Abstract

The utility model relates to an ultra-high damping rubber support which comprises an outer connecting steel plate, a support connecting steel plate and a rubber support core body, wherein the upper end surface of the rubber support core body is connected with the outer connecting steel plate through an upper sealing plate, the lower end surface of the rubber support core body is connected with the support connecting steel plate through a lower sealing plate, the rubber support core body is composed of ultra-high damping rubber and a stiffened steel plate, the lower sealing plate is connected with the support connecting steel plate into a whole to form an integrated support connecting steel plate, and the connecting surface for the integrated support connecting steel plate and the rubber support core body is a prominent dummy club I; and the upper sealing plate is connected with the outer connecting steel plate into a whole to form an integrated outer connecting steel plate, and the connecting surface for the integrated outer connecting steel plate and the rubber support core body is a prominent dummy club II. In the utility model, the ultra-high damping rubber support has high damping ratio, so that the good shock insulation effect can be achieved without a lead core added; the ultra-high damping rubber support has a simple structure, is environmental friendly and is more convenient to manufacture, assemble and install; and the phenomenon of edge burning does not easily occur during the sulfurization production process, and the rubber is more firmly stuck to the steel plate.

Description

A kind of superelevation damping rubber bearing

Technical field

The utility model relates to a kind of bridge supporting arrangement, particularly a kind of superelevation damping rubber bearing.

Background technology

[0002] present, the laminated rubber bearing in usefulness mainly contains the board-like bearing of General Purpose Rubber, lead core rubber support and common high-damping rubber bearing at home:

The board-like bearing upper and lower surfaces of General Purpose Rubber is a rubber, and is not connected at the bottom of the fine strain of millet, and bearing is prone to skidding; Influence bridge structure safe, when earthquake takes place, because bearing and bridge do not connect into together; Situation such as occur the bearing slippage easily, come off; Can not play function of shock insulation, common laminated rubber bearing damping ratio generally has only about 5% the shock insulation ability in addition;

Lead core rubber support has solved the deficiency that common laminated rubber bearing exists; Make the damping ratio of bearing >=more than 15% through in bearing, adding lead for retractable pencil; But owing to will add heavy metal lead, do not meet current environmental protection trend, therefore the bearing process has also increased more operation;

Common high-damping rubber bearing has solved the deficiency of common laminated rubber bearing and lead core rubber support existence simultaneously, and its damping ratio is between 12%～15%, but hysteresis loop is not very full, and energy dissipation capacity is relatively poor, so its isolating affection still is undesirable.Also there is following weak point in this type of bearing in addition: the following shrouding that 1, connects the neoprene bearing core body is connected steel plate with bearing be two separated components, needs to connect through bolt again, cause the seat structure complicacy, makes troubles to production, assembling and installation; 2, bearing connection steel plate is a flat configuration, occurs burning limit, rubber and steel plate easily in the production sulfidation and bonds not firm.

Summary of the invention

The technical problem that the utility model will solve is: a kind of simple in structure, safe and reliable and economical and practical a kind of superelevation damping rubber bearing is provided, and not enough to overcome above-mentioned existing in prior technology.

For solving above-mentioned technical problem; The technical scheme that the utility model is taked is: a kind of superelevation damping rubber bearing; Comprise outer steel plate, bearing connection steel plate and the neoprene bearing core body of connecting; The upper surface of neoprene bearing core body connects with the outer steel plate that is connected through upper sealing plate; Shrouding was connected the steel plate connection under the lower surface of neoprene bearing core body was passed through with bearing, and said neoprene bearing core body is made up of the superelevation damping rubber and the steel plate of putting more energy into, and said shrouding down is connected steel plate and is linked to be the integrated bearing connection of integral body formation steel plate with bearing.

Its further technical scheme is: the joint face that said integrated bearing connects steel plate and neoprene bearing core body is the convex I that exceeds;

Said upper sealing plate is linked to be the integrated outer steel plate that connects of a whole formation with the outer steel plate that is connected;

The said integrated outer joint face that connects steel plate and neoprene bearing core body is the convex II that exceeds.

Compared with prior art, a kind of superelevation damping rubber bearing of the utility model has following beneficial effect:

1, because the neoprene bearing core body that a kind of superelevation damping rubber bearing of the utility model adopts the superelevation damping rubber and the steel plate of putting more energy into to constitute; The damping ratio of bearing >=18%; Need not to add lead for retractable pencil in the bearing; Just can reach good function of shock insulation,, process also simpler because it need not leading therefore than the more environmental protection of lead for retractable pencil shock insulation rubber bearing; The following shrouding of bearing is connected steel plate and is linked to be the integrated bearing connection of whole formation steel plate with bearing; Upper sealing plate is linked to be the integrated outer steel plate that connects of a whole formation with the outer steel plate that is connected; Thereby reduced connecting bolt, and make the structure of bearing simpler, assemble and install more convenient.

2, because the joint face that its integrated bearing of a kind of superelevation damping rubber bearing of the utility model connects steel plate and neoprene bearing core body is the convex that exceeds; The integrated outer joint face that connects steel plate and neoprene bearing core body is the convex that exceeds, the production sulfidation be not easy to occur burning limit, rubber and steel plate bond more firm.

Below in conjunction with accompanying drawing and embodiment the technical characterictic of a kind of superelevation damping rubber bearing of the utility model is further described.
