wind resistant pot-type rubber bearings

First, the introduction of products

Wind pot rubber bearing consists of an upper base plate, a bottom plate, the middle plate, rubber bearing plate, copper seal, rubber seals, PTFE plate, stainless steel plate, disc spring, adjusting plate, ring, transition plate and other components. The structure and common pot type rubber bearing, increase the disc spring, the adjustment plate, the transition plate makes the bearing ring, adjustable height, good damping performance of anti-seismic.

Two, product features

1 the pressure rubber plate in the bottom of the basin is in a three phase constraint state, the energy absorption of the rubber, the energy dissipation function is fully played, and has the advantages of large bearing capacity, shock absorption, and obvious isolation effect;

2) the rotation angle of the support vertical curve is 0.02rad, and at the same time, the rotation of the horizontal curve is flexible;

3) disc spring, adjusting plate, ring, transition plate structure, which has good seismic, seismic performance;

4) bearing friction coefficient is less than 0.03, with the use of lubricating grease, which greatly improves the bearing life;

(5) ambient temperature range of application (-40 C ~ +60 C), can be widely used in the region;

6) the large displacement characteristics of the bearings, can meet the cross river, cross the canyon and other special large displacement bridge engineering;

7) this type of support is usually used in combination with the vertical tension and compression support, which can effectively reduce the impact of the lateral wind shock on the bridge.

Three, product application

Wind type basin type rubber bearing a series of strict implementation of the provisions of the People's Republic of China traffic industry standard JT/T 391-2009< highway bridge basin type rubber bearing on seismic isolation and reduction structure and related requirements. In recent years, in order to meet the constraints of bridge engineering, environmental factors of large span, gradually increasing the application of large displacement of the bearings, the majority of this kind of bridge to cross the river, cross the canyon therefore, cross sea construction, bridge bearing must have the shock absorption, isolation, tensile, anti wind, marine corrosion and other special features.

Our company through independent R & D and production of KFPZ (300040005000KN) wind type pot rubber bearing, and successfully applied to the Balinghe bridge, Aizhai bridge, Guizhou Qingshui River bridge, the domestic large and medium-sized cross the river, cross the canyon, bridge across the sea.
