FIELD: construction.
SUBSTANCE: device for connection of a reinforced concrete roadway slab with beams of a railway bridge span includes a connection element in the form of a steel tee, to the shelves of which there are Nelson pins welded, built into the body of the reinforced concrete roadway slab, and elements of tee fixation to the main beams of the span in the form of paired clip angles and high-strength bolts. The steel tee is arranged in the form of a central element closed along the contour and two side U-shaped elements joined with its walls to the central element closed along the contour. Nelson pins built into the body of the reinforced concrete roadway slab are fixed to tee shelved along the entire length of the central element closed along contour and side U-shaped elements.
EFFECT: higher reliability and strength of connection of a reinforced concrete roadway slab with main beams of a span.
