My latest struggle is trying to design and spec a flying shore to span 19m between two buildings to replace its current raking shores.. 19 metres! Anyone who spends 5 minutes reading anything worth reading in the temporary structural support library knows that a timber flying shore only stretches to 12 metres, and I’m still searching for proof that 19 metres can be achieved in steel.
Flying shores are a temporary (or permanent) frames that support walls and structures that cannot stand alone. In the photo, the flying shore fills a gap created when a building had been removed from within a row or terrace. The load from the surrounding buildings that the removed one had held is now taken by the flying shores – without it, the weight of the buildings would cause them to collapse inwards, into the void left. The benefit of a flying shore, as opposed to a raking shore, is that it leaves a clear space at ground level. This space could be used to construct another building in the space (in the case of a temporary shore), or become a permanent space such as a car park.
Despite my frustration at the engineering of them, it’s always nice to see an example of the technology you have to design. This flying shore is on Angel Row, in Nottingham (next to the city library).
