Girder system employing bent steel plating
First Claim
1. A load-carrying girder presenting a longitudinal span for supporting an overlying superstructure, comprising:
- an upper flange section defining a bearing surface, the upper flange section having a longitudinally extending ridge;
a set of upper continuous transitional bends formed on opposed lateral sides of the upper flange;
a set of web sections spaced apart from one another, each web section extending downwardly from one of the transitional bends; and
a base section formed below and extending from the set of web sections, the base section including individual flanged footings projecting generally laterally towards one another;
wherein the ridge of the upper flange is formed with a set of laterally extending, spaced apart apertures formed therethrough, the apertures being configured to receive a reinforcing member.

Abstract
A structural support system employs a modified inverted box girder design for improved performance and ease of fabrication. Each girder of a series of girders is formed with an upper flange section, a set of web sections extending from opposite lateral sides of the upper flange section, and a base section below the web sections. The base section includes individual flanged footings that project generally towards one another. The particular cross-sectional configuration of each girder may be formed by bending a continuous steel plate along at least a first set of preselected parallel lines to establish a set of upper continuous transitional bends with the upper flange section therebetween, as well as a remainder portion forming at least the set of web sections. A deck is coupled with the series of girders to form the structural support system.

6. A structural support system comprising:
-
one or more longitudinally oriented girders, each girder having an upper flange section defining a bearing surface, a set of web sections extending downwardly from transitional bends formed on opposed lateral sides of the upper flange section, and a base section formed below the set of web sections, the base section including individual flanged footings projecting generally laterally towards one another; and a deck coupled to the one or more girders through the upper flange section, the deck having a bottom surface overlying the bearing surface of the series of girders; wherein the upper flange section of each girder is formed with a longitudinally extending ridge having a set of spaced apart apertures through which the deck couples with the series of girders. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for fabricating a load-carrying element of a structural support system, comprising:
-
bending a series of continuous steel plates along a plurality of preselected longitudinal lines to form a series of load-carrying girders, each girder having an upper flange section defining a bearing surface, a set of web sections extending downwardly from transitional bends formed on opposed lateral sides of the upper flange section, and a base section formed below the set of web sections, the base section including individual flanged footings; forming a concrete slab deck encasing a grid of reinforcing members; and coupling the deck to each girder of the series of girders such that the series of girders extend in a parallel arrangement with respect to one another; and wherein coupling the deck to each girder includes extending at least some of the reinforcing members through a raised feature of the upper flange section of each girder. - View Dependent Claims (14, 15)
