Description
Technical field
The utility model relates to a kind of shock insulation house that is applicable to the band bead-fine sand-cementitious material composite bed of villages and small towns buildings, belongs to a kind of novel practical, simple, economic, the cheap base isolation house that is applicable to village-town house.
Background technology
Base isolation is between building superstructure and basis, to set up the very little supporting element of horizontal rigidity, makes superstructure prolong natural vibration period, away from the predominant period of geological process, thereby alleviates earthquake effect on upper structure.At present fairly perfect for the research of base isolation, earthquake isolating equipment is various, and the method for designing of architectural vibration-insulation is also ripe and write standard.And the research for rolling shock insulation both at home and abroad is still few, and what domestic document related generally to mostly is the rubber pad earthquake isolating equipment, and research also is tending towards perfect.There have been many people to propose some rolling shock insulation devices at present, but all just done initial theory analysis and experimental study, further do not related to the optimization analysis of relevant parameter.
The rolling shock insulation technology that development in recent years is got up is between basis and superstructure, spin to be set mostly, and the last lower support surface of spin is made cambered surface; The dual-side of base plate has the spring camming of a particular design respectively, and under normal operation, cam fully compresses spring and gives basic lateral-supporting; When earthquake is arrived; Thereby geological process makes the foundation motion release cam, and the spring camming is started working, and each relevant parameter of optimal design can reduce the transmission of earthquake to superstructure greatly.Though this technology has overcome the defective of rolling shock insulation technology to a certain extent.But the manufacturing and the construction technology of its high relatively cost, complicacy not too are suitable for vast villages and small towns of China and low-rise building.And in all previous earthquake, the destruction of villages and small towns building is the most serious.Therefore, rolling shock insulation device and application technology thereof that research and development are economical, suitable, cheap have important theoretical meaning and social economic value.
