Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a construction method for a curved part of a building such as a dome, in which face plates are sequentially connected to form a curved outer wall surface of a building such as a dome.

<Prior Art> As is well known, the roof of a building has a hemispherical dome. Therefore, when this dome is constructed with a metal face plate, the dome is divided into small sections, and the top and bottom sides are approximately parallel to each other, and the left and right sides are slightly parallel to each other. A large number of face plates are formed which are slanted toward the end, and each face plate is provided with an engaging portion or a connecting portion at its periphery, and the above-mentioned face plate is fixed to a supporting member attached to the frame of the dome using a hanger or the like. The dome is formed by connecting the adjacent face plates vertically, horizontally, and horizontally.

<Problems to be solved by the invention> However, in the conventional construction method for curved parts using finely divided face plates, the shape and size of the face plate must be determined according to the curvature of the outer wall surface of the building. First, it is necessary to prepare a large number of face plates specifically for the building that match the design of the building, so it takes time to create the face plates, and it also takes time to lay them, which ultimately increases the construction cost. Furthermore, if a roughly divided face plate is used, the curved surface will be rough and the face plates cannot be connected smoothly. On the other hand, when the curved surface is constructed from subdivided face plates, a smooth curved surface can be obtained, but the construction requires an extremely large amount of work, prolongs the construction period, and increases construction costs such as labor costs. . Furthermore, since the number of connection points increases with the subdivided face plate, not only is it time-consuming, but the risk of rainwater entering from the connection points increases, making it impossible to obtain a sufficient rain protection effect.

<Means for solving the problems> The present invention has been proposed in view of the above, and includes forming a plurality of folded bent portions in the width direction in advance, and
A face plate with a first engaging part bent on either the upper edge or the lower edge is bent at the construction site to correspond to the curvature of the building, and the other edge of the face plate is bent. A second engaging portion that can be engaged with a first engaging portion formed on an adjacent face plate is bent.
The engaging portion and the first engaging portion are engaged to sequentially connect vertically adjacent face plates, and horizontally adjacent face plates are connected to each other to form a curved surface.

<Function> By re-bending the bent part provided in the width direction of the face plate at the construction site, the lengths of the upper and lower edges of the face plate can be changed to match the curvature of the building. The face plates can be connected to each other by engaging the first engaging portion provided and the second engaging portion provided on the other edge.

<Example> Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings.The present invention applies a dome 2, etc., in which a face plate 1 prepared in advance at a factory is subjected to simple processing at a construction site, and the face plate 1 is sequentially connected and installed.
