The gradient of both sides web is 1：3.5.
Below by way of accompanying drawing and embodiment, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of U ribs in the utility model.
Embodiment
As shown in figure 1, the utility model orthotropic plate-concrete combined bridge deck, including steel plate 1, it is arranged on steel
Bar-mat reinforcement 2 on plate 1, the shear connector being arranged on steel plate 1, the steel plate 1, bar-mat reinforcement 2, shear connector are by pouring
Concrete layer 3 in the upper surface of steel plate 1 embed it is into a single integrated structure, the concrete layer 3 be provided with wearing course 4, the bottom of steel plate 1
Portion is interval with U ribs 5 and diaphragm plate 6, and preferably described concrete layer 3 is ECC concrete layers, RPC concrete layers, STC coagulations
One kind in soil layer.It is preferred that the shear connector is peg.The RPC concrete layers of the concrete layer 3 preferably wherein, it is described
RPC concrete layers are made up of level with good sand, cement, finely-powdered minerals, silicon ash, steel fibre etc., and water-cement ratio is very low, and it is prepared
Principle is by improving the fineness of component and activity, optimizing grain composition and fill micro steel fiber, make the defect of material internal
Reduce, compactness increase, so as to have the advantages that high intensity, high tenacity and high-durability.It is used as steel plate and concrete layer structure
Between connector, while one kind in the above-mentioned high performance concrete layer used in view of concrete layer, its thickness is smaller, adopts
It is attached with short peg.
As shown in Fig. 2 H is the height of U ribs, d is the A/F of U ribs, and the gradient is the inclination at α angles in Fig. 2
Degree.The A/F of U ribs 5 is that the height of 380-520mm, U rib 5 is that 340-420mm, the gradient of the both sides web of the U ribs 5 are
1：3.2-1:3.8.Wherein preferably the A/F of U ribs 5 is 450mm.The height of U ribs 5 is 375mm.The both sides of U ribs 5
The gradient of web 51 is 1：3.5.Proved according to experiment, U ribs have preferable antifatigue effect under above-mentioned size condition,
The A/F of U ribs 5 is 450mm.The height of U ribs 5 is 375mm.The gradient of the both sides web 51 of U ribs 5 is 1：3.5 size
Under the conditions of antifatigue effect be optimal.
Proved by testing, compared with the different in nature steel bridge deck of conventional orthogonal, pass through above-mentioned U ribs, steel plate in the utility model
It is combination stressed with high performance concrete layer, add cross sectional moment of inertia, improve the local stiffness at the top of combined bridge deck, so that
The stress amplitude of fatigue concern details is reduced, the anti-fatigue performance of combined bridge deck is improved.Wherein use the U in the utility model
