摘要

PROBLEM TO BE SOLVED: To easily construct a gutter between external walls of a building, etc., with sufficient watertightness, and to easily take countermeasures when the building height is changed. ;SOLUTION: External wall units with external wall materials connected and attached thereto in the vertical direction are connected to each other in the vertical direction, and continuously arranged in the right-to-left direction with a small clearance therebetween. A gutter body 43 of substantially U-shaped section which is substantially as high as the external wall units in the vertical direction and opened forward is arranged on a back part across the clearance in a watertight-abutting manner on the right and left external wall units. A vertical clearance for connection is formed between the upper and lower gutter bodies 43. A small diameter gutter part 51a of a connection gutter body 51 having a small diameter gutter part 51a to be inserted in the lower gutter body 43 and a large diameter gutter part 51b to be housed over the upper gutter body 43 is inserted in the lower gutter body 43, and the large diameter gutter part 51b is housed over the upper gutter body 43.;COPYRIGHT: (C)2001,JPO
