Title:
CORRUGATED METAL BUILDING PANEL
Document Type and Number:
Japanese Patent JPS56125553
Kind Code:
A
Abstract:
A corrugated metal building panel (20, 120, 320, 420) (e.g., made of steel) is provided herein. The panel has at least one (321) (and preferably two, 21-22, 121-122, 421-422) longitudinally extending major waves. Each such major wave is provided with longitudinally extending minor corrugations (26, 126, 326, 426) superposed on each major wave (21-22, 121-122, 321, 421-422) and following the general corrugated pattern of the panel (20, 120, 320, 420). The longitudinally extending minor corrugations (26, 126, 326, 426) are constituted by a plurality of spaced-apart, discontinuous, longitudinally extending stiffeners (28, 128, 328, 428) superposed thereon. The stiffeners (28, 128, 328, 428) follow the general major corrugated pattern of the panel. The spaces between the stiffeners include flattened portions (27, 127, 327, 427) of the general major corrugated pattern of the panel but in a preferred variant, also include some corrugated portions (26, 126) interspersed between the flattened portions. Furthermore, the stiffeners (28, 128, 328, 428), which are distributed along the major wave (21-22, 121-122, 321, 421-422), always project from the exterior of the curvature of the major wave (21-22, 121-122, 321, 421-422).
