PURPOSE:To make it possible to quickly connect the end of a channel to a plate-like section with a self-tapping screw without using a clamp, etc., and to promote durability against compressive force lengthwise of the channel by contacting the front end of a web with the plate-like section. CONSTITUTION:Slits 16 and 16 having the approximately same thickness as that of a plate-like section 26 of a lower intertruss bracing receiver 20 are formed in approximately parallel with a plane of a web 12 in the roots of a pair of flanges 14 and 14 in the ends of a channel 10 using as a brace for intertruss bracing. The plate-like section 26 is fitted to the slits 16 and 16, at the same time, both sections of the web 12 of the ends of the channel 10 and the plate-like section 26 are overlapped each other, and a self-tapping screw 30 is secrewed to the channel 10. The web 12 is placed to an interior angle side of the plate-like sections 24 and 26 at right angles. |
