Top-chord bearing joist

1. A joist comprising:

an outer top chord and a bottom chord; and

an end configuration with at least one end of the joist and including a board connecting the outer top chord and the bottom chord, an inner top chord underlying the outer top chord and defining therewith a double top chord section, a post extending between the bottom chord and the double top chord section and juxtaposed outwardly to the board and toward the end of the joist, the double top chord section extending outwardly past the post and the bottom chord, the inner top chord having an elongated inner top chord groove defined therein with at least a section of the board being inserted in the elongated inner top chord groove.

2. A joist as claimed in claim 1 , wherein the board extends through the elongated inner top chord groove and has an edge at least partially inserted in an elongated groove defined in the outer top chord.

3. A joist as claimed in claim 1 , wherein the board has an edge at least partially located in the elongated inner top chord groove.

4. A joist as claimed in claim 1 , wherein at least one of the outer top chord, the inner top chord, the bottom chord, and the post is a wooden member and wherein the joist further comprises a first set of metal plates in alignment on opposed sides of the joist to connect the double top chord section and an upper end of the post.

5. A joist as claimed in claim 1 , wherein the post comprises an elongated post groove in which an outer edge of the board is at least partially inserted.

6. A joist as claimed in claim 1 , wherein the double top chord section defines a joist extension extending outwardly past the bottom chord for supporting the joist in a top chord bearing relationship.

7. A joist as claimed in claim 1 , wherein the post is substantially perpendicular to the double top chord section and the bottom chord.

8. A joist as claimed in claim 1 , wherein the inner and the outer top chords are in direct juxtaposition and extend substantially parallel to one another.

9. A joist as claimed in claim 1 , wherein the inner top chord extends inwardly past the post and an end of the post abuts a lower face of the inner top chord.

10. A joist as claimed in claim 1 , further comprising a central section including at least one of a board and web members connecting the outer top and bottom chords and metal plates securing an inner end of the inner top chord to the outer top chord.

11. A joist comprising:

a bottom chord;

a double top chord extending outwardly past the bottom chord at an end section of the joist and including an outer top chord member extending along the joist and an inner top chord having an elongated groove defined therein;

a board connecting the double top chord and the bottom chord and having a section inserted in the elongated groove defined in the inner top chord; and

a post extending in the end section of the joist between the double top chord and the bottom chord, the post being juxtaposed outwardly to the board and toward the end of the joist, and, the double top chord extending outwardly past the post.

12. A joist as claimed in claim 11 , wherein the board extends through the elongated groove defined in the inner top chord and has an edge at least partially inserted in an elongated groove defined in the outer top chord.

13. A joist as claimed in claim 11 , wherein the board has an edge at least partially located in the elongated groove defined in the inner top chord.

14. A joist as claimed in claim 11 , wherein at least one of the outer top chord, the inner top chord, the bottom chord, and the post is a wooden member and the joist further comprises a first set of metal plates in alignment on opposed sides of the joist to connect the double top chord and an upper end of the post.

15. A joist as claimed in claim 11 , wherein the post comprises an elongated post groove in which an outer edge of the board is at least partially inserted.

16. A joist as claimed in claim 11 , wherein the double top chord defines a joist extension extending outwardly past the bottom chord for supporting the joist in a top chord bearing relationship.

17. A joist as claimed in claim 11 , wherein the inner and the outer top chords are in direct juxtaposition and extend substantially parallel to one another.

18. A joist as claimed in claim 11 , wherein the post is substantially perpendicular to the double top chord and the bottom chord, the inner top chord extends inwardly past the post and an end of the post abuts a lower face of the inner top chord.

19. A joist as claimed in claim 11 , further comprising a central section including at least one of a board and web members connecting the outer top and the bottom chords and metal plates securing an inner end of the inner top chord to the outer top chord.

20. A joist comprising:

a bottom chord;

an outer top chord extending past the bottom chord at an end section of the joist;

a board connecting the outer top and bottom chords and extending at least in the end section of the joist;

an inner top chord underlying the outer top chord, extending past the bottom chord for supporting the joist in a top-chord bearing configuration, and having an elongated groove defined therein in which the board is inserted; and

a post extending between the inner top chord and the bottom chord and being juxtaposed outwardly to the board and toward the end of the joist.

21. A joist as claimed in claim 20 , wherein the board extends through the elongated groove defined in the inner top chord and has an edge at least partially inserted in an elongated groove defined in the outer top chord.

22. A joist as claimed in claim 20 , wherein the board has an edge at least partially located in the elongated groove defined in the inner top chord.

23. A joist as claimed in claim 20 , wherein at least one of the outer top chord, the inner top chord, the bottom chord, and the post is a wooden member and the joist comprises a first set of metal plates in alignment on opposed sides of the joist to connect the inner and outer top chords and an upper end of the post.

24. A joist as claimed in claim 20 , wherein the post comprises an elongated post groove in which an outer edge of the board is at least partially inserted.

25. A joist as claimed in claim 20 , wherein the inner and the outer top chords define a joist extension extending outwardly past the bottom chord for supporting the joist in the top-chord bearing relationship.

26. A joist as claimed in claim 20 , wherein the post is substantially perpendicular to the inner and the outer top chords and the bottom chord.

27. A joist as claimed in claim 20 , wherein the inner and the outer top chords are in direct juxtaposition and extend substantially parallel to one another.

28. A joist as claimed in claim 20 , wherein the inner top chord extends inwardly past the post and an end of the post abuts a lower face of the inner top chord.
