Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

An anchor holder for concrete decks comprises a body for being inserted into an opening in a metal deck, the body including an outside vertical wall and an opening for receiving an anchor. The body includes arms normally biased extending outwardly from the vertical wall, the arms being collapsible toward the body when the body is inserted into the opening in the metal deck and expanding outwardly after passing the opening to be disposed below the metal deck. A support is attached to the body, the support to engage a top surface of the metal deck to apply an upward force on the body and keep the collapsible arms engaged against an underside of the metal deck when the body is attached to the metal deck.

In certain embodiments, a system includes a curtain wall member and a first curtain wall member mounting apparatus coupled to a first end of the curtain wall member. The first curtain wall member mounting apparatus includes a mounting plate and an arm having one or more projections. The first curtain wall member mounting apparatus engages with a first curtain wall member supporting channel having a vertically-disposed member and a horizontally-disposed supporting member having a receiving-and-retaining member extending from an end opposite the vertically-disposed member. The receiving-and-retaining member engages with a channel adjacent to one or more projections of the first curtain wall member mounting apparatus. The first curtain wall member mounting apparatus is adapted to be rotated into position such that a connection mechanism at a second end of the curtain wall member engages with a second curtain wall member supporting channel to retain the curtain wall member in position.

An assembly for offsite construction of a building, a connector for use in such an assembly, along with a method of manufacture of such a connector, and a method of construction using the assembly. The connector includes first and second buttress elements defining, respectively, a first location portion and a second location portion. The first location portion and the second location portion are configured, respectively, to receive first and second structural elements extending at transverse angles to each other. The first and second buttress elements each has first and second opposite side walls defining an access space between them for a connector to be accessed. The second side wall of the first buttress element and the second side wall of the second buttress element together define a third location portion configured to receive a third structural element extending transversely to the first and second structural elements.

A snap lock system for connecting adjoining countertops comprises: a first locking unit comprising a first surface and an opposite second surface, the second surface being attachable to a first countertop, wherein the second surface has a profile comprising a projection, a first recess, and a second recess; a second locking unit comprising a first surface and an opposite second surface, the second surface being attachable to a second countertop, wherein the first surface has a profile comprising a projection and a recess; the second surface comprises a recess; and a third locking unit comprising a resilient member and a chamfered longitudinal edge, accommodated in a locking groove defined by the second recess of the first locking unit and the recess of the second locking unit. The profile of the second surface of the first locking unit is configured to receive the profile of the first surface of the second locking unit to provide a connection preventing mutual horizontal movement between the first and second locking units. During connection of the first locking unit and the second locking unit, the third locking unit is configured to allow vertical mating of the first locking unit and the second locking unit and, after connection, the third locking unit is configured to prevent mutual vertical movement between the first locking unit and the second locking unit.

Apparatuses for locking PV panels to support structures, e.g., support beams. The support beams may be designed and built with corresponding connection elements, e.g., slots and tabs, which may be used to enable locking and unlocking of the PV panels on the support beams. Once in place, a ferromagnetic flap may be put into an engaged position, thereby closing and engaging a panel locking mechanism. The ferromagnetic flap may be lifted by using a magnet. The magnet may be may be embedded in a suction cup device which is designed to lift and maneuver an object with a relatively flat surface, e.g. a glass pane. The suction cup device may, when suction is applied, be attached to glass covering the PV panels, and thus the suction cup device may be used to move the PV panels.

There is provided a horizontally and vertically extendable building structure module that includes a panel, a structural frame and one or more beams. The panel may be designed to form or set into a floor, ceiling, wall, window, door or any other components that may cover surface of the building. The structural frame may be designed to provide the structural shape and strength and hold the panels. The beams may be designed to connect and align the structural frame. The horizontally and vertically extendable building structure module is configured to build a building structure without additional structural support. Because of the minimized number of components for the building structure, time and cost for building construction may be reduced.

The present invention relates to using interlocking spacer braces between support members to construct wood and metal framed walls, floors and building trusses. Spacer braces have indentations, extensions, fingers that interlock horizontally, vertically or diagonally between support members. The spacer braces can form diagonal and lateral wall bracing, diagonal and vertical chords within building truss with either horizontally or vertical orientations, beams, hold-downs and shear walls. The spacer braces can be installed between wood or metal framing members.

An interconnect system for coupling first and second frame members includes female and male interconnect members. The female interconnect is secured to the first frame member and has defined therein a receptacle. The male interconnect member is secured to the second frame member and defines a protrusion configured for selective axial insertion into, and mating engagement with, the receptacle. The receptacle extends axially between a receptacle opening through which the protrusion is axially received and a receptacle rear wall at which the receptacle terminates. The protrusion terminates at a protrusion tip. The receptacle and protrusion are furthermore configured such that at least one of (a) the receptacle and the protrusion are complementarily keyed in order to prevent relative rotational displacement of the male and female interconnect members when they are in mutual mating engagement, and (b) the protrusion tip is magnetically attracted toward the receptacle rear wall.

Angled coupling including main pass-through coupler to allow first threaded rod to pass therethrough and second coupling extending at angle therefrom to receive second threaded rod. Angled coupling can be used for multiple purposes including, but not limited to, adjusting location of threaded rod, seismic restraints, storm surge restraints and/or providing additional mounting points for support members. Main coupler is configured to be secured to any location on first threaded rod without requiring it to be screwed onto first threaded rod. Main coupler may include first half and second half each traversing length thereof, that can be secured together at desired location on first threaded rod. Main coupler may include upper section having first approximately half of body thereof and corresponding threads and lower section having second approximately half of body (opposite first half) and corresponding threads. Angled coupling is made of high strength material (e.g., steel, cast iron, composites).
