摘要
河南广播电视发射塔外塔柱采用10根巨型桉叶糖形钢管柱,桉叶糖管体两两交叉形成了5层巨大的构件,称之为X形节点。桉叶糖X形节点结构形式庞大,连接形式复杂且质量大,是本工程中最重要的连接和受力构件。对外塔柱X节点的组装、分体、焊接、检验等施工工艺进行详细阐述。通过X形节点胎架的制作、空间位置的定位、胎架精度的控制、焊接残余应力变形控制等一系列措施,成功地完成了桉叶糖管的压制与X形节点的制作。
The external columns of He＇nan TV Tower took the shape of huge throat smoothing candies.The tubes intersect with each other and form five-storey high huge X-shaped component.The X-shaped joints have huge volumes with complex connection details and they are also the most important load bearing members of this project.This paper introduced the assembly,division,welding and checking of the X-shaped joint in detail.Through the jig fabrication of the X-shaped joint,positioning of the spatial locations,the control of jig accuracy,control of the welding residual stress and deformation,the rolling of the throat smoothing candy-shaped tubes and the fabrication of X-shaped joints were successfully completed.
