Description
Technical field
The utility model belongs to field of track traffic, is related to railway bed accessory, specially it is a kind of it is floating ballast bed in it is adjacent
The shear hinge of Transfer of Shear between floating plate.
Background technique
A large amount of engineering practices of field of track traffic prove that floating plate road bed technique is existing most effective track vibration-reducing drop
It makes an uproar one of technology, especially in subway and urban light rail, this technology, which has been obtained, to be widely applied.In floating plate railway roadbed
In, forces acted on rail and difference in non-floating solid concrete roabed, rail can because the elastic changing of the relative positions at adjacent panels end and additionally by
There is the hidden danger for leading to broken rail in power.Therefore in existing floating ballast bed structure, shear hinge has become one that floating plate plate is connect with plate
Indispensable important safety component, is the structure important component of the Transfer of Shear between adjacent floating plate, it can be with
It shares rail and is crossing over the shearing born at plate stitch, make compatible deformation between plate and plate.Existing shear hinge presses its working position
It sets and is broadly divided into overhead and two kinds of middle, middle shear hinge is located at the middle part of adjacent floating plate body, reasonable stress, but
Replacement not easy to repair, the application of overhead shear hinge is more in practice；Overhead shear hinge is located above floating plate body, both ends difference
It is fixed on adjacent floating plate, is adapted between adjacent floating plate along the longitudinally opposite displacement of rail, but strictly limit two
Person along rail laterally with vertical relative displacement, replace very convenient by maintenance.But it is found in application process, existing overhead
For shear hinge since stress point is higher, the moment of flexure born in the course of work is larger, therefore the shearing resistance in overhead shear hinge occurs
The new problems such as plug fatigue fracture or fixing bolt fracture.How itself damage in the overhead shear hinge course of work is avoided
Wound becomes a problem of puzzlement industry.
Utility model content
The purpose of the utility model is to overcome drawbacks described above, and the ability for providing a kind of receiving moment of flexure is stronger, can be effective
Avoid the bending resistance square shear hinge of self-inflicted injury.

The two is assembled together by dress abdicating through hole；Alternatively, the anchoring assembly includes keeper, anchor connection plate and anchor rib, anchoring
Muscle is fixed on anchor connection plate, and keeper is equipped with installation through-hole, and corresponding anchor connection plate is equipped with screw hole；Using tight
Firmware passes through the installation abdicating through hole being arranged on the installation through-hole and shearing resistance element being arranged in keeper and sets on anchor connection plate
The screw hole cooperation set, three is assembled together, and the keeper is located above shearing resistance element, is above set elastomer and is located at keeper and resists
It cuts between element, underlying elastomer is between anchor connection plate and shearing resistance element.
The shearing resistance element includes the shear connections stick that connecting plate is respectively set in shear connections plate, shear connections beam or both ends
Etc. specific constructive forms；The installation abdicating through hole is arranged on shear connections plate, be perhaps arranged on shear connections beam or
It is arranged on the connecting plate of shear connections stick.It is noted that shear connections plate can be by high-strength plates such as steel plate, stainless steel plates
Material is process；Shear connections beam can be made of materials such as I-steel, channel steel or steel pipes；Shear connections stick can be by rod iron etc.
Material is made.
It to be backing plate made of rubber or elastane that elastomer and underlying elastomer are set on described.In addition,
Underlying elastomer is pricked bad in order to prevent, can also include protection backing plate, the protection in the utility model bending resistance square shear hinge
The lower section of underlying elastomer is arranged in backing plate.
The utility model bending resistance square shear hinge is overcome existing floating by setting elastomer and underlying elastomer on adding
In ballast bed structure, flexible backing plate bearing under rail, flexible vibration isolator bearing under floating plate has only and is arranged between adjacent floating plate
Shear hinge using rigidity cooperation, when work, bears the defect of very big moment of flexure, and it is practical at this above to set elastomer and underlying elastomer
Novel bending resistance square shear hinge bears to realize resilient protection and shear energy dissipation when moment of flexure, therefore the utility model can be effectively prevented
Itself damage occurs for bending resistance square shear hinge, and the ability for bearing moment of flexure is stronger；On the other hand, due to above setting elastomer and underlying bullet
Property body can provide certain flexible deformation when the utility model bending resistance square shear hinge bears moment of flexure, therefore in floating ballast bed structure
