JOINING STRUCTURE OF CONCRETE FILLED STEEL PIPE COLUMN-BEAM

摘要

PURPOSE: Provided is a joint structure of angular steel-pipe girder for column charged with concrete to eliminate interference of crossed bolts when the girders at four sides of the column are connected at the same time by means of U shaped bolt in a bolt welding mode for the column and the girder. CONSTITUTION: The structure is for jointing H beams(30,31) at both ends of an angular steel pipe and comprises end plates(41,42) integrated and connected at each end of the H beams(30,31). The end plates(41,42) are contacted to face each other at outer connection side of the steel pipe(20) and connected to the pipe(20) by means of U shaped bolt(50) as a coupling device. Concrete material is introduced into a closed side of the steel pipe and integrated with a portion of the bolt(50) to lead both of the H beams(30,31) and the steel pipe(20) to be jointed.
