摘要： PROBLEM TO BE SOLVED: To provide superior damping effect from slight vibration such as traffic vibration to an earthquake by providing a load support part comprising alternately laminating a viscoelastic body and a reinforcing plate and an energy absorption part arranged in the hollow part of this load support part and constituting the energy absorption part from a column-shaped lead body and a viscoelastic layer. SOLUTION: A base isolation support device 1 comprises alternately laminating a viscoelastic body 5 and a reinforcing plate 6, a reinforcement mounting plate 7 having its hole for fitting dowel pin 4 is provided at both end parts of that laminating direction, and each of component members 5 to 7 is laminated and integrated by curing and adhering them. A hollow part 8 piercing through in the laminating direction is formed at the center part of the device 1, and a lead body 10 having a viscoelastic layer 9 around its body is densely sealed in this hollow part 8. Thereby, when great horizontal displacement acts on the base isolation support device 1, for example, by a large-scale earthquake, shear deformation is generated in the reinforcing plate 6 and the viscoelastic body 5, and earthquake energy is speedily absorbed by subsequent plastic deformation of the lead body 10.

摘要： PROBLEM TO BE SOLVED: To operate base isolation for the vibration of a constant value or more such as earthquake by providing a cylinder, a piston, a piston rod, an orifice passage, fluid, an energizing means for energizing the piston and an abutment means for abutting any one of the piston rod and the cylinder on the recess part of any one of a structure and foundation. SOLUTION: A lock mechanism 1 is disposed between a structure 13 and foundation 14 to support the structure 13, and used together with base isolation bearing base-isolating the structure by the shearing deformation of a horizontal direction 51. When the force of the horizontal direction 51 exceeds a constant value, force against a coil spring 35 is applied to a piston rod 6 through the roller 43 of a recess part 15, a piston 4 starts lowering, the roller 43 rolls out of the recess part 15 to release locking, base isolation bearing is shear-deformed in the horizontal direction 51. Transmission of vibration such as earthquake of the structure 13 is reduced by the shearing deformation and vibration energy is attenuated. Thus, the base isolation can be operated for the vibration such as the earthquake.

摘要： PURPOSE: To prevent the vertical stress fluctuation of a lead body and secure a pure shearing deformation by arranging a plastic deformation section made of the lead body on one side of a structure, and arranging a vertical shift mecha nism section allowing the vertical shift via the sliding between a piston body and a cylinder body on the other side. CONSTITUTION: An axial shift mechanism section 2 allowing the vertical shift via the sliding between a piston body 11 and a cylinder body 12 is arranged at the upper section of a plastic deformation section 1 mainly made of a lead body 4. When earthquake force is applied, upper and lower structures G, B are relatively displaced, then this lead damper D restricts the horizontal shift with the vertical shift mechanism section 2. A horizontal deformation is applied to the lead body 4 of the plastic deformation section 1 having small lateral rigidity, and the earthquake energy is absorbed. The displacement acceleration of the upper structure G is damped, and the relative displacement is suppressed for damping action. A large energy absorbing capability is obtained, the lead body 4 can be miniaturized, the expected energy absorption characteristic is exerted according to the design specification, and the standardization of designing can be attained.

摘要： PURPOSE:To reduce a structure vibration due to an earthquake or the like by arranging a plurality of air spring devices made of movable steel tubes sealing the high pressure air on a structure and the foundation thereof in a horizontal direction, and stacking a plurality of the devices in a vertical direction. CONSTITUTION:The horizontal vibration component of a structure foundation due to an earthquake or the like is prevented from being transmitted to a structure by the help of the shearing deformation of a laminated rubber body 4 having restitutive force. On the other hand, the vertical vibration component of the foundation is prevented from being transmitted to the structure, using stacked air spring devices 5 made of movable metal tubes 6. Furthermore, each tube 6 is internally connected to an auxiliary tank via a valve 42 having orifice function, and the vertical vibration component is attenuated with the travel resistance of the air flowing through the valve 42. In this case, if the internal pressure of the tube 6 drops below a preset value, due to an air leakage or the like, a compressor is operated to maintain the pressure at the value.

摘要： PURPOSE:To provide damping effectively over a wide range of vibration by a method wherein an elasto-plastic deformation damper section and a laminated rubber damper section are joined perpendicularly together and are connected with each other so that both the sections can be rocked freely. CONSTITUTION:An elasto-plastic deformation damper section 1 formed at least of one rod-like elasto-plastic deformation member 10 and a laminated rubber damper section 2 mainly composed of a laminated rubber body are joined perpendicularly together, and thereby a base isolation apparatus H is constructed. A regulating hole 58 is bored either to an upper bed plate 50 or an under bed plate 51 of the laminated rubber damper section 2, and a stopper member 59 is arranged in the regulating hole 58 with a specified distance maintained, and thereby the laminated rubber damper section 2 and the elasto-plastic deformation member 10 are connected with each other so that both the members can be rocked freely. In a structure as mentioned above, the laminated rubber damper section 2 undergoes relatively small horizontal vibration while the elasto-plastic deformation damper section 1 undergoes large horizontal vibration. Therefore the apparatus can give damping effect over a wide range of vibrations.
