DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved building plate which can be installed at a desired position on a building structure while maintaining a long building plate curved in a longitudinal direction with a desired radius of curvature. The present invention relates to an apparatus for supporting construction of a building plate and a construction method thereof.

2. Description of the Related Art In recent years, large-scale architectural structures having roofs, walls, and the like in which various arc-shaped surfaces or spherical surfaces having different radii of curvature are assembled have been constructed (see FIG. 14). Such an enclosure surrounds and fixes a plurality of long architectural boards to structural materials such as a purlin and a rim, but the architectural boards are not bilaterally symmetrical and substantially hyperbolic, but have a curved shape. The radius of curvature in the longitudinal direction of the architectural plate arranged at each position varies variously and slightly depending on the shape of the outer enclosure. Therefore, there are curved portions having different radii of curvature in the longitudinal direction of the building plate.

[0003]

In the construction of such an envelope such as a roof or a wall of a building structure, when a building plate curved in a longitudinal direction is formed by a roll forming machine, a roll forming machine is used. In order to form a curved architectural plate from a metal coil material with a machine, the curved architectural plate sent out from the roll forming machine is desirably maintained on the ground while following the curve. It is necessary to support at a predetermined position in the longitudinal direction of the building plate until the length becomes.

[0004] Workers support this architectural plate. That is, the workers are respectively arranged at different positions in the height direction on temporary scaffolds provided around the building structure, and each worker has supported the building plate with their own hands and arms. For this purpose, a plurality of workers are arranged in the direction in which the curved architectural plate is sent out while the curved architectural plate is formed by a roll forming machine. Then, the worker has to move the building board in the sending direction while maintaining the building board at his / her place at a predetermined height by hand.

[0005] This operation requires a large number of workers along the longitudinal direction of the curved building board. In addition, each worker must move the building plate in the delivery direction while supporting the curved building plate at his or her own yard.
For that purpose, it is necessary to collect a large number of workers, and in addition to this, a heavy labor burden is imposed on the workers. In addition, the labor burden on the workers adversely affects the accurate molding of the curved building plate and the maintenance of the curved shape, and as a result, the accuracy after the molding of the curved building plate is greatly deviated. It could be.

[0006]

The inventor of the present invention has made intensive studies to solve the above-mentioned problems.
