具体实施方式
接下来将参照附图详细描述本发明的单层塑料复合板。这里所描述的仅仅是根据本发明的优选实施方式，本领域技术人员可以在所述优选实施方式的基础上想到能够实现本发明的其他方式，所述其他方式同样落入本发明的范围。
图1是根据本发明的一个优选实施方式的单层塑料板的示例性截面视图。如图1所示，单层塑料板11具有主体部111和位于主体部111四周的周边部，主体部111为大体平面形状并且具有正面和与正面相对的背面，周边部沿与主体部111垂直的方向向主体部的背面弯折形成弯折部112。主体部111上可具有起美观作用的通过印刷制成的图案。并且，主体部111还可以通过直接挤出成型或挤出后吸塑成型形成凹凸造型，这样除了美观作用外，还可以起到增加单层塑料板强度的作用。具体参见图2，图2为图1中单层塑料板的正面视图，其中，单层塑料板11的主体部111上具有凹凸造型113，该凹凸造型113进一步成型为网格状，从而可以进一步增加单层塑料板11的强度。另外，所述图案或凹凸造型根据应用场合和美观的需要可以具有某些天然材料的形状，例如图2中示例性示出的编织藤条形状。并且，如图2所示，凹凸造型113还进一步形成了符合人体工程学的便于手扶的扣手状结构114。
图3为根据本发明的一个优选实施方式的金属加强件12的截面视图。金属加强件12为单层金属板通过弯折轧制而成的条状部件或框状部件。图3具体示出了示例性金属加强件12的截面形状，如图所示，当从截面上观察时，金属加强件12包括互相垂直的第一区段121和第二区段122，第一区段121为双层结构，而且第一区段121的外层的长度大于第一区段121的内层的长度，第一区段121的外 层的末端弯折成与第二区段122平行并沿着第二区段122的外侧延伸第二区段122的长度的一部分，由此在第一区段121的外层的末端与第二区段之间形成间隙1221。并且部分重叠的两层金属板之间不贴合，而是留有间隙1221。间隙1221的形状及尺寸与图1所示单层塑料板11的弯折部112的形状及厚度大致匹配，当金属加强件12套在单层塑料板11的弯折部112上时，间隙1221能够将弯折部112的至少一部分紧密容纳在其中。
图4为根据本发明的一个优选实施方式的单层塑料复合板10的局部截面视图。如图所示，单层塑料复合板10是包括图1所示的单层塑料板11和图3所示的金属加强件12的两件式单层塑料复合板，其中，单层塑料板11的弯折部112的一部分紧密适配在金属加强件12的第二区段122的间隙1221中。单层塑料板11与金属加强件12之间可以通过胶水等粘结剂固定，也可以通过借助摩擦力等其他方式固定。
在本发明的另一个优选实施方式中，金属加强件12还可以具有第三区段123。第三区段123与第二区段122邻接，其自第二区段的末端沿着与所述第二区段垂直的方向朝第二区段的内侧延伸。当金属加强件12套在单层塑料板11的弯折部112上时，第三区段123与单层塑料板11的主体部111贴合，这种构造可以进一步扩大单层塑料板11与金属加强件12的粘结面积，以使它们之间的固定更加牢靠，并且通过第三区段123对单层塑料板11的主体部111的边缘的支撑作用，还能够进一步增加单层塑料复合板的边缘的强度。
需要说明的是，金属加强件12可以是适应单层塑料板11的周边形状的整体框架结构，也可以是可拼接成适应单层塑料板11的周边形状的多个条形结构。另外，第三区段123不是必需的，即，金属加强件12可以仅由第一区段121和第二区段122构成。
