CONNECTION STRUCTURE OF SQUARE TUBULAR STEEL COLUMN TO WIDE FLANGE BEAM

摘要

PROBLEM TO BE SOLVED: To provide a joining of a rectangular steel tubular column with a wide flange beam of excellent strength and easy execution by joining auxiliary plates with a side of the rectangular steel tubular column in advance, and joining the auxiliary plates with a flange of the wide flange beam by an angle using bolts. ;SOLUTION: Four auxiliary plates 21 are welded to a side part of a rectangular steel tubular column 1. Extension parts of the auxiliary plates 21 are joined with a flange 5a of a wide flange beam 5 by an angle-shaped piece 23 using bolts. The auxiliary plates 21 are worked in a lattice manner, inserted into the rectangular steel tubular column 1, and welded in advance in a factory. A frame is reinforced by the angle-shaped pieces 23 which are arranged inside of the auxiliary plates 21 using a box-shaped connection member and a channel- shaped connection member. Defective execution is reduced in number, the working period is reduced, and the cost is reduced by welding the auxiliary plates 21 in the factory, and performing only the bolt joining at site.;COPYRIGHT: (C)1997,JPO
