Preferably, the auxiliary support plate 7 is arranged horizontally in the middle of the outer column 2, and the auxiliary support plate 7 is fixedly connected to the two adjacent outer columns 2. The auxiliary support plate 7 is fixedly connected to the two middle columns 4 through a connecting plate 9. A plurality of storage components 8 are slidably connected to the side walls of the outer columns 2 fixedly connected to the auxiliary support plate 7. Preferably, the storage components 8 are distributed on the upper and lower sides of the auxiliary support plate 7, and a limiting component is arranged on the storage component 8, and the limiting component is used to lock the storage component 8 on the outer column 2. In actual use, the standardized protective stair operating platform described in the utility model can be transported to the construction site by a crane or other mobile equipment, and used in conjunction with a lifting platform or a load-bearing platform, which is convenient and fast; and the arrangement of the auxiliary support plate 7 and the storage component 8 can facilitate construction personnel to temporarily place and stack construction materials and tools, without the need to frequently go up and down the stairs for transportation, which can effectively save construction time and improve construction efficiency.

[0026] like Figure 1-4 As shown, the storage component 8 further includes: a storage frame 801, which is used to place tools required for construction to prevent construction workers from carrying too many tools and affecting construction efficiency. A slider 802 is fixedly connected to the side of the storage frame 801 close to the outer column 2. A slide groove 201 that cooperates with the slider 802 is provided on the outer column 2. The storage frame 801 is slidably connected to the outer column 2, which is convenient for construction workers to adjust the height of the storage frame 801 according to the construction height, and the applicability is stronger.
