Description

The present invention relates to a gutter joint and a gutter structure used for connecting a gutter.

Conventionally, rain gutters in houses are generally composed of eaves gutters that receive rainwater flowing down from the roof and gutters that are connected to the eaves gutters via water collectors and gutters. , A thin gutter is often used. However, if the gutter is thin, it may not be able to drain completely and overflow during heavy rain. For this reason, a vertical gutter joint has been proposed in which the amount of drainage per unit time is increased by utilizing the principle of siphon so that rainwater during heavy rain can be drained appropriately even with a thin rain gutter (Patent Document 1). ).
