GPZ (Ⅱ) pot-type rubber bearings
First, the introduction of products
GPZ (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 and other components. According to the bearing vertical bearing capacity is divided into 0.8MN to 60MN a total of 31 specifications, one-way movable bearing for the vertical bearing capacity of bearing and fixed bearing level 10%.
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) the one-way movable bearing guide limit structure and the lower seat plate, the structure size is greatly reduced, the structure is simple, compact, easy to maintain and replace, and the economic benefit is remarkable.
4) movable 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
GPZ (II) type basin type rubber bearing a series of provisions to strictly enforce the People's Republic of China traffic industry standard JT/T 391-2009< highway bridge basin type rubber bearing on. 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 product structure, improve product performance and life. With the rapid development of Luqiao industry, has been widely used in the series of supporting domestic large and medium-sized bridge engineering.
