Abstract
The inhaul cable damping support saddle of elevated bridge.That there are shock insulation frequency bands is narrow for traditional inhaul cable damping support saddle, restraining ability is insufficient, in middle or small earthquake magnitude, the upper and lower support of inhaul cable damping support saddle is easy to happen opposite sliding, and there is also install not convenient enough problem in the fixed form of drag-line and upper and lower support.The utility model composition includes upper bracket plate (1), upper bracket plate is connect with lower support plate (8) by drag-line (3), upper bracket plate, lower support plate middle section respectively there is one group of pin hole, shear pin (10) sequentially passes through the pin hole of the pin hole of upper bracket plate, lower support plate, space between upper bracket plate, lower support plate is filled with spherical crown liner plate (5), plane tetrafluoro slide plate (4) is accompanied between the upper surface and upper bracket plate of spherical crown liner plate, and spherical surface tetrafluoro slide plate (6) is accompanied between the lower surface and lower support plate of spherical crown liner plate.The utility model is applied to the inhaul cable damping support saddle of elevated bridge.
Description
Technical field:
The utility model relates to a kind of inhaul cable damping support saddles of elevated bridge.
Background technique:
Inhaul cable damping support saddle be it is a kind of by friction effectively consumption earthquake occur when seismic wave to bridge structure generate
Act on energy and the shock mount using the drag-line limitation excessive relative displacement of pier beam.There are shock insulation frequencies for traditional inhaul cable damping support saddle
With narrow, restraining ability is insufficient, in middle or small earthquake magnitude, the upper and lower support of inhaul cable damping support saddle is easy to happen opposite sliding, and
There is also install not convenient enough problem in the fixed form of drag-line and upper and lower support.
Utility model content:
In order to overcome the above problem of the existing technology, the purpose of the utility model is to provide a kind of drawings of elevated bridge
Rope shock mount.
Above-mentioned purpose is realized by following technical scheme:
A kind of inhaul cable damping support saddle of elevated bridge, composition includes: upper bracket plate, the upper bracket plate and undersetting
Plate by drag-line connect, upper bracket plate, lower support plate middle section respectively there is one group of pin hole, shear pin sequentially passes through
The pin hole of the pin hole of support plate, lower support plate, the pin hole of upper bracket plate is the truncated cone-shaped hole of big upper and lower small mouth, institute
One end of shear pin stated is big, and another end is small, and the space between upper bracket plate, lower support plate is filled with spherical crown liner plate, institute
Plane tetrafluoro slide plate, the following table of the spherical crown liner plate are accompanied between the upper surface for the spherical crown liner plate stated and the upper bracket plate
Spherical surface tetrafluoro slide plate is accompanied between face and the lower support plate, the anchor bolt being equipped in the lower support plate is described
Drag-line two ends be each passed through fixed plate after connect with abnormity nut, the outer surface of the abnormity nut is rotary table
Shape, the groove shapes of the fixed plate be fixed plate identical as abnormity nut shape, described respectively with upper bracket plate, lower branch
Seat board is connected by fixing bolt.
The utility model has the beneficial effects that
The utility model is suitable for highway bridge, railroad bridge, urban elevated bridge and various has large-scale suspension knot
The building of structure.Due to making support show as the structure type of hold-down support in normal use using shear pin and drag-line,
Drag-line does not work at this time；When earthquake occurs, when the horizontal force of support transmitting is greater than the shear strength of shear pin, shear pin
Be broken at sheared edge position, on the one hand consume part seismic energy and protect superstructure, on the other hand make support by
Hold-down support becomes movable bearing support, and when the upper and lower seat board displacement of support is more than certain limit, drag-line plays the role of limiting buffer, and
Guarantee upper and lower seat board reliable reset after shaking.
The inhaul cable damping support saddle of the utility model remains that ball shaped steel bearing/pot bearing vertical bearing capacity is big, horizontal position
Big advantage is measured in shifting, and its friction isolation function and drag-line limit function is dexterously incorporated in a support, simple installation.
By reasonably designing the parameter of drag-line, make support that can not only meet the service performance under Static behavior, and make in macroseism
With the lower stress that can effectively reduce anchor block, the relative displacement between pier beam is limited.Therefore, make bridge system normal use item
Clearly hold-down support is used under part and movable bearing support stress is clear, and inhaul cable damping support saddle has under small shake and big shake effect
Accurate this structure mechanical model is imitated, the application of design based on performance criterion is conducive to.
For the utility model come stay guy by the way of fixed plate and abnormity nut, this is a kind of novel fixation side
Formula, with other existing fixed forms, short construction period, structure is simple, easy for installation.Fixed plate is first passed through into drag-line when installation
Then abnormity nut is connected to drag-line end again by end, be finally fixed on upper bracket plate, in lower support plate with fixing bolt.
Detailed description of the invention:
Attached drawing 1 be the utility model along bridge to structural schematic diagram.
Attached drawing 2 is the structural schematic diagram of the utility model direction across bridge.
In figure, 1 is upper bracket plate, and 2 be abnormity nut, and 3 be drag-line, and 4 be plane tetrafluoro slide plate, and 5 be spherical crown liner plate, and 6 are
Spherical surface tetrafluoro slide plate, 7 be fixed plate, and 8 be lower support plate, and 9 be anchor bolt, and 10 be shear pin, and 11 be Boards wall bolt.
Specific embodiment:
Embodiment 1:
A kind of inhaul cable damping support saddle of elevated bridge, composition includes: upper bracket plate, the upper bracket plate and undersetting
Plate by drag-line connect, upper bracket plate, lower support plate middle section respectively there is one group of pin hole, shear pin sequentially passes through
The pin hole of the pin hole of support plate, lower support plate, the pin hole of upper bracket plate is the truncated cone-shaped hole of big upper and lower small mouth, institute
One end of shear pin stated is big, and another end is small, and the space between upper bracket plate, lower support plate is filled with spherical crown liner plate, institute
Plane tetrafluoro slide plate, the following table of the spherical crown liner plate are accompanied between the upper surface for the spherical crown liner plate stated and the upper bracket plate
