[Prior art]

 Conventionally, there are various eaves trough joints, but as the most general eaves trough joint, as described in Japanese Patent Publication No. 49-3083, a joint part whose inner surface is almost the same as the outer circumferential surface of the eaves trough is formed at both ends. There is known an eaves trough joint including a joint body and an ear holding portion which is provided on both side edges of the joint body and is fitted into an ear portion of the eaves trough. The eaves gutter joint is coated with adhesive on the inner surface of the joint and the outer peripheral surface of the eaves gutter, respectively, and the inner surface of the joint of the eaves gutter joint is pressed against the outer peripheral surface of the eaves gutter to bond the eaves gutter. To do.

When the eaves gutters are connected by the eaves gutter joints in this manner, the eaves gutter joint and the eaves gutter are firmly fixed with an adhesive. If the eaves trough and eaves trough joint are firmly fixed with an adhesive in this way, the eaves trout may expand under hot weather in summer, resulting in meandering of the eaves trough or damage to the eaves trough joint. However, there is a problem that the eaves gutter contracts on a cold day in winter, and as a result, the eaves gutter may crack or the joint surface between the eaves gutter and the eaves gutter joint may separate.

Various eaves gutter joints are conventionally known as eaves gutter joints for solving such a problem. For example, as described in JP-B-58-6984 and JP-B-58-45386, a bellows is provided between the central part or the left eaves gutter joint and the right eaves gutter joint, and the bellows is elastic. Eaves gutter joints that absorb expansion and contraction of eaves gutters are known. Further, as another eaves gutter joint, as described in JP-B-55-42787, JP-B-61-13622, JP-B-2-141020, JP-B-61-13622, the eaves gutter joint is described. An eaves gutter joint in which a strip-shaped sealing material such as a soft foam sheet, an elastic water blocking material, and a sealing material is provided on the inner surface of the joint portion in the width direction is known.

[Problems to be solved by the device]

 However, if the eaves gutter is connected with a bellows joint that has a bellows part between the central part or the left eaves gutter joint and the right eaves gutter joint, it will be good for a while, but after a long period of time, the eaves gutter will expand and contract. There is a problem that the bellows gradually cracks during the repetition and rainwater leaks from the cracks.

Further, the eaves trough joint having the band-shaped sealing material at the joint has a complicated structure in order to prevent the band-shaped sealing material from moving on the inner surface of the eaves trough joint, and thus is difficult to manufacture. Also, when eaves troughs are connected with this eaves trough joint, and after many years have passed, expansion and contraction due to temperature differences in summer and winter are repeated, the band-shaped sealing material wears, and the eaves trough ear and the eaves trough joint ear holding part. There is a problem that the looseness of the mating with and the leakage of rainwater from the boundary between the sealing material and the eaves gutter. Therefore, the purpose of the present invention is to construct a simple eaves trough that can be easily connected to the eaves trough, and the eaves trough connected with this eaves trough joint is dependent on the temperature difference between summer and winter. It is an object of the present invention to provide an eaves trough joint that does not meander or damage the eaves trough even after repeated expansion and contraction, and does not leak rainwater even after many years have passed.

Press the inner surface of the joint of the joint body against the outer peripheral surface of the end of the eaves gutter to fit the ears of the eaves gutter to the ear holding part, and then release the release sheet protruding from both side edges of the joint body. Pull to remove. Then, since the release sheet on the surface disappears, the adhesive foam sealing material of the eaves joint is adhered to the outer peripheral surface of the eaves joint to connect the eaves trough with the eaves joint.

In this way, when the release sheet projects from both side edges of the joint body and the middle portion is divided at the central portion of the joint body, the adhesive foam sealing material is not touched by hand, and accordingly, Can be installed without soiling hands. When the eaves gutter is bonded with the eaves gutter joint of the present invention in this way, the outer peripheral surface of the eaves gutter is in a state of crushing the adhesive foam seal material provided in a strip shape on the inner surface of the joint body. Even if there are some irregularities on the outer peripheral surface of the gutter, the elasticity of the adhesive foam sealing material makes close contact with the outer peripheral surface of the eaves gutter, and this portion becomes watertight. Further, since this adhesive foam sealing material adheres to the outer peripheral surface of the eaves gutter, even if the eaves gutter moves due to the temperature difference in the summer and winter, the adhesive foam sealing material will only deform without peeling off. The water-tightness of the adhesive foam sealing material can be maintained, and rainwater will not leak even after many years have passed. In the present invention, when an adhesive foam seal material having excellent weather resistance, for example, an acrylic adhesive foam seal material is used, the elasticity does not deteriorate and the adhesiveness does not deteriorate even after long-term use. .
