Description

[Detailed Description of the Invention] The present invention relates to a gutter, and more particularly to a gutter that is attached to the eaves of a long roof and can receive a large amount of rainwater.

For example, on roofs with extremely large projected areas and long roof eaves, such as gymnasiums and factory buildings, extremely long gutters are attached to the eaves while forming a slope, so that they can be installed at the downstream side of the eaves as shown in Figure 3. This had the disadvantage that the gap between the pipe and the gutter was large, increasing the chance of rainwater splashing around.

In addition, as shown in Figure 4, in the case where the side wall of the gutter is gradually increased from one side to the other so that the gap between the eaves and the gutter does not widen, this long gutter is made of tin plate or vinyl chloride resin. Since the shape was formed by hand processing such as bending the plate, it took a lot of time and effort to measure the dimensions, making it impractical.

The gutter of the present invention solves the above-mentioned conventional drawbacks, and its gist is that a protrusion is provided on the inner side of the upper edge of a plurality of gutter units each having a substantially groove-shaped cross section. One of the gutter units is slidably fitted to the other gutter unit, and the upper edge of the one gutter unit is in contact with the lower part of the protrusion of the other gutter unit.

An example of the present invention will be described below with reference to the drawings.

The gutter unit 1 has a substantially rectangular groove shape in cross section, and protrusions 2, 2 are provided inside the upper edge of the gutter unit 1, and are formed in the same cross-sectional shape from one end to the other end.

The gutter unit 3 has a substantially rectangular groove shape in cross section, and protrusions 4, 4 are provided on the inner side of the upper edge of the gutter unit 3.

The gutter unit 3 is formed to have the same cross-sectional shape from one end to the other end.

The width between the outer surfaces of the side walls of the gutter unit 1 is approximately equal to the width between the inner side walls of the gutter unit 3, and the height from the outer surface of the bottom wall of the gutter unit to the upper edge is equal to the width between the inner surface of the bottom wall of the gutter unit 3 and the protrusion 4. The height is approximately equal to that of the previous one.

The gutter unit 1 is fitted into the gutter unit 3, and the upper edge of the gutter unit 1 is brought into contact with the lower part of the protrusions 4, 4 of the gutter unit 3, so that the gutter unit 1 and the gutter unit 3 slide almost smoothly. It can be done freely.

The gutter unit 5 has a substantially rectangular groove shape in cross section, and has a protrusion 6 on the inside of the upper edge.
, 6 are provided.

The gutter unit 5 is formed to have the same cross-sectional shape from one end to the other end.

The gutter unit 3 is fitted into the gutter unit 5, and the upper edge of the gutter unit 3 is brought into contact with the lower part of the protrusions 6, 6 of the gutter unit 5.

Since the gutter units 1, 3.5, etc. constituting the gutter of the present invention have the same cross-sectional shape from one end to the other, the gutter units 1, 3.5,... It can be integrally extruded from resin, and it is easy to measure dimensions even when bending or welding a tin plate or a vinyl chloride resin plate.

In this way, the gutter of the present invention, which is composed of a plurality of gutter units 1, 3.5..., has the water stop wall 7 connected to one end of the gutter unit 1, The length of the gutter is adjusted by sliding them respectively, and the water stop wall body 7 is installed on the upstream side 9 while forming the required slope along the eaves 8 of the roof.

The distance between the upper edge of the iron bridge and the eaves 8 does not become large even on the downstream side 10, and rainwater does not scatter around.

Rainwater flows from the upstream side 9 to the downstream side 10, but since there is a level difference between the individual gutters and the connecting parts of the individual gutters, shallow water rarely occurs. .5・
...You can also glue the comrades together.

Further, the flow rate of rainwater increases as it reaches the downstream side 10, but since the gutter 5 on the downstream side 10 is wider and taller than the gutter 1 on the upstream side 9, the drainage capacity is also large and the rainwater is will not overflow from the gutter.

Since the gutter of the present invention has the above structure, by assembling multiple gutter units, it can be attached to the eaves of a roof while adjusting the length and slope. It is possible to avoid creating a large gap between the edge and the eaves.

In addition, the gutter of the present invention can be used as a single gutter with the same cross-sectional shape from one end to the other, and can be easily manufactured in large quantities. can be selected to form a gutter that matches the flow rate of rainwater.
