Description

[Detailed description of the invention] 3. Detailed description of the invention [Technical field] The present invention relates to a rain gutter with excellent durability.

[Background technique? lJ] Traditionally, the W1 gutter has been made of metal to improve its durability, but after a long period of time, the parts that come into continuous contact with rainwater 3, for example, the eaves 4JA shown in Figure ttS6.
'', the inner surface 2, especially the bottom region, became thin and torn due to wear and corrosion caused by rainwater, causing leakage.

[Objective of the Invention 1 The present invention has been made in view of the above circumstances, and its purpose is to provide a material that is durable, does not cause leakage even after long-term use, and is inexpensive. Our goal is to provide rain gutters.

[Disclosure 1 of the Invention The rain gutter of the present invention is formed by providing a resin M4 with excellent wear resistance and corrosion resistance in the region R of the inner surface 2 of the metal rain gutter body 1 that is continuously in contact with rainwater 3. With this configuration, the above object can be achieved. That is, the rain gutter body 1 is made of metal to increase its mechanical strength, and a grease layer 4 with excellent wear resistance and corrosion resistance is formed on the inner surface of the rain gutter body 1 to prevent wear and corrosion caused by rainwater. This makes it possible to improve durability, and in addition, since the fat layer 4 is provided only in the region R of the inner surface 2 of the rain gutter body 1 that is in continuous contact with rainwater, it is possible to improve the durability at a relatively low cost. In addition, since the resin layer 4 is on the inner surface 2, it does not become unsightly even if the resin layer 4 is not provided on the entire surface.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In the embodiment shown in FIGS. 1 and 2, rain @A is
Nominal gutter A connected to the water collector 6 attached to the eave gutter 5;
and anglerfish A2. The rain gutter body 1 of the gutter A and the anglerfish A2 is formed into a cylindrical shape in the width direction by metal such as an iron plate or a copper plate. A resin layer 4 having excellent abrasion resistance and corrosion resistance is provided in a region R1 of the inner surface 2 of the rain gutter body 1 that is continuously in contact with rainwater 3, that is, in a lower portion in the installed state. This resin/
The resin forming I4 is preferably a resin having excellent heat resistance, such as a 7-wire resin or polycarbonate. The resin layer 4 is formed integrally with the rain gutter body 1 by extrusion molding, by welding a resin I'W film, or by coating with a resin.In the embodiment shown in FIG. Rain gutter A is vertical gutter A, and the outdoor side surface of the inner surface of the stepped part formed by bending toward the indoor side of the rain gutter body 1 becomes lJA area R where it continuously comes into contact with rainwater 3.These implementations In this example, since the resin layer 4 is expensive, an inexpensive general-purpose resin layer 7 such as vinyl chloride resin or acrylic resin is interposed between the inner surface of the rain gutter body 1 and the rain gutter body 1, as shown in Fig. fjS4. In addition, m
As shown in FIG. 5, a transparent resin layer 8 may be provided on the outer surface of the rain gutter body 1.

[Effect of the invention 1] In the present invention, a resin layer with excellent abrasion resistance and corrosion resistance is provided on the inner surface of the metal rain gutter main body in a region that is continuously in contact with rainwater, so that the rain gutter main body It is made of metal to increase mechanical strength, and a resin layer with excellent wear and corrosion resistance is formed on the inner surface of the rain gutter body to prevent wear and corrosion caused by rainwater, improving durability. Moreover, since the resin layer is only provided on the inner surface of the rain gutter body in areas that are in continuous contact with rainwater, it can be manufactured relatively inexpensively, and since it is on the inner surface, it will not be unsightly even if the resin layer is not provided on the entire surface. It never becomes.
