Magnetic type damping bridge support
The invention belongs to the technical field of bridge supports, and particularly relates to a magnetic type damping bridge support. The magnetic attraction type damping bridge support comprises an upper support plate, a lower support plate and a spherical crown lining plate arranged between the upper support plate and the lower support plate, a plane sliding friction pair is arranged between the upper support plate and the spherical crown lining plate, a spherical sliding friction pair is arranged between the lower support plate and the spherical crown lining plate, and a magnetic attraction mechanism is arranged in the plane sliding friction pair and/or the spherical sliding friction pair. The magnetic attraction mechanism comprises a clamping groove formed in the bottom face of the upper support plate or the top face of the lower support plate, a groove hole corresponding to the clamping groove is formed in the plane sliding friction pair or the spherical sliding friction pair, and a neodymium iron boron magnet is arranged in the clamping groove. The magnetic attraction type damping bridge support is particularly suitable for the transverse wind resistance condition of a large-span bridge, and has the advantages of being good in transverse wind resistance and good in magnetic attraction type damping effect.
本发明属于桥梁支座技术领域，具体的讲涉及一种磁吸式阻尼桥梁支座。该磁吸式阻尼桥梁支座包括上支座板、下支座板以及置于二者之间的球冠衬板，上支座板与球冠衬板之间设有平面滑动摩擦副，下支座板与球冠衬板之间设有球面滑动摩擦副，平面滑动摩擦副和/或球面滑动摩擦副内设置磁吸机构，磁吸机构包括设置在上支座板底面或下支座板顶面的卡槽，平面滑动摩擦副或球面滑动摩擦副上设有与卡槽对应的槽孔，卡槽内设置钕铁硼磁铁；该磁吸式阻尼桥梁支座特别适用于大跨度桥梁横向抗风条件，具有良好的横向抗风能力，磁吸式阻尼效果好的特点。
