The invention discloses a triangular truss arm unit body which comprises three main chord members arranged in parallel pairwise. The three main chord members form a triangular prism structure, a top web member is connected between the upper parts of the main chord members pairwise, and the three top web members form a triangular structure perpendicular to the main chord members. Bottom web members are connected between the lower parts of every two main chord members, the three bottom web members form a triangular structure vertical to the main chord members, middle web members which are repeatedly arranged in a zigzag shape are connected between every two main chord members, and the middle web members are positioned between the top web members and the bottom web members. The invention further discloses a combinable reinforced truss arm which is obtained by combining the triangular truss arm unit bodies. According to the combinable reinforced truss arm and the triangular truss arm unit body thereof, disassembly and assembly are convenient, the structural stability is high, the combination forms are diversified, and the transportation size standard is met.

    本发明公开了一种三角形桁架臂单元体,包括三根两两平行设置的主弦杆,三根所述主弦杆形成三棱柱结构,所述主弦杆上部两两之间连有顶部腹杆,三根所述顶部腹杆形成与所述主弦杆垂直的三角形结构,所述主弦杆下部两两之间连有底部腹杆,三根所述底部腹杆形成与所述主弦杆垂直的三角形结构,两两所述主弦杆之间连有呈之字形重复排列的中部腹杆,所述中部腹杆位于所述顶部腹杆和底部腹杆之间。本发明还公开一种可组合增强的桁架臂,由上述三角形桁架臂单元体组合得到。本发明提供的一种可组合增强的桁架臂及其三角形桁架臂单元体,方便拆装,结构稳定性变强,组合形式多样化且满足运输尺寸标准。
