Abstract: A bracket for securing insulation and/or a stiffener relative to a mullion or transom having a given width. The bracket includes a pair of legs extending from a bridge to define a receiving channel having a width equal to or smaller than the given width. The bracket can be attached to the mullion with friction. At least one of the legs defines a first receiving slot configured to receive a clip leg of a respective clip configured to engage the insulation, and an optional second receiving slot configured to receive a face of the stiffener. In an alternative configuration, the bracket can be attached to a side of the mullion via an existing anchor attachment near the floor line so that the anchor attachment does not interfere with the bracket.

Abstract: A firestop system for fire stopping a bus duct that passes through an opening in a marine deck or a marine bulkhead includes a boot seal wrapped around the bus duct housing. The boot seal has a top end attached to the bus duct, and a bottom end attached to the division. The boot seal is made of flexible material to allow for movement of the bus duct relative to the division due to vibration. The boot seal may be made of a thermal barrier wrap or other high-temperature insulating mat materials to allow heat generated under normal condition to escape while providing firestopping and temperature resistance under fire exposure conditions. The firestop system may also have a gasket positioned between the bus duct and the boot seal to accommodate irregularities in the outside surface of the bus duct housing.

Abstract: Assembling a multi-story building using a prefabricating a curtain wall assembly (CWA) involves assembling a structural frame and preparing the frame to receive a thermal insulation panel in a spandrel area. A thermal insulation panel is then supported in the spandrel area using a flange plate of a plurality of brackets that are secured to the frame. The thermal insulation panel is engaged or secured using one or more clips which retain the panel to the frame. The process continues by attaching the CWA which has been prefabricated to a floor slab on the building to form a portion of the building curtain wall.

Abstract: A bracket for securing insulation and/or a stiffener relative to a mullion or transom having a given width. The bracket includes a pair of legs extending from a bridge to define a receiving channel having a width equal to or smaller than the given width. At least one of the legs defines a first receiving slot configured to receive a clip leg of a respective clip configured to engage the insulation, and an optional second receiving slot configured to receive a face of the stiffener.

Abstract: A dock handrail gate includes a base plate installable on the surface of the dock and a post mounted to the base plate perpendicular to the base plate. The handrail also has a rail that attaches to the top portion of the post and extends horizontally and inclines downwardly at an angle inwardly towards the post and further attaches to the bottom portion of the post. The handrail may also have an inner tube that includes an inner sleeve to allow the post and the rail to be lifted and rotated to lock into one or more positions.

Abstract: A firestopping sleeve positionable usually in walls which is self-adjusting and includes a sleeve defining an access corridor extending longitudinally therewithin with at least one firestopping pad positioned therein. The sleeve has an access corridor extending therethrough for receiving wall penetrating cables which are firestopped therearound by the pad. A projecting block is attacked to the pad for providing self-adjusting and sealing capability of the device, to prevent air or smoke leaks around the cables.
