Browse Forums General Discussion 1 Nov 06, 2015 10:33 pm My house's timber subfloor is currently being done. I noticed they connect all the joists together with pieces of timber between the joists, not continuous trimming edge. Im wondering is there any difference between the 2 methods. my gut feels that the continuous trimming edge look strong. am I right? Re: what is a good way to tie timber joist together. 2Nov 07, 2015 8:52 am it really depends: If the joist is supported between bearers, or brickwork it is better if the joist sits fully on the support (and blocks are used. see http://anewhouse.com.au/2014/04/types-of-floor-joists/) If the joists cantilever out over a balcony then a continuous trimming edge is better (and neater) The Harder You Try - the Luckier You Get !

Re: what is a good way to tie timber joist together. 3Nov 07, 2015 9:07 am Hi chuminh You will need to provide photos (in context) so they can be checked against the codes for compliance. If the details are non-compliant then they will need to be certified as equivalent or better by a Structural Engineer.

I believe they use the HY joist as said in the website provided bashworth.

In the third photo, the joists span about 5, 6 meters. There is no brick piers to support the bearers which supports the joists. it shakes when I try to move it. Im not sure if it is strong enough as that location is the bedroom. The rest of the joists seems strong though. Re: what is a good way to tie timber joist together. 5Nov 09, 2015 10:13 am Judging from the photos (and there are a number of issues) I would say there appears to be set out issues and that all the piers weren't built at the same height to support the floor bearers/joists etc? There are also temporary timber props supporting the bearers which also supports (no pun intended) my above claim. You will need to have them properly inspected, do you have the engineering Drawings for starters? Then you will need to check pier heights, bearing, supports, spans, etc against the codes for compliance Residential timber framed constructions AS1684. Either you or your builder can check for compliance in the codes...remember if it is non-compliant then you will require an engineer (Footnote: this is a big problem with the industry nowadays, to achieve scales of economies trades are very specialised, quick and cost effective, that is until something goes wrong or the previous trade S%$%^- up.. then the work becomes expensive, time consuming to fix & no one takes responsibility) Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: what is a good way to tie timber joist together. 6Nov 10, 2015 12:18 am I checked today and saw that they inserted a thinner piece of brick to support the bearers. Look like it is fine. Im not sure if the quality is compliant as this supposed to be checked by the site manager. I believe the engineers designed this floor system is Intrax. Should I contact them or the site manager? Site manager doesn't tell me anything. Im not sure if he comes to the site to check. I have a look at the codes for compliance. should I talk to the site manager? How do I know if the surveyor comes and checks my site? Thanks Re: what is a good way to tie timber joist together. 7Nov 10, 2015 12:31 am I can't find infos regarding to the timber joists. I guess it is fine as I dont know about these stuffs and dont know how to ask the questions. Assuming you've modelled the TB8, TB10, TB12, TB2 & J1 joists/LVLs there, it appears as per drawing to me. There maybe should be an additional J1 between TB10 and T12 if… 3 27642 Seconded; we just used these last weekend to build a small deck.
