KZQZ type ball bearing slide seismic characteristics 1, KZQZ earthquake-type ball bearing slide can be universal rotation, universal carrying unidirectional ball bearing factory Nett seismic, well positioned to meet the upper structure of the various loads (such as dead load, live load, wind, seismic forces, etc.) generated by the mass rapid reaction force, rotate, move requirements to ensure reaction force focused, clear and reliable. 2, KZQZ earthquake-type ball bearing slide can withstand tensile, compressive, shear (lateral) force in the huge random seismic force, as long as the upper and lower structure itself does not destroy, because of the presence of such holder would not have happened off the beam, landing gear and other disastrous consequences (in general, bearing a weak link in the powerful earthquake force, prone to fall off the beam or frame, and such bearing strength and ductility are higher than the structure itself) , it is especially suitable for fortification highly seismic area, the ability to be resistant to seismic intensity of 9 degrees. 3, KZQZ earthquake-type ball bearing slide compared with other support (such as laminated rubber bearing, rubber bearing basin, etc.), static stiffness, huge weight and inertia force and large cars in the train, bearing produce only minimal deformation, can reliably guarantee car, train, especially high-speed car running smoothness. 4, KZQZ type ball bearing slide seismic force transmission through the sphere, by a large force area, and the use of optimized combination of aircraft material, so the hinge structure compared with other support (such as swing bearing, roller bearing, etc.) its volume and height are greatly reduced, light weight, easy to install, and compared with the same carrying capacity of steel bearing low cost. 5, KZQZ earthquake-type ball bearing slide apply a wide range of temperature (-40 ℃ ~ + 70 ℃), good durability; do not use rubber pressure, the impact of aging on the rubber bearing rotation performance does not exist. Steel ball bearing slide installation requirements Installation requirements passenger dedicated railway bridge steel ball bearing slide as follows: (1) supporting the bearing pad stone concrete grade of not less than C40, the four corners of the top surface of the stone pad height of not more than 2mm, support pad height stone bearing for easy replacement should be considered if necessary; (2) Prefabricated simply supported box girder bearing installation, the first beam is placed on top of the pier four dynamometer jack, should ensure that each holder of Anti-reaction force and the average of four points difference of not more than 5%; (3) the location of bearing bolt embedded multi-directional seismic accurate ball bearing professional manufacturers, embedded bolt hole centerline and angular position deviation not more than 10mm; (4) Prefabricated simply supported box girder steel ball bearing slide installation process rules; steel ball bearings at the top slip structure, circular steel tube frame column using concrete columns, beams and slabs of steel - concrete composite structure The total steel than ordinary steel has drastically reduced the amount of steel, can effectively reduce the project cost. Steel construction has the advantage of its decision will certainly have a strong vitality. Steel structure, manufacturing plant based, dry construction work, short duration, high degree of industrialization, pollution, no construction waste, in line with the development trend of the construction market. With the further development of the visible steel ball bearings, steel structure worthy of use in multi-storey civil. Steel ball bearing slide member factory processing nodes bolted, high degree of automation, precision is guaranteed, dry operation, easy to control quality, reinforced concrete structure cast in situ, wet work, the quality level of a great relationship with the mechanic. Short construction period: steel factory production of finished universal seismic ball bearings offer on-site installation, simple process, a large working surface, construction speed, reinforced concrete structure should be steel banding, formwork, pouring, pounding shock, conservation and more procedure, cost of manpower and resources, long construction period.
