Columns for multistory building framework, have steel profiles each comprising tube and steel overhangs supporting ends of beams, where tube is connected to pressurized water supply through valve system

摘要

The columns have steel profiles each comprising a tube (6) and steel overhangs (7) supporting ends of beams. The overhangs are disposed at right angle with respect to each other and are radially fixed against exterior of the tube. Each of the overhangs carries two wings (8) at an edge opposite to the tube, where the wings are perpendicular to the overhang. The tube is connected to a pressurized water supply through a valve system. An independent claim is also included for a multistory building framework.
