This stiffening rib is slab, slab with holes, T shape slab.
This stiffening rib distributes and is spaced apart 50～90t (t is that end steel plate is thick), and it highly is no more than 2/3 of bridge deck height.
Described bridge deck are installed on the bridge main beam by second shear connector.
A kind of preparation method of novel combined bridge deck, it is provided with the first shearing connecting key on base plate; Base plate is installed on the bridge main beam top flange plate, the second shearing connecting key that is connected usefulness with bridge deck has been set on the girder top flange plate; Lay the required power of joining muscle of bridge deck and upside main force muscle, fluid concrete.
Further, when first shear connector is set on the base plate, stiffening rib can also be set.
Owing to adopted such scheme, the present invention to have following characteristics:
Reduce the bridge deck thickness of slab effectively, reduced the dead loading of design of bridge;
Save setting up and removing of concrete casting injection molded plate, shorten the construction period;
Have favorable durability, fatigue resistance is easy to safeguard.

The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
As shown in Figure 1 and Figure 2, bridge main beam 100 (box-girder or i-shaped roof beam) is connected by second shear connector 150 on girder 100 top flange plates with combined bridge deck, and the end steel plate 120 of combined bridge deck is connected with steel concrete by first shear connector 140 and stiffening rib 130.The design of the second shearing connecting key 150 can be with reference to general compound beam shearing connecting key design; First shear connector 140 and stiffening rib 130 mainly are to guarantee being connected of end steel plate 120 and steel concrete in design; Stiffening rib 130 will guarantee that also end steel plate 120 has certain rigidity before hardening of concrete, and can bear weight concrete and construction loading.End steel plate 120 thickness of bridge deck are generally got 8～16mm.According to girder interval, bridge length and construction hoisting ability, can transversely be respectively 120-1,120-2,120-3 as bridge among Fig. 2 end steel plate 120 in axially transversely piecemeal making of bridge, Fig. 1 is the stereogram of bridge direction of principal axis last one minute of module unit.End steel plate 120 can not have bridge deck under the special shape requirement according to the shape arch camber or the bending of bridge deck, and for ease of making, end steel plate also can be made smooth. The shape of end steel plate stiffening rib 130 can be slab, slab with holes, T shape slab etc.Stiffening rib 130 configuration spaces are according to the desirable 50～90t of end steel plate 120 thickness (t is that end steel plate is thick), but must guarantee that answer dynamics and the rigidity of end steel plate 120 when fluid concrete meets the demands.Stiffening rib 130 considers that highly factor such as configuration upside reinforcing bar had better not surpass 2/3 of bridge deck height. The form of the first shearing connecting key 140 can adopt bar steel, bar shaped steel, slab etc.The general identical shearing connecting key form of combined bridge is wanted to guarantee the compound action of end steel plate and steel concrete, but simultaneously concrete poured into a mould smoothly, at interval can not be too little, and the desirable 100～250mm of configuration space. End steel plate stiffening rib connector 160 and end steel plate connecting elements 170 during the piecemeal fabrication and installation can or be welded to connect with high-strength bolt.
The production method of combined bridge deck of the present invention is: at first make end steel plate 120-1,120-2,120-3 at factory's piecemeal, the corresponding stiffening rib 130 and the first shearing connecting key 140 of welding on end steel plate, on-the-spot piecemeal is installed on the girder top flange plate and (has set the second shearing connecting key 150 that connects usefulness this moment on the girder top flange plate), form whole by stiffening rib syndeton 160 and steel plate syndeton of the axial end of bridge 170, steel plate integral body just has certain rigidity and supporting capacity at the end like this, can be used as operation platform and concrete casting injection molded plate.Bridge deck side reinforcing bar 180 and other lacings (not marking among the figure) on the built, fluid concrete thereon again, after the hardening of concrete, end steel plate just can form combined bridge deck by first shear connector 140 and stiffening rib 130 with the steel concrete combination.Combined bridge deck is fixed in bridge main beam by second shear connector 150.
Combined bridge deck of the present invention, utilize end steel plate and concrete compound action, strengthened the supporting capacity of bridge deck to a great extent, thereby reduced the thickness of slab of bridge deck, reduce the dead loading of design of bridge, reduced the integral bridge cost that comprises the bottom worker effectively.
In addition, stiffening rib rationally is set on end steel plate, makes end steel plate before hardening of concrete, just have certain supporting capacity, make end steel plate can become the template of concrete pouring naturally in the construction stage, thereby save setting up and removing of cast template, shorten the construction period.And when bridge deck are studied for a second time courses one has flunked,, can just can easily replace steel concrete, thereby help maintenance without template and safeguard procedures because of end steel plate can bear certain construction loading.
The end steel plate of combined bridge deck of the present invention can be made in factory process, can better guarantee crudy, and the end steel plate after putting more energy into has good rigidity and supporting capacity, also can guarantee the casting quality of on-site concrete.Bridge deck integral body is easy to safeguard and study for a second time courses one has flunked, thereby can saves overall life cycle cost.
Therefore bridge deck form of the present invention has tangible economic effect, can be widely used in the bridge of steel and combining structure.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
