Opposite-pull screw
According to the opposite-pull screw rod provided by the invention, the inner screw rod is arranged in the cylindrical outer screw rod in a screw thread sleeving manner, and the wedge-shaped block isarranged between the pointed body of the inner screw rod and the body, so that the wedge-shaped block is hinged to the rear end of the pointed body through the compression spring and can be matched with the conical inclined surface of the outer screw rod;when the opposite-pull screw rod needs to be placed into a wall building template, the pointed body is used as the front end to penetrate into the inner side and the outer side of the wall building template, the outer screw rod is screwed forwards, the wedge-shaped block is jacked up by the conical slope of the outer screw rod, then the largenut at the rear end of the outer screw rod is adjusted to abut against the outer side of the back edge of the building template, and then the opposite-pull screw rods are fastened to the two sides ofthe building template. When the vertical wall is built and the opposite-pull screw needs to be dismounted, the wedge-shaped block is closed, so that the closed opposite-pull screw is pulled out of thebuilding formwork, the opposite-pull screw can be dismounted under the building formwork operation platform at high altitude without dismounting a nut buckle at the head of the opposite-pull screw, the safety coefficient is high, and repeated utilization of the opposite-pull screw is achieved.
本发明提供一种对拉螺杆，通过将内螺杆丝扣套设在筒状的外螺杆内，再在内螺杆的尖状体与本体之间设置楔形块，使楔形块通过压缩弹簧铰接在所述尖状体的后端，并且可与外螺杆的锥斜面相吻合，当需将对拉螺杆置入墙体建筑模板时，只需使尖状体作为前端穿入墙体建筑模板的内外侧，向前拧动外螺杆，使外螺杆的锥斜面顶起楔形块，而后再调节外螺杆后端的大螺母，使大螺母紧靠在建筑模板背楞的外侧，进而将对拉螺杆紧固在建筑模板的两侧，当立墙筑成需要拆除对拉螺杆时，使楔形块闭合，从而将闭合的对拉螺杆抽出建筑模板，实现在高空无需卸掉对拉螺杆头部螺母卡扣即可使对拉螺杆在建筑模板操作平台下拆除，安全系数高并且实现对拉螺杆的反复利用。
