EARTHQUAKE RESISTANT REINFORCEMENT METHOD AND REINFORCEMENT DEVICE OF EXISTING BUILDING
PROBLEM TO BE SOLVED: To provide an earthquake resistant reinforcement method and a device capable of economically reinforcing a building of a steel frame structure in a short construction period while using a floor surface.SOLUTION: A rail 20 extending up to a predetermined position P1 opposed to a use-time floor surface 11 from a position P2 opposed to an empty floor surface 12, is arranged on a roof 3 of an existing building 1 of a steel frame structure, and a suspension device 30 is installed in the predetermined position vicinity Q1-Q6 of the roof 3, and a reinforcement steel frame 6b is slidably moved along the rail 20 from the empty floor surface 12, and the reinforcement steel frame 6b slidably moved up to a position Q1-Q6 of the suspension device 30 is re-hooked on the suspension device 30, and suspended up to the roof 3, and the roof 3 is reinforced by joining the suspended reinforcement steel frame 6b to an existing steel frame (a steel frame column 15 in an illustrated example). For example, the rail 20 is formed as a trolley beam joined via a suspension material 22 to an existing steel frame 5a of the roof 3, and a sliding movement device 40 is formed as a hoist slidably movably suspended by the trolley beam.SELECTED DRAWING: Figure 1
【課題】床面を使用しながら鉄骨造の建屋を短工期で経済的に補強できる耐震補強工法及び装置を提供する。【解決手段】鉄骨造の既存建屋１の屋根３に空き床面１２と対向する位置Ｐ２から使用中床面１１と対向する所定位置Ｐ１まで延びるレール２０を配置し，屋根３の所定位置近傍Ｑ１〜Ｑ６に吊上げ装置３０を設置し，空き床面１２から補強鉄骨６ｂをレール２０に沿ってスライド移動させ，吊上げ装置３０の位置Ｑ１〜Ｑ６までスライド移動させた補強鉄骨６ｂを吊上げ装置３０に掛け直して屋根３まで吊上げ，吊上げた補強鉄骨６ｂを既存鉄骨（図示例では鉄骨柱１５）と接合することにより屋根３を補強する。例えばレール２０を屋根３の既存鉄骨５ａに吊材２２を介して接合されたトロリービームとし，スライド移動装置４０をトロリービームにスライド移動可能に吊設されたホイストとする。【選択図】 図１
