horizontal force dispersed rubber bearings
First, product introduction
The horizontal force dispersed rubber bearing by upper and lower connecting plate, high performance rubber, reinforced steel plate, especially in the upper and lower connecting plate, composite high performance rubber, vulcanized reinforced steel plate composite structure, its structure and general rubber plate bearing. Connecting plate and beam and pier for connection.
Two, bearing characteristics
1) the use of composite high performance rubber materials, with the carrying capacity, restoring force and damping (absorption of energy) Trinity function;
2) horizontal force dispersed rubber bearings have superior hysteretic characteristics, to the wind and large, medium and small earthquakes can play the role of isolation;
3) horizontal force dispersed rubber bearing to play the function of isolation, no need to configure other devices, so the maintenance cost is low;
4) horizontal force dispersed rubber bearing in large earthquake, will not produce residual stress, and the characteristics of the change is very small, no need to replace;
5) the elastic properties and damping characteristics of the horizontal force dispersed rubber bearing are very small to the environmental temperature, and can be applied to the wide area;
Three, bearing application
The horizontal force dispersed rubber rubber bearing the strict implementation of national standard JT/T20688-2006< People's Republic of China traffic bridge seismic isolation rubber bearing "and relevant industry standards, with reference to the isolation bridge component products of reduction of bridge support requirements and development of European standard EN15129-2009< isolation device >, further optimization of the design parameters and structure, comprehensive performance of the product obtained the further improved. Applicable to 7 degree earthquake intensity area of highway and municipal bridge.
Our company has the first joint design institute, technology transfer LNR (170~620) fixed type, horizontal dispersion force of sliding rubber bearing.
Related to the horizontal force dispersed rubber bearing has been successfully applied in Lanzhou and other domestic large and medium-sized city bridge engineering.
