PURPOSE:To strongly and exactly connect structural parts with simple and cheap connecting metals by a method in which main bars and subbars are integrally connected by connecting metals consisting of a plate spring material through their claws and couplers. CONSTITUTION:A main bar 10 having an H-shaped hanger 12 on the upper end of its vertical part 11 and a U-shaped receiver 13 on its lower end, and a subbar 20 having a U-shaped coupler 21 on its central part and having a height about 1/3 of the bar 10 are used. The bars 10 are hung down in parallel from the ceiling and coupling grooves 33, 33 are joined with the couplers 24, 24 for sliding of the bar 20. The coupler 32 is inserted into the recession 21 to make up a connecting metal 30, and the claw part 31 of the metal 30 is pressed into the coupling groove 15 for elastic coupling. The ends are inserted into the coupler 16 for preventing slackening to combine the bars 20 to form a latticed framework. A ceiling plate is then placed on flanges 14 and 22. |
