COMBINED STRUCTURE OF COVER Russian patent published in 2010 - IPC E04C3/29 

FIELD: construction.

SUBSTANCE: combined structure of cover consists of upper belt, broken lower belt and grid braces. Upper belt is made with inverted-V contour and is formed with two beams, which are hingedly connected to each other in ridge. Lower belt consists of support, intermediate and ridge branches. Lower belt hingedly adjoins ends of upper belt. Grid braces are hingedly coupled with upper and lower belts. Grid comprises two support, two ridge and two intermediate braces. Lower belt has billowed contour, when ratio of structure span to height of upper belt lift in ridge makes from 4 to 6 with inner sharp angles between upper belt and grid braces, and also support branches of lower belt, making from 30° to 50°. Intermediate branches of lower belt are arranged in parallel to upper belt. Ridge branch of lower belt connects units of ridge and intermediate braces coupling to each other and has horizontal orientation.

EFFECT: increased useful volume of covered premise and simplified structural scheme of cover.
