一种螺纹连接的圆钢管柱及施工方法
摘要：
本发明涉及一种螺纹连接的圆钢管柱及施工方法，包括若干圆钢管柱单元，所述圆钢管柱单元之间在拼接段处螺纹连接，所述圆钢管柱单元与所述拼接段采用焊接链接。其中位于上段的所述圆钢管柱单元上设有使撬棍穿过的撬棍孔；当上下相邻的两圆钢管柱单元吊装就位后，通过对插入所述撬棍孔的所述撬棍施力来旋紧上段圆钢管柱单元，完成所述钢管柱单元之间的螺纹连接。该螺纹连接节点克服了现场焊接节点的低效率，低质量，受天气和气候影响等缺点。降低了对安装工人技术水平的要求，通过简单操作，即可实现圆钢管柱的拼接。
摘要（英）：

The invention relates to a circular steel tube column in threaded connection and a construction method. The circular steel tube column in threaded connection comprises a plurality of circular steel tube column units, the circular steel tube column units are in threaded connection at splicing segments, and the circular steel tube column units are linked to the splicing segments by use of welding. A circular steel tube column unit at an upper segment is provided with crowbar holes enabling crowbars to pass through; and when two circular steel tube column units adjacent to each other at an upper position and a lower position are hoisted in place, and the upper-segment circular steel tube column unit is screwed tight through applying forces to the crowbars inserted into the crowbar holes so as to finish threaded connection between the circular steel tube column units. The threaded connection pitch point provided by the invention overcomes the disadvantages of low efficiency of onsite welding pitch points, low quality, influences exerted by weather and climate and the like. The requirements for technical level of installation workers are reduced, and the circular steel tube columns can be spliced through simple operation.
