Abstract
Abstract A light-weight, corrosion-resistant, readily installed bridge deck is formed of modular deck panels spliced to each other on site. Each of the deck panels is shop-fabricated by longitudinally welding flanges of adjacently placed multi-void extruded aluminum alloy structural elements. Transfer splices of longitudinally adjacent elongate elements are made by providing shear elements connecting individual elongate structural elements of each deck panel end-to-end prior to longitudinal welding of adjacent elongate elements, with the end joints between the elongate elements being arrayed in a staggered manner. A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A modular bridge deck system supported on a plurality of cooperating girders, comprising: a plurality of prefabricated deck panels which are longitudinally field-spliced together, each deck panel being formed by longitudinally shop-welding a plurality of elongate, multi-void, extruded aluminum elements which are transversely end-spliced in a staggered arrangement; and a plurality of field-bolted mutually engaging extrusions enabling said longitudinal field-splicing of adjacent panels to each other, wherein said longitudinal shop-welding comprises one-side, full-penetration, longitudinal top and bottom welds between respective top and bottom flanges of adjoining elongate extruded aluminum elements, whereby the welded top flanges of said field-spliced panels provide a substantially continuous upper surface.
Claim 2
Dependent Claim
105 words
A modular bridge deck system supported on a plurality of cooperating girders, comprising: a plurality of prefabricated deck panels which are longitudinally field-spliced together, each deck panel being formed by longitudinally shop-welding a plurality of elongate, multi-void, extruded aluminum elements which are transversely end-spliced in a staggered arrangement; and a plurality of field-bolted mutually engaging extrusions enabling said longitudinal field-splicing of adjacent panels to each other, wherein said longitudinal shop-welding comprises one-side, full-penetration, longitudinal top and bottom welds between respective top and bottom flanges of adjoining elongate extruded aluminum elements, whereby the welded top flanges of said field-spliced panels provide a substantially continuous upper surface.
Claim 3
Dependent Claim
20 words
The bridge deck system according to claim 1, further comprising: a wearing layer applied over said substantially continuous upper surface.
Claim 4
Dependent Claim
16 words
The bridge deck system according to claim 2, wherein: said wearing layer comprises an epoxy material.
Claim 5
Dependent Claim
24 words
The bridge deck system according to claim 1, further comprising: a curb provided to extend along a longitudinal side of said field-spliced deck panels.
Claim 6
Dependent Claim
31 words
The bridge deck system according to claim 1, further comprising: a safety rail structure provided to extend along a longitudinal side of said field-spliced deck panels without making direct contact therewith.
Claim 7
Dependent Claim
42 words
The bridge deck system according to claim 4, further comprising: a safety rail structure provided to extend along a longitudinal side of said field-spliced deck panels without making direct contact therewith, wherein the safety rail structure is supported separately from the curb.
Claim 8
Dependent Claim
20 words
The bridge deck system according to claim 6, further comprising: a wearing layer applied over said substantially continuous upper surface.
Claim 9
Dependent Claim
37 words
The bridge deck system according to claim 1, further comprising: means for positively connecting the deck panels to a support system comprising cooperating girders in a manner enabling the deck panels to act compositely with the girders.
