The Concrete Reinforcing Steel Institute (CRSI) has developed standard symbols, graphics, and formats for shop drawings and cut sheets that generally are used by reinforcing steel fabricators. [5] Each fabricator, has particular style for shop drawings and cut sheets, depending on the drafts people and Computer-aided design systems.
Basic Erector parts included various metal beams with regularly spaced holes for assembly using nuts and bolts. A frequently promoted patented feature was the ability to fabricate a strong but lightweight hollow structural girder from four long flat pieces of stamped sheet steel, held together by bolts and nuts (US Patent 1,066,809).
A matchbox is a container or case for matches, made of cardboard, thin wood, or metal, generally in the form of a box with a separate drawer sliding inside the cover. Matchboxes generally measure 5 x 3.5 x 1.5 cm, and commonly have coarse striking surfaces on the edges for lighting the matches.
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes , brake presses , and other specialized machine presses .
The Office specifies the size of the sheet on which the drawing is made, the type of paper, the margins, and other details relating to the making of the drawing. The reason for specifying the standards in detail is that the drawings are printed and published in a uniform style when the patent issues and the drawings must also be such that they ...
Shearing may be permitted only in certain areas of the sheet due to limitations of the machinery (e.g. always across the whole sheet); Some cutting technologies (plasma) require some minimal offset between the parts; Nesting software may also have to take into account material characteristics, such as: Defects on material that must be discarded;
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...
A specific material may be covered in several locations, depending on the work result: stainless steel (for example) can be covered as a sheet material used in flashing and sheet Metal in division 07; it can be part of a finished product, such as a handrail, covered in division 05; or it can be a component of building hardware, covered in ...
