無梁拱的采光主(zhu)要有兩種作(zuo)法(fa)：
⑴無梁拱在拱(gong)形屋(wu)頂(ding)槽板的殼板上開口，代之以(yi)金屬波紋(wen)拱(gong)形采光板。
⑵無梁拱(gong)金屬(shu)波紋鋼(gang)屋(wu)蓋局部改(gai)變拱(gong)高，拱(gong)高變化處(chu)的豎立面用(yong)(yong)工(gong)業建筑金屬(shu)波紋拱(gong)形(xing)采(cai)(cai)光(guang)(guang)板封(feng)(feng)閉。罩棚屋(wu)頂(ding)(ding)采(cai)(cai)光(guang)(guang)出處(chu)的開口不預留，待罩棚屋(wu)頂(ding)(ding)結構(gou)完成(cheng)后(hou)，用(yong)(yong)等離子切(qie)割機雜一(yi)結構(gou)上開孔。罩棚屋(wu)頂(ding)(ding)采(cai)(cai)光(guang)(guang)板安裝完畢后(hou)，開孔處(chu)用(yong)(yong)密封(feng)(feng)膠封(feng)(feng)閉。采(cai)(cai)光(guang)(guang)處(chu)結構(gou)要加強。
