Hao-engineering rubber, JQGZ elastic damping hinge ball bearings, ball joints bearing elastic damping 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 intermediate plate : intermediate plate located between rubber sheets and PTFE plate, the middle plate protruding below and embed the groove bottom basin, with a diameter slightly smaller than the diameter of the tank in order to ensure the flexibility of rotation, leaving the top surface of the intermediate plate forward four slot plate fluoride, PTFE plates and stainless steel plates, when the displacement of the movable carriage to meet the needs of the bridge by a relative sliding PTFE plate and stainless steel plate between them so that the absorption of green tea requirement as small as possible. PTFE sheet thickness is 4-8mm, part thickness (generally not less than 2.5mm) embedded in the middle of the top surface of steel reserve tank, and the rest should be higher than the middle of the top surface of steel ball around 1.5-3mm hinged elastic damping seat, in order to ensure free sliding ring of stainless steel plates, the use of elastic damping ring seals JLGZ ball bearing hinges can also be used POM, filled PTFE and stainless steel ring, but it is basically in the sealing rubber sheet-like body, rubber plate helps prevent aging and being squeezed, roof, roof basin children usually do after steel, welded above is equal to or greater than 2mm thick stainless steel plate ah, its thickness depends on local bearing strength of the supporting material. The thickness of the flatness of the top plate is of stainless steel has a direct impact on the guarantee. As the roof fixed bearing can be processed from the middle of the whole plate, but also the intermediate plate after plate and can be processed separately welded together. Rise to the top position, lifting the money should the bridge construction sites, temporary closure or make good-control mode of production and sales in order to avoid the construction process conducted before jacking the bridge construction sites should temporarily be closed or traffic control GJQZ elastic damping ball bearing hinges to prevent construction accidents occur during construction, the same command to start lifting, jacking empty refers to the speed record of the subject, adjust uneven bias, know all rose to the top position, bearing smooth group at Location JQGZ elastic damping hinge ball bearing, the whole process of the barracks on the amount of lifting, deck and ancillary facilities were carefully checked know immediately stop the normal operation of the separation method jacking structural separation type functions, mainly for the vertical direction and support functions horizontal load bearing function, each of the functions necessary separation. Usually based on seismic and wind loads state level, you can have a variety of separate functional separation method.
