A wooden truss includes an elongated lower chord, first and second upper chords, and web members extending therebetween. Alternatively, the wooden truss includes two elongated chords and web members extending therebetween. A member identifier is printed on a broad face of at least one of such chords to identify such chord before assembly of the wooden truss. An assembled truss identifier is printed on an outward-facing edge of such chord to identify an assembled wooden truss incorporating such chord, wherein the assembled truss identifier is visible to an observer viewing a stack of such wooden trusses. The assembled truss identifier is printed a predetermined distance from a first end of such chord wherein such assembled truss identifiers are in alignment when a series of such wooden trusses are stacked adjacent to each other.

Provided is a composite deck plate capable of forming an attractive ceiling surface by incorporating an appealing design of a wood-based plate (natural material) into the ceiling surface.

A composite deck plate 10A includes a reinforced deck plate 15 and a wood-based plate 16 having a predetermined area and disposed under the reinforced deck plate 15. The reinforced deck plate 15 includes: a metal base 17 having a predetermined area and having a first end edge portion 20 and a second end edge portion 21 that face each other while being spaced apart from each other in a length direction and extend in a width direction, and a central portion 22 positioned between the first end edge portion 20 and the second end edge portion 21; and a reinforcing bar truss unit 19 (reinforcing structure) disposed and fixed on and to an upper surface 18 of the metal base 17 and extends in the length direction between the first end edge portion 20 and the second end edge portion 21 of the metal base 17. The wood-based plate is fixed to a lower surface 25 of the metal base 17 by a plurality of staples 42 arranged at equal intervals in the length direction.

Automated systems and methods of manufacturing truss elements for use in modular construction units can include stations, or steps, for forming angled webs, upright webs, and truss chords for use in the truss elements, transferring such angled webs, upright webs, and truss chords onto an assembly jig in a configuration corresponding to the truss element being manufactured, rigidly interconnecting, via nail plates, the angled webs, the upright webs, and the truss chords to form a finished truss element, and unloading the finished truss element from the assembly jig.
