Abstract: A self-adjusting heel joint connector for securing roof structural members, without the need for a conventional birdsmouth cut or toe-nailing. The connector is slideably insertable between a bottom surface of a preset rafter and the top of a supporting wall plate at a heel joint and is capable of self-adjusting to the precise preset rafter pitch. The connector includes a framing member securable to the top of the supporting wall plate, and a support member rotatably coupled to the framing member and freely rotatable about an axis of rotation perpendicular to a longitudinal axis of the framing member. The framing member is securable to the angled rafter and an adjacent joist/tie member, as well as to the supporting wall plate, at the heel joint, and the rafter is supported by a substantially flat mating surface of the support member which extends in a direction perpendicular to a vertical leg of the framing member.

Abstract: A fastener guide for accurate spacing and aligning of fastening means in light wood frame construction, comprising a vertical leg comprising a generally flat rigid material and including a plurality of through-holes spaced according to a calculated matrix for driving fasteners therethrough to secure a first structural member to a second structural member, and a flange attached to or integral with the vertical leg and positioned approximately at a right angle thereto. The fastener guide is placed against a face of the first structural member such that the vertical leg plurality of through-holes are positioned to allow for transfer of thrust, tension and shear forces to the second structural member oriented adjacent thereto at a building frame joint. Fasteners are driven through the plurality of through-holes into the second structural member to secure the first structural member to the second structural member.

The connector is slideably insertable between the bottom of a preset rafter and the top of a supporting wall plate at a heel joint and is capable of self-adjusting to a precise preset rafter pitch. The connector includes a support member securable to the top of the supporting wall plate, and a framing member freely rotatable with respect to the support member about a swivel joint. The framing member is securable to the angled rafter and an adjacent joist/tie member, and includes a pair of legs positioned at approximately a right angle in which the rafter sits. The framing member includes through-holes for securing the connector to an angled rafter and an adjacent joist/tie member, and may be utilized as a guide for proper fastener placement by a craftsman in the field.

Abstract: A multi-heel connector for securing a rafter, a ceiling joist and blocking, and supporting building roof structural members in a single bracket connection to withstand enhanced load forces such as hurricane forces. The multi-heel connector combines a loop portion for securing a joist, a rafter contact surface adjacent the loop portion, having a slope which provides for a selected, predetermined roof pitch, mounting tabs for securing the multi-heel connector to a top wall plate, tabs to fasten blocking and a tie down for securing the multi-heel connector to exterior wall stud. The multi-heel connector is adaptable for accommodating a riser key to adjust the rafter contact surface pitch, and a joist spacer to accommodate a joist having a cross-section smaller than the multi-heel connector loop portion cross-section.

Abstract: This specification discloses a method and construction for joining the ends of concrete reinforcing bars which permits the development of both tension and compression in the bars. A joining member compressively engages adaptor members integrally joined to the ends of the bars and reacts any forces tending to separate the bars, and further permits transmittal of compressive forces therebetween.

Abstract: This specification relates to apparatus and method for improving construction joints in reinforced concrete structures. A coupling member extends a short distance beyond the joint between two pours and has edges which mechanically couple to joining or adaptor members on the ends of reinforcing bars.
