PURPOSE:To prevent a panel from coming out of support member by locking a large diameter hook-shaped engaged part installed on one of the side plates of a channel panel to the support member and pressing a small diameter hook- shaped engaged part installed on the other side plate of the next panel into the large diameter engaged part. CONSTITUTION:A large diameter engaged part 21 bent outward in hook shape is formed on one of the both side plates 20 of a panel 2, and a small diameter engaged part 22 bent inward in hook shape is formed on the other side plate. Next, when the panel 2 is installed on a support member 1 fixed to a bed member, the large diameter engaged part 21 is locked so that it is inserted slightly into the lower side of the locking and protruding part 11 of the support member 1. Also the large diameter engaged part 21 of the next panel 2 is locked to the locking protruding part 11 of the next support projection 10 in order. In this case, the small diameter engaged part 22 is fitted closely into the large diameter engaged part 21 while it is pressed between the top side plate 20 of the next already fixed panel 2 and the locking and protruding part 11 there. Thus the panel can be prevented from being coming out of the support member, and the water tightness can be improved. |
