Background technology
Expansion Units for Highway Bridges is one of the important component of highway bridge construction, and function is to make bridge structure object
Under the action of the factors such as temperature change and concrete or steel contraction, creeping displacement and dynamic load, it can keep freely more
The flexible of direction is tieed up, to adapt to the various modifications of highway bridge structure, being ensured in highway bridge normal operation for one must can not
Few structural devices.
With increasing sharply for the volume of traffic and heavy goods vehicles, especially overloading is serious in recent years, keeps highway bridge flexible
The destruction situation of device is increasingly severe, is exposed in air in the wild for a long time in the telescopic device use of highway bridge, uses ring
Border is more severe, is most to be subject to destroy in bridge structure and be relatively difficult to the position repaired.Existing telescopic device uses completely
Simple steel manufacture, connects although with different mechanical structures and designs, but be not fully solved telescopic device there are the problem of.
Telescopic device rigidity and flexibility are difficult to reach balance and take into account, and increase the flexibility of telescopic device, then it cannot be guaranteed that the driving at expansion joint
The end of safety and highway safety bridge member；The rigidity for increasing telescopic device, then can not usually adapt to the more of expansion joint position
To displacement, lead to the fracture damage of the components such as telescopic device installation anchoring piece.
Expansion Units for Highway Bridges is generally various types comb teeth retractor device in the prior art, by docking fishback
Block interts to realize its retractility mutually, but each adjacent fingers vertical side is plane, and it is cantilever to cause each broach
The free end state of beam, the deformation of broach independent stressed limit constraint support without upper and lower vertical direction from each other, can not be mutual
Alternation position load force according to legend is easy fatigue fracture, leads to serious traffic safety accident；In addition installation and in use, broach very
It is easy to form hanging stress, under the vehicle-mounted pressure effect of long-term dynamics, broach may be deformed and be upwarped, therefore be seriously affected
Traffic safety.
