[Conventional technology]

Conventionally, the downspouts described above have been made of a single pipe with a round or square cross section, and a chain has been suspended to serve as a downspout.

[Problem to be solved by the invention]

However, downspouts using round or square pipes are easily clogged with foreign matter, such as dead leaves, and are difficult to remove. There was a problem that the appearance was damaged, and the chain swayed in the wind, making it unsuitable for use in large amounts of drainage.

This invention solves the above-mentioned problems, makes it difficult to get clogged with foreign matter, makes it easy to remove the clogged foreign matter, does not shake even when exposed to wind, has a good appearance even when draining a large amount of water, and has a design. The purpose of the present invention is to provide a downspout for roofs with a large degree of freedom.

[Means to solve the problem]

The downspout for a roof according to the present invention includes a number of front and rear horizontal plates forming an inclined part between an upper part for opening and a lower part for mounting, and a left side plate arranged at intervals from each other.
The lower ends of the front and rear horizontal boards are supported and fixed to the front and rear of the left and right pillar members, respectively.
The front and rear horizontal boards are arranged horizontally in multiple stages in the longitudinal direction of the left and right columns, with the front and rear horizontal boards facing each other, and the lower part of the upper horizontal board and the upper part of the horizontal board adjacent to the lower part are arranged vertically close to each other or They are superimposed.

[Effect]

The downspout for roofs according to the present invention uses front and rear horizontal plates that are horizontal in the longitudinal direction of the eaves gutter, and is used almost parallel to the eaves gutter. By making the right column material have different front and rear dimensions and changing the length of the front and rear side panels, water from the eaves gutter will catch water smoothly without overflowing or accumulating. In this case, by appropriately combining the dimensions of the pillars and horizontal plates, the cross-sectional area of the part where water flows can be increased to allow for a large amount of drainage. However, it is possible to maintain a good appearance. In addition, the downspout of the present invention has a structure in which the entire length of the horizontal board or both ends of the horizontal board where the horizontal board is fixed to the pillar material is provided between the lower part of the upper horizontal board and the upper part of the horizontal board adjacent below. There are gaps between the left and right sides, so you can easily remove the foreign objects by inserting a stick or other object into these gaps and pushing out the clogged foreign objects, such as dead leaves, downward, or by pulling the foreign objects out of the gaps. The combination of pillar materials and numerous horizontal plates provides great rigidity, so it does not sway even when exposed to wind.

The front and rear horizontal plates 1 and 2 are arranged vertically along the longitudinal direction of the gutter 9 so as to be substantially parallel to each other, and the upper end of the downpipe 6 has a gutter (not shown) below the end of the eaves gutter 9. The downspout 6 is held by gripping hardware (not shown) on the building 7 at multiple locations above and below at required intervals. Then, rainwater etc. from the receiving gutter 9 flows to the left side of the downspout 6 through the drainage hole and funnel provided therein.
The water is guided into the interior surrounded by the right column members 3 and 4 and the front and rear horizontal plates 1 and 2, and flows down through this interior from the lower end of the downspout 6 to an underground groove or water collection basin 10. be discharged. Further, as shown in FIG. 5, the lower end of a nominal gutter 11 having the same configuration as the downspout 6 is connected to the upper end of the downspout 6,
The nominal gutter 11 is inclined diagonally upward and outward, and the nominal gutter 12 is
It is also possible to drain rainwater etc. from the drainage hole of the eaves gutter 9 at the upper end by overlapping the lower and upper parts of the vertically adjacent horizontal boards in the vertical direction.
