Abstract
The utility model belongs to the technical field of earthquake-proof construction, and relates to a lead-coated shock absorbing rubber support, which comprises a shock absorbing support body and a lead, wherein a lead hole is disposed in the center of the shock absorbing support body, and the lead is mounted inside the lead hole. The lead-coated shock absorbing rubber support is characterized in that an elastic barrel is tightly wrapped around the lead and the outer wall of the elastic barrel contacts with the inner wall of the lead hole tightly. The lead-coated shock absorbing rubber support has simple and reasonable structure, prevents the lead from contacting with a steel board directly by wrapping the elastic barrel around the lead, leads initial rigidity of the support to become small, greatly improves shock absorbing property, and achieves convenient production without increasing cost by a wide margin.
Description
Technical field
The utility model belongs to the building aseismicity technical field, relates to the earthquake isolating equipment that a kind of building or building structure use, and specifically is a kind of lead core cladding vibration isolating rubber bearing.
Background technology
Answer the reduction of fluctuating acceleration when the most basic feature of shock-insulating building is earthquake, answer fluctuating acceleration low more, just more little to the destruction that building causes.Rubber earthquake isolation support just possesses these three isolation component necessary function of support, restorability and energy dissipating performance, and is widely used in the shock insulation assembly of building or building structure (as bridge, highway).The tradition rubber earthquake isolation support is to replace bonding overlapping parts by rubber plate and steel plate, and it is very hard that it has vertical direction, very soft and the feature that can smooth-going distortion of horizontal direction.
For optimizing the performance of traditional rubber earthquake isolation support, designed a kind of structure of partly having inserted lead for retractable pencil at the rubber earthquake isolation support center, i.e. the lead-rubber shock isolating pedestal.Find through observation, shock-insulating building under the situation of having used the lead-rubber shock isolating pedestal, in very rare earthquake magnitude is 6～7 grades violent earthquake, the shock-insulation building deposits yields 300cm/s
2～400cm/s
2Acceleration.As seen, the initial stage rigidity when the lead-rubber shock isolating pedestal of this structure exists in the horizontal direction distortion is too high, causes the characteristic that promotes vibration severity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, and isolation property improves greatly, lead core cladding vibration isolating rubber bearing convenient for production and cheap for manufacturing cost.
The technical scheme that provides according to the utility model, described lead core cladding vibration isolating rubber bearing comprises vibration isolating suspension body and lead for retractable pencil, vibration isolating suspension body center offers the lead for retractable pencil hole, lead for retractable pencil is contained in the lead for retractable pencil hole, it is characterized in that, closely be coated with the elasticity tube around the described lead for retractable pencil, the elasticity drum outer wall closely contacts with lead for retractable pencil hole inwall.
As further improvement of the utility model, described vibration isolating suspension body comprises rubber plate and steel plate, and rubber plate and steel plate be alternately overlapping, be adhesively fixed; The lead for retractable pencil hole is offered at the center of rubber plate and steel plate.
As further improvement of the utility model, described elasticity tube is at least one, and a plurality of elasticity tubes vertically laminate, and are coated on the lead for retractable pencil.
As further improvement of the utility model, the barrel thickness of described elasticity tube is more than the 1mm.
As further improvement of the utility model, described elasticity tube adopts material such as rubber with elastic deformation and restoration characteristics to be made.
As further improvement of the utility model, described lead for retractable pencil adopts the material such as the Zn-Al alloy that have superplasticity character at normal temperatures to be made.
The utility model compared with prior art, advantage is: simple and reasonable, by coating the elasticity tube around the lead for retractable pencil, make lead for retractable pencil directly not contact steel plate, the initial stiffness of bearing diminishes, and isolation property improves greatly, and is convenient for production and can not increase considerably cost.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is that A-A among Fig. 1 is to sectional view.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model mainly is made up of vibration isolating suspension body 1, lead for retractable pencil 4 and elasticity tube 5, vibration isolating suspension body 1 is alternately overlapping by rubber plate 2 and steel plate 3, being adhesively fixed forms, the center of rubber plate 2 and steel plate 3 offers the lead for retractable pencil hole, lead for retractable pencil 4 is contained in the lead for retractable pencil hole, closely be coated with elasticity tube 5 around the lead for retractable pencil 4, elasticity tube 5 outer walls closely contact with lead for retractable pencil hole inwall.Described elasticity tube 5 can be finished with vibration isolating suspension body 1 when vibration isolating suspension body 1 is made, and also can be pressed into after 1 manufacturing of vibration isolating suspension body is finished again.Described lead for retractable pencil 4 can pre-set when vibration isolating suspension body 1 sulfuration press forming, also can be pressed into after 1 manufacturing of vibration isolating suspension body is finished again.Which kind of, all to keep closely contacting between the lead for retractable pencil hole inwall of elasticity tube 5 and lead for retractable pencil 4, vibration isolating suspension body 1 no matter adopt mode.
Described elasticity tube 5 can be an integral body, also can be the aggregate of a plurality of elasticity tubes 5, and a plurality of elasticity tubes 5 vertically laminate, and are coated on the lead for retractable pencil 4.The barrel thickness of described elasticity tube 5 should be more than the 1mm, by adjusting the barrel thickness of elasticity tube 5, can adjust initial shear rigidity of the present utility model.
Described elasticity tube 5 adopts has the material of elastic deformation and restoration characteristics, manufacturing materials can adopt macromolecule chemical material such as rubber, also can adopt metal, as long as the elasticity tube of making 5 still has the characteristic of elastic deformation and recovery after coating lead for retractable pencil 4.
Material such as Zn-Al alloy that described lead for retractable pencil 4 preferred employings have superplasticity character at normal temperatures are made.
