Description

[Detailed explanation of the idea] The present invention relates to eaves gutters made of coated steel plates.

Traditionally, eaves gutters made by bending long coated steel plates such as PVC-coated steel plates or colored steel plates into gutter-like bodies have been used as particularly large eaves gutters due to their high strength. It is often cut to a predetermined width and processed into eaves gutters, and with the steel plate exposed at the cut end, this end is bent into an ear.

Therefore, the steel plate rusts from this end face due to rainwater or dew condensation, causing the covering material to peel off and impairing the durability of the eaves gutter.

Anti-corrosion paint has been applied to this end face, but this has the disadvantage that it may not be possible to apply it depending on the bent state of the ear, and the durability is poor.

The object of the present invention is to solve the above-mentioned drawbacks by fitting a cylindrical covering to the ears of an eaves gutter made of coated steel plate, and also to prevent rainwater flowing into the gutter from splashing out.

Next, the eaves gutter of the present invention will be explained with reference to the drawings.

FIG. 1 is a sectional view showing an example of the eaves gutter of the present invention, where 1 is a gutter-like body and 2 is a cylindrical covering body.

The gutter-like body 1 is made by bending a long body of a coated steel plate such as a PVC-coated steel plate or a color steel plate, and has ears 11, 11 on the side edges.
is formed.

The ears 11 may be formed in a shape similar to that seen in metal eaves gutters.

A cylindrical covering 2 is provided on the outer periphery of the ears 11, 11 of this gutter-like body 1.
are fitted.

The cylindrical covering 2 is a cylindrical body that fits around the outer periphery of the ear 11 to cover the ear 11. A slit 21 is provided in the longitudinal direction, and the base 12 of the ear 11 is held between both edges of the slit 21. The outer periphery of the ear portion 11 is covered and isolated from the outside.

It is preferable that clamping pieces 22 and 23 are formed at both end edges of the slit 21.

A plate-like body 24 is provided on the outer surface of the cylindrical covering body 2 and extends inwardly of the gutter-like body 1 along the longitudinal direction.

This plate-like body 24 protrudes inward from the trough-like body 1 from the cylindrical covering body 2 fitted to the ear part 11, so that rainwater flowing into the gutter-like body 1 flows along the gutter-like body 1. The length is such that it prevents it from flying out.

The cylindrical covering 2 is preferably made of a soft synthetic resin or rubber having elasticity, and is capable of fitting into the ear portion 11 by expanding the slit 21.

The eaves gutter of the present invention is constructed as described above, and the cylindrical covering body is fitted to the ears of the gutter-like body formed from a coated steel plate, so that the ears are isolated from the outside and form the ears. This prevents rainwater from splashing on the cut end of the coated steel plate, and also prevents dew condensation, which prevents rust from forming in the gutter-shaped body where the end of the steel plate is exposed at the edge, and increases the durability of the coated steel plate. The result is a gutter with durability.

In addition, when bending the ears, the degree of bending is too thick, which can damage the coating layer and cause rust to occur in this area, but in this invention, the entire ear is covered with a cylindrical covering, so damage to the ears is avoided. This prevents rust from forming even if

Further, since the cylindrical covering body has a plate-shaped body protruding toward the inside of the trough-shaped body, rainwater flowing into the trough-shaped body can be prevented from flowing out along the trough-shaped body.
