1.升降桿

　　如果(guo)地(di)板(ban)是預制板(ban)，則吊(diao)桿的(de)(de)(de)鋼鉤嵌入(ru)(ru)板(ban)的(de)(de)(de)裂縫中(zhong)，只有(you)吊(diao)桿的(de)(de)(de)上(shang)端(duan)穿過吊(diao)鉤的(de)(de)(de)孔。 當地(di)面澆鑄時，地(di)板(ban)底部應(ying)從嵌入(ru)(ru)部分的(de)(de)(de)位置松開，嵌入(ru)(ru)部分應(ying)用釘子(zi)固定在地(di)板(ban)下(xia)，然后吊(diao)桿的(de)(de)(de)上(shang)端(duan)可以彎曲(qu)并扭曲(qu)穿過 嵌入(ru)(ru)式部件(jian)上(shang)的(de)(de)(de)環孔。

　　2.安裝大龍骨

　　將大龍(long)骨(gu)(gu)(gu)放在狗的龍(long)骨(gu)(gu)(gu)上，將大龍(long)骨(gu)(gu)(gu)放上，讓吊桿的下(xia)端伸入大龍(long)骨(gu)(gu)(gu)垂直龍(long)骨(gu)(gu)(gu)的孔中，然后(hou)用螺母擰緊。 根據天花板中尖拱的高(gao)度，計(ji)算(suan)出大龍(long)骨(gu)(gu)(gu)各吊點的拱形(xing)值。 螺栓和螺母用于(yu)制作(zuo)大龍(long)骨(gu)(gu)(gu)的整(zheng)體拱形(xing)值。 調整(zheng)后(hou)，擰緊大龍(long)骨(gu)(gu)(gu)垂直吊架。

　　3.安裝龍骨

　　將(jiang)中(zhong)(zhong)龍(long)(long)骨(gu)(gu)(gu)吊件(jian)(jian)放在大(da)龍(long)(long)骨(gu)(gu)(gu)上，將(jiang)中(zhong)(zhong)龍(long)(long)骨(gu)(gu)(gu)固定在龍(long)(long)骨(gu)(gu)(gu)的垂直吊件(jian)(jian)上。 如果中(zhong)(zhong)間龍(long)(long)骨(gu)(gu)(gu)與橫(heng)梁相交，則中(zhong)(zhong)龍(long)(long)骨(gu)(gu)(gu)的平面(mian)接頭放置(zhi)在中(zhong)(zhong)間龍(long)(long)骨(gu)(gu)(gu)上，并且(qie)十字花鍵固定中(zhong)(zhong)龍(long)(long)骨(gu)(gu)(gu)的平面(mian)接頭。

　　4.龍骨安裝

　　將小龍(long)(long)(long)(long)骨懸掛件放(fang)在大龍(long)(long)(long)(long)骨上(shang)，并(bing)將小龍(long)(long)(long)(long)骨固定在小龍(long)(long)(long)(long)骨的垂直龍(long)(long)(long)(long)骨上(shang)。 如(ru)果龍(long)(long)(long)(long)骨與橫(heng)梁相交，則將龍(long)(long)(long)(long)骨的扁平(ping)接頭放(fang)置(zhi)在龍(long)(long)(long)(long)骨上(shang)，并(bing)且橫(heng)梁固定龍(long)(long)(long)(long)骨的平(ping)面接頭。

　　5.封面

　　安裝龍骨后，如果沒有問題，可以根(gen)據蓋子的材料用自攻螺釘或粘合劑固定蓋子。
