Abstract
A connection between a first, supporting structural member, such as a post or header, and a second, supported structural member such as a joist or rafter is provided, wherein the connection is made with a connector and fasteners, the use of which can be substantially hidden from view. The connector is designed to be inserted in a slotted opening in the second, structural member and to attach to a surface of the first, supporting structural member.
Claims19
A connection between a first structural member and a second structural member made with a connector and one or more first fasteners and one or more second fasteners, the connection comprising:
- a. the first structural member having an attachment surface;
- b. the second structural member having an abutment surface, the second structural member having a slotted opening in the abutment surface;
- c. the connector having a generally planar attachment web inserted in the slotted opening of the second structural member, the attachment web being defined by an outer edge and an oppositely disposed rear edge, an upper bracketing edge and an oppositely disposed lower bracketing edge, the connector having one or more generally planar fastening flanges connected to the rear edge of the attachment web, the one or more fastening flanges being disposed generally parallel to the attachment surface of the first structural member and at an angle to the attachment web, the one or more fastening flanges being connected to the rear edge of the attachment web by fastening flange bends that are substantially aligned with or adjacent to the rear edge of the attachment web, the one or more fastening flanges being attached to the first structural member by the one or more first fasteners, the attachment web being attached to the second structural member by the one or more second fasteners;
- wherein
- d. the lower bracketing edge has a rear termination point where the lower bracketing edge intersects with the rear edge of the attachment web, and a portion of the rear edge of the attachment web is generally linear, and the lower bracketing edge travels away from the rear termination point in a direction that is an acute angle to the linear portion of the rear edge, and the outer edge of the attachment web is disposed within the elongated slot in the second structural member;
- wherein
- e. the angle or slope of the bracketing edge changes at one or more intermediary points spaced along the bracketing edge, and the intermediary points occur along the lower bracketing edge between the rear termination point of the lower bracketing edge and an outer termination point of the lower bracketing edge where the lower bracketing edge meets the outer edge of the attachment web.

A connection between a first structural member and a second structural member made with a connector and one or more first fasteners and one or more second fasteners, the connection comprising:
- a. the first structural member having an attachment surface;
- b. the second structural member having an abutment surface, the second structural member having a slotted opening in the abutment surface;
- c. the connector having a generally planar attachment web inserted in the slotted opening of the second structural member, the attachment web being defined by an outer edge and an oppositely disposed rear edge, an upper bracketing edge and an oppositely disposed lower bracketing edge, the connector having one or more generally planar fastening flanges connected to the rear edge of the attachment web, the one or more fastening flanges being disposed generally parallel to the attachment surface of the first structural member and at an angle to the attachment web, the one or more fastening flanges being connected to the rear edge of the attachment web by fastening flange bends that are substantially aligned with or adjacent to the rear edge of the attachment web, the one or more fastening flanges being attached to the first structural member by the one or more first fasteners, the attachment web being attached to the second structural member by the one or more second fasteners;
- wherein
- d. the lower bracketing edge has a rear termination point where the lower bracketing edge intersects with the rear edge of the attachment web, and a portion of the rear edge of the attachment web is generally linear, and the lower bracketing edge travels away from the rear termination point in a direction that is an acute angle to the linear portion of the rear edge, and the outer edge of the attachment web is disposed within the elongated slot in the second structural member;
- wherein
- e. the attachment web is formed with 7 openings for receiving the second fasteners, the openings are arranged in three pairs of a openings, an uppermost pair of openings, a middle pair of openings and a lowermost pair of openings, and a lowermost single opening, within each pair of openings there is an upper opening and a lower opening offset from the upper opening, with the lower opening being located with its center approximately 1″ below the upper opening of the pair of openings and its center also being spaced 2″ horizontally from the upper opening of the pair of openings;
- f. the upper opening of the uppermost pair is located with its center 2.5″ below the upper bracketing edge of the attachment web, and the upper opening of each pair of openings is spaced approximately 2″ below the upper opening of the pair of openings above;
- the single lowermost opening is disposed approximately 2″ below the lower opening in the lowermost pair of openings.
