EARTHQUAKE-PROOF M-SHAPED FRAME FOR UPPER FLOOR OF STEEL STRUCTURE
To provide an earthquake-proof frame formed in a compact size.SOLUTION: An earthquake-proof M-shaped frame for an upper floor of a steel structure 4 is formed by welding connecting a first steel column 11 and a second steel column 12, which are formed of square steel tubes having the same shape and disposed in parallel, to roughly ends of four braces 33, 34, 35, 36 formed of square steel tubes into an M shape to the top end plate for fixing brace 28, the vertical center plate for fixing brace 29, and the bottom end plate for fixing brace 30, which are welded and connected to the first steel column 11, and to the upper plate for fixing brace 31 and the lower plate for fixing brace 32, which are welded and connected to the second steel column located to face the first steel column.SELECTED DRAWING: Figure 4
【課題】コンパクトに形成した耐震フレームを提供する。【解決手段】同一形状の正方形の角形鋼管で成形した、平行する第１の鉄骨柱１１と第２の鉄骨柱１２と、第１の鉄骨柱１１に溶接接合した前記ブレース固定用上端部プレート２８と前記ブレース固定用上下中央部プレート２９と前記ブレース固定用下端部プレート３０と、向い合せに位置する第２の鉄骨柱に溶接接合した前記ブレース固定用上側プレート３１と前記ブレース固定用下側プレート３２に、正方形の角形鋼管で成形した４本のブレース３３、３４、３５、３６の概ね端部をＭ字形に溶接接合した鉄骨構造上階用耐震Ｍ形フレーム４を提供する。【選択図】図４
