Background technology
At present, bridge deck many employings orthotropic steel bridge deck of long-span cablestayed bridges or suspension bridge coordinates the form of epoxy asphalt pavement.Engineering practice shows, due to stiffening rib complex structure, bridge floor rigidity is lower, steel-reason such as asphalt interface adhesive property difference, and orthotropic steel bridge deck exists two large diseases under Vehicle Load, i.e. the fatigue fracture of steel work and asphalt mixture surfacing disease.Concreting on bridge floor steel work top board, and with shear connector or shear connections measure, steel work and concrete are linked to be entirety, form composite steel concrete bridge face system, effectively can reduce the stress level of steel work under vehicular load, improve bridge floor rigidity, strengthen the adhesive property of pitch and bridge floor, thus improve fatigue of steel structures cracking and asphalt mixture surfacing disease problem.
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.When bridge bears across-wind dynamic load, outside bridge floor, larger tensile stress may be there is.Outside bridge floor, lay ultra-high performance concrete and ordinary concrete respectively with inner side, both effectively can improve the cracking resistance of bridge floor under across-wind dynamic load effect, and bridge floor cost can be reduced again, and make full use of the comprehensive advantage that combined effect brings.
Summary of the invention
The object of the present invention is to provide a kind of bearing capacity is high, rigidity is large, cracking resistance the is good bridge deck laterally strong combining structure bridge floor system such as not, the advantage of comprehensive utilization steel, ordinary concrete and ultra-high performance concrete, thus obtain more preferably stress performance, workability and comprehensive economic index.
A kind of bridge deck of the present invention laterally strong composite steel concrete bridge face system such as not, it is characterized in that, this combined bridge deck system comprises the ultra-high performance concrete outside bridge floor, the ordinary concrete inside bridge floor and bridge floor steel work, outside two, lay ultra-high performance concrete in 1/8 ~ 1/4 bridge wide region along bridge deck width direction, in residue width range, lay ordinary concrete.
The end face of described bridge floor steel work is provided with shear connections measure and bridge deck concrete and bridge steel structure is linked to be entirety.
The end face shear connections treatment measures of described bridge floor steel work are with protruding pattern at the end face weld stud of bridge floor steel work or the end face of bridge floor steel work.
Reinforcing bar is laid in ordinary concrete inside ultra-high performance concrete and bridge floor outside bridge floor.
Steel fibre is laid in described ultra-high performance concrete.
The construction method of the horizontal strong composite steel concrete bridge face system such as or not bridge deck of the present invention, it is characterized in that, this construction method step is as follows:
(1) bridge floor steel work is installed;
(2) outside bridge floor, ultra-high performance concrete is built;
(3) inside bridge floor, ordinary concrete is built.
After described step (1), on the top board of bridge floor steel work, the top board of weld stud or bridge floor steel work adopts the steel plate of band protruding pattern.
Reinforcing bar is laid in ordinary concrete inside ultra-high performance concrete and bridge floor outside bridge floor.
Configuration steel fibre in described ultra-high performance concrete.
The present invention has following outstanding advantage relative to prior art: the concrete 1. bridge floor steel work top board laid and steel work form entirety, effectively improves the strength and stiffness of bridge floor, thus reduces the stiffening rib structure of steel work top board, reduces the steel using amount of bridge floor; 2. outside bridge floor, ultra-high performance concrete and ordinary concrete is laid respectively with inner side, both the cracking resistance of bridge floor under across-wind dynamic load effect (greatly across the crack-resisting design of flexible bridge structure system concrete slab often by across-wind dynamic load operating conditions) can effectively have been improved, bridge floor cost can be reduced again, make full use of the advantage that combined effect brings; 3. the interfacial bond property due to concrete and asphalt pavement is better, and the asphalt mixture surfacing that bridge deck concrete is laid not easily disease occurs; 4., when concrete uses as the bridge deck bearing Vehicle Load, deck paving layer thickness and expense thereof can significantly be reduced.
