Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a long gutter in which rainwater flows well even at joints, does not leak rainwater, and can cope with thermal expansion and contraction.

[0002]

[Prior Art]

 As shown in FIG. 12, the conventional gutter has seam welded bending pieces, which are bent and formed substantially at right angles to the longitudinal direction, at joint portions thereof. In this case, only part of the joint is bent to the bottom side.

[0003]

[Problems to be solved by the device]

 In the conventional gutter (see Fig. 12), the bent piece part of the joint part becomes an obstacle, the rainwater flow becomes poor, and dead leaves may get stuck in the joint part. Had the drawback that the flow of rainwater was completely stagnant and overflowed from the gutter to the outside.

[0004]

[Means for Solving the Problems]

 Therefore, as a result of earnest and repeated studies to solve the above-mentioned problems, the inventor has devised the present invention to use one end side in the longitudinal direction as an outlet part and the other end side as an inlet part, and the outlet part The unit troughs, which are formed to have a smaller cross section than the inlet, are arranged in the longitudinal direction, and the outlet of one unit trough is placed in the inlet of the other unit trough and has a U-shaped cross section. By connecting the inner peripheral surface of the joint plate to the outflow port and the outer peripheral surface of the joint plate to the inflow port by seam welding, it is possible to connect rainwater to the joint part as well. The flow is extremely good, and the thermal expansion and contraction in the longitudinal direction of the gutter can be appropriately absorbed at the joint portion, which solves the above problem.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 11.

The long gutter of the present invention is composed of unit gutters A, A, ... Having appropriate lengths. The unit trough material A is formed of a metal material such as stainless steel having a plate thickness (about 0.2 mm to about 1 mm) capable of seam welding, and is formed by bending it into a substantially U-shaped cross section.

Further, the unit gutter A is formed from one metal plate when the bottom width is narrow (see FIG. 2), but when the bottom width is wide, two metal plates are seamed. The unit gutter A is formed by joining by welding (see FIG. 8).

In the unit trough material A, a bent portion between the bottom portion 1 and both side portions 2 and 2 on both sides in the width direction of the bottom portion 1 is formed in a large arc shape, and it is easy to perform seam welding in the arc portion. It is configured as

In the longitudinal direction of the unit trough A, as shown in FIGS. 1 and 2, etc., one end side thereof is the outflow port portion 3 and the other end side is the inflow port portion 4. When the unit gutters A are connected in the longitudinal direction, as shown in FIG. 1, the outflow port 3 and the inflow port 4 are connected.

The outlet part 3 is formed to have a smaller cross section than the inlet part 4. Specifically, as shown in FIG. 4, W ₁ (outlet part 3 width) <W ₂ (inlet part 4 width), and the size of the outlet part 3 is formed so that the outlet part 3 fits inside the inlet part 4.

Since the unit trough A is formed such that the cross-sectional sizes of the outflow port 3 and the inflow port 4 are different as described above, the outer shape of the unit trough A is in the longitudinal direction. It will be tapered.

The joint plate B is made of the same metal material as the unit trough material A, and its outer shape is formed in a substantially U shape as shown in FIGS. 2, 6 to 8. Specifically, the outlet connection piece 6 is formed by bending from the inner peripheral edge of the inner U-shaped cutout portion of the U-shaped partition plate 5 perpendicularly (including substantially perpendicularly) to the partition plate 5. In addition, an inflow port connecting piece 7 is formed on the outer peripheral edge of the partition plate 5 so as to be bent perpendicularly (including substantially perpendicularly) to the partition plate 5.

The outlet connection piece 6 and the inlet connection piece 7 are formed on opposite sides of the partition plate 5 as a center. The outlet connection piece 6 is entirely in contact with the outer peripheral side surface of the outlet portion 3 of the unit trough material A, and the inlet connection piece 7 is entirely contacted with the inner peripheral side surface of the inlet portion 4 of the unit trough material A. It is preferably formed so as to abut.

There is also an example in which the partition plate 5 of the joint plate B is formed with a stretchable portion 5a having a zigzag cross section as shown in FIG. 10, and the partition plate 5 is small in the plate thickness direction. It has a flexible structure.

First, the outer peripheral side surface of the outlet portion 3 of the unit trough material A is brought into contact with the outlet connecting piece 6 of the partition plate 5 of the joint plate B, and the outlet portion 3 and the outlet connecting piece 6 are separated from each other. Seam welded. Here, the edge of the outlet portion 3 is bent so that the outlet connecting piece 6 is sandwiched between the outlet portion 3 and the outlet portion 3.

Further, the inlet connection piece 7 of the partition plate 5 of the joint plate B is brought into contact with the inner peripheral side surface of the inlet 4 and seam welded (see FIGS. 2 and 3), and the edge of the inlet 4 is formed. Is formed into a folded shape with respect to the inlet connection piece 7.

Although it is generally folded as described above (see FIGS. 2 and 8), nothing may be formed (see FIG. 11).

As described above, a long gutter is constructed by connecting the outlet ports 3 of the plurality of unit gutters A, A, ... To the inlet port 4.

[Effect of the device]

 In the present invention, one end side of the longitudinal direction is the outlet part 3, the other end side is the inlet part 4, and the outlet part 3 is formed to have a smaller cross section than the inlet part 4. A are arranged in the longitudinal direction, and the outlet part 3 of one unit trough material A is connected to the inside of the inlet part 4 of the other unit trough material A through a joint plate B having a substantially U-shaped cross section. First, the rainwater flow is good because the inner circumferential surface of the joint plate B and the outer circumferential surface of the joint plate B are seam welded to the outflow port 3 and the inflow port 4, respectively. The second advantage is that the watertightness of the connection point is excellent, and the third advantage is that thermal expansion and contraction in the longitudinal direction can be coped well.

To describe these effects in detail, one end in the longitudinal direction of the unit gutter A is used as the outlet port 3, the other end in the longitudinal direction is used as the inlet port 4, and the outlet port 3 is used as the inlet port. Since the outlet portion 3 is smaller than the portion 4, the outlet portion 3 is contained in the inlet portion 4, and the joint portion B is seam welded between the outlet portion 3 and the inlet portion 4, In the direction from the outlet portion 3 to the inflow portion 4, the flow passage becomes wide, and the rainwater flow is good without any hindrance.

That is, since the joint plate B is seam-welded to the outer peripheral surface side of the outlet portion 3 of the unit trough material A and seam welded to the inner peripheral surface side of the inlet portion 4, the unit trough material A, At the seam of A, the rainwater flowing from the outlet 3 to the inlet 4 flows to the larger inlet 4 than the smaller outlet 3, so the flow is not hindered. It is a thing.

Next, since the connection between the unit gutters A, A is seam welded between the outflow port 3 and the inflow port 4 via the joint plate B, it has excellent watertightness. Is.

The outlet 3 and the inlet 4 in the joint portion of the unit gutters A and A are seam welded via the joint plate B, and the joint plate B absorbs thermal expansion and contraction. Can be done. Specifically, the swing of the joint plate B serves to absorb the expansion and contraction of the unit gutter A due to the thermal expansion and contraction corresponding to the outside air.
