無(wu)梁拱(太空瓦)的具體型(xing)號為(wei)914-610(拱形屋頂被廣(guang)泛用于工(gong)業廠房、倉儲(chu)庫(ku)房、體育場館、集貿(mao)市場、車庫(ku)機庫(ku)等，它(ta)無(wu)梁無(wu)擦(ca)、空間(jian)高大開(kai)闊，可(ke)以隨(sui)意(yi)分割組合，使用方(fang)便，自重(zhong)輕、剛性(xing)強、彈性(xing)好、抗(kang)震性(xing)能優越等特點。
拱(gong)(gong)(gong)形(xing)屋面還具(ju)有(you)承壓效果，拱(gong)(gong)(gong)所(suo)承受(shou)的(de)(de)荷載(zai)不同，其壓力曲線的(de)(de)線形(xing)也(ye)不相同，一(yi)般(ban)按恒載(zai)下壓力曲線確(que)定;在活載(zai)作用下，拱(gong)(gong)(gong)內力可能(neng)產生彎矩，這時體(ti)現出金屬(shu)波紋鋼屋蓋的(de)(de)好處(chu)：鉸的(de)(de)設置就(jiu)會影響拱(gong)(gong)(gong)內彎矩的(de)(de)分布狀況。與(yu)剛架相仿(fang)，只有(you)地基良好或兩側拱(gong)(gong)(gong)肢處(chu)有(you)穩(wen)定邊(bian)跨結(jie)構(gou)時才采用無(wu)鉸拱(gong)(gong)(gong)，這種(zhong)拱(gong)(gong)(gong)很少用于房屋建筑(zhu)。雙鉸拱(gong)(gong)(gong)應(ying)用較多，為適應(ying)軟弱(ruo)地基上支座沉(chen)降差及拱(gong)(gong)(gong)拉桿變形(xing)，最好采用靜定結(jie)構(gou)的(de)(de)三鉸拱(gong)(gong)(gong)。
