<p>PROBLEM TO BE SOLVED: To provide an angle steel reinforcement device and an angle steel reinforcement execution method capable of reinforcing existing angle steel using the minimum materials, shortening of work time, and reducing cost of reinforcing work, without adding any working to the existing angle steel constituting a truss structure.SOLUTION: A reinforcement plate material 20 is disposed inside an opening 113 of existing angle steel 11 along a longitudinal direction of the angle steel, and in this state, first and second metal fixtures 301 and 302 are plane-symmetrically disposed so as to hold both sides 111 of an L-shape of the existing angle steel 11 between them from the outside face. A first fixing part 301d of the first metal fixture and a second fixing part 302d of the second metal fixture are fixed to the reinforcement plate material 20 with first fixing bolts and nuts 303. A first fastening part 301b of the first metal fixture and a second fastening part 302b of the second metal fixture are fastened in a direction of approaching each other with first fastening bolts and nuts 304, so that the reinforcement plate material 20 is integrally fixed to the angle steel 11.</p> |
