CONSTRUCTION OF BRIDGES, {ELEVATED ROADWAYS} OR VIADUCTS; ASSEMBLY OF BRIDGES (bridges extending between terminal buildings and aircraft for embarking or disembarking passengers B64F 1/305; {tracks for special kinds of railways E01B 25/00; culverts E01F 5/005})
Definition statement

This place covers:

Spanning structures, e.g. railway bridges, for allowing traffic, e.g. pedestrians, automobiles, trains, to travel across naturally occurring obstructions, e.g. gorges, bodies of water, or over man-made obstacles, e.g. roads, canals. Each spanning structure including obstruction or obstacle traversing structure that provides a passageway for traffic and links or is held up by:

  • one or more supports supported by the surface of the earth, e.g. arch-type bridges with end supports, lift-type brides with single main support, portable-type bridges with wheeled support; or
  • one or more buoyant supports which contact a fluid type obstruction or obstacle being crossed, e.g. floating-type bridges with buoyant support.

Spanning structures used for purposes other than carrying traffic, e.g. aqueducts, that are structurally similar to spanning structures for traffic and traverse the same types of obstructions and obstacles.

Specially adapted components for use in spanning structures, e.g. suspension cable clamps.

Accessories or ancillary devices specially adapted for use with spanning structures. e.g. drawbridge gates that are actuated when the span moves.

Methods specially adapted for constructing spanning structures, e.g. specially adapted bridge erecting or assembling techniques.

Methods specially adapted for restoring damaged, e.g. replacing dilapidated decking, or structurally augmenting, e.g. strengthening existing component to allow increased traffic load, existing spanning structures.

Methods specially adapted for demolishing or dismantling spanning structures.

Apparatus specially adapted for constructing, restoring, augmenting, or demolishing spanning structures.

Special rules of classification

Relevant information with respect to the material constitution of bridges, i.e. wood, concrete, stone or stone-like, metal and plastic are additionally classified in E01D 2101/00.

Bridges in general (characterised by their structural type E01D 4/00 - E01D 15/00)

Special rules of classification

Bridges having a cross section like e.g. I-beam, T-beam or boxgirder type. E01D 4/00 - E01D 15/00 take precedence.

Truss-type bridges
