Description
技术领域
本发明涉及悬吊式天花板系统,并且特别地涉及用于承载格栅龙骨的改进的支撑杆。
背景技术
支撑杆例如从美国专利7,578,107和8,898,986获知。这些专利中公开的产品可以用于悬吊主龙骨或T形件,使得减少吊线并且竖直地和水平地更均匀定位悬吊格栅。
典型地,支撑杆由规则间隔的结构产生,所述结构捕获格栅主龙骨的加强球头。支撑杆在其端部连接以跨越大于其单独的长度的距离。需要降低支撑杆的制造成本,对于给定重量增加其竖直和水平梁的强度,减小包装体积,提高操作能力,并且便于其安装。
发明内容
本发明提供了一种改进的金属片支撑杆及其制造方法。本发明的支撑杆包括在邻近上边缘的区域处的新颖的纵向延伸肋。除了竖直和侧向加强金属片支撑杆的主要功能之外,肋用于竖直地分度正安装到最后安装的支撑杆的端部的支撑杆的端部。通过将其端部搭接在一起并且通过滑动当前正在安装的支撑杆直到两个支撑杆中的预制螺纹孔至少部分地对准,可以将支撑杆快速且准确地彼此分度。驱动通过两个孔的尖头螺钉确保先前安装的和目前正在安装的支撑杆之间的准确、完全水平和竖直配准。
公开的加强肋另外用于将吊线引导到预制接收孔中,使得不需要吊线与吊孔的精确对准。
吊孔有利地相对于支撑杆的中心平面定位成使得支撑杆竖直地悬吊,由此使得更容易地实现格栅构件的随后组装并且具有更大的位置精度。用于接收格栅构件的结构优选地成比例以形成摩擦锁定配合,使得减小支撑杆和格栅龙骨之间相对滑动的风险。公开的肋构造与例如用于将格栅龙骨附接到壁挂角和通道的现有夹式硬件兼容。
支撑杆优选通过辊轧工艺由卷状金属片材制成以实现低制造成本。支撑杆具有相对于在片材的平面中并且在支撑杆的顶边缘和底边缘之间居中的纵向轴线的非对称截面,并且具有开槽的底边缘。该不对称和开槽边缘使辊轧成形有问题。本发明通过从普通金属片条以镜像关系同时辊轧成形一对支撑杆克服了该情况。一旦建立横截面,原料的条或带沿着其中心分开以产生两个支撑杆。

具体实施方式
图1-3示出了本发明的支撑杆的细节,所述支撑杆用于悬吊例如图8中所示的用于悬吊式天花板(由数字12标示)的主格栅龙骨。支撑杆是金属片体,优选地由例如.032英寸/.036英寸规格的G40热浸镀锌(HDG)原料辊轧成形。支撑杆的合适长度是1091/2英寸,但是也可以根据需要产生其它长度。所示的支撑杆具有2-1/8英寸的标称高度,但是可以提供其它高度。
具有矩形孔13的大体形状的格栅龙骨球头接合特征在支撑杆的下边缘14处以规则的间隔(例如以8英寸的间隔)重复。以矩形孔13为中心的槽17从孔通向边缘14。成角槽18离开铰接区域19以便于将左或右耳片21手动弯曲到支撑杆的平面之外。耳片21的这样的位移允许格栅龙骨球头22以侧向移动组装到孔13的区域中。弯曲耳片21其后弯曲回到支撑杆的平面中以将格栅龙骨球头22捕获在孔13中。孔13的下半部可以略窄一些以提供与球头22的侧壁的例如.005英寸的干涉。当由恢复的耳片21捕获时,支撑杆悬吊格栅龙骨11,并且当天花板完成时,悬吊天花板结构的任何关联的下面区域。
当支撑杆是如下面解释的附加支撑杆时,在支撑杆10中冲孔或以其它方式形成一组四个间隔的孔26(在矩形孔13(图2)的竖直中心线的每一侧上对称地布置两个)以便可选使用。在矩形孔13上方的中心和相邻的矩形孔之间的中间冲孔或以其它方式形成较大的孔27。
一系列纵向延伸的加强肋30形成于支撑杆10的上半部中。优选地,肋30具有V形横截面,平坦侧相对于彼此成直角并且相对于支撑杆的下半部31的平面成45度布置。在所示的布置中,支撑杆10两侧的肋30的顶峰具有离支撑杆的下半部31的平面相同的距离。在所示的示例中,峰间距离(图3的从左侧到右侧)标称为.29英寸。小孔26和较大孔27中的上部孔可以有利地在肋30中的一个的顶峰处的金属片中的折痕上居中。
