Description

开放式梁腹格栅龙骨
技术领域
本发明涉及悬吊式天花板格栅结构。
背景技术
悬吊式天花板典型地包括在其上支撑有天花板贴砖或干式墙面板的矩形金属格栅。商业建筑行业是高度竞争性的并且因此该领域的建筑物材料的成本是重要的。原材料的消耗,特别是没有大的再循环含量的材料的消耗,同样是环境保护所关注的。因此,对于消耗更少的材料并且可以经济地生产的悬吊式格栅产品存在着需求。
发明内容
本发明提供了一种用于悬吊式天花板的格栅龙骨,该格栅龙骨具有减小的材料含量并且潜在地具有改善的抗扭强度。本发明的格栅龙骨采用具有开放式梁腹的平行弦杆桁架的形式。该梁腹由处于与潜在的副龙骨位置相对应的规则地间隔开的位置处的板构成,并且在其它地方是开放的。弦杆可以具有与已知的格栅T形件轮廓相对应的横截面。上部弦杆可以包括例如矩形的空心框横截面,并且下部弦杆可以包括类似的空心盒形截面以及相关的凸缘部段、或者可以采用简单的T形状的形式。
在一个公开实施例中,梁腹板被接收在形成弦杆的金属条的折叠的边界或边缘部段之间。板和弦杆条的边界部段通过例如整体缝合而固定在一起。
在另一公开实施例中,弦杆条的边界部段被直接搭接在一起并且在与期望的板位置相对应的纵向间隔开的区域处被共同切缝。梁腹板被配置成接收在切缝中。切缝在接收梁腹板之后被紧紧地挤压以便将板和弦杆永久地固定在一起。
本发明在选择顶部和底部弦杆以及梁腹板中所使用的材料方面提供了高度的灵活性。这些部件可以由不同的材料、规格和品质制成。通常,部件由诸如钢或铝的金属制成。梁腹可以由诸如合适的塑料的非导电材料制成使得弦杆是彼此电绝缘的。
本发明根据需要使形成下部弦杆的条能够形成封闭盒形截面,该截面可以潜在地增大格栅构件的抗扭强度。

具体实施方式
图1-3示出根据本发明构造的格栅龙骨10的第一实施例。格栅龙骨10是长形构件,如图3中所示,它具有倒置T形件的横截面,很像熟悉本领域的人员已知的常规的公知技术的格栅T形件。格栅构件10包括平行的上部和下部弦杆,分别为11、12,以及纵向间隔开的梁腹板13。
弦杆11、12优选的是由金属板条(典型地是热浸渍的镀锌钢)滚轧成形的。板13可以具有与弦杆相同的材料。在所示的实施例中,弦杆11、12各自关于图3中表示为14的假想竖直平面是对称的。优选的是,弦杆11、12各自是由单个的金属条形成的。上部弦杆11具有空心盒形截面16以及两个悬垂的裙边,裙边是由延伸至纵向边缘18的弦杆条的边界部段17形成的。
下部弦杆12是滚轧而成的或者以其它方式被制造,具有下部水平凸缘面21,并且在该凸缘面的远侧边缘23处被折回其自身上以便提供双层的凸缘部段22。最后,在格栅构件或龙骨10被组装在悬吊式矩形格栅中之后,凸缘部段或部分22以常规的方式来支撑放入的天花板贴砖或干式墙板。在远侧凸缘边缘23与平面14之间,下部弦杆条被向上折叠或弯折而形成盒形截面25的侧边24并且再折叠或弯折以形成该盒形截面的顶边26。相邻中心平面14处,下部弦杆条被向上折叠从而形成直立的边界部段27,该边界部段在纵向边缘28处终止。
所示的梁腹板13具有在宽度方向上居中定位的、竖直取向的通槽31,用于按本领域公知的方式来接收副龙骨连接件。梁腹板13在龙骨10的纵向上彼此间隔开距离,该距离优选地基本上大于板的宽度。例如,在所示的实施例中,格栅龙骨10为2”高,板位于6”的中心上,并且板为大约1”宽。这种中心到中心的间距是理想的,原因是它在组装格栅时在适当的位置处提供副龙骨槽缝。
当格栅龙骨10将要与天花板贴砖一起使用时,下部弦杆12的条或本体可以在从下方可见的侧面上被粉刷。当格栅龙骨将用于支撑干式墙天花板时,条的粉刷可以省略。弦杆11和12的本体条可以具有相同或相似的规格或厚度。在由热浸渍的镀锌钢制成的一个例子中,上部弦杆11具有.012”的规格,下部弦杆12具有.014”的规格,而板13具有.016”的规格。
梁腹板13可以在将弦杆滚轧成形时与弦杆11和12组装在一起。板13布置在上部和下部弦杆11、12的边界部段17、27之间。板13的高度可以被限制为使得板的顶部和底部均不延伸进入上部和下部弦杆11、12的空心区域中。
