Needle

1.) A short strong piece of timber which goes through a hole in a wall and which, via props or shores on either side of the wall supports the wall for further work.
2.) A short timber or steel member which passes through a hole in the wall to support a scaffold etc.

Above is a sketch of a typical application for this beam. This is a sectional view through part of a wall that is supported by a beam, either steel or timber on dead shores or props. This would be done say if underpinning work was to be done on the foundations. This system takes the load off the wall and spreads it to either side

Note! steel is by far the material of choice for this application because of it's strength, but the steel needle-beam should always have a timber packer between it and the masonry. This provides a cushioning effect and to give some "grip".

All for ourselves, and nothing for other people, seems, in every age of the world, to have been the vile maxim of the masters of mankind." Adam Smith 1723-1790
