Permanent formwork of bridge deck of multi-girder steel mixing structure bridge
The invention discloses a permanent formwork of a bridge deck of a multi-girder steel mixing structure bridge. Corrugated steel plates are adopted; the bridge deck is supported by multiple steel longitudinal beams; the corrugated steel plates are located at the bottom of the bridge deck and erected between every two adjacent steel longitudinal beams; the two ends of each corrugated steel plate are correspondingly connected with the adjacent two steel longitudinal beams through two steel angles; one sides of connecting angles are welded to the ends of side faces of the upper flanges of the steel longitudinal beams through fillet welds; the crests of the ends of the corrugated steel plates are flattened and then are connected with steel angle horizontal flange plates through tapping screws; the corrugated steel plates are transversely in lap joint by half bandwidth and are connected through tapping screws. The permanent formwork can achieve the safe, superior, rapid, economical and durable purposes of construction of the cast-in-place concrete bridge deck of the steel mixing combined structure bridge.
