Description

Technical Field

[0001] This utility model belongs to the field of bridge construction equipment, and specifically relates to a combined operating platform suitable for multiple variable cross sections. Background Technology

[0002] During bridge construction, temporary structures such as piers, scaffolding, and ladder cages are required to support the erection of formwork or beams. This is typically achieved using spliced ​​scaffolding and ladder cages. This method requires a large quantity of scaffolding pipes and necessitates climbing between different scaffolding levels using long ladder cages, making safety and stability difficult to guarantee. Furthermore, when the installation involves complex situations where the cross-sectional area varies across multiple heights, the limited space further complicates the erection of scaffolding and ladder cages, making the structure more unstable and posing greater safety hazards.

[0003] Patent document with application number "201920091714.6" discloses a banana-shaped bridge construction device, including scaffolding, an adjustable base, and a construction platform. The scaffolding is installed on the adjustable base, and protective netting is installed around the scaffolding and hooked onto the scaffolding. Ladders are installed inside the scaffolding, and the scaffolding is symmetrically arranged on the left and right sides of the adjustable base. The construction platform is set between the scaffolding sections and is located above the ladders, allowing workers to access the construction platform via the ladders. Although this embodiment uses ladders instead of ladder cages for climbing between levels, the overall scaffolding still adopts a regular structure with a uniform cross-sectional area, which is not suitable for complex situations with multiple heights and different cross-sectional areas. Furthermore, the scaffolding sections are connected by bolts, posing structural and strength safety hazards, and the material consumption is relatively large.
