Self assembly drainage facility for apartment building balcony

摘要

The present invention relates to a prefabricated drainage facility for a balcony of a multi-family house, and more specifically, it is seated on the bottom surface of a balcony in the form of a square box with an internal storage space, an opening in the lower surface is formed in the center of the lower surface, and a border of the lower opening An extension tube extending downwardly and inserted downwardly to a certain depth inside the drain hole formed in the balcony is integrally formed, an upper surface opening is formed in the center of the upper surface, a cover covering the upper surface opening is provided, and water on the balcony floor is provided on the outer surface. A water collecting body having an inflow hole through which the water is introduced and collected into the receiving space, and water that is collected at a certain height or higher from the inside of the water collecting body through the outer surface of the water collecting body is inserted into the water collecting body. The inlet is formed at one end, and the other end is connected to the outer surface of the drain trap, so that the water flowing into the inlet is discharged. A hollow bypass passage having a discharge port discharged into the trap and a bottom part of the balcony, and a first drain pipe through which the water collected by the water collecting box is drained by being inserted upward to the inside of the balcony drain port and the bypass passage A drain trap having a second drain pipe through which water transported through is drained, and a third drain pipe in communication with the drain pipe so that water drained through the first drain pipe and the second drain pipe is drained through the drain pipe of the apartment house. Included, the vertical central axis of the first drain pipe and the vertical central axis of the third drain pipe relates to a prefabricated drainage facility for a balcony of a multi-family house characterized in that they do not match each other. According to the present invention, it is possible to temporarily store the water collected on the balcony to relieve the load of the drain trap and to drain the balcony water by bypassing it even if clogging of the drain trap occurs.
