Description
Technical field
Composite bridge prefabricated bridge and its dry type connection method the present invention relates to a kind of connection of dry type
Background technology
Composite bridge is a kind of new knot grown up on steel structure bridge and concrete structure bridge foundation
Structure bridge.It is (peg, channel-section steel, curved by setting between the girder steel of bottom and the concrete slab on top shear connector
Muscle etc.), both resistances starting at interface and Relative slidings make the floorings cooperation of girder steel and concrete, turn into
One beam of overall work.In composite bridge, the connection method of the floorings of precast block：By adjacent bridge panel end
The reinforcing bar for exposing carries out colligation and cast-in-place wet seam, and wet seam solidification completes the connection of adjacent floorings.This connected mode
There are substantial amounts of bar connecting work and joint filler to pour work at the construction field (site), long construction period, the environmental pollution at scene is big.
The content of the invention
The first object of the present invention is to provide a kind of composite bridge prefabricated bridge of dry type connection, and this kind prefabricated
Floorings can improve the precast assembly degree of component in science of bridge building, reduce site operation amount, reduce the environmental pollution at scene,
Accelerate speed of application.
The present invention realize technical scheme that its first goal of the invention used for：A kind of composite bridge of dry type connection
With prefabricated bridge, its composition is：The connecting end surface of prefabricated bridge is fixed with stave sheet, and prefabricated bridge is stretched out in the bottom of stave sheet
The bottom surface of panel ()；The bottom surface of the connection end of prefabricated bridge is fixed with horizontal steel plate.
The second object of the present invention is to provide a kind of prefabricated bridge floor of composite bridge connected using above-mentioned dry type
Plate, is combined the dry type connection method of structural bridge prefabricated bridge.The method can simply and easily realize combination knot
The dry type connection of structure bridge prefabricated bridge, reduces site operation amount, reduces the environmental pollution at scene, accelerates speed of application.
The present invention realize a kind of technical scheme that its second goal of the invention used for：It is a kind of to be connected using above-mentioned dry type
Composite bridge prefabricated bridge, be combined the dry type connection method of structural bridge prefabricated bridge, its practice
It is：
Prefabricated bridge is installed on girder steel, and the connecting end surface of contiguous prefabricated floorings is alignd, then will be adjacent pre-
The buckle clamping of the upper end of the stave sheet of floorings processed, the bottom that stave sheet stretches out prefabricated bridge bottom surface is mutually welded
Connect, that is, complete the dry type connection of contiguous prefabricated floorings.
The present invention realize another technical scheme that its second goal of the invention used for：It is a kind of to be connected using above-mentioned dry type
The composite bridge prefabricated bridge for connecing, is combined the dry type connection method of structural bridge prefabricated bridge, its work
Method is：
Prefabricated bridge is installed on girder steel, and the connecting end surface of contiguous prefabricated floorings is alignd；Again will be adjacent pre-
The upper end of the stave sheet of floorings processed is welded to each other, then gets out connection in the bottom that stave sheet stretches out prefabricated bridge bottom surface
Hole, then realizes the bolt connection of adjacent stave sheet bottom with bolt by described connecting hole, that is, complete contiguous prefabricated bridge floor
The dry type connection of plate.
The present invention realize the third technical scheme that its second goal of the invention used for：It is a kind of to be connected using above-mentioned dry type
The composite bridge prefabricated bridge for connecing, is combined the dry type connection method of structural bridge prefabricated bridge, its work
Method is：
Prefabricated bridge is installed on girder steel, and the connecting end surface of contiguous prefabricated floorings is alignd；Again will be adjacent pre-
The upper end of the stave sheet of floorings processed is welded to each other, then gets out connection in the bottom that stave sheet stretches out prefabricated bridge bottom surface
Hole, then realizes the riveting of adjacent stave sheet bottom with rivet by described connecting hole, that is, complete contiguous prefabricated floorings
Dry type is connected.
Operation principle of the invention is：
Under load action, composite bridge floorings will bear axle power, shearing, moment of flexure, and its connecting portion is bridge floor
Effective part of plate, the key of dry type connecting structure need to have bears axle power, shearing moment of flexure with floorings identical
Ability, stave sheet of the invention, horizontal steel plate and floorings are fixedly connected as entirety, and this work can be completed in pre-fabricated factory,
Avoid poured in place concrete.The axle power of floorings can be by the smooth transmission of smooth joint face of stave sheet；It is negative curved when bearing
During square, the weld seam of upper end, clamping structure bear pulling force, and the bottom joint face of stave sheet bears pressure, and the two couple for constituting can
Hogging moment is offset, when this connecting structure bears sagging moment, the bolt of downside or is welded to connect and is born pulling force, upside joint face holds
It is stressed, the two couple for constituting can offset sagging moment；When bearing shearing, the spiral shell of the weld seam, clamping structure and downside of upper end
Bolt, it is welded to connect and can bear shearing, therefore, dry type connecting portion of the invention has and good bears axle power, shearing, moment of flexure
Ability, so as to the floorings of precast block are connected as into entirety, with one-piece casting floorings identical structural behaviour.
Compared with prior art, the beneficial effects of the invention are as follows：
First, using bolt, welding or the connection of the dry type such as buckle between contiguous prefabricated floorings, it is to avoid cast in situs is wet to be connect
The wet type of seam connects required installation form, assembling reinforcement, pours the operations such as joint concrete, maintenance joint concrete, significantly
Accelerate construction speed.
2nd, element precast assembly rate is high.The group weldering of stave sheet, horizontal steel plate and its connector, floorings to pour work equal
Can be completed in factory, the crudy of component can be guaranteed, scene need to only carry out dry type assembly, connection and form floorings
Between interconnection, meet the developing direction of China's building industrialization, assemblyization.
3rd, between each prefabricated bridge between using the connection of the dry type such as bolt, weld seam or trip, it is to avoid cast in situs is wet
The concrete that seam is likely to occur trickles, maintenance current drop down caused environmental pollution.
Further, the concrete structure of the connecting end surface fixation stave sheet of prefabricated bridge of the invention is：Stave sheet
Upper weld has transverse connection, and transverse connection is embedded in prefabricated bridge in advance and stave sheet is exposed into prefabricated bridge
The connecting end surface of panel；
The concrete structure that horizontal steel plate is fixed in the bottom surface of the connection end of prefabricated bridge of the invention is：Welded on horizontal steel plate
There is vertical connector, and vertical connector is embedded in prefabricated bridge and by horizontal plate exposure in the company of prefabricated bridge in advance
Connect end bottom surface.
So, can simply and easily by stave sheet and horizontal Interal fixation on prefabricated bridge, and its fixation, can
Lean on.
Further, stave sheet of the invention stretches out between the bottom of prefabricated bridge bottom surface and horizontal steel plate and is welded with ribs
Plate；Described stave sheet and the contact site of horizontal steel plate are welded to connect.
So, stave sheet and horizontal steel plate can form more firm entirety, further increase the bridge floor of present invention connection
The structural behaviour of plate.
