框架结构工程中 ,框架梁的上部角筋、贯通筋常须用焊接的方式在现场连接。采用“窄焊”方法焊接时 ,由于模具的外形尺寸较大 ,安装不方便 ,速度较慢还影响其它工序的正常施工。我们针对以上问题 ,对“窄焊”模具做了如下改进 :将模具的主体托架部分及夹紧装置全部去掉 ,仅留下
In the frame structure engineering, the upper ribs and ribs of the frame beam must be connected in the field by means of welding. When using the “narrow welding” method for welding, due to the large size of the mold, the installation is inconvenient, and the slower speed also affects the normal construction of other processes. For the above problems, we have made the following improvements to the “narrow welding” mold: remove the main body bracket part of the mold and the clamping device, leaving only
