Description
Technical field
The utility model is related to a kind of supporting bridge devices, and in particular to a kind of bridge integral type lead for retractable pencil isolation rubber branch
Seat.
Background technology
Earthquake is a kind of sudden, destructive natural calamity, he constitutes a serious threat to human society.How work is reduced
The problem of damage that journey structure is subjected in earthquake is one real and great.Lead rubber bearing isolation property ten
Divide protrusion, there is the advantages that load-carrying properties are good, and horizontal rigidity is moderate, and energy dissipation capacity is strong, be at home and abroad widely used in bridge
Shock insulation.
Existing highway bridge lead rubber bearing, such as Fig. 3, usually by the interior junction steel plate of upper and lower ends, intermediate laminate steel
Plate and the vulcanization of rubber are bonded to support body, then by bolt upper Sub-sealing Course steel plate are connected with interior junction steel plate integral.
But this lead rubber bearing needs 4 steel plates, and needs bolt that it is assembled up, and assembly process is complicated, cost
It is higher.In addition lead rubber bearing requirement flatness is higher, and steel plate is cut by plane steel plate, and work in-process is special
It is not for big planar dimension steel plate, it is difficult to ensure that its surface smoothness, 4 steel plate flatness add up and bearing can be caused integrally to put down
Whole degree is poor.
It is Patent No. CN201620406567.3, entitled《A kind of entirety is rubber earthquake isolation support》Utility model patent
Although reducing the flatness of bearing, for the patent only with a lead for retractable pencil stick, the diameter of lead for retractable pencil stick is excessive, influences bearing
Stability and reset capability, and patent rubber basin edge is small with the contact surface area of upper Sub-sealing Course steel plate, influences bearing entirety
Caking property, basin edge easily separate at outer edge with upper Sub-sealing Course steel plate.
Utility model content
The technical problems to be solved in the utility model is：A kind of bridge integral type lead rubber bearing is provided, with gram
Take the above-mentioned deficiency present in prior art.
To solve above-mentioned technical problem the technical scheme adopted by the utility model is that：A kind of bridge integral type lead for retractable pencil shock insulation rubber
Glue bearing, including upper sealing steel plate, Sub-sealing Course steel plate and the support body being bonded between upper and lower sealing steel plate, the branch
Seat body and upper and lower sealing steel plate entirety sulfidization molding, support body is by laminated steel plate and rubber by vulcanizing molding bonded；
The rubber support is uniformly equipped with 4 lead for retractable pencil sticks, and the lead for retractable pencil stick is mounted in the lead for retractable pencil hole of rubber support, lead for retractable pencil
Counterbore is equipped on the outside of the corresponding upper and lower sealing steel plate of hole upper and lower port, the lead for retractable pencil cover board for sealing lead for retractable pencil stick is installed in counterbore；
The upper and lower sealing steel plate surface Nian Jie with support body is equipped with circular or rectangular boss, in support body,
Lower face is basin with boss corresponding matching, the transition face that basin periphery the is formed edge Nian Jie with upper and lower sealing steel plate to
Extend to form flange outside.
Further：The cross-sectional shape of the flange is triangle, and hypotenuse is straight line or circular arc line.
Further：The counterbore is circular or rectangle, and the lead for retractable pencil cover board is corresponding circular or rectangular steel plates, the steel
It is connected by screw bolts between plate and upper Sub-sealing Course steel plate, glue is Nian Jie or welding.
The upper and lower sealing steel plate and support body are circular or rectangle.
Due to using the above structure, compared with prior art, the bridge integral type lead for retractable pencil isolation rubber branch of the utility model
Seat has the advantages that：
1. since the utility model includes upper and lower sealing steel plate and the bearing sheet being bonded between upper and lower sealing steel plate
Body, the support body and upper and lower sealing steel plate entirety sulfidization molding, bearing core pass through vulcanization by laminated steel plate and rubber
Molding bonded, entire bearing are not required interior junction steel plate, that is, 4 steel plates and bolts assemblies are not required, and assembly process is simple, into
This is low.
2. since the utility model bearing need not cut 4 steel plates, and bearing core and upper Sub-sealing Course steel plate it
Between using sulfidization molding technology, integral smoothness is good.
3. the utility model bearing is uniformly equipped with 4 lead for retractable pencil sticks, lead for retractable pencil stick is mounted in the lead for retractable pencil hole of rubber support, has
The phenomenon that effect avoids since single lead diameter of mandrel is excessive and influences the stability and reset capability of bearing.
4. the upper and lower sealing steel plate of the utility model surface Nian Jie with bearing core is equipped with circular or rectangular boss, bearing
The upper and lower end face of core is the basin of shape and boss corresponding matching, and basin periphery forms transition face, transition face and upper and lower sealing
The edge of steel plate bonding extends outward to form flange, and the cross-sectional shape of flange is triangle, and hypotenuse is straight line or circle
Camber line can further increase rubber basin edge and the contact surface area of upper and lower sealing steel plate, improve bearing entirety Cohesion reliability,
Bearing core is made to be not easy to separate with upper and lower sealing steel plate.
5. the lead for retractable pencil cover board of the utility model is mounted in counterbore, spiral shell is used between lead for retractable pencil cover board and upper and lower sealing steel plate
Tether connect, glue bonding or welding, so as to by lead for retractable pencil stick both ends seal, effectively prevent lead leakage pollution environment.
