Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails and relates to a foldable and movable guardrail for building construction. Background Art

[0002] At present, the protective railings at the edge openings of industrial and civil buildings such as foundation pits, floors, and platforms are installed by combining scaffolding steel pipes and shaped railings to form protective guardrails, which leads to random installation. Since there is no reliable and fast folding and moving device, it is impossible to ensure that the foundation pit is excavated in sections, backfilled with earth, masonry, and permanent railings can be folded and moved to other foundation pits, floors, platforms, and other edge openings before installation. The removal, transportation, and re-erection of the protective railings take a long time, and there are safety hazards such as the lack of protective installation in time. Furthermore, the folding and movement of the protective railings can be conveniently achieved through telescopic means. For example, the CN201620932285.7 telescopic foundation pit edge guardrail achieves the telescopic effect through the slide groove and the fixing effect through the locking piece. First of all, most of the current retractable guardrails do not have protective nets; secondly, the current transportation of guardrails requires them to be dismantled section by section and then transported to conveying equipment for transfer or storage; some guardrails use solid steel columns or cement cores to increase weight to prevent overturning, and guardrails weighing dozens of kilograms need to be frequently transported, resulting in high labor intensity.
