Description
Technical field
The present invention relates to a kind of Railway Prestressed Concrete box-girder composite bridge floor affiliated facility.
Background technology
Railway Prestressed Concrete box-girder progressively replaces T beams in railway construction, becomes in railroad bridge construction and applies
Most commonly used beam type.The box-girder is one kind of science of bridge building central sill, and inside is hollow shape, and there are the edge of a wing, class in top both sides
Like chest.Bridge floor affiliated facility is the accessory structure outside bridge main body structural shielding wall, essential, plays important auxiliary
Function, its affiliated facility mainly includes shield, cable trough, straight wall, cable trough cover boards (doubling as foot plank), railing, sound barrier etc..
Wherein, shield be prefabricated reinforced concrete structure, straight wall be cast-in-place or prefabricated reinforced concrete structure, cable trough
Cover plate is precast rc slab or RPC plates, and railing is steel construction or prefabricated reinforced concrete structure, therefore affiliated facility matter
Amount is very big, substantially increases the secondary dead load of box-girder, and box-girder must increase physical dimension or increase with reinforcing bar, increases pre-
Stress rib to bear the load, so as to increase beam body weight.Existing Railway Prestressed Concrete box-girder bridge floor affiliated facility,
Shield, railing, cable trough cover boards are prefabricated, and straight wall is cast-in-place or prefabricated.Box-girder make when on the edge of a wing exposed portion
Reinforcing bar or built-in fitting, also exposed portion reinforcing bar when shield and railing concrete component make, during installation, by prefabricated concrete structure
The reinforcing bar exposed on reinforcing bar that part exposes and box-shaped flange of beam carries out colligation, by cast-in-place model sheetinstallat it is good after, penetration concrete,
Just entirety is formed with box-girder after solidification, process of setting needs to be conserved, and curing time is different because weather is different, general need
Take more than 7 days.Existing box-girder affiliated facility adopts cast in situs armored concrete, needs to experience assembling reinforcement, shuttering, shows
The operations such as pouring concrete, health preserving, form removal, surface treatment, complex process, construction period is longer, increased construction cost,
The requirement of rapid construction can not be met.The production of reinforcing bar and concrete is both needed to consume substantial amounts of fuel, and noxious substance and big
Amount dust emission, neither energy-conservation are also not environmentally.Cast-in-place straight wall constitutes two to three grooves together with the protecting wall on box-girder
As cable trough, after cable laying is finished, prefabricated reinforced concrete or RPC cover plates is shelved (as walking in straight wall upper surface
Plate).The column that shield upper surface arranged for interval has built-in fitting, railing or sound barrier passes through installation of embedded parts on shield.Help
Handss are attached fixation with railing post, and sound barrier is attached fixation with noise barrier stand column.Existing Railway Prestressed Concrete
The beam prefabricated affiliated facility quality of box-shaped is excessive, and the requirement in work progress to construction appliance is again higher, needs during in-site installation
Equipment is hung, so as to increase plant equipment cost, also all peace can be caused to workmen and live material in transport and hoisting process
Full hidden danger.
