With the development of technology, highway bridges, bridge bearing types are constantly updated and increased until the 1960s, we can say the larger highway bridge bearing almost all type of steel reinforced bearing drink Concrete bearing bridge rubber bearing, almost exclusively for small span bridges with a simple method for processing (such as oil blankets, etc.). With the development of the chemical industry, the emergence of rubber bearings drink using PTFE slide rubber bearing sliding bearing plane, by the early 1960s began, laminated rubber bearings and rubber bearing basin gradually into the development and application, especially in the 20th century, 80 to 90 years, have worked out a highway bridge culvert design standard drawings (1980). transportation industry standard "highway bridges laminated rubber bearing specifications series" (JT 3132.1-88), "highway bridge laminated rubber support Block technical conditions "(JT 3132.2-88)," highway bridge mechanical properties of the finished laminated rubber bearings inspection rules "(JT 3132.3-90) and" highway bridge pot bearings "(JT 3141-90) issued and implemented, making pot bearings will soon become the main highway bridge abutment form. Abroad in the 1970s started to develop spherical bearings, and soon in the curved bridge applications. Germany prestressed concrete bridge built in recent decades the use of bearing condition were investigated gyzf4 rubber bearings, the results indicate that in 1964 before the rubber bearing gjz, 100% of the bridge with steel supports, from 1958 began to use pot bearings, in 1970 began after extensive use of pot bearings, pot bearings and bearing all proportion the amount is growing. For discount off bridge girder bridge, in the middle of the main beam bending fulcrum continuous beam forms bearing arrangement. To bend the bridge and the bridge of subject, but the activity is generally assumed to be the direction of the chord direction. Direction of rotation bearing, thanks Angular two aliquots direction, it is possible to reduce the rotation around the beam generated binding. Using the support plate rolling bearing axes drink holder can eliminate this problem. Wide bridge is not parallel to the bridge and the bridge is not parallel with respect to the wide bridge, beam spacing changes are not parallel beam bearing arrangement, according to Figure consideration, then, for any case in support line all want the same arrangement in a certain direction stand. Moving in the width direction, since the lower structure is also telescopic, it is generally not considered necessary. However, the width of the bridge deck bearing lateral spacing must become larger as the need to ensure that measures the lateral displacement, layout examples bearing in this case, because the role of a larger lateral horizontal force, it must be noted .
