Guo Heng rubber and plastic are recommended by bridge bearing manufacturers.
Bridge bearings can be divided into longitudinal moving bearings, transverse moving bearings, multidirectional moving bearings and fixed bearings according to the moving direction. On highway bridges, lateral and longitudinal movements are generally called one-way movable bearings.
Bridge bearings can be divided into highway bridge bearings and railway bridge bearings according to different bridge uses. According to the structure type, it can be divided into four categories: basin rubber bearings (GPZ, JPZ, GCPZ, etc. ), plate rubber bearings and spherical steel bearings (QZ, JQZ, GCQZ, etc. ) and cast steel bearings (articulated shaft bearings). According to the needs of earthquake resistance, various types of bearings derive from earthquake-resistant basin bearings (GPZ(KZ)) and earthquake-resistant ball bearings (QZ(KZ)).
At present, there are two main types of railways: basin support and ball support.
