Tension bracket

1. An installation comprising:

a bracket comprising a mounting base comprising two substantially coplanar base sections having adjacent complementary edges and each defining a plurality of fastener openings and comprising a guide having parallel walls with an abutment end disposed above and generally perpendicular to said base sections and comprising a pair of laterally spaced reinforcement ribs projecting generally perpendicularly from said base sections;

a first member;

a second member;

a plurality of fasteners each extending through an opening to secure said base sections to said first member;

an elongated fastener having a head portion and a threaded tip portion and received in said guide wherein said thread tip portion is driven into said second member and said head portion exerts a force against said abutment end to connect said first member to said second member under tension.

2. The installation of claim 1 and further comprising a retainer washer engaged by said head portion wherein said retainer washer has a pair of wings which engage rear portions of said walls of said guide.

3. The installation of claim 2 wherein said fastener has an unthreaded portion and at least one mark is disposed on said unthreaded portion.

4. The installation of claim 1 wherein said sections cooperatively define an opening larger than and generally complementary in shape to a profile of the head portion of the fastener.

5. An installation comprising:

a bracket comprising a mounting base comprising two substantially coplanar base sections having adjacent complementary edges and each defining a plurality of fastener openings and comprising an elevated guide having a quasi-U-shaped portion and a pair of parallel walls each having an abutment end disposed above and generally perpendicular to said sections, the adjacent complimentary edges defining an opening therebetween to accommodate a portion of a fastener;

a joist;

a structural member;

a plurality of fasteners each extending through a fastener opening to secure said base sections to said joist;

an elongated fastener having a head portion and a threaded tip portion and received in said guide wherein said thread tip portion is driven into said member so that said head portion engages said abutment end to connect said joist to said member under tension.

6. The installation of claim 5 wherein each abutment end has a concave shape portion with a radius of curvature and further comprising a washer received by said fastener and having a shape complementary to said concave shape.

7. The installation of claim 1 , wherein the first member and second member are both made of wood.

8. The installation of claim 1 , wherein each wall of the guide defines a rear edge that abuts the head of the elongated fastener.

9. The installation of claim 8 , wherein the guide defines a forward wall opposite the rear edges, the forward wall defining an edge that is angled obliquely relative to the substantially coplanar base sections.

10. The installation of claim 1 , wherein the adjacent complimentary edges define an opening portion therebetween shaped and sized to accommodate a portion of a fastener.

11. The installation of claim 1 , wherein the opening portion is shaped substantially like a profile of a fastener having a head portion and a shank portion.

12. The installation of claim 1 , wherein the bracket extends from a proximal end to a distal end and the head of the elongated fastener is proximal to the threaded tip in the installation.

13. The installation of claim 12 , wherein the guide is positioned closer to the distal end than the proximal end of the bracket.

14. The installation of claim 1 , wherein the guide has a substantially U-shaped profile.

15. The installation of claim 1 , wherein the bracket is formed from a single integral sheet of metal material.

16. The installation of claim 1 , wherein the adjacent complimentary edges of the coplanar base sections each has at least a portion that is substantially linear.

17. The installation of claim 1 , wherein each of the substantially coplanar base sections has a lateral width, and the lateral width of one base section is substantially equal to the lateral width of the other base section.

18. The installation of claim 1 , wherein each of the substantially coplanar base sections extends longitudinally from a proximal end to a distal end and length between the proximal end and distal end is between 3.0 and 8.0 inches.

19. The installation of claim 1 , wherein each of the substantially coplanar base sections extends longitudinally a length L and the elevated guide extends from the base sections a height H, and the ratio of L to H is within the range of 2.5:1 to 5.0:1.

20. The installation of claim 1 , wherein the guide extends between 1.0 and 2.0 inches from the substantially coplanar base sections.

21. The installation of claim 5 , wherein said parallel walls have a forward edge which is inclined at an acute angle to said section surfaces.

22. The installation of claim 21 , wherein the elongated fastener is oriented with the head abutting a rear edge of the parallel side walls that is opposite the forward edges and the threaded tip portion extending past the forward edges.

23. The installation of claim 5 , wherein said opening to accommodate a portion of a fastener has the general shape of an enlarged profile of a portion of a fastener shank, a fastener head and a washer flange.

24. The installation of claim 5 , wherein one or more of the joist and the structural member is made from wood.

25. The installation of claim 5 , wherein each of the substantially coplanar base sections extends longitudinally from a proximal end to a distal end and length between the proximal end and distal end is between 5.0 and 6.0 inches.

26. The installation of claim 5 , wherein each of the substantially coplanar base sections extends longitudinally a length L and the elevated guide extends from the base sections a height H, and the ratio of L to H is within the range of 2.5:1 to 5.0:1.
