Abstract: The present invention relates generally to window glazing systems, particularly for high-rise commercial buildings. More specifically, the gasket system of the present invention is directed to a gasket system which can be partially fabricated in pieces off site, then the pieces are heat bonded together on site to thereby provide a substantially unitary gasket construction which is capable of sealing around the perimeter of multiple windows of a commercial building.

Abstract: An expansion joint system for functioning as an expansion joint between concrete sections of a roadway surface or the like. Such roadway surfaces are normally provided with a slot for accommodating thermal expansion and contraction of the concrete and a boxed-out zone for receiving the expansion joint system. The expansion joint system includes a plate and sealants. The plate is provided with a lower or interior resilient winged section inserted into the slot with wings extending exteriorly to frictionally engage the surfaces of the slot and thereby effect centering and preclude the raising of the plate from the slot. The plate is provided with an upper or exterior section including support surface for resting on the boxed-out surface of the cement segments to thereby preclude the plate from dropping into the slot. A stem couples the upper and lower sections of the plate. A sealant then covers the horizontal support and fills in the boxed-out zone of the concrete.
