BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter coupling for fitting and connecting ends of rain gutters such as eaves gutters and vertical gutters.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a water-swellable seal material (b) is provided on the inner peripheral surface of a fitting connection portion on both sides of a joint body (a). Gutter fittings are known. The rain gutter joint is an eave gutter joint for fitting and connecting the ends of the eaves gutter (c), and is fitted around the end of the eaves gutter (c) to connect the ends of both eaves gutter (c) to each other. Are fitted and connected. In this case, the water-swellable sealing material (b) absorbs rainwater and undergoes enormous deformation, and seals the gap between the inner peripheral surface of the joint body (a) and the outer peripheral surface of the end of the eaves gutter (c). , A waterproof function is exhibited.

[0003]

However, in the above-mentioned conventional technology, the water-swellable seal material (b) that has absorbed rainwater and has undergone enormous deformation has no evacuation area, and has an eaves gutter (c).
And a gap is formed between the water-swellable seal material (b) and the outer peripheral surface of the eaves gutter (c) at a partial location in the circumferential direction, and the waterproof function is fully exhibited. It was not done.

The present invention has been devised in order to solve the above-mentioned problems in the prior art. That is, the problem is that a water-swellable seal material that absorbs rainwater and deforms greatly is appropriately positioned laterally. An object of the present invention is to provide a rain gutter joint that can escape and does not deform the end of the rain gutter, and hardly generates a gap, and sufficiently exhibits a waterproof function.

[0005]

According to the gutter joint of the present invention, a circumferential groove is formed in the fitting connection portion of the joint body, and a water-swellable sealing material is accommodated in the groove, leaving a space in the groove. in such and attached shall, joint ends of the groove portion the aqueous swellable sealant
Ri Na arranged by offsetting along the section side, in which above problems have been solved by this arrangement.

[0006]

In the rain gutter joint of the present invention, a circumferential groove is formed in the fitting connection portion of the joint body, and a water-swellable sealing material is housed in the groove so as to leave a space in the groove. The water-swellable sealing material, which absorbs rainwater and undergoes enormous deformation, can escape to the side space in the groove, and
The water-swellable sealing material is in the concave groove portion and does not overflow unnecessarily, and the water-swellable sealing material appropriately adheres to the connection surface of the rain gutter to sufficiently exhibit a waterproof function. Furthermore, this

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rain gutter joint shown in FIGS. 1, 2 and 3 is an embodiment of the present invention, in which a circumferential groove 3 is formed in a fitting connection 2 of a joint body 1 and the groove is formed. leaving space 4 within 3 made of accommodates attaching a water-swellable sealing material 5, the water swelling
Of the sealing material 5 to the joint end side in the groove 3
It is arranged by placing .

The rain gutter joint is an eave gutter joint integrally formed of synthetic resin by injection molding, and ear engaging portions 6 each bent substantially in a U-shape are integrally formed on both upper edge portions thereof. Is formed. On the inner peripheral surfaces of the fitting connection portions 2 on both sides of the joint body 1, two concave grooves 3 are provided in parallel.
A water-swellable sealing material 5 is provided along the longitudinal direction of the concave groove 3 so as to be shifted toward the end of the joint.
The space 4 is provided on the side opposite to the joint end side.

The water-swellable seal material 5 housed and provided in the concave groove portion 3 is a liquid water-swellable seal material (trade name "Chemigard U" manufactured by Sanyo Chemical Industry Co., Ltd.). It is formed by linearly applying and adhering.

The rain gutter joint is an eave gutter joint for fitting and connecting the ends of the eaves gutter 7 and is fitted around the end of the eaves gutter 7 to connect the ends of the eaves gutter 7 to each other. It is to be fitted and connected. In this case, the water-swellable seal material 5 absorbs rainwater and undergoes enormous deformation, and seals the gap between the inner peripheral surface of the fitting connection 2 of the joint body 1 and the outer peripheral surface of the end of the eaves gutter 7. , A waterproof function is exhibited.

The eaves gutter 7 has a square gutter shape and is integrally extruded with a synthetic resin, and has hollow ears 8 integrally formed on both upper edges thereof. The eaves gutter 7
The gutter joint is fitted to the outside between the ends of the eaves gutter. In this case, the above-mentioned both ears engaging portions 6 of the gutter gutter are engaged with the both ears 8 of the eaves gutter 7, respectively. A rain gutter joint is fitted outside the end of the gutter 7.

Therefore, in the gutter joint of this embodiment, concave grooves 3 in the circumferential direction are respectively formed in the fitting connection portions 2 on both sides of the joint body 1, and water is left in each concave groove 3 while leaving a space 4. Since the swellable sealing material 5 is housed and attached, the water swelling sealing material 5 that absorbs rainwater and undergoes enormous deformation can escape to the side space 4 in the concave groove portion 3 and has the same water swelling property. The sealing material 5 is in the groove 3 and does not overflow unnecessarily, and the water-swellable sealing material 5 properly adheres to the outer peripheral surface of the end of the eaves gutter 7 to sufficiently exhibit a waterproof function. is there. Change
In this case, the water-swellable sealing material 5
Since it is arranged along the side of the joint end,
7 is removed from the fitting connection portion 2 of the joint body 1 by the thermal expansion and contraction.
The water that adheres to the eaves gutter 7
The swellable sealing material 5 is applied to the inner surface of the joint end side in the concave groove 3.
When stopped, the water-swellable sealing material 5 did not move,
Of the eaves gutter 7 is reliably prevented by the
Things. Also, the side opposite to the end of the joint in the groove 3
Space 4 is formed in the eaves gutter 7
The same as the side where the rainwater to be absorbed is absorbed by the water-swellable sealing material 5.
Space 4 will be located and the water-swellable seal
The material 5 can absorb rainwater without any trouble and can be deformed enormously.
You. When the weather is fine, the water-swellable sealing material 5 is in a contracted state and is in sliding contact with the outer peripheral surface of the eaves gutter 7, so that the thermal expansion and contraction of the eaves gutter 7 is smoothly absorbed.

In the rain gutter joint of the present invention, FIG.
May be as in the embodiment shown in FIG. That is, the rain gutter joint of this embodiment is a vertical gutter joint, which is formed by the fitting receiving tube part 9 on the water side and the fitting connection part 2 on the water side. The ends are fitted and connected. Further, in the rain gutter joint, the end of the water trough 10 is inserted and fitted into the fitting receiving tube portion 9, and the fitting connection 2 is inserted into the end of the water trough 10. The ends of the downspouts 10 are fitted and connected by fitting. In the rain gutter joint, the groove 3 is formed only on the outer periphery of the fitting connection 2 on the underwater side.
A water-swellable seal material 5 is housed in the concave groove portion 3 and the water-swellable seal material 5 is a water-swellable seal material (trade name: Aquaprene DX). ": Sanyo Kasei Kogyo Co., Ltd.) formed into a ring shape and attached.
