Hao-engineering rubber, universal ball joints seismic bearings, ball joints seismic bearings 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 steel bearing basin rubber bearings, spherical PTFE bearings can be considered a special case, when asked to stand only rotate in one direction, then the spherical ball bearings made of steel liner plates on both sides of the cylindrical surface seismic steal ball joint bearing, lower bearing plate slot changes accordingly, issue pot rubber bearing design considerations of basic and spherical bearing the same when subjected to horizontal loads can not meet the requirements of the following formula, be sure to provide a good external restraint system. Cylindrical surface with a coefficient of horizontal loads perimeter, under the super-strength state design corner, rubber bearing basin in accordance with the principles of design, our standard ah "ball bearing technology" for pot rubber bearing bearing specifications proposed series requirements, rubber bearing basin is divided into 21 vertical bearing capacity, that 1500kn-3000KN, bi-bearing activities along the bridge. Displacement of the displacement of the bridge rubber bearing basin to be divided into five, corner rubber bearing basin is divided into three, namely 0.02rad, 0.04rad and 0.06rad, standard spherical bearings bridges think the main specifications factor requirements, according to withstand vertical load size into 30, the displacement of two-way movable bearing and single bearing activities along the bridge to shift into transverse displacement of six seismic activity ball joint bearing, rubber bearing basin is 40mm, one-way bearing activities transverse displacement of 3mm and the amount of displacement can be adjusted according to actual needs, corner rubber bearing basin is divided into 5, 0.02rad, 0.03rad, 0.04rad, 0.05rad and 0.06rad , is now supporting the design drawings have been completed seismic universal ball joint mount for manufacturers and processing use. Rubber bearing basin elastic support structure, as a structure to withstand seismic horizontal force, generally have the following types, after a dry mix of cement and aggregate, should immediately add water and stir seismic slip the ball joint bearing, dry plate and the substance is prohibited After a period of time to prevent the addition of water, gray barracks strict control over who, after casting solidification, sentences should be effective conservation, seismic horizontal forces dispersed rubber bearing basin, is the use of pot rubber bearing shear deformation of the upper inertial force structure dispersed into the structure, damping structure is applied multiple substructure constructed with isolation function using rubber bearing basin at the other, over a long period of questions about the horizontal displacement increases earthquakes , especially bridge and foundation problems resonate in the soft ground, it must be fully aware of this when using. When the rubber bearing basin at the supports, generally adopt or rubber bearing basin rubber bearing, namely isolation and damping integral rubber bearing basin shown to be used in multi-span continuous structure constructed not with any of the other varieties of cement construction, cement easy Fenghua, must be properly stored, shelf life should not be more than three months, Fenghua cement its performance must be re-tested, qualified before use.
