Product description

First, the introduction of products

GPZ (2009) type highway bridge basin type rubber bearing consists of an upper base plate, bottom plate, middle pressure plate, rubber plate, copper seal, rubber seals, PTFE, SF-1B composite plate, stainless steel plate, dustproof ring and other components. According to the bearing vertical bearing capacity is divided into 0.4MN ~ 60MN 33 specifications the structure, with the common pot type rubber bearing, increase the dust ring, to avoid contamination of the lower seat board pelvic in the harsh environment. The bearing capacity of vertical bearing capacity for one-way movable 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) support increases the dust ring, avoid the support in the long-term use, the horizontal displacement, the plastic deformation occurs under the action of angular displacement, the middle plate and the pelvic space increased, environmental dust, moisture, corrosion gas will cause corrosion into the pelvic cavity on the phenomenon of bearing service life of corrosion and other effects.

4 the upper and lower seat plate exposed parts using precision casting molding, not mechanical processing, is conducive to increase the adhesion of anti-corrosion coating, to extend the anti-corrosion life, but also reduce the amount of steel and manufacturing cost, significant economic benefits;

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

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

Three, product application

GPZ (2009) type highway bridge basin type rubber bearing 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 the bridge design specifications and related requirements. Our company to optimize the design of the support structure, actively adopt high new material feeding, 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.
