Abstract:
This invention relates to an improved wall for resisting lateral forces imposed on a building that incorporates the wall. Specifically, this invention relates to a wall in a light-frame building having within it a sub-component specifically designed to resist lateral forces imposed on the building such as those caused by an earthquake or by wind loading. The wall is formed with a bottom plate that rests on the underlying structural component of the building. A plurality of vertically-disposed studs connect to the bottom plate, and a top plate is supported by and connects to the vertically-disposed studs. A shear-resisting assembly connects to the top plate and the underlying structural component. The shear-resisting assembly has top and bottom struts and first and second chords and a planar shear resisting element connected thereto.
Abstract:
A hold-down for securing first and second support members in a portion of a building to an anchoring device extending from another portion of the building. The hold-down may include a first flange having securement apertures therethrough configured to receive fasteners adapted to secure the first flange to the first support member. A second flange may have securement apertures configured to receive fasteners adapted to secure the second flange to the second support member. A base may connect the first and second flanges and have an aperture sized and positioned to receive the anchoring device therethrough. The first and second flanges may be configured to be loaded substantially exclusively in tension by the anchoring device.
Abstract:
The present invention relates to horizontal, vertical or angularly disposed diaphragms which resist structural forces. Specifically, the present invention relates to an improved mechanical connection between a structural panel and the framing members that support the structural panel forming a diaphragm. The connection includes: a structural panel having a distal side, a proximal side, and a plurality of edge faces; a frame consisting of a plurality of framing members disposed in registration with the proximal side of the structural panel near the edge faces; a plurality of perimeter fasteners connecting the structural panel to the framing members; and clips or perimeter edging members for reducing bending of the perimeter fasteners attached to a substantial number of the perimeter fasteners. The clips or perimeter edging members for reducing bending of the perimeter fasteners act when lateral forces are imposed on the building structure of which the diaphragm is a part.
Abstract:
A snugging connection and method for moving a movable structural member into closer contact with a stationary structural member in which a connector for joining the two structural members is formed with a snugging member which is activated by driving a fastener through an elongated opening in the connector; snagging an end of the snugging member; causing the snugging member to pivotally rotate and move the connector in a direction generally in the direction of the longitudinal axis of the elongated opening. The two structural members are thus brought closer to each other and may cause the connector to be in tension.
Abstract:
A jacketing system for cylindrical storage tank structures of the type used for oil, water, etc., wherein vertically disposed insulated panel sections are affixed to wire cable members or the like on the outside walls of the tank structures and improved articulated fasteners are provided for securing the panel sections to the wire cable members.
Abstract:
Screw fasteners are used to connect multiple trusses in side-by-side relationship. The screw fasteners join truss wood members which are in edge to edge relationship with the screws being driven through the edge of each wood member. The screws may be knurled screws as described in U.S. Pat. No. 6,109,850; lag screws, or standard screws. The connection may also join wood board members in edge-to-edge relationship when bending of the wood members is limited by a restraining structure.
Abstract:
A holdown strap connection including a sheet metal holdown strap connector for joining a generally vertical frame member such as a post or stud to a concrete foundation made from one piece of sheet metal that installs easily to otherwise identical left and right corner vertical frame members with the same load values for resistance to uplift forces. The one-piece, in-line sheet metal holdown strap connector includes a foot section embedded in the concrete, a transition section connected to the foot section and an elongated strap section integrally connected to the transition section that extends in registration with the side face of a vertical frame member and attaches thereto.
Abstract:
A building frame connection including a metal connector for attaching plated wood trusses to wood top plates or mudsills in building structures consisting of a single member constructed from sheet metal including a base member for slidably receiving the bottom edge of the truss, a sail member formed with slotted nail openings and positioned in face to face registration with the side face of the truss, a pair of stabilizer members connected to the sail member, a pair of holding members connected by nails to the stabilizer members and affixed to the wood top plates or mudsills and nails inserted through the slots in the sail member and into the truss member enabling substantial horizontal relative movement of the truss with respect to the top plate but preventing uplift of the truss relative to the top plate. In a preferred form of the invention, projections protrude from the front face of the sail member preventing seating of the nail heads against the front face of the sail member.
Abstract:
A tension tie for holding a wood frame member subject to a design load in tension to a wood or concrete member. The tie is connected to the wood frame member by nail fasteners and to the concrete or wood member by an anchor bolt. The tension tie is constructed from sheet metal and includes an elongated strap member which is connected to a foot member by means of a rivet. The foot member is characterized by a single sheet continuous seat member connected to side members which in turn are connected to overlapped back members joined by the same rivet used to connect the foot member to the strap member.
Abstract:
A clip for retaining sheet metal roofing or siding panels on a structure, while providing for thermal expansion and contraction of the panels, is made from a single piece of sheet metal. The metal is cut and bent so as to form a base portion having panel supporting embossments, and an upright portion which has panel retaining bulbous projections adjacent the top edge. Preferably there is an even number of these bulbous projections and they alternate projecting to opposite sides of the upright portion. Most preferably, the clip is made of stainless steel when it is intended for use with aluminum panels. The clip is adapted to have its base portion affixed to a building structure and its upright portion enclosed within the seam joint between two adjacent metal roofing or siding sheets which are formed over the bulbous projections of the clip.
