Abstract: The present disclosure relates to methods, apparatuses, and systems for manufacturing a building element. In one aspect, a molding system for forming a building element is provided. The molding system includes a mold having a base and a lid. The base includes a side wall; an adjustable internal side wall assembly comprising at least two internal side wall segments movable relative to the side wall and the other internal side wall segment and arranged in a piled stack; an end wall; and an adjustable internal end wall assembly comprising at least two internal end wall segments movable relative to the end wall and the other internal end wall segment and arranged in a piled stack. The side wall, the end wall, the floor, the lid, at least one internal end wall segment, and at least one internal side wall segment, co-operatively define a cuboid cavity for molding the building element.

Abstract: A batten for use in roofing applications is defined by an upside-down U-shaped channel with outwardly projecting horizontal flanges. In certain versions, the legs forming the sides of the channel are asymmetrical to allow vertical orientation of at least one of the legs when installed on an angled roof. This improves strength and load bearing of the installed member, and allows it to provide a fall barrier for roof installers. In certain versions, one of the flanges has a ribbed impact reduction zone. This zone deforms when a building anchor, such as a nail, passes through it to anchor the member to a roof. The deformation prevents anchors fired from conventional equipment from passing completely through the member and holds the anchors more securely in place.

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: A truss for a roof having an attic space or the like, the truss including: a substantially vertical web adapted to constitute a stud for supporting the attic wall; a substantially horizontal web adapted to constitute a support for the attic ceiling or ceiling battens, and a bottom chord adapted to constitute a bearer or joist for the attic floor.

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.
