Description
技术领域
本发明涉及一种芯板,特别是一种瓦芯板。
背景技术
现有的瓦芯板包括至少两块面板以及设于两块面板之间的瓦楞芯,为了加强整体强度,现有技术是在瓦楞芯与面板之间,或者瓦楞芯与瓦楞芯之间设置加强板,然而这种结构对瓦楞芯的侧壁没有作用,尤其是用作承重板时,瓦楞芯的侧壁很容易受力变形。现有的瓦芯板也有在侧壁设置支撑结构,但结构复杂。
另外,现有的瓦楞芯采用金属板折弯形成后,瓦楞芯的侧壁面积大,散热快,进而使得瓦芯板的保温效果差。
发明内容
本发明的目的是克服现有技术的上述不足而提供一种结构简单,强度大,保温性好的瓦芯板。
本发明的技术方案是:
本发明之一种瓦芯板,包括至少两块面板和设于面板之间的瓦楞芯;所述瓦楞芯的侧壁设有加强筋,述加强筋为凹槽或凸起结构。
进一步,所述加强筋设于瓦楞芯的一侧或双侧。
进一步,所述加强筋设于瓦楞芯的侧壁内侧或外侧,或者内侧和外侧交错排布。
进一步,所述瓦楞芯的侧壁上设有通孔。通孔可与加强筋设于同一侧壁上;也可在一侧壁上仅设置通孔,另一侧壁仅设置加强筋。
进一步,所述瓦楞芯的侧壁设有多个间隔设置的加强筋,或者瓦楞芯的侧壁设有连续的加强筋。
优选地,所述瓦楞芯的顶面和底面沿面板的长度方向延伸。
进一步,所述瓦楞芯通过板体折弯成型,瓦楞芯的底面和顶面优选为平面。
进一步,所述瓦楞芯的侧壁延伸方向上均设有加强筋。
进一步,所述瓦楞芯的顶面和底面与面板之间焊接。
进一步,所述面板和/或瓦楞芯为金属材料,优选地,面板和瓦楞芯为不锈钢或碳钢材质。
进一步,所述瓦楞芯的至少一侧设有与所述面板连接的边框。
进一步,所述边框单独设置,或者所述边框为瓦楞芯直接延伸出的竖直边沿。
进一步,所述所述边框上开设有通孔和/或加强筋。
进一步,所述边框的板体为折弯或平面结构。
本发明的有益效果:(1)在瓦楞芯的侧壁设加强筋,加强筋为凹槽或凸起结构,即直接对侧壁本身进行改进,而无需设置其它加强件,不仅结构简单,还大大提高瓦楞芯的抗弯曲、抗扭性能,进而提高瓦芯板的整体强度;(2)通过在瓦楞芯的侧壁上设置通孔,能够减少瓦楞芯的导热面积,减少散热,进而提高保温效果;(3)在瓦楞芯的至少一侧设有边框,使瓦芯板在钎焊过程中起到挡风作用,进而使得热量更加集中,钎焊效率高;(4)在边框上设置加强筋,能够起到加强边框的作用;在边框上设置通孔,能够起到保温效果。
附图说明
图1是本发明实施例的结构示意图;
图2是本发明实施例瓦楞芯带边框的结构示意图;
图3是本发明实施例瓦楞芯带边框的另一结构示意图。
具体实施方式
以下将结合说明书附图和具体实施例对本发明做进一步详细说明。
如图1所示:一种瓦芯板,包括至少两块面板1和设于面板之间的瓦楞芯2;所述瓦楞芯2的侧壁23设有多个加强筋3。
上述方案具有以下优点:通过在侧壁设置加强筋3,能够提高瓦楞芯的强度,提高抗弯曲、抗扭性能,使得瓦芯板整体结构更稳定可靠,当瓦芯板受到压力后,其瓦楞芯不易产生变形。
