Composite bridge deck and bridge construction
A bridge construction having a bridge support or abutment and a bridge deck supported thereon. The bridge deck includes a composite panel with a top plastic skin, a bottom plastic skin and a core arranged between and attached to the plastic skins. The bridge deck also includes an edge beam extending along at least one edge of the composite panel and resting on the bridge support. The top plastic skin has a protruding part which protrudes laterally relative to the core and the bottom plastic skin. The protruding part of the top plastic skin extends over and is attached to a top side of the edge beam, and both the core and the lower plastic skin extend laterally up to a front side of the edge beam.
1. A bridge deck comprising
a composite panel with a top plastic skin, a bottom plastic skin, and a core arranged between and attached to the plastic skins, and
an edge beam extending along an edge of the composite panel,
wherein the top plastic skin has a protruding part which protrudes laterally relative to both the core and the bottom plastic skin,
wherein the protruding part of the top plastic skin extends over and is attached to a top side of the edge beam, and wherein both the core and the lower plastic skin extend laterally up to a front side of the edge beam.
2. The bridge deck according to claim 1 , wherein the core and the bottom plastic skin butt up against said front side of the edge beam or against a filling layer that covers said front side of the edge beam.
3. The bridge deck according to claim 1 , wherein the protruding part of the top plastic skin completely covers the top side of the edge beam.
4. The bridge deck according to claim 1 , wherein an angle profile is provided at the free edge of the protruding part of the top plastic skin and the edge beam, wherein one leg of the angle profile covers a top surface of the protruding part or a cover layer located on the protruding part, and wherein a further leg of the angle profile extends along a boundary edge of the protruding part of the top plastic skin, the edge beam and any cover layer present on the protruding part.
5. The bridge deck according to claim 1 , wherein the composite panel comprises, a top plastic skin, a bottom plastic skin, and a core arranged between and attached to the plastic skins, wherein the top plastic skin has a protruding part which laterally protrudes relative to both the core and the bottom plastic skin, and wherein the protruding part of the top plastic skin includes a row of openings, configured to receive a peg or bolt.
6. The bridge deck according to claim 5 , wherein the bottom plastic skin includes a row of lower openings which extends parallel to the row of openings in the protruding part of the top plastic skin, wherein a distance between the row of openings and a edge of the core adjacent to and below the protruding part of the top plastic skin is of the same order of magnitude as a width of the protruding part.
7. The bridge deck according to claim 1 , wherein the composite panel comprises a bulkhead that delimits the core, wherein said bulkhead abuts said front side of the edge beam or a filling layer that covers said front side of the edge beam.
8. The bridge deck according to claim 7 , wherein the filling layer is an adhesive layer.
9. The bridge deck according to claim 1 , wherein the protruding part of the top plastic skin includes openings, wherein the edge beam includes further openings, each of said further openings being aligned with a respective one of said openings, and wherein a peg or bolt extends through each respective pair of aligned openings and further openings.
10. The bridge deck according to claim 9 , wherein the top side of the edge beam includes said further openings.
11. The bridge deck according to claim 10 , wherein the edge beam has a top flange that at least partly defines the top side of the edge beam, and wherein the top flange includes the further openings.
12. The bridge deck according to claim 10 , wherein a row of pairs of openings is provided which extends in the longitudinal direction of the edge beam, of which row at least one pair of openings and the associated peg cooperate closely and other pairs of openings have at least one opening in the form of a slot, the largest dimension of which is directed in the longitudinal direction of the support beam, to compensate for the expansion differences between the edge beam and the composite panel.
13. The bridge deck according to claim 1 , wherein the edge beam has a bottom flange on which the bottom plastic skin is supported.
14. The bridge deck according to claim 13 , wherein the bottom plastic skin and the bottom flange have lower openings and further lower openings, respectively, wherein each lower opening is aligned with a corresponding further lower opening, and wherein a peg extends through each pair of a lower opening in the bottom plastic skin and an further lower opening in the bottom support flange.
15. A bridge construction comprising a bridge support or abutment for supporting the bridge deck according to claim 1 , the bridge deck comprising a composite panel with a top plastic skin, a bottom plastic skin, and a core arranged between and attached to the plastic skins, and an edge beam extending along an edge of the composite panel and resting on the bridge support, wherein the top plastic skin has a protruding part which laterally protrudes relative to both the core and the bottom plastic skin, wherein the protruding part of the top plastic skin extends over and is attached to a top side of the edge beam, and wherein both the core and the lower plastic skin extend up to a front side of the edge beam.
16. An edge beam for a bridge deck according to claim 1 , with a top side and a bottom side, a front side for facing the composite panel, and a back side opposite to the front side, wherein the top side has a row of further openings extending in the longitudinal direction, each further opening being configured to receive a peg or bolt, wherein the front side is provided with a bottom flange which protrudes from the front side and in a lateral direction away from the back side, wherein said bottom flange includes a row of further lower openings is, each further lower opening being configured to receive a peg.
17. The edge beam according to claim 16 , comprising a box section that defines said front side from which the bottom flange protrudes.
18. The edge beam according to claim 16 , wherein the bottom flange is located at non-zero distances from the top side and from the bottom side, viewed in a height direction of the edge beam.
19. The edge beam according to claim 18 , wherein the top side has a top flange which protrudes from the back side and in an opposite lateral direction away from the front side, wherein said top flange includes the row of further openings.
