Answer :

Techniques for Assembling and Fixing Stair Components
Assembling and fixing stair components requires precise techniques to ensure safety and durability. First, begin by cutting all components—stringers, treads, risers, and balusters—to their specified dimensions based on your design plans. Next, assemble the stringers by securing them to the floor or landing using brackets or screws to ensure they are level and stable.

Once the stringers are in place, attach treads using either screws or adhesive for added strength; ensure they are evenly spaced with consistent overhangs if required. For added stability, consider using step bolts or dowels to reinforce connections between treads and stringers.

 

Balusters should be installed next; secure them into pre-drilled holes in both the tread and handrail using glue and nails or screws. Ensure that each baluster is plumb before securing it completely.
Finally, install handrails by attaching them to newel posts or directly onto balusters using brackets or screws, ensuring they are at an appropriate height for safety. Regularly check all connections during assembly for tightness and alignment to maintain structural integrity throughout the staircase.

Q1: Discuss the two (2) types and two (2) uses of tools and equipment given in column 1 of the table required to construct and install timber external stairs.  

Answer :

Tools and equipment

Types

Uses

Nail gun

Pneumatic Nail Gun

Used for quickly driving nails into timber components, ensuring strong joints in stair construction.

Cordless Nail Gun

Provides portability and ease of use, allowing for efficient fastening without a power source.

 

Power saw

 

Circular Saw

 

Utilized for making straight cuts in timber, essential for cutting stringers and treads to size.

 

Miter Saw

 

Ideal for making angled cuts, particularly for joining stair components at precise angles.

 

Hammers

 

Claw Hammer

 

Commonly used for driving nails into timber and removing nails when necessary during assembly.

 

Framing Hammer

 

Heavier hammer used to drive larger nails, providing more force for securing structural components.
