Abstract
The utility model relates to the technical field of building shockproof and shock resistance, which is a sandwich rubber anti-vibrating support used in the engineering of building structure or the bridge engineering. The sandwich rubber anti-vibrating support is composed of a lower closing plate, an upper closing plate, as well as the sandwich rubber lying between the lower closing plate and the upper closing plate. A sandwich steel plate is arranged between the sandwich rubber, the support is provided with a hollow mid span provided with a lead cord. Except for making the support have the better reset ability and durability in the anti-vibrating process, the support can be made to have better fatigue resistance under the cycle of plastic deformation. The amortization of support is increased, and the consumption of the energy generated by the vibration of the support to the environment is enhanced.
Description
Technical field
The utility model relates to shockproof, the anti-seismic technology field of building, is a kind of laminated rubber vibration isolation bearing that is applied to structural engineering or bridge engineering.
Background technology
Earthquake is a kind of natural calamity, and strong earthquake meeting brings huge disaster to the mankind, comprises casualties and economic loss.Historically, China's earthquake disaster occupies first of the world, is characterized in that frequency height, earthquake magnitude are big, it is wide to distribute.20th century, China took place more than six grades inferior surplus the earthquake 600.China 1/3rd above territories, big and medium-sized cities more than half are positioned at seismic fortification intensity 7 degree and the above area of 7 degree.At present, the earthquake of China is still very active, and 8 earthquakes more than 7 grades and more than 40 earthquake more than 6 grades have since nineteen ninety-eight taken place, and in February, 2003,6.8 grades of earthquakes of Bachu, Jiashi caused 1,300,000,000 yuans of direct economic losses.The earthquake that Iran's crust nurse takes place at the beginning of 2004 causes nearly 50,000 people's death.
Seismic isolation technology is comparatively effective in the world novel earthquake resistant engineering new technology.The isolation structure system is by being provided with the shock insulation layer, structure is divided into superstructure, shock insulation layer and substructure three parts, seismic energy passes to the shock insulation layer via substructure, after being absorbed and consumed main seismic energy by the earthquake isolating equipment of shock insulation layer, only has the small part energy to pass to superstructure.The peak acceleration reaction that the earthquake zone shock-insulation building records in U.S. Northridge violent earthquake (1994) and the Japan Kobe violent earthquake (nineteen ninety-five) shows: isolation structure top layer acceleration response peak value only is 20% (isolation structure 198Gal, non-isolation structure 965Gal) of non-isolation structure.This acceleration response contrast record that is the shock insulation of surveying the earliest in the world and non-isolation structure under shake effect has doughtily confirmed that the isolation structure system is the new structure system of current a kind of comparatively desirable earthquake disaster mitigation.
Rubber earthquake isolation support is an earthquake isolating equipment representative in the seismic isolation technology, and it has very big vertical bearing capacity, and its horizontal rigidity is less, and the horizontal limeit displacement capabilities is bigger.Simultaneously, shock insulation rubber bearing has reduction with good ability and endurance quality.
During earthquake, the energy that passes to structure for the dissipation earthquake ensures the safety of structure, can adopt metallic lead to surrender and reach above-mentioned requirements.Plumbous yield point is low, recovers after can surrendering at ambient temperature, crystallization and growth course as a result again, and under plastic strain circulates good anti-fatigue performance is arranged.
Summary of the invention
The purpose of this utility model is to provide a kind of laminated rubber vibration isolation bearing with new structure, except making bearing in the shock insulation process, have better reset capability and the endurance quality, can also make bearing under the plastic strain circulation, have good anti-fatigue performance, increase the bearing damping, and improve the consumption that bearing shakes the energy that is produced to external world.
The utility model is realized by following proposal: this laminated rubber vibration isolation bearing is made up of the laminated rubber 6 that descends shrouding 1, upper sealing plate 9 and be positioned between the two, be provided with sandwich clad steel 5 between the laminated rubber 6, be characterized in being provided with in the bearing hollow mesopore 10, be provided with lead for retractable pencil 3 in the hollow mesopore 10, plumbous yield point is low, recover after can surrendering at ambient temperature, crystallization and growth course as a result again, and under plastic strain circulation, good anti-fatigue performance is arranged, and the energy that can effectively absorb external shock and produced.
The above-mentioned laminated rubber 5 outer outpacking rubbers 7 that are provided with.
Following shrouding 1, sandwich clad steel 5, laminated rubber 6, outpacking rubber 7 and upper sealing plate 9 are for vulcanizing in aggregates by high temperature, high pressure, the hollow mesopore design of bearing is to provide the expansion space for sulfidation, vulcanized quality in the sulfidation can be guaranteed like this, and the stable of lead for retractable pencil performance can be guaranteed.
Above-mentioned shrouding 1 down and upper sealing plate 9 are provided with some coupling bolt holes 4, are used for bearing is fixed in building.
The two ends of the plumbous heart are fixed with cover plate 2, and cover plate 2 is provided with hexagon socket head cap screw 8, is used for lead for retractable pencil is sealed.
Between the sandwich clad steel 5 several layers laminated rubber 6 can be arranged.
The overall performance of the type bearing is good.Rubber in the rubber earthquake isolation support adopts the soft natural rubber, and rigidity is 67% of middle hardness rubber only after the surrender of neoprene bearing, makes the cycle stretch-out of isolation structure, and the reaction of superstructure peak acceleration reduces.
Compared with prior art, advantage of the present utility model is: (1) makes bearing under the plastic strain circulation good anti-fatigue performance be arranged; (2) increased the damping of bearing; (3) improve the consumption that bearing shakes the energy that is produced to external world; (4) stable performance of lead for retractable pencil, plastic strain circulation back lead for retractable pencil performance variation is little; (5) structures isolation effect is effective.
