Erdbebensichere Dehnungsfugeüberbrückung.

摘要

A seismic expansion joint cover comprises a pair of elongated frame members (10,12), each of which is adapted to be secured to a building member (16,22), one on one side of an expansion gap (18) and the other on the other side of the expansion gap (18), and each of which has a planar support surface (10a,12a) and an edge (10b,12b) adapted to overhang the gap (18). An elongated cover member (26) spans the expansion gap (18) and is supported on the support surfaces (10a,12a) of the respective frame members (10,12) for sliding movement of the frame members (10,12) relative to the cover member (26). A hold-down assembly (30) resiliently holds the cover member (26) in engagement with the support surfaces (10a,12a) of the frame members (10,12). A multiplicity of deflector members (50) on the cover member (26), each having an inclined surface (50a) that is engageable by the overhanging edge (10b,12b) of one of the frame members (10,12) upon narrowing of the expansion gap (18) during a seismic event, is adapted upon such engagement to displace the cover member (26) against the bias of the hold-down assembly (30) to a position in which its side edges are not susceptible to contact with any portions of the frame members (10,12) or the building members (16,22) upon further narrowing of the expansion gap (18). Gaskets (60) are detachably connected to the side edge of the cover member (26) and to the frame members (10,12).
