Constructing Logbook Week 9 Jiawei CHEN
Studio Activities Figure 1 shows the compression joint in the brick wall. Since bricks tend to expand due to their property, compression joint must be installed to prevent the crack in the wall due to the expansion of the bricks. The compression joint reacts to the compression forces from the bricks` expansion. The reaction force from the compression joint prevents the bricks from joining together.(Please refer to Figure 1.1) .Besides, the sealant in the compression joint prevent the moisture from seeping into the building.

Studio Activities Ê Figure 2 shows weep hole on the
brick veneer wall, which helps to remove the moisture from the building.
Figure 3 presents the detail of an additional part of box gutter in the brick veneer wall in the oval pavilion. The hole in wall is to prevent the water from seeping into the building when the box gutter filled with water. (Please refer to Figure 3.1)

Studio Activities Ê Figure 4 shows the comparison of different ways installation of the same material in
different contexts. The image on the left shows that timber floor, which is exposed to the sun and rain. The timber floor is joined by screw. However, the timber installed in the canopy, is joined by glue. This is because due to the convenience of maintenance and replacement of material. Since the timber used in the canopy is not exposed to rainwater and sunlight, timber is joined together by glue. However, the timber used for the flooring is exposed direct to the sun and rain. Therefore, the material needs to be replaced. Joining by screw for the flooring is relatively a easier way in terms of replacement of materials and maintenance. Figure 4
Studio Activities Ê This is the East elevation of
Wilson Hall. (Please refer to Figure 5). The material used for the window framing is steel. The steel window framing helps to protect the window as well as the aesthetic view of the building.
Figure 5
Ê The main load bearing members
are the columns behind the steel window framing rather than the windows in the east elevation. (Please refer to Figure 6).

CONSTRUCTION DETAILING:
•
Composite Materials:
it is about how materials are put together in any construction object -‐ Movement joints: compressed; as installed; elongated -‐ Health & Safety: -‐ Ageing gracefully: -‐ Repairable surfaces and resistance to damage -‐ Cleanable surfaces: • Butt cove for resilient flooring • Straight base for carpeted floors • Top set cove for any flooring type • Cove and cap strips - Maintenance access - Constructability: • Easy to assemble • Forgiving some little inaccuracy and minor mistakes • Efficient use of construction facilities, tools & labor - Other considerations: • Off the shelf items • Detailing to suit construction expertise -‐
Monolithic materials: • a single material, or • Materials combined so that components are indistinguishable (e.g. metal alloys) • Composite materials: • Two or more materials are combined in such a way that the individual materials remain easily distinguishable A composite is formed from a: 1. Combination of materials which differ in composition or form 2. Remain bonded together 3. Retain their identities and properties 4. Act together to provide improved specific or synergistic characteristics not obtainable by any of the original components u Main types of composite materials: (Fibrous; laminar; particulate; hybrid-‐-‐-‐combinations of two or more composite types)
• •
Sandwich Panel:
Glossary
A composite material that is made of timber and steel. (Please refer to Figure 7.) (Newton, 2014).
• Bending: a combination of compressive and tension developed at cross section of a structural member to resist a transverse force. (Ching, 2013).
•
Skirting:
•
Composite beam:
•
Shadow line joint:
a border, esp of wood or tiles, fixed round the base of an interior wall to protect it from kicks, dirt, etc. (Collinsdictionary.com, 2014).
Beam that is made of composite materials. (Newton, 2014).
• Cornice: “ a molded projection that crowns a wall or divides it horizontally for compositional purposes.” (Please refer to Figure x) (Ching, 2013).
