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.
