Abstract (en)
A roof truss strengthening device (7) comprising first and second clamping members (8) each having at least two roughened timber-engaging areas (11) on confronting clamp faces, each said areas on one face being opposite a respective area on the other face to form opposed pairs and threaded means (9) linking said clamping members between each two adjacent opposed pairs of confronting roughened areas, whereby by drawing the clamping members towards one another on opposite sides of the timber lengths (1, 2, 3, 4) meeting at a junction point of a prefabricated roof truss (5), using said threaded means passing between timber lengths adjacent to the junction point, the device strengthens the bond between timber lengths meeting at said junction point.
