Roof large cantilever type steel support frame high formwork structure

Abstract

The utility model relates to a kind of high formwork structure of roof large cantilever section steel support frame, including the first cantilever girder being set on top floor level and protruding and the second cantilever girder being set on the layer level below top floor and protruding, first cantilever girder outer end is pulled and connected on roof beam board wall column concrete by steel wire rope, second cantilever girder outer end is supported first cantilever girder by truss structure oblique support component;Second cantilever girder outer end is supported second layer level below top floor by lower inclined brace oblique support.In the two cantilever girders between using I-beam structure truss oblique support reinforcement, combined with the second cantilever girder below using lower inclined brace support reinforcement, overall structure reinforcement support stability, firm, cooperate on cantilever girder using opening cooperation connecting plate full-welding support connection, convenient high-altitude welding operation in site while improving welding connection strength, improve support stability.
