Self-locking split bolt and using method thereof
The invention discloses a self-locking split bolt and a using method thereof. The self-locking split bolt comprises a split rod, a locking disc and a split disc. Inverted cone teeth are arranged at one end of the opposite-pull rod, and external threads are arranged at the other end of the opposite-pull rod; the locking disc is of a circular ring structure and is provided with radial through holes, and a telescopic assembly is arranged in each through hole. The telescopic assembly comprises a telescopic tongue, a spring and an electromagnetic valve; and under the action of the spring, one end of the telescopic tongue extends out of the through hole and is matched with the inverted cone teeth of the opposite-pull rod. According to the self-locking split bolt, the split rod can be prevented from being pulled out only by inserting the split rod into the locking disc, and the split rod can be pulled out by opening the electromagnetic valve, so that the mounting and dismounting steps of the split bolt are simplified, the rotation stroke of the split disc during mounting and dismounting is shortened, and the construction efficiency is obviously improved; and operation only needs to be carried out on one side of the template, the requirement for the operation space is lowered, and the template is suitable for the situation that the operation space on one side is narrow.
本发明公开了一种自锁式对拉螺栓及其使用方法，所述自锁式对拉螺栓包括对拉杆、锁紧盘和对拉盘。所述对拉杆的一端设置有倒锥体齿牙，另一端设置有外螺纹；所述锁紧盘为圆环结构，设置有径向的通孔，每个通孔内均设置有一组伸缩组件；所述伸缩组件包括伸缩舌、弹簧和电磁阀；在弹簧作用下，所述伸缩舌的一端伸出通孔并与所述对拉杆的倒锥体齿牙相配合。该自锁式对拉螺栓，仅需将对拉杆插入锁紧盘中，即可防止对拉杆拔出，开启电磁阀即可拉出对拉杆，简化了对拉螺栓的安装和拆除步骤，缩短了对拉盘在安装和拆除时的转动行程，明显提高了施工效率；且仅需在模板的一侧进行操作，降低了对操作空间的要求，适用于一侧操作空间狭小的情况。
