Description

[Detailed Description of the Invention] The present invention relates to a connection structure between a drain pipe and a gutter.

A water collector is attached to the eaves gutter constructed at the eaves of a building, and a drain pipe is connected to the bottom of this water collector, and a gutter, elbow, etc. are connected in sequence to guide rainwater to the vertical gutter. be.

Conventionally, the connection between a metal drain pipe and a gutter has been to fit the fitting ends of each other, and to connect and secure the periphery of the joint by soldering from the outside.

However, this connection work by soldering requires skill and is inefficient, and the appearance is not good because the soldered parts are exposed on the outside.

The present invention eliminates these conventional drawbacks,
A drain pipe that is easy to construct and can be securely connected also provides a connection structure for a gutter.

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

Figure 1 is a side view when rain gutters are installed at the eaves, and the rainwater collected in the water collector 1 is drained to the ground through the drain pipe 2, the gutter 3, the elbow 4, and the vertical gutter 5. be done.

At this time, the gutter 3 located under the eaves is cut to a length that matches the length of the eaves and connected to the drain pipe 2 and the like.

FIG. 2 is an exploded perspective view of the ends of the drain pipe 2 and the gutter 3. One end of the drain pipe 2, which is made of a metal plate such as a copper plate and has a substantially rectangular tube shape, has a square tube-shaped fitting end. The part 21 is extended, and the center of the upper surface of the fitting end part 21 is connected to the stepped part 2.
2, and an oval engagement hole 23 is bored near the center.

On the other hand, the top of the gutter 3, which is open at the top and has a substantially U-shaped cross section, is formed by bending the upper ends of both sides inward to form a flange portion 33, and further bending the tip downward to form a hanging portion 32. 〓It has a shape.

Engagement grooves 33 are cut into the tip of this hanging part 32 in a sawtooth shape at regular intervals, and the engagement grooves 33 enable connection even if the nominal gutter 3 is cut at an arbitrary position. A large number of them are formed for this reason.

The engagement piece 24 is formed by bending a slightly thick metal plate of about 0.8 mm, and one edge is raised to form the upright portion 25.
is formed, and an engagement hole 26 with a threaded groove for screwing is bored in the center.

When performing connection work, cut the gutter 3 to match the eaves, and connect the end to the fitting end 2 of the drain pipe 2.
1, and then the engagement piece is brought into contact with the inner upper surface of the fitting portion, and the upright portion 25 is engaged with the sawtooth engagement groove 33, and then the engagement hole 2 is inserted from above.
3 and the engagement hole 26 are fixed with screws.

At this time, the engagement grooves 33 are formed at appropriate intervals, but these intervals are shorter than the long diameter of the oval engagement hole 23, so the nominal gutter 3 can be cut at any position. The screws 27 can also be used to securely connect and secure the connections. FIG. 3 is a perspective view of the connection part when the connection is fixed, and FIG. 4 is a cross-sectional view of the fitting connection part. Since it is fixed to the fixing plate 24, and the fixing plate 24 is engaged and connected to the engagement groove 33 of the trough 3, the drain pipe 2 and the trough 3 can be reliably connected and fixed.

Further, when fitting, an adhesive or the like can be applied to the outer periphery of the fitting end portion 21 to make the connection even stronger.

As described above, the connection structure between the drain pipe and the gutter according to the present invention does not require skilled work such as soldering as in the past, and only requires fixing the fixing plate with screws, making the work easy. Moreover, it can be securely connected and fixed.
