BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical drain.

[0002]

2. Description of the Related Art Drains for draining rainwater are used on the roofs of buildings such as buildings and condominiums and on the verandas on each floor, and drains of this type are used as rainwater. Is a vertical drain in which is introduced from above and discharged downward.

FIG. 3 shows an example of a conventional vertically drawn drain, in which 1 shows a drain body inserted and installed in a drain port 3 provided on a floor 2.
It is designed to be fitted to the upper end of a drain pipe 4 disposed vertically below a drain port 3 provided on the floor 2, and to be installed above the drain main body 1 on the upper side of the drain main body 1. The drain cover 5 is attached from the viewpoints of preventing intrusion of solid matter such as water and twigs, avoiding the danger of the drain port 3 being exposed, maintaining aesthetic appearance, and the like.

The drain main body 1 has a flange 6 formed on the outer periphery of the upper end thereof. A fixing tool (not shown) is provided with a fixing bolt 7 whose upper end is screwed to an inner portion of the lower surface of the flange 6 and extends downward. And is fixed to an appropriate structural part of the floor 2 via the base.

Further, the flange portion 6 of the drain main body 1 is provided.
A waterproof sheet 8 is laid from the upper surface of the floor 2 to the entire upper surface of the floor 2.
Is flattened between the flange portion 6 and a flat ring type sheet press fitting 10 which is concentrically mounted on a portion closer to the inner side via a plurality of screws 9.

The drain cover 5 is formed in a convex shape which opens up a plurality of water intake ports 11 and bulges upward, and a flange 12 formed on the outer periphery of the lower end thereof is formed on the upper surface of the sheet holding member 10. Is mounted via a plurality of screws 13.

Further, the flange portion 6 of the drain main body 1
A plurality of protrusions 14 are radially arranged on the inner side, and each of the protrusions 14 is provided at a plurality of circumferentially open water inlets 11 on the lower portion of the drain cover 5.
The projections 14 can keep the falling into the drain pipe 4 even if the solids enter through the water inlets 11.

[0008]

However, in the above-described conventional vertically drawn drain, solids that have slipped through the water intake 11 of the drain cover 5 and entered inside are retained by the projections 14 of the drain body 1. In addition, the settled sludge gradually accumulates on the retained solids, so it is necessary to periodically clean the inside. The screw 13 must be loosened, the drain cover 5 must be removed, and after cleaning, the screw 13 must be tightened again and the drain cover 5 must be reattached.
During the work of removing the screws, there has frequently been a problem that the screws 13 are dropped into the drain pipe 4 and are lost.

Further, since the drain cover 5 must be removed for the cleaning operation, a dedicated sheet holding fitting 10 is required so that the waterproof sheet 8 can be held down even when the drain cover 5 is removed. Thus, there is also a problem that the work process is increased by the amount of attaching the sheet holding member 10 to the drain main body 1 via the plurality of screws 9 at the time of construction, and it is troublesome.

Further, since a plurality of protrusions 14 are provided on the inner side of the flange 6 of the drain body 1, the contact area of the flange 6 with the waterproof sheet 8 becomes relatively small, and There was also a problem that it was difficult to ensure the sealing performance of the device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a vertically drawn drain capable of cleaning the inside without removing the drain cover, so that the inside can be easily cleaned. In addition, the object of the present invention is to eliminate the need for sheet holding fittings, save labor during construction, and to further improve the sealing performance of the waterproof sheet.
