Abstract

An elongated strap member that is coiled in a box and is bent lengthwise as it is drawn out of the box, providing an economical, light, compact means of connecting multiple structural members without sagging or other disadvantageous deformations between the structural members. The structural members are bridged by strap member. The end of the strap member is bent over.

Claims

1. A method of making a bent split strap (2), comprising:

(a) providing a generally flat, coiled, elongated strap (2) having a leading end (3) and a trailing end (4), a first elongated side boundary (5) and a second elongated side boundary (6) generally parallel to said first elongated side boundary (5), a body (7) bounded by said first and second elongated side boundaries (5, 6) that define a width (8), and an elongated slit cut (9) generally parallel to said first and second elongated side boundaries (5, 6), said slit cut (9) dividing said body (7) between said first and second elongated side boundaries (5, 6), creating a first body side (10) and a second body side (11), said slit cut (9) being intermittently interrupted by unslit portions (12) that connect said first and second body sides (10, 11);

(b) providing an aperture (13) having a first end (14) and a second end (15) that define a width (16), said width (16) of said aperture (13) being less than said width (8) of said elongated strap (2); and

(c) drawing said elongated strap (2) through said aperture (13) so that said first and second ends (14, 15) of said aperture (13) constrict said elongated strap (2) by bearing on said first and second elongated side boundaries (5, 6), thereby bending said elongated strap (2) along said slit cut (9) to create an elongated bend (17) in said elongated strap (2);

wherein;

i. said elongated strap (2) is provided in a box (18) that contains the majority of said elongated strap (2).

2. The method of claim 1, wherein:

(a) said aperture (13) is has a first straight leg (19) and a second straight leg (20), said first and second straight legs (19, 20) meeting at a first angular juncture (21); and

(b) said elongated strap (2) is drawn through said aperture (13) so that said slit cut (9) coincides with said first angular juncture (21), said first body side (10) coincides with said first straight leg (19), and said second body side (11) coincides with said second straight leg (20), thereby bending said elongated strap (2) along said slit cut (9) to create said elongated bend (17) in said elongated strap (19).

3. The method of claim 1, wherein:

(a) said first body side (10) and said second body side (11) are stamped with repeating patterns of dimples (22) that aid in positioning fasteners (23) by providing areas of higher friction than the undimpled portions of said first body side (10).

4. A method of making a bent split strap connection (1), comprising:

(a) providing a generally flat, coiled, elongated strap (2) having a leading end (3) and a trailing end (4), a first elongated side boundary (5) and a second elongated side boundary (6) generally parallel to said first elongated side boundary (5), a body (7) bounded by said first and second elongated side boundaries (5, 6) that define a width (8), and an elongated slit cut (9) generally parallel to said first and second elongated side boundaries (5, 6), said slit cut (9) dividing said body (7) between said first and second elongated side boundaries (5, 6), creating a first body side (10) and a second body side (11), said slit cut (9) being intermittently interrupted by unslit portions (12) that connect said first and second body sides (10, 11);

(b) providing an aperture (13) having a first end (14) and a second end (15) that define a width (16), said width (16) of said aperture (13) being less than said width (8) of said elongated strap (2);

(c) drawing said elongated strap (2) through said aperture (13) so that said first and second ends (14, 15) of said aperture (13) constrict said elongated strap (2) by bearing on said first and second elongated side boundaries (5, 6), thereby bending said elongated strap (2) along said slit cut (9) to create an elongated bend (17) in said elongated strap (2);

(d) cutting a length of said bent split strap (2);

(e) providing a plurality of parallel structural members (24), said structural members (24) each having an interface surface (25);

(f) fastening said body (7) of said length of said bent split strap (2) onto each of said interface surfaces (25) of said structural members (24).

5. The method of claim 4, wherein:

(a) said bent split strap (2) is fastened onto said interface surface (25) of said structural members (25) with a plurality of fasteners (23).

6. The method of claim 5, wherein:

(a) at least one of said fasteners (23) penetrates each of said structural members (24).

7. The method of claim 6, wherein:

(a) said structural members (24) are made of wood.

8. The method of claim 7, wherein:

(a) said fasteners (23) are nails (23).

9. The method of claim 6, wherein:

(a) said structural members (24) are made of metal.

10. The method of claim 9, wherein:

(a) said fasteners (23) are screws (23).

11. The method of claim 4, wherein:

(a) said structural members (24) are wall studs (24).

12. The method of claim 4, wherein:

(a) said structural members (24) are floor beams (24).

13. The method of claim 4, wherein:

(a) said structural members (24) are truss chords (24).

14. The method of claim 13, wherein:

(a) said truss chords (24) are the top chords (24) of roof trusses.

15. The method of claim 4, wherein:

(a) said bent split strap (2) is flattened where it is fastened to said structural members (24) and remains bent between said structural members (24) so that it does not sag.
