Abstract: An expansion joint system for bridging an expansion joint gap between two spaced-apart underlying stair structures. The expansion joint system includes a movable plate that is connected to a fixed plate through a hinge. The hinge connection permits the movable plate to move in response to thermal movements and seismic events that causes the width of the expansion joint to open to a greater width or close to a smaller width. Following the seismic or thermal event, the hinge connection automatically returns the movable plate to its original position.

Abstract: A backer rod adapted for forming a fire-resistant seal within a construction joint. The backer rod may include an elongated tube defining a total assembly volume and a hollow interior, and a core disposed within the hollow interior. The tube is formed of a combustible foam plastic which disintegrates when exposed to fire. The core material is expandable when exposed to fire, such that the core has an intumescent expansion factor sufficient to expand to a volume beyond the total assembly volume. The backer rod may be press fit into a void between two surfaces to a depth. A sealant layer may be formed within the void. When exposed to fire on a side opposite the sealant layer, the external shell disintegrates, the core expands within the void in a direction away from the sealant layer, and a fire-resistant barrier is formed within the void between the surfaces.

Abstract: A composite building system includes open webbed joists with lower flanges aligned parallel to one another and spaced at a distance to create longitudinal block accepting channels. The channels are sized to accept standard masonry blocks. Masonry blocks and compressible spacers of a height less than the height of the masonry blocks are alternately laid in the longitudinal channels such that rows of blocks are aligned transversely across the channels thereby creating a grid-like pattern of blocks separated transversely by the joists and longitudinally by the spacers. Transverse grooves are created above the spacers and between adjacent blocks in each channel. Longitudinal troughs are created between adjacent blocks across each channel. Wire reinforcement is laid in the transverse grooves and grout is poured to fill the transverse grooves and the longitudinal troughs to form an integral steel reinforced concrete structure having a substantially planar top surface.
