It connects.
The utility model includes parallel multiple tracks work shape crossbeam 1, is fixed with longitudinal reinforcement 2 between adjacent work shape crossbeam 1, is indulged
Transverse steel 3 is fixed on reinforcing bar 2；Work shape crossbeam 1, longitudinal reinforcement 2 and transverse steel 3 form steel skeleton, in steel skeleton
Casting concrete forms concrete slab 5.Work shape crossbeam 1 at least two is located at the longitudinal two sides of concrete slab 5
Boundary.When Lifting Capacity is strong, it can be arranged among prefabricated board together or multiple tracks middle cross beam is reinforced, such prefabricated board can
It is bigger with what is done.When steel reinforced concrete combination prefabricated bridge be applied to curved bridge or broaden bridge when, work shape crossbeam 1 change length and angle
It can be adapted to, longitudinal reinforcement 2 and transverse steel 3 can be for straight muscle or with cambered curved muscle.
The section of work shape crossbeam 1 is the vertical I-section of web, is provided with aperture up and down on work shape cantilever diaphragm 13, indulges
It is fixed between twice work shape crossbeam 1 to reinforcing bar 2 by aperture.Longitudinal reinforcement 2 is double steel bar or steel hoop, transverse steel 3
For the reinforcing bar of the double-deck straight muscle, the straight muscle of bilayer zone crotch, steel hoop or other forms lateral arrangement, transverse steel 4 is wet seam
Position, the lateral connection reinforcing bar of the longitudinal reinforcement 2 for connecting contiguous prefabricated plate.Reinforcing bar can be whole, can also be more connections,
Connection and continued access between reinforcing bar are not limited to bind, and welding is connected with mechanical splice.
Work shape crossbeam 1 is variable cross-section I-beam or cross-section I-beam.When work shape crossbeam 1 is variable cross-section I-beam, work shape
Crossbeam top plate 11 is plate, and work shape crossbeam bottom plate 12 is the folded plate of multistage plate composition.Work shape crossbeam 1 is cross-section I-beam
When, work shape crossbeam top plate 11 and work shape crossbeam bottom plate 12 are plate, parallel and equidistant.Cross-section I-beam is suitable for floorings
The case where uniform thickness, variable cross-section I-beam are suitable for the case where floorings laterally thicken.
It is provided with aperture up and down on work shape crossbeam PBL stiffener 14 and is provided with lateral connection reinforcing bar 4, forms PBL key.It is horizontal
