Method of reinforcing existing bridges, a base integral reinforcing member used therein, the reinforcing structure of existing bridges

摘要

PROBLEM TO BE SOLVED: To provide a member-bonding technique enabling bonding between various kinds of materials, e.g. bonding between members made of metals, bonding between members made of concrete, bonding between members between wood, bonding between a member made of metal and a member made of concrete, bonding between a member made of metal and a member made of wood and bonding between a member made of concrete and a member made of wood, being utilizable to not only bonding between planar members, but also to bonding between members having various kinds of shapes, structures and sizes, bonding between a planar member and a three-dimensional member and bonding between three-dimensional members and not only solving the above various kinds of problems, but also achieving adhesive effect such as improvement of adhesive strength and toughness which is superior than adhesive effect obtained directly bonding members to each other with an adhesive by selecting an adequate impregnation material.;SOLUTION: The member bonding technique comprises interposing an adhesive-impregnated substrate between members to be bonded. As a result, whole area can be bonded and adhesive strength is improved and toughness is exhibited. The member for bonding, in which a substrate is impregnated with an adhesive or the substrate is not impregnated with the adhesive, is obtained by attaching a substrate or/and a backup material to a surface of either one member to be bonded. The member-bonded structure is obtained by bonding members in a state in which an adhesive-impregnated substrate is interposed between members.;COPYRIGHT: (C)2008,JPO&INPIT
