A INSERT-TYPE MEMBER FOR REINFORCING A VARIANT PROFILED HOLLOW MEMBER HAVING CLOSED-LOOP SHAPED CROSS SECTION AND THE USING METHOD THEREOF

摘要

The present invention relates to an insertion-type reinforcing member for a closed section member with a variable profile which can simply reinforce the inside of the member without cutting the member. The insertion-type reinforcing member (50) for reinforcing a closed section member (10) with a variable profile according to the present invention comprises a first member (51) and a second member (52) which are disposed to extend or reduce a distance between the first and second members to be matched to the variable direction of the profile. The first member and the second member are elastically supported in the direction away from each other. The first member holds a built-in bolt (55) whose head unit faces the second member, and whose shaft part extends in the opposite direction of the direction facing the second member to penetrate a bolt hole (54) formed in the first member. A wire is connected to one side of at least one among the first member and the second member.
