Abstract
The utility model relates to an ageing-resistant shock insulation rubber bearing for building bridges. The ageing-resistant shock insulation rubber bearing comprises an upper closing plate, a lower closing plate, a rubber bearing strength-bearing body located between the upper closing plate and the lower closing plate and connected with the upper closing plate and the lower closing plate in a composite mode, and an ethylene propylene diene monomer protection layer which is located on peripheries of the rubber bearing strength-bearing body and the upper closing plate and the lower closing plate, and connected with the rubber bearing strength-bearing body and the upper closing plate and the lower closing plate in a composite mode. According to the ageing-resistant shock insulation rubber bearing, entire ageing-resistant performance is significantly improved, ageing-resistant service life is improved, and service life the same as the building bridges can be achieved.
Description
Technical field:
The utility model relates to a kind of building a bridge and uses shock insulation rubber bearing, particularly be a kind of aging-resistant shock insulation rubber bearing.
Background technology:
At present, the domestic construction bridge mainly contains natural rubber and high-damping rubber with shock insulation rubber bearing pressure-bearing entity part rubber.The direct entity part rubber of using that its topping rubber has, what also have carries out ageing resistace allotment on the basis of natural rubber and high-damping rubber, but the not too big improvement of its ageing resistance, can not really reach and builds a bridge with the ideal state in life-span.Ordinary circumstance, elastomeric material are influenced by oxygen, ozone, ultraviolet ray etc., aging cracking can occur.Usually ageing of rubber is to be begun by the surface, causes the crack to internal extended lentamente then.Domestic shock insulation rubber bearing destroys because of reasons such as aging crackings, causes that the situation of bearing replacement often takes place, and it is often up to a million to change the expense that one or two bearing take place.
The utility model content:
The purpose of the utility model is can improve whole ageing resistace greatly in order to provide a kind of, improves anti-aging application life, can use shock insulation rubber bearing with the bridge construction that builds a bridge with the life-span.
The purpose of the utility model realizes like this:
The utility model aging-resistant shock insulation rubber bearing; Comprise upper sealing plate, following shrouding; Be positioned at neoprene bearing load entity compound between upper and lower shrouding with upper and lower shrouding; Be positioned at neoprene bearing load entity and upper and lower shrouding periphery with neoprene bearing load entity and the compound ethylene-propylene-diene monomer compound protective layer of upper and lower shrouding, the surface that makes the load entity and atmosphere and illumination isolation.
Above-mentioned neoprene bearing load entity alternately is composited by multilayer rubber layer and multilayer middle steel plate each other.
Above-mentioned neoprene bearing is provided with interstitial hole.
The utility model has increased the anti-aging and low temperature resistant topping of one deck at the periphery of upper and lower shrouding and load entity.This topping is isolated neoprene bearing load entity and atmosphere and illumination effectively.This topping adopts ethylene propylene diene rubber, and its resistance to low temperature and natural rubber are suitable, and anti-ozone aging improves about 450 times than natural rubber, improves about 60 times than neoprene.Because the thickness of topping can be merely 10 millimeter; The consumption of protective material seldom; So select for use material anti-aging, that resistance to low temperature is good especially to make the whole ageing resistace that topping can greatly improve neoprene bearing, can not increase the cost of how many shock insulation rubber bearings again.The manufacturing process of the utility model is simple, can the periphery of neoprene bearing be added the anti-aging and low temperature resistant material of one deck in the former shock insulation neoprene bearing vulcanization process stage, adorns the mould sulfidization molding then and gets final product.Also can directly, the sulfuration of shock insulation rubber bearing entity wrap up one deck ethylene propylene diene rubber after accomplishing.
The utility model can improve the ageing resistace of rubber topping, stops aging generation to diffusion inside and aging cracking, effectively prevents former thereby change the situation generation of bearing because of aging cracking etc.; Improve the whole ageing resistance ability of shock insulation rubber bearing greatly; Improve anti-aging application life greatly, really accomplish bearing and build a bridge the same life-span, manufacturing process is simple; Cost increases few, and cost performance is high.
Description of drawings:
Fig. 1 is the utility model shock insulation rubber bearing structural representation.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
Referring to Fig. 1, Fig. 2; The aging-resistant shock insulation rubber bearing of present embodiment LRB500 * 158; Comprise upper sealing plate 1, following shrouding 2; Be positioned at neoprene bearing load entity 3 compound between upper and lower shrouding with upper and lower shrouding, be positioned at neoprene bearing load entity and upper and lower shrouding the periphery with neoprene bearing load entity and the compound ethylene-propylene-diene monomer compound protective layer 4 of upper and lower shrouding.Neoprene bearing load entity is formed by 15 layers of rubber layer 5 and 14 layers of middle steel plate 6 mutual alternate combinations.Neoprene bearing is provided with interstitial hole 7.
Upper and lower shrouding uses Φ 500 * 20 steel plates to process respectively, and rubber layer 5 adopts the natural rubber sheet that is of a size of Φ 500 * 5.Middle steel plate 6 uses common low charcoal plate size to be Φ 500 * 2.5.The ethylene-propylene-diene monomer compound protective layer, thick 10mm evenly is wrapped in neoprene bearing load entity and upper and lower shrouding periphery and forms anti-aging, low temperature resistant shock insulation rubber bearing.The die casting lead for retractable pencil has been the lead for retractable pencil shock insulation rubber bearing in interstitial hole, and not die casting lead for retractable pencil is no lead for retractable pencil shock insulation rubber bearing.
Claims (3)
1. aging-resistant shock insulation rubber bearing; It is characterized in that comprising upper sealing plate, following shrouding; Be positioned at neoprene bearing load entity compound between upper and lower shrouding with upper and lower shrouding, be positioned at neoprene bearing load entity and upper and lower shrouding the periphery with neoprene bearing load entity and the compound ethylene-propylene-diene monomer compound protective layer of upper and lower shrouding.
2. aging-resistant shock insulation rubber bearing as claimed in claim 1 is characterized in that neoprene bearing load entity alternately is composited by multilayer rubber layer and multilayer middle steel plate each other.
