First, the introduction of products
Cable isolation pot rubber bearing consists of an upper base plate, a bottom plate, the middle plate, rubber bearing plate, copper seal, rubber seals, PTFE polythene sheet, SF-1B composite plate, stainless steel plate, high strength steel cables and other components. The structure is characterized by high strength steel (steel, high strength steel wire bundle) the upper and lower seat board restrictions in the effective range of the bearing displacement.
Two, product features
1), cable isolation rubber bearing inherits the advantages of pot rubber bearing the bottom bearing rubber plate in the basin in the three-phase constrained state, energy absorbing rubber consumption, full play the role of bearing capacity advantages, shock absorption, isolation effect;
2) Using the tensile characteristics of high-strength steel cable, the cable vibration reduction and isolation basin rubber bearing overcomes the weakness of weak limit capacity of the traditional bearing, can avoid the occurrence of beam falling in the earthquake, and can be reset reliably after the earthquake;
3) due to the traditional pot rubber bearing and high strength steel is widely used in bridge engineering, its manufacturing technology is mature, all the relatively similar products, low cost.
4) earthquake condition, high strength steel rope larger relative displacement on the base plate, can effectively play the role of buffer limit effect; in the earthquake, on the lower base plate in the limit displacement, radial plastic deformation of high strength steel, consumes the earthquake energy, effectively reduce the seismic response of structures and play a damping effect.
5) the rubber bearing of the cable isolation basin has made full use of the seismic advantages of the basin type bearing and the limit cable, and effectively overcome the disadvantages and shortcomings of the use of each other.
Three, product application
Cable provision pot rubber bearing isolation series of strict implementation of People's Republic of China transportation industry standard JT/T 391-2009< highway bridge basin type rubber bearing on seismic isolation and reduction structure and related requirements. Our company independently developed by LSPZ (4000~20000KN) series of cable vibration reduction pot rubber bearing, and successfully applied to the Dadu River project.
