DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved tapered architectural plate which is suitable for constructing an outer enclosure such as a large dome-shaped roof and which can easily have a large radius of curvature. Related to the molding machine.

[0002]

2. Description of the Related Art Recently, outer enclosures such as roofs, walls and the like made of various metal folded plate type building plates have been constructed. In such an envelope, there are dome-shaped envelopes of various shapes such as a spherical shape and a cocoon shape. In the case of an enclosure composed of such special types of roofs, walls, and the like, it is not possible to construct the folded-plate-type architectural plate in a rectangular shape along the longitudinal direction.

Therefore, it is particularly preferable to use a substantially trapezoidal architectural plate in which both connecting bent portions are not parallel to each other but tapered along the longitudinal direction in plan view. The taper angle of the trapezoidal building plate is extremely small, but a large number of the trapezoidal building plates can form a dome roof of a large building (see FIG. 12).
Further, in order to make the dome roof spherical, the architectural plate needs to have a large radius of curvature along the longitudinal direction when viewed from the side.

[0004]

Therefore, a corrugated surface is formed along the longitudinal direction on the main plate of the above-mentioned tapered folded-plate building plate, and a curved shape is formed through the corrugated surface. ing. That is, in order to bend the folded architectural plate having a tapered shape in the longitudinal direction including the bottom portion and the rising side portions located on both sides in the width direction, the forming feed direction of the roll forming machine, It is necessary to match the taper angles of both sides in the width direction of the bottom of the tapered plate. Further, such an apparatus has various disadvantages such as an extremely complicated and expensive apparatus and an increase in facility load.

[0005]

Means for Solving the Problems Accordingly, the inventor of the present invention has conducted intensive studies to solve the above-mentioned problems, and as a result, the present invention
A large rising slope side portion is formed on both widthwise sides of the tapered bottom main plate having different widths at both ends in the longitudinal direction, and a connection bending portion is formed at an upper end of the large rising slope side portion, and the bottom main plate and the large rising slope are formed. At the corners with the sides, between the corners of the bottom main plate including the corners, the bottom main plate is separated on both sides in the width direction at a wide portion in the width direction of the bottom main plate. A tapered metal sheet formed by forming a substantially continuous corrugated surface at the center in the width direction and forming a curved tapered building plate formed by bending to a relatively large curvature when viewed from the side and a forming machine therefor. Thus, it is possible to easily and quickly form a tapered architectural plate, and the above-mentioned problem is solved.
