A stud or joist sensor device and associated sensing method using a ratio of capacitance measurements from a plurality of capacitive sensing elements. The device locates a feature of an object or discontinuity behind a surface or wall, such as an edge and / or a center of a stud behind the surface, a joist under a floorboard, a gap behind sheetrock, a metal conductor behind a surface or the like. The device may be moved over a surface, thereby detecting changes in capacitance. The change in capacitance is due to the effective dielectric constant caused by the passage over an object such as a stud. When two capacitive sensing elements provide equivalent capacitance measures, the device is over a centerline of the stud. When a ratio of the capacitance measurements equals a transition ratio, the device is over an edge of the stud.

Electrical fixtures, such as junction boxes or recessed luminaires, include mounting brackets that support the fixtures from structural members while fasteners, such as screws or nails, are driven through the mounting brackets, thereby facilitating mounting the fixtures. Each of the mounting brackets has a general U-shape that includes at least three generally planar sides. The top side is generally perpendicular to the other two sides, and the top side connects the other two sides and together. The three sides define (in cross-section) a structural member receiver opening. An inside dimension of the structural member receiver opening is such that bracket fits snugly around at least a portion of a commonly sized wood or metal structural member, such as a furring strip or joist, used in ceiling construction. In one embodiment, two of the sides of the structural member receiver opening define an acute dihedral angle to hood around the edge of a metal furring strip.

According to existing methods of frame building construction, a concrete foundation is formed on which wooden floor joists are laid. Walls are constructed on the foundation and floor using wooden wall studs, and a roof is constructed on the walls using wooden rafters, beams and trusses. These methods require skilled carpenters and high quality wood materials, both of which are increasingly expensive. There is therefore a need for a system for framing houses or other buildings which uses prefabricated steel framing and which is quick and easy to construct. The invention provides a prefabricated system for framing a complete building on a foundation. Folding telescopic framing units are used for vertical partitions and horizontal floor panels. The invention therefore provides a prefabricated system of framing units forconstructing a building comprising: a) proving a foundation; b) securing vertical beams having open upper ends to the foundation at spaced locations; c) securing horizontal beams between the upper ends of the vertical beams; d) erecting and securing folding, telescopic floor joists on the foundation; and e) erecting and securing folding, telescopic roof trusts at spaced locations on the horizontal beams. The invention also provides a framed building comprising: a) a foundation; b) vertical beams having open upper ends secured to the foundation at spaced locations; c) horizontal beams secured between the upper ends of the vertical beams; d) erected folding, telescopic floor joists secured on the foundation; and e) erected folding, telescopic roof trusts secured at spaced locations on the horizontal beams.

This mounting clamp is used as a truss adapter for support of fixtures, electrical and otherwise, from a truss ceiling. The clamp comprises a plate suspended by a pair of upstanding arms, each of which is formed by a bolt connected to an inverted U-shaped rectangular hanger member. The hangers and their associated bolts are inserted upwardly between the spaced beams of a bar joist from below and then the hangers are rotated 90 degrees before they are lowered into place to rest on both of the spaced beams, spreading the load, as the hanger arms are tightened to the plate. The plate carries a connector for mating to the object to be mounted. Leveling screws provide adjustment for orienting the mounted object. A vibration damping pad is included when appropriate. Variations of the clamp may be used in wall or parapet mount configurations.

A novel system for constructing smooth-faced metal framing and novel tracks and track connectors therefore. The system and connectors of the present invention utilize metal framing tracks that demonstrate a U-channel configuration having a base, sidewalls with at least one recess channel formed longitudinally therein, and marginal lips that extend inward from the sidewalls. A variety structurally related connectors, comprising at least a connector body, lip or base flange, and two lip receiving grooves, are described. These connectors are capable of interconnecting metal framing performing all framing functions including, without limitation, floor and ceiling joists, top and bottom plates, roof rafters, roof rims, window sills, trusses, headers and wall studs. The connectors lock into place within the track and are secured from the inside using fasteners applied into the non-surface aspects and / or recess channels of the track. The track connectors demonstrate three dimensional rigidity and a box-like fit within the metal framing tracks to form joints that are strong, durable and precise. The framing system using the track connectors of the present invention leaves the outside surfaces of the framing members smooth and continuous, without protruding fastener heads or interruptions of any sort. The resulting smooth outside surfaces can be covered much more easily and inexpensively than the uneven and generally awkward outside surfaces presently encountered in metal framed structures. The manner in which the connectors lock within the tracks promote their safe and efficient installation. The system and connectors of the present invention enables an entire structure to be framed using one type and size of metal framing track cut to appropriate lengths on site.

A device for affixing a decking member to a joist includes a jig body positionable atop a pair of spaced-apart decking members positioned atop a joist. The jig body has an angled bore having a bottom end extending through a bottom face of the jig body, the bottom end of the angled bore in communication with the space between the decking members. The angled bore defines a centerline extending through the space to a position on the side of the first structural member. The angled bore is for receiving a fastener drivable therethrough into the first structural member's side face, through the first structural member's bottom face, and into the second structural member's top face.

A deck clip comprises a generally vertically extending leg; and a pair of arms extending from an upper edge of the leg. Each arm is configured for insertion into a slot of a deck board and presents an enlarged lobe. When the deck clip is screwed to a deck joist, the lobes grip the deck boards and hold them tight against the joist. The shape of the lobes increases the gripping force between the lobes and the deck boards as adjacent boards are hammered or otherwise pushed together. The lobes facilitate the gripping of the boards and help maintain the desired gap between adjacent boards for the life of the deck.
