在裝修的過程中，吊頂是不可缺少的。 龍骨是吊頂所現需要的材料，它一般分為木龍骨和蘭州輕鋼龍骨。使用木龍骨要注意木材要干燥。由于木龍骨的強度低，使用年限短，因此正逐步被蘭州輕鋼龍骨所取(qu)代。現在家庭裝修大部分選用不易變(bian)形、具有防火性能的蘭州輕(qing)鋼龍(long)骨。    

一、分類  1、蘭州輕鋼龍骨一般分為墻(qiang)體龍(long)骨(gu)(Q)和吊頂龍(long)骨(gu)(D)兩大類，  墻(qiang)體龍(long)骨(gu)主要(yao)規格分為Q50、Q75、Q100和Q150。  吊頂龍(long)骨(gu)主要(yao)規格分為D38、D50和D60等。  2、形狀分為U型(xing)、C型(xing)、T型(xing)、H型(xing)、V型(xing)、L型(xing)、CH型(xing)七種。     

二、看蘭州輕鋼(gang)龍(long)(long)骨(gu)(gu)(gu)(gu)的(de)規格(ge)型號和壁厚(hou)是(shi)否(fou)符(fu)合要求  1、墻(qiang)體龍(long)(long)骨(gu)(gu)(gu)(gu)的(de)厚(hou)度(du)(du)一般(ban)在0.6mm-1.0mm，  U型、C型和V型，承(cheng)載(zai)龍(long)(long)骨(gu)(gu)(gu)(gu)厚(hou)度(du)(du)一般(ban)在0.8mm-1.2mm，覆面龍(long)(long)骨(gu)(gu)(gu)(gu)的(de)厚(hou)度(du)(du)一般(ban)為0.5mm-0.6mm，  2、T型龍(long)(long)骨(gu)(gu)(gu)(gu)的(de)主、次龍(long)(long)骨(gu)(gu)(gu)(gu)其厚(hou)度(du)(du)均為0.27mm。承(cheng)載(zai)龍(long)(long)骨(gu)(gu)(gu)(gu)好不(bu)低于(yu)(yu)1.0mm，覆面龍(long)(long)骨(gu)(gu)(gu)(gu)好不(bu)低于(yu)(yu)0.5mm，T型龍(long)(long)骨(gu)(gu)(gu)(gu)好不(bu)低于(yu)(yu)0.27mm，墻(qiang)體龍(long)(long)骨(gu)(gu)(gu)(gu)好不(bu)低于(yu)(yu)0.6mm。偏(pian)薄的(de)龍(long)(long)骨(gu)(gu)(gu)(gu)容易力學性能(neng)不(bu)合格(ge)，有(you)些(xie)龍(long)(long)骨(gu)(gu)(gu)(gu)雖然(ran)力學性能(neng)合格(ge)，但容易引起(qi)變形(xing)。
