DETAILED DESCRIPTION OF THE INVENTION

[0052] The present invention is a building structural connection 1 between a first structural member 2 and a second structural member 3. Preferably, the first structural member 2 is a supporting member or anchoring member 2 and the second structural member 3 is a supported structural member 3. As shown in FIG. 1, the first structural member 2 is a floor member that is horizontally disposed 2 with an attached ledger and the second structural member 3 is a vertically-oriented channel-shaped wall post or stud 3 that is part of a wall.

[0053] The connection 1 between the first structural member 2 and the second structural member 3 is made with a first angled connector 4. The first angled connector 4 is preferably L-shaped, with a first plate 5 fastened to the first building structural member 2 and a second plate 6 fastened to the second building structural member 3. Preferably, the first plate 5 and the second plate 6 are generally planar and joined at right angles to each other. The connector 4 allows for relative vertical movement between the first and second building structural members 2 and 3. The connector 4 is preferably made from cold formed sheet steel formed on automated manufacturing machinery as much as possible.

[0054] As shown in FIG. 2, the first plate 5 has first and second fastener openings 7 and 8. Fastener openings 8 are larger than fastener openings 7 to accommodate larger fasteners. The angled connector 4 shown in FIG. 2 is attached to the second structural member by welds 9.

[0055] The first plate 5 has a first inner edge 11, a first outer edge 12, a first side edge 13 and a second side edge 14.

[0056] As shown in FIG. 2, the second plate 6 has a plurality of fastener openings 10 and 15 formed as elongated slots. The second plate is also provided with a first inner edge 16, a first side edge 17 and a second side edge 18. The first inner edge 11 of the first plate 5 is joined to the first inner edge 16 of the second plate 6 to form an inner angular juncture 19. Preferably the inner angular juncture 19 is 90 degrees. One of the slotted openings 10 lies closer to the 19 juncture than the other slotted openings 15. The slotted openings are preferably disposed parallel to the angular juncture 19 between the first plate 5 and the second plate 6. Each elongated slot 10 and 15 in the second plate 6 is a site of a fastening to the second structural member 3.

[0057] As shown in FIG. 2, the connector 4 includes a plurality of gusset darts 26 having a substantially triangular shape when viewed from a lateral side thereof, the substantially triangular shaped gusset darts 26 are disposed in the inner angular juncture 19 between the plates 5 and 6. The gusset darts 26 preferably have a substantially u-shaped cross-section. The gusset darts 26 reinforce the inner angular juncture 19.

[0058] Preferably, a first plurality of fasteners 27 attaches the first plate 5 to the first building structural member 2. As shown in FIG. 2 the fasteners 27 can be welds 9, but anchors and screws received in the fastener openings 7 and 8 are also preferred. A plurality of fasteners 28 preferably attaches the second plate 6 to the second building structural member 3. Preferably, the fasteners 28 that attach the second plate to the second structural member are screws 28 of similar dimensions. The preferred fasteners 27 for attaching the connector 4 to first structural member 2 made from steel are hex-head fasteners, automated power-actuated gun-driven fasteners or, alternatively, welds 9. The preferred fasteners 27 for attaching the angled connector 4 to first structural members 2 made from concrete are concrete screws. The preferred fasteners 28 for attaching the connector 4 through slots 10 and 15 are shouldered, or stepped-shank, self-drilling screws 28.

[0059] As shown in FIG. 1, the second plurality of fastener openings 10 and 15 is preferably formed as a plurality of elongated slots 10 and 15 in the second plate 6 as movement between the structural member 3 and the connector 4 is desired. When the fastener 28 is drilled into or connected to the stud or second structural member 3, the fastener is anchored in the stud 3. When the stud 3 moves relative to the first structural member 2 the fastener 28 moves in the elongated slot 15. Preferably, the first building structural member 2 is fastened to the angled connector 4 so that the first building structural member 2 cannot move relative to the first plate 5 of the first connector 4. The second building structural member 3 is preferably fastened to the first connector 4 so that the second building structural member 3 can move relative to the second plate 6 of the first connector 4. The plurality of elongated slot openings 10 and 15 that extend across the second plate 6 extend generally parallel to the inner angular juncture 19 between the first plate 5 and the second plate 6.

