Finished grid bearing manufacturers, KQGZ seismic grid movable spherical steel bearings, spherical steel 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 in order to ensure The basic function of bearing, the bearing design should first be based on functional requirements, predict its function was reduced by the yearly changes in the extent possible, the management must maintain a minimum function of a standard set of regulations and standards in order to ensure the maintenance of this Check the frequency and content, and to restore the function of the management plan has been reduced in advance to have a perfect overall maintenance management planning. Secondly, although according to the degree of self-made changes and developments in the sphere deformed steel supports, to predict lower bearing function, a single judge and selected the exact repair methods and implementation time, etc. In fact, not only depends on bearing itself changes must also be on a one-way full-bridge design WJGZ spherical steel bearing activities, information construction and maintenance and management of the past has been cracking and master, which is to ignore the important part. Meanwhile, on the methods used to record and save data. Should also be included in the overall maintenance plan and have clearly defined particularly important. In particular bearing maintenance and management, in addition to bearing after processing must be confirmed by a variety of experiments carried out to meet the energy requirements of parts of the car, bearing in use regularly in testing and maintenance, for laminated rubber bearings The main check bearing has not happened rubber cracking KQGZ seismic grid movable spherical steel bearing, bearing the phenomenon of displacement and void if it is found should take timely and effective measures to deal with. Seismic loading piers, pier entity pier by weight in particle horizontal seismic load, flexible pier by pier weight, problems developed due to the above calculation requires Yongda power factor, because the bridge damping design, calculate seismic loads, the According to the natural cycle of damping spherical steel truss bridge abutment, the nature of different venues, to identify power amplification factor, and suggested a bridge cycle is calculated according to the following formula. Horizontal loads the gravity node as the node level displacement level bridge pier structures were taken just elastic stiffness and yield stiffness. Shock absorber damping bearing is composed by the separator, the separator is used to provide flexible support for the bridge structure, vibration dissipation ability to resist horizontal forces at the bridge structure, the group generated a bridge too large, while absorption Two that could be a whole separate set can also be a bridge structure. Currently the world's common isolation bearings can be divided into two types overall type and separation. Separated by type damping bearings usually drink can have a greater level of displacement of ordinary rubber bearing structure some form of combination, according to our research report provides general classification.
