Worked Solution & Example Answer:The main door of a house is an insulated wooden door with 12 mm cedar sheeting on both sides, as shown - Leaving Cert Construction Studies - Question 1 - 2017
Step 1
To a scale of 1:5 draw a vertical section through the top of the door
Answer
- Begin by marking the base of the wall at a height of 400 mm from the ground level.
- Draw the vertical section of the concrete block wall (400 mm thickness) extending 400 mm above the lintels.
- Indicate the construction of concrete lintels above the door. The lintels are typically reinforced for added strength.
- Draw the doorframe dimensions (150 mm × 70 mm) and the door itself with a thickness of 90 mm, illustrating the insulated wooden door with 12 mm cedar sheeting on both sides.
- Ensure to include dimensions indicating heights of the doorframe, door, and lintels clearly.
- Label all components for clarity, ensuring it aligns with the marking scheme and their specifications.
Step 2
Show clearly on your drawing how to prevent the penetration of rainwater at the head of the door
Answer
- Insert a Damp Proof Course (DPC) between the inner and outer leaf of the wall at the head of the door to prevent moisture penetration.
- Illustrate the DPC sloping towards the outside to ensure effective drainage of rainwater away from the door.
- Include an additional detail indicating the waterproofing measures, ensuring the continuity of the DPC across the entire width of the doorframe.
