<p>PROBLEM TO BE SOLVED: To provide an opening reinforcement structure by which high reinforcing performance can be obtained at an opening, and which can be easily applied to an existing architectural structure.SOLUTION: The opening reinforcement structure has a portal reinforcement component 4 for reinforcing an opening 3 of an outer wall 2 of an architectural structure. The reinforcement component 4 includes: a pair of column structures 10, 10 erected along the opening 3; and a beam structure 20 for connecting upper parts of the column structures 10. The column structure 10 has a truss column 14 including a pair of longitudinal chord members 11, 11 and a plurality of diagonal members 12, 12... bridged between the longitudinal chord members 11, 11. The beam structure 20 has a truss beam 24 including a pair of lateral chord members 21, 21 and a plurality of diagonal members 22, 22... bridged between the lateral chord members 21, 21.</p> |
