Improving the efficiency of setting up and dismantling mobile scaffolding requires optimizing processes, upgrading tools, and strengthening management while ensuring safety. Specific measures are as follows:
1、 Strategy for improving construction efficiency
Preparation for prefabrication and modularization
Complete component assembly on the ground in advance: pre assemble the upright and horizontal bars according to standard units (such as 1.8m × 1.2m), temporarily fix them with dedicated connectors, and reduce high-altitude splicing time; Classify and pack small components such as wheels and fasteners (indicate quantity and specifications) to avoid time-consuming on-site searches.
Standardized basic treatment: measure the flatness of the site in advance, lay prefabricated steel pads (size 500mm × 500mm × 10mm) uniformly on soft ground, and reduce the foundation adjustment time of a single set of scaffolding; Complex terrain can be prefabricated with adjustable bases (height adjustment range 0~300mm) for quick leveling.
Tools and Process Optimization
Adopting quick connect components: using snap on crossbars (instead of traditional bolt connections), achieving 3-second quick fixation through spring locking plates, and improving connection efficiency by 60%; Equipped with a rechargeable impact wrench (adjustable torque), the bolt tightening speed is three times faster than a manual wrench, and it avoids missed tightening.
Division of labor for assembly line operations: Divide into groups according to "foundation group → pole group → crossbar group → protection group", with 2-3 people in each group working synchronously (such as when laying base plates in the foundation group, the pole group synchronously assembles the lower frame) to reduce cross waiting time.
2、 Demolition efficiency improvement strategy
Component classification and rapid disassembly
Develop a "reverse assembly" dismantling sequence: disassemble in the order of "protective parts → scaffold board → crossbar → upright", and stack components in the same area (such as placing fasteners in dedicated storage bags and classifying and stacking upright and crossbar) to avoid secondary sorting.
Special disassembly tool: Use penetrant (sprayed 10 minutes in advance) to soften corroded bolts, and use a ratchet wrench to quickly loosen them; Adopting a detachable scaffold board (with quick locking), a single person can complete the removal of one scaffold board in 10 seconds, saving 50% of time compared to traditional binding methods.
Efficient transportation and stacking
Configure small transport equipment: Use a flat trolley with brakes (load capacity ≤ 500kg) to transport components in close proximity, or use a folding cage (in conjunction with a tower crane) for vertical transportation to avoid time-consuming manual handling; Long components (such as uprights) are neatly tied with strapping (every 5 pieces) to improve loading efficiency.
Real time on-site inventory: After dismantling, record the quantity of components synchronously (scan the code with a handheld terminal for registration) to avoid time-consuming inventory in the later stage and ensure that there are no missing components.
3、 Management guarantee measures
Advance planning and training
One hour before the installation/dismantling, a technical briefing should be conducted to clarify the tasks, time nodes, and safety points of each group (such as the locking confirmation method of quick connecting components), in order to avoid rework due to unskilled operation.
Regularly conduct skill training to enhance workers' proficiency in operating specialized tools and modular components, and shorten the time required for single process operations.
Equipment maintenance and spare parts reserve
Check the status of quick connectors, wrenches, and other tools daily to ensure they are not damaged; Reserve 10% of spare components (such as fasteners and wheels) to avoid downtime due to missing components.
Through the above measures, the efficiency of setting up/dismantling mobile scaffolding can be improved by 30% to 50%. At the same time, it should be noted that efficiency improvement must be based on safety, and it is strictly prohibited to omit protective measures or engage in illegal operations (such as setting up without fixing wheels, throwing components, etc.) in pursuit of speed.
