The central part web of the upper horizontal frame located on the upper side of the frame member 5 and the both end part webs of the lower horizontal frame located on the lower side are reinforced with stiffeners. moreover,
A shearing panel 7 is hung down and fixed to the center part of the upper horizontal frame of the frame member 5, and phrases 8 rising obliquely upward from both ends of the lower horizontal frame are connected and fixed to the hanging ends of the shearing panel 7.
