[0028] Specifically, Figure 2 As shown, both ends of the straight back rib 1 are provided with a plurality of circular through holes for fixing the standard connectors 2 or the male corner connectors 3 or the female corner connectors 4, and the standard connectors 2, the male corner connectors 3 and the female corner connectors 4 are all provided with a plurality of waist-shaped through holes for fixing with the straight back rib 1 and adjusting the length.

[0029] like Figure 7 and Figure 8As shown, according to another embodiment of the utility model, this embodiment further optimizes the specific structure of the external corner connector 3. Exemplarily, the external corner connector 3 includes two external corner bending profiles 31, whose cross-section is square, and the two ends of the external corner bending profiles 31 are symmetrically provided with external corner reinforcement plates 32, the cross-section of the external corner reinforcement plates 32 is square and the number is two; one end of the two external corner bending profiles 31 is fixedly provided with an oblique angle code 33, and the two oblique angle codes 33 are connected and fixed by oblique bolts 6 so that the two external corner bending profiles 31 are perpendicular to each other; a plurality of waist-shaped through holes are provided on the two external corner bending profiles 31, and circular through holes are provided at both ends of the straight back ribs 1, and the ends of the two external corner bending profiles 31 away from the oblique angle code 33 are respectively provided at one end of the two straight back ribs 1, and are fixed with the straight back ribs 1 by fixing bolts 77.

[0030] like Figure 5 and Figure 6 As shown, according to another embodiment of the utility model, this embodiment further optimizes the specific structure of the internal corner connector 4. Exemplarily, the internal corner connector 4 includes two internal corner bent profiles 41, a internal corner end reinforcement sheet 42 and a internal corner corner reinforcement sheet 43. The two internal corner bent profiles 41 are fixedly connected to form an L-shape, and the cross-sections of the two are square, and internal corner reinforcement sheets are symmetrically arranged at both ends of the internal corner bent profile. The cross-sections of the internal corner reinforcement sheets are square and there are two of them; the cross-sections of the internal corner end reinforcement sheets 42 are square, there are two of them and they are arranged at both ends of the internal corner bent profile 41; the cross-sections of the internal corner corner reinforcement sheets 43 are square, there are two of them and they are arranged at the upper and lower sides of the L-shaped connection of the internal corner bent profile 41. The inner corner bending profile 41 is provided with a waist-shaped through hole for the screw to pass through, and both ends of the straight back rib 1 are provided with circular through holes. One end of the two straight back ribs 1 is respectively arranged at the end of the inner corner bending profile 41 away from the corner, and is fixed by fixing bolts 77.
