Part is fixedly connected on above described orthotropic plate, and the longitudinally reinforced reinforcing bar let-down in concrete slab is arranged in band semienclosed slot
In the slotted eye of lateral opening plate shear connector；Horizontal stiffener let-down in concrete slab is arranged in the longitudinal direction of band semienclosed slot
In the slotted eye of perforated panel shear connector.
Further, described longitudinal perforated panel shear connector is longitudinally arranged, described lateral opening plate shear connector lateral arrangement,
In both vertical junctions, longitudinal perforated panel shear connector disconnects, and lateral opening plate shear connector is the most through.
Longitudinal perforated panel shear connector of described band semienclosed slot is slotted hole steel plate strip, and slotted eye is circular, is fixedly connected on
Above the orthotropic plate of ribbed stiffener.
The lateral opening plate shear connector of described band semienclosed slot is slotted hole steel plate strip, and slotted eye is boot-shaped, is fixedly connected on
Above the orthotropic plate of ribbed stiffener.
Described longitudinally reinforced reinforcing bar is along longitudinally elongated layout, the most elongated layout of horizontal stiffener.
The spacing of described longitudinally reinforced reinforcing bar is equal to the slot pitch of the lateral opening plate shear connector of band semienclosed slot.
The spacing of described horizontal stiffener is equal to the slot pitch of longitudinal perforated panel shear connector of band semienclosed slot.
Described ribbed stiffener uses U rib, I rib, the rib of falling T or flat-bulb steel.
Described concrete slab is normal strength concrete slab or high performance concrete plate.
Described being fixedly connected as is welded.
Owing to using technique scheme, this utility model has the advantages that
1) the orthotropic combined bridge deck of band ribbed stiffener is compared with conventional combination floorings, and deadweight alleviates significantly；
2) compared with Orthotropic Steel Bridge Deck, substantially improve again fatigue, the problem such as mat formation, and reduce steel using amount, reduce
Cost；
3) compared with welding nail connector, perforated plate connector has that shear stiffness is big, anti-fatigue performance good, and steel plate passes through perforate and concrete
Form the biggest dowel action, more efficiently ensure steel and the cooperation of concrete；
4) semi-enclosed slotted eye makes to arrange that the stiffener in concrete becomes very convenient, it is to avoid reinforcing bar is from plurality of rows of hole
In the complicated processes interted, save manpower and materials, improve efficiency of construction.
5) bar spacing defers to the spacing layout of slotted eye on perforated panel, owing to the slotted eye of perforated panel also determines the height of vertically and horizontally reinforcing bar
Difference, so the perforated plate connector of trough of belt, is especially advantageous for the control of size positions during steel bar arrangement.
