【考案の詳細な説明】 〔考案の目的〕 （産業上の利用分野） 本考案は、主に校舎やマンションや事務所のビルなど
の建物の屋上に降った雨水等を集めて下に排水する屋上
排水装置に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) This invention mainly collects and drains rainwater and the like that have fallen on the roof of buildings such as school buildings, condominiums, and office buildings. It relates to a rooftop drainage device.

より建物の外壁面に係止している。2. Description of the Related Art Conventionally, this type of rooftop drainage device has a lateral drainage drain buried in a roof side wall which is an outer wall of a building by a driving method or the like, and one end is connected to a connection port of the lateral drainage drain. Is buried so as to penetrate the side wall portion. Also, a box-shaped decorative box is fastened to the outer wall surface of the building so as to cover the outer protrusion of the other end of the call gutter from the outside of the building, and the upper end is connected to a lower drain port of the decorative box. The downspout pipe is hung along the outer wall of the building to the ground, and a plurality of portions of the downpipe are stopped on the outer wall of the building by metal fittings such as stop bands.

になる。The rainwater, etc., which has fallen on the rooftop, collects and flows into the drain for drainage at the side entrance, enters the decoration basin outside the building via the drainage pipe from the drain, and flows down from the drainage port at the lower end of the pit pipe directly below, and falls down the ground. Will be drained into rainwater basins and drains.

り排水機能の能力低下を招き易い問題があった。In addition, since the downspout pipe has a complete cylindrical shape that seals the peripheral wall (does not open to the atmosphere) and is disposed over a long distance from near the roof of the building to the ground, rainwater and the like that have flowed into the pipe are distributed. Due to the internal pressure of the downspout pipe, its downflow speed is slow,
In addition to the problem that the drainage capacity is low, there is a problem that even if dust or the like is clogged in the downspout pipe, the cleaning and removing operation cannot be easily performed, and the drainage capability is more likely to be reduced.

It is drained down. At this time, since the outer surface of the deep gutter is open for a long time in the vertical direction, rainwater etc. smoothly falls freely inside the hard gutter without receiving internal pressure unlike a conventional hard gutter tube having a closed peripheral wall. In addition, a high drainage function can be obtained, and the deep gutter has draining plates protruding obliquely inward in the vertical direction on both open side edges. There is no inconvenience such as falling down inside the board and scattering outside.

At the location where 21c faces, a vertically long groove 30 is formed straight from there to the lower end of the outer wall 1 of the building.
A downspout 31 is provided so as to be fitted into the inside thereof vertically. The downspout 31 is made of stainless steel with excellent corrosion resistance and good appearance like the decorative box 20. The downspout 31 has a rectangular cylindrical shape with upper and lower end portions having outer plate portions 32 and 33 within an appropriate length range, but is longer in the vertical direction on the way except for the upper and lower portions. The section extending over has a U-shape in cross section with the outer side open, and the draining plate 34 protrudes inward at approximately 45 degrees inward in the vertical direction on both sides of the open side.
Are bent integrally. The upper end of the downspout 31 is connected to the lower drain port 21c of the decorative box 20,
It is connected so as to fit between 1d and the gutter retainer 21e, and the lower end is bent out of the groove 30 and inserted into the rainwater basin 40 (or a drainage groove (not shown)) on the ground. I have. A plurality of locations in the middle of the back plate portion of the downspout 31 are fixed to the inner surface of the groove 30 by fasteners 41 such as concrete nails.
