Description
Technical field
The present invention relates to a kind of Combined-type shock-absorption bearing, it is a kind of skyscraper, bridge, tunnel, subway, high ferro, city
Wide variety of important load and building blocks of function in the engineerings such as border overhead road of city.
Background technology
In following 20 years a period of times the most longer, the infrastructure construction such as China's urban public transport continues to keep
The trend of high speed development, urban viaduct, inter-city passenger rail, high-speed railway will become country's synthesized economic strength and modernization construction
Remarkable embodiment.Therefore, the demand of seismic isolation device will constantly be increased by building trade, the technical performance to seismic isolation device
Requirement with economic performance also will improve constantly.The most the most frequently used seismic isolation device has four kinds: elastic-plastic damping fills
Put, hydraulic damping device, pendulum model shock isolating pedestal and rubber earthquake isolation support.
Elastic-plastic damping device belongs to cushioning product, has the strongest energy dissipation capacity, and products characteristics has damping ratio height, power consumption energy
Power is strong, damping effect is obvious.But it is difficult to control on vertical height.
Hydraulic damping device belongs to cushioning product, has the strongest energy dissipation capacity, and hydraulic damping device adds for existing engineering
Gu easily, it is not necessary to set up other structure, do not affect the design of original structure simultaneously；Movable pier can be existed by speed lockup's device
Change into anchor block during earthquake, share seismic force, effective utilize existing pier to carry out antidetonation, there is higher economy, but its
Produce, maintenance cost higher.
Pendulum model shock isolating pedestal, belongs to shock insulation product, can play good isolating affection, can select not as required simultaneously
Same coefficient of friction is for different energy dissipation capacities, it is adaptable to any bridge in high earthquake region or building, has good economy simultaneously
Property, maintenance cost is the lowest, can provide bigger displacement simultaneously, but such bearing is not suitable for the work that requires corner
Occasion.
Rubber earthquake isolation support, belongs to shock insulation product, can play certain isolating affection, and rubber earthquake isolation support is the most equal
Obtain substantial amounts of use, form national standard.Its bridge not being suitable for weak soil ground or building, the quality of product simultaneously
Close relationship is had, it is therefore necessary to strictly controlling rubber quality, rubber exists problem of aging simultaneously with rubber performance.Earthquake isolating equipment
It is applicable to I, II place, for III, IV class place, weak soil ground, there is certain limitation.
In sum, the defect that bearing exists the most both at home and abroad has production, maintenance cost higher, and bearing is on vertical height
It is difficult to control to；Anticorrosive, the ageing resistance of support material is inadequate, and bearing lost efficacy within the building life phase, had for weak soil
Certain limitation.
Summary of the invention

Detailed description of the invention:
The present invention is a kind of lead for retractable pencil-rubber-butterfly spring group Combined-type shock-absorption bearing, and it uses lead for retractable pencil, rubber, butterfly
Three kinds of vibration absorption unit of shape groups of springs are to reach comprehensive shock-absorbing effect.
The structure of the present invention as shown in Figure 2 and Figure 3, base 8 is installed disk spring group 1, equipped with short-range missile inside groups of springs 1
Bar 5, rubber sleeve 3 is divided into inside and outside two-layer, tubulose lead for retractable pencil 4 to embed in two-layer rubber sleeve 3, is integrally placed at the central authorities of amortisseur base 8
In columnar structured, disk spring group 1 is placed in rubber sleeve 3 internal layer, and shock insulation unit 7 is placed in base 8 cylindrical structure top, outside 4
Location removable pin 2 connects upper end cover 6 and base 8, ensures that 4 outside fix removable pins 2 insert four rubber guide pad 9 holes during installation
In.
Shock insulation unit 7 is non-principal load-supporting part, uses rubber and steel-sheet overlaying structure, and amortisseur is installed to bridge
After, made upper end cover 6 lower surface and shock insulation unit 7 combine by the deadweight of bridge plate itself, prevent shock insulation unit 7 normal at amortisseur
Lost efficacy because pressure is excessive during use.There is dimensional tolerance in upper end cover 6 internal diameter size and base 8 cylindrical structure internal diameter size；Outward
There is difference in size with base 8 pin-and-hole size in location removable pin 2 stem portion size, this structure gives amortisseur upper end cover 6 water
Square to degree of freedom, the function making shock insulation unit 7 absorb oscillation crosswise is played when bridge affects by secondary wave.With
Time, in 4 pin-and-hole part recessings of base 8,4 rubber guide pads 9 are placed in groove, its hole size and outside fix activity
Pin stem portion external diameter is equal, thereby guarantees that the accuracy of assembling and the relative stability of structure.
Being designed to the truncated conical shape that Lve Zhai top, bottom is the widest inside base 8 cylindrical portions, this part is casting, is conducive to
Mould；Give lateral expansion space when rubber sleeve 3 is by longitudinal pressure, prevent elastomeric material from occurring in base 8 cylindrical structure end
Stress is concentrated.
Lead for retractable pencil 4 and short-range missile bar 5 all use centre spinning to cast, and lead for retractable pencil should meet form and dimensional precision requirement；Short-range missile
Bar 5 need to ensure on the narrowest the widest lower profile, greatest circle size must not reach disk spring inner circle basic size, without precision want
Ask.
Disk spring group 1 is main shock-absorption unit, and the solid disk spring of employing has good rigidity.Rubber sleeve 6 is embedding
Entering in lead for retractable pencil 4, lead for retractable pencil 4 can promote the stability of elastic system, but lead material matter is soft, does not interferes with shock-absorbing effect.Disk spring
Group 1 is combined with the rubber sleeve 6 embedding lead for retractable pencil 1, while making amortisseur improving stability, remains again the suction that amortisseur is good
Shock stability, so that bridge is more stable, maintenance cost reduces.
Can show that during being embodied as and using the present invention has good rigidity, stability；Perpendicular value can be controlled
Highly；Adapt to various soil structure；Enough effective displacements can be reserved to meet the deformation requirements under rarely occurred earthquake；Knot
Structure is simple, is not required to repair, easy maintenance；Having the most economical, maintenance cost is relatively low；The material subtracting vibration isolating suspension has anti-
Corrosivity.Therefore, this kind of shock mount bearing can be applied to as damping device in the shock mitigation systems such as building, bridge, uses
Aseismatic Design can be greatly improved the shock resistance of building undoubtedly, it is ensured that when strength earthquake occurs, and keeps the use function of building,
Huge economic benefit and social effect will be brought to society.
