[0032] The following is an example of a climbing ladder device installed on the three-story roof terrace gable of a certain residence in the north, combined with a structural schematic diagram to further illustrate the implementation idea of the present application:

[0033] The north-facing original building of the roof terrace has an out-of-roof stairwell, a concrete structure gymnasium, a height of 3000mm, and a solar water heater, an air conditioner outdoor unit and other equipment installed on the roof; the south-facing terrace accounts for about one-half of the area of the three-story roof, and is well-illuminated, so the owner added a sunroom as a tea room, and only left a 1500mm wide terrace between the sunroom and the south-facing parapet as an outdoor space to place flowers and plants. It was later found that it was difficult to climb onto the original building roof to clean up debris and maintain equipment from the remaining terrace space. Previously, because the terrace was spacious, a self-provided ladder could be used, and family members could guard and climb onto the roof to work. Now, due to the existence of the sunroom, the height of the self-provided ladder is limited, and only the outer gable can be relied on, which is very close to the open parapet. Fear of heights and danger made the climber very uneasy. This feeling is increasing with the owner's age. Even if maintenance personnel are hired, they also express difficulty in stepping on the glass ceiling with weight. If a fall occurs, the owner will bear the liability for compensation.

[0034] In view of the above practical problems, the climbing ladder device for conveniently climbing onto the roof terrace glass ceiling of the utility model is implemented as follows:

[0035] The ground of the three-layer roof terrace 23 of the house is set to 0M, and the glass roof is set to 3M. Several ladder fixed supports 10 are embedded on the outer gable 21 of the west side of the terrace. The first vertical rod 16 and the second vertical rod 17 are respectively welded on the ladder fixed supports 10, and the net interval between them is 800mm, which constitutes the ladder main support 1. The first ladder step 2 is welded between the ladder main supports 1, and the upper surface of the first ladder step 2 is 250mm away from the roof terrace 23. Then, the second ladder step 2 is welded with an interval of 200mm, and the same rule is applied to weld a total of 14 ladder steps until the upper surface of the glass roof 22, that is, the relative elevation of the roof terrace 23 is 3.05M. The height above is changed to weld a total of 4 rail bars 7 until the height of the rail exit handrail 8, and the vertical interval is still 200mm. The inner edges of all the ladder steps 2 and rail bars 7 between the ladder main supports 1 are flush with the inner edges of the two vertical rods. The first rail bar 7 of the bottom of the air protection assembly is welded at the height of the eighth ladder step 2 and wrapped with a rubber anti-collision strip. The height of the first rail bar 7 from the roof terrace 23 is 1850mm, which ensures that the head of a person does not touch it. The second rail bar 7 is 400mm away from the first one, and the same rule is applied to vertically set a total of 6 rail bars, that is, the total height of the air protection assembly is 2400mm. The third rail bar 7 adjacent to the sunroom in the north direction should be replaced with a roof climbing step 4 with a relative elevation of 3.05m to facilitate the turning action and increase the effective width of the footstep. A roof climbing step diagonal brace 5 is welded between the lower surface of the roof climbing step 4 and the second vertical rod 17 to form a triangular stable structure. The north side of the air protection assembly above the height of the roof climbing step 4 is not provided with a rail bar 7 to form a roof climbing exit. The sixth rail bar 7 of the air protection assembly in the east and west directions is extended northward by 600mm to form a rail exit handrail 8 above the glass roof. An exit cover plate 15 is arranged in the horizontal space inside the air protection assembly, and the height is the same as the upper surface of the roof climbing step 4. The exit cover plate 15 can be folded by 90 degrees towards the inside of the air protection assembly with the south rail bar 7 at the same height as the axis. In the horizontal state, it serves as a hanging work surface, and in the vertical state, it does not affect climbing. A fixed pulley horizontal support arm 13 is welded at the top of the first vertical rod 16, which extends 400mm outside the air protection assembly. A set of universal hanging fixed pulleys 12 are installed at the end of the horizontal support arm 13, and maintenance personnel can stand on the exit cover plate 15 to lift heavy maintenance items.The upper surfaces of the ladder rungs 2 and the top rungs 4 are provided with rubber anti-skid strips, and the lower surfaces are provided with inductive warning lights, the low-voltage power supply of which is a solar panel installed on the top of the fixed pulley horizontal support arm 13, and the connecting line is laid along the side surface of the first vertical rod, and the electrically charged materials are waterproof; the monitoring device 20 is installed on the fixed pulley horizontal support arm 13 and is also powered by the solar panel, can patrol the maintenance activities of the owner or the worker, and also monitors the illegal intrusion, and immediately alarms when there is an emergency or theft, and plays an auxiliary role in safety emergency and theft prevention.

[0036] The person climbing ladder device disclosed by the utility model is convenient for the owner to daily or maintenance workers to climb the expanded sunlight room glass roof to work, and can not need others to keep watch, is safe and labor-saving. The person climbing ladder device conforms to the ergonomics principle, has the characteristics of simple structure, convenient implementation, low cost and safety and firmness, reduces the fear of the owner, especially the empty-nest old people, when climbing, effectively avoids the falling accidents caused by the maintenance workers when climbing with load, has the monitoring and anti-theft functions, has the remarkable beneficial effects in the safety, practicality and convenience, and is worth popularizing and applying.
