Bridge deck unit without transverse surface tensioned joints, bridge structure without transverse surface tensioned joints and construction method of bridge structure
The invention discloses a bridge deck unit without transverse surface tensioned joints. The bridge deck unit is mainly formed by integral prefabrication of diaphragm plates and a bridge deck slab. Upper flanges of the diaphragm plates are pre-embedded in the bridge deck slab, and the upper sides of the upper flanges are free of the transverse surface tensioned joints; a latticed thin plate provided with longitudinal ribs and transverse ribs is selected as the bridge deck slab, and two sides of the bridge deck slab are set to be connection portions and extend outwardly to form connection rebars. At least two bridge deck units, lower webs and longitudinal bridge steel beams are connected to from a bridge structure without the transverse surface tensioned joints, wherein the lower webs and the longitudinal bridge steel beams are positioned on the lower portions of the bridge deck units, and cast-in-situ joints are arranged on the upper sides of upper flanges of the longitudinal bridge steel beams; the connection rebars of every two adjacent bridge deck units are bound at the cast-in-situ joints. A construction method includes welding longitudinal bridge steel beam segments, welding shearing-force nails, erecting prefabricated bridge deck slab construction formworks, prefabricating the bridge deck units through casting, lifting the bridge deck units to the steel beam segments, welding the diaphragm plates and finally, casting the joints in situ to complete construction. The bridge deck unit has the advantages of light dead weight, high durability, good stress performance, low cost and the like.
