Abstract
A lean-to construction is provided in which a horizontal beam is supported between a supporting structure and a vertical beam spaced from the supporting structure. The vertical and horizontal beams have interengaged end portions and a mortis and tenon joint is provided with a tongue having a configuration to vector the forces resulting from the weight of the horizontal beam into vertical and horizontal forces which urge the vertical beam to tilt towards the horizontal beam and supporting structure, thereby to make the structure more reliable.
