I am replacing my conservatory roof with a pitched tiled roof. I am replacing some of the windows but want to re-use the patio doors so am building a cavity wall in the two front corners to support the front & side lintels. Building control are ok with this except they want me to build a vertical steel support in the wall as it is only 500mm wide. He said I can put it either in the cavity which is 2” or in the inner wall. What should I use for this? And how should it be fixed to the horizontal lintel. My local suppliers cannot help me. I have some galvanized scaffold poles. Would these be sufficient if I had a base plate made for them. The extension is 2.14 m out & 4.2m wide.
is it to act as a wind post? in which case what are you fixing it to at the top?
is it to support the load from the lintel? the brcik will be able to do this?
is it to stop flexural cracking of the side wall?
get and SE to sort out either a post or a calc to prove the brickwork.
i think if the brick return is 625mm long you wont need the steel post.
