Title:
制震補強方法
Document Type and Number:
Japanese Patent JP6581146
Kind Code:
B2
Abstract:
To utilize dynamical characteristics of a polyurea resin, to protect a structure from vibration due to an earthquake or the like.SOLUTION: A vibration control reinforcement structure is configured such that a reinforcement layer is formed in a tower 12 of a wind power generator 10, the reinforcement layer coating at least one of an inner surface and outer surface of the tower 12. The reinforcement layer contains a polyurea resin formed by chemical reaction of a polyisocyanate compound and an amine compound, and silica powder mixed evenly with the polyurea resin or silica powder alternately laminated with the polyurea resin. Since the reinforcement layer contains the polyurea resin and the silica powder, an attenuation constant of the wind power generator 10 can be greatly improved.SELECTED DRAWING: Figure 3
