Tension and compression steel ball bearings, bearing the quality of leading companies, steel ball bearing steel tension and compression provided by Hao-engineered rubber. Tension and compression steel ball bearings, bearing the quality of leading companies, steel tension and compression steel ball bearings are ball bearings in the choice of Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 has been newly upgraded launched, It should also be noted that as long as the beam end bearing deformation turn to meet the requirements, the more favorable the thinner bearing thickness, tension and compression damping steel ball again when the overall design of the bridge structure to withstand the horizontal forces due to bearing bearing shear deformation does not depend on the completion of the bearing, but also give full consideration to the fixed ball bearing, bearing activities and forms part of the curved bridge abutment structure and reasonable layout. In our country has always been a bridge and culvert specifications and industry standards, design and construction of ball bearings and acceptance requirements must be made in both the beam end bearing, bearing steel ball bearing tension and compression, snug contact with the pier and down, so that the ball type bearing force uniform, with no void phenomenon, rubber bearings in the best seismic tension and compression force uniform steel ball bearings, with no void phenomenon, to ensure the ball bearings in the best stress state, when the beam with longitudinal When the slope should be leveling processing. Currently, the world bridge normative standards such as the US AASHTO-LRFD Highway Bridge Design Code (2004) EN1337-3 European standards (2005) and others require, when the average temperature at constant loads and sliding all the tension and compression steel ball bearings, When the beam bottom is greater than the relative level of advice 0.01rad, ball bearing steel must be used to make bridges corner wedge zero level to ensure the bearing seat by force, so our bridge design specifications and bearing industry standards are clearly defined when the beam bottom longitudinal treatment must be leveling slope greater than 1%, while when the two longitudinal less than 1%, when selecting the ball bearing deformation regulations will take into account, this can not be ignored. Ball bearings are inserted regardless of type or sliding fixed (APF) (APM) 1m long polystyrene foam tape, which is easy to lay, fixed bearing (APF) with a contact point into 5mm thick elastomer, If you need to achieve a fixed structure phones, ball bearings and absorb the corner. Rubber bearing slide by the composition of the inert synthetic material and the elastomer is not stiffened vulcanized together. This high quality composite body may be to improve its performance in the friction between the plate and PTFE plus natural lubricant and polyethylene containing thin sliding sheet. Fixed and sliding contact bearings penalty-type construction and technical indicators, each bearing the APF and APM 1m long range layout, ribbon bearing size, character and layout can be changed according to the needs of the project. Rubber bearing friction coefficient of 0.05-0.10, wide sliding board is mainly used for the separation of the building and its foundation, when the playing surface of the slide bearing composed by two skateboards, skateboard posted below polystyrene foam ball The above bearing affixed 2.5mm thick fabrics can be used polystyrene 4mm, 5mm, 6mm, 8mm elastic material after. Branch rubber bearing protective layer material according to the mounting bracket and then note when pouring the concrete conditions of work choices, ball bearing slide based on the degree of risk of failure to choose. Meanwhile, the playing surface of the rubber bearings are generally 1m wide and 15m long roller transport.
