PROBLEM TO BE SOLVED: To provide the opening part reinforcing tool of a panel without any need for cutting the reinforcing frame of the panel by expandably joining a sub-lever for a main lever and fixing an entire length from the other end of the main lever to the other end of the sub-lever. SOLUTION: At the time of use, the entire length L of an opening part reinforcing tool A is reduced by loosing a butterfly nut 52, and inserted between the ends of a channel steel with a lip provided on the opening end of the opening part of a panel. Next, a sub-lever 5 is moved from a main lever 4, the entire length L of the tool A is enlarged, and the insertion part 42 of the main lever 4 is inserted in the end of the channel steel with the lip. The insertion part 42 of the sub-lever 5 is inserted in the end of the channel steel with the lip, and the tool A is fixed on the opening end of the opening part of the panel by tightening the butterfly nut 52. Thus, need for cutting the frame of the panel is eliminated after the two panels are joined in the conventional, execution is facilitated, and fear for damaging is eliminated to be safe. |
