    • A grid ceiling comprising a set of first parallel channel section elongate members and a set of second parallel channel section elongate members, the first members being so arranged transverse to the second members as to form a grid with polygonal spaces therein. Each channel shaped member includes a lower portion and two spaced side flanges extending upwardly therefrom. At least one integral hook is formed at each of the ends of the second members and co-operating first openings are formed in at least one side flange of the first members at first position situated at regular, spaced intervals therealong, so that the hooks of the second members can be engaged in said first openings to form said grid ceiling. A series of one or more second openings are formed in at least one side flange of the second member at second position situated at regular, spaced intervals therealong. The second openings are so shaped that, when the second members are cut at the relevant second positions transverse to the length of the second members, at least one of said integral hooks is formed.
    • 一种格栅天花板,包括一组第一平行通道段细长构件和一组第二平行通道段细长构件,第一构件横向于第二构件布置成在其中形成具有多边形空间的格栅。 每个通道形状构件包括从其向上延伸的下部和两个间隔开的侧边缘。 在第二构件的每个端部处形成至少一个整体钩,并且在第一位置处的第一位置的至少一个侧凸缘中形成有协同操作的第一开口,所述第一位置以其间隔规则间隔设置,使得钩 第二构件可以接合在所述第一开口中以形成所述格栅顶板。 一系列一个或多个第二开口形成在位于第二位置的第二位置的至少一个侧凸缘中,该第二位置沿着其间隔开间隔开。 第二开口的形状使得当第二构件在与第二构件的长度相交的相关的第二位置处被切割时,形成至少一个所述整体钩。
