摘要： PURPOSE:To make effective base isolation and vibratory suppression of horizontal and vertical vibrations by installing consolidatedly a horizontal tremor absorbing part to absorb horizontal tremors, a vertical vibration absorbing part to absorb vertical tremors, a restraining member for deformation in the vertical and horizontal directions, and a vertical vibration damping member. CONSTITUTION:A tapered portion 12a of a steel rod is formed from a restraining member 12 for deformation in the vertical and horizontal directions. A clearance 14 is provided between an upper flange 8 of a horizontal vibration absorbing part 5 situated under and a taper hole 13 penetrating a lower flange 10 of a vertical vibration absorbing part 6. Horizontal deformations exceeding this size are restrained by the clearance 14. Horizontal vibrations are mostly absorbed by the absorbing part 5 situated under. The vertical vibration of the ground is absorbed by the absorbing part 6 to the extent of the clearance 14. The resonance of the absorbing part 6 for the vertical vibration is damped by a damping member 15. Thereby base isolation and vibratory suppression of the structure can be made effectively using a device in which the prevention of seismic tremors and environment vibrations is incorporated consolidatedly.

摘要： PURPOSE:To obtain vibration resistant rubber capable of coping with share deformations in the diagonal direction to a satisfactory extent by alternately laminating radially bored metal plates with rubber, changing the distance from the center for every plate and integrally molding them in such a way that rubber holes are continuously formed. CONSTITUTION:Vibration resistant rubber 1, which are interposed between a foundation and a building, are alternately laminated with metal plates 2 which vary with a distance from the center for every plate and have radially bored holes 2a and rubber 3 in such a way that the rubber 3 is formed continuously and integrally through the holes 2a. In addition, the holes 2a at the corners formed in the shape of smoothly curved surface, thereby preventing the concentration of stress in the corners and protecting the rubber from rapture. This compensates the bonding between the metal plates 2 and the rubber 3 at their interface. This construction makes it possible to obtain vibration resistant rubber capable of coping with rolling during earthquake to a satisfactory extent.

摘要： PURPOSE:To improve durability by forming the elastic plate of an earthquakeproof device consisting of the lamination of the elastic plate and the metal plates from silicone rubber. CONSTITUTION:An earthquakeproof device consists of a plurality of iron plates 13, a plurality of silicone rubbers 14, and a flange 15, and the silicone rubber in liquid state is allowed to flow into between the laminated metals, and hardening adhesion is carried out at a room temperature. Since the silicone rubber is used for an elastic plate, the durability such as the temperature dependence and the frequency dependence of the dynamic characteristics and the variation of the creep characteristic for a long period can be improved in comparison with the case where natural rubber is used.

摘要： PROBLEM TO BE SOLVED: To perform aseismatic reinforcement at a site without flawing a statue by erecting a support inside a decoration such as a hollow statue formed of gypsum or the like, in the state of being connected to a supporting part (base seat), and fitting a filler therein to fix the support. SOLUTION: A support 12 is inserted inside a statue 1 formed of hollow material such as gypsum and installed at a projecting part 3a or the like in a high place of the building wall surface 3 of a church or the like, and erected on a fixed base and fastened. A filler 13 such as foam urethane is filled in the statue 1 to integrate the support 12, and the fixed base 10 is fixed to the projecting part 3a by bolts 11 so as to prevent the generation of such stress concentration as to destroy the statue 1 even though large earthquake inertia force acts thereon. In case of a relatively large statue, the support 12 is made a steel column provided with a large number of studs reinforcements are arranged, and fiber reinforced concrete or the like is filled to prevent the statue from falling or being damaged in case of an earthquake or the like. Aseismatic reinforcement of the statue 1 can therefore be performed positively at a site.

摘要： PROBLEM TO BE SOLVED: To prolong the vibratory period even against a relatively light-weight structure by a laminated rubber type vibration isolation mechanism. SOLUTION: Two kinds of the first vibration isolation support structure 2A always receiving the load of a structure and the second vibration isolation support structure 2B receiving the load of the structure only when a horizontal displacement larger than a specified range arises, are prepared in a laminated rubber type vibration isolation support structure to support the structure. The second vibration isolation support structure is composed of a laminated rubber body 15 fitted to a foundation 1 and a restrictive member 17 fitted to the structure body 10. A protrusion 20 is formed at the upper part of laminated rubber body 15 and conical recesses 22 provided with a slope 22a corresponding to the slope 20a of the protrusion, are formed in the restrictive member 17.

摘要： PURPOSE:To prevent the excitation of vertical vibration by composing an isolation device of a vibration isolation part and a vibration proof part with a damping part which is provided with an attenuation mechanism filled with an electric viscous fluid in a casing having an electrode. CONSTITUTION:An isolation pat 5 of an isolation device 7 attenuates horizontal vibration to be input into a floor 13 by changing the vibration into a long cycle of vibration with a multiple stage laminated rubber. A vertical movement vibration-proof part 6 of the isolation device 7 controls the voltage applied across electrodes 28 and 29 against vertical vibration which is input into the floor 13 and adjusts equivalent viscosity of an electric viscous fluid in a casing 26 and the vertical movement of a piston of a piston rod submerged in the electric viscous fluid, thereby controlling an attenuation performance.
