柔軟性モルタル３で被覆してある。FIG. 1 shows a vibration-proof structure of a long member according to the present invention. In this long member 1, upper and lower flanges 2a and 2b made of ordinary steel are integrally connected by a web 2c at their centers. The outer circumference of the H-shaped steel 2 is covered with a flexible mortar 3 as a vibration absorber.

吸収する。The flexible mortar 3 is preferably a mixture of ferritic cement and resin. As a manufacturing method thereof, after assembling the shape steel 2 with other members at the construction site, the flexible mortar 3 is applied to the outer periphery thereof to complete the vibration-proof structure, and vibration is applied to the long member 1. And the flexible mortar 3 converts the vibration into heat energy and absorbs the vibration.
