A wheeled conveyance straddles and squeezes a parapet or similar vertical wall from both the inside and outside vertical faces. Side wheels may be adjusted to be closer together or farther apart to accommodate the thickness of the wall being straddled. The conveyance traverses the parapet along the top edge, and at least one fastener driver suspended from the carriage faces one or both of the inside and outside vertical faces at some preferably adjustable distance below the top edge of the parapet. While the conveyance traverses the parapet, an actuator selectively and repeatedly actuates the fastener driver(s). Various sensors and controls are provided that permit the speed, fastener spacing, and travel distance to be adjusted. Position awareness and visual, auditory, and radio communications may optionally be employed.

Wall systems and buildings having such wall systems are disclosed. Such wall systems include parametric mullions each of which is constructed from a plurality of interconnecting components so that the wall systems may be disposed much closer to the building frame than conventional wall systems. Such wall systems may include panels disposed to form convex or concave facades. Such wall systems may also include decorative features superimposed over one or more panels or extending outward from the facade surface. The parametric mullions may be formed into trusses which may be used as part of a wall system or independently of such wall systems.

A metal blocking with coping with cleat having a coping cap with a cap top flange, and first and second side flanges defining first and second channels respectively at respective ends; and a coping cleat having first and second top flanges, a corner anchoring flange, and an intermediate anchoring flange. The first channel is defined by a first exterior cleat strip, a first base cleat strip, and a first interior cleat strip. The second channel is defined by a second exterior cleat strip, a second base cleat strip, and a second interior cleat strip. The first side flange has a first predetermined height and the second side flange has a second predetermined height, wherein the first predetermined height is shorter than the second predetermined height.

A roof edge blocking with cleat having a blocking assembly with a top flange, a first lateral flange, a second lateral flange, an anchoring flange, and a locking tab; and a cover assembly having a cover top flange, an angular wall, a side flange, and a channel, whereby the cover assembly mounts onto the blocking assembly. The first lateral flange perpendicularly extends from the top flange. An upper wall and a lower wall of the anchoring flange extend perpendicularly from the first and second lateral flanges respectively, and are substantially parallel to the top flange. The upper wall and the lower wall are joined at the anchoring flange to define an elongated aperture. The locking tab extends outwardly from the second lateral flange defining a first predetermined angle. The first lateral flange has a first predetermined height and the second lateral flange has a second predetermined height.

An expansion joint having three axes of expansion for roof to wall and roof to roof applications. An expansion joint with roof to wall applications preferably includes a continuous cleat, a curb rail, a condensate seal, a formed cap, a sliding surface plate and a plurality of retainer plates. The continuous cleat slides vertically relative to a wall and horizontally relative to a roof curb. The continuous cleat slides vertically relative to the formed cap. An expansion joint with roof to roof applications preferably a continuous cleat, a formed cap, a curb rail, a Z-curb rail, a condensate seal and a plurality of retainer plates. The continuous cleat slides vertically relative to a fixed curb wall and horizontally in two axes relative to a free roof curb.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks can be used in place of wood blocking for roof assembly applications such as installation of a drip edge or wall coping; or in expansion joints. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

A roof edge capping assembly for directing water to a roof of a building includes a housing that defines an interior space. The housing comprises steel so that the housing is rigid. The housing has a top, a bottom, opposing ends, a first side, and a second side. The bottom is configured to couple to an upper end of a wall, such as an exterior concrete wall of a building. The first side and the second side are positioned proximate to an outer face and an inner face of the wall, respectively. The first side is dimensionally taller than the second side. The top extends downwardly from the first side to the second side. The top is configured to direct water that contacts the top to a roof of the building and to prevent the water from penetrating the upper end the wall.

The adjustable coping cap is a prefabricated coping cap that it adjustable to the width of a wall. Specifically, the width of the adjustable coping cap is readily adjustable for use from a minimum wall width to a maximum minimum wall width that is up to three inches wider than the minimum wall width. The adjustable coping cap comprises a first wing, a second wing, and an adjustable plate.
