Description

[Detailed Description of the Invention] The present invention relates to a vertical gutter made of a hard synthetic resin and a metal plate.

Vertical gutters, which are conventionally formed by using a metal plate as a core material and covering it with hard synthetic resin, have strong strength against dents and cracks, but the elasticity that is a characteristic of hard synthetic resin is particularly difficult for corners. In other words, because the metal core material is buried in the corners, the dimensions are restricted by the metal core material, and the elasticity of the hard synthetic resin that covers it is limited. It is not possible to absorb the dimensional error, and the adhesion of joints at corners tends to deteriorate, resulting in poor fitting.In addition, hard synthetic resin troughs with embedded metal cores In a square gutter coated with hard synthetic resin, in the corner where the core material is buried, the core material is the main material, for example, when a hard synthetic resin coating layer is formed on the inner and outer surfaces of the core material by extrusion molding. In order to determine the rectangular shape of the corner.

The dimensions of the corners are easily influenced by the square shape of the core material, and if there is a 1 dimensional error, the dimensions cannot be changed depending on the core material itself, and it is necessary to improve the dimensional accuracy of the entire culm, making formability difficult. There was a problem that it was a thing.

The present invention was made in view of the above circumstances, and its purpose is to provide a vertical gutter that can improve the fit when jointed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on drawings showing examples thereof.

FIG. 1 is a perspective view of an embodiment of the present invention.

In the figure, 1 is a vertical gutter, 2 is a corner formed in the longitudinal direction, 3 is a soft synthetic resin part, 11 is a hard synthetic resin part, and 12 is a metal plate.

The vertical gutter 1 is formed such that a thin metal plate 12 is embedded as a core material in a hard synthetic resin part 11, that is, the hard synthetic resin part 11 is coated on the inner and outer surfaces of the metal plate 12.・Ru.

Corners 2, 2 of the vertical gutter 1. ... have soft synthetic resin flesh portions 3, 3. ... is formed so as to cover the inner surface of the corner portion 2 in the longitudinal direction.

The soft synthetic resin flesh portion 3 may be formed on the inner or outer surface of the corner portion 2, or as shown in FIG.
It may be formed on both the inside and outside of the...

When the vertical gutters 1 are connected to each other by a joint or the like, the soft synthetic resin flesh portion 3 of the corner portion 2 allows the corner portion of the joint to come into close contact with the corner portion 2 of the vertical gutter 1, improving the degree of fitting.

In addition, if the soft synthetic resin flesh part 3 is formed on the outer surface, even if the vertical gutters 1 are stacked during transportation, the soft synthetic resin flesh part 3 acts as a buffer material and prevents sliding between the gutters. It is possible to prevent scratches from occurring due to movement, etc.

In summary, the vertical gutter of the present invention is a vertical gutter with a substantially rectangular cross section formed by coating the inner and outer surfaces of a metal plate core material with hard synthetic resin, and in which the vertical gutter in which the metal plate core material is embedded is vertical. The soft synthetic resin flesh portions are formed on at least one of the inner and outer surfaces of the hard synthetic resin at the corner so as to cover the corner in the longitudinal direction.

When connecting vertical gutters, it improves the fit between parts such as joints, and also improves the strength of the vertical gutters themselves, making them more resistant to dents and cracks, while also eliminating slight errors in one dimension. There is no need to worry about water leakage, and the formability of the vertical gutter is improved.
