Background technology
Follow the rapid development of China's economy, the span of highway bridge is also increasing, and steel case beam has become the main flow of Longspan Bridge.Because the variation of span and tank material derives some drawbacks at joint of bridge position, for example: bridge beam body if bridge extension joint can not adapt to these distortion, just causes damage because difference variation produces vertical bridge to, direction across bridge and vertical deformation easily.
Existing bridge extension joint comprises supported box and the displacement control cabinet that is arranged under middle girder, the side bar, is provided with bearing cross beam and elastic support in the supported box, and the displacement control cabinet is provided with long-chain plate and the short chain plate that is connected through rotating shaft.This modulus formula stretching device technology maturation, on bridge the application time long, it is wide to use area, has obtained good experience.But common modulus formula stretching device can not adapt to the beam-ends vertical deformation, causes the casing unbalance stress under the situation of vertical deformation existing, and damages easily, causes the damage of whole stretching device, the harm traffic safety.
The utility model content
The technical problem that the utility model will solve just provides a kind ofly can effectively avoid various factors that bridge extension joint is damaged, and can guarantee effective cooperation of each parts of stretching device at any time, makes the steadily current multi-directional deflection modulus formula bridge extension joint of vehicle.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise the supported box and the displacement control cabinet that are arranged under middle girder, the side bar; Be provided with bearing cross beam and elastic support in the supported box, the displacement control cabinet is provided with long-chain plate and the short chain plate that is connected through rotating shaft, is provided with rotating stand in the described supported box; Rotating stand one end is sphere or cylindricality, and the other end is Baltimore groove or the plane that is complementary with bearing cross beam.
Its additional technical feature is: the Baltimore groove or the planar ends of said rotating stand are bonded with elastic body;
The sphere or the post ends of described rotating stand scribble lubricating grease;
Described rotating stand is arranged on bearing cross beam upside, downside or both sides up and down;
Rotating shaft place that is connected of said long-chain plate and short chain plate is provided with cushion;
Described middle girder is one or more.
A kind of multi-directional deflection modulus formula bridge extension joint that the utility model provided compared with prior art, is provided with rotating stand in the supported box, rotating stand one end is sphere or cylindricality, and the other end is Baltimore groove or the plane that is complementary with bearing cross beam.The sphere of rotating stand or post ends can adapt to vertical deflection, and Baltimore groove that cooperates with bearing cross beam or the planar ends of satisfying the demand can be controlled the displacement and the rotation of bearing cross beam.Like this; When bridge beam body end or abutment owing to receive external force or difference variation to cause beam-ends to rise or when sinking, rotating stand takes place to rotate up and down, drives the stretching device rotation; Avoid the destruction and the beam-ends concrete of stretching device to come off, guarantee the steady safety traffic of driving.When taking place under external force effects such as wind-force than Longspan Bridge laterally to move, can rotate about rotating stand, regulate supporting system, thereby guarantee that the stretching device vehicle that is not damaged does not steadily pass through.The combination of rotating stand and displacement control cabinet can be satisfied various distortion such as bridge inclination, distortion in addition.And the Baltimore groove of rotating stand or planar ends are bonded with elastic body, can alleviate vehicle through the time to the vibrations of bridge extension joint.The sphere of rotating stand or post ends and the high molecular abrasion-proof plate surface that is embedded in the supported box box bottom groove scribble lubricating grease, make rotation more flexible.As required, rotating stand can be arranged on bearing cross beam upside, downside or both sides up and down.Rotating shaft place that is connected of long-chain plate and short chain plate is provided with cushion, more adapts to vertical deflection.Middle girder is one or more, can adapt to the different strokes of bridge.
