Abstract
A ribbed metal plate for a composite slab that includes a substantially planar plate having an upper surface and a lower surface and a plurality of laterally-spaced, longitudinally-extending ribs that have a keystone profile and wherein the sidewalls are angled toward each other. Ends of the ribs are integrally formed. The rib plate is secured to bearing walls in a structure and concrete is poured on the ribs to form a composite deck. The ends of the ribs extend in the lateral direction to form a composite structure retarding movement of cured concrete in a longitudinal direction. The ribbed plate can also be used in composite beams.

A ribbed plate for a composite deck, comprising:
- a substantially planar plate having an upper surface and a lower surface;
- and
- a plurality of laterally-spaced, longitudinally-extending protruding ribs, each of said ribs includes spaced apart sidewalls connected to a top wall, said sidewalls angled toward each other and defining a rib profile, said laterally-spaced, longitudinally-extending ribs extending from a first end of said planar plate to a second end of said planar plate, each of said longitudinally-extending ribs having a first end and a second end that are closed thereby defining a hollow rib chamber, said rib-closed first end and said rib-closed second end extend along a lateral direction outwardly from and relative to the respective rib profile, a recessed concrete receiving area is defined by one of said rib sidewalls, an adjacent portion of said planar plate, and respective portions of said rib-closed first end and said rib-closed second end, whereby when said upper surface of said planar plate is embedded in concrete, the concrete is prevented from flowing into the hollow rib chamber through said closed rib first end and said closed rib second end.
A composite deck comprising:
- a ribbed substantially planar plate having an upper surface and a lower surface, and a plurality of laterally-spaced, longitudinally-extending protruding ribs, each of said ribs includes spaced apart sidewalls connected to a top wall, said sidewalls angled toward each other and defining a rib profile, said laterally-spaced, longitudinally-extending ribs extending from a first end of said planar plate to a second end of said planar plate, each of said longitudinally-extending ribs having a first end and a second end that are closed thereby defining a hollow rib chamber, said rib-closed first end and said rib-closed second end extend along a lateral direction outwardly from and relative to the respective rib profile, a recessed concrete receiving area is defined by one of said rib sidewalls, an adjacent portion of said planar plate, and respective portions of said rib-closed first end and said rib-closed second end, whereby when said upper surface of said planar plate is embedded in concrete the concrete is prevented from flow into the hollow rib chamber through said closed rib first end and said closed rib second end;
- and
- a concrete layer positioned on said upper surface of said ribbed plate, whereby concrete surrounds said ribs and said ribs are embedded in said concrete.
A structure comprising at least two longitudinally-spaced support members and a composite deck attached to said support members, wherein the composite deck comprises:
- a ribbed substantially planar plate having an upper surface and a lower surface, and a plurality of laterally-spaced, longitudinally-extending protruding ribs, each of said ribs includes spaced apart sidewalls connected to a top wall, said sidewalls angled toward each other and defining a rib profile, said laterally-spaced, longitudinally-extending ribs extending from a first end of said planar plate to a second end of said planar plate, each of said longitudinally-extending ribs having a first end and a second end that are closed thereby defining a hollow rib chamber, said rib-closed first end and said rib-closed second end extend along a lateral direction outwardly from and relative to the respective rib profile, a recessed concrete receiving area is defined by one of said rib sidewalls, an adjacent portion of said planar plate, and respective portions of said rib-closed first end and said rib-closed second end, whereby when said upper surface of said planar plate is embedded in concrete the concrete is prevented from flow into the hollow rib chamber through said closed rib first end and said closed rib second end;
- and
- a concrete layer positioned on said upper surface of said ribbed plate, whereby concrete surrounds said ribs and said ribs are embedded in said concrete, wherein said rib sidewalls retard movement of said concrete layer in a lateral direction and a vertical direction and portions of said first end and portions of said second end of each of said ribs retard movement of said concrete layer in a longitudinal direction.
A method for forming a ribbed plate for a composite deck comprising the steps of:
- a) forming a plurality of laterally-spaced, longitudinally-extending ribs in a deformable metal member, wherein each of the ribs has a top wall connected to two converging sidewalls, a first end and a longitudinally-spaced second end;
- and
- b) crushing each of the rib ends so that the rib ends extend in a lateral direction and are closed.
A composite deck beam comprising
- at least two ribbed substantially planar plates, wherein each of said planar plates includes a ribbed substantially planar plate having an upper surface and a lower surface, and a plurality of laterally-spaced, longitudinally-extending protruding ribs, each of said ribs includes spaced apart sidewalls connected to a top wall, said sidewalls angled toward each other and defining a rib profile, said laterally-spaced, longitudinally-extending ribs extending from a first end of said planar plate to a second end of said planar plate, each of said longitudinally-extending ribs having a first end and a second end that are closed thereby defining a hollow rib chamber, said rib-closed first end and said rib-closed second end extend along a lateral direction outwardly from and relative to the respective rib profile, a recessed concrete receiving area is defined by one of said rib sidewalls, an adjacent portion of said planar plate, and respective portions of said rib-closed first end and said rib-closed second end, whereby when said upper surface of said planar plate is embedded in concrete the concrete is prevented from flow into the hollow rib chamber through said closed rib first end and said closed rib second end;
- and
- a continuous concrete layer positioned on said upper surface of said ribbed plates, whereby concrete surrounds said ribs and said ribs are embedded in said concrete, and wherein a concrete beam is spaced between said two longitudinally-spaced planar plates, and wherein said two planar plates are longitudinally-spaced by said concrete beam, said concrete beam being integral with said continuous concrete layer.
