PREFABRICATED PANEL OF FOLD FORM Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: prefabricated panel of fold form is made of bent shape with trapezoidal form of corrugations and transverse V-shaped cut-outs, that correspond to corners of framing and do not touch outside seats. Shape is bent so, that its cut areas match and join each other. To simplify production, increase stability and expand operational capabilities to attach additional members, corrugations are cut by intercrossing transverse and longitudinal cuttings, made along corrugations ribs to ribs, adjacent to outer seats. V-shaped cut-outs are made by inside or outside bendings of areas of рplanes, cut by lines, connecting peaks of cuttings. Shape bending is made along transverse cutting up to corresponding bendings match and rigidly join each other. Bendings of prefabricated panel have coaxial holes to join each other and to fix additional members. Prefabricated panel is distinguished by the fact, that connecting gaskets are placed between bendings and fixed. Gaskets free areas have holes, through which prestressed cables, connected with supporting sections of panel, are passing. Besides, at least one of panel butts has facing inside slope, formed due to cuttings of ribs, adjacent to inner seats, and to bendings of corrugations planes edges toward inside along lines, that connect peaks of cuttings to each other and with end points of ribs, adjacent to outer seats. Shape outside located bendings are rigidly joined and form transverse diaphragm of rigidity. To simplify piling and transportation bendings are rigidly fixed to corrugations planes by overlapping. In the case, bendings, located outside, are referred to the parts of shape, that have smaller angle of inclination to horizon in places of cover axis breaking. Bendings of panel end sections edges are rigidly connected to each other and are forming polygonal closed ring. EFFECT: prefabricated panel is used in erection of skeletonless prefabricated small and middle span buildings of different use. 7 cl, 7 dwg
