Hebei Hengshui first rubber bearings

1 QPZ highway bridge pot rubber bearing which uses the intermediate guide, the new structure, by good mechanical properties, which is particularly suitable for curved bridge and lateral bending of large wide bridge abutment. Our experience TPZ series based on rubber bearing basin, the research and designed a one-way movable intermediate guide trough rubber bearing products. Because TPZ, GPZ series rubber bearings are on both sides of the guide slot activity rubber bearings, when used in multi-span continuous, due sunshine beam temperature stress caused by scoliosis, and activities on both sides of the guide slot unidirectional It supports easy to produce binding, while the middle one-way bearing activities guide slot when the beam generated scoliosis, intermediate guide groove bearing intermediate steel liner plate can be driven to do a small amount of rotation. Avoid lateral binding. 2.A. two-way bearing activities: a vertical rotation and vertical and horizontal slip performance, codenamed SX. B. one-way bearing activities: a vertical slip properties of a single direction of rotation of the symbol DX. C. fixed support: there is only the amount of vertical rotation capability, code-named GD. 2, GPZ rubber bearing code GPZ XXX SX (DX, GD) (F) indicates cold type, room type does not mean: SX represents type of support: XXX can be a number of vertical bearing capacity units kn; GPZ Bearing Name: Highway 3 pot bearings, rubber bearing temperature range: A. Normal temperature type bearings: Suitable for -25 ℃ --- 60 ℃; B cold-type bearings: Suitable for -25 ℃ --- 60 ℃, code-named F 4, GPZ technical performance:. A bearing vertical angle of not less than 40 '. B. Vertical Bearing Capacity (kn) 1000 --- 50000 consists of 28, the level of non-slip surface of the bearing capacity of 10% vertical. C. friction coefficient: room type μ≤0.04, cold-type μ≤0.06 GPZ rubber bearing compression set by the state is not greater than 2% of the total height of the holder, pot ring radial deformation is not greater than the outer diameter of the pot ring 0.5 ‰ Therefore, we produced GPZ series of roads and bridges rubber bearing basin is divided into GPZ (based JT3141-90) and GPZ (Ⅱ) (based GT391-1999) and QPZ, QZ, SH-PZ, KPZ, GPZ (KZ ) several series.
