<p>The present invention relates to an expansion joint which provides a flexible seal between two spacedapart confronting sections of similar structures such as roadway slabs or the like. The expansion joint includes at least one assembly adapted to be secured to each section of the structure. The assembly has an upper elongate beam portion and a lower elongate and fixed forming bar portion. The beam portion and the bar portion are spaced apart to provide an elongate channel. The channel defines a mouth which opens towards the gap between opposing assemblies. The joint includes a sealing element for spanning the gap between the assemblies. The sealing element includes a flexible intermediate portion with two laterally extending elongate flanks. At least one clamp member lockingly engages the flanks to each of the confronting sections. The clamp member, together with the flanks, are insertable into a channel defined by the upper beam and lower forming bar. The clamp member is secured between upper beam and lower forming bar and the clamp and the flank are secured together by compressive engagement between the clamps and the flanks.</p> |
