1. Track junction for expansion joints in railway bridges with an elastic expansion profile (2) which extends along a track joint (F) and is held on its edge region on both sides of the track joint by means of a rigid edge profile (3, 4) fixed on a base (21a, 21b), and with a support arrangement which supports the expansion profile from below, characterised in that during assembly the space between the two edge profiles (3, 4) ; the support arrangement is constructed in the form of at least one holding plate (6; 6a, 6b), at least one holding plate (6; 6a, 6b) being arranged so as to be fully accessible from below inside the gap (S) which is constructed between the bases on both sides of the track joint ; at least one holding plate (6; 6a, 6b) is releasably mounted on a support element (7, 14) ; and the upper face of the expansion profile (2) is covered by a cover plate (14) which rests laterally on top of the edge profiles (3, 4). |
