The upper surface of the second support beam 6 is flush with the upper surface of the first support beam 5, so that the upper surfaces of the first support beam 5 and the second support beam 6 in contact with the cable during cable support are flat surfaces without steps, avoiding cable damage caused by the existence of steps.

[0040] Optionally, the fixing member 1 is a first C-shaped steel, and a channel with one side open is formed inside the first C-shaped steel.

[0041] Specifically, the fixing member 1 adopts a steel section, with a simple structure and low cost.
