摘要
The present invention relates to a watertight expansion joint device for a bridge. The present invention is to improve an effect of preventing the leak of rainwater by allowing both ends of a drain sheet to come in contact with a wall of main frames of the expansion joint device. According to the present invention to achieve the objective, the expansion joint device comprises: a pair of main frames (10) having a finger plate (20) on the top; anchors (30) arranged on the outer surface of the main frames (10) to be buried in a bridge slab (1); and a drain sheet (40) arranged between the pair of main frames (10). The expansion joint device additionally comprises: vertical pressing plates (50) coupled to both main frames (10) by a bolt to press the drain sheet (40); and support protrusion parts (10) separately protruding from the lower part of the inner surface of the main frames (10) to support the vertical pressing plates (50).;COPYRIGHT KIPO 2016
