Abstract

A fire rated glass flooring system having blast and/or seismic loading resistance, comprising: (a) a plurality of glass flooring units (100a, 100b), each unit comprising a first layer (116) of glass and a second layer (118) of glass, the two layers being positioned one above the other and separated by one or more load transferring means (120a, 120b), wherein the first layer of glass is a structural glass and the second layer of glass is a fire rated glass, and having an upper surface and an edge comprising a load-transferring means of the one or more load transferring means; (b) one or more beams (112), arranged, in use, to support the units, wherein, at a boundary between two adjacent flooring units, the two flooring units are arranged, in use, to be secured to a beam of the one or more beams; and (c) one or more expansion joints (110), each arranged, in use, at the boundary between two adjacent flooring units. Each expansion joint comprises: (i) two clips (200a, 200b), each clip being arranged, in use, to be connected to the load-transferring means in one of the two flooring units; (ii) a resilient seal (202) arranged, in use, to sit between the two clips, the seal extending substantially to the upper surface of the two units; and (iii) a drainage means (204), the drainage means being located substantially below the seal and the two clips, and arranged, in use, to capture and drain away any liquid which passes the seal.
