Description

[Detailed Description of the Invention] The present invention relates to a connection structure of a rectangular rain gutter.

Conventionally, the connection method for connecting rectangular rain gutters has been to apply adhesive or the like to the mating ends of the gutters, or in the case of metal rain gutters, as shown in the perspective view of Figure 5. The fitting end 31 of the trough 3 was fitted to the end of the elbow 4, and the outer periphery of the joint was soldered to secure the connection.

However, in such a conventional connection method, the soldered part is exposed to the outside, resulting in an unsightly appearance after construction, and the mating end 31 and elbow 4
In order to fit them together without any gaps, the ends must be slid into close contact with each other, which not only makes fitting difficult, but also requires dimensional accuracy in manufacturing.

Also, since the fitting end 31 is extended with a diameter reduced by one step, if the length of the eaves to be constructed and the length of the nominal gutter 3 do not match, a gap may be created between the fitting part and the fitting end 31. It was hot.

On the other hand, the connection structure of the rectangular rain gutter according to the present invention utilizes the elasticity of the side panels of the rectangular rain gutter formed of thin plate material to connect without any gaps, and unlike the conventional method, the connection part structure of the rectangular rain gutter can be connected without gaps. Since there is no fitting end with a diameter reduced by one step, the length can be adjusted and the appearance after construction is good.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an exploded perspective view of a rectangular pipe 1 with an open top and an elbow 2 according to the present invention. The pipe 1 is formed by bending a metal plate into a substantially U-shaped cross section. , 13 are extended with L-shaped flanges 11, 11, and protrusions 12, 12 are provided at the lower corners to further ensure reinforcement and fitting.

On the other hand, a U-shaped notch 21 is formed on the upper surface of the elbow 2, which has a substantially rectangular cylindrical shape in cross section, from the water side to the water bottom side, and the flange 2 is formed on the periphery of this U-shaped notch 21.
2 is vertically installed, and a decorative recess 2 is provided on the side of the elbow 2.
3 is provided.

This U-shaped notch 21 is provided to facilitate fitting of the nominal gutter 1, and after fitting and connecting, it is also possible to further solder the inner surface of the fitted joint from above.

Fig. 2 shows a perspective view in the middle of fitting the nominal gutter 1 to the end of the elbow 2. Adhesive is applied to the inner peripheral surface of the end of the elbow 2, and both sides 13, 13 of the nominal gutter 1 are slightly tightened. Insert the flange portion 11 in a compressed manner.
while inserting the flange 22 of the elbow 2.

FIG. 3a is a cross-sectional end view of the fitted portion at this time.

Nominal gutter 1 inserted into elbow 2 as described above
If the sides of the pipe are pushed outward as shown in Fig. 3b and fitted together, the nominal gutter 1 will be formed as shown in the perspective view of Fig. 4.
and elbow 2 can be connected and fixed.

Since the fitted portions are fitted using the elasticity of the side surfaces 13, there is no risk of creating a gap, and the protrusions 12 formed at the lower corners make them even stronger.

As described above, the connection structure of a rectangular gutter according to this invention utilizes the elasticity of the side of the gutter to fit together, compared to the sliding fit shown in the conventional example, making it easier to install, and the connection and fixation can be securely achieved by sandwiching an adhesive therebetween, and the appearance after installation is also good.
