Abstract
High-rise reinforced concrete buildings have increased, and in these construction sites we have used the method of prefabricated deformed bars. We thought pressure welding was not suit in the method of prefabricated deformed bars, but performance of pressure welding machine has improved. Recently we can use pressure welding in the method of prefabricated deformed bars. Several cases of pressure welding in the method of prefabricated deformed bars and demonstrated test of general column and beam are presented in this paper.
