Trusses are typically composed of triangles because of the structural stability of that shape and design. However, other types of trusses are also known in the art. As aforementioned, there are different types of trusses with there being two basic types for which the first is a pitched truss otherwise known as a common truss which is characterised by a triangular shape. The second type of truss is known as a parallel chord truss or flat truss and is characterised by parallel top and bottom chords.
- Typically, most trusses are formed of a metallic material utilizing welding to interconnect the various frame members. However, while welding provides a good quality final product, it requires a considerable amount of skilled labour which increases the cost of the truss.
- It is an object of the present invention to provide a truss which utilizes mechanical interconnections and which is relatively inexpensive to fabricate.
- According to one embodiment of the present invention, there is provided a truss comprising, two parallel longitudinally extending upper frame members, two parallel longitudinally extending lower frame members, the longitudinally extending upper and lower frame members forming a rectangular configuration having an upper side, a lower side, and first and second lateral sides, each of the upper and lower frame members having a plurality of connection points located therealong, the connection points forming a plurality of sets thereof, each set comprising four connection points with one connection point located on each frame member, first transversely extending horizontal member extending between the two parallel longitudinally extending upper frame members, third and fourth transversely extending horizontal members extending between the two parallel longitudinally extending lower frame members, first and second diagonally extending members, the diagonally extending members extending between one of the connection points and a midpoint on another of the longitudinally extending members.
