Their main functions are to provide a working surface, ensure construction safety, and prevent people and objects from falling. Through proper design, construction, use, and maintenance, the safety of construction workers when working in stairwells can be ensured.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: when the uppermost construction work surface is not yet completed, the prefabricated stairs on the upper level cannot be hoisted into place, which will cause the work such as steel bar binding and formwork installation in the stairwell to be carried out under conditions of large differences in floor height. Generally, steel pipe scaffolding needs to be erected to provide a working platform. Erecting scaffolding is inconvenient for construction at various heights, is inconvenient to operate, and has a high risk, which affects the construction efficiency of the stairwell. Utility Model Content

[0016] This application discloses a stairwell work protection platform. By allowing construction workers to move on the prefabricated steel ladder 41, they can stop at a suitable height and position to carry out construction operations. By providing construction workers with steel platforms 51 fixed at different heights, it is convenient for construction workers to carry out work such as rebar tying and formwork installation at the suspended part on one side of the prefabricated steel ladder 41.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please refer to Figure 1 and Figure 2This embodiment provides a stairwell work safety platform, including multiple uprights 70 installed at the top of a bottom concrete surface 10, a middle concrete surface 20 at the top of the bottom concrete surface 10, a step 30 between the bottom concrete surface 10 and the middle concrete surface 20, and an ascending work platform 40 on the middle concrete surface 20. The ascending work platform 40 includes a precast steel ladder 41, guardrails 42, and supporting diagonal braces 43. The precast steel ladder 41 is installed at the top of the middle concrete surface 20 and is mounted on the middle concrete surface 20 via the uprights 70, providing protection. A guardrail 42 is installed at the top of the precast steel ladder 41, and two supporting diagonal bars 43 are symmetrically arranged on both sides of the bottom of the precast steel ladder 41. The precast steel ladder 41 is supported by the symmetrically arranged supporting diagonal bars 43. With the help of multiple uprights 70, the precast steel ladder 41 is installed on the middle concrete surface 20, so that construction workers can move on the precast steel ladder 41 to a suitable height and position at the top of the middle concrete surface 20 to carry out construction operations at the top position of the middle concrete surface 20. The guardrail 42 at the top of the precast steel ladder 41 protects the construction workers and prevents them from falling accidentally.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 The horizontal working platform 50 includes a steel platform 51 and kick feet 52. Two steel platforms 51 are positioned at different heights on one side of the precast steel ladder 41, and are installed on the central concrete surface 20 via uprights 70. Two kick feet 52 are symmetrically positioned on top of the steel platforms 51. A crossbar 60 is installed at the top between the multiple uprights 70, and multiple lifting lugs 80 are installed at the top of the crossbar 60. The steel platforms 51 on one side of the precast steel ladder 41 fill the gap in the central concrete surface 20 of the top of the step 30, allowing construction workers to work on the top of the step 30 from the central concrete surface 20. The construction team uses two steel platforms 51 at different heights to provide an operating surface for the suspended position on one side of the precast steel ladder 41, allowing construction workers to carry out construction work in the stairwell from different heights. The kick plate 52 effectively prevents operators from being injured due to accidental falls, providing an additional safety barrier and increasing the overall safety of the steel platform 51. It also prevents debris from falling from the steel platform 51. The protective platform is connected into a whole by the crossbar 60 connecting the tops of multiple uprights 70. The lifting lug 80 at the top of the crossbar 60 provides a fulcrum for hoisting, making it easy to hoist the protective platform to a suitable position in the stairwell.

[0020] The functional principle of this application can be explained through the following methods:

[0021] In use, the lifting lug 80 at the top of the crossbar 60 is fixed to the crane. The crane is then used to lift the protective platform to a suitable position on the bottom concrete surface 10 and the top of the middle concrete surface 20, so that the steel platform 51 at the bottom of one side of the precast steel ladder 41 is flush with the middle concrete surface 20. The uprights 70 on the precast steel ladder 41 and the two steel platforms 51 are bolted to the bottom concrete surface 10 and the middle concrete surface 20. Then, the two symmetrically arranged support diagonal bars 43 at the bottom of the precast steel ladder 41 are bolted to the steps 30, so that the protective platform can be fixed to the bottom concrete surface 10 and the middle concrete surface 20. On the concrete surface 20, construction workers can carry out construction at different heights of the stairs on the central concrete surface 20 from the two steel platforms 51. The kick plates 52 on the steel platforms 51 can effectively prevent operators from being injured due to accidental falls, providing an additional safety barrier and increasing the overall safety of the steel platforms 51. It also prevents debris from falling from the steel platforms 51. Construction workers enter the precast steel ladder 41 from the steel platforms 51. Construction workers can move along the precast steel ladder 41 to different positions and heights in the stairwell to carry out construction operations. The guardrails 42 protect the construction workers on the precast steel ladder 41.
