3.1 Definition
This standard adopts the following definitions
Rubber isolation bearings for buildingsIsolation devices composed of multiple layers of rubber and multiple layers of steel plates or other materials alternately stacked togetherDesign working lifeThe period during which a rubber isolation bearing for buildings does not lose its effective function under normal use and maintenance conditions. 3.2 Classification and Type
3.2.1 Classification
Building rubber bearings can be divided into two types: ordinary type (coreless type) and core type according to whether there is a core in the middle hole. The cross-sectional shape of building rubber bearings is generally circular or rectangular. Approved by the Ministry of Construction of the People's Republic of China on May 10, 2000 and implemented on December 1, 2000
