Description
Technical field
The invention belongs to architectural engineering technical field of isolation, relate generally to chute-type tensile shock isolation device.
Background technology
Rubber support seismic isolation technology is the seismic isolation technology of current comparative maturity.But due to bearing inner rubber and and steel plate it
Between connect for bonding, when skyscraper is subject to Vertical Earthquake Loads, or when bearing occurs greater level shear displacemant, or building is high
Wide than larger when, the easy tension of bearing, and rubber support tension easily occurs the tear failure of rubber layer and steel plate, and then impact bearing
Horizontal seismic isolation performance, or directly result in building occur overturning.
According to standard GB/T 50011-2010《Seismic design provision in building code》Requirement, rubber earthquake isolation support Chinese ground
The horizontally and vertically earthquake of shake acts on down simultaneously, and tension not should be greater than 1MPa.But under violent earthquake effect, middle and high layer is built
The rubber earthquake isolation support built may withstand greater than the tension of restriction, because the resistance to tension of rubber earthquake isolation support is limited, therefore
Its range of application is restricted.In order to improve the resistance to tension of rubber earthquake isolation support, Chinese scholars have carried out various researchs, day
This scholar develops orthoscopic sliding support, and it is made up of the track of two orthogonal directions, back and forth can slide along rail junction
Dynamic, thus the vibrations of any direction can be isolated, there is very big vertical compression ability and breakout capacity simultaneously, but this bearing chi
Very little huge, simultaneously high to the friction requirements of track, production cost is high.Chinese scholar proposes inside prestress wire
Prestress rubber earthquake isolation support, arranges the construction measure of appropriate vertical reinforcement around shock isolating pedestal, and this tensile measure is propping up
Seat occurs prestressing force twisted wire and reinforcing bar during large deformation will produce irrecoverable deformation, will be unfavorable for the horizontal seismic isolation of bearing.
In a word, there is construction complexity in existing tension technology, and installation cost is high, and the level that tensile device affects bearing is firm
Degree, the problem of the isolation property of impact bearing.Therefore, rubber earthquake isolation support resistance to tension deficiency becomes skyscraper shock insulation field
Problem demanding prompt solution.
Content of the invention
It is an object of the invention to provide a kind of solve rubber earthquake isolation support not enough asking of resistance to tension in skyscraper
Topic, and simple structure, the chute-type tensile shock isolation device that small, resistance to tension is strong.Be applied to the larger building of depth-width ratio or
It mostly is and easily make bearing that the building structure of tension occurs under geological process.This device can reduce the vertical effect of earthquake or wind load
The infringement to support body for the effect, improves the anti-pulling resistance to capsizing of building.
For achieving the above object, the technical solution used in the present invention is：
Chute-type tensile shock isolation device, this earthquake isolating equipment includes connecting plate 1, support body 2, tension member 3.Connecting plate 1
It is made up of coulisse 4 and cover plate 5 two parts, coulisse 4 is provided with chute 6；Between coulisse 4 and support body 2, coulisse 4
All it is connected by high-strength bolt 11 between cover plate 5, the cantilever of tension member 3 is placed in chute 6, when support body 2 occurs edge
During the shear displacemant of the major axes orientation of geological process, tension member 3 slides in chute 6, and parallel with shear displacemant direction two
Root tension member 3 is radially extracted out along support body, and vertical with shear displacemant direction two tension members 3 are along connecting plate 1 side
Edge slides, and is always maintained at vertical state, provides effective pull for earthquake isolating equipment, strengthens the resistance to tension of earthquake isolating equipment.
Described tension member 3 radially can be extracted out along support body 2, again can along connecting plate 1 boundary slip, therefore, when
When seat main body 2 occurs shear displacemant, tension member 3 will be always maintained at vertical state, provide effective pull for earthquake isolating equipment.
The distance between the lower surface of described upper cover plate 6 and upper surface are less than the height of tension member 4, in geological process
Under, the vertical decrement of earthquake isolating equipment is not result in that tension member 4 is pressurized, thus ensureing that tension member 4 can be with support body 3
Motion.
The edge of chute 6 is provided with limiting plate 8, and limiting plate 8 length and width is sufficient for support body 2 and large deformation occurs
When tension member 3 slide displacement.
The cantilevered distal end of tension member 3 is provided with limited block 9, therefore, tension member 3 in support body 2 deformation process
Will not extract out completely from chute 6, thus ensureing that tension member 3 can provide effective pull always.
Described support body 2 is laminated rubber damping bearing, lead rubber laminated bearing or other rubber earthquake isolation supports.
Described connecting plate 1 and tension member 3 are steel material.
Compared with prior art, the present invention has the advantages that：
When geological process undersetting main body occurs shear displacemant, tension member slides in chute, and tension member is by one
Directly it is in vertical state, if there being tension, tension member provides pulling force, thus protecting support body from damage；This device structure
Make simple, small, resistance to tension strong it is adaptable to high-rise shock-insulation building.
The invention will be further described below in conjunction with the accompanying drawings.
