engagement groove of the edge member is completely formed, and/or an upper portion of the engagement groove of the edge member on the back side of the roof plate body has a hanging edge of the roof plate body. This includes those characterized by forming an elastic side portion that comes into contact with the back surface.

[Function] By configuring the roof board as described above, the main body of the roof board can be formed by processing the metal plate into a predetermined curved surface and engaging the lower edge of the roof board on the negative side of the roof board. It can be integrated with the board body. Then, to create a roof board that combines both, the fixed side part of the edge member is overlapped with the upper part of the lower roof board, and this overlapping part is fixed to the roof base material with a hanger member, etc., so that the roof surface of the building Can be installed on.

Roughly, on the hanging side of the roof shingle main body, an elastic claw that contacts the inner wall of the engagement groove of the edge member, and/or on the upper edge of the engagement groove of the edge member on the back side of the roof shingle main body, the roof shingle main body. By forming the elastic side portion that comes into contact with the back surface of the hanging side, the hanging side and the engagement groove can be elastically engaged, and the two can be reliably integrated.

It can be processed to form various shapes. Furthermore, the edge member can be easily formed by processing a narrow metal plate. Roughly, this edge member can be formed by inserting the hanging side of the roof board main body into the retaining groove, and the elastic side can be easily formed by bending the edge member in advance before processing the groove.
