| 摘要 |
The present invention relates to a high-load disk bearing which is provided to increase compressive stress by preventing an elastic rubber part formed for a bridge bearing from protruding to the outside from a bridge deck to which heavy load is applied, and which comprises: an upper plate (10) combined with a bridge deck; a lower plate (20) combined with a pier (2); an elastic rubber part (30) that is disposed between the upper plate (10) and the lower plate (20) and which uses elastic force for supporting the load applied to the upper part of the bridge deck; an inner plate (31) formed inside the elastic rubber part (30); an upper support plate (32) provided on the upper part of the elastic rubber part (30) corresponding to the upper plate (10); and a lower support plate (33) formed on the lower part of the elastic rubber part (30) corresponding to the lower plate (20). The upper and lower support plates (32, 33) have the lengths longer than that of the inner plate (31). The support plate (32) has a first protrusion (32a), which protrudes downwardly, formed along the circumferential edge thereof; and the lower support (33) has a second protrusion (33b), which protrudes upwardly, formed along the circumferential edge thereof. |
