Note: All Any of the framing wood. should be suitable for exterior use and any lumber either touching the ground or going into the ground should be suitable for inground applications.
Also called a ledger The top or bottom horizontal framing member of the wall.. The stringer is the piece of lumber bolted to the house upon which the joists are fixed on or to. The stringer needs to be packed out from the building at every A metal rod that has a head on one end and threads on the other and is used to fasten together lumber. The most common bolts used or referred to in projects within this website are coach/carriage bolts and hex bolts. fixing to prevent moisture being trapped between the stringer and the building. The spacing between the bolts depends on the size of the stringer and the The horizontal distance between supporting structures. of the joists which are fixed on or to it.
example: If a stringer is 100×50 (2×4) in size and if the joists fixed to that stringer span 2m (80″), the bolts that attach the stringer to the building should be 1.25m (50″) apart, where as if the joists span 6m (20ft), the bolts should be 0.5m (20″) apart.
A standard A base (in or on the ground) that will support the structure. hole size for 100×100 (4×4) or 125×125 (5×5) see PILE is 300mm x 300mm (12×12) square and 450mm (18″) deep in firm ground. In soft ground the holes will need to be bigger and deeper. Also holes will need to be deeper in ‘frost’ areas. 100mm (4″) of A mixture of sand, gravel, water and cement which hardens to a stone like condition when dry. is required as a pad beneath the post.
POSTS are Usually at least 100×100 (4×4). The spacing of posts along the A sub-floor wood supporting the floor joists. line depends on the structure of the A flat floored roofless area adjoining a house. Timber deck: An outside floor structure comprising of posts, bearers, joists and decking boards..
The size of the bearer depends on the length of the joists and the span of the bearer.
The joists are fixed to the stringer either by butting up to and fixing with One of a series of parallel members used to support the floor. Part of the framing that provides the structure for a floor. hangers, or by sitting on top of the ledger plate and nailing through both faces of the joist.
The joists sit on top of the bearer and are fixed by way of nailing through each The widest side of a piece of wood. of the joist into the bearer.
The size of the joists depend on the joist span and the joist spacing.
The thickness and strength of the various deck materials determines how far apart the joists must be.
7) Boundary joist
The boundary joist is fixed to the boundary. of the deck to give a neat finish. In most cases the boundary joist is decorative rather than structural, therefore another preference might be to replace the boundary joists with decking boards.
