Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present invention and operating principle are described in further detail.
See Fig. 1,2,3,4,5, the bridge extension joint of a kind of meeting requirements on three-dimensional displacement and distortion of making a concerted effort, include the transverse joint plate 1 on bridge 7, transverse joint plate 1 fixed end is socketed with rotating shaft 4 by U-bolt 2 and is connected, the connection of U-bolt 2 and rotating shaft 4 is for overlap contacts, reduce the activity frictional force of portable plate, rotating shaft 4 is fixedly connected with displacement case 3, displacement case 3 is fixedly connected with beam body embedded bar 8, the telescopic end of transverse joint plate 1 is connected with fixed head 5, and fixed head 5 is fixedly connected with beam body embedded bar 9 by bolt 6.
The telescopic end of described transverse joint plate 1 is provided with movable comb tooth plate 10.
Described transverse joint plate 1 is interconnection with the connected mode of fixed head 5, meets Telescopic.
Described fixed head 5 end that is connected with transverse joint plate 1 is provided with fixed fingers plate 11.
Be provided with elastic damping material bottom described movable comb tooth plate 10 and fixed fingers plate 11, meet vibration and displacement demand.
Operating principle of the present invention is:
The operating principle of this stretching device is: bridge superstructure can be subjected to displacement and rotate, this stretching device meets occurred displacement and rotation, on longitudinal direction, stretching device is that combed is intersected, can free-extension, transverse direction use U-bolt be connected with the cover contacts of rotating shaft, make lateral displacement and lateral rotation unfettered, use the connection of U-bolt and rotating shaft to meet vertical displacement and rotation equally on perpendicular direction.
When bridge is under the External Force Actings such as load, wind-force, earthquake, the combination of all directions power produces not specified force action to bridge, there is not specified distortion of making a concerted effort in bridge superstructure, by the cover contacts of U-bolt and rotating shaft, meets this kind and to make a concerted effort the demand of distortion.
Stretching device can produce vibration and noise under vehicle loading, by using elastic damping material, will vibrate and slowed noise and absorption, and reaching the function of antivibration and anti-noise.
