A kind of bridge expansion joint installation
Technical field
The present invention relates to a kind of bridge expansion joint installation.
Background technology
The need for meeting bridge beam body deformation, typically between two beam-ends of bridge, between beam-ends and abutment or
Bridge expansion joint installation is fitted with the articulated position of bridge.At present, the state-of-the-art bridge expansion joint installation of technology is general all
Length travel, longitudinal corner, level angle three-dimensional deflection function are provided simultaneously with, most bridges can be met to bridge expanssion joint
The requirement of device, but some large bridges are in use by environment, temperature, heavy duty, strong wind, ocean current, tide, earthquake shadow
Ring, in addition to length travel, longitudinal corner, level angle is produced, can also produce lateral displacement, and due to existing bridge expanssion joint
Device can not also realize lateral deflection function, thus easily cause the damage of expansion gap device and beam body.In summary, need pair
Existing bridge expansion joint installation is further improved.
The content of the invention
The technical problems to be solved by the invention be for above-mentioned state of the art there is provided one kind it is simple in construction, possess
The bridge expansion joint installation of lateral displacement function.
The present invention solve the technical scheme that is used of above-mentioned technical problem for:The bridge expansion joint installation, it is characterised in that:
Including upper telescoping member and lower telescoping member, the bottom of the upper telescoping member is provided with the first limit assembly, described lower flexible
Second limit assembly is installed, the second described limit assembly and the first limit assembly cooperate, and make institute at the top of component
State telescoping member and lower telescoping member is limited in the horizontal of bridge and relatively moved.
As a kind of preferred scheme, the first described limit assembly is to be fixed on telescoping member bottom and horizontal along bridge
To the first dovetail geosynclinal block of distribution, the second described limit assembly is to be fixed on the top of lower telescoping member and along bridge lateral
Second dovetail geosynclinal block of distribution, described the first dovetail geosynclinal block and the second dovetail geosynclinal block is mutually embedded and slides setting.So, when
Bridge is by heavy duty, strong wind, ocean current, tide, earthquake effect, and when being moved horizontally along pier generation, the bridge expansion joint installation passes through
First dovetails and the second dovetails produce relative slip, the bridge expansion joint installation is had lateral displacement function.
As another preferred scheme, the first described limit assembly includes the locking screw for being fixed on telescoping member bottom
Bolt and the spacing collar being set in outside clamping screw, the second described limit assembly is to be fixed on the cunning at the top of lower telescoping member
Plate, is provided with the mounting hole being engaged with the spacing collar, the length direction of mounting hole and the transverse direction of bridge on the slide plate
Consistent, the spacing collar is movably arranged in described mounting hole, and is compressed in spacing collar by upper telescoping member bottom
In the state of, leave gap between the upper telescoping member bottom and slide plate.So, when bridge is by heavy duty, strong wind, ocean current, tide
Nighttide, earthquake effect, when being moved horizontally along pier generation, the bridge expansion joint installation passes through spacing collar and slide plate produces relative move
It is dynamic, make the bridge expansion joint installation that there is lateral displacement function.
As the further preferred of such scheme, described mounting hole is divided into two row and respectively positioned at the two of the slide plate
Side, accordingly, described clamping screw and spacing collar are also divided into two row and respectively positioned at the upper telescoping member bottom
Both sides.So, the lateral displacement of expansion gap device is more stablized.
Further preferably, described upper telescoping member includes fixed broach plate and can be relatively fixed fishback in bridge longitudinal direction
Mobile transverse joint plate.So, when because of environment temperature and external force along bridge direction of traffic length travel occurs for bridge, by across seam
The relative movement of plate and fixed broach plate, makes the bridge expansion joint installation have length travel function.
Further preferably, described upper telescoping member also includes bearing pressing plate, rotating shaft, lower bracket bottom plate, the bearing pressure
Plate is fixed on the top of lower bracket bottom plate, and the rotating shaft sets along bridge lateral and is fixed on bearing pressing plate and lower bracket bottom plate
Between, the one end of the transverse joint plate away from fixed broach plate is fixed in described rotating shaft.So, when bridge is vertical because heavy duty is produced
During to corner, due to transverse joint plate with rotating shaft to be rigidly connected, transverse joint plate is by rotating shaft with bearing pressing plate and lower bracket bottom plate center
Hole is that axis generation is longitudinally rotated, and the bridge expansion joint installation is had longitudinal angle turning function.
Further preferably, described lower telescoping member includes bridge fixed plate and the bottom plate being placed at the top of bridge fixed plate,
The bridge fixed plate is interfixed with the transverse joint plate, and the bottom plate is interfixed with bridge fixed plate by connecting bolt,
Also, it is provided with cushioning support-saddle between described bottom plate and bridge fixed plate.So, when bridge by heavy duty, strong wind, ocean current,
Tide, earthquake effect, when horizontally rotating along pier generation, the bridge expansion joint installation passes through fixed connection spiral shell in the soleplate
Bolt, using connecting bolt as axis, produces and horizontally rotates with respect to bridge fixed plate and buffering branch, have the bridge expansion joint installation
Level angle function.
Further preferably, the bridge fixed plate is interfixed with the transverse joint plate by bolt, the upper end of the bolt
It is fixed on transverse joint plate, the lower end of the bolt passes through described bridge fixed plate and is arranged with buffer spring, the buffering elastic
The upper end of spring and the bottom of bridge fixed plate offset, and lower end and the stud base of buffer spring offset.
Compared with prior art, the advantage of the invention is that:The upper telescoping member of the bridge expansion joint installation and lower flexible
After component is cooperated by the first limit assembly and the second limit assembly, the transverse direction for being limited in bridge is relatively moved, from
And with lateral displacement function, in addition, the bridge expansion joint installation can also have length travel, longitudinal corner and level simultaneously
Corner multi-directional deflection function, using the bridge of the expansion gap device, response environment, temperature, heavy duty, strong wind, ocean current, tide,
During earthquake effect, the safety in utilization of bridge will can be more improved.
