Description

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

Traditionally, rain gutters in residential buildings generally consist of eaves gutters that receive rainwater falling from the roof, and vertical gutters that are connected to the eaves gutters via water collectors and feeder gutters, but in recent years, from a design perspective, , narrow downpipes are often used. However, if the gutter is narrow, the water may not be able to drain completely during heavy rain and may overflow. To this end, a vertical gutter joint has been proposed that utilizes the siphon principle to increase the amount of water discharged per unit time, allowing even narrow rain gutters to appropriately drain rainwater during heavy rains (Patent Document 1). ).

Japanese Patent Application Publication No. 2012-144870

In Patent Document 1, an overhanging member that can elastically deform and widen the opening inside the vertical gutter joint according to the amount of flowing rainwater uses the siphon principle as a high drainage type vertical gutter joint. It is characterized by being installed inside the gutter joint. When constructing a rain gutter, it is possible to confirm whether it is a high-drainage type gutter joint by checking the inside of the gutter joint, but after construction, it cannot be identified from the outside of the gutter joint. If a problem occurs after construction and it is necessary to confirm whether the component is a high-drainage type component, the work efficiency is poor because it is necessary to disassemble the rain gutter and check the inside of the vertical gutter joint.

The present invention was made in view of these problems, and it is an object of the present invention to identify whether a vertical gutter joint is a high drainage type vertical gutter joint or not, using the siphon principle, without disassembling the gutter even after the gutter is installed. We provide vertical gutter joints and rain gutter structures that make it possible.

A vertical gutter joint according to one aspect of the present invention is a vertical gutter joint used for a vertical gutter that guides rainwater from an eaves gutter to a drainage outlet on the ground. The gutter joint is a cylindrical body with both ends open, and has connecting portions at both ends that are fitted and bonded to the gutter, respectively. The gutter joint has a protrusion that protrudes inward from the inner wall surface of the cylindrical body. The gutter joint is a high drainage type gutter joint having a second opening in which the internal cross-sectional area of the cylinder is reduced by the overhang. The gutter joint is characterized in that it is equipped with a high drainage gutter joint identification mechanism that can confirm whether or not the gutter joint is a high drainage type member.

A rain gutter structure according to one aspect of the present invention is characterized in that the down gutter is connected by the down gutter joint provided with a high drainage down gutter joint identification mechanism.

The effect of the present invention is that by providing a high drainage down gutter joint identification mechanism on the down gutter joint, when some kind of problem occurs after construction of the rain gutter and it is necessary to check whether the down gutter joint is a high drainage type member, It becomes possible to identify whether a vertical gutter joint is of a high drainage type or not without disassembling the gutter, improving work efficiency.

In addition, as shown in FIG. 3, the vertical gutter joint 200 has an overhanging portion 203 that overhangs inward from the inner wall surface 202 of the cylindrical body and is formed in the circumferential direction. A second opening S2 is formed that has a reduced internal cross-sectional area of the overhang 203 compared to the first opening S1 that has an internal cross-sectional area of the projecting portion 202 . As a result, the flow of rainwater is obstructed and the area above the overhang 203 becomes full of water, causing a siphon phenomenon, so rainwater is drained away from the vertical gutter joint 200 with great force, greatly improving wastewater treatment capacity. Therefore, the downpipe joint 200 is provided with a high drainage function.

In this way, by providing the overhanging portion 203 on the inner side of the vertical gutter joint 200, it is possible to provide a high drainage function.
