Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction auxiliary devices, in particular to a pedestrian ladder support pad. Background Art

[0002] During construction work on highways, railways, bridges, tunnels, piers, and other structures, ladders and cages are often used as auxiliary tools for ascending heights. With socioeconomic development, the volume of construction projects on highways, railways, bridges, tunnels, piers, and other structures has increased, and the use of ladders and cages has also increased. Many companies in my country are promoting the reuse of surplus materials and green construction. Therefore, the use of ladders and cages requires not only safety assurance but also tool utilization and cost efficiency.

[0003] As safety requirements for ladders and cages increase, support pads are required at the bottom to prevent them from sliding or tipping over. Currently, commonly used ladders and cages come with built-in steel pads. These pads have a small surface area attached to the ground and require high ground flatness. If uneven force is applied to the small surface area, they are prone to sliding or tipping over, posing a safety hazard to workers during construction. Furthermore, most ladder and cage support pads are currently integrated into the main structure and are non-reusable, resulting in a low utilization rate. Many construction companies generate some steel scrap during construction. Selecting some of this scrap to make safe and reliable ladder support pads is of great significance, as it allows for the recycling of the steel scrap while ensuring the safety of the ladder. In view of this, a reusable and portable ladder support pad was invented and a patent application was submitted. Application number: 202223139748.9, filing date: 2022.11.25. Abstract: The utility model discloses a reusable and portable ladder support pad, which includes a precast concrete base, a ladder support sleeve, and a ladder support flange plate. The precast concrete base is pre-embedded with a lifting ring and embedded bolts. The ladder support sleeve is vertically welded to the top of the ladder support flange plate. The ladder support flange plate is provided with bolt holes corresponding to the positions of the embedded bolts. The bolt holes in the ladder support flange plate are passed through the embedded bolts and then fixed to the precast concrete base by nut fasteners. The ladder support pad has a simple structure, is easy to assemble and disassemble, can be recycled to adapt to different types of ladders, improves utilization, effectively solves the problem of support and positioning stability during ladder use, and greatly ensures construction safety during ladder use.

[0004] Application research has found that the above disclosed reusable portable ladder support pad is rather troublesome to install during construction, and the original foot pad of the pedestrian ladder needs to be removed before the support pad can be installed, and the installation application range is relatively small.
