Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for a gutter having a bottom plate, a front plate and a rear plate.

[0002]

2. Description of the Related Art Conventionally, a bottom plate, a front plate, and a rear plate are provided, and as shown in FIG. 5, the front plate has a bent portion B which is bent substantially forward and upward. The eaves gutter A with a beautiful appearance has been proposed. That is, the eaves gutter A is formed by coating both surfaces of a metal plate such as a steel plate with a synthetic resin material, and is inclined rearward so as to be continuous with the roof surface as the front plate 3 moves upward. Further, the front ear D is provided obliquely downward and longitudinally from the upper end of the front plate upper portion C such that the width of the upper surface opening is smaller than the inner width.

In this case, when connecting the eaves gutters A in the longitudinal direction, the ends of the other eaves gutters A are inserted into one pair of eaves gutters and bonded, or the ends of the paired eaves gutters A are joined together. Abutting, as shown in FIG. 4, an inner holding member F of a joint of a predetermined length made of a synthetic resin material having a contact piece G, for example, which is substantially in contact with the inner surface of the eaves gutter A, is attached from the upper surface opening, An adhesive is interposed between the inner surface of the eaves gutter A and the outer surface of the inner holding member F, and substantially abuts the outer surface of the eaves gutter A, and engages with the front ear D and the rear ear E of the eaves gutter A. The outer joint H having the front ear engaging portion and the rear ear engaging portion was bonded and connected so as to grip the rear ear E at the upper end of the rear plate 4 and the front ear D at the upper end of the upper front plate.

[0004]

However, in the above-mentioned conventional technique, when the front plate of the eaves gutter has a plurality of bent portions, for example, and the shape thereof is complicated, the inner holding member of the joint is replaced with an outer shape. Even if a mold is manufactured to match the complex inner surface shape of the eaves gutter, the inner shape of the eaves gutter may not conform to the inner holding member due to variations in the amount of molding shrinkage when manufacturing the eaves gutter. Was. For this reason, the inner side of the eaves gutter cannot be brought into close contact with the outer surface of the inner holding member, and when the adhesive does not sufficiently spread, a gap may be formed at a connection portion between the eaves gutters. Therefore, in order to prevent rainwater from leaking from the connection part, the outer joint as described above is indispensable, and when the step at the connection part becomes an aesthetic problem, a complicated external shape is required. An eaves gutter having a front panel could not be installed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to eliminate water leakage from a connecting portion by using only an inner holding member, and to provide a complex eaves-shaped eaves. An object of the present invention is to provide a connecting structure of an eaves gutter capable of eliminating a step at a connecting portion between the gutters.

[0006]

According to the present invention, there is provided a connecting structure for an eaves gutter comprising a bottom plate, a front plate, and a rear plate. The inner surface of the front plate, the bottom plate, and the rear plate abuts against the inner surface of the eaves gutter main body, and the inner holding member provided with the fitted portion on the outer surface is attached to the bottom plate, the front plate, or the rear plate. Are inserted and connected inside the eaves gutter main body provided with a fitting portion to which the fitting is fitted.

In this case, an eaves gutter body having a bottom plate, a front plate and a rear plate has an outer surface of a front plate, a bottom plate and a rear plate abutting against an inner surface of the eave gutter body, and a fitting portion is provided on the outer surface. The fitted portion of the inner holding member is fitted and inserted into the fitting portion inside the eave gutter body provided on any of the bottom plate, the front plate, and the rear plate.

The front plate and the rear plate have upper and lower front ears and rear ears projecting inwardly of the eaves gutter body, respectively, and grooves arranged in parallel with the front and rear ears. Preferably, the upper ends of the front plate and the rear plate of the inner pressing member are respectively engaged with the grooves.

In this case, the inner holding member is provided with the upper ends of the front plate and the rear plate juxtaposed with the front ear and the rear ear projecting inward to the upper portions of the front plate and the rear plate of the eaves gutter body. By engaging with the groove, the fitted portion is fitted to the fitting portion of the eave gutter main body, and inserted and connected inside.

[0010] The front plate has a plurality of bent portions bent substantially forward and upward, and has a fitting portion formed on the inner surface of the front plate as a ridge projecting from the base end of the bent portion toward the inside of the eaves gutter body. It is preferable that the fitting portion is formed as a concave portion that opens to the front side of the front plate of the inner pressing member corresponding to the ridge.

In this case, the inner holding member has the upper ends of its front and rear plates juxtaposed with the front and rear ears projecting inward above the front and rear plates of the main body of the eaves gutter. By engaging with the groove, the recess opening to the front side of the front plate is formed from the base end of the plurality of bent portions corresponding to the recess continuously provided on the inner surface of the eave gutter main body. The protruding ridges projecting inward are fitted and inserted inside and connected.
