Learn concrete construction suspended slab and beams – method of construction step-by-step in 3D.
Columns:
Erect scaffolding for beams and slab shutter support.
Ensure to check the level difference between beam bottom and slab.
Make sure that base jacks have been provided for level adjustment in case of discrepancies.
Shutter fixing:
Brace the Columns and provide shutters for the remaining column height up to beam level.
Make sure the top of the concrete column is roughened (Chipped)
Provide Edge protection for safety.
Provide cover blocks for slab and beams.
Fix the beam reinforcements Anchored into the columns
Check reinforcement size and number as per design schedule
Bottom reinforcement to be lapped within 1/3 beam span from supports only
Check clear cover at beam bottom as well as the sides
Top reinforcement. Lap within midspan only (Lap at positive moment only)
Check stirrups spacing.
Check the corner intersection of beams and column if not congested. Ensure aggregates may pass through during concrete pouring.
Fix slab bottom bars. Arrangement shall be short span at the bottom and longer span above the short span.
Check clean spacing of reinforcement from shutter
Proceed with installation of plumbing sleeves and electrical services.
Fix top reinforcement. Long span to be laid first and short span to be laid over.
