The chord assembly includes two front and rear chords, namely, the upper chord assembly includes two front and rear upper chords 3, and the lower chord assembly includes two front and rear lower chords 4. Each chord is a channel steel, and a plurality of second reinforcing ribs 9 are welded in the U-shaped groove of the channel steel. The upper male connector 1 is sandwiched between the front and rear upper chords 3, while the lower male connector 1 is sandwiched between the front and rear lower chords 4. The male connector 1 includes two sets of front and rear side panels 100, which clamp the ends of the adjacent vertical rods 5. The upper and lower ends of the vertical rods 5 connected to the male connector 1 are each provided with notches 500 on the front and rear sides, respectively. The front and rear side panels 100 of the male connector 1 are connected to the corresponding notches 500.

[0034] A guide tube 101 and a partition 102 covering the outside of the guide tube 101 are arranged between the front and rear side panels 100. The guide tube 101 has a circular hole. Male pin holes 1000 corresponding to the circular holes of the guide tube 101 are arranged on the front and rear side panels 100.
