Ball bearing seismic movable spherical steel bearing, will be with the project structure continues to expand, its use will continue to expand the scope and with the progress of science and technology, new materials appear, improvement and development process, and the ball form-type bearings are not limited to stroke the rubber material, while the use of other forms of elastomers, and construction will continue to emerge and develop, so consider using the formula, you should pay attention to new materials, new processes for structural and latest products . Bearing ball bearing is mainly made of steel castings or steel processing, in the past, is generally used as a bridge abutment using a spherical steel bearing, ball bearing type examination rolling steel parts, swing and slide to accommodate bridge displacement and rotation. Rubber bearing structure according to its use and there are multiple types of bearing capacity is characterized by his ability, can use a variety of bridge displacement and rotation needs, and on the great rebates and a large displacement of the support beams and has a very negative rebates good use, before the 1960s, mostly small and medium-span bridges use steel bearings, bearing large tonnage highway bridge now use pot, rubber bearing more, but people generally use steel railway bridge abutment, commonly The steel bearings are steel bearings and special bearings and so on. Ball bearings early high compressive strength, allow early bearing, non-toxic, non-corrosive, ready to use, easy to use, relatively low prices, performance, construction and precautions, surface treatment, surface perfusion should be very clean, solid free of oil, grease, cement, rubber bearing clumps and loose material, ball bearing metal surfaces require no peeling, rust, oil and grease fixed spherical steel bearing, spherical bearing absorbent surfaces must be thoroughly penetrate and no water resistance. Call and, in order to obtain the desired viscosity, the powder is added to a pre-measured amount of water, the ambient temperature of 30 degrees Celsius, in order to obtain false water flow freely and privately owned flat filling, low speed rough paste with a suitable unidirectional activity spherical steel bearing material, rubber bearings adjusted evenly, construction, pulp can be mixed perfusion, ball bearings and ensure freedom of escaping gas, when the base filling, moisten first, and keep enough pressure continuous flow of slurry. The templates must be installed to ensure a solid, impermeable, with chains, sticks or other tools compacted pulp vibrator, completely exclude air. Special precautions, ball bearing smallest gap is 10mm, non-shrink grout temperature requirements same as ordinary concrete.
