PANEL OF PROGRESSIVE SHUTTERING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to civil and industrial construction activities and particularly to design of progressive shuttering panels used in concrete work. In panel of progressive shuttering, framework is made with holes for passing of mounting loops. Mounting loops are created by lengths of rope having devices for returning loops to idle position by way of displacing into holes of framework. Device for returning mounting loops to idle position can be made in the form of weights rigidly fastened on free ends of rope which are inserted through holes inside framework. At least part of ropes can be made in the form of enclosed loops, and device for returning mounting loops to idle position is made in the form of counterweights secured on rope with possible displacement along rope. Device for returning mounting loops to idle position can also be made in the form of resilient member installed at least on one end of rope. Framework is made from profile stock of box cross-section. Edges of holes in framework are located at distance ensuring that there is no contact between edges of holes and rope when loops are in working position. Panel of progressive shuttering can be provided with additional ropes installed in framework with location of mounting loops created by them parallel to main ropes and made in the form of enclosed loops preferably with displacement limiters movable along length of rope, or in the form of rope with displacement limiters on ends of rope. Distance between displacement limiters of additional ropes is not less than working length of main mounting loop. Aforesaid embodiment of progressive shuttering panel allows for increasing tempo of working operations, reducing labour-intensity, and improving repairability of equipment. EFFECT: higher efficiency. 5 cl, 4 dwg
