Description
Technical field:
The utility model relates to a kind of three-dimensional shock isolation supports on building.
Background technique:
On May 12nd, 2008,8. 0 grades of earthquakes occurred for Wenchuan County in Sichuan, showed that Wenchuan is big according to the information announcing of earthquake-stricken area
Casualties in earthquake, caused by being mostly due to the house collapses such as factory, office building, school, house, it is possible thereby to see
Out, as China's Urbanization Construction develops, the density of population of cities and towns aggregation is also being risen with it.Therefore, the police of Wenchuan earthquake
One of show, it should exactly focus more on the research application of building damper.
Predominantly stay in the shock insulation of simple horizontal direction to the research of seismic isolation technology both at home and abroad at present, to and meanwhile realize multidimensional
The research of horizontal seismic isolation and vertical earthquake isolating, which is not much, to be seen.It can be seen that vertical seismic action by a large amount of earthquake record statistical result
Peak accelerator and horizontal earthquake acceleration ratio 1/2~2/3, and vertical component of acceleration meets or exceeds water
The earthquake record of flat component of acceleration.And a large amount of earthquake show Vertical Earthquake Loads sometimes even over horizontal earthquake action,
Its influence to structure can not be ignored.
With the raising that metropolitan subway construction increasingly increases and people's living standard requires, in order to efficiently use ground
Iron periphery and the space of superstructure and the building built, because vibration caused by subway circulation (horizontal direction and vertical) is relaxed to living
The adverse effect urgent need that adaptive generates is addressed.
Now, normal stack rubber support and sliding and shock isolation are the seismic isolation technologies of comparative maturity, due to its function of shock insulation master
In terms of being horizontal seismic isolation, the poor effect of vertical earthquake isolating hardly has vertical earthquake isolating function.
Notification number is that the Chinese utility model patent of CN 2905932Y discloses a kind of horizontal-vertical composite shock insulation dress
It sets, which is made of lead core rubber support vibration isolator and vertical earthquake isolating device, and vertical earthquake isolating device is by the main disk spring in center
Group, auxiliary disk spring group compose in parallel；Wherein, the main disk spring group in center is placed in centre, assists disk spring group
Center is uniformly distributed to be internally provided with main disk spring group guide cylinder with the main disk spring group in center, is equipped with inside auxiliary disk spring group
Pressing sleeve is arranged at the disk spring group top of guide cylinder, the main disk spring group in center and auxiliary disk spring group.What the device had
The ability of level of isolation and vertical seismic action simultaneously.But the support uses to improve vertical bearing capacity and vertical deformation ability
The disk spring of multiple groups parallel arrangement, and each group disk spring height is larger, being also easy to produce to wave causes to topple, weaken support
Multiple dimension shock-proof effect.Application No. is 200420083525.8 Chinese utility model patents to disclose a kind of Three-dimensional rubber shake-insulating holder
It is composed of up and down double-layer rubber shock isolating pedestal, vertical stability is undesirable.
Traditional rubber earthquake isolation support due to that need to take into account that vertical rigidity is big in design and the small both sides problem of horizontal rigidity,
So design pressure should not be too big, general control is 10 between 15Mpa, and shock insulation vertical earthquake isolating support body of the present invention only needs
Vertical rigidity problem is considered emphatically, design pressure can be designed by 24 to 30Mpa, when bearing identical load, rubber support ruler
It is very little to be greatly lowered, it can effectively solve that large-scale rubber earthquake isolation support process issues must be solved in skyscraper utilization.
Utility model content:
The purpose of this utility model is to overcome the above deficiency, it is simple to provide a kind of structure, at low cost, each member function
The division of labor is clear, and quality can be guaranteed, and replacement is convenient, the good three-dimensional shock isolation support of isolating affection.
The purpose of this utility model is achieved like this:
The utility model three-dimensional shock isolation support, including upper base plate, lower seat board, the vertical rubber between upper and lower seat board every
The limit plate in limit sleeve is protruded into shake support body, the limit sleeve positioned at vertical rubber earthquake isolation support body peripheral edge, upper end, limits
Board bottom portion is equipped with polyfluortetraethylene plate, and the position of opposite polyfluortetraethylene plate is equipped with stainless steel plate on lower seat board.
Above-mentioned vertical rubber earthquake isolation support main body is alternately formed by stacking by sheet metal and rubber layer.
The natural frequency of vibration of above-mentioned vertical rubber glue shock isolating pedestal main body is 1~12Hz.
Have between above-mentioned upper base plate, lower seat board along guide sleeve circumferential distribution and resets rubber shear spring.
There is the reset rubber shear spring on upper buttress, lower buttress on above-mentioned upper base plate, lower seat board periphery.
The utility model is composed using vertical earthquake isolating and slip level shock insulation.More above-mentioned two in vertical structure height
A utility model greatly reduces, and overcomes the undesirable problem of vertical stability.Vertical rubber earthquake isolation support main body uses lamination
Rubber support technology is alternately formed by stacking by sheet metal and rubber layer, since horizontal change does not occur for vertical rubber earthquake isolation support main body
Shape, therefore vertical rigidity significantly reduces than traditional rubber earthquake isolation support, can add between 1~12HZ by vertical Frequency Design
With design, since vertical rigidity is small, this structure of rubber layer can lengthen house natural vibration period, make it away from seismic wave characteristic week
Phase reduces earthquake and vertically acts on.Horizontal seismic isolation forms friction pair by the polyfluortetraethylene plate and stainless steel plate of pressure-bearing, and rub secondary system
Number is small to 0.01, make earthquake pass to superstructure horizontal force be only very little frictional force, the effect of horizontal seismic isolation is reached with this
Fruit.Rubber shear spring is resetted between upper and lower seat board or upper and lower buttress, can have the function that horizontal reset.It is final comprehensive
Close the purpose for realizing three-dimensional isolation.
The utility model structure is simple, at low cost, and each member function division of labor is clear, and quality can be guaranteed, and replacement is convenient,
Isolating affection is good.
