Description

夹板
技术领域
本发明在最广义上可被定义为一种建筑单元，即，一种具有由呈曲折褶皱形式的起皱片材制成的轻质芯的夹板。
技术背景
已知有一种夹板，它包括与芯层相连接的外皮，其中，所述的芯通过使片材坯件沿着在展开面上所划出的突部和凹部曲折线进行弯曲来获得(发明人证书号为SU no.1,785,154。具有曲折起皱芯的曲线夹板的制造方法，-国际分类号为B23K20/00，-93年7月30日的公告第28条)。
这里所描述的这种夹板的主要缺点是外皮-芯的低连接强度和低可靠性，这是由于小的接触面积的缘故。
已知有一种夹板，它具有由起皱片材制成的轻质芯(RF专利号no.2,038,265C1.夹板.-国际分类号为B64C3/26.-于95年6月27日公开)。其目的是，增大芯与下部外皮的接触面积，褶皱突脊被制造成荚状(lenticular)元件的形式，这些荚状元件位于所述突脊的凹部，而在芯的顶点处位于该芯的侧突脊之间的曲线合成材料则增大了芯与上部外皮的接触面积。
这里所描述的这种夹板的主要缺点是不能简单地沿着褶皱的凹部线来形成芯，以及沿着突部线来实现所述接触面积需要高的劳动成本；这导致了夹板的总体成本增加(writing up)。
被当作原型的是这样一种夹板，这种夹板包括外皮并且曲折起皱芯被放置在所述外皮之间，具有交替的突部和凹部的曲折起皱芯包含沿着所述的突部和凹部延伸的三角形凹槽，这些三角形凹槽被填充有胶粘合成材料(发明人证书号为RF no.1,646,196A1。夹板.-国际分类号为B64C3/26.-96年12月27日的公告第36条)。
这里所描述的这种夹板的主要缺点是由于褶皱形状在其侧部区域中的复杂性，从而需要一些精密的和昂贵的成形工具来制造芯。然而，技术上的困难使得不可能以褶皱的相当小的高度在该褶皱的突部和凹部上形成凹槽。褶皱形状的额外折叠降低了芯块的高度的精确性；这对板片的质量产生了不利的影响。技术上可实现的凹槽区域尺寸增大了面积，因此，增大了芯的质量，从而需要增加所应用的胶粘合成材料，这对板片的重量效率产生了不利的影响。
发明内容
本发明的目的是增加折叠的芯-外皮的粘合强度。
实施所要求保护的发明所获得的技术效果是改进了夹板的单位-重量(unit-weight)性能，这是由于芯和胶粘合成材料的质量减小的缘故。
所述的技术效果是通过以下事实来获得的，即，一种夹板，包括有两个外皮和曲折起皱芯，所述的曲折起皱芯具有交替的突部和凹部，所述交替的突部和凹部布置在所述外皮之间并利用胶粘合成材料与所述外皮相连接，其中：沿着曲折弯曲线形成穿孔线，以使得在曲折起皱芯与所述外皮的组装过程中使胶粘合成材料能够穿过穿孔线的孔而进入褶皱中，从而在褶皱中形成铆钉的头部和主体。
申请人通过对现有技术的分析，表明现有技术中没有与本发明中的特征组合相类似的特征组合。因此，所要求保护的技术方案满足专利性中的“新颖性”条件。
通过在给定领域检索与所要求保护的技术方案的特征部分相同的技术特征，检索结果表明所要求保护的技术方案的特征部分的技术特征并不是来自于现有技术。从申请人尽力揭露的现有技术来看，所确定的必要技术特征对所声称的技术效果没有影响。因此，本发明所要求保护的技术方案满足专利性中的“创造性”条件。
附图说明
图1-4表示出了本发明的要素：
图1是具有曲折折叠芯的夹板的总体示意图；
图2表示具有沿着曲折弯曲线的穿孔的芯平面坯件；
图3是图1的A-A剖面图，表示芯-外皮沿着曲折线沿着穿孔进行粘合；
图4是图2的B-B剖面图。
图1-4表示出了下列位置：
1是下部和上部外皮；2是折叠(起皱)芯；3是褶皱突部曲折线；4是凹部曲折线；5是褶皱锯齿状线；6是胶粘合成材料。
具体实施方式
夹板包括下部外皮1(图中未表示上部外皮)和具有曲折褶皱的折叠芯2，该折叠芯2呈交替的突部和凹部的形式，通过使片材坯件沿着突部曲折线3、凹部曲折线4和锯齿状线5进行弯曲来获得所述的折叠芯2。平坯件(plains)通过突部曲折线3和凹部曲折线4形成平面侧面，这些平面侧面的相交轨迹代表褶皱的锯齿和曲折线。沿着褶皱线即突部曲折线3和凹部曲折线4形成在芯材料曲线弯曲部分上的是线性穿孔，该线性穿孔在芯坯件材料展开(在成形之前)状态下被形成在该芯坯件材料中。折叠芯2沿着皱褶线即突部曲折线3和凹部曲折线4利用胶粘合成材料6与下部外皮及上部外皮1相连接。与此同时，所取的每个穿孔的面积、胶粘合成材料6的粘度及其质量能使得胶粘混合物(compound)通过所述的孔进入褶皱中，在这些褶皱中，所述的混合物形成滴；在芯-外皮粘合之后的胶水聚合过程中，所述的滴形成铆钉的头部和主体。
由芯突脊上的穿孔所引起的材料的部分残缺不会不利地影响夹板的强度属性，这是由于其剪切强度主要由稍倾斜的芯元件即突脊的质量来决定的。突脊被用作芯-外皮的粘合表面，并且在小范围内决定夹板的强度。总的来说，所要求保护的方法由于“铆接”的缘故增加了胶接强度，因而提高了夹板的质量，并且由于减少了芯材料质量和胶粘材料，因而增加了夹板的重量效率。
工业实用性
所要求保护的发明能够被用于飞机建造、造船以及建筑物。
