The utility model discloses a novel building shock insulation support who adopts the all -metal to make, it includes upper bracket board, bottom suspension bedplate and install between upper bracket board and bottom suspension bedplate and rather than the complex spherical crown, the spherical crown is used for being provided with a plurality of lubrication grooves with upper bracket board, bottom suspension bedplate complex working face, and lubricated intussuseption is filled with emollient. The utility model discloses because it adopts the all -metal manufacturing, the bearing capacity is strong, and the durability is good, and resistance to corrosion is strong to having fireproof capacity, under big difference in temperature effect such as conflagration, still keeping bearing capacity, long service life in addition, also need not to inlay the antifriction plate at the spherical crown working face, can guarantee the coefficient of friction of spherical crown and upper bracket board and bottom suspension bedplate through self performance of material.
