Small two tier split levels deck with connecting
staircase gets underway, with the installation of timber joists -
150x50mm (6x2in). The basic structure for the staircase is the first job
to do in order to allow ease of access between the split level decks.
In this case - with the deck being constructed over
a solid concrete pad/patio, there was no need to support the joists
other than to have 'pads' at 1m centres.
There is always the possibility of a 'rattle' on the
deck surface with this method of simply laying the joists down
unanchored. However, by using good quality joists - 6x2in and heavy duty
deck boards - 150x37mm - the risk of this is considerably reduced as the
sheer weight of the timber will act as a stabilising factor. |
