Technical field
The utility model relates to a kind of bridge deck that can be applicable to highway large span compound beam suspension bridge, belongs to the bridge construction technical field.
Background technology
Tradition suspension bridge steel concrete combined bridge deck system as shown in Figure 1, is made up of steel longeron 1, gooseneck 2, tuyere 3, peg connector 4, precast concrete plank 11 and cast-in-situ concrete seam 6.Sections steel main beam structure is transported to the job site hoisting and locating after factory's welding.The plate end of precast concrete plank 11 must be made into the profile of tooth notch, there are problems such as field operation amount and difficulty of construction are bigger, simultaneously precast concrete plank 11 and cast-in-situ concrete seam 6 be because casting space is narrow and small, and the concrete pouring difficult quality guarantee influences the stress performance of bond between fresh and hardened concretes portion.On the other hand, tradition suspension bridge steel concrete combined bridge deck ties up to steel longeron 1 and gooseneck 2 tops all are provided with peg connector 4, the forced deformation that effects such as 1 couple of concrete slab Yin Wendu of steel longeron, shrinkage and creep cause has tangible effect of contraction, especially because of being set, peg connector 4 causes significant stress concentration phenomenon at suspension centre place concrete slab, be very easy to cause concrete slab generation cracking phenomena, thereby reduce the bearing capacity and the rigidity of structure, influence durability of structures.These problems have caused certain difficulty all for applying of this class formation.
The utility model content
The purpose of this utility model provides a kind of with respect to traditional suspension bridge steel concrete combined bridge deck system, simplify the manufacture craft of precast concrete plank, field operation amount and difficulty of construction be less, reduce simultaneously steel girder and concrete slab the complicated applied force zone be connected degree with and to the release action of effects such as concrete slab temperature, shrinkage and creep, the concrete pouring quality is easy to guarantee, structural bearing capacity, rigidity and cracking resistance is higher, economic performance is more excellent suspension bridge steel concrete combined bridge deck system.
The technical solution of the utility model is as follows: the utility model has the following advantages with respect to prior art:
(1) concrete slab pressurized, bottom girder steel tension is given full play to the material property of concrete and steel excellence by compound action.Than traditional suspension bridge steel concrete combined bridge deck system, the utility model has discharged the forced deformation that effects such as concrete slab Yin Wendu, shrinkage and creep cause by the degree that is connected that reduces steel girder and concrete slab, effectively alleviate the stress concentration phenomenon of suspension centre place concrete slab, reduced the concrete cracking risk.Concrete slab and gooseneck are combined to form the more clear and definite freely-supported compound beam stress system of mechanical characteristic, have bearing capacity height, easy construction, from advantage such as heavy and light, anti-seismic performance be good, and having improved structure durability, is the important improvement that is to traditional suspension bridge steel concrete combined bridge deck.
(2) the suspension bridge steel concrete combined bridge deck system that adopts a kind of part of the present utility model not make up by factory's precast segment, is transported to the bridge location scene and sets up assembly unit, the field operation amount is little, and construction quality is easy to guarantee, and is little to the bridge location environmental disturbances, environmental protection meets the sustainable development requirement.Wherein, when factory's precast segment, precast concrete plank can be used as the construction formwork of cast-in-situ concrete seam, can avoid a die process, reduces concrete wet trade amount and difficulty of construction, shortens construction period, accelerating construction progress.
(3) form the concrete folding structure by the shearing resistance effect of dihedral shear reinforcement, the drawknot effect of plate end bar and the interface cementation of precast plate and cast-in-situ concrete layer, its overall performance is good, can guarantee that bond damage does not take place before reaching ultimate limit state structure.
(4) by traditional precast plate structure is improved, make precast plate plate end tooth shape notch into stairstepping, simplified the precast concrete plank manufacture craft, avoided problems such as traditional precast concrete plank cracking and durability, easy construction, stress performance are good.
(5) the local suspension bridge steel concrete combined bridge deck system that does not make up than traditional suspension bridge steel concrete combined bridge deck tie up to stress performance, when workability significantly improves, steel using amount does not almost increase, economic performance is more excellent.

The specific embodiment
Below in conjunction with accompanying drawing, structure of the present utility model, work progress are further described.
It is a kind of with respect to traditional suspension bridge steel concrete combined bridge deck system that the utility model provides, and field operation amount and difficulty of construction are less, the concrete pouring quality is easy to guarantee, suspension bridge steel concrete combined bridge deck system is not made up in structural bearing capacity, rigidity and cracking resistance is higher, economic performance is more excellent part.As Fig. 2～shown in Figure 5, this structure is made up of steel longeron 1, gooseneck 2, tuyere 3, peg connector 4, precast concrete plank 5 and cast-in-situ concrete seam 6, is suspended to the main push-towing rope bottom by hoist cable 10.Steel longeron 1, gooseneck 2 and tuyere 3 are by being welded to connect into sections steel girder; Also predeterminable steel mesh reinforcement and plate end reserved steel bar 7, dihedral shear reinforcement 8 in the described precast concrete plank 5, and connect into integral body by cast-in-situ concrete seam 6 and peg connector 4 and sections steel girder.Precast concrete plank 5 and cast-in-situ concrete seam 6 only are connected to form integral body with gooseneck 2 by peg connector 4, and the peg connector is not set on the steel longeron 1; Simultaneously in certain zone, gooseneck 2 ends, suspension centre place, peg connector 4 is not set; Precast concrete plank 5 and cast-in-situ concrete seam 6 also can be by being connected to form integral body to reinforcing bar 9 in plate end reserved steel bar 7, dihedral shear reinforcement 8 and the cast-in-situ concrete seam in length and breadth.
