無梁拱(太空瓦)有哪些好(hao)處(chu)?
無梁拱(太空瓦)結構的好處不僅僅體現(xian)在跨度大、成本(ben)低、施工快這三(san)點上(shang)
今(jin)天(tian)帶大家(jia)深(shen)入(ru)認識一下金(jin)屬拱形波(bo)紋鋼(gang)屋蓋(gai)結構(gou)的好處(chu)。
無梁(liang)拱(太空(kong)瓦)的具體型號為914-610(拱形屋頂(ding)被廣泛用于工(gong)業(ye)廠(chang)房、倉儲庫房、體育(yu)場館、集貿市場、車庫機(ji)庫等(deng)，它無梁(liang)無擦、空(kong)間高(gao)大開(kai)闊，可以隨意分割組合(he)，使用方便，自(zi)重輕、剛性強、彈性好、抗震性能優越(yue)等(deng)特(te)點。
MIC240/120拱(gong)(gong)(gong)形屋面還(huan)具有(you)承壓效果，拱(gong)(gong)(gong)所(suo)承受的(de)(de)荷載(zai)不同(tong)，其(qi)壓力曲線的(de)(de)線形也不相同(tong)，一般按恒(heng)載(zai)下(xia)壓力曲線確定;在活載(zai)作用(yong)(yong)下(xia)，拱(gong)(gong)(gong)內(nei)力可能產生彎(wan)矩，這時體現出金(jin)屬波紋(wen)鋼屋蓋的(de)(de)好處：鉸(jiao)的(de)(de)設置(zhi)就(jiu)會影(ying)響拱(gong)(gong)(gong)內(nei)彎(wan)矩的(de)(de)分布狀況。與剛架(jia)相仿，只有(you)地基良好或兩側(ce)拱(gong)(gong)(gong)肢處有(you)穩(wen)定邊跨結(jie)構時才(cai)采用(yong)(yong)無鉸(jiao)拱(gong)(gong)(gong)，這種拱(gong)(gong)(gong)很少用(yong)(yong)于(yu)房(fang)屋建筑。雙鉸(jiao)拱(gong)(gong)(gong)應(ying)用(yong)(yong)較(jiao)多，為適應(ying)軟弱地基上支座沉降差(cha)及拱(gong)(gong)(gong)拉桿變(bian)形，最好采用(yong)(yong)靜定結(jie)構的(de)(de)三鉸(jiao)拱(gong)(gong)(gong)。
