Hao-engineering rubber, GPZ pot rubber bearing manufacturers, GPZ rubber bearing basin is provided by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical bearings for steel making not cause the upper and lower bearing structural separation GPZ pot rubber bearing, spherical bearing it should be able to withstand the fight 20% of the horizontal force, the sea Britain can withstand 20% or more of the pull force. GPZ rubber bearing basin size, pulling force on the general spherical bearing test device, the test, the spherical bearing mounted to pull the shelf, and makes bearing center, tension center, supporting frame center and the center position in the test machine load the same center line, the test load of 1.2 times the pulling power of design loads, test type, the first pre-press, and then officially loaded, each load and load regulation 2min, the data recording displacement sensor, known test load regulator After uninstalling GPZ pot rubber bearing manufacturer, the loading process carried out three consecutive times, bearing vertical tensile deformation were taken four displacement sensor readings arithmetic mean of the GPZ rubber bearing basin and draw load-deformation curve, test load deformation curve on 5000KN test machine, the variable should include test equipment such as tensile deformation, including racks, bearing deformation is small, spherical bearings by mechanical testing, can be considered a carrying capacity of spherical bearings size, and can better adapt to the form of the rotation bearing performance requirements. Equipped with high-pressure tubing of different lengths and proper dispensing valve, using a pump trailer and more top ways to adapt to the construction site to meet the job requirements. Seismic horizontal forces dispersed structure due to the location of the bridge bearings, multi-constrained operating space, the use of multi-point fixed way of setting fixed bearing structures in several piers providers. When the earthquake, the inertial force of the upper structure were passed through a high fixed bearing on the seismic performance of the pier to the lower pick Oh shares, which for structural and economic characteristics are unfavorable, therefore, at this time needs to be done about the way the use of the full study . As an example of the seismic horizontal forces dispersed structure of multi-point fixation can be rubber bearings so choose waveform jack to become one of the preferred device. At present, the domestic production of such equipment manufacturing plant gathered, now commonly used lifting jacks models and their corresponding parameters are introduced briefly.
