Description
Technical field
The utility model relates to bridge structure technical fields, combine in particular to a kind of novel longitudinal rib inversion type railway steel reinforced concrete
Bridge deck structure.
Background technique
Bridge deck structure is the key position of Bridge Design, and floorings directly take on bridge floor mobile load, and the load of receiving is passed
Girder is passed, the design of bridge deck structure is the key that bridge structure design, is directly related to stress performance, the construction investment of structure
And structure durability.
It is two kinds of concrete bridge deck system and Steel Bridge Deck system that railway deck system, which uses at most, at present, while creating part railway
Cable-stayed bridge also uses the bridge deck structure of steel reinforced concrete bondbeam or composite beam.
Concrete bridge deck system simple structure, overall stiffness is big, and driving condition is good, but larger due to being self-possessed, and the later period shrinks Xu
Become and be difficult to control, generally in the end bay of medium and small bridge and Large Span Bridges using more.
Steel Bridge Deck system has many advantages, such as strong, applied widely from heavy and light, span ability, is chiefly used in long span stayed-cable bridge, outstanding
Cable bridge, steel truss arched bridge, but conventional orthogonal opposite sex steel bridge deck vertical, horizontal weld seam is more and stress is complicated, steel bridge deck rigidity compared with
Small, fatigue problem is more prominent, and late maintaining maintenance load is big.
The bridge deck structure of steel reinforced concrete bondbeam or composite beam is often not provided with transverse seal steel top plate, girder steel construction part
The shearing force between faying face is transmitted by setting WELDING STUDS between concrete slab.Such bridge deck structure needs to be arranged thick
Thicker floorings are spent to meet structure entirety stress, and hogging moment controls concrete slab design, generally requires to arrange more
Longitudinal prestressing to meet concrete slab demand of anti-crack, it is difficult that Longspan Bridge concrete slab is designed and is constructed
It spends larger.
