A concrete fillable steel joist includes a generally U-shaped member and a top chord. The generally U-shaped member has spaced apart webs and a bottom chord. The top chord is operably attached to the U-shaped member. The top chord has a plurality of spaced apart top chord holes. The U-shaped member and the top chord define a volume that is fillable with concrete when opposed ends of the U-shaped member have joist ends operably attached thereto. The joist ends may be a pair of end plates. Alternatively, the joist ends may be structural members. A concrete fillable steel joist system includes a plurality of spaced apart concrete fillable steel joists, and metal decking. The metal decking is operably attached between the spaced apart steel joists. The concrete fillable steel joist and the metal decking are configured to receive concrete.

A modular system for the dry building of structures for constructions, such as walls, floors, balconies, roofs or the like, includes a plurality of planar modular beams that define a respective plane and that are mutually jointed, and a plurality of planar panels anchored thereto at least at or in proximity of the end portions of the same planar modular beams.

A lateral force resistance system for a building is provided wherein a portal frame is constructed with a lapped connection between the supported structural member and the supporting structural member and the supporting structural member is made with an elongated member that spans the width of the supporting structural member and the height of the supporting structural member.

A modular system for the dry building of structures for constructions, such as walls, floors, balconies, roofs or the like, includes a plurality of planar modular beams that define a respective plane and that are mutually jointed, and a plurality of planar panels anchored thereto at least at or in proximity of the end portions of the same planar modular beams.

A fastening system for joining a first structural member end-on to a second structural member is provided. The fastening system includes a latching device comprising at least one eccentric rotatable part and at least one generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. The latching device is fixed to an end of a first structural member and the receiver is fixed to a side of a second structural member. The first structural member may be joined end-on to the second structural member by positioning the latching device on the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together.

The coupler adaptor mounts on a rectangular extrusion vertical end to allow one or more accessory connections to be affixed to the vertical rectangular extrusion. A further object is to allow multiple horizontal rods to be mounted in parallel from a single vertical rectangular extrusion. The coupler adaptor clamps onto the vertically configured rectangular extrusion via a stable clamp and a slidable clamp. The slidable clamp and the stable clamp are pulled together along the length of the coupler adaptor body via the screw tightener. The channel openings and the channel walls are mated with the grooves on the rectangular extrusion creating a clamped, friction mating with the rectangular extrusion such that the coupler adaptor is securely fastened to the rectangular extrusion.

A splice joint of a main girder of a crane, the main girder including at least two longitudinal main girder parts to be connected to each other by their ends and each having a central web which includes at least one web plate, longitudinal upper and lower flanges, the lower flange protruding from the central web to both sides thereof. The splice joint includes a plate-like tongue-and-groove joint, the tongue-and-groove joint including a tongue fixed to the central web of a main girder part, and a groove fixed to the central web of a second main girder part; and a lower flange joint receiving the bending forces of the splice joint. The tongue-and-groove joints are arranged reversed in relation to each other, and the location of the tongues and grooves on opposite sides of the web is reverse in relation to each other.

Embodiments of a framing assembly including modular connectors for interconnecting components of the framing assembly are disclosed.

An end panel bracket useful with a building panel system is provided. The end panel bracket comprises a base, a middle portion extending from the base, a shelf extending from the middle portion, a notch, and a ledge.

A balcony includes a balcony assembly and a structural post and outrigger system. The structural posts provide structural support for buildings and include the outriggers that extend substantially perpendicularly from the structural posts to a location where the balcony assembly will be installed. The outriggers include a tube or beam and an end plate on an end of the beam distal from the structural post. The balcony assembly includes at least one long beam, a platform, and a locking mechanism on an end of the long beam. The locking mechanism includes a channel for receiving and securing the end plate of the outrigger. The balcony assembly is secured to the outrigger using fasteners.
