Abstract: A curtain wall renovation system for an exterior of a building includes a plurality of new mullions attached to a top surface of a first floor slab of a first floor and extending downwardly external to the building and below an outer edge of the first floor slab, and a temporary weather shield system assembled in a second floor below the first floor and inset from an outer edge of a second floor slab. The temporary weather shield system includes a plurality of dry anchoring devices fastened to a top surface of the second floor slab, a plurality of temporary mullions supported on the top surface of the second floor slab and each including a bottom and a top, and a plurality of reusable panels, each reusable panel being secured to two laterally adjacent temporary mullions of the plurality of temporary mullions.

Abstract: A curtain wall mullion anchoring system that does not require adjustability among the anchoring system components and the mullion to account for construction tolerance. The anchoring device can be accurately installed on a cured concrete floor slab at the proper in-and-out and left-and-right positions. A mullion connector is engaged with the anchoring device and the mullion to transfer reaction forces on the mullion to the building structure via the anchoring device. The mullion connector is slidably engaged with the mullion such that the mullion connector can slide along the length of the mullion and will be placed at the proper up-and-down position by simply sliding the mullion connector down the mullion to the anchoring device on the concrete floor slab.

Abstract: An exterior wall panel with a vented insulated glass unit with the air space between the glass panes pressure equalized with exterior air. The vented insulated glass unit is configured to eliminate the requirement for a perfect seal around the insulated glass unit perimeter, limit water condensation within the insulated glass unit, limit water infiltration, and maintain thermal insulation performance.

Abstract: Curtain wall mullion anchoring systems for resisting dead load and negative wind load, and that permit three-way construction tolerance adjustments. The mullion anchoring systems include an anchoring device secured to a building structural element and attached to a mullion connection bridge, which is connected to a mullion connection clip, which is connected to a mullion. Uplifting forces on the anchoring device may be significantly reduced or even eliminated by transmitting dead load under negative wind load conditions from the mullion to the anchoring device at a point over the inside of a concrete floor slab, such that the dead load counteracts any uplifting force generated by the negative wind load.

Abstract: Exterior opaque hidden frame wall units and systems combining facing plates and composite insulated panels in a pressure-equalized Airloop system, permitting an opaque hidden frame wall unit without the need for intermediate stiffeners for resisting wind load, without exterior aesthetic problems associated with composite insulated panels, without a separate interior wall, and without interior condensation problems. Also provided are exterior opaque hidden frame Airloop wall units and systems with the air seal being isolated from the water seal on an offset vertical plane and away from the interior surface of the facing plate.

Abstract: An Airloop window wall system for use in modular construction technology. The Airloop window wall system is designed for installation of wall panels from the exterior of a modular unit. Additionally disclosed are horizontal butt joint panels to cover the horizontal butt joints between vertically-adjacent modular units, and Airloop vertical butt joint panels to cover vertical butt joints between horizontally adjacent modular units, while providing a continuous Airloop system for water-tightness performance.

Abstract: Hidden frame airloop wall systems. The airloop wall systems disclosed here provide for systems that may accommodate various types of glass, including vision glass and spandrel glass. In some examples, the same airloop wall unit may accommodate both a vision glass panel and a spandrel glass panel. The disclosed airloop wall systems permit the use of glass of varying thickness, while at the same time presenting a consistent surface. Additionally, the window frame will be hidden from exterior view after the airloop wall system is installed.

Abstract: An intermediate divider system for an exterior wall unit. The intermediate divider system allows for flexibility in aesthetic design of the exterior wall grid line pattern, while maintaining both wind load resistance and water-tightness performance.

Abstract: A mullion connection system for resisting wind load reactions using a connection clip structurally engaged with a mullion without a hole or a fastener penetrating into the mullion surface. The connection clip can undergo stress-free vertical sliding relative to the mullion along the entire length of the mullion without impairing the structural connection strength; therefore, the building construction tolerance in the vertical direction is eliminated as a design consideration of the curtain wall system. The design also eliminates the need for pre-fabricating mullion holes for the connection locations. The design does not require the pre-determination of the elevation of the connecting point and thus is most beneficial for a curtain wall renovation project where the available locations in the building structure for structural connection cannot be determined prior to the demolition of the existing wall.

Abstract: A method and apparatus for efficiently forming individual building units is provided, generally includes providing a plurality of molds, each capable of simultaneously forming a plurality of building units. Batches of cementitious slurry are individually mixed in order to control the density of each building unit formed. The ingredients are individually measured and combined into the mixing device. The cementitious slurry is then conveyed or transported and poured into one of the molds. The method provides the ability to control the amount of cementitious slurry in each batch in order to control to the extent possible the quantity of cementitious slurry poured into each mold and the ability to precisely control the dimensions of each building unit produced.

Abstract: When assembled to a building support structure to form a curtain wall system of adjoining panels, a preferred embodiment of the enhanced airloop wall system as shown in FIG. 2 comprises panel frame segments that, when assembled, form interconnected inner and outer airloop segments that separate and improve water seal and air seal functions and improve sealing performance, a circuitous path (e.g., “A”) at an enlarged air opening into an airloop to pressure equalize and limit water entry into the airloop, a two point fastener support of each panel assembly to allow interfloor deflections under seismic or other loads without excessive loads on the panel assembly, a structural hook-like protrusion for resisting building outward loads on panels separate from fasteners, a splitter in a drainage cavity in the outer airloop that creates a dual drainage path and a surface upon which droplets can collect.
