安裝主輕鋼龍骨

1)主龍骨應吊掛在吊桿上。主龍骨間距900～1000mm。主龍骨分為蘭州輕鋼龍骨和(he)T 形(xing)龍(long)(long)(long)骨。輕(qing)鋼龍(long)(long)(long)骨可選用UC50 中龍(long)(long)(long)骨和(he)UC38 小龍(long)(long)(long)骨。主(zhu)龍(long)(long)(long)骨應平(ping)行房間長向(xiang)安裝，同時應起拱，起拱高度為房間跨度的(de)1/200～1/300。主(zhu)龍(long)(long)(long)骨的(de)懸臂(bei)段不應大于(yu)300mm，否則(ze)應增加吊桿(gan)。主(zhu)龍(long)(long)(long)骨的(de)接長應采取對接，相鄰(lin)龍(long)(long)(long)骨的(de)對接接頭要相互(hu)錯開(kai)。主(zhu)龍(long)(long)(long)骨掛好后應基本(ben)調平(ping)。

2)跨度大于(yu)15m 以上的吊(diao)頂，應在主龍(long)骨上，每隔15m 加一(yi)道大龍(long)骨，并垂(chui)直主龍(long)骨焊接牢固。

V型吊掛式龍骨安裝注意

1、用于(yu)吊頂時(shi)，石膏(gao)板(ban)的長邊必須(xu)(xu)與(yu)副龍骨成垂直(zhi)或平各市地鋪(pu)設，固定(ding)件(自攻螺絲)與(yu)石膏(gao)板(ban)的距離約10-16mm，緊(jin)固時(shi)，石膏(gao)板(ban)必須(xu)(xu)與(yu)骨架訂(ding)牢;

2、固定板材時，應從(cong)一(yi)塊(kuai)板的(de)中部各長(chang)邊(bian)及(ji)短邊(bian)固定，釘子定位后，釘頭(tou)略埋入板內，但不得損(sun)壞(huai)板面;

3、石(shi)膏板(ban)對(dui)接時要靠緊，接縫處必須加橫撐(cheng)龍骨，石(shi)膏板(ban)應(ying)在(zai)無應(ying)力狀態下安裝，不得強(qiang)壓定位，應(ying)確保副龍骨的底面處于同一(yi)平(ping)面，龍骨接長(chang)的接插(cha)部位應(ying)錯開(kai)。
