Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an eaves gutter connection structure using a gutter joint.

(Conventional technology) Conventionally, li! The connection structure for eaves gutters using l-joints is as follows:
For example, the one described in Japanese Utility Model Application Publication No. 52-19724 is known.

This conventional connection structure connects the eaves gutter by inserting the end of the eaves gutter inside the gutter joint, and the gutter joint and the eaves gutter are formed in a single cross-sectional shape, The inner surface JFg shape and the outer surface shape (iT-M) are formed to have substantially the same shape.

(Problem to be solved by the invention) Therefore, in such a conventional eaves gutter connection structure,
Since the external shape of the gutter joint is larger than the external shape of the eaves gutter,
There was a problem that a difference in level equal to the wall thickness of the gutter joint appeared on both sides of the gutter joint, resulting in an unsightly appearance.

Therefore, the present invention addresses the above-mentioned conventional problems and aims to provide an eaves gutter connection structure that does not show any level difference on both sides of the gutter joint and has a good appearance.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the connection structure of the rods and gutter of the present invention is such that the eaves gutter is connected to the gutter. In the eaves gutter connection structure in which the eaves gutter is connected by inserting the longitudinal end into the inner hole 11 of the joint, the longitudinal end of the eaves gutter is connected. It is formed in a connecting part whose front outer surface is internally recessed than other parts, and the inner shape of the gutter joint is formed to be equal to the external shape of the connecting part, and the wall thickness of the gutter joint is smaller than that of the connecting part. The depth of the dent is approximately equal to the depth of the dent.

(Function) In the eaves gutter connection structure of the present invention, the connecting part of the eaves gutter is inserted inside the gutter joint, so that the part of the eaves gutter other than the connecting part is exposed outside, and the gutter joint is completely closed. It's shown outside. and,
The connection part of the eaves gutter is formed by recessing the outer surface of the front part inward from the part other than the connection part, and the wall thickness of the gutter joint is formed to be approximately equal to the depth of the recess of the connection part. , the front outer surface of the gutter joint and the front outer surface of the portion of the eaves gutter other than the connection portion are flush and continuous.

(Example of actual gallery) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of an actual example will be explained based on FIGS. 1 to 3.

Figure 1 is a perspective view showing the eaves gutter connection structure of this embodiment.
2 is the eaves gutter, and 2 is the gutter joint.

The eaves gutter 1 is a round gutter made of synthetic resin and has a semicircular cross section, and hollow ears 1111 are formed at both ends in the circumferential direction. In addition, the longitudinal end of this eaves gutter l has an ear 11.1.
1 is formed as a connecting portion l2 which is more recessed than other parts, and the recess depth D is uniform over the entire circumferential direction.

The eaves gutter 1 can be manufactured by simply extruding a general eave gutter and then subjecting it to a simple post-processing process such as heating and shrinking the longitudinal ends.

The gutter joint 2 is formed with a wall thickness T that is approximately equal to the recess depth D of the connecting portion l2 of the eaves gutter l. The inner surface shape is formed to be equal to the outer surface shape of the connecting portion l2 of the eaves gutter I, and the outer surface shape is the same as that of the connecting portion l2 of the eaves gutter I. It is formed equally to the external shape. Furthermore, an ear receiver 21.2L is formed at the circumferential end of the joint body 2 over the entire length in the longitudinal direction.

FIG. 2 is a side view showing the connection structure of the eaves gutter (2), and FIG. 3 is a sectional view showing the connection structure of the eaves gutter (2).

As shown in these figures, the eaves gutter I has a connecting portion i2 inserted inside the M joint 2, and an ear receiver 2L of the gutter joint 2. 21 by fitting the ears 11.11 of the connecting portion L2 into the connecting portion L2.

That is, the parts of the eaves gutter L other than the connection part I2 are exposed to the outside, and the entire gutter joint 2 is exposed to the outside. And said eave II
The connecting part 12 is formed by being recessed internally as a whole than the part other than the connecting part I2, and the gutter joint 2 is formed so that the wall thickness T is almost equal to the recess depth D of the connecting part I2. Therefore, it is continuous and flush with the outer surface of the gutter joint.

In this way, the eaves gutter connection structure of this example has a good appearance because no step appears on both sides of the gutter joint 2.

Although the practical example of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this practical example, and even if there are design changes within the scope of the present invention, the present invention include.

For example, in the actual gallery example, a connection part was formed at the end of the eaves gutter, which was recessed inward as a whole, but the connection part should preferably be recessed on the front outer surface and the bottom outer surface, and the rear outer surface should be recessed. It may be a part other than the connection part and a surface, or it may be protruded for post-processing.

Note that it is advantageous to make the rear outer surface protrude in order to secure a flow area for rainwater. In any case, since the rear part of the eaves gutter is not noticeable when attached to the eaves, a good appearance can be obtained by having the front outer surface of the gutter joint and the front outer surface of the eaves gutter flush and continuous.

Furthermore, when forming the connection part in the eaves gutter, the outer surface of the end part may be recessed more than the other part by making the wall thickness of the end part thinner.

Furthermore, although the embodiments have been described using a round gutter as an example, the present invention can also be applied to a rectangular gutter with a groove-shaped cross section. In the case of this rectangular gutter, it is necessary to form a connecting portion by recessing at least the outer surface of the front wall more inward than the other portions.

(Effects of the Invention) As explained above, in the eaves gutter connection structure of the present invention, the front outer surface of the gutter joint and the front outer surface of the portion of the eaves gutter other than the connection portion are flush with each other. Since it is continuous and there are no steps on both sides of the gutter joint, the effect is that it looks good.
