Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long gutter capable of flowing rainwater well even at a joint portion, free of rainwater leakage, and capable of coping with thermal expansion and contraction.

[0002]

2. Description of the Related Art As shown in FIG. 12, in a conventional gutter, bent pieces formed to be bent substantially at right angles to a longitudinal direction are seam-welded at joint portions thereof. In this case, only a part of the joint is bent toward the bottom surface.

[0003]

In the conventional gutter (see FIG. 12), the bent portion of the joint portion becomes an obstacle, and the flow of rainwater becomes poor, and dead leaves and the like are clogged in the joint portion. In such a case, there is a disadvantage that the flow of rainwater completely stagnates and overflows from the inside of the gutter.

[0004]

Means for Solving the Problems In order to solve the above problems, the inventor of the present invention has made intensive studies, and as a result, the inventor has found that one end in the longitudinal direction is an outlet and the other end is an inlet. And the outlet portion of the unit gutter material formed as a cross section smaller than the inlet portion in the longitudinal direction, and the outlet portion of one unit gutter material is placed in the inlet portion of the other unit gutter material. By connecting via a joint plate having a substantially U-shaped cross section, the inner peripheral surface of the joint plate is connected to the outlet, and the outer peripheral surface of the joint plate is formed as a long gutter by seam welding to the inlet. Also, the flow of rainwater is extremely good at the joint part, and the joint part can appropriately absorb the thermal expansion and contraction in the longitudinal direction of the gutter, thereby solving the above problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The long gutter of the present invention is composed of unit gutter members A, A,... Having an appropriate length. The unit gutter material A has a thickness that can be seam welded (from about 0.2 mm to about 1 mm).
mm) of a metal material such as stainless steel, which is bent and formed into a substantially U-shaped cross section.

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

In the unit gutter 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 so that seam welding in the arc portion can be easily performed. Is configured.

In the longitudinal direction of the unit gutter material A, as shown in FIGS. 1 and 2, one end side is an outlet port 3 and the other end is an inlet port 4. Unit gutter material A
When connecting in the longitudinal direction, the outlet 3 and the inlet 4 are connected as shown in FIG.

[0010] outlet portion 3 is formed such that sectional small than the inflow opening 4, specifically, as shown in FIG. 4, W ₁
(Width of the outlet 3) <W ₂ (width of the inlet 4), and the outlet 3 is formed in such a size as to fit in the inlet 4.

Since the unit gutter material A is formed so that the cross-sectional sizes of the outlet 3 and the inlet 4 are different as described above, the outer shape of the unit gutter A is tapered in the longitudinal direction. It will be formed in the shape.

The joint plate B is formed of the same metal material as the unit gutter material A. As shown in FIGS. 2, 6 to 8,
Its outer shape is formed in a substantially U-shape. Specifically, U
From the inner peripheral edge of the inner U-shaped cutout of the partition plate 5 having a U-shape, the outlet connection piece 6 is formed by being bent perpendicularly (including substantially perpendicularly) to the partition plate 5, and the partition plate 5 is formed. Is perpendicular to (including substantially perpendicular to) the partition plate 5
An inflow-port connecting piece 7 is formed to bend.

The outlet connection piece 6 and the inlet connection piece 7 are formed on opposite sides of the partition plate 5. The outlet connection piece 6 is entirely in contact with the outer peripheral side of the outlet 3 of the unit gutter material A, and the inlet connection piece 7 is entirely in contact with the inner peripheral side of the inlet 4 of the unit gutter material A. Preferably, it is formed so as to abut.

Further, the partition plate 5 of the joint plate B includes
As shown in FIG. 10, there is also an embodiment in which an elastic portion 5a having a zigzag cross section is formed, and the partition plate 5 is configured to be able to slightly expand and contract in the thickness direction.

First, the outer peripheral side surface of the outlet 3 of the unit gutter 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 3 and the outlet connecting piece 6 are connected. Seam welded. Here, the edge of the outlet portion 3 is bent so as to sandwich the outlet connecting piece 6 and is formed in a folded shape.

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 is seam-welded (see FIGS. 2 and 3). Are formed on the inlet connection piece 7.

As described above, it is common to make a break (see FIGS. 2 and 8), but sometimes nothing is formed (see FIG. 11).

As described above, a plurality of unit gutter members A,
By connecting the outlet 3 of A,... To the inlet 4, a long gutter is constructed.

[0019]

According to the present invention, one end in the longitudinal direction is defined as an outflow port 3, the other end is defined as an inflow port 4, and the outflow port 3 is formed to be smaller in cross section than the inflow port 4. The unit gutter members A, A are arranged in the longitudinal direction, and the outlet 3 of one unit gutter A is inserted into the inlet 4 of the other unit gutter A via a joint plate B having a substantially U-shaped cross section. And the outer peripheral surface of the joint plate B is seam-welded to the inflow port 4 to form a long gutter. Secondly, various effects such as excellent watertightness of the connecting portion, and thirdly, a favorable response to thermal expansion and contraction in the longitudinal direction can be obtained.

These effects will be described in detail. One end of the unit gutter material A in the longitudinal direction is an outlet 3 and the other end in the longitudinal direction is an inlet 4, and the outlet 3 is an inlet. Since the outlet 3 is accommodated in the inlet 4 and the outlet 3 and the inlet 4 are seam-welded at the joint plate B, the outlet 3 In the direction from the part 3 to the inflow part 4, the flow path becomes wide, and the flow of the rainwater flows well without any hindrance.

That is, since the joint plate B is seam-welded to the outer peripheral surface side of the outlet 3 of the unit gutter material A, and is seam-welded to the inner peripheral surface side of the inlet gutter A, the unit gutter material A, At the seam portion A, the rainwater flowing from the outlet 3 to the inlet 4 flows into the inlet 4 larger than the small outlet 3, so that the rainwater does not hinder the flow at all. It is.

Next, since the connection of the unit gutter members A, A is performed by seam welding the outlet 3 and the inlet 4 via the joint plate B, the unit has excellent watertightness. It is.

The outlet 3 and the inlet 4 at the joints of the unit gutter members A, A are seam-welded through the joint plate B, so that the thermal expansion and contraction can be absorbed by the joint plate B. Can be done. In particular,
When the unit plate gutter material A thermally expands and contracts in response to the outside air due to the swing of the joint plate B, it plays a role of absorbing the expansion and contraction.
