PROGRESSIVE SHUTTERING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: progressive shuttering is used for erection of walls from concrete blocks. Shuttering has two identical modules, displacing panel, and lateral shield. Each module is made up of two longitudinal shields which are fixed relative to each other by means of two U-shaped frames. Also included are at least two hollow-core forming mandrels which are installed between longitudinal panels and can be removed. In each module, hollow-core forming mandrels are fixed relative to each other by means of lateral pins, and hollow-core forming mandrels are fixed relative to longitudinal shields by means of T-shaped handle. T-shaped handle is installed on each hollow-core forming mandrel in center of its upper base with possibility of its turning to position at which ends of its horizontal cross-member rests against longitudinal shields. Lateral shield is made as removable. Displacing panel is made with openings for passing of hollow-core forming mandrels. U-shaped frames are provided with members which protrude above longitudinal shields. These protruding members create handles for replacement of module. Application of aforesaid embodiment of progressive shuttering affords convenience in usage which reduces labour-intensity in erection of walls. EFFECT: higher efficiency. 3 cl, 5 dwg
