[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] A prefabricated safety work platform includes a frame assembly 1, a support assembly 2 welded under the frame assembly 1, a multi-functional staircase 3 at the bottom of the frame assembly 1, the multi-functional staircase 3 including several treads 31, L-shaped blocks 32 fixedly connected to the bottom sides of the treads 31, a first connecting column 35 and a second connecting column 36 installed parallel to each other on both sides of the L-shaped blocks 32, and a standing platform 4 laid at the bottom of the frame assembly 1.

[0026] The frame assembly 1 includes a bottom frame 11, which is welded from several angle steels. Several guardrail posts 12 are welded to the perimeter of the bottom frame 11, and a ring of guardrail beams 13 is welded to each guardrail post 12. Four rectangularly distributed first fixing plates 14 are welded to the inner side of the bottom frame 11. Each first fixing plate 14 has several bolt holes, and a kick plate 15 is welded to it. A manhole is provided within the bottom frame 11, and a hinged opening plate 16 is rotatably connected to one side of the bottom frame 11 via a hinge. The other side of the opening opening plate 16 is connected to the bottom frame 11 via a pin. The first fixing plates 14 are fixed to the outside of the template with bolts, thus installing the entire frame assembly 1 on the outside of the template. The kick plate 15 effectively prevents operators from accidentally stepping into gaps from the inside, enhancing bottom protection. The guardrail posts 12 and guardrail beams 13 are interconnected, providing reliable safety for the construction site. When the multi-functional staircase 3 needs to be moved, simply open the latch and then rotate the hinge plate 16 to move it. When the multi-functional staircase 3 needs to be converted into a platform, the hinge plate 16 is firmly fixed to the bottom frame 11 with the latch, so that the hinge plate 16 can provide the necessary support for the multi-functional staircase 3 and ensure that the multi-functional staircase 3 can be transformed into a sturdy platform.

[0027] It should be noted that a safety net is installed between the guardrail post 12 and the guardrail beam 13 to prevent workers from accidentally stepping into the gap during construction, thereby reducing the risk of accidents and ensuring the safety and stability of the working environment.

[0028] It should be noted that the standing platform 4 is laid on top of the bottom frame 11, providing operators with a spacious and stable standing area, thereby effectively preventing operators from accidentally stepping into the air during operation and improving the safety of the construction site.

[0029] The support assembly 2 includes two support columns 21 welded to the first fixed plate 14, with the support columns 21 located below the first fixed plate 14. Four inclined blocks 24 are welded between the support columns 21, and the inclined blocks 24 are located at the four corners below the first fixed plate 14. A second fixed plate 22 is welded to the support columns 21, and the second fixed plate 22 has several bolt holes. Diagonal braces 23 are welded to the second fixed plate 22, and the other end of the diagonal braces 23 is welded to the bottom frame 11. The second fixed plate 22 is fixed to the outside of the template by bolts, thereby enhancing the structural stability of the entire frame assembly 1. The support columns 21 and the diagonal braces 23 form a robust support system, providing all-round and balanced support for the frame assembly 1. The inclined blocks 24 further ensure the integrity and stability of the platform, making the entire structure safer and more reliable.

[0030] The first tread 31 of the multi-functional staircase 3 is connected to the frame assembly 1 via a hinge. The multi-functional staircase 3 is located at the manhole. The horizontal end of the L-shaped block 32 has a second hole 34, and the vertical end of the L-shaped block 32 has a first hole 33. Several L-shaped blocks 32 are connected to the second connecting column 36 via rotating shafts through the second holes 34, and several L-shaped blocks 32 are connected to the first connecting column 35 via rotating shafts through the first holes 33. When converting from a platform to a ladder, moving the last tread 31 downwards rotates the first connecting column 35 within the first hole 33, simultaneously rotating the second connecting column 36 within the second hole 34. This causes the L-shaped blocks 32 to move downwards, thus moving the tread 31 downwards to form the ladder. When converting from a ladder to a platform, moving the last tread 31 upwards places it on the opening and closing plate 16, thus forming a stable platform.

[0031] It should be noted that the total length of the treads 31 matches the manhole. When the multi-functional staircase 3 is converted into a platform state, these treads 31 can cover the manhole area, effectively preventing workers from stepping into the manhole during concrete pouring operations, thus providing a solid guarantee for safe operation on the construction site.

[0032] The entire device is hoisted to the top of the pier formwork using a crane, and then lowered. The last step 31 is moved down, causing the first connecting column 35 to rotate within the first hole 33, and simultaneously causing the second connecting column 36 to rotate within the second hole 34. This causes the L-shaped block 32 to move downwards, thereby moving the step 31 downwards to form a ladder.

[0033] Workers climb ladders onto standing platform 4, which is laid above the bottom frame 11, providing a spacious and stable standing area for operators. This effectively prevents operators from accidentally stepping into gaps during work, improving the safety of the construction site. Workers use bolts to fix the first fixing plate 14 to the outside of the formwork, thus installing the entire frame assembly 1 on the outside of the formwork. The kick plate 15 effectively prevents operators from accidentally stepping into gaps from the inside, enhancing bottom protection. The guardrail posts 12 and guardrail beams 13 are interconnected, providing reliable safety for the construction site. A safety net is installed between the guardrail posts 12 and guardrail beams 13 to prevent operators from accidentally stepping into gaps during construction, thereby reducing the risk of accidents and ensuring the safety and stability of the working environment.

[0034] The second fixing plate 22 is fixed to the outside of the template by bolts, thereby enhancing the structural stability of the entire frame assembly 1. The support column 21 and the diagonal brace 23 form a robust support system, providing all-round and balanced support for the frame assembly 1, while the diagonal block 24 further ensures the integrity and stability of the platform, making the entire structure safer and more reliable.

[0035] When workers pour concrete, the ladder needs to be converted into a platform. The last step 31 is moved upwards and placed on the hinged plate 16, forming a stable platform. To move the multi-functional staircase 3, simply open the latch and rotate the hinged plate 16. When converting the multi-functional staircase 3 into a platform, the hinged plate 16 is securely fixed to the bottom frame 11 with the latch, providing necessary support and ensuring the multi-functional staircase 3 can be transformed into a sturdy platform. The total length of the steps 31 matches the manhole. When the multi-functional staircase 3 is converted into a platform, these steps 31 cover the manhole area, effectively preventing workers from stepping through the manhole during concrete pouring, providing a solid guarantee for safe operation on the construction site.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
