室内吊顶类构造做法 Indoor condole top class construction method 房屋顶棚是现代室内装饰处理的重要部位，其形式有悬吊式和直接式两种。 The roof of the house is the important part of modern interior decoration processing, its form has suspension type and direct type two kinds. 顶棚有两大系列处理，一是以金属材为骨架系列，一是以木龙骨为骨架体系。处理上可分为明架（骨架露出）及暗架（骨架隐藏）两种方式。 The ceiling has two series of processing, one is the metal frame series, one is the frame system of the wooden keel. The processing can be divided into two modes: the frame display and the frame hiding. 悬吊式顶棚由三部分组成：即吊杆或吊筋（镀锌铁丝、钢筋、螺栓、型钢、木方等）、龙骨（木质、轻钢、铝合金）及面层（各种抹灰、各种罩面板和装饰板材）。 Suspended ceiling is composed of three parts: the derrick or steel hanger (galvanized iron wire, steel bar, bolt, steel, wood square, etc.), keel (wood, light steel, aluminum alloy) and surface (all kinds of plaster, all kinds of cover panels and decorative plate). 1 吊顶龙骨构造做法 1 condole top keel construction method 1）U型轻钢吊顶龙骨构造 1) U type light steel suspended keel structure U型轻钢龙骨是以镀锌钢带、铝带、铝合金型材或薄壁冷轧退火黑铁皮卷带为原料，经冷弯或冲压而成的顶棚吊顶骨架支承材料。 U light steel keel is gelidunm.75ix.cn caomoju.75ix.cn liujiaohupo.75ix.cn gaiban.75ix.cn hupomoju.75ix.cn liushuicaoo.75ix.cngalvanized steel, aluminum, aluminum alloy profile or thin-walled annealing and black sheet roll as raw material, through the cold bending or stamping of ceiling ceiling framework bearing material. 结构：U型轻钢龙骨分为主龙骨（大龙骨）、次龙骨（中、小龙骨）及连接件三部分。 Structure: the steel keel of the U type is the main keel (the great keel), the subkeel (center, keelkeel) and the connecting parts three parts. 功能：主龙骨是轻钢龙骨体系中主要受力构件；次龙骨的主要功能是同饰面板固定；连接件是连接主、次龙骨，组成一个骨架的重要部件，一般配套使用。 Function: the master keel is the main force in the light steel keel system. The main function of the second keel is to be fixed with the decorative panel. The connecting piece is the important part that connects the main and the secondary keel to form a skeleton.
