    • A tie rod 3 is screw-threadedly engaged within a threaded member 7 carrying a cone 8 which, together with a further cone 10, acts to expand a slitted expandable sleeve 9 when the rod 3 is rotated by a tool applied to a square cross-section tip 21 so that the threaded member 7 is driven towards a fixed head 6 on the rod 3. The threaded member 7 carries a securing member 16 having projecting ribs which hold the threaded member 7 against rotation within a bore hole 20B as the rod 3 is rotated. The other end of the rod 3 is secured within a bore 20A of a double skin cavity wall by rotating a nut 11 to cause a slitted expandable sleeve 13 to expand into the wall of the bore 20A due to action of conical members 12 and 14.
    • 拉杆3螺纹地接合在带有锥体8的螺纹构件7中,螺纹构件7与另外的锥体10一起作用以在通过施加到正方形截面的工具旋转杆3时使切割的可扩张套筒9膨胀, 截面尖端21,使得螺纹构件7朝向杆3上的固定头6被驱动。螺纹构件7承载具有突出肋的固定构件16,该突出肋保持螺纹构件7在杆3内在孔眼20B内不旋转 旋转 通过旋转螺母11将杆3的另一端固定在双皮腔壁的孔20A内,以使得由于圆锥形构件12和14的作用使切割的可扩张套筒13膨胀到孔20A的壁中。

    • The tie comprises a rod (1) with threaded end portions (2,3) of opposite hand. Threaded end portion (2) has at each end an anchoring assembly (4) and (4a), respectively. One anchoring assembly (4) comprises first frustoconical member (5) and second frustoconical member (6), each of which has a respective inwardly tapering surface (7,8) and a respective inwardly facing transverse end face (9,10). Located between the frustoconical members is a tubular sleeve (11), which is provided with an inwardly projecting radial lug (11a), arranged to engage transverse end face (10) and resist an applied force which would otherwise tend to pull the frustoconical member (6) through the sleeve (11).
    • 领带包括具有相对的手的螺纹端部(2,3)的杆(1)。 螺纹端部(2)分别在每个端部具有锚固组件(4)和(4a)。 一个锚固组件(4)包括第一截头圆锥体构件(5)和第二截头圆锥形构件(6),每个构件具有相应的向内渐缩表面(7,8)和相应的向内的横向端面(9,10)。 位于截头圆锥形构件之间的管状套筒(11)设置有向内突出的径向凸耳(11a),其布置成接合横向端面(10)并抵抗施加的力,否则其将倾向于拉动截头圆锥体构件 6)穿过套筒(11)。
