<p>A prefabricated building unit is formed as an integrally moulded body of fibre-reinforced concrete. The body has a wall, a beam extending along the top or bottom of the wall, and a floor or roof extending from the beam perpendicularly to the wall at the bottom or top thereof respectively. The beam is reinforced by reinforcing bars extending there along and an elongated reinforcing member extending helically around the reinforcing bars.</p> |
