APPARATUS FOR MANUFACTURE OF FERROCONCRETE PRODUCTS WITH CURVED SURFACE Russian patent published in 1999 - IPC

FIELD: construction industry, in particular, fabrication of multilayer members of warmed covers and outer walls of buildings and constructions. SUBSTANCE: apparatus has flexible pan with detachable sides manufactured from resilient material, stationary and movable bed members interconnected by hinge joint and connecting beams. Fixed members of bed are mounted on framework. Pan is attached with its central part to bed members along hinge joint. Movable members of bed are lifted by means of jacks or other lifting mechanisms engageable with connecting beams, with following mounting of tie-bars. Apparatus allows wide range of thin-walled members having different curvature patterns to be produced. EFFECT: wider operational capabilities and enhanced reliability in operation. 4 cl, 6 dwg
