ROTATION-RESTRAINING STRUCTURE FOR TENDON COUPLER, AND TENDON COUPLER
PROBLEM TO BE SOLVED: To prevent a whole or a part of a coupler from rotating around an axis due to untwisting action of a twisted steel strand.SOLUTION: A tendon coupler includes a steel sleeve 15 as an edge part connecting member fixed on an edge part of a second tendon 2 made of a twisted steel strand, the tendon coupler connecting the second tendon with a first tendon 1 through the steel sleeve. The steel sleeve has a first engaging member 20 fixed thereon, and the second engaging member 30 is fixed on a concrete member 15, which is a stationary member that cannot be displaced. The first and second engaging members have square pipe parts 22, 32 protruding to face each other, and the square pipe part 22 of the first engaging member is inserted into the square pipe part 32 of the second engaging member. Thus, a movement of the tendon coupler in an axis direction of the second tendon is allowed, while rotation of the steel sleeve around the axis of the second tendon is restrained as the two square pipe parts come in contact with each other.SELECTED DRAWING: Figure 1
【課題】鋼より線の撚り戻し作用によって接続具の全体又は一部が軸線回りに回転するのを防止する。【解決手段】緊張材接続具は、鋼より線である第２の緊張材２の端部に固着される端部結合部材として鋼スリーブ１５を備えており、該鋼スリーブを介して第２の緊張材を前記第１の緊張材１と接続する。鋼スリーブには第１の係合部材２０を固着し、位置が不動となった固定部材であるコンクリート部材１５に第２の係合部材３０を固着する。第１の係合部材と第２の係合部材とは、対向するように突き出した角管部２２，３２を有し、第１の係止部材が有する角管部２２を第２の係止部材が有する角管部３２の内側に挿入する。これにより、緊張材接続具が第２の緊張材の軸線方向へ移動するのを許容するとともに、鋼スリーブが第２の緊張材の軸線回りに回転しようとしたときには２つの角管部が接触して該鋼スリーブの回転を拘束する。【選択図】図１
