place trusses

We began to set up trusses two weeks ago,I'll write how to do it in sequence.

Steps to set up trusses:
1.Erecting scaffolding;
2.Trusses are delivered to site,hang them on top plate in correct order,bracing them on the floor temporarily;
3.Reading the plan of setting up trusses;
4.Marking trusses space;
5.Position gable end truss.Mark centre of building width, also mark centre of bottom cord. These two marks will align the truss to the centre position.Temporary brace and plumb both gable trusses
6.String a line between the two apexes,one is the front,another is the second truss from back;
7.Position intermediate ( common ) trusses.Position each truss according to the markings along the top plates,align the apex of each truss with the string line ( gable-gable );
8. Nail ceiling runner at the centre along these trusses and fix brace on both gable trusses.
9.Fix purlins on the trusses.150mm from the apex to the lower side,spacing is 600 mm and 500 mm.The lowest is flush with the edge of rafter;
10.Fix outriggers to gable trusses and fix fly rafters to outriggers;

Scaffolding and trusses

Last two weeks,we have tacked double top plate on the top plate and put ceiling batten on.
First,we tacked double top plate on external wall framing,2 nails / 400 mm,then we put one edge of ceiling batten in the double top plate,another edge of ceiling batten is on internal wall framing from building's back to the front,the ceiling batten's space is 330 mm. we also put double top plate(short)on internal wall between ceiling batten.

we spent a lot of time on erecting scaffolding last week.I think it's worth.Spending more time,means making it stable and safety for us in the future.We have known Right angle coupling,swiveling coupling,jointer etc scaffolding connector and learned how to erect scaffolding,how to make it firm.

we began to tack trusses last week,about this section,I'll write next week.
