Worked Solution & Example Answer:A four-panel wooden door is fixed in the external wall of a two storey timber-frame house, as shown in the sketch - Leaving Cert Construction Studies - Question 7 - 2007
Step 1
To a scale of 1:10, draw a vertical section through the external wall, door and floor joists.
Answer
To prepare a vertical section drawing at a scale of 1:10, start by marking the external wall, which consists of a concrete block outer leaf followed by a rendered finish. Below the head of the door frame at the height of 400 mm, illustrate the door frame and the door itself. Extend the section 400 mm above the first floor joists, including the joists and how they are connected to the external wall. Label the external wall construction detailing components like sheathing and internal lining materials. Additionally, include dimensions for the four main structural members, ensuring correct representation of sizes such as joist dimensions (e.g., 225 mm x 50 mm).
Step 2
On the drawing, show clearly how the first floor joists are supported at the timber-frame inner leaf of the external wall.
Answer
In the drawing, illustrate the support of the first floor joists at the timber-frame inner leaf. This includes a detail showing the joists resting on a solid upper plate connected to the timber inner leaf. Here, indicate the placement of vertical studs, and ensure proper labeling of components such as the 50 mm x 50 mm sole plate that supports the joists. Make sure to illustrate the position and connection methods clearly to demonstrate how they integrate within the wall structure.
