Title:
RAINWATER NON-STORABLE GUTTER OF USING CAPILLARY PHENOMENON
Document Type and Number:
Japanese Patent JP2019094687
Kind Code:
A
Abstract:
To prevent this by executing gravitational drainage by a capillary phenomenon and gravity in the present invention, though impairing the function and an aesthetic appearance by the occurrence of an alga and moss, by causing a water drip, since a residual rainwater quickens the deterioration of a gutter, when the rainwater remains by an angle caused by surface tension, a joint and a construction error even after rain stops.SOLUTION: A fibrous raw material for generating a capillary phenomenon by making a concave groove on a horizontal gutter upper bottom surface, is installed in a groove. Gravitational drainage is executed by a capillary phenomenon and gravity by continuously installing the same raw material even on a catchment basin internal side surface and a down-pipe internal side surface. According to this embodiment, even if there are more or less angles and irregularity of a joint, drainage to a catchment basin and a down-pipe can be executed by the capillary phenomenon. When the fibrous raw material is deteriorated, the effect can be recovered by replacing and installing.SELECTED DRAWING: Figure 1
