For more information:
Steel structure anti-seismic spherical steel bearings The seat is mainly composed of an upper support slide plate, a lower support plate, a ball panel, a polytetrafluoroethylene slide plate (one piece of flat ball each) and a steel retaining ring. The displacement of the sliding anti-seismic spherical bearing is realized by sliding between the upper bearing slide plate and the flat fluorine plate. By setting guide grooves or guide rings on the upper bearing slide plate to constrain the displacement direction of the bearing, it can be controlled Into one-way movable bearing and fixed bearing. The vertical angle of the spherical bearing is achieved by sliding between the spherical panel and the spherical PTFE plate. Usually, since the rotation center of the support does not coincide with the rotation center of the upper part, a second sliding surface is formed between the upper support plate and the flat PTFE. Depending on the relative position of the upper structure and the rotation center of the support, the rotation direction of the shoe surface can be consistent with or opposite to the plane sliding direction. If the two centers of rotation coincide, there will be no sliding on the plane. When the bearing rotates, it first occurs between the spherical plate and the spherical PTFE plate, and then slides on the flat PTFE plate. Therefore, the spherical bearing is particularly suitable for bridges with large rotation angle requirements.
Steel structure anti-seismic spherical steel bearing
Reliable force transmission and flexible rotation. It not only has the characteristics of large bearing capacity and large allowable displacement of basin-type rubber bearings, but also can meet the needs of large bearing angles. , compared with the pot-type rubber bearing, it has the following characteristics: the spherical bearing transmits force through the spherical surface, without force necking, and the reaction force acting on the concrete is relatively uniform. The sliding anti-seismic spherical bearing realizes the rotation process of the bearing through the sliding of the spherical PTFE plate. The rotating torque is small, and the rotating torque is only related to the spherical radius of the bearing and the friction coefficient of the PTFE plate, and is related to the rotation angle of the bearing. Nothing to do. Therefore, it is especially suitable for the needs of large corners, and the design angle can reach more than 1.
Seismic-resistant spherical steel bearings for steel structures
The rotation performance is consistent in all directions and is suitable for wide bridges, curved bridges, ramp bridges, inclined bridges, etc. The sliding anti-seismic bearing does not use rubber to bear pressure, and there is no impact of rubber aging on the rotation performance of the bearing. It is especially suitable for low temperature areas. Ball bearing product classification: Classification by performance:. Bidirectional movable bearing: with vertical rotation and longitudinal and transverse sliding properties, code-named. Divided according to applicable temperature range: Normal temperature bearing: suitable for -~℃. Cold-resistant bearing: suitable for -~℃, the code is classified according to the vertical bearing capacity (i.e., the bearing reaction force), and is divided into 3 levels, namely.,.,.,.,.,.,3.,3., ,,,,,,,.,,.,,.,,.,3.,3.,,,,and.