在所示的结构中,板13是通过整体的缝合部位36而在弦杆11、12上机械地固定就位。优选地,两个或更多个缝合部位固定板13的顶部和底部,但是在顶部或底部上应该存在至少两个缝合部位并且在板的相对端部应该存在一个缝合部位。缝合部位可以是任何类型的,其中穿过弦杆条与板的三个接触层对材料块进行切缝,并且将切缝后的材料在其平面的各方向上扩展并且此后朝切缝的材料的原始平面挤压回去。在美国专利6,047,511和5,979,055中公开了形成缝合部位的其它适当的方式。
如图所示,缝合部位36可以制造在弦杆条边界部段17、27上、在插入梁腹板13的位置处。除了用于将板13固定到弦杆11、12的主要目的之外,缝合部位增大格栅龙骨10的扭转刚度。
相对于格栅龙骨10的高度而言,梁腹13的宽的间距获得了显著的材料节约,与常规的格栅龙骨结构相比多达大约25%的材料节约。如前面所述,梁腹板的中心到中心的间距13可以为6”,并且格栅龙骨可以按48”的跨度得到充分的支撑使得梁腹板布置在设计跨度的1/8那么大的中心上,由此在梁腹板之间留下大的开放区域。典型地,主格栅龙骨10将以标称的12’长度进行制造。使用本领域已知的具有一体的或者分离的端部连接件的板39来将相同的格栅龙骨进行端到端的连接。
现在参见图4-7,示出根据本发明构造的开放式梁腹格栅龙骨41的另一形式。格栅龙骨41具有通过梁腹板44连接的上部和下部弦杆42、43。弦杆42、43优选地由金属板条滚轧成形,并且像图1-3的实施例一样可以是例如具有.014或.016规格的热浸渍的镀锌钢。板44可以具有相同或相似的材料和规格。
在其顶部和底部,板44被分为三个通过插入切割线而分隔的竖直延伸的接片46、47。中心接片47与板44的主体的平面偏离并且平行。在相对的外部接片46之间在板44中形成一对压印的肋48,以便加固板。
对于每个预期的板位置,上部和下部弦杆42、43各自被形成有两个纵向间隔开的切缝51。每个切缝51是穿过形成相应的上部和下部弦杆的片材或主体的相应的双边界部段52、53而切出的。切缝51在弦杆42、43的纵向方向上的长度足以接收其中一个外部接片46。通过将外部接片46定位在相应的切缝或凹穴51中来将板44与弦杆42、43进行组装。中心接片47的平面的偏移足够允许弦杆42、43的双边界部段52、53配合在接片46、47的相对面56、57的平面之间的空间中。
板44具有副T形件槽缝49和孔50以用于接收悬吊线。通过将切缝51紧紧压在外部接片46上并且将内部接片47紧紧压在弦杆42、43的边界部段52、53上,将板44机械地固定或锁定到弦杆42、43。
图9示意性地示出通过格栅龙骨的开放式梁腹结构提供的独特优点。与主龙骨63横向相交的一对格栅龙骨61、62被示出在相交的龙骨63的梁腹板64之间的位置处端到端地连接。将横向副龙骨61、62定位在梁腹板64之间任何期望的地方并且将其端到端地相连的能力在悬吊式干式墙系统中是有用的,其中干式墙面板的接头并不与梁腹64的中心对准。
图8示出本发明的格栅龙骨66的第三实施例。格栅龙骨66具有上部和下部弦杆67、68,它们可以与图1-3的实施例中所示的相同。在第三实施例中,梁腹板69足够长而能提供两个副龙骨连接件接收槽缝71,其中槽缝例如在6”的中心上。板69沿弦杆67、68的长度相互间隔较大的距离,例如间隔5”。可以通过结合图1-3的实施例所述的缝合过程来将板69固定到弦杆66、67。板69的布置减少了构造格栅龙骨66所需要的板的数量,而同时仍然提供可观的材料节约。
尽管本发明已经针对其特定实施例进行了显示和描述,但是这只是出于举例说明的目的而非限制的目的,并且本领域的技术人员将显而易见,在本文中显示和描述的具体实施例中的其它变化和修改全部属于本发明的预期精神和范围内。因此,本专利在范围和作用上既不局限于在本文中显示和描述的具体实施例、也不会以与本领域中已经由本发明促进的进步所达到的范围不相一致的任何其它方式受到限制。例如,将理解的是,不同于简单的矩形,梁腹板可以具有其它的多边形形状,并且梁腹板可以通过其它的技术、例如通过焊接、粘合剂或单独的紧固件而固定到相应的弦杆。
