## Question

Describe 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.

## Answer

**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 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.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Where is a flying shore used?
   A. On a single leaning wall with a slope
   B. Under a wall being removed
   C. Between two parallel walls with a narrow gap of about 3-9 m
   D. Around a foundation pit
   Answer: C. Flying shores brace two parallel walls against each other, for example after the building between them is demolished. (Key point: Flying shore use)

2. Why is it called flying shore?
   A. It moves with wind
   B. It is erected by crane
   C. It is made of light timber
   D. No part touches the ground
   Answer: D. Horizontal members span between walls so the ground stays clear. (Key point: Why flying)

3. Which is a part of a flying shore?
   A. Wall plates, needles, horizontal shores, struts and cleats
   B. Slate packing
   C. Sole plate on ground
   D. Putlogs and ledgers
   Answer: A. The system uses wall plates, needles, horizontal shores, struts, cleats and straining pieces. (Key point: Parts)
