Worked Solution & Example Answer:A front porch with a tiled roof is shown in the sketch - Leaving Cert Construction Studies - Question 1 - 2015
Step 1
To a scale of 1:5, draw a vertical section through one half of the roof of the porch, to show one rafter length.
Answer
-
Draw the Vertical Section: Begin by drawing a vertical section of the porch, indicating the rafter and its slope of 30°.
-
Indicate Dimensions: Specify the internal width of the porch as 2.0 m, ensuring the axis of the rafter aligns accordingly.
-
Construction Details: Detail the construction elements including the 400 mm concrete block wall, the full-fill insulated cavity, and the insulated plasterboard beneath the ceiling joists.
-
Show Materials: Add notes indicating the materials used for each component as seen in the marking scheme.
-
Tile Courses: Above the eaves, depict three courses of tiles, ensuring to show the overall structure and dimensions clearly.
-
Label Dimensions: Include four critical dimensions in the drawing for clarity, following typical specifications from the marking scheme.
Step 2
On your drawing, show clearly one method of securing the wallplate to external wall.
Answer
To show a method of securing the wallplate:
-
Drawing the Securing Method: Illustrate the wallplate on the external wall and depict it fixed using L-shaped stainless steel straps.
-
Indicate Connection Points: Clearly mark the connection points of the L-shaped steel straps to both the wall and the wallplate, ensuring that these features are visible in the draft.
-
Label the Fixings: Include specifications for the materials, such as dimensions for the straps, if applicable, and describe their importance in ensuring structural integrity.
