Abstract: A metal structural tie strap for fastening two or more nailable wood members to one another; the strap being formed with nail openings which are equidistant from one another and fall within nail holding means adjacent the edges of the strap. The edges of the strap transverse to the longitudinal axis of the strap are non-linear, forming a pattern in which the leading edge is a reverse image of the trailing edge.
Abstract: A free gusset metal ledger hanger for attachment to metal ledgers wherein the hanger consists briefly of a top flange adapted for connection to the upper face of the outstanding ledger leg, a depending flange attached to the top flange and extending downwardly therefrom, first and second stirrup members attached to the depending flange and extending downwardly therefrom and adapted for holding a structural beam member, and a first gusset member operatively ridgedly connected to the top flange and having a top edge in registration with the lower face of the outstanding leg of the ledger and having a side face in close fitting relation to the outward face of the lower leg of the metal ledger.
Abstract: A positive nail-angling device for metal connectors for prevention of splitting due to beam "hanging" caused by side nailing and wood shrinkage and prevention of splitting of laminated members such as plywood, glued laminated timbers (glulam) and prefabricated wood joists (microlams). The device includes a slot-like opening formed in the face of a metal connector and a tab-like member formed from the displaced face material from the slot-like opening and bent along a bend line which constitutes one end of the slot-like opening. The slot-like opening and tab-like member in the connector confine the nail so that it can only penetrate the wood member at a pre-selected angle. In many applications, the tab-like member is bent at an angle of 45.degree. to the face of the metal connector.
Abstract: An infinite skewed and sloped sheet metal hanger for holding a supported structure to a supporting structure. The hanger consists of a supporting member which is connected to the supporting structure, a pin and a supported gusset-like member. Load shear is carried to the face support; not through the pivot connecting pin. This is accomplished by closely holding tab members with the supported gusset-like member.
Abstract: A metal connector for joining wood members which intersect at an angle less than 90 degrees formed with restricted slot nail openings so that the metal connector can be easily joined to the wood members by inserting the nail fastener into the nail opening at an angle other than a 90 degree angle. The opening has a width slightly larger than the diameter of the nail fastener and a length substantially greater than the diameter of the nail fastener. The nail is inserted into the opening at a selected angle so that the diagonally opposed outer edges of the sides of the opening tangentially register with the opposed sides of the fastener. When the nail is inserted there is little or no relative movement between the nail fastener and the connector.A method for forming a skewed connector formed with the restricted slotted nail fastener openings.
Abstract: A metal element for holding the wood wall frame members to the concrete building foundation to resist uplift and overturning forces due to earthquakes, hurricanes, tornadoes and other forces destructive to wood frame buildings.The holdown consists of a back member formed with openings for receiving fastening members for attachment to a vertical wood frame member, side members attached to the back member extending substantially the entire length of the holdown, a seat member including an opening for receipt of an attachment member for attachment to a concrete foundation, and a pair of foot members extending below the seat member for resting upon a sill member.
Abstract: A clip for attaching composite structural trusses to lateral bracing members consisting briefly of an elongated metal member formed with a pin opening at one end for attachment to the metal truss connecting pin and a flat surface adapted for abutment with the edge face of the wood truss chord, and the other end of the clip is formed with fastener openings for receiving fasteners such as nails, screws or bolts therethrough for attachment to the wood brace member. The surface adjacent said fastener openings is flat for abutment with the side face of the wood brace.
Abstract: A hanger for light series composite trusses having a single upper wood chord and a single lower wood chord joined by a plurality of metal web members by pins. The hanger consists of a pair of mirror image members fabricated from flat sheet metal using standard continuous die, punch-press operations. Each hanger member consists of a horizontal portion and two vertical portions; all at right angles to one another, a tab member and an opening for receiving the truss joint pin.
Abstract: A post base connection device for attachment to concrete to provide resistance to lateral and vertical movement of the post in respect to the concrete. The device is in essence a continuous V-section member which is bent at its mid-point and configured so that the bend mid-point and adjacent areas provide the concrete embedment portions with the upstanding legs thereof continuing upward to encapsulate diagonally opposed corners of the post.
Abstract: A tubular web having a generally circular cross section in the body portion; tapering at its ends in a symmetrical manner and terminating in an end portion having generally flat outside surfaces with the distinguishing characteristic being in the separated end walls. An opening is formed in the separated end wall flat areas for receiving a metal connector pin.
Abstract: A truss structure having upper and lower wood chords joined by tubular metal web members. The chords are formed with a plurality of slots for receiving the ends of the web members. Each slot extends from the inner face to the outer face of the chord. Cross bores extend from the inner walls of the slots laterally toward the edges of the chords. Clevis assemblies are inserted into each slot. The ends of the web members are inserted into the slots and attached to the clevis members by metal pins. Load forces from the webs are distributed to the faces of the wood chords through flanges on the clevis member or connector plates. Load forces are also distributed to the wood chords through the clevis member to the pin and directly to the wood by the configuration of the clevis member.
Abstract: An elongated tubular structural member having an asymetrical end design formed with an opening therethrough for attachment to other structural members as by a pin, rivet, bolt or other cylindrical fastener. At least one end is formed with the bulb section on one side extended to the opening with the bulb section on the other side of the strut terminating at a distance from the opening. The opening is drawn in a direction toward the side having the extended bulb section.
Abstract: The connector elements consist of a pair of identical essentially U-shaped channels with integral flaps providing a compression plate between the lumber end butts and depending legs formed with openings for receiving pins or bolts for attachment to the truss tubular webs.
Abstract: A knee brace to provide lateral resistance at the bottom of glued laminated beams and solid heavy timbers. The brace consists of an elongated strap connected at its mid point to the bottom of the glulam or heavy timber. Legs angled outwardly are connected at their ends to transverse members. Special cut sections in the strap provide tabs running perpendicular to the bottom of the braced glulam or timber. The tabs are held to the side faces of the braced member by nails. The bent tabs and nails in the bottom of the glulam provide the resistance to overturn loads.
Abstract: A truss top-bearing clip forming a part of the end bearing joint assembly for trusses having a pair of parallel wood members and a metal end web such as a tubular flattened end web. The clip is fabricated from flat sheet metal using standard punch-press operations. The ends of the metal truss webs are connected to the clips so that the web load is transferred directly to the clip via metal-to-metal contact. The top wood chords are connected to the clips and bear on the flanges of the clips.
