矩形墩粗钢筋采用滚压直螺纹套筒连接技术

摘要

以矩形墩粗钢筋连接技术为例，从工艺原理、施工工艺等方面介绍了滚压直螺纹套筒连接技术，实践证明采用滚压直螺纹套简连接比传统搭接方法节约材料，提高了工效，该技术值得在工程施工中推广应用。%Taking the steel connecting technology of rectangle pile as an example, the paper introducing straight rolling screw sleeve connecting technology from aspects of technological principles and construction technology. Practice proves that straight rolling screw sleeve connecting method can save materials and improve construction efficiency comparing to traditional connecting method. Thus, the technology is worth promo- ting and application in engineering construction.
