無梁拱(太空瓦)有(you)哪(na)些(xie)好處?
無梁拱(太空(kong)瓦)結構的好處不僅(jin)僅(jin)體現在跨度大、成本低、施工(gong)快這(zhe)三點上
今天帶大(da)家(jia)深入認識一下金(jin)屬拱(gong)形波紋鋼(gang)屋蓋結(jie)構的(de)好處(chu)。
無(wu)梁(liang)拱(太空瓦)的(de)具體型號為914-610(拱形屋頂被廣(guang)泛用(yong)于工業廠房(fang)、倉儲(chu)庫(ku)房(fang)、體育場館、集貿市場、車庫(ku)機庫(ku)等，它無(wu)梁(liang)無(wu)擦、空間高大開闊，可以隨意分割(ge)組合(he)，使用(yong)方便(bian)，自重輕、剛性強(qiang)、彈性好、抗震(zhen)性能優越等特點。
MIC240/120拱(gong)(gong)形(xing)屋(wu)面還具有承(cheng)(cheng)壓效果，拱(gong)(gong)所承(cheng)(cheng)受的荷載不(bu)(bu)同(tong)(tong)，其壓力曲線(xian)的線(xian)形(xing)也不(bu)(bu)相同(tong)(tong)，一般按(an)恒載下(xia)壓力曲線(xian)確定(ding)(ding);在(zai)活(huo)載作用(yong)下(xia)，拱(gong)(gong)內力可能產生彎(wan)矩，這時體現(xian)出金屬波紋鋼屋(wu)蓋的好(hao)處：鉸(jiao)的設置就會(hui)影(ying)響拱(gong)(gong)內彎(wan)矩的分(fen)布(bu)狀況(kuang)。與剛架相仿，只有地基良好(hao)或兩側(ce)拱(gong)(gong)肢處有穩定(ding)(ding)邊跨結構(gou)時才采用(yong)無鉸(jiao)拱(gong)(gong)，這種拱(gong)(gong)很少(shao)用(yong)于房屋(wu)建筑。雙(shuang)鉸(jiao)拱(gong)(gong)應用(yong)較多，為(wei)適(shi)應軟弱地基上(shang)支(zhi)座沉降差及拱(gong)(gong)拉桿變形(xing)，最(zui)好(hao)采用(yong)靜定(ding)(ding)結構(gou)的三鉸(jiao)拱(gong)(gong)。
