Worked Solution & Example Answer:A non load-bearing timber stud partition, with plasterboard on both sides, separates a kitchen and living room, as shown in the sketch - Leaving Cert Construction Studies - Question 4 - 2014
Step 1
Using notes and freehand sketches show the typical construction details of the timber stud partition. Name the main components and give their typical dimensions.
Answer
The typical construction details of a non-load bearing timber stud partition include the following components with their dimensions:
- Sole Plate or Baseplate: Dimensions of 75 mm x 50 mm or 100 mm x 50 mm.
- Studs: Standard size of 75 mm x 50 mm or 100 mm x 50 mm, spaced at 400 mm centers.
- Nogging or Bridging: Size of 75 mm x 50 mm or 100 mm x 50 mm.
- Head Plate: Similar dimensions to sole plate (75 mm x 50 mm or 100 mm x 50 mm).
- Fixing Plate for Electrical Services: Often 100 mm x 50 mm.
- Insulation: Fitted between studs.
- Plasterboard: Standard size considered is 2400 mm x 1200 mm x 12.5 mm, fixed to studs with coated nails or screws.
- Plaster Skim: Generally applied to both sides of the plasterboard.
Step 2
Show one method of fixing a double electrical socket in the stud partition.
Answer
To fix a double electrical socket in the stud partition:
- Locate the Position: Determine the location of the socket on the timber studs.
- Fit the Fixing Batten: Attach the fixing batten between the studs, aligned with the edge of the socket box.
- Position the Socket Box: Ensure the front of the gang box is flush with the front edge of the fixing batten.
- Mark the Position: Outline the position of the socket on the plasterboard.
- Cut Out Opening: Use a pad or plasterboard saw to cut the outlined area.
- Connect and Insert Socket: Fix the socket box to the fixing batten and tighten screws. Ensure the side clips will grip the plasterboard as screws are tightened.
Step 3
Using notes and freehand sketches, show the steps involved in applying a plaster skim finish to one side of the stud partition.
Answer
To apply a plaster skim finish to the side of the stud partition:
- Prepare Area: Spread sheeting over the floor to protect it from plaster.
- Tape and Seal: Use tape to cover joints and seal the partition against walls and ceilings.
- Dampen Wall: Lightly moisten the wall using a large paintbrush.
- Mix Plaster: Always add plaster to water in a clean mixing bucket to avoid lumps. Use a mixer or hand mixer to ensure a smooth consistency.
- Application: Use swift strokes to apply the plaster uniformly, ensuring a thickness of 1 to 2 mm.
- Level Surface: Once applied, level and smooth the surface while the plaster is still soft.
- Final Touches: After the surface is even, leave it to set but not dry completely, then polish the surface.
- Cleaning Up: Wash the trowel and tools immediately after use.
