JIN LEI / ZHU HONGYING / LEI DONG / YANG XU / CHEN YAN

The invention discloses a butt joint structure and a butt joint method of steel pylon segments, the butt joint structure comprises a first segment, a second segment and a laser positioner, the first segment is provided with a first butt joint part used for butt joint, the second segment is provided with a second butt joint part in butt joint with the first butt joint part, and the laser positioner is provided with a second butt joint part used for butt joint with the second butt joint part. And the laser positioner is arranged on the first butt joint part and/or the second butt joint part, and is suitable for performing positioning adjustment on the first section and the second section through the laser positioner. Therefore, on one hand, through the arrangement of the first butt joint part and the second butt joint part, rapid and preliminary locking after accurate butt joint of the first section and the second section can be achieved, the butt joint error caused by human or external factors after accurate positioning of the steel cable tower section is completed is reduced, and the construction efficiency is improved; rapid and accurate positioning between the sections of the steel cable tower can be achieved, the butt joint precision and the use efficiency are improved, and the design precision requirement of tower forming linearity can be met.

本发明公开了一种钢索塔节段的对接结构以及对接方法，所述对接结构包括：第一节段、第二节段以及激光定位器，第一节段上设置有用于对接的第一对接部，第二节段上设置有与第一对接部对接的第二对接部，激光定位器设置于第一对接部和/或第二对接部，并适于通过激光定位器对第一节段与第二节段进行定位调整。由此，一方面，通过设置第一对接部与第二对接部，可以实现第一节段与第二节段精确对接后的快速、初步锁定，降低钢索塔节段完成精确定位后，受到人为或外界因素产生的对接误差，以提高施工效率，另一方面，利用激光定位器，可以实现钢索塔节段之间的快速、精准定位，提高了对接精度以及使用效率，并可以保证成塔线性的设计精度要求。
