Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, in particular to a portable safety operating platform for wet joint and beam construction. Background Art

[0002] After the bridge beams are erected, the joints between adjacent beams need to be welded with rebar and poured with concrete. When working on wet joints and under beams, workers typically use hanging baskets or portable construction platforms to provide a foothold. These platforms allow them to perform rebar welding and formwork installation at the bottom of the beams.

[0003] Regarding hanging baskets or portable construction platforms, Chinese patent document CN 209923789 U (application number 201920207605.6) discloses a foldable hanging basket for the construction of prefabricated box girder diaphragms, comprising a first hanging ladder, a second hanging ladder, and a hanging basket base frame. The bottoms of the first hanging ladder and the second hanging ladder are respectively hinged to the hanging basket base frame, so that the bottoms of the first hanging ladder and the second hanging ladder can rotate around the hinge point, thereby realizing the folding of the hanging basket. After folding, the hanging basket occupies a small space and is easy to carry; a rotating support mechanism is provided between the first hanging ladder and the second hanging ladder.

[0004] For example, Chinese patent document CN 216973135 U (application number 202123256483.6) discloses a safety protection hanging basket for the construction of a central beam of a bridge deck system, comprising a working pedal, a protective chain and an anti-slip ladder; the working pedal located at the bottom of the protective hanging basket comprises a connecting pedal and a first footboard, and the two first footboards are respectively arranged on the opposite sides of the connecting pedal; the two anti-slip ladders are arranged opposite to each other and are respectively connected to the two sides of the connecting pedal where the first footboard is not provided, and the two sides of the two anti-slip ladders are respectively connected by protective chains; wherein, the lower ends of the two anti-slip ladders are hinged to the connecting pedal to make the protective hanging basket foldable.

[0005] In practice, there's also the issue of a fixed hanging basket depth. A worker who's shorter than the height of a construction site might not be able to reach welding points or formwork installation locations. Without a suitable hanging basket, construction workers often resort to suspended ladders or non-slip steps to reach the required height, but this places high demands on workers and creates safety risks.
