JUNCTION STRUCTURE FOR RAIN GUTTER

PROBLEM TO BE SOLVED: To prevent a long gooseneck from being deformed and drooped at a junction when it is executed by inserting the end section of the drain tube of an eaves gutter into an elbow, pinching it with the upper and lower pressing plates, coupling a coupling lug with a coupling hole, and fixing the pressing plates with screws. SOLUTION: A metal thin sheet is press-molded and seam-jointed and fixed by an adhesive seal material to form the drain tube A of an eaves gutter and an elbow C. An angular tube- like connection end section 1 to be inserted into the elbow C is provided nearly horizontally on the downstream side of the drain tube A, and insertion holes 12 are bored at two positions on the upper base end section of the connection end section 1. Two notches 5 and a coupling lug 51 are provided on the opening upper face on the upstream side of the elbow C, and a junction 52 is provided on the downstream side. The connection end section 1 of the drain tube A is inserted into the elbow C, a coupling section is pinched by the upper and lower pressing plates made of a band-like copper sheet, the coupling lug 51 is coupled with the coupling hole 22 of the upper pressing plate 2, a lateral drift is prevented by side plates 25, and screws 26 are inserted and fixed in insertion holes 23, 12, notches 5, and screw holes 31. Since a connection portion is firmly fixed by the upper and lower pressing plates 2, 3, the connection end section 1 is prevented from being released or drooped by weight.
