GAS PRESSURE-CONTACTED REINFORCEMENT COUPLER AND REINFORCEMENT CONNECTION METHOD OF USING THE SAME
PROBLEM TO BE SOLVED: To provide a gas pressure-contacted reinforcement coupler and a reinforcement connection method of using this coupler, capable of effectively suppressing HAZ rupture on a reinforcement even when using a high strength reinforcement.SOLUTION: A steel pipe coupler 1 is composed of an outside pipe 11 of a substantially cylindrical shape in an external shape having a first straight part 111 in an inner surface rear part, having a taper part 112 of expansively opening outward in an inner surface intermediate part adjacent to the first straight part 111 and having a second straight part 113 for diametrically expanding an inner diameter more than the first straight part 111 and forming a female screw part A in an inner surface front part adjacent to the taper part 112 and an inside pipe 12 of a substantially cylindrical shape in an external shape having a male screw B threadedly engaging with the female screw A formed in the second straight part 113 of this outside pipe 11 in an outer surface front part, having a straight part 121 in an inner surface rear part and having a taper part 122 for expansively opening outward in the inner surface front part adjacent to the straight part 121, and is provided with a structure capable of including a swelling C formed in a reinforcement by forming an inner-outer double pipe structure in a part.SELECTED DRAWING: Figure 3
【課題】 高強度鉄筋を用いた場合においても、鉄筋についてHAZ破断を有効に抑止することのできるガス圧接した鉄筋用のカプラーと、該カプラーを用いた鉄筋の連結方法とを提供すること。【解決手段】 内面後部に第１ストレート部１１１を備え；第１ストレート部１１１に隣接する内面中間部には外方に拡開するテーパー部１１２を備え；テーパー部１１２に隣接する内面前部には、第１ストレート部１１１より内径が拡径され、かつ、雌ネジＡが形成されている第２ストレート部１１３を備えた；外形が略円筒状の外側管１１と；この外側管１１の第２ストレート部１１３に形成されている雌ネジＡに螺合する雄ネジＢを外面前部に備え；内面後部には、ストレート部１２１を備え；ストレート部１２１に隣接する内面前部には外方に拡開するテーパー部１２２を備えた；外形が略円筒状の内側管１２と；からなる、一部が内外二重管構造をなし、鉄筋に形成されたふくらみＣを内包しうる構造を有する、鋼管製のカプラー１を提供する。【選択図】 図３
