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 in this case, the steel plate is exposed at the cut end and then processed into a new shape so that this end becomes the edge of the ear.

If the steel plate is exposed at the edge of the ear in this way, rainwater or condensation may cause the steel plate to rust from this edge, causing the coating to peel off and impairing the durability of the eaves gutter. It became.

The present invention attempts to solve the above-mentioned drawbacks by fitting a core into the ear of a coated steel plate eaves gutter and gluing the edge of the ear with an adhesive piece formed on the core. purpose.

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 core 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 colored steel plate, and ears 11, 11 are formed on the side edges.

The ear portion 11 may be formed in a shape similar to that found in metal eaves gutters, but the edge portion 12 and the ear portion 11 may be shaped so that the core body 2 can be fitted and held within the ear portion 11. Preferably, the distance from the base 13 is narrowed.

The ear portion 11 may be bent outward instead of being bent inward as shown in the figure.

The core body 2 is an elongated body made of synthetic resin and is shaped to fit inside the ear portion 11, and preferably has the same internal cross-sectional shape as the ear portion 11.

An adhesive piece 21 is formed along the circumferential surface in the longitudinal direction of the core 2, and a fitting groove 22 is formed by the adhesive piece 21 and the circumferential surface of the core 2.

The core body 2 is made integrally with the adhesive piece 21 by extrusion molding, and the adhesive piece 21 is preferably made of elastically deformable soft synthetic resin.

This core body 2 has an edge part 12 and a base part 1 in the ear part 11 of the trough-like body 1.
3, and at the same time fit the fitting groove 22 over the edge 12, and
The core body 2 is attached to the ear part 11 by adhering the edge part 12 with an adhesive piece 21.

Incidentally, if the core body 2 is made of hard synthetic resin and cannot be forcibly fitted, it may be inserted from the end of the ear part and fitted.

Preferably, the adhesive piece 21 is brought into close contact with the edge 12 of the ear 11.

For this purpose, when molding the core body 2, it is preferable to mold the core body 2 so that the tip end of the adhesive piece 21 approaches the circumferential surface of the core body 2.

The core body 2 may be adhesively fitted into the ear portion 11, and the clamping piece 21 may be adhesively bonded to the edge portion 12.

The eaves gutter of the present invention is constructed as described above, and the core body is fitted into the ear part of the gutter-like body formed from a coated steel plate, and the edge of the ear part is bonded with an adhesive piece. Even if the steel plate is exposed by cutting at the edge of the part, it is covered by adhering to the core and adhesive piece, preventing it from getting wet due to rainwater or condensation, preventing rust from forming in this part, and making it suitable for use as eaves gutters. Durability can be made comparable to that of coated steel sheets.

Further, since the core is fitted into the ear and the edge of the ear is held between the clamping pieces, the core is securely attached to the ear and will not come off.

Furthermore, since the core body is fitted into the ear, the strength of the ear is improved and the ear is not deformed when the eaves gutter is cut, so that no effort is required when connecting the eaves gutter.
