Abstract
The invention belongs to the technical field of bridge engineering and relates to a connector-free steel and ultrahigh-performance concrete combined bridge deck structure and a construction method thereof. The bridge deck structure comprises a steel bridge deck slab, a bridge deck pavement layer is paved on an ultrahigh-performance concrete layer which is paved on the steel bridge deck slab; the upper surface of the steel bridge deck slab is provided with protruding lines, and the lower portion of the steel bridge slab is provided with longitudinal stiffening ribs and transverse stiffening ribs.

Compared with a traditional orthotropic steel bridge deck structure, the connector-free steel and ultrahigh-performance concrete combined bridge deck structure has the advantage that technical problems of fatigue rupture of steel structures and proneness to damages of the pavement layers can be effectively solved according to the scheme. Moreover, the connector-free steel and ultrahigh-performance concrete combined bridge deck structure has the advantages of convenience in material acquisition, structural simplicity, quickness in construction, force reasonability and high technical and economical benefits.
Description
Technical field
The present invention relates to a kind of combined bridge deck structure being applied to Loads of Long-span Bridges bridge deck, belong to bridge engineering field.
Background technology
After World War II, Germany is the bridge recovering to be damaged by war, uses Orthotropic Steel Bridge Deck in a large number.Subsequently, due to the application of the improvement of structure analysis method, the raising of solder technology and high-strength steel, the Design and manufacture of steel bridge deck becomes ripe, and orthotropic steel bridge deck is used widely in many countries.The application of the orthogonal profile iron bridge deck of China starts from the eighties in 20th century, starts large-scale use, and developed rapidly to the nineties.
But, there are two large technical barriers: steel work easily occurs fatigue crack in Orthotropic Steel Bridge Deck complex structure, paving steel bridge deck very easily damages simultaneously.For this two large technical barrier, more domestic scholars propose the new approaches solving this problem, namely use steel-very-high performance combined bridge deck structure.Ultra-high performance concrete is applied on Steel Bridge Deck, to reduce the thickness of layer of concrete, reduces bridge deck weight, and significantly improve the durability of bridge deck.But this kind of combined bridge deck structure usually adopts tradition weldering to follow closely connector and resists steel plate-concrete interface shear stress, and connector welding job amount is very large, and bridge deck structure construction is loaded down with trivial details, reinforcing bar binding difficulty, and following long-time maintenance is larger with reparation difficulty.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide a kind of steel plate-ultra-high performance concrete without connector combined bridge deck structure, on orthotropic steel bridge deck without connector combined bridge deck scheme.This structure is by arranging protruding pattern at bridge deck upper surface, reach the object of Shear connection and Transfer of Shear, the technical barriers such as the shear connector welding job amount that solution conventional steel-very-high performance combined bridge deck structure exists is large, construction technology is loaded down with trivial details, reparation difficulty is large.
Ultra-high performance concrete is made up of RPC and steel fibre, is a kind of cement-base composite material with superhigh intensity, superhigh tenacity and high-durability.
A kind of steel-ultra-high performance concrete of the present invention is without connector combined bridge deck structure, and it is characterized in that, this bridge deck structure comprises steel bridge deck, and ultra-high performance concrete layer is laid in top, lays bridge deck pavement above ultra-high performance concrete layer; Described steel bridge deck upper surface is with protruding pattern, and described steel bridge deck bottom is provided with longitudinal stiffener and transverse stiffener.
Described ultra-high performance concrete layer is built by ultra-high performance concrete and is formed, and is wherein provided with reinforcing bar.
Described ultra-high performance concrete layer and the bonding surface of bridge deck pavement are nature matsurface.
Steel-ultra-high performance concrete of the present invention is without the construction method of connector combined bridge deck structure, and it is characterized in that, the method comprises the following steps:
(1) prefabrication riffled iron bridge deck;
(2) by the steel work part steel bridge deck of conventional orthogonal opposite sex Steel Bridge Deck welding procedure welding combined bridge deck structure, longitudinal stiffener and transverse stiffener;
(3) on steel bridge deck, ultra-high performance concrete is built;
(4) asphalt concrete material is layed on the good ultra-high performance concrete layer of maintenance and namely completes construction.
Can reinforcing bar in first colligation ultra-high performance concrete layer in said method, then build ultra-high performance concrete.
The present invention has following beneficial effect relative to prior art:
(1) because steel bridge deck protruding pattern provides required Shear connection, its top does not need to arrange weldering nail shear connector again.(2) relative to existing steel-ultra-high performance concrete combined bridge deck structure, the present invention can avoid a large amount of shear connector welding.Because bridge deck structure top is without shear connector, the difficulty of construction of bridge floor assembling reinforcement also reduces greatly.(3) adopt the dismounting operation that simultaneously can simplify bridge floor top ultra-high performance concrete layer without connector scheme, thus reduce the reparation difficulty of combined bridge deck.(4) compare traditional Orthotropic steel bridge deck structure, what the present invention proposed can solve well without connector combined bridge deck scheme, and its fatigue of steel structures ruptures, pave-load layer very easily damages two large technical barriers, and simplify construction.
