The invention provides a composition board, an arm support and an operation machine, which comprises a base plate which is a metal plate, a connecting plate which is arranged on one side of the base plate and is connected with the base plate, a fixing plate which is arranged at one end of the base plate connected with the connecting plate, and at least part of the connecting plate is located between the base plate and the fixing plate. The connecting piece penetrates through the fixing plate, the connecting plate and the base plate to connect the base plate with the connecting plate. And/or the reinforcing plate is arranged at the end, connected with the base plate, of the connecting plate, and the connecting piece penetrates through the reinforcing plate, the connecting plate and the base plate to connect the base plate with the connecting plate. According to the technical scheme, the connecting strength of the connecting position between the connecting plate and the base plate is enhanced, the local thickness of the whole component can be reduced while the connecting strength of the connecting position is improved by locally thickening the connecting position between the connecting plate and the base plate, and then the weight of the whole component is reduced.

    本发明提供了一种组合板、臂架和作业机械,包括:基板为金属板,连接板设置于基板的一侧,并与基板连接,连接板为复合材料板,固定板设置在基板与连接板连接的一端,连接板的至少部分位于基板与固定板之间,连接件贯穿固定板、连接板以及基板将基板与连接板连接;和/或,加强板设置在连接板与基板连接的一端,连接件贯穿加强板、连接板及基板将基板与连接板连接。通过上述技术方案,增强了连接板与基板之间连接处的连接强度,且通过对连接板与基板的连接处进行局部加厚,在提高连接处连接强度的同时,还可以降低整个构件的局部厚度,进而减轻整个构件的重量。