图7A和7B示出了用于制造支撑杆10的辊轧成形工艺。金属片材36的条带由具有一对进给辊39的进给装置38从供给卷37进给。间歇地进给卷材37的进给装置或站38将片材输送到冲床41上,在该处从片材36逐渐冲出孔13、26、27和槽17、18。片材的储料器或下垂部分42在冲床41和辊组43之间建立。该部分42的长度周期性地变化以导致通过冲床41的间歇进给和通过辊组43建立的一致的线速度。在所示的示例中,支撑杆的轮廓在前八辊孔型中形成的。
由于在一个横向侧上的肋30和在另一横向侧上的槽17,支撑杆固有地难以辊轧成形。根据本发明,通过在原料36的单个条或带上同时形成两个支撑杆,克服了该困难。图4-6示出了该工艺的细节。图4示出了在冲床41中产生的孔13、26和27以及槽17、18。这些特征彼此布置为镜像,使得它们关于金属片条或带36的纵向中心线对称。
在辊轧成形站43中,条带的相对边缘区域形成有肋30,再次相对于条带的纵向中心线对称地布置。条带36在倒数第二个辊轧站被切开,并在最后一个辊轧站被重新成形。
具有与辊轧成形站中的原料36的线速度一致移动的刀片的移动切断装置45将条带36切割成支撑杆的长度。这包括从在两个支撑杆的后端和两个连续支撑杆的前端之间分开的条带切割2.5英寸的段。该段切断在图5的右侧示出。支撑杆可以堆叠在纸箱中,或者在切割站处切割成长度之后以其它方式准备好进行包装。对于给定的线速度,公开的装置和方法是由金属条带形成单个支撑杆的设备的生产的两倍。
图8示出了使用支撑杆10的悬吊式天花板的一个示例。典型地,支撑杆10位于4英尺中心上,并且按照惯例通过线48从顶部结构悬吊。参考图2和3,示出了吊线孔27的顶边缘优选位于支撑杆10的下半部的平面中或至少与其紧邻,使得支撑杆竖直地悬吊,使测量和天花板安装中的其它步骤更方便、准确、和快速。
在天花板12的周边,支撑杆可以使用通常用于锚固格栅龙骨的常规夹子49锚固到墙壁。在两个相对的肋30之间测量的支撑杆的宽度足够窄,以适合通常将接收格栅龙骨的加强球头的夹子。可以使用通常用于附接到格栅龙骨的加强球头的螺钉的夹子49中的预制孔51,以利用自钻螺钉52将夹子锚固到支撑杆。当使用钳子或其它合适的工具将耳片21中的一个手动地弯曲到支撑杆10的平面之外时,格栅龙骨53通过将其上部加强球头22定位在相应的孔13中而组装到支撑杆。在球头22接收在孔13中并且纵向适当定位的情况下,关联的耳片21被手动地弯曲回到其初始平面中。如上所述,孔13略小于球头22,使得格栅龙骨11摩擦锁定在适当位置。
如图8中所示,天花板12可以包括用于支撑格栅龙骨11的端部的壁通道56。可以在支撑杆位置的两侧局部地切割壁通道56的上凸缘57以与支撑杆的端部间隔。凸缘57的切断部分可以向上弯曲到竖直位置。夹子49可以组装在通道后面并用合适的螺钉固定到墙壁。
在天花板区域的跨度大于单个支撑杆的长度的情况下支撑杆的公开特征便于组装多个支撑杆。参考图5,可以理解的是,由于上面讨论的段切断,在两个支撑杆的端部搭接并且保持孔13之间的中心到中心距离的情况下,支撑杆的端部将不会干涉最后的孔13或这样的孔中的格栅龙骨。
肋30使搭接的支撑杆端部在竖直方向上自对中并且水平地引导端部直到一组孔26大致对准。在任何一对大致对准的孔中驱动的自攻螺钉将精确地使支撑杆一起配准,具有搭接的支撑杆10的孔13的期望的中心到中心的距离。
支撑杆的几何形状使其自身适合于包装的紧凑堆叠布置,原因是肋30彼此嵌套并且不会经历堆叠的侧向移动。而且,支撑杆的侧向刚度使多个支撑杆的包装比现有技术产品更易于操作。
尽管所示的悬吊式天花板面对附接到格栅龙骨11的下面的干墙板,但是应当理解的是,支撑杆容易与支撑隔音瓦的格栅龙骨一起使用。
显而易见本公开作为例子并且可以通过增加、修改或消除细节进行各种变化而不脱离本公开中包含的教导的合理范围。所以本发明不被限制到本公开的特定细节,除非以下权利要求必然这样被限制。
