Abstract: A vibration resistant expansion joint is provided. The expansion joint includes a sustaining pedestal (1) which is formed from two L-shaped members (111 and 112). A plurality of shim assemblies (12), each containing a bifurcated tooth-like shim (121), are pivotally joined to the sustaining pedestal (1). Additionally provided is a foundation (3) formed of two L-shaped side members, each side member having a slide surface (33, 34) formed along a bottom edge thereof. A stepped bench unit (2), formed of a pair of benches, is slidably mounted on foundation (3).

Abstract: An expansion joint in which by means of movability of expansion shim assemblies in a sustaining pedestal and a stepped bench unit formed of a pair of benches at different elevation disposed beneath the sustaining pedestal so as to withstand vibration of roadway or bridge and instantly rescue the roadway or bridge from collapsing.

Abstract: A bridge joint for use with a railroad track having standard rail sections with flanges. The bridge joint includes a fixed point having a forward integral accepting portion with a point and flanges rearward of the accepting portion. The joint also has a moveable body having a forward interface portion adapted to be slidingly accepted in the accepting portion. The moveable body has a notch adapted to accept the point. Clamping lugs are positioned on the accepting portion and the interface portion. The fixed point and the moveable body are clamped to base plates and quick release fasteners are positioned to engage the flanges of the fixed point, moveable body, and a flange of each of the standard rail sections and secure all to the base plates.

Abstract: An energy efficient deck framing system and method is disclosed. In a deck framing system having structural framing members that support a deck panel structure, individual deck panels are inserted between pairs of the framing members. Supporting rods extend downward through the top of the framing members and are provided with a support nut that is sized to maintain the framing member in a supported fashion. An insulating subassembly is provided having an insulating washer interposed between a conventional washer or a secondary nut and the top of the framing member, and an insulating retainer clip received in the lower portion of the top of the framing member and the support nut. The insulating retainer clip is constructed and arranged to be securably received within the contours of the framing member.
