Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction climbing staircase. Background Art

[0002] Building construction refers to production activities during the implementation stage of engineering construction, which includes foundation construction, main structure construction, roofing construction, decoration construction, etc. During the construction process, climbing ladders are needed to help construction workers carry out construction at high places of the building.

[0003] After searching, an anti-climbing type roof maintenance ladder with announcement number CN220365511U includes a floor slab body, two climbing ladder frames are mounted on the floor slab body, and multiple galvanized tread pipes are installed between the two climbing ladder frames from top to bottom. The climbing ladder frames are rotatably connected with an anti-climbing structure to prevent non-staff from climbing. This device is used when maintenance personnel need to go to the roof for maintenance. They can open the anti-climbing structure with a key and climb directly to the roof to work. There is no need to move other ladders back and forth to climb to the steel ladder and then go up to the roof. This greatly saves the maintenance personnel's time and maintenance efficiency, and can effectively prevent non-staff from climbing to the construction site when the roof is not completed. In addition, horizontal treads and guardrails are added to assist in climbing, which can increase the safety of workers entering the roof construction site through the structure.

[0004] Based on the above patent, by using a key to open the anti-climbing structure, one can directly climb to the roof to work, without having to move other ladders back and forth to climb to the steel ladder and then to the roof, which greatly saves the time and maintenance efficiency of maintenance personnel, and can effectively prevent non-staff from climbing to the construction site when the roof is not yet completed. In addition, horizontal pedals and guardrails are added to assist in climbing, which can increase the safety of workers entering the roof construction site through the structure. However, when a worker accidentally falls during the climbing process, the guardrail cannot effectively stop the worker from falling. Utility Model Content
