In existing hanging basket structures, welded guardrails are commonly used around the upper surface of the base plate. There are certain disadvantages in their use. For example, the existing guardrails and the base plate are mostly fixed by welding, and their later disassembly and transportation are more troublesome, which affects the convenience of use and the practicality of the device.

The technical solution is as follows:

[0005] A safety protection device for steel structure construction includes a base plate and a plurality of protection plates installed around the upper end surface of the base plate, a plurality of positioning frames are fixed to the bottom of the protection plate, the positioning frames are snapped onto the side surfaces of the base plate, two groups of positioning columns are symmetrically fixed at both ends of the outer side of the protection plate, and the positioning columns on two adjacent protection plates are connected by a connecting assembly.

[0006] Furthermore, the positioning column is provided with a transverse through hole 1 and three longitudinal through holes 2, the connecting assembly includes a transverse plate and a connecting rod, a threaded rod is fixed at the bottom of the transverse plate, positioning rods are symmetrically provided at both ends of the transverse plate, the connecting rod is a straight rod or an "L"-shaped rod, the connecting rod is provided with a through hole 3 matching the through hole 2, the connecting rod is inserted into the through hole 1 of the two adjacent protective plates, the threaded rod and the positioning rod are both inserted into the through hole 2 and the through hole 3, and the outer end of the threaded rod is fastened by a nut.

[0007] Furthermore, the positioning frame is a U-shaped frame and is fixed on the base plate by bolts.

[0008] Furthermore, the diameter of the connecting rod is equal to the diameter of the through hole one.

[0009] Furthermore, the threaded rod and the positioning rod have the same diameter, and are equal to the diameters of through hole two and through hole three.

[0010] Furthermore, a fixing rod is fixed on the inner side of the protective plate for workers to hold and fasten the safety rope.

[0011] Furthermore, a connecting ring is fixed on the top of the protective plate for connecting to a crane.

[0012] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the utility model can quickly install the protective plate on the base plate through the positioning frame, and the connection and fixation between two adjacent protective plates can be easily achieved through the connecting assembly. The protective plate can be quickly disassembled by removing the nut and the bolt on the positioning frame. After disassembly, the volume of the device can be effectively reduced, which is convenient for later transportation. The fixing rod can be used by the staff to hold and tie a safety rope, thereby improving the safety of the device and having strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
