Fitting for effecting bolted connection between a beam and a column in a steel frame structure

Method of constructing a steel frame structure, comprising:

• providing a first bracket having a beam connecting plate and a column connecting element extending from the beam connecting plate, said column connecting element having an outer surface and being provided with a plurality of through holes;
• providing a second bracket having a beam connecting plate and a column connecting element extending from the beam connecting plate, said column connecting element of said second bracket having an outer surface and being provided with a plurality of through holes;
• forming a plurality of first holes in a flange of a column;
• forming a plurality of second holes in the flange of the column;
• connecting said beam connecting plate of said first bracket to a first flange of a beam and connecting said beam connecting plate of said second bracket to a second flange of the beam;
• placing said beam so that an end of the beam is in contact with an outwardly facing surface of the flange of the column and so that the outer surface of the column connecting element of said first bracket and the outer surface of said column connecting element of the second bracket each face the outwardly facing surface of the flange of the column;
• and
• connecting the column connecting element of said first bracket and said column connecting element of said second bracket to the flange of the column by providing a plurality of a bolted connections each extending through one of the holes in the column connecting element of said first bracket and one of the first holes in the flange of the column and a plurality of second bolted connections each extending through one of the holes in the column connecting element of said second bracket and one of the second holes in the flange of the column.

Fitting for connecting together a beam and a column in a steel structure, comprising a one piece L-shaped bracket that includes a horizontal beam connecting element for being connected to a beam forming a part of a steel structure, and a vertical column connecting element for being connected to a column forming a part of the steel structure, said column connecting element lying in a vertical plane, said column connecting element and said beam connecting element intersecting to define an inner corner of the bracket, said horizontal beam connecting element having an outer surface adapted to face a flange of the beam and said vertical column connecting element having an outer surface adapted to face a flange of the column, said L-shaped bracket having an outer corner edge adapted to be positioned at a corner formed between the beam and the column, said horizontal beam connecting element lying in a horizontal plane and said bracket being asymmetrical about said plane, said horizontal beam connecting element having a free end opposite from said outer corner edge, the entirety of said free end of said horizontal beam connecting element lying in said horizontal plane, said column connecting element having a plurality of through holes formed in two rows for alignment with holes in the column to provide a bolted connection between the column connecting element and the flange of the column, said column connecting element having a free end opposite from said outer corner edge, the entirety of said free end of said column connecting element lying in said vertical plane, a reinforcing element extending between the column connecting element and the beam connecting element, said reinforcing element being positioned between the two rows of holes in the column connecting element, said reinforcing element extending along the column connecting element from the inner corner to substantially the upper free end of the column connecting element, said reinforcing element extending along the beam connecting element from the inner corner to substantially a free end of the beam connecting element.
