Description

The bridge extension joint of a kind of meeting requirements on three-dimensional displacement and distortion of making a concerted effort
Technical field
The invention belongs to means of transportation technical field, be specifically related to the bridge extension joint of the displacement of a kind of meeting requirements on three-dimensional and distortion of making a concerted effort.
Background technology
Existing stretching device is divided into modular and the large class of modulus type two, and modular is based on comb plate, and modulus type is based on shaped steel.Prior art all can not meet the function of bridge multi-directional deflection under the External Force Actings such as load, wind-force, earthquake.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the bridge extension joint of the displacement of a kind of meeting requirements on three-dimensional and distortion of making a concerted effort, having the advantages that to meet bridge multi-directional deflection under the External Force Actings such as load, wind-force, earthquake.
To achieve these goals, the technical solution used in the present invention is: 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 on bridge, transverse joint plate fixed end to be socketed with rotating shaft by U-bolt and to be connected, rotating shaft is fixedly connected with displacement case, displacement case is fixedly connected with beam body embedded bar, and the telescopic end of transverse joint plate is connected with fixed head combed, by above-mentioned connected mode composition activity system; Fixed head is fixedly connected with beam body embedded bar by bolt, composition fixed system.
The telescopic end of described transverse joint plate is provided with movable comb tooth plate.

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.
