Robert Clark Posted June 2, 2021 Share Posted June 2, 2021 Hi Guys Our builder is assembling our oak framed extension. He appears to be having issues getting the frame square to the dwarf walls and has fixed the bottom beam to the wall with some bolts whilst he completes the assembly. I’m wondering if it would be better to remove the bolts after the assembly is complete, to enable the frame to move as it desires? Im concerned that if the bolts are left in place that the frame may cause the bricks to crack and / or dislodge over time. Appreciate any comments Thanks Link to comment Share on other sites More sharing options...
Mr Punter Posted June 2, 2021 Share Posted June 2, 2021 With a standard softwood timber frame it is always mechanically fixed down to stop it moving. Did the oak frame come with a specification covering this? Link to comment Share on other sites More sharing options...

Mr Punter Posted June 2, 2021 Share Posted June 2, 2021 What do Building Control say? They would normally insist on a full specification plus structural calcs. Link to comment Share on other sites More sharing options...
Robert Clark Posted June 2, 2021 Author Share Posted June 2, 2021 The builder has gone back to the structural engineer as there is no detail in the plans for this item. Link to comment Share on other sites More sharing options...
JFDIY Posted June 2, 2021 Share Posted June 2, 2021 My full Oak frame (11m X 5.5m by 1.1/2 story) isn't bolted down, just rests on the dwarf wall, they used hi-load DPC as it's thicker and rubberised to account for brickwork height variance plus I guess it helps with increased friction to sideways loads. 1 Link to comment Share on other sites More sharing options...
Temp Posted June 2, 2021 Share Posted June 2, 2021 We have some oak posts holding up roof overhangs and the like. We used stainless steel pins to locate the bottom of the posts on plinths. That were cemented into the plinth with about 6" sticking up into holes drilled in the bottom of the posts. 1 Link to comment Share on other sites More sharing options...
tonyshouse Posted June 3, 2021 Share Posted June 3, 2021 I like to hold posts up off anything that they can sit on outdoors, eg plate rebated into the end of the post 2 Link to comment Share on other sites More sharing options...
Jckay21 Posted September 15, 2021 Share Posted September 15, 2021 It's the extension faced with glass or encapsulated? Link to comment Share on other sites More sharing options...
