Publication number: 20030024174Abstract: A building frame resistant to earthquakes, gale-force wind loads, fire, insects and rot includes a peripheral frame wall constructed of rectangular steel tubing. Side wall frame modules bolted together along adjacent edges, and end wall modules bolted together along adjacent edges and to the ends of the connected side wall modules form the peripheral frame wall. Diagonal bracing is built into selected side and end wall modules as required for the desired degree of wind resistance. Trusses made of various size tube such as 2×3 inch rectangular steel tubing for supporting a roof, including a hip roof, on the peripheral wall, are assembled and welded in a welding shop and the prefabricated trusses and wall modules are trucked to the building site. Multiple stories may be erected and fastened together by anchor brackets arranged bottom-to-bottom above and below the second and higher floors. The building frame is secured to a foundation by attaching the anchor brackets to anchor bolts set in the foundation.Type: ApplicationFiled: October 7, 2002Publication date: February 6, 2003Applicant: Inter-Steel Structures, Inc.Inventors: Delton J. Bonds, Eric P. Bramwell

Patent number: 6415577Abstract: A structural beam for use in the construction industry is described. The structural beam is comprised of a hollow top section and a hollow bottom section which are connected by one or two webs that may be corrugated. The hollow top and bottom sections may be rectangular. A corrugated web is also described having a trapezoidal shape. Also described is the combination of utilizing rectangular horizontal sections with a corrugated web to produce a structural beam that is light in weight, yet strong and fatigue resistant. Also described is a method of producing a structural beam having a corrugated web, a hollow top section, and a hollow bottom section.Type: GrantFiled: September 29, 2000Date of Patent: July 9, 2002Assignee: EagleSpan Steel Structures, Inc.Inventor: Jerry W.

Patent number: 6003280Abstract: A building frame resistant to earthquakes, wind loads, fire, insects and rot includes a peripheral frame wall made of side wall frame modules bolted together along adjacent edges, and end wall modules bolted together along adjacent edges and to the ends of the connected side wall modules. The side wall frame modules are constructed of rectangular steel tubing jig welded together off site at precisely 90.degree. angles so that the assembled building frame is square and true. Diagonal bracing is built into selected side and end wall modules as required for the desired degree of wind resistance. Trusses for supporting a roof on the peripheral wall, also made of rectangular steel tubing, are assembled and welded, and the trusses and wall modules are trucked to the building site.Type: GrantFiled: November 19, 1997Date of Patent: December 21, 1999Assignee: Inter-Steel Structures, Inc.Inventor: Orie Wells

Patent number: 4045995Abstract: A fluid-mechanical drive for a press brake incudes two lever members, pivotally connected between their opposite ends to two corresponding end frame members of the press brake. A pair of hydraulic cylinders pivotally connect one end of each lever member to the upper blade at spaced positions,. The opposite end of each lever member is mechanically connected to the upper blade so that upon simultaneous extension of the two fluid cylinders, a direct downward force is applied to the upper blade at two spaced positions along the blade by such cylinders and a downward reaction force is applied through the lever members and mechanical means to the upper blade at two other spaced positions along the blade to drive such blade downwardly through its working stroke into coaction with a lower blade. In one embodiment, the mechanical means are link members, each pivoted at one end to the upper blade and at the other end to a lever member.Type: GrantFiled: October 29, 1975Date of Patent: September 6, 1977Assignee: Steel Structures, Inc.Inventor: Charles H. Sparks

Patent number: 3996778Abstract: A loader and unloader for a plate roll machine has an extensible boom extending generally horizontally over the plate rolls of the machine from a stationary support frame to which the boom is pivoted at one end for vertical movement over the rolls. The boom telescopes through the action of a hydraulic cylinder from a retracted position in which the free end of the boom overlies the plate rolls to an extended position in which such free end extends outwardly beyond the plate rolls. Additional fluid cylinders pivot the boom vertically. A plate support carriage is pivoted to the free end of the boom for fore-and-aft tilting movement. The carriage has one or more rollers extending lengthwise of the boom for engaging and supporting a rolled plate at its upper inside surface. The boom is retracted and positioned vertically for supporting the plate as it is rolled in the plate rolls.Type: GrantFiled: December 8, 1975Date of Patent: December 14, 1976Assignee: Steel Structures, Inc.Inventor: Charles H.
