RE: shoring / lintel information required re extending opening
i was thinking of shoring internally the room with a wall plate a floor plate and 4x2" struts every 3 ft about 1 ft from the wall face
but it is a cavity wall so i was worried about supporting the external wall
eventually i will be leaving a horizontal bearer timber in place to allow me to position temporary spider beams over a proposed glass roofed conservatory so allowing safe boarded access to aircon equipment etc
so this bolted beam may assist in that
i can remove the inner beam after lintle in place and secure the bolts within the recess of the wall and decorate over.
suggestions?

That having been said, the most common way I see contractors shoring for lintel installation is with wood or steel needle beams (thru the wall) perhaps every 4 feet on center with posts on the inside and outside the wall.

My first post, trust it reaches you.
RE: shoring / lintel information required re extending opening
i was under the impression that taking the weight of the ceiling / floor in the room with the existing opening would allow work to be carried out but i now understand that the weight is actually the wall and not necessarily the floor area.
i assume therefore that the openings for the needles must be quite large
i was hoping to utilise 50mm steel scaffold poles as pinns every 2 feet perhaps
thereby limiting structural damage to surrounding

have spoken to partner in crime and he has suggested a combination of ideas
ie internally a scaffold board floor and ceiling plate with acrow jacks supporting and then load sharing timber beam across floor of room above. needles to rest on load sharing beams.
externaly beams supported by acrow jacks.
overall lintel length will be 3.6 m
