Abstract

(57) [Summary] (Corrected) [Purpose] To prevent water leakage due to accumulation of dust and the like in eaves joint joints made of synthetic resin that can absorb expansion and contraction of eaves troughs due to changes in temperature. [Structure] A joint main body A and a joint member B slidably contacted with each other are provided between a base end portion of an eaves gutter connection portion 1 of the joint main body and a free end portion of a sliding portion 4 of the joint member. It is a synthetic resin eaves gutter joint formed by stretching a bellows-like covering film so as to shield it.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin eaves trough joint, and more particularly to a synthetic resin eaves trough joint capable of absorbing expansion and contraction of the eaves trough due to changes in temperature.

[0002]

[Prior art]

 Conventionally, as a synthetic resin eaves gutter joint of this kind, as seen in Japanese Utility Model Publication No. 60-124430, etc., one end is provided on the inner peripheral surface of the other end of the joint body having an eaves gutter connection at one end. It is generally used that the other end of the joint member having the eaves gutter connection portion is slidably abutted via a sealing material along the width direction.

[0003]

[Problems to be solved by the device]

 However, with the above-mentioned synthetic resin eaves gutter joint, after the operation, the dust that has flowed down from the roof surface and accumulated on the eaves gutter on the water side flows down with rainwater onto the joint body located on the water side. , The sliding part of the underwater joint member that slides as the eaves gutter expands and rides on the dust accumulated on the sliding part of the joint body, and the sliding part side of the joint member floats up. Also, the above dust flows into the seal material, and as a result, a gap is created between the joint body and the joint member that are in contact with each other via the seal material along the width direction, and the seal is provided for waterproofing. There was a problem that water leaked because the material could not fulfill its function.

The present invention was devised to eliminate the drawbacks of the conventional products described above, and it is an object of the invention to provide a synthetic resin eaves gutter joint in which the deterioration of the waterproof function due to the flow and accumulation of dust is prevented. It is a thing.

[0005]

[Means for Solving the Problems]

 The present invention has been made in view of the above, and includes a joint body having an eaves gutter connection portion at one end and a sliding portion at the other end, and an eaves gutter connection portion at one end and the other end portion. A joint member having a sliding part on the inner surface of the sliding part of the joint body slidably abutting, the base end part of the eaves gutter connection part of the joint body A synthetic resin eaves gutter joint characterized in that a bellows-like covering film bent in a U shape is stretched so as to shield between the free end of the sliding part of the joint member. .

The bellows-shaped covering film is fixed to the base end of the eaves-spout connecting part of the joint body and the free end of the sliding part of the joint member by adhesion, respectively. If necessary, a sealing material along the width direction may be interposed between the joint member and the joint member.

[0007]

[Action]

 The eaves trough joint made of synthetic resin of the present invention is a bellows shape bent in a U shape so as to shield between the proximal end of the eaves gutter connection portion of the joint body and the free end of the sliding portion of the joint member. Dust flows down from the water side because the covering film is stretched, but dust flows down on the bellows under the water through the bellows-like covering film, and since a sealing material is not always necessary. There is no water leakage due to deterioration of the function of the sealing material, such as floating of the joint member due to riding on dust.

【Example】

 1 is a perspective view showing an embodiment of a synthetic resin eaves gutter joint of the present invention, and FIG. 2 is a synthetic resin eaves gutter of the present invention. It is sectional drawing which shows the use condition of one Example of a joint.

[0009] In the figure, A has an eaves gutter connecting portion 1 provided at one end for connection of an eaves gutter C on the water side, and a sliding portion 2 at the other end from a substantially U-shaped cross section. It is a joint body.

In the figure, B is a joint member having a substantially U-shaped cross section which is slidably mounted on the inner surface of the sliding portion 2 of the joint body A, and has one end of the underwater eaves gutter C. The eaves gutter connection portion 3 provided for connection is provided, and the sliding portion 4 that slides on the sliding portion 2 of the joint body A is provided on the other end side.

The base end portion of the eaves gutter connection portion 1 of the joint body A and the free end portion of the sliding portion 4 of the joint member B have a bellows shape bent in a U-shape so as to shield them from each other. A covering film 5 is stretched, and a sealing material 6 is mounted between the joint body A and the joint member B along the width direction.

[0012]

[Effect of device]

 As is clear from the above, the synthetic resin eaves gutter joint of the present invention has the eaves gutter connection part at one end and the sliding part at the other end, and the eaves gutter connection part at one end. A joint member having a sliding portion at the other end, and the joint member slidably abutting on the inner peripheral surface of the sliding portion of the joint body, the base of the eaves gutter connection portion of the joint body. Since a bellows-shaped covering film bent in a U shape is stretched so as to shield between the end portion and the free end of the sliding portion of the joint member, dust flows down from the water side. The dust passes through the bellows-like covering film and flows down onto the eaves gutter on the underwater side. Water leakage due to deterioration is prevented.
