1st day term 2

1st day back from the hoilidays we started on making the bbq table toni and i had 2 find out the angles of the legs by doing some calculations and the other 3 groups were conserntrating on something else

Roof


A roof is the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather. Structures that require roofs range from a letter box to a cathedral or stadium, dwellings being the most numerous.
In most countries a roof protects primarily against rain. Depending upon the nature of the building, the roof may also protect against heat, sunlight, cold, snow and wind. Other types of structure, for example, a garden conservatory, might use roofing that protects against cold, wind and rain but admits light. A verandah may be roofed with material that protects against sunlight but admits the other elements.

Insulation

Building insulation refers broadly to any object in a building used as insulation for any purpose. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. for vibrations caused by industrial applications). Often an insulation material will be chosen for its ability to perform several of these functions at once.

Cladding

Corrugate profile is a traditionally styled roofing and cladding sheet. Corrugated roofing's low material cost and rapid installation places it amongst the most economical products of its type available. Corrugated roofing is machine-rollable to minimum inside radius curves of 400mm for (eg) barrel ridges, horizontally-clad wall corners and bullnosing. Corrugated roofing has a variety of coatings, including natural galvanising and powder-coated process finishes, are available to suit environmental and aesthetic criteria.

flashings

To make your project stand out from the rest you have to come up with something a little bit different. Dimond can help through their ability to curve their roofing and cladding profiles in several different ways. If you are simply looking to add a gentle curve to your roof then many of Dimond’s profiles can be drape curved as shown in the picture above. If you are looking to add a bold edge to the eaves of your design or break up the look of a long roof then crimp curving one of Dimond’s profiles is your solution. Pak’n’Save supermarkets have successfully used crimp curving on many of their stores in an attempt to gain that eye-catching and memorable look. And if you want to create a more rounded curve then we can pre-curve Corrugate to a minimum radius of 450mm depending on the material type and thickness.

Flashing refer to thin continuous pieces of sheet metal or other impervious material installed to prevent the passage of water into a structure from an angle or joint. Flashing generally operates on the principle that, for water to penetrate a joint, it must work itself upward against the force of gravity or in the case of wind-driven rain, it would have to follow a tortuous path during which the driving force will be dissipated. Exterior building materials can be configured with a non-continuous profile to defeat water surface tension.
Flashing may be exposed or concealed. Exposed flashing is usually of a sheet metal, such as aluminium, copper, painted galvanized steel, stainless steel, zinc alloy, terne metal, lead or lead-coated copper. Metal flashing should be provided with expansion joints on long runs to prevent deformation of the metal sheets. The selected metal should not stain or be stained by adjacent materials or react chemically with them.

Types of fixings

ABOVE:   Top: Expanded metal lathing. This comes in sheets or rolls of varying widths from 2 inches to 12inches. Its primary use is for fixing to non pourus or in fact, non masonry, surfaces  in order to plaster or render them. The mesh, which is galvanised to avoid rust, is fixed securely to the structure and the plaster or render applied over it. For a demonstration, please see our projects page and go to the garden project, where this material formed the basis for our cave.

Bottom: Galvanised strap. One of the more versatile fixings in the trade. Can be used for fixing roof timbers in place, holding door frames to masonry, cut into washers, the list goes on.

ABOVE: Far left: A self tapping Ankerbolt. Drill the required diameter hole and screw it in with a spanner. Expensive, but very handy for a solid wall.

Centre: Screw eye. The same principle as a curtain hook or eye, but heavy duty ! Uses include tying the bottom of ladders to the wall and securing the top of ladders to the facia. A very safety minded weapon!

Top right:  A tingle, or disc rivet. Used for fixing the bottom of man made roofing slates so they are not lifted by the wind.

Bottom right: Black japanned screw: Japan is an extremely hard varnish used to protect the screw against the elements. For this reason, black japanned fixing are used in garden gate furniture etc.

ABOVE Nails: Left: "Wire nail", the universal nail with a medium head that comes in many sizes up to 6 inch. next is a "cut nail," cut from steel, its square section gives it a larger surface area and a better hold in soft masonry and mortar. This nail is also used as a "flooring brad" and is less likely to split wood.

Bracing

Types of Bracings Used in Construction

Wall bracing is a construction technique used to improve the structural performance of a building. Bracing systems include wood or steel components that help evenly distribute loads and increase the safety of the structure. While traditional framing can support the weight of the roof and floors above, it is not able to resist lateral stresses caused by wind, earthquakes or other forces. Bracing requirements are set by the International Residential Code Section 602, which have been adopted into the majority of building code

the past 2 weeks

the past 2 weeks we have put down floor insulation and fixed it therethen we sqweared up the floor boards and and nailed them in 150mm appart on the out side and 200mm appart nailing it 2 the floor joist. We have also got the back wall up we had 2 put some stops so it didnt slide of the back. Once we have put it were it is going to be we nailed tacks down and got a brace and made sure it was strate up with the leveler.We had 2 do the same drill will all of the walls. once all the walls were fixed down with the braces we string lined the end of the walls to make sure they were strate and the top if it was to hight we would have 2 put a smaller nog in. On monday we started on the roof

week 7

on monday we were starting on the side walls that tony and i did in a group of 2. We did it qwite well just being the 2 of us we had 2 cut all the studs with a 5 degree angle on it and differnt sized nogs. and the were 2 paccers.

week 7

on monday we string lined the boundery joice and cutted the studs for the back wall in the sleep out and also cut the back plate and frount plate.the bottem plate had to be 3.1.

on tuesday we layed down the frount plate and back plate and lined the studs up with the markings.