本发明的单层塑料复合板中的加强件可以是其他形式的，例如可以是通过挤出成型的截面为闭合形状的金属管状件或塑料管状件，这种加强件的优点是容易制造、生产成本低，并且由于其截面 形状是闭合的，所以强度更高，能够更好地支撑单层塑料板以为其提供额外的强度，使得单层塑料板可以采用较小的厚度并由此进一步减少用料，降低成本。图5示例性地示出了根据本发明的一个优选实施方式的加强件22的截面视图，其中加强件22的截面形状为闭合的方管状。从图中可见，加强件22具有第一区段221和与其邻接且垂直的第二区段222，第二区段222在其远离第一区段221的末端上形成有沿垂直于第二区段222的方向向加强件22的外侧延伸的凸缘2221。
图6是根据本发明的一个优选实施方式的单层塑料复合板20的局部截面视图，其中图5所示的加强件22与单层塑料板11接合并固定。如图所示，第一区段221与单层塑料板11的主体部111贴合，第二区段222与单层塑料板11的弯折部112贴合，并且，第二区段222上的凸缘2221的宽度与单层塑料板11的厚度相当，凸缘2221与弯折部112的边缘接合，以进一步支撑固定单层塑料板11。
图7示例性地示出了根据本发明的一个优选实施方式的加强件32的截面视图，其中加强件32为截面形状闭合的内凹的管状件，示例性地，所述内凹形状可以是阶梯形状。如图所示，加强件32具有第一区段321和沿与其垂直方向延伸的第二区段322，同样地，第二区段322在其远离第一区段321的末端上形成有沿垂直于第二区段322的方向向加强件32的外侧延伸的凸缘3221。与加强件22不同的是，加强件32还具有第三区段323，第三区段323位于第一区段321与第二区段322之间，向管内凹陷并与第一区段321和第二区段322共同构成阶梯形状。
图8是根据本发明的一个优选实施方式的单层塑料复合板30的局部截面视图，其中图7所示的加强件32与单层塑料板11接合并固定。如图所示，第一区段321与单层塑料板11的主体部111贴合，第二区段322与单层塑料板11的弯折部112贴合，并且，第二区段322上的凸缘3221的宽度与弯折部112的厚度相当，凸缘3221与弯折部112的边缘接合以进一步支撑固定单层塑料板11，由于第三区 段是内凹的，所以第三区段323与单层塑料板11之间形成空腔。
图9是根据本发明的一个优选实施方式的单层塑料复合板40的局部截面视图，其中图7所示的加强件32单层塑料板21接合并固定。与单层塑料板11不同的是，单层塑料板21的弯折部212成阶梯形状，与加强件32的第二区段322和第三区段323组成的形状相匹配。具体地，第一区段321与单层塑料板21的主体部211的边缘贴合，第二区段322和第三区段323与单层塑料板21的弯折部212贴合。类似地，第二区段322上的凸缘3221的宽度与单层塑料板21的厚度相当，凸缘3221与弯折部212的边缘接合以进一步支撑固定单层塑料板21。
图10A和10B示意性地示出了据本发明的优选实施方式的单层塑料复合板的加强件的截面视图，其中加强件的凸缘2221、3221的下侧还可设置有自其向下延伸的翼部2222、3222。
需要说明的是，以上所述各种实施方式中的第一区段可以不像图中所示的那样与单层塑料板的主体部贴合，在本发明的其他优选实施方式中，第一区段与主体部的边缘之间也可以具有一定的间隙。除此之外，以上所述各种实施方式的加强件可以是适应单层塑料板的周边形状的整体框结构，也可以是可拼接成适应单层塑料板的周边形状的多个条形结构。以上所述各种实施方式的加强件与单层塑料板之间可以通过胶水等粘结剂粘结固定，并且当加强件的材料为塑料时，还可以通过超声焊接进行连接固定。
本发明的单层塑料复合板由于具有重量轻、强度高、成本低、易加工、组装方便等特点，其用途非常广泛，例如，可以用于组装柜子、箱子、桌椅等家具。本发明的图11示例性地示出了由本发明的单层塑料复合板组装而成的箱子100，其中塑料板上具有仿编织藤条的形状结构，既能起到美观的作用，还能增加塑料板的强度，同时，为了便于搬运，单层塑料复合板上的纹路或图形还形成了扣手结构。
