Description
Technical Field
The utility model belongs to the technical field of seismic isolation supports, and particularly relates to a novel bridge sliding seismic isolation support.
Background
China is one of the countries with the strongest earthquake activities and the most serious earthquake disasters in the world. The shock insulation rubber support is widely applied to various shock insulation and reduction fields, adopts the excellent bonding of the alternate superposition of the multilayer steel plates and the multilayer rubber, has a series of advantages of good horizontal performance, damping coefficient, vertical performance, vertical bearing capacity and the like, and is applied to various house buildings, highway bridges and structural reinforcement. However, the vibration isolation rubber support is damaged when an earthquake occurs or the vibration isolation rubber support is used for a long time, and the old support needs to be replaced without influencing the upper structure. At present general change mode is the back that shifts out old shock insulation rubber support, installs new shock insulation support immigration original mounted position again, will meet at this moment because the reason that upper portion load was received on whole shock insulation layer and have the space that subsides and lead to shock insulation layer erection support than original meeting reduce, new shock insulation support can't move into the problem in the original support installation space, leads to the unable installation of new support.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the existing shock insulation support has insufficient vertical replacement space due to pressure settlement during replacement, and provides a novel bridge sliding shock insulation support in order to overcome the defects.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a novel bridge slides and subtracts isolation bearing, including the rubber body, rubber body upper end is connected with the roof, and the lower extreme is connected with the bottom plate, is located to be provided with a plurality of support locking part between the outer last roof of rubber body and the bottom plate, support locking part including the lower connector that is the setting of L type, the horizontal segment and the bottom plate of lower connector are connected through the fastener, and sliding connection has last connector on the vertical section of lower connector, it is connected with last roof through the fastener to go up the connector upper end.
Furthermore, an eccentric rotating wheel is arranged in a vertical section of the lower connecting body, a rotating handle is connected to the outer surface of the eccentric rotating wheel, the upper connecting body is arranged in a C-shaped mode, a horizontal waist-shaped groove is formed in the vertical section of the upper connecting body, and an eccentric shaft of the eccentric rotating wheel is located in the waist-shaped groove.
Furthermore, vertical guide rods are arranged on the upper surface of the horizontal section of the lower connecting body, guide holes are formed in the upper connecting body opposite to the guide rods, and the guide rods are movably inserted in the guide holes.
Further, the support locking part is provided with at least three.
Furthermore, a plurality of fabrication holes are formed in the upper top plate.
When the shock insulation support works, a constructor firstly applies pressure to the whole shock insulation support through an external pressure device to pre-compress the whole shock insulation support so that the height of the whole support is reduced, the eccentric rotating wheel is rotated to enable the upper connecting body to abut against the lower surface of the upper top plate, the upper connecting body is connected with the upper top plate, the lower connecting body is connected with the lower bottom plate, the whole support keeps certain pressure, pre-pressure is removed after connection is completed, the whole support is moved to an installation position, the upper connecting body and the lower connecting body are disassembled, the original height of the whole support can be recovered, and therefore the problem of insufficient vertical space during replacement is effectively solved.
Compared with the prior art, the utility model has the beneficial effects that: due to the fact that the locking part is supported, the problem that the vertical replacement space is not enough due to pressure settlement when the shock insulation support is replaced is solved, efficiency of the shock insulation support is improved when the shock insulation support is replaced, and the shock insulation support is suitable for industrial production and has strong practicability.
