⑵無梁拱(gong)金屬波紋(wen)鋼屋(wu)蓋局部改變拱(gong)高，拱(gong)高變化處(chu)(chu)(chu)的(de)豎立面(mian)用(yong)工業(ye)建(jian)筑金屬波紋(wen)拱(gong)形采(cai)光(guang)板(ban)封閉。罩(zhao)棚屋(wu)頂(ding)(ding)采(cai)光(guang)出處(chu)(chu)(chu)的(de)開(kai)口(kou)不預(yu)留(liu)，待罩(zhao)棚屋(wu)頂(ding)(ding)結(jie)構(gou)完成后(hou)(hou)，用(yong)等離(li)子切(qie)割機雜一結(jie)構(gou)上開(kai)孔(kong)。罩(zhao)棚屋(wu)頂(ding)(ding)采(cai)光(guang)板(ban)安裝(zhuang)完畢后(hou)(hou)，開(kai)孔(kong)處(chu)(chu)(chu)用(yong)密封膠封閉。采(cai)光(guang)處(chu)(chu)(chu)結(jie)構(gou)要加強。
