  • Bearing structure with isolation and anchor device
    Patent number: 5452548
    Abstract: The present invention is concerned with the improvement of bearings for use in supporting bridges or large-scale buildings. The invention comprises combining the advantages of a conventional metal bearings with synthetic rubber bearings to improve vertical resistance as well as horizontal and torsional rigidity under reciprocal seismic load. Relatively simple and inexpensive products are used to produce the invention.The invention is formed with the multilayer pattern of having metal plates as a bearing unit and metal bars, located in the center of the bearing unit, which anchor the top and bottom bearing plates so as to limit horizontal displacement. It utilizes synthetic rubber for sealing bearing units to protect the metal bearing units from corrosion.
