广州体育馆训练馆(含行政管理大楼、餐厅及喷水池)工程由广州市第三建筑工程有限公司承建。该工程结构错综复杂,由于施工条件的影响,多个部位必须采取分段、分层不连续施工,非正常留设施工缝处的钢筋连接,成为一个难题。采用了镦粗直螺纹连接不仅解决了该难题,加快了施工进度,而且质量稳定,安全系数大,又节省钢材。实践证明,这是一种理想的钢筋接头施工方法。 Guangzhou Gymnasium Training Center (including administrative buildings, restaurants and fountains) project by the Third Guangzhou Municipal Construction Engineering Co., Ltd. contractor. The structure of the project is complicated. Due to the influence of construction conditions, multiple sites must be subdivided into sections and discontinuously and discontinuously constructed. It is a difficult problem to connect reinforcing bars at construction joints that are not normally reserved. The upset straight thread connection not only solved the problem, speed up the construction progress, and the quality is stable, safety factor, but also save steel. Practice has proved that this is an ideal method of construction of steel joints.
