Week 9 Journal: Last week, we explored the roof which was the project in assignment 2. The 1:1 scale model was made by some students and tutors. They showed and analysised details of roof. The whole was timber frame structure. We could see the load bearing beam and supporting column clearly. Also, It showed the rafters. The whole material was timber. Such as this laminated timber.
It was load bearing beam. It could support the rafters.
The supporting column which was made by laminated timber and it was the core to load the force from roof. In addition, the whole structure used bolted joint to connect each section. “This is typically accomplished by using a threaded hole that sinks through one object and into the next. A bolt then screws down into the hole and connects the pieces together. This connection is exceptionally strong, much more so than other common forms of connection (McGee, 2013). �
Then, we began the second activity---the presentation of the part of building. I introduced the structure and details of section12 in Ormand college. After that, tutor leaded us to draw the 3D image of case study building detail.
The left one is the part section of Ormand college and the right one is 3D image. This is a 3D model, it was made by glass and plastic.This section could resist the heat flow through the roof.
Waterproofing: in this section, it uses flashing to prevent passage of water into a structure from an angle or a joint(Ching, 2008). Also, it has a weep hole which is used in the render and the block work to allow for any potential water and moisture(Ching,2008). Economic implication of decision: The building uses glass as its frame, aluminum sill and plastic. These materials are not too expensive to get, but these are necessary for thermal insulation. Sustainability: Using aluminum is not really sustainable, because it can release relative high amount of carbon emission. However, it is necessary for windows to hold the weight. Pros and cons: The pro of the window is that it can collect the light from outside and make house become much brighter. It can save the electricity and it is an useful installation to achieve sustainability. The cons is that the window is sealed, so it can’t get fresh air.
