Abstract
本发明提供一种用于悬吊式天花板格栅的辊轧成型的金属片格栅龙骨、及其制造方法，该格栅龙骨具有由龙骨轮廓的中心腹板冲压出的限位突舌，所述突舌在可靠地定位天花板面板方面是有效的，并且在格栅龙骨与其它相同的龙骨嵌套在包装中时避免可见表面受损。
Description
技术领域
本发明涉及悬吊式天花板，并且具体而言，涉及格栅龙骨的改进。
背景技术
悬吊式天花板格栅以各种横截面制造以用于不同的功能并且/或者提供不同的外观。为了配送而包装这些格栅龙骨可能涉及在将交错的龙骨翻转的情况下将格栅龙骨并排嵌套。这种布置能够使龙骨被包装在其中的盒的尺寸以及在龙骨的运输和储存期间所占用的空间最小。尽管可以通过嵌套的龙骨组来节省空间，但是龙骨横截面的几何形状可能使在最终安装中可见的龙骨元件受损。运输和/或处理期间的振动能够造成相邻的龙骨的部件损坏龙骨的可见区域。
美国专利4,679,375显示了形成为具有由腹板冲压出的突舌的格栅T形件。突舌旨在使砖或面板在格栅空间中居中。突舌降低面板可能在悬吊式格栅空间中移位以及从凸缘滑落的风险。然而，这些现有技术的突舌在限制金属或塑料片的相对较薄的面板以及使所述金属或塑料片的相对较薄的面板居中方面是低效的。
发明内容
本发明涉及具有改进的限位突舌构造的格栅龙骨。由格栅龙骨的中心腹板冲压出的发明性的突舌能够保护嵌套的格栅龙骨不在运输过程中受损。一旦格栅龙骨被安装，突舌还能够将甚至相对较薄的天花板砖限制在格栅空间中并且使所述相对较薄的天花板砖在格栅空间中居中。
限位突舌特别适于结合到双显示类型格栅龙骨中。该龙骨类型具有阶梯形凸缘，该阶梯形凸缘尤其易于在紧凑地嵌套在包装或盒中时受损。
限位突舌能够更加易于在格栅轮廓由两个单独的辊轧成型操作制成的某些类型的格栅龙骨构造中并且当在这些辊轧成型操作之间执行冲压时实施。在这种龙骨构造中，邻近腹板的下部边缘的金属片区域可以不在预制件状态下折叠，使得存在加工间隙，用于在最终凸缘的水平面处传统地冲压突舌。将突舌定位在凸缘水平面保证甚至薄面板能够被限制在格栅空间的中心处。

具体实施方式
图4和5示出了用于形成用于悬吊式天花板的格栅的细长格栅龙骨10。图示的格栅龙骨10属于有时被称为双显示轮廓的类型。轮廓的特征在于两个水平凸缘11。凸缘11的中心部分12下降到凸缘的侧向向外部分13之下。格栅龙骨还包括位于凸缘11之上的中心竖直延伸的腹板14以及位于腹板顶部处的中空加强球状部分16。在图示的情况下，格栅龙骨10由两个辊轧成型金属(典型地是钢)片条制成。主体条17形成凸缘11的上部、腹板14的双壁和增强球状部分16。正面片18(典型地属于比主体条17轻的规格)形成凸缘11的外观或正面侧。正面条由以卷边的方式折叠在主体条17的纵向边缘之上的边缘纵向延伸区域19被保持在主体条之上。正面条18的外侧能够按照惯例被预涂。
按照惯例，能够提供格栅龙骨10作为主龙骨和副龙骨以形成由线材悬吊的矩形格栅。凸缘11用于将天花板砖或面板支承在由平行和相交的格栅龙骨形成的格栅空间中。面板或砖被典型地承载于凸缘11的侧向向外部分13的上侧上。
在图示的情况下，中心凸缘部分12比增强球状部分16略窄。图示的格栅龙骨10能够通过初级辊组和次级辊组在两个阶段中辊轧成型。
当条17、18离开第一辊组时，条17、18构成图1和2中所示的格栅龙骨预制件20。预制件20具有大体传统的格栅T形件形状，但是腹板14具有比普通情况大的高度。在预制件状态下，最终形成两个水平凸缘11的材料在平坦平面中延伸、与边缘卷边区域19分开、与腹板14垂直。格栅龙骨预制件20被接收在压力机中，各个细节(包括副T形件槽)和端部连接器在该压力机处形成，或者在图示的情况下，端部连接器凹入部在该压力机处形成以用于接收端部连接器。在该中间压力机站中，限位突舌26由图示于27的组合凸模和凹模组被冲压出腹板14。限位突舌26形成于腹板14的两个侧面上。每一个突舌26都具有与腹板14平行的大体平坦面28和具有部段31、32的自由边缘，所述部段31、32大体位于与腹板垂直的平面中并且彼此垂直。位于预制件20的相对侧面上的凸模和凹模组27彼此互补，使得一个单元的凸模与另一个单元的凹模一起工作并且反之亦然，以在压力机的冲程期间形成一对相邻的突舌。备选地，简单的凹凸模组能够用于在沿预制件20的长度的特定位置处形成单个突舌。腹板14的在切割边缘31、32从腹板被正确切断的位置处剩余的材料通常由凹模表面支承在突舌向其移位的腹板的侧面上。突舌面28与腹板14或最终格栅龙骨10的中心的间距被选择成将天花板面板或砖定位在格栅空间的中心处。突舌26无论是成对地位于腹板14的相对侧面上还是单个独立都被制造成邻近格栅龙骨10的每一个端部。
此外，主龙骨和长副龙骨在腹板的每一个侧面上沿其长度形成有额外的突舌。
在格栅龙骨预制件已被冲压成具有突舌26以及其它特征之后，该格栅龙骨预制件通过次级辊组。在该随后的辊轧成型步骤中，凸缘11最终成形为图4中所示的阶梯形构造。图4和7显示突舌26从外部凸缘部分13的水平面竖直向上地延伸。更精确地，突舌26的下部边缘31在卷边19的上表面之上优选地小于大约0.010英寸并且能够位于该表面处或该表面之下。通过该几何形状，突舌26能够使相对薄规格的中心天花板面板(例如0.020英寸厚)居中，而不存在面板可能在突舌之下滑移并且不居中的风险。
按照惯例将格栅龙骨并排或者侧向地嵌套以使一定量的格栅龙骨在包装中的尺寸最小从而用于运输和储存目的。图6和7示出了用于被接收在盒36(典型地是纸板容器)中的多个格栅龙骨10的包装布置。将看到交错的格栅龙骨10被布置成其相邻的上部凸缘部分13重叠。插入的格栅龙骨10翻转并且其相邻的上部凸缘部分13类似地重叠。每一个格栅龙骨的突舌26都抵靠相邻的格栅龙骨的增强球状部分16。突舌26有利地成比例，使得从腹板14的中心测量的其宽度或侧向偏移与增强球状部分16的宽度的组合大于凸缘11跨越其远侧边缘的宽度加凸缘的下降中心或中间部分12的宽度。上述的突舌几何形状防止交错的或插入的格栅龙骨的远侧凸缘边缘(由34表示)与相邻龙骨的下降中心凸缘部分12相接触。该情况示于图7中。这些元件在包装处理和运输期间接触能够造成下降中心凸缘部分12的可见表面的磨损和损坏。
将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包含在本公开中的教导的实质范围。所以本发明不限于本公开的特定细节，除非以下权利要求必然这样限制。
