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 in 20 years futures even longer a period of time, 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 turn into national synthesized economic strength and modernization construction
Remarkable embodiment.Therefore, building trade will constantly increase the demand of seismic isolation device, to the technical performance of seismic isolation device
Requirement with economic performance will also be improved constantly.Domestic and international the most frequently used seismic isolation device has four kinds at present：Elastic-plastic damping is filled
Put, hydraulic damping device, pendulum model shock isolating pedestal and rubber earthquake isolation support.
Elastic-plastic damping device belongs to cushioning product, with very strong energy dissipation capacity, and products characteristics have damping ratio height, power consumption energy
Power is strong, damping effect is obvious.But it is difficult to control in vertical height.
Hydraulic damping device belongs to cushioning product, and with very strong energy dissipation capacity, hydraulic damping device adds for existing engineering
Gu easily, it is not necessary to other structures are set up, while not influenceing original structure design；Speed lockup's device can exist movable pier
Anchor block is changed into during earthquake, seismic force is shared, it is effective to carry out antidetonation using existing pier, with higher economy, but its
Production, maintenance cost are higher.
Pendulum model shock isolating pedestal, belongs to shock insulation product, can play good isolating affection, while can select as needed not
Same coefficient of friction is for different energy dissipation capacities, it is adaptable to the high any bridge in earthquake region or building, while having good economy
Property, maintenance cost is also low, while larger displacement can be provided, but such bearing is not suitable for the work that is required to corner
Occasion.
Rubber earthquake isolation support, belongs to shock insulation product, can play certain isolating affection, and rubber earthquake isolation support is equal at home and abroad
Obtained it is substantial amounts of use, formed national standard.It is not suitable for the bridge or building on weak soil ground, while the quality of product
There is close relationship with rubber performance, it is therefore necessary to strictly control rubber quality, while rubber has problem of aging.Earthquake isolating equipment
Suitable for I, II place, for weak soil III, IV class place there is certain limitation.
In summary, the defect that domestic outer support is present at present has that production, maintenance cost are higher, and bearing is in vertical height
It is difficult to control to；Not enough, bearing fails within the building life phase, has for weak soil for the anticorrosive of support material, ageing resistance
Certain limitation.
The content of the invention

Embodiment：
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, dish
Three kinds of vibration absorption units 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, installs disk spring group 1 on base 8, the inside of disk spring group 1 is equipped with
Short-range missile bar 5, double-deck 3 points of rubber sleeve is inside and outside two layers, and tubulose lead for retractable pencil 4 is embedded in double-deck rubber sleeve 3, is integrally placed in base 8
During centre is columnar structured, disk spring group 1 is placed in the double-deck internal layer of rubber sleeve 3, shock-absorbing unit 7 be placed in base 8 it is columnar structured on
Portion, 4 connection upper end covers 6 of outside fix removable pin 2 and base 8, ensure that 4 outside fix removable pins 2 insert four rubber during installation
In the hole of guide pad 9.
Shock-absorbing unit 7 is non-principal load-supporting part, and using rubber and the overlaying structure of sheet metal, shock mount is installed to bridge
Liang Hou, combines the lower surface of upper end cover 6 and shock-absorbing unit 7 by the deadweight of bridge plate in itself, prevents shock-absorbing unit 7 in shock mount
Because pressure is excessive and fails when normally using.To there is size in the internal diameter size of upper end cover 6 public with the columnar structured internal diameter size of base 8
Difference；The stem portion size of outside fix removable pin 2 and the pin-and-hole size of base 8 have that size is poor, and this structure is given on shock mount
The horizontal direction free degree of end cap 6, enables the function that shock-absorbing unit 7 absorbs oscillation crosswise to be sent out when bridge is influenceed by secondary wave
Wave.Meanwhile, in 4 pin-and-hole part recessings of base 8,4 rubber guide pads 9 are placed in groove, its hole size with it is outer fixed
Position removable pin stem portion external diameter is equal, thereby guarantees that the accuracy of assembling and the relative stability of structure.
Bottom Lve Zhai tops slightly wide truncated conical shape is designed to inside the cylindrical portions of base 8, the part is casting, has been conducive to
Mould；Lateral expansion space is given when double-deck rubber sleeve 3 is by longitudinal pressure, prevents elastomeric material at the columnar structured end of base 8
There is stress concentration in portion.
Tubulose lead for retractable pencil 4 and short-range missile bar 5 are cast using centre spinning, and tubulose lead for retractable pencil 4 should meet form and dimensional precision
It is required that；Short-range missile bar 5 need to ensure on slightly narrow lower slightly wide profile, greatest circle size must not reach disk spring inner circle basic size,
Without required precision.
Disk spring group 1 is main shock-absorption unit, and the solid disk spring of use has good rigidity.Double-deck rubber sleeve
In 3 insertion tubulose lead for retractable pencils 4, tubulose lead for retractable pencil 4 can lift the stability of elastic system, but lead material matter is soft, not interfere with shock-absorbing effect
Really.Disk spring group 1 is combined with the double-deck rubber sleeve 3 of embedded tubulose lead for retractable pencil 4, while shock mount improving stability is made,
The good shock-absorbing performance of shock mount is remained again, so that bridge is more stablized, maintenance cost reduction.
It can show that the present invention has good rigidity, stability during specific implementation and use；Can the perpendicular value of control
Highly；Adapt to various soil structures；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；With well it is economical, maintenance cost is relatively low；The material of vibration damping holder has anti-corruption
Corrosion.Therefore, this kind of shock mount can be applied in the shock mitigation systems such as building, bridge as damping device, set using damping
Meter can undoubtedly greatly improve the shock resistance of building, it is ensured that when strength earthquake occurs, and keep the use function of building, it will give
Society brings huge economic benefit and social effect.
