Method for forming vehicle body member
A forming method for a vehicle body member may include a tube making process of forming a steel pipe by welding a steel plate coil; a non-circular tube making process of primary preforming the steel pipe formed in the tube making process so as to have a cross section of a predetermined shape; a bending process of bending and secondarily preforming the steel pipe preformed firstly in the non-circular tube making process; and a hot stamping process of heating the secondarily preformed steel pipe, inserting the heated steel pipe into a mold to form a desired shape, and then, quenching the heated steel pipe to form a vehicle body member, thereby easily forming a vehicle body member having high rigidity.

FABRICATION LAYOUT DEVICE & METHOD
Techniques and devices are disclosed for fabrication layout device. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces are positioned on the pattern so that they can be assembled to one another.

MANUFACTURING APPARATUS AND MANUFACTURING METHOD FOR HAT-SHAPED CROSS-SECTION COMPONENT
A manufacturing apparatus for a hat-shaped cross-section component includes a die having first molding surfaces, a pad having a second molding surface, a punch having a third molding surface, a holder having fourth molding surfaces, and a first restraint portion. An upright wall is molded between a top and each of flanges by moving the pad and the punch relative to the die and the holder, or moving the die and the holder relative to the pad and the punch. The first restraint portion is configured to, during a period from when a top forming part is sandwiched by the second molding surface and the third molding surface to when the upright walls are molded, suppress displacement of the top forming part in a longitudinal direction of the top forming part relative to the second molding surface and the third molding surface.
Frame systems for building structures
A frame system for a building structure includes beam members. Each beam member includes two opposed, parallel flanges. A web is interposed between the flanges. Spreader members include two opposed, parallel side flanges, a web interposed between the side flanges and two opposed end flanges bridging the side flanges at respective terminal ends of the web. The beam members and the spreader members are configured to be fastened to each other to form a frame assembly.
