Description

Technical Field

[0001] This utility model relates to the field of performing arts building engineering equipment, and in particular to a heavy construction equipment for ultra-high, ultra-wide, and ultra-deep building spaces. Background Technology

[0002] Currently, full-span scaffolding is widely used for large-area indoor high-altitude operations. While a safe, reliable, and convenient working platform, its limitations are significant for large, heavy-duty structures with short work cycles. Taking the construction of the steel roof structure of the stage area within a performance venue as an example, long-term practice shows that the construction cycle of the steel roof structure is shorter than the erection and dismantling cycle of full-span scaffolding. Furthermore, the erection and dismantling of full-span scaffolding easily leads to idle work, thus affecting labor costs and the project construction cycle. In addition, depending on the scale of the performance venue, the steel roof structure itself has a certain height, and its structural characteristics require work at different heights above the full-span scaffolding. Therefore, layered work or setting up 1-2 layers of mobile scaffolding on the full-span scaffolding may be necessary, which introduces more safety hazards. Moreover, the steel roof structure in a performance venue of a certain size is generally constructed by cross-laying 18# I-beams, and the transportation and high-level installation of these 18# I-beams on full-span scaffolding presents significant work difficulties. Therefore, using full-span scaffolding to construct equipment with similar grid-top steel structures is not only inconvenient and introduces more sources of risk, but also has a very low cost-effectiveness.
