The multiple secondary beams 2 are arranged at intervals between the two main beams 1. The two ends of each secondary beam 2 are detachably connected to the two main beams 1 by bolts 9 respectively. One end of the two main beams 1 is fixed to the lower building structure 11 by U-shaped anchor bolts 8, and the other ends of the two main beams 1 extend out of the lower building structure 11 and are arranged in suspension. A structural plate is laid on the two main beams 1 outside the lower building structure 11. The guardrail plate 3 is detachably installed on the upper surface of the main beam 1 by bolts 9. Mounting slings 4 and load unloading slings 5 are also provided on the two main beams 1 outside the lower building structure 11. The load unloading sling 5 is connected to the pre-embedded tensioning round steel 6 on the upper building structure 10 by a steel wire rope 7.

[0033] As Figure 1 , Figure 2 and Figure 5 shown, two load unloading slings 5 and two mounting slings 4 are provided on each main beam 1 of this embodiment. The load unloading slings 5 on the two main beams 1 are arranged in one-to-one correspondence, and the mounting slings 4 on the two main beams 1 are arranged in one-to-one correspondence. The two load unloading slings 5 and the two mounting slings 4 on each main beam 1 are arranged staggeredly. The discharging platform can be hoisted through the mounting slings, and the discharging platform can be tensioned and loaded by using the load unloading slings. A steel wire rope is provided on each mounting sling 4, and a steel wire rope is provided on each load unloading sling 5.

[0034] As Figure 1 and Figure 5 shown, a limit cross beam 15 is further provided on the lower surface of the two main beams 1 of this embodiment.

The first secondary beam is 60mm away from the end of the main beam, and the spacing between each subsequent beam is 930mm and is evenly arranged. The position where each secondary beam is connected to the main beam is connected with high-strength bolts.

The high-strength bolts are 8.8S-M20 specifications, and their standard requirements meet the relevant requirements of "High-strength Large Hexagonal Bolts for Steel Structures" GB / T 1228. The guardrail plate is connected to the main beam by bolts, and the bolt specification is M12, and its standard requirements meet the relevant requirements of "Hexagonal Bolts" GB / T 5782. The guardrail adopts block material standardization protection, which is made of square steel keel and steel plate. The bottom and surrounding connection installation positions are punched on the square steel keel, and the specification is M12 bolts for fixing and connecting. Its standard requirements meet the relevant requirements of "Hexagonal Head Bolts" GB / T 5782. The square steel adopts 5*5cm square steel, the steel plate adopts 3mm corrugated steel plate, the guardrail is 1.2m high, and the square steel and steel plate of the guardrail are made of materials that meet the requirements of national standards and specifications. The connection between square steel and steel plate adopts rivets or welding. The bottom plate of the unloading platform adopts corrugated patterned steel plate with a specification of 5mm. The size is made according to the size of the unloading platform. Holes are punched at the intersection with the main beam and guardrail of the unloading platform. The guardrail and main beam are fixed uniformly when installing. The punching diameter can meet the M12 bolt fixing connection. After the unloading platform is manufactured, it is loaded and transported according to the components. When it arrives at the site, the unloading platform is assembled according to the node design. Bolts are used to connect the components. After completion, the reliability of the connection is checked. After the inspection is correct, a lifting machine is used to lift and install the unloading platform.
