rsj

Hi, New here. Need some advice on a project I’m working on. Iv had a 5meter RSJ put in across the back of my house. I have some bifolds ready to go in for now but In 6-8 months time I am having an extension. When I do the bifolds will move to the new extension. The problem is the RSJ...

Universal Beam 1.8m length 1.46 opening in single leaf wall. Supporting walls are 350mm and 400mm wide. SE has specified 3 courses of blue bricks rather than a padstone. Do I get the brickie to lay the 3 courses in normal brick pattern, or are they stacked one on top of the other? Given...

Hi, we're doing up a stone house, and have lots of vapour-related potential problems. Today's problem: we have an RSJ across a room, both ends in external stone walls, supporting the first floor joists. We're installing internal insulation (stud etc.) on all external walls, so the RSJ is a cold...

I have the spec of my padstones from my SE - but he has gone AWOL and I am unable to clarify with him what exactly he means. This is a single RSJ, with top plate, that will be supporting an old, standard brick cavity wall (approx. 300mm wide). The structural calcs refer to "Padstone 1 & 2" -...

Guys, Any advice.. SE specified bolts and spacers necessary. Builder has added bolts but not spacers. The work is up and he is saying spacers are not needed and is pushing back (basically refusing) on making changes now. The beams sit right next to each other - no space in between - is it...

Hi, I am taking a corner out of the kitchen on the ground floor which will be supported by a 'T' RSJ section. The largest RSJ (203 x 203 x52) has a span of 5m. One end will be on the original 9inch brick pier and the other will be on a new 300mm wall (inner leaf - 100mm). The builder has built...

Guys, I have a builder in doing some work for me. He put up an RSJ where there was previously a load bearing wall. Can you comment on the photos? I'm not 100% confident in what's been done. New RSJ spans 5 metres and also supports smaller pre-existing RSJ. Areas of concern, - Pad stone 80mm...

Hello, sorry if this isn’t the right place, it’s my first time posting. I have a couple of question, both things I’m a little uneasy about. I have a builder working on a loft conversion and it has a large steal going across the ridge, my concern is it looks like that steal is only supported on...

Hi, I am a new member here, in the process of buying a 3 bed 2 storey 1970's house and have noticed cracking in the masonry where the rear (single storey) extension meets the building. The cracks are stepped and go through both the bricks and the mortar. The extension itself is around 15 years...

Hi everyone, sorry for the second post in one day. I am currently looking to install an RSJ and steel column in my house in place of a load bearing wall. My question is in regards to how structural engineers normally model the connections. See diagram below: Screenshot 2021-03-25 At 14.42.00...

Hi all, I am looking to open up my downstairs with a few RSJs and columns, see images below: Existing 3D by Vennegoor posted 25 Mar 2021 at 2:18 PMProposed 3D by Vennegoor posted 25 Mar 2021 at 2:18 PMExisting Plan by Vennegoor posted 25 Mar 2021 at 2:18 PMProposed Plan by Vennegoor posted 25...

Hi, I'm planning to utilise my basement space (previously a garage) however I'm in need of creating some additional ceiling height - especially where currently positioned there is an RSJ. In summary, I want to remove it, and replace with wood in a similar arrangement to the rest of the house...

Hi all, im new to this site so bare with me.. im about to renovate a 1920/30’s semi-detached property, its a big job for me alone, it needs everything, from new concrete ground floors, new joists to 1st & 2nd floor, also partially new roof for a loft conversion.. ive already done the house next...

Hi, 3 years ago we had a 2 storey side / single storey rear extension added to our semi-detached house. This involved the removal of the "old" rear wall with RSJ installation. Since it was done we've had vertical cracks near the "join" in the rear extension, not deep not wide but definitely...

I have recently had RSJ's installed to prop up chimney stacks as the chimney breasts underneath were removed. The BC were informed and a structural engineer engaged. I provided the calculation and plans to the builder. I noticed that the fabricator had predrilled holes in the beams supplied ...

We live in a RedRow property built 2010 -Broadway Design- and we are removing the patio doors at the rear of the house. Does anyone have any experience of the homes to advise whether we have an RSJ? I was told by a chap who worked on our roof he was 100% certain a home built in 2010 would have...

We are in the early stages of deciding what we want to get from an extension on the rear of our 1950s semi. The existing house has a kitchen and dining room across the back of the house divided by a supporting wall. I have found it difficult to find much info on the topic although I’ve seen...

My wonderful builder left me with this mess after not quite finishing my extension. This is the bathroom above the kitchen where an RSJ ended up encroaching into the room at floor level. I want to tackle the puzzle of fireboarding it myself, but am not quite sure on what needs to be done to...
