Abstract

Trench lining key pieces (I) link sheeting (P) to posts etc, and comprise twin parallel rectangular plates (II, Ie joined by a third rectangular plate (III) perpendicular to the first plates. The third plate width is about half the length of the first plates and connects symmetrically to them. The key fits into a T shaped groove in the vertical board (M) and lodges symmetrically at the junction of four horizontal sheeting planks (P), i.e. at four abutting corners, locking planks to prevent lateral and vertical movement but permitting longitudinal sliding; the connection also permitting vertical sliding of boards.