本实施例的瓦芯板可以是多层夹芯结构,也可以是单层夹芯结构。加强筋3可以是凸起结构,例如直接在侧壁上压筋,压出凸起的筋条。可替代地,加强筋也可以是凹槽结构,可在瓦楞芯的侧壁上直接开设凹槽。加强筋的形状是任意的,如条形、圆形、方形、波浪形等,本实施例不作具体限定。本实施例的瓦楞芯通过金属板折弯成多个瓦楞槽结构,加强筋设于瓦楞槽的侧壁上。
加强筋3可设于瓦楞槽侧壁23的内侧或外侧,或者内侧和外侧交错排布。多个加强筋之间可以间隔排列,也可以一体式连接。例如:如图1所示的瓦芯板,加强筋成封闭的环形结构,多个加强筋间隔排列在瓦楞芯的侧壁上,瓦楞槽21的一侧壁外侧设有加强筋3,另一侧壁的内侧设有加强筋;且瓦楞槽侧壁的延伸方向上均设有加强筋,大大提高整体强度。又例如,加强筋也可以是连续地、一体式连接的波浪形结构。
本实施例中,面板1和瓦楞芯2为金属材质,优选为不锈钢材质。瓦楞芯2通过不锈钢板加工成瓦楞结构后整体成型。本实施例之所以整体成型,无论是吊装搬运还是芯板组装,都非常便捷,组装时,直接将瓦楞芯放置于面板之间进行固定即可,工作效率大大提高。
瓦楞芯2的顶面21和底面22均为平面,以增大与面板1的接触面积。瓦楞芯2的顶面21和底面22与面板1之间可先采用激光焊进行预固定,防止瓦楞芯在钎焊炉内产生移动,影响钎焊质量;然后再通过钎焊进行最终固定。以下为瓦芯板钎焊工艺的一个优选实施方式:
S101:将瓦楞芯放置于下面板上,且瓦楞芯与下面板之间设有钎料;
S102:对瓦楞芯的多个间隔设置的底面进行激光焊;
S103:瓦楞芯预固定在下面板上后,将上面板盖设于瓦楞芯的顶面上,且瓦楞芯与上面板之间也设有钎料;
S104:从上面板的外部对瓦楞芯进行激光焊,使上面板与瓦楞芯之间预固定;
其中,瓦楞芯顶面激光焊的密度小于底面的密度,因为顶面的焊接是从上面板的外部进行的,在保证上面板不被激光击穿的情况下使得瓦楞芯与上面板固定连接。
S105:将预固定后的瓦芯板输送至钎焊炉内,在无氧环境下,对瓦芯板进行热风循环钎焊;其中,瓦楞芯的间隙间形成贯通的气道,使的热风从各间隙间穿过,并循环,以实现钎焊。
S203:钎焊后对瓦芯板进行冷却即可输出。
在前述基础上,本实施例的瓦楞芯上还可设置通孔。优选地,将加强筋的间隔稀疏布置,在相邻加强筋之间设置通孔,既加强瓦楞芯的强度,又提高保温效果。
如图2所示:本实施例瓦芯板的另一种结构为:在前述瓦芯板的基础之上,瓦楞芯2的至少一侧设有边框4。该边框为瓦楞芯直接延伸出的竖直边沿,即瓦楞芯与边框为一体成型结构。通过设置边框,能够起到挡风作用,当瓦楞芯采用热风循环加热时,热气体在瓦楞芯中循环加热,通过边框能够减小热量扩散,提高钎焊效率。
本实施例中,边框上开设有多个间隔排列的边框凹槽41,对边框起到加强作用。此外,边框上还可开设少数的通孔,进一步保温效果。
如图3所示,本实施例边框的另一种结构为:边框与瓦楞芯为单独设置结构,边框可不与瓦楞芯连接成一体。本实施例的边框4的板体42为折弯结构,能够提高边框的强度。
可以说,本实施例的瓦芯板通过设置加强筋,能够大大提高瓦芯板的强度;通过设置边框,使得热量更加集中,大大提高钎焊效率。本实施例的瓦芯板可用于各个领域,如建筑、家具、交通工具、集装箱、桥梁、道路、隧道、轨基等。
