PRESTRESSED STRUTTED COVERING Russian patent published in 2003 - IPC

FIELD: construction industry, design and manufacture of spatial prestressed constructions of coverings for factory and civil buildings and structures. SUBSTANCE: prestressed strutted covering is made up of plates possessing holes of rectangular form, blockouts, posts fitted with bearing members in the form of rectangular plates and joining beams. In process of mounting of plates on posts axial force is applied in vertical direction due to which force of preliminary stress emerges in joining beams. In this case posts are displaced by distance Δ downwards and bearing members in the form of rectangular plates come out of rectangular holes of plates variable in height. Then bearing members turn to position parallel to short side of plates and are attached to blockouts. After it axial force stops to affect them. After mounting of adjacent plates of covering bearing members are interjoined forming lateral bearing constructions after mounting of all plates of covering and covering functions as single spatial structure with prestressed members. EFFECT: reduced usage of materials. 4 dwg
