Week 5 Journal 214 KG Our group makes a timber structure in the consturction workshop that is able to bear 214 KG!
Material we use: two 35mmX35mm timbers and one 18mmX45mm plywood
Using one 35mmX35mm timber beam to cut into six parts and then put each two together in the middle of the other two long timber beams. This structure is able to disperse the load from the top. The double small timbers are superposed so it is enough stable for point load. In this structure, we use some different size of nails to fixed the timber. And put the 18mmX45mm timber under the bottom which can make this structure stronger.
The double superposed small timbers. They are able to bear a larger point load from the top of them.
Firstly, we have a measure of the two 35mmX35mm in order to cut the right length. Then, we use hammer to allow two nails into double small timbers.
After that, using electric drill to drill three bigger and longer size joists into one 35mmX35mm timber in order to connect them.
Doing the same work on the another side.
We put the 18mmX40mm plywood under bottom and also use three longer nails to connect them. Before we hammer these nails, we measure and draw where the other nails inside the timber in order to avoid them. Finally we are done this work on time
Putting our model into a machine to measure how much weight it can bear. From the picture on the right hand side, the load is from the middle.
The model bears 214KG at the end. We can see the model broken the top and bottom timber broken where there are no double timber in the middle. The double timber on the right hand side separates because of the load. The top timber has more severe break than the bottom one because there is a plywood bear under the bottom of timber.
This is another group’s model. It is box beams timber structure. They use two pieces of plywood naturally define an axial and bidirectional space. Due to this plywood are perpendiculars that are not able to bear too much weight. Thus, they have broken away from the main timber first.
The drawing part Case Study Building Name: ERC Building From this drawing work, I know there are differences between plans, elevations, sections and details in drawing content. The information in the title block is important as well because this information allows people to know what this kind of drawing is about. For example, the first letter is A in the drawing number which is architecture drawing and otherwise it will be the other drawing such as engineering drawing.
There are lots of annotations in the plans of drawing content. These annotations have different meaning. For example the left annotation is the building section reference.
The areas of the drawing are clouded in the plan which means the drawing is clouded if there is revision or change to anything. This cloud helps to keep track of any changes.
