To quickly complete the construction and dismantling of mobile scaffolding, it is necessary to combine tool optimization, process simplification, and skillful operation, while strictly adhering to the safety bottom line. The following are specific practical tips:
1、 Build Quick Skills
Prefabricated assembly reduces high-altitude operations
Pre assembled unit frame on the ground: assemble the upright and cross bar into a "piece frame" on the ground according to the height of 2 layers (about 2.4m) (such as the frames on both sides of the double bent frame), fix them with temporary slant support and hoist them in place as a whole to avoid splicing one by one, which can save 40% of the assembly time.
Preparation for "Assembly of Components": Prepare the components in advance according to the installation height (such as 16 vertical poles, 32 horizontal poles, and 8 wheels required for a 12m frame), place them in layers using dedicated storage racks, label the quantity, and avoid repeated on-site counting.
Tool upgrade, accelerate connection fixation
Replace traditional bolt fasteners with quick locking fasteners: These fasteners are designed with spring buckles or eccentric wheels, and can be manually tightened after fastening (with anti slip force meeting standards), reducing the time required for a single connection from 30 seconds to 5 seconds.
Electric tool assistance: Equipped with a 12V rechargeable impact wrench (with torque limiting function), it does not require manual tightening when tightening bolts, increasing efficiency by three times and ensuring consistent torque (avoiding over loosening or over tightening).
One step basic processing
If the ground is slightly uneven, use an adjustable wheel seat (with a height adjustment range of 0-150mm) directly to replace the traditional pad and brick leveling. After adjustment, lock the brake immediately, saving time for repeated adjustment of paving and leveling.
Multi person collaborative division of labor: 2 people are responsible for pole positioning and wheel fixation, 2 people synchronously install horizontal bars (pushing from bottom to top in layers), and 1 person checks verticality (monitoring in real-time with a ruler, adjusting immediately when deviation exceeds the limit), forming a streamlined operation.
2、 Quick demolition techniques
Reverse disassembly, classification and collection
Dismantle in the reverse order of "protective parts → scaffold board → upper horizontal bar → lower horizontal bar → upright pole" to avoid cross operation jamming. The scaffold board adopts a "pull-out type" (loosening the fixed pins at both ends in advance), and a single person can remove 2 pieces at a time, which is 5 times faster than traditional bolt disassembly.
Components can be disassembled and stacked as needed: Three stacking areas (pole/crossbar area, fastener area, and small item area) should be set up next to the demolition area. After demolition, they can be directly classified and placed, eliminating the need for secondary sorting in the later stage. In particular, fasteners should be collected in dedicated mesh bags to avoid scattering.
Effortless transportation, reducing handling time
When dismantling to a height of 3 floors, temporarily place the removed long components (such as poles) horizontally on the remaining frame, accumulate 5-6 pieces, tie them with straps, and have 2 people lift them synchronously to the stacking area to avoid the waste of single piece transportation back and forth.
Using a "folding transport rack": The rack body is equipped with universal wheels, which can be directly pushed into the dismantling area. After the components are dismantled, they are immediately put on the rack, and after being filled, they are pushed away as a whole, which increases the efficiency by 60% compared to manual handling.
Skills for handling difficult points
Rapid loosening of corroded fasteners: Spray bolt loosening agent (such as WD-40) on the connection point 5 minutes in advance. When removing, gently tap the side of the fastener with a tapping wrench and use vibration to assist in loosening, avoiding tool damage caused by rough twisting.
When the height exceeds 6m, dismantle it to below 6m before continuing: reduce the time for high-altitude operations and minimize the risk of component falling. During the dismantling process, maintain the stability of the frame (check the verticality every 2 floors).
3、 General principle of efficiency
Three inspections to save rework: during construction, check the verticality (quickly calibrated with a laser projector), fastener locking, and scaffold board fixation every 2 layers completed; Before dismantling, check that there are no residual loads on the frame and no obstacles on the ground to avoid rework due to omissions.
Small team collaboration: 3-4 people in groups (1 person commanding+2 people operating+1 person assisting), with clear areas of responsibility for each person (such as left vertical pole, right horizontal pole), synchronized actions (such as installing horizontal poles on both sides of the same floor at the same time), reducing waiting time.
These techniques can increase the efficiency of building/dismantling by more than 50%, but it should be noted that all quick operations must be based on safety, such as not loading the wheel brake without locking it, and strictly prohibiting throwing components during dismantling to ensure "fast and safe" operation.
