Abstract

(57) [Summary] [Purpose] To provide a rain gutter joint in which a water-swellable seal material exerts its function sufficiently to ensure waterproofness. [Structure] A circumferential groove groove 3 is formed in the fitting connection portion 2 of the joint body 1, and a space 4 is left in the groove portion 3 to accommodate a water-swellable seal material 5. The water-swellable seal material 5 which absorbs rainwater and undergoes enormous deformation can escape to the lateral space 4 in the recessed groove portion 3, and the water-swellable seal material 5 is in the recessed groove portion 3. Therefore, it does not unnecessarily overflow and is properly adhered to the outer peripheral surface of the end part of the eaves gutter.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rain gutter joint for fitting and connecting end portions of rain gutters such as eaves gutters and down gutters.

[0002]

[Prior Art]

 Conventionally, as shown in FIGS. 5 and 6, rain gutter joints in which water swellable seal materials (b) are attached to the inner peripheral surfaces of the fitting connection portions on both sides of the joint body (a) are known. Has been. The rain gutter joint is an eaves trough joint that fits and connects the ends of the eaves gutter (ha), and is fitted to the outer periphery of the ends of the eaves gutter (ha) so that the ends of the eaves gutter (ha) are Is to be fitted and connected. In this case, the water-swellable seal material (b) absorbs rainwater and undergoes enormous deformation, sealing the gap between the inner peripheral surface of the joint body (a) and the outer peripheral surface of the end of the eaves (c). The waterproof function is demonstrated.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, the water-swellable seal material (b), which has undergone enormous deformation by absorbing rainwater, deforms the eaves gutter (c) because there is no escape area for it, and the circumferential direction At a partial location of the above, a water-swellable seal material (b) and the outer peripheral surface of the eaves gutter (c) formed a gap, and the waterproof function was not sufficiently exhibited.

The present invention was devised 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 undergoes enormous deformation deforms laterally. (EN) It is possible to provide a rain gutter joint which can be appropriately escaped and does not deform the end portion of the rain gutter, and in which a gap is hard to occur and a waterproof function is sufficiently exerted.

[0005]

[Means for Solving the Problems]

 The rain gutter joint of the present invention has a circumferential groove formed in the fitting connection portion of the joint body, and a water-swellable seal material is attached to the groove while leaving a space in the groove. With this configuration, the above problems are solved.

[0006]

[Action]

 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 seal material is attached to the groove while leaving a space in the groove. Therefore, the water-swellable seal material that absorbs rainwater and undergoes enormous deformation can escape to the lateral space in the groove, and the water-swellable seal material can be placed in the groove. Therefore, the water swellable seal material does not unnecessarily overflow, and the water swellable seal material appropriately adheres to the connection surface of the rain gutter to sufficiently exhibit the waterproof function.

[0007]

【Example】

 The rain gutter joint shown in FIGS. 1, 2 and 3 is an embodiment of the present invention, in which a circumferential groove portion 3 is formed in a fitting connection portion 2 of a joint body 1, and a space is formed in the groove portion 3. -A water-swellable seal material 5 is accommodated and attached while leaving the sheath 4.

The rain gutter joint is an eaves trough joint which is integrally injection-molded with synthetic resin, and ear engaging portions 6 each of which is bent in a substantially U shape are integrally formed on both upper edge portions thereof. Has been formed. Further, two recessed groove portions 3 are provided in parallel on the inner peripheral surface of the fitting connection portion 2 on both sides of the joint body 1, and each of the recessed groove portions 3 is biased toward the joint end side to condense water. A swellable seal material 5 is attached along the longitudinal direction of the concave groove portion 3, and a space 4 is provided on the opposite side of the concave groove portion 3 from the joint end side.

The water-swellable seal material 5 accommodated in the recessed groove portion 3 is a liquid water-swellable seal material (trade name “Chemguard U”: manufactured by Sanyo Kasei Co., Ltd.). It is formed by applying and adhering linearly.

Further, the rain gutter joint is a eaves trough joint that fits and connects the ends of the eaves gutter 7, and is fitted to the outer periphery of the ends of the eaves gutter 7 to connect the ends of both the eaves gutters 7 to each other. It is fitted and connected. In this case, the water-swellable seal material 5 absorbs rainwater and undergoes enormous deformation, sealing the gap between the inner peripheral surface of the fitting connection portion 2 of the joint body 1 and the outer peripheral surface of the eaves gutter 7. Therefore, the waterproof function is exerted.

The eaves gutter 7 is a square gutter shape and is integrally extruded from a synthetic resin, and hollow ears 8 are integrally formed on both upper edge portions thereof. A rain gutter joint is fitted on the outside between the ends of the eaves trough 7, and in this case, the two ear engaging portions 6 of the rain gutter joint are engaged with the both ears 8 of the eaves trough 7, respectively. Then, the rain gutter joint is fitted on the outside of the end of the eaves gutter 7.

Therefore, in the rain gutter joint of the embodiment, circumferential groove grooves 3 are formed in the fitting connection portions 2 on both sides of the joint body 1, and a space 4 is left in each groove portion 3. Since the water-swellable seal material 5 is attached to the water-swellable seal material 5, the water-swellable seal material 5 which absorbs rainwater and undergoes enormous deformation can escape to the lateral space 4 in the groove 3. In addition, the water-swellable seal material 5 does not unnecessarily overflow because it is in the concave groove portion 3, and the water-swellable seal material 5 is appropriately provided on the outer peripheral surface of the end portion of the eaves gutter 7. They are in close contact with each other and fully exert the waterproof function. Further, in fine weather, the water-swellable seal material 5 is in a contracted state and is brought into sliding contact with the outer peripheral surface of the eaves gutter 7, and the thermal expansion and contraction of the eaves gutter 7 is absorbed smoothly.

The rain gutter joint of the present invention may be as in the embodiment shown in FIG. That is, the rain gutter joint of the embodiment is a gutter joint, which is formed by the water-side fitting receiving tube portion 9 and the water-side fitting connection portion 2, and has a rectangular tubular trough 10 The end parts of the are connected by fitting. Further, in the rain gutter joint, the end of the water-side trough 10 is inserted and fitted in the fitting receiving tube portion 9, and the fitting connection portion 2 is inserted into the end of the water-side down gutter 10. When fitted together, the ends of both vertical gutters 10 are fitted and connected. Further, in the rain gutter joint, a single groove 3 is formed only on the outer periphery of the underwater fitting connection 2, and the water swellable seal material 5 is accommodated in the groove 3. The water-swellable seal material 5 is a water-swellable seal material (trade name "Aquaprene DX": manufactured by Sanyo Kasei Kogyo Co., Ltd.) molded in a ring shape and attached thereto. There is.
