Worked Solution & Example Answer:An open fireplace is located on the party wall between two semi-detached houses, as shown in the accompanying sketch - Leaving Cert Construction Studies - Question 1 - 2008
Step 1
To a scale of 1:5, draw a vertical section through the ground floor, hearth and fireplace.
Answer
-
Start by establishing the scale of your drawing. Ensure that all dimensions on your drawing are scaled appropriately according to 1:5.
-
Begin with the foundation. Draw a horizontal line representing the base of the fireplace graphically demonstrating the foundation beneath the structure.
-
Add the 300 mm thick party wall, marking the two semi-detached houses to either side. Show any relevant materials such as blocks.
-
Illustrate the fireplace section starting from the foundation level and moving upwards. Include the hearth and the position of the fireplace flue.
-
Add detailed elements such as the firebox, hearth, and chimney components.
-
Carefully incorporate four dimensions at appropriate locations within your drawing to demonstrate crucial measurements, such as the height of the hearth, depth of the fireplace, thickness of walls, and dimensions of the flue liner.
-
Ensure everything is drawn accurately to scale and is clearly labeled.
Step 2
Indicate clearly on the drawing how the flue liners are joined to ensure the safe removal of smoke and gases from the fireplace.
Answer
-
Clearly depict the junction where flue liners connect to the fireplace and chimney structure. Use dashed lines or arrows to denote the direction of smoke.
-
Indicate the types of joints used, such as collar joints or flexible connectors to show flue liner attachment methods.
-
Add annotations to the drawing to describe materials used for connections (e.g., clay, metal) and any sealing methods (e.g., gasket or caulking) to ensure no leakage.
-
Highlight any clearance distances from combustible materials as per building regulations to ensure safe operation.