[0060] Preferably, the fasteners of the second plurality of fasteners 28 are shouldered, or stepped-shank screws 28. Shouldered screws 28 have a head 29, an unthreaded shank portion 30 immediately below the head 29, a threaded shank portion 31 below the unthreaded shank portion 30, and a tip 32. The tip 32 is preferably a self-drilling tip. The unthreaded shank portion 30 allows the second building structural member 3 and the fasteners 28 attached to it to move relative to the second plate 6 without interference between the second plurality of fastener 28 and the second plate 6 of the first connector 4, because the unthreaded shank portion 30 stops driving of the fastener 28 before the head 29 of the fastener reaches the second plate 6. The tip 32 is designed to drill itself into the web 33 of the stud 3. The web 33 of the stud is preferably a substantially planar member.

[0061] Each elongated slot 10 and 15 in said second plate 6 is a site of a fastening to the second structural member 3, and each elongated slot 10 and 15 preferably receives at least one fastener 28 having an elongated shank and a head 29, wherein the elongated shank of each fastener 28 is received in the second structural member 3, and each at least one fastener 28 can move along the elongated slot 15 in the second plate 6 when the second structural member 3 moves with respect to the second plate 6. As shown in FIG. 1, the reinforcing member or bracket 34 reinforces the connection between the angled connector 4 and the second structural member 3 near the fastening in the elongated slot 10 closest to the angular juncture 19.

[0062] As shown in FIG. 1, the reinforcing member 34 is a single bracket attached to the second structural member 3 and overlies the angle connector 4 close to the elongated slot 10 closest to the angular juncture 19. As shown in FIGS. 1 and 2, the reinforcing member 34 spans a distance greater than that of the angled connector 4 along the length of the second structural member 3 and is anchored to the second structural member 3 away from the first and side edges 13 and 14 of the second plate 6 of the angled connector 4. The reinforcing member is connected to the second structural manner 3 in a manner that allows for the same amount of movement between the second structural member 3 and the angled connector 4 as would occur if the reinforcing bracket 34 was not used.

[0063] As shown in FIG. 12, the reinforcing member 34 can be formed with an extending flange 35 so that the reinforcing member 34 can interface and be attached to a side flange 38 of the second structural member 3. The second structural member 3 preferably has an attachment face 36 and an opposite face 37, and the second plate 6 has an attachment side 40 and an open side 41 facing in the opposite direction. The attachment side 40 of the second plate 6 faces the second building structural member 3. The side flange 38 is set a different angle to the attachment face 36 of the second structural member 3. The angular connector 4 is preferably disposed on the attachment face 36 as shown in FIG. 12. Preferably, as shown in FIG. 12 the overlying portions 39 of the reinforcing member 34 can press against the open side 41 of the second plate 6 if the angled connector 4 tries to pull away from the second stud 3. Preferably, the overlying portions 39 of the reinforcing member 34 are located in close proximity to the open side 41 of the second plate 4 without being in contact with the second plate 4 so as to not interfere with any movement of the second structural member 3 along its longitudinal axis 45. The reinforcing member 34 resists the angled connector 4 being moved from the second structural member 3 orthogonally to the longitudinal axis 45 of the second structural member 3, as when the second plate 6 may try to separate from the second structural member 3 under certain load conditions.

[0064] As best shown in FIGS. 6, 17 and 27, any portions of the reinforcing member 34 that may interfere with the movement of the second structural member 3 along the longitudinal axis of the second structural member 3 with respect to the angled connector 4 are spaced a selected distance away from the side edges 13, 14, 16 and 17 of the first and second side plates 5 and 6 of angled connector 4. In this manner the second structural member 3 can move with respect to the second plate 6 along the longitudinal axis of the second structural member 6 and the reinforcing member 34 does not interfere.

[0065] As shown in FIG. 1, the reinforcing member 34 can be formed with a pair of attachment flanges 44 that interface with the attachment face 36 of the second structural member 3 and which are joined by a central bridge 48 that has portions that overlie the angled connector 4. The reinforcing member 34 shown in FIG. 1 is connected to the second structural member 4 by fasteners 46 at the attachment flanges 44. As shown in FIGS. 12-15 the reinforcing member 34 can be formed with one or more extending flanges 35 that interface with and attach to the side flange 38 of the second structural member 3. As best shown in FIG. 18, the central bridge 48 can be formed with a strengthening flange 47 along the upper portion of the central bridge 34

[0066] As shown in FIGS. 23 and 33, the reinforcing member 34 can have a stepped central bridge 45 with a series of different elevations to clear the various portions of the angled connector 4 and fasteners 28 which it overlies.

[0067] As shown in FIG. 2 the first plate 5 has an attachment side 42 and an open side 43 facing in the opposite direction. The attachment side 42 of the first plate 5 faces the first building structural member 2.
