Abstract
The utility model relates to a lead core rubber support, which is particularly suitable for being arranged between a bridge superstructure and a pier or in a building. The utility model is characterized in that a lead core is pressed in a laminated rubber bearing tightly. The utility model has the advantages that the function of the laminated rubber bearing is not influenced; the structural damage effect of a vibration load, such as an earthquake, can be reduced; thus, the bridge and the building protected.
Description
The utility model is a kind of lead core rubber support, is specially adapted to be installed between bridge superstructure and the pier, or is installed in the building, can reduce vibrating load such as earthquake to the structural damage effect, protection bridge and building.
At present, domestic bridge all adopts steel support, common laminated rubber bearing or pot rubber bearing.The major defect of these bearings is: under vibrating load effects such as earthquake, seismic force effects is on bridge construction, and structure very easily suffers seismic damage.In building, then often do not establish bearing.
The purpose of this utility model is: provide a kind of and can change bridge and building damping characteristic, alleviate the lead core rubber support of seismic forces to its destruction.
The technical solution of the utility model is achieved in that and closely is pressed into lead for retractable pencil in the preformed hole of common laminated rubber bearing, with compact heap it compressed.The voussoir that compresses by the bearing center is connected with the upper bracket plate, links to each other with lower support plate by voussoir.
The utility model has the advantages that:
1. can increase the damping of bridge and whole building structure, improve the response to earthquake of bridge and building, the energy of dissipation earthquake reduces the active force of earthquake to bridge and building;
2. do not influence its function as bearing, the fulcrum place can produce displacement on request;
3. simple in structure, easy for installation, do not need maintenance.
Fig. 1 is the utility model lead core rubber support sectional drawing.
Describe the utility model in detail below in conjunction with accompanying drawing.
