Description
Technical Field
The utility model discloses the building shock attenuation belongs to technical field, concretely relates to direct pressurization formula rubber damping device of bolt.
Background
The earthquake brings a lot of disasters to human beings, and Wenchuan earthquake and Tangshan earthquake which are well known to be novel cause a great amount of casualties and economic losses; the earthquake threatens human beings too much, and the earthquake is likely to happen wherever people live, endangering the lives of people.
In order to reduce the damage of earthquake to buildings, building technicians provide three structures for the buildings, namely an earthquake-proof structure, a shock-insulation structure and a shock-absorption structure;
1. earthquake-resistant structure: the earthquake-resistant structure is a structure which ensures the safety of the building because the endurance strength of the building is greater than the inertia force generated by earthquake; the defects of an anti-seismic structure are that a part of buildings can be damaged or collapsed due to violent shaking in the case of a major earthquake, and the safety and post-earthquake maintenance are also a subject;
2. shock insulation structure: the seismic isolation structure is characterized in that seismic isolation measures or seismic isolation equipment are utilized to weaken and consume seismic action, so that the seismic action on the structure is greatly reduced; the disadvantage of the shock insulation structure is that the building cost is greatly increased because a shock insulation layer is required to be added;
3. shock-absorbing structure: the building shock absorption (structure energy dissipation shock absorption technology) is that energy dissipation devices are arranged at certain parts (such as supports, shear walls, connecting joints or connecting pieces) of a structure, and the energy input into the structure by the earthquake is dissipated or absorbed by the devices through friction, bending (or shearing, torsion) and elastic-plastic (or viscoelasticity) hysteresis deformation so as to reduce the earthquake reaction of the main structure, thereby avoiding the structure from being damaged or collapsed and achieving the purpose of shock absorption control; the existing damping devices mainly comprise three types, namely, an oil pressure damper for damping, an unbonded support (damping lacing wire) and a bolt indirect pressurization damping damper (a cantilever type pressurization method);
at present, a plurality of domestic damping energy consumption devices are oil pressure dampers for damping, and the oil pressure dampers for damping have the defect of high price, thereby increasing the building cost; the countries such as Japan use the unbonded support more, its disadvantage is that the steel core material produces the plastic deformation after the earthquake, the lacing wire loses the elasticity, need to change the steel core material, this has caused the result that the maintenance cost increases by a wide margin after the earthquake; in addition, the price of the unbonded support itself is also relatively high, and the construction cost is also a problem. The bolt indirect pressurization shock absorption damper has the defect that the bolt is indirectly pressurized through the steel plate cantilever beam, so that the friction force generated is relatively small, and the bolt indirect pressurization shock absorption damper cannot be applied to medium and large buildings and is generally applied to micro buildings.
