Title:
CIVIL ENGINEERING ANTI-SEISMIC STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/118577
Kind Code:
A1
Abstract:
A civil engineering anti-seismic structure addresses the problem in which the conventional building foundation and pillars are an integrated structure adopting a rigid joint vulnerable to seismic damages. The structure comprises a base (1). A fixing structure (2) is fixedly welded at the bottom of the base (1) at the center. A through-hole (6) is provided at the top of the base (1) at the center. Sliding grooves (7) are provided on corresponding inner walls at two sides of the base (1). Sliding blocks (10) are slidably connected to the sliding grooves (7) inside the grooves and are symmetrically installed at two sides of a sliding plate (8). A top block (3) is fixedly welded at the top of the sliding plate (8) at the center, and a fixing groove (4) is provided at the top of the top block (3) at the center. A shock-absorbing damping pad (9) is fixedly adhered to a bottom inner wall of the base (1). A first limiting plate (13) is fixedly welded around the top portion of the sliding plate (8), and a second limiting plate (12) is fixedly welded around the through-hole (6) at a top inner wall of the base (1).
