This is the tenth video in the series on the Timber Framing Code. This video looks at where we need to place our Hanging Beams now that we know our Ceiling joist spans. Hanging beams carry only roof loads

Really helpful videos. Appreciated. Can you please tell why have you put small timber pieces(timmers/outriggers) over top plates? Is the spacing of Joists 600mm as the rafter spacing? Thankyou.

@Buildsum 7 лет назад

HI Zeeshan The small pieces on the hip end are to carry the ceiling sheets and not interfere with the rafters at the hip end of the roof. Yes ceiling joists are spaced at the same spacing as the rafters. Thanks for your comments hope this helps

Good videos mate! My understanding of the maximum continuous span is kind of different. Like if you use the hanger, the continuous span of one of the room on the left bottom should be 3.5 rather than you said 1.7m which is excessed of maximum 2.2m. Is there something wrong of my understanding of the continuous span ? Thanks!

@Buildsum 6 лет назад

Hi Mate, for the room at the bottom left the Single Span would be 3.5m however, by adding the Hanger the required Continuous span becomes 1.750m while we could go all the way up to 2.2m in this situation

Great videos, really glad youre showing us these videos. i am curious as to why you had 2 of the rooms ceiling joists running perpendicular to the rest of the rooms. Was there a reason you did it or was it simply for exercise purposes? thanks

@Buildsum 8 лет назад

+Josif Nguyen Hi Josif It was mainly done for exercise purposes however it is possible. The Timber Framing Code state "ceiling joists shall be in single lengths or spliced in accordance with Clause 7.2.4.2, and at the same spacing and in the same direction as the main rafters so that they may be fixed to, and act as ties between, the feet of pairs of opposing rafters" The joists in the example fall under the hip and and therefor would not tie the main rafters. Also by turning them the span is shorter for the joists. Hope this helps

Yes it does, much appreciated.

Great Video mate! Just wondering if you can address me that 1.7 m and 2.2 m ceiling joist spans in AS 1684? Thanks

Hi Al, as the span tables are part of AS 1684.2 I can't give you a copy, however, there are plenty of free versions around. This page has a pretty good list of span tables and software that can help you work out the span you need. www.woodsolutions.com.au/articles/span-tables-and-software The other option would be to go to your local TAFE library ( if you are a student) or your local council library.

I have the span tables in office but never used them, mostly bcuz we use Hyne software. Just wanted to see if there is a rule that you said it's based on the span tables.

@Buildsum 6 лет назад

Hi, AS 1684 sets out general rules for the use and installation of the timber members and also tells us the correct span table that we should be using. So for this video I used the Span Tables for MGP10 timber in the N3 wind zone so those figures ( 1700 - 2200) come from that set of span tables, each timber grade and species have a separate set of span tables so it will depend on the timber you intend to use
