承重梁構造

1，承(cheng)重(zhong)梁(liang)選用歐式(shi)古(gu)典箱(xiang)型梁(liang)組(zu)織設計方案，重(zhong)量輕，合理配置；

2，整個PCB線路板制做，無對(dui)接焊縫，比拼湊承重梁(liang)更牢(lao)固。

3，豎(shu)直剛度為(wei)1/800，梁(liang)端拱度由數控切割整個(ge)PCB線路(lu)板開料，精(jing)準度高(gao)。

4，選用埋弧焊自動焊、無損(sun)檢測。焊后總體拋丸除銹，消地(di)應(ying)力(li)、防銹處理(li)，超過Sa2.5級；

5，厚(hou)鋼板原材料為Q235B；環氧富鋅漆，薄(bo)厚(hou)120μm。

端梁一部分
