Abstract
The invention relates to a bridge expansion device capable of meeting the requirements on three-dimensional displacement and resultant distortion, which comprises a joint crossing plate on a bridge. A fixed end of the joint crossing plate is in sleeved connection with a rotating shaft through a U-shaped bolt. The rotating shaft is fixedly connected with a displacement box. The displacement box is fixedly connected with a bridge body embedded reinforcing bar. A telescopic end of the joint crossing plate is in comb-type connection with a fixed plate. The fixed plate is fixedly connected with the bridge body embedded reinforcing bar through a bolt. A telescopic device can freely extend and retract in the longitudinal direction. In the transverse direction, the U-shaped bolt is connected with the rotating shaft in a sleeved point contact mode, so that the transverse displacement and the transverse rotation are not restrained. In the vertical direction, the vertical displacement and rotation are met also by the connection of the U-shaped bolt with the rotating shaft. When the bridge is acted by external forces, the combination of forces in all directions generates the resultant effect with undetermined direction on the bridge and the resultant distortion with undetermined direction occurs to the upper structure of the bridge. By the sleeved point contact between the U-shaped bolt and the rotating shaft, the bridge expansion device has the characteristics of meeting the multidirectional displacement of the bridge under the action of the external forces such as a load, the wind, an earthquake and the like.
Description
Technical field
The invention belongs to the means of transportation technical field, be specifically related to a kind of satisfied three-dimensional displacement and the bridge extension joint of the distortion of making a concerted effort.
Background technology
Existing stretching device is divided into modular and modulus formula two big classes, and modular is main with comb plate, and the modulus formula is main with shaped steel.Prior art all can not satisfy the function of bridge multi-directional deflection under external force effects such as load, wind-force, earthquake.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the object of the present invention is to provide a kind of satisfied three-dimensional displacement and the bridge extension joint of the distortion of making a concerted effort, have the advantages that to satisfy bridge multi-directional deflection under external force effects such as load, wind-force, earthquake.
To achieve these goals; The technical scheme that the present invention adopts is: the bridge extension joint of a kind of satisfied three-dimensional displacement and the distortion of making a concerted effort, include the transverse joint plate on the bridge, and the transverse joint plate fixed end is connected with the rotating shaft socket through U-bolt; Rotating shaft is fixedly connected with the displacement case; The displacement case is fixedly connected with beam body embedded bar, and the flexible end of transverse joint plate is connected with fixed head comb type, through above-mentioned connected mode composition activity system; Fixed head is fixedly connected with beam body embedded bar through bolt, forms fixed system.
The flexible end of said transverse joint plate is provided with movable comb plate.
The connected mode of described transverse joint plate and fixed head is interconnection.

Operating principle of the present invention is:
The operating principle of this stretching device is: when bridge the time; Bridge superstructure can be subjected to displacement and rotate, and this stretching device satisfies displacement and the rotation that is taken place, and stretching device intersects for the comb type on the longitudinal direction; Can freely stretch; Use the cover contact contact of U-bolt and rotating shaft to be connected on the transverse direction, make lateral displacement and lateral rotation unfettered, use U-bolt on the perpendicular direction equally and being connected of rotating shaft satisfy vertical displacement and rotation.
When bridge under external force effects such as load, wind-force, earthquake; The combination of all directions power produces not specified force action to bridge; The not specified distortion of making a concerted effort takes place in bridge superstructure, and the cover contact through U-bolt and rotating shaft contacts, and satisfies this kind demand of distortion with joint efforts.
Stretching device can produce vibration and noise under vehicle-mounted effect, through using the elasticity elastic damping material, will vibrate and noise weakens and absorbs, and reaches the function of antivibration and anti-noise.
