Background technology
In the prior art, (partly) retractor device of the monoblock type bridge due to eliminating Abutment, by the flexible of bridge two ends
Seam moves to attachment strap end, and the temperature deformation of girder is transferred to attachment strap and road joining place by attachment strap, so as to become bridge expanssion joint
For road seam, seam construction is simplified, the performance of bridge is improved.But the breathing amount of the seam between attachment strap and road
It is greater than general road expansion joint (E.J.), if processing is bad, this seam or road expansion joint (E.J.) adjacent therewith will appear from disease, this is
The most common disease of (partly) monoblock type bridge.It can be said that what is do not solved so far in overall bridge or semi-monolithic bridge is most important
Problem, exactly find economical rationality, the loop control of good endurance seam (cycle-control joint), i.e., after platform attachment strap with
Seam between road surface.
For not long seamless bridge, most commonly prefabricated pointing (being also usually corruptly called expansion joint (E.J.)).For length
Bridge, then can use the fishback retractor device with kerbstone and rhone.However, seamless bridge isometric in, at present
Also without suitable loop control seam (cycle-control joint).What press strip joint seal, strip joint seal and other elasticity were made
Loop control seam (cycle-control joint) has application, but also preferable not to the utmost.
Therefore, urgent need is a kind of can overcome the telescopic bridge hazard to bridge's pier structure of prior art defect.
