Abstract: A floor frame comprised of floor joists and bearers formed from rolled strip steel, the floor joist including an end portion, said end portion being substantially orthogonal to a longitudinal axis of the floor joist and butting a bearer which lies substantially orthogonally to the floor joist, the floor joist and bearer being fixed together with fixing elements which pass through the end portion and bearer.

Abstract: A method of forming a tube involves the punching of tabs from overlapping longitudinal seam and folding the tabs to mechanically fix the opposed lateral edges of the sheet material forming the tube.

Abstract: A tie-down connecting elements (30) for tying down a truss relative to a wall frame is fixed between the webs (12) of the upper and lower Z-shaped chords (10) and includes a tongue portion (34) which extends downwardly through a slot (50) formed in the lower flange (16) of the lower chord (10) of the truss.

Abstract: Roof trusses (2, 4, 6, 8) are fixed together by a snap-fit connection system. The roof truss assembly includes a first truss (2) including an aperture having an enlarged portion (26) and a slot portion (28) communicating with the enlarged portion and extending away from the enlarged portion in a slot direction and a second truss (4, 6) including a pin (22) having a neck portion (30) and a head portion (32). The enlarged portion (26) of the aperture is adapted to receive the head portion (32) of the pin (22) during converging relative movement of the trusses. Subsequent relative movement of the second truss (4, 6) in the slot direction causes the neck portion (30) of the pin (22) to be received in the slot portion (28) of the aperture whereat diverging relative movement of the trusses is prevented. The truss assembly further includes a locking member (24) for preventing reverse relative movement of the second truss (4, 6) in a direction opposite to the slot direction.

Abstract: The present invention relates to a structural member (10) for the use as a chord (41, 42) for forming a roof truss (40) for a building.
