Elastic hinge bearings, contact Liu Hao Tong, seismic elastic hinge bearings provided by Hao-engineered rubber. Elastic hinge bearings, contact Liu Hao Tong, seismic elastic hinge bearings are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 has been newly upgraded launched steel pots hoop stress Checking tension of the ring of steel pots, design level of internal forces, the design level resistance, rubber sheet under pressure to produce a radial design, design vertical reaction force, the thickness of the rubber sheet design, the level of force generated design internal forces, longitudinal horizontal force generation design internal forces, ball bearing hinge lateral horizontal force Design of internal forces generated compressive strength steel standard values, partial safety factors, the recommended value, rubber board area, bottom basin ring diameter, the inner diameter of the ring bottom basin, basin bottom ball joint bearing ring height, steel pots withstand shear ring. Bottom basin rings withstand shear design value, the bottom bowl ring design value of shear strength, design radial compressive forces generated by the ball bearing hinges, rubber board level to produce shear design value, the compressive strength of standard steel ball bearing hinges value of partial safety factors recommended value 1.10, bottom basin ring diameter, bottom diameter pots yellow unidirectional sliding elastic hinge bearings, steel bottom plate pelvic tension design values ??of tensile strength steel bottom plate design value of the pelvic floor, the ball pinned Block reaction force design value, the standard value of compressive strength of steel bi-elastic hinge slide bearing, the design strength allowable value is generally taken to be 140mpa, itemized safety factor. Pelvic floor plate steel ball bearing hinge hoop area, the outer diameter of the ring of steel pots, steel plate thickness of the pelvic floor, on the roof or in the middle and bottom steel bowl ring contact checking, assuming that the width of the roof on a fast connection surface, then the provider or intermediate floor and roof the contact surface of the bottom bowl ring can be designed to average mechanical resistance ball joint bearing contact surfaces should be the fundamental role of a combination of verification. Flat contact surface checking. Flat contact force design value, the roof plane contact ball bearing hinge strength design value, the standard value of compressive strength of steel materials analysis coefficient recommended value, within the steel basin ring diameter, the height of the ceiling height in contact with the basin ring, curved contact surface the radius of curvature R ball bearing hinge situation contact force design value, on top or intermediate steel surface contact strength design value, the material partial coefficient recommended value, the value of the cylinder inner basin ring contact surface curvature radius, design elastic modulus, geometric rotation requirements conditions, the role of the basic combination, shall comply with the following requirements elastic hinge bearing on the roof or intermediate steel plate with rubber elastic precipitation should be closed edge of the contact surface is formed along the entire perimeter of the basin at the bottom of a cylindrical ring groove ball Hinge Bearing neither from the basin edge of the ring, the ring wall and the top end of basin there should not be any contact with the metal member, subject to the following conditions in order to meet the above conditions, the ball bearing hinge effective height of the bottom bowl rings, rubber sheet elastic material thickness Fixed elastic hinge bearing on the roof or in the middle of the plate and bowl ring contact height, the height of the roof or intermediate plate in contact with the basin ring surfaces, maximum design angle. Ball bearing hinge ring diameter inner bottom basin, corner plates on the top surface of the roof or intermediate diameter, the surplus amount, the elastic modulus of the material design, the design value of horizontal force, surface contact area radius, variable effects produced. Steel plate stress ball bearing hinge design or design reaction force bearing capacity, steel floor area, the steel plate side length, allowable stress of steel plate material, steel plate material strength standard value, safety factors recommendations.
