Description

[Detailed Description of the Invention] The present invention relates to a drain pipe joint for a gutter.

Rainwater flowing down from a gutter is often drained straight to the ground, but in urban areas with complete sewerage systems, it may be drained into the sewer system using drainage pipes.

In this case, the gutter and the drain pipe are connected using a joint, and the present invention relates to this drain pipe joint, so that even if the gutter has a different thickness, the connection can be made in accordance with the difference in thickness.

The present invention will be explained in detail below with reference to illustrated embodiments.

Figure 1 shows a substantially short cylindrical drain pipe joint 1 according to the present invention.
FIG. 2 is a longitudinal sectional view thereof.

This drain pipe joint 1 has an upper body 16 whose diameter is tapered upward and a lower body 13 whose diameter is tapered downward, which are fitted at the center, and are made of thin metal plate. It is made of synthetic resin, but it is also possible to use synthetic resin.

The upper body 16 tapers upward in diameter, has an insertion hole 11 at its upper end into which a gutter is inserted, and has a plurality of concentric slits 12 formed on the tapered slope.

This concentric slit 12 is used to widen the insertion hole by cutting out the slit portion when the diameter of the hard trough to be inserted into the insertion hole 11 is different.

That is, in FIG. 2, the insertion hole 11 with a diameter of d is formed in the minimum case, but by cutting out the concentric slit 12, the diameters can be changed to a, respectively.
The insertion holes 11 of b and c can be easily formed, and even if the thickness of the gutter differs, it can be quickly handled and constructed.

On the other hand, the lower body 13 connected to the drain pipe 3 is formed in a tapered shape with a diameter reduced downward, and can be inserted into the drain pipe 3 to form a drain pipe 3 of any thickness as shown in the cross-sectional view of FIG. This is something that can be handled.

Figure 3 shows a cross-sectional view of the main parts when the hard gutter 2 and the drain pipe 3 are connected, and Figure 4 shows a side view when it is installed on a building. The slit 12 is cut out to form an insertion hole 11 having a diameter b.

As mentioned above, the drain pipe joint according to the present invention can be used to quickly connect a gutter and a drain pipe by cutting out a slit to form an appropriate insertion hole even if the thickness of the gutter to be connected changes. It has the advantage of being able to be constructed in accordance with the requirements of the construction industry and having a good appearance after construction.
