Spherical cap rubber bearings circular plate [] performance and features circular plate spherical cap rubber bearings [] on the transfer force uniform, especially those with a certain aspect of the slope was significantly better than conventional flat circular rubber bearing type [], it can effectively reliably delivered to the load of the upper structure of the steel bridge substructure rubber bearings, and greatly improve the bias generated during installation waited in vain off negative phenomena, widely used, not only for general bridges, more suitable for a variety of complex layout, larger longitudinal overpass and viaduct. [] Classification rubber bearing a, ball cap round rubber bearing type [] (see diagram 1) b, Teflon ball cap round rubber bearings that ball cap round rubber bearing and bearing an underside paste same plane size of PTFE plate vulcanizing (see diagram 2) bearing model and representation example spherical cap rubber bearings Circular [] model TCYB Examples Example 1 TCYB200 × 28, said bearing diameter φ200mm, thickness ball cap round 28mm rubber bearing sample of 2 TCYB250 × 35F4, said bearing diameter φ250mm, 35mm thick Teflon ball cap round rubber bearing rubber bearing [1] temperature range, neoprene type: + 60 ℃ ~ -25 ℃ 2, NR type: + 60 ℃ ~ -40 ℃ 3, EPDM type: + 60 ℃ ~ -45 ℃] [rubber bearing rubber bearing production materials [chlorine] butadiene rubber: has excellent resistance to weathering and excellent ozone resistance (anti-aging properties of ozone than natural rubber high-more than 12 times), high tensile strength rubber bridge bearings, good flexibility, good corrosion resistance, and has a certain degree of oil resistance. Bridge is the main material of rubber bearings commonly used at home and abroad, but its poor low temperature performance, rubber bearing [] which limits its use in cold northern regions. [] EPDM rubber bearings: a polymer material with excellent resistance to aging and resistance to high and low temperature performance at -55 ℃ still flex at 100 ℃ long-term work. Moreover, its impact resistance, water absorption, acid and alkali chemical corrosion. The main drawback is the low metal bonding properties, but this disadvantage is gradually improved. Combining the three main advantages and disadvantages of rubber material rubber bearing bridge unit price, the choice of rubber bearing material, the temperature conditions should be considered the main area of ??the bridge position. From the building structure to stress member, to stress to the development of the structure, have a longer time, the stress applied to the development of components and building structures to stress the advantages of the structure, in many cities in the building, has been relatively wide range of applications. In urban construction and development, promotion and application, and I stress I stress member structure, can indeed play a positive role. However, there is a very important structural dynamics problems require special attention to the problem of so-called architectural structural dynamics, that is, when the earthquake erupted PTFE plate bridge rubber bearings, seismic shock wave forced dynamic response of structures to generate vibration, seismic shock the impact of the building structure, to produce the internal forces in the structure is passed, and the mechanical model and to stress to the stress component structure are: 1) to stress the tension on both ends fixed end into the holder, is not allowed to have any change; [ rubber bearings] Guangrun build quality.
