Rectangular (circular) plate type rubber bearing
(a) performance: This product is made of rubber sheet and multilayer thin steel inlaid, bonded by pressure, temperature and time of vulcanization repression. There is enough vertical stiffness to bearing vertical load, the upper structure of the beam plate can be reliably anti force transfer to the pier, with good elasticity. In order to adapt to the rotation of the beam end; and to meet the horizontal displacement of upper beam structure of large shear deformation.
The characteristics of the products in the bridge construction, hydropower engineering, seismic facilities housing has been widely used, compared with the original steel bearing, has simple structure, convenient installation; steel saving, low price; easy maintenance, easy replacement and other advantages, and the low building height, the bridge design and reduce the cost of benefits; there are isolated effect, can reduce the live load and seismic load impact on the building.

Laminated rubber bearing:
Laminated rubber bearing is composed of multilayer natural rubber and steel sheet inlaid, adhesive, and bearing a vulcanized rubber bearing. The bridge types have enough vertical stiffness to withstand the vertical load, and the upper structure of the pressure can be reliably transferred to the pier; have good flexibility to adapt to the rotation of the beam end have to meet; the horizontal displacement of the upper structure of the large shear deformation plate bearing according to the shape classification:
Rectangular plate, circular, spherical circular plate, circular slope shape, etc. several products.

Product code representation method
The technical performance of QZ series spherical bearing 1, bearing force (vertical bearing capacity) is divided into 16 levels; 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 7000, 8000, 9000 and 10000, 12500, 1500017500, 20000KN.
2, support design angle is divided into 0.01, 0.15 and 0.02rad (according to the need of increasing).
3, displacement of support design
Bridge to: 1000 a e 2500KN = 50 and disabilities 100mm;
3000 a e 10000KN = 50, soil 1 00mm and 1 50mm;
Transverse bridge to (GX multi direction active bearing) e = soil 2Omm
The design displacement can be changed according to the engineering requirements.
4, the coefficient of friction in the bearing design of PTFE / vinyl plate grease lubrication condition, the stress are about 30Mpa, value: room temperature (-25 C ~ + 60 C) 0.03 low temperature (-40 DEG C ~ + 40 C) 0.05
5, the bearing capacity of the bearing:
The horizontal force of the longitudinal movable bearing (ZX) is 10% of the bearing reaction force.
The fixed bearing (GD) bearing the horizontal force is 10% of the supporting force.
