BUCKLING RESTRAINT BRACE MANUFACTURING METHOD AND ROTATION JIG

To provide an efficient method for manufacturing a buckling restraint brace.SOLUTION: There provided is a method for manufacturing a buckling restraint brace which includes: a first process in which a first core material 310 is placed on a first jig 1000, a second core material 320 is welded to the first core material 310, and the first core material 310 is provided with an unbonded material 330; and a second process in which the first jig 1000 on which a core material 300 provided with the unbonded material 330 is arranged, and a second jig 2000 on which a steel pipe 200 is arranged are relatively moved to approach, and the core material 300 is inserted into the steel pipe 200 on the second jig 2000. And in the first step, after welding the second core material 320 to the first core material 310, the core material 300 is rotated on the first jig 1000, and then the unbonded material 330 is provided on the first core material 310.SELECTED DRAWING: Figure 7 【課題】効率的な座屈拘束ブレースの製造方法を提供する。【解決手段】座屈拘束ブレースの製造方法であって、第１治具１０００の上に第１芯材３１０を配置し、第１芯材３１０に第２芯材３２０を溶接するとともに第１芯材３１０にアンボンド材３３０を設ける第１工程と、アンボンド材３３０が設けられた芯材３００が配置された第１治具１０００と、鋼管２００が配置された第２治具２０００と、を移動して相対的に接近させ、芯材３００を第２治具２０００の上の鋼管２００の中に挿入する第２工程と、を備え、第１工程では、第１芯材３１０に第２芯材３２０を溶接した後、第１治具１０００の上で芯材３００を回転させ、その後、第１芯材３１０にアンボンド材３３０を設ける。【選択図】図７
