LONG-MEASURED BUILDING CONSTRUCTION OF SUPPORT POST TYPE OF ELECTRIC POWER LINE Russian patent published in 1994 - IPC

FIELD: building constructions. SUBSTANCE: construction has sheet elements connected together and curved in their cross-section. The elements are made to have longitudinal corrugations 2 and 3. Half corrugations is turned with their vertexes relatively axis of symmetry of sheet element against center of curvature of sheet element of sheet element against center of of corrugations has the form to correspond to forms of corrugations mentioned above from the side of the second end of sheet element and is turned with their vertexes to center of curvature of sheet profile. Axes of symmetry of any corrugation are aligned with radius-vector, which is oriented from center of curvature of the profile at an angle to straight line which crosses center of profile arc and across center of curvature. The relation which determines location of corrugations is given in the description of the invention. EFFECT: reduced labour input; widened area of application. 4 dwg
