ashthekid Posted March 24, 2021 Share Posted March 24, 2021 (edited) Looking at getting a horizontal steel beam fixed to the front of a steel frame so not directly connected in line but one that sits of the front. You'll see what I mean in the image below. I'd like to know what kind of fixing or bracket you think is best for fixing this securely and safely?

markc Posted March 24, 2021 Share Posted March 24, 2021 Is the beam just to span an opening with load above? and sitting on side supports like a lintel? or will the beam be transferring load to the upright column/cranked beam? Link to comment Share on other sites More sharing options...
ashthekid Posted March 24, 2021 Author Share Posted March 24, 2021 Yes, to span an opening. The plan is to have it sat on a brick and flint wall either side but the support to be from the bracket to the steel post. The only reason we've added it is to support the wall of glazing with bifolds below and fixed glazed windows above. It's also to support the weight of that fixed glazing above but also stop any wind deflection. It's just how we fix it to the steel posts either side to secure it properly?

PeterW Posted March 24, 2021 Share Posted March 24, 2021 How are you stopping the cold bridging ..? Link to comment Share on other sites More sharing options...

In that case it isn't a simple restraint fixing. You need to know the total loads imposed on the beam, Is the vertical leg of the cranked beam designed for the cantilever loads of the new beam and all loads? Is the cranked beam top fixing designed for the additional cantilevered load? Personally i would make the two side masonry columns structural and support the loads, and only fix for restraint.

ashthekid Posted March 25, 2021 Author Share Posted March 25, 2021 The two side masonry columns are made up of the front layer bricks and flint and then a layer of concrete blocks so could potentially be used to take the support of the beam and then fixed to the steel post. I believe the plan is for the beam's load to be shared by the brick column as well as the steel posts. There wasn't going to be this beam at all, it's a last minute addition for stability at my request. The cold bridging is being stopped by insulating the beam and then face plates by the aluminium framing. Link to comment Share on other sites More sharing options...
markc Posted March 25, 2021 Share Posted March 25, 2021 @ashthekid In that case i would go for a site weld assuming the cranked beam is already in place, if not the steel supplier will sort the connection detail. Link to comment Share on other sites More sharing options...
