Landscape&Municipal Construction:Applied to the reinforcement of round concrete columns in landscape engineering,municipal greening,square construction,such as landscape columns,street lamp columns,guardrail columns,with small size and flexible adjustment.
Installation&Operation Guidelines
Pre-Construction Preparation:Inspect the Column Formwork Clamp for deformation,cracks,rust damage or loose locking components before use;prepare the corresponding number of clamps according to the column size and construction requirements,and ensure the formwork is assembled in place,the edges are aligned and the gaps are tight.
Clamp Placement:According to the column shape(square/rectangular/round),place the corresponding formwork clamp on the outside of the formwork,ensure the clamp is closely attached to the formwork surface,the four corners of the square/rectangular column are fully covered,and the arc surface of the round column is closely fitted.
Adjustment&Locking:Adjust the clamp to the matching size according to the actual column specification,insert the wedge pin or lock the hoop,and hammer the locking component firmly with a rubber hammer to ensure the clamp is locked and fixed,with no looseness or displacement.
Spacing Arrangement:Set the vertical spacing of the clamps according to the concrete pouring height and pressure,the bottom of the column(0-1.5m)is densely arranged with a spacing of 300-400mm,the upper part is sparsely arranged with a spacing of 400-600mm,and the spacing can be appropriately adjusted according to the heavy-duty or light-load scenario.
Post-Installation Inspection:After the reinforcement is completed,check the tightness of all clamps and the verticality of the formwork,adjust the loose clamps in time,and ensure that the entire formwork system is stable and firm before concrete pouring.
Disassembly&Storage:After the concrete reaches the specified strength(generally 24-48 hours),remove the clamps in reverse order of installation,clean the concrete residue on the surface of the clamps,and store them in a dry and ventilated place to avoid rust,which is convenient for the next use.
Safety&Maintenance Notes
Strictly Abide by Load Capacity:Do not use the clamp beyond the rated load-bearing capacity and applicable column size range,and do not arbitrarily increase the spacing between clamps to avoid formwork deformation caused by insufficient clamping force.
Forbid Damaged Use:Do not use clamps with serious deformation,cracks,broken locking components or falling off anti-corrosion coating,and replace the damaged clamps in time to eliminate construction safety hazards.
Standard Construction Operation:During concrete pouring and vibration,avoid violent collision of the formwork and clamps with construction machinery,and check the clamp tightness at any time;if loosening is found,stop pouring immediately and reinforce it.
Regular Maintenance&Upkeep:Clean the clamps in time after each use,remove the concrete residue and dust;apply anti-rust oil to the pin holes and locking components regularly for maintenance;store the clamps in a dry and ventilated place,avoid stacking in the open air for a long time,and prevent rain and moisture.
Professional Operation:The installation and disassembly of the clamps shall be operated by professional construction personnel,and the construction personnel shall wear corresponding protective equipment to ensure personal safety during operation.
