Abstract:

A bridge is constructed using simply structured, longitudinal, modular deck sections or cells that are fabricated in a shop and shipped to the jobsite for quick assembly and erection. Each section has generally horizontal upper and lower members and at least one generally vertical member connected between the upper and lower horizontal members. The sections may be C-shaped, Z-shaped, or shallow U-shaped, and are connected in series. The upper and lower horizontal members of each section overlap respectively portions of the upper and lower horizontal members of the adjacent section to form overlapped regions. The connection sections define a plurality of closed cells. Open cells at the ends may be closed using appropriate end section(s) that may be shallow C-shaped or J-shaped. The sections are roll-formed or press braked from metal sheets or plates. The sections are connected together to form a multi-cell box girder bridge module by mating and welding or bolting the overlapped regions.

International Classification:

B21C 3712

US Classification:

72 49

Abstract:

A method and apparatus is described for use in combination with a machine for corrugating a continuous strip of flat sheet material which prepares the sheet material for separation into sections after it has been corrugated. A platform is located upstream of the corrugating machine. The platform is intermittently advanced in the direction of travel and at the speed of the sheet material so that the platform is stationary relative to the sheet material. A scoring device is located on the platform. The scoring device moves across the width of the sheet material as the platform moves with the sheet material to form a spanwise weak point in the material. After the material passes through the corrugating machine, it can readily be separated into sections at the weak points formed in the material by the scoring device. Depth of scoring can be varied also so that substantial/total separation can also occur within the corrugator though it would not separate the flat strip before it entered the corrugator.

Appl. No.:

5/900383

Inventors:

Eugene W. Sivachenko - Redding CA

International Classification:

E02D 500

US Classification:

405284

Abstract:

Corrugated steel plate is formed from a flat plate stock and has a length of at least about 12 feet, a corrugation pitch of at least about 12 inches, and a corrugation depth of at least four inches. The plate has thicknesses of up to 1/2 inch and more. Also disclosed are structures such as tunnel-type, heavy load-supporting structures defined by upright and horizontal structure portions which extend over no more than about 180. degree. while being capable of supporting up to 40 feet of ground fill and payload thereon. The corrugated plate can be used singly or as double, spaced-apart plate assemblies which are hollow or filled with concrete or a like material, including steel reinforcing bars for the concrete. The corrugated plate can also be formed into vertical, sectional retaining walls, bin type retaining walls, bridge abuttment walls, flat support surfaces such as bridge decking, open air structures, guard rails, sheet piling, etc.

International Classification:

US Classification:

72180

Abstract:

A machine for forming corrugated plate from a flat sheet defined by a plurality of serially arranged corrugating stands. At least one stand has cooperating corrugating rolls defined by a plurality of disc shaped dies which, during corrugating, are rotated at differing rates so that the peripheral speed at a selected diameter, of each such disc substantially equals the linear speed of the plate being corrugated. The discs can be constructed of disc shaped die halves, the axial position of which can be varied so as to vary the corrugation pitch or the profile while maintaining the pitch constant. Drives for the corrugating rolls and, in particular, for the disc dies can power rotate all dies or only some of them while others are free wheeling. Also disclosed are an advantageous construction of the frame which establishes metal-to-metal contact between bearing blocks of the roll shafts so as to rigidify the frame while permitting ready replacement of the shafts and/or the dies; the construction of the discs of ring halves; the axial mounting of the discs to their shafts and alternative drives for the discs including planetary gear drives, internal ring gear drives, and individual drives.

US Classification:

Abstract:

A corrugated plate is disclosed which has trapezoidal corrugations defined by alternating, side by side, relatively thick corrugation peaks and corrugation troughs and relatively thin, inclined corrugation sides which interconnect edges of adjoining peaks and troughs. A method is also disclosed for corrugating the corrugated plate from flat sheet by providing a flat sheet with spaced apart, longitudinally extending, relatively thick sections which thereafter define the corrugation peaks and corrugation troughs or for forming the thick sections by providing a relatively thin sheet and folding over portions of the thin sheet in the areas which ultimately form the corrugation peaks and corrugation troughs so that the latter are defined by a plurality of staked sheet layers.

Abstract:

A load carrying vehicle such as a truck trailer or a railroad car has a generally flat, horizontal loading surface which is supported by an underframe which in turn is mounted to and carried by wheel assemblies, kingpin-saddle plate arrangement and the like. The underframe extends over the full length and width of the load carrying vehicle and each of its transverse cross-sections is of a substantially constant height while in a longitudinal direction the center portion of the underframe is of a relatively greater height than portions of the underframe adjacent the wheel assemblies. The underframe is constructed of a first corrugated plate in which the corrugations run longitudinal of the vehicle. A second corrugated plate is secured to the underside of the first mentioned plate and the plates are arranged so that the corrugation troughs of the upper plate are in longitudinal alignment with corrugation peaks of the lower plate to define a hollow core honeycomb pattern between the plates. Mutual contact points between the plates, e. g.
