Flying shoring with neat sketches

Short answer

Flying (horizontal) shore supports two parallel walls with a gap of 3–9 m using horizontal shores, needles, wall plates, struts, straining pieces and folding wedges. No part touches the ground, keeping the area clear. A single shore covers up to 9 m; a double (compound) shore is used for wider gaps.

Describe flying shoring with neat sketches.

Flying (horizontal) shore: used when two parallel walls with a narrow gap (3-9 m) between them are to be supported, e.g. when the building between them is demolished. A horizontal shore is fixed between wall plates on the two walls, supported on needles, with inclined struts from lower needles up to straining pieces on the horizontal shore. No part touches the ground, hence "flying".

  wall                                      wall
  |  ||==N====== horizontal shore ======N==||  |
  |  ||     [sp]                  [sp]     ||  |

  |  ||  /                              \  ||  |
  |  ||N/                                \N||  |
  |  ||                                    ||  |
  || = wall plate, N = needle, [sp] = straining piece

A single flying shore is used for gaps up to about 9 m; a double (compound) flying shore is used for wider gaps. The system is cheaper than raking shores and keeps the ground clear for work.

Parts: wall plates, needles, horizontal shores, struts, cleats, straining pieces and folding wedges.
