Description

干墙板片末端接头
技术领域
本发明涉及干墙天花板构造，并且确切地说，涉及其中在干墙板片之间的粘接末端接头容易隐蔽的构造。
背景技术
干墙板片制造为矩形面板，其标准宽度为四英尺，且规则的系列长度为8、10、12、14和16英尺或公制的行业等效尺寸。板片的长边缘或边际在其正面是锥形的。提供锥形边际以使得带与接合剂能够接纳于正构造的天花板的正面平面上方的接头中。由于用以制作板片的生产工艺的限制，板片的末端不是锥形的。干墙板片的末端之间的接头，有时称为对接接头，是难以隐蔽的，因为接合带的厚度会侵入天花板正面的平面中。天花板中的对接接头特别难以隐蔽，部分原因是它们经常因间接照明而变得突出。干墙天花板经常大量地纹理化以掩盖对接接头的存在。在指定相对光滑表面和/或干墙具有源自多孔面的声学性质的情况下，天花板的纹理化是不实际的。
美国专利7,578,107和8,898,986说明可用于悬挂横向金属片干墙网格T形件的金属片条带或杆的实例。所述条带或杆沿着其长度具有规则的钥孔状狭槽，所述狭槽捕获T形件的上部加强球根状体。干墙板片常规地通过自钻孔螺钉附接到悬挂的网格T形件的下部凸缘面。
发明内容
本发明提供一种用于悬挂式干墙天花板的基于网格的结构，其促进了干墙对接接头的隐蔽。在发明的结构中，网格龙骨或T形件在平行规则隔开的中心上悬挂于水平平面中。干墙板片紧固到网格T形件的下部面。干墙板片被定位以使得其长度横向于网格龙骨且其对接末端在相邻网格龙骨之间中途悬置。平坦面的刚性桥部件位于相邻网格龙骨之间且上覆于干墙板片的对接末端。所述桥部件支撑于相邻龙骨的凸缘的顶部上，以使得其下部表面在龙骨凸缘的底部面的平面上方隔开凸缘的有效厚度。通常，凸缘在其纵向边缘上的折边处较厚。干墙板片末端螺旋连接到桥部件。
因为桥部件下部表面在龙骨凸缘的平面上方，所以致使干墙板片的末端局部向上弯曲一个精确距离，所述距离对应于龙骨凸缘的有效厚度。
干墙板片的末端的此弯曲具有形成伪锥形以接纳接合带和接合剂的效果。所述伪锥形适于完全接纳在干墙板片的主要面区域的平面上方的接合带和接合剂。锥形受到竖直和水平地限制以使得仅需要窄的一条接合剂来使接头平整。
本发明因此避免了条带和接合剂从干墙板片的主要面区域的平面突出的对接接头。本发明特别有用于例如美国专利8,684,134、8,770,345和8,925,677中所公开的声学干墙天花板。通常，使用重纹理涂层来隐蔽突出的粘接对接接头。此方法对于声学天花板是不实际的，因为此类涂层将阻挡干墙板片中的声音吸收孔口，且减少或消除声学性质。
附图说明
图1是悬挂式干墙天花板的对接接头的片段横截面图，是在图3中的1-1处指示的竖直平面中截取；
图2是图1的对接接头的放大比例的视图；以及
图3是体现本发明的悬挂式天花板的片段示意性平面图。
具体实施方式
悬挂式天花板10包含附接到网格龙骨12的矩形干墙板片或面板11。如常规那样，干墙板片11是基于石膏的，且通常是4英尺宽乘8、10、12、14或16英尺长且3/8、1/2或5/8英寸厚。本公开中所述的尺寸既定包含行业公制的等效尺寸。通常，板片11的长边缘是锥形的，用于当板片沿着其长边缘对接时接纳接合剂和接合带。
图示的网格龙骨12是T样式的，具有上部加强球根状体16、下部凸缘17以及球根状体与凸缘之间的竖直腹板18。网格龙骨或T形件12可由单个细长条的金属片辊轧形成，通常为此项技术中已知的G40热浸镀锌钢。
通过使用行业中已知的金属片吊杆以及从例如美国专利7,578,107和8,898,986中获得比较平坦的天花板构造。通过线22悬挂于共同水平平面中的杆21在垂直于随后竖立的T形件12的方向上在例如4英尺中心上以平行的行相互隔开。杆21相对于彼此端部定位，以使得它们呈现相互对准的矩形孔23以用于捕获加强球根状体16，用于T形件12的竖直顶部支撑。
图3示意性地图示了在16英寸中心上的4英尺乘8英尺干墙板片11和网格T形件12的布局的实例，后者由支撑杆或吊杆21中的孔23的规则间距确定。如指示，板片11被布置成其长度方向与T形件12的纵向方向垂直或交叉。板片11进一步被布置以使得其末端26是悬臂式且在与邻近网格T形件12中途隔开的位置处对接。
板片11通过自钻孔螺钉28附接到网格T形件12的下部面27，所述自钻孔螺钉如常规那样穿透板片和T形件凸缘两者。检查图2示出了网格T形件凸缘17的纵向边缘向上折叠成中空折边29，这增加了跨越凸缘元件的底部到顶部竖直测得的凸缘有效厚度。举例来说但非限制，所述有效厚度可优选地在约0.50英寸到约0.55英寸之间。
呈平坦矩形刚性板形式的桥元件31位于网格空间中，上覆于两个干墙板片11的对接末端26。图示的桥31是平板，其标称平面尺寸为4英尺乘15-7/8英寸且厚度为5/8英寸。优选地，宽度尺寸大于相邻凸缘17之间的间隙，以使得板31一旦定位便不容易从凸缘17落下。板31比常规干墙板片基本上更具刚性(至少两倍刚性)。优选地在首先通过螺钉28将板片紧固到邻近的T形件12之后，通过合适的螺钉28将板片11的对接末端26上拉到桥板31的底表面。以此方式，干墙板片11的末端向上弯曲一个精确距离，所述距离接近T形件凸缘17的有效厚度。效果是在干墙板末端26上提供伪锥形。在对接的板片末端26两者上的此伪锥形形成了具有有限但充分竖直尺寸的空间，用于完全接纳在干墙板片11的主要非锥形面区域的平面上方的接合带和接合剂。这使板片11能够以平坦度进行粘接，这使得当涂漆时不易察觉对接末端接头而无显著纹理。接合带通常为约.006英寸至.009英寸厚且2英寸宽。所述板具有足够刚性以当旋拧于其上时上拉干墙末端，以使得从对接接头边缘向内1-1/2英寸的伪锥形升高至少.009英寸。合适的板产品是由美国Gypsum公司出售的5/8英寸Aqua-ToughTM内面板。
所公开的发明性悬挂布置特别适合与声学干墙产品一起使用，例如前述美国专利中所公开。如这些专利中所公开，干墙板片通过正面和背面纸覆盖物在整个其主要区域穿孔，且正面覆盖物又覆盖有非编织可渗透纱布。最终涂刷所述纱布以隐蔽孔，同时维持足够孔隙度以允许空气通过且因此声音传输到穿孔中。本发明的布置使声学干墙板片的对接接头能够容易粘接和完成，而不需要重的和/或纹理化外观涂层来隐蔽接头。
应显而易见的是，本公开是借助于实例，并且可以通过在不脱离本公开中所含有的传授内容的合理范围的情况下添加、修改或消除细节来进行各种变化。因此，本发明不限于本公开的特定细节，除非所附权利要求书必要地如此限定。
