COMPOSITE PLATE FOR RAIL BRIDGE BALLASTLESS BRIDGE ROADWAY SYSTEM Russian patent published in 2019 - IPC E01D19/12 

FIELD: construction.

SUBSTANCE: composite plate for system of ballastless bridge deck of railway bridge is made in form of parallelepiped with rectangular bases, having central layer made of group of parallel-oriented relative to each other and reinforced with fiberglass fillers and enclosing the middle layer of the external composite shell based on fiberglass with the working surfaces formed on it opposite on the side of the bases of the parallelepiped. Middle layer is made of a group of parallel to each other longitudinally oriented reinforced with fiberglass coating fillers, with formation between adjacent fillers in direction of their longitudinal axes stiffness ribs from fiberglass, connected to inner surfaces of outer shell. Plate on both sides relative to vertical plane of symmetry, transversely oriented to longitudinal axes of fillers of middle layer, has parallel rows of holes for means of attachment on one of working surfaces of plate of rail metal pads and oval holes with walls, reinforced glass-fibre reinforced plastic, to accommodate means to fix plate to span beams of railway bridge. Thickness "h" of outer composite shell of plate on side of working surface intended for arrangement of rail metal pads exceeds thickness "h₁" of the outer shell of the plate on the side of the opposite working surface interacting with span beams of the bridge.

EFFECT: invention implementation ensures creation of composite plate for ballastless bridge rail bridge system reliable in operation at low material consumption of composite plate.
