First, the introduction of products

GKPZ (II) type of pot type rubber bearing consists of an upper base plate, a bottom plate, the middle plate, rubber bearing plate, copper seal, rubber seals, PTFE, SF-1B composite plate, stainless steel plate, damping rubber ring, bearing damping plate and other components. According to the vertical bearing capacity of 0.8MN is divided into a total of 31 ~ 60MN a specification of the structure and the common pot type rubber bearing, increase the damping rubber ring and damping plate, good damping performance. Seismic bearing capacity of vertical bearing capacity of one-way movable and fixed bearing level 20%.

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) one-way movable and fixed bearing, increasing the damping rubber ring and damping plate, good earthquake resistance, damping performance, greatly reduces the size of the structure, simple structure, compact structure, convenient maintenance and replacement, the economic benefit is remarkable.

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.

Three, product application

GKPZ (II) type of pot type rubber bearing 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. Our company conducted a number of optimization design of the support structure, actively adopt new materials, side sliding material uses SF-1B composite plate, simplifies the structure of the product, greatly enhance the product performance and service life. With the rapid development of Luqiao industry, has been widely used in the series of supporting domestic large and medium-sized bridge engineering.
