Abstract
The invention discloses a shock absorbing building structure. The shock absorbing building structure comprises an upper beam body and a lower beam body, wherein an asphalt sand cushion layer is laid between the upper beam body and the lower beam body; a plurality of equally-spaced rubber rods are arranged at the same horizontal height; one ends of the rubber rods extend into the upper beam body; the other ends of the rubber rods extend into the lower beam body; and two U-shaped grooves form a rectangular cavity. A sliding shaft is arranged in the rectangular cavity; and shock absorbing components are arranged on the upper side, the lower side, the left side and the right side of the sliding shaft. The interior of the sliding shaft is a hollow body and filled with a flexible glue. The shock absorbing components comprise connecting blocks, fixed blocks and sliding blocks, wherein one sides of the connecting blocks are arc surfaces connected with the radial external surface of the sliding shaft; and the other sides of the connecting blocks are fixedly connected with the fixed blocks. Shock absorbing spring groups are arranged between the fixed blocks and the sliding blocks; and the sliding blocks are connected with the internal side of the rectangular cavity in a sliding way. According to the shock absorbing building structure disclosed by the invention, as the sliding blocks, the rubber rods and the shock absorbing springs are arranged, the bearing force, rigidity, damping and effective displacement of a shock absorbing cross beam are controlled so that an obvious shock absorbing effect on an upper structure can be exerted.
