Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically to a stable connection structure for a ladder. Background Technology

[0002] In bridge construction, ladders are a commonly used connection device. Ladders have good stress characteristics, are easy to connect, and are highly reusable. Their application greatly improves the safety of high-altitude construction and can be widely used in various aspects of bridge construction, including cast-in-place scaffolding, construction work platforms, and foundation pit engineering. However, the attachment of ladders is also one of the most accident-prone aspects of municipal bridge construction. Currently, most high-altitude construction in China uses standardized safety ladders to provide access for personnel. In actual construction, because there are no readily available structures on site for ladder attachment, standardized safety ladders cannot be effectively connected to the construction work platform. This leads to the conventional practice of simply fixing the safety ladder to the side using wind cables, but this approach has the following problems:

[0003] (1) Since the ladder is not reliably connected to the structure, it often shakes severely and poses a significant safety risk during actual use.

[0004] (2) At the same time, because the workers are swaying at high altitudes, the efficiency is extremely low and the construction quality is also poor.

[0005] (3) The ladder is attached by pre-embedded parts. The post-processing of the pre-embedded parts is more troublesome and can easily cause appearance quality problems. Utility Model Content
