Worked Solution & Example Answer:A non load-bearing stud partition separates two upstairs bedrooms in a dwelling house - Leaving Cert Construction Studies - Question 5 - 2013
Step 1
Draw the vertical section through the stud partition and the floor
Answer
-
Start by establishing a horizontal baseline representing the finished floor level.
-
Indicate a level line 400 mm above the finished floor level to mark the height of the partition.
-
Draw the stud partition with a width between 63 mm and 100 mm (specifically use 70 mm to remain within the standard).
-
Illustrate the 215 mm solid block wall as the structural support at the base of the partition.
-
Above the block wall, detail the 200 mm x 50 mm joists, ensuring proper spacing and alignment.
-
Show the floating floor structure, starting with a layer of plywood (25 mm), followed by the floating tongued and grooved oak timber floor.
-
Add the 12.5 mm plasterboard ceiling, ensuring it is attached to the underside of the joists.
-
Include a polyethylene bubble underlay beneath the floorboards for insulation.
-
Lastly, add three typical dimensions, such as: the height to the ceiling, width of the partition, and total height of the wall, clearly indicated on the drawing.
Step 2
Show the typical construction details from a level 300 mm below the plasterboard ceiling
Answer
-
From the 300 mm below ceiling line, draw the plasterboard layer, maintaining the 12.5 mm thickness.
-
Continue down to mark the insulation placed between joists, showing a thickness of 150 mm.
-
Illustrate the vapour barrier, which should be depicted between the insulation and the plywood.
-
Clearly identify the joists supporting the floor (200 mm x 50 mm), with adequate spacing illustrated.
-
Indicate the 120 mm skirting board around the perimeter of the room.
-
Finish by marking the overall dimensions of the solid block wall (215 mm), highlighting its structural role.
