Document Type and Number:
WIPO Patent Application WO/2022/142187
Kind Code:
A1
Abstract:
A steel spring vibration isolator pre-buried outer cylinder for floating a road bed plate, comprising a cylinder main body (1), a jacking plate (2), a supporting plate (3), fixed pins (5), and a reinforcing guard ring (4). The cylinder main body (1) is a cylindrical thin-walled cylinder component connected to each component; the jacking plate (2) is provided at the upper portion of the cylinder main body; a triangular hole and threaded holes are formed in the jacking plate (2); the triangular hole is used for mounting a steel spring vibration isolator (6) and a jacking tool; the threaded holes are used for mounting a protective cover plate (10) covering an upper surface; the supporting plate (3) is provided in the middle of the cylinder main body and used for mounting the steel spring vibration isolator (6), and has the functions of supporting and limiting; the reinforcing guard ring (4) is provided at the bottom of the cylinder main body; and when the outer cylinder is pre-buried into concrete and has the function of reinforcement, four fixed pins (5) are arranged on the outer ring of the cylinder main body and used for fixing and limiting the position of the outer cylinder during concrete pouring.
