Description
Technical field
The utility model relates to a kind of rigid connection structures for bridge, and in particular to a kind of reusable bridge
Assembled closure section rigid connection component.
Background technique
With the deep popularization of the theories such as Green Bridges, circular economy, steel construction is widely used in bridge construction field,
Temporary structure especially in bridge construction, frequently with standardization detachable member, farthest to carry out weight to steel construction
It is multiple to utilize.
To ensure that going on smoothly for concrete-bridge closure section construction is linear to reach the design of bridge, connect frequently with rigidity
It connects and closure section beam sections at two sides is temporarily rigidly connected by means appropriate, then casting closure section concrete or lifting
Closure section removes rigid connection component, then the complete closure section steel beam of tensioning after the section concrete that joins the two sections of a bridge, etc reaches design strength, completes to close
Imperial section construction.
Conventional closure section rigid connection component is typically employed in bridge box and beam top, pre-buried anchor bar or fashioned iron in bottom plate,
In top welding steel, fashioned iron is welded on pre-embedded steel slab again when outside air temperature reaches design closure temperature and forms entirety,
Reach closure section beam sections at two sides temporarily rigidly connected purpose.The way has the following problems: 1, pre-buried fashioned iron, reinforcing bar can not
It removes and recycling, consumption of materials is big；2, it is big to remove rigid connection member difficulty, still has part steel construction exposed after dismounting
Influence appearance；3, it in roof and floor lower thickness regions because of embedded bar etc., needs locally to thicken roof and floor, cause largely mixed
The waste of the materials such as solidifying soil, reinforcing bar；4, rigid connection steel member can not utilize again after removing, and be only capable of being recycled；5, rigidity
Once connection steel member length blanking will be unable to adjustment length, the closure section of a certain specific length only can be suitably used for；6, work as the external world
The scene welding for steel structure time is longer when temperature reaches design closure temperature, it is more difficult to control best closure opportunity.
