Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides eave gutter trailing plate parts 4 and 5 for attaching an eave gutter 3 to both ends of a bellows plate part 2 that is expandable and contractible in the direction of the gutter of an eave gutter joint body 1 with an adhesive. is extended to form an expansion/contraction adjustment plate 6, and the expansion/contraction adjustment plate 6 is arranged on the inner periphery of the eave gutter joint body 1, and one eave gutter connection plate part 4 is formed.
is fixed to the eave gutter joint body 1, and the other eave gutter connecting plate part 5
The eaves gutter joint is characterized in that a non-adhesive material 7 that is not bonded with an adhesive is interposed between the eaves gutter joint body 1 and the eaves gutter joint body 1.The purpose of this joint is to control the expansion and contraction of the eaves gutter. To provide an eaves gutter joint which can absorb water and is free from the risk of a bellows plate part being stuck to the eaves gutter joint body with an adhesive for sticking the eaves gutter.

The present invention will be explained in detail below with reference to Examples.

The expansion/contraction adjustment plate 6 is integrally formed of a material such as soft polyvinyl chloride, and is formed by extending the eave gutter connection plate parts 4 and 5 from both ends of the bellows plate part 2 having a corrugated cross section. This expansion/contraction adjustment plate 6 is arranged inside the eaves gutter joint body 1 made of a hard material such as hard polyvinyl chloride, and the lower surface of one eaves gutter connecting plate 4 is attached to the end of the inner circumferential surface of the eaves gutter joint body 1. By pasting them together, an eaves gutter joint is formed, and the other eaves gutter connecting slope portion 5 that is not adhered to the eaves gutter joint body 1 can be moved as the bellows slope portion 2 expands and contracts. Further, a non-adhesive material 7 made of polyethylene is integrally formed on the lower surface of the other eave gutter connecting plate portion 5 and the lower surface of the bellows plate portion 2, as shown in FIG. This non-adhesive material 7 may be formed only on the lower surface of the eave gutter connecting plate portion 6 as shown in FIG. However, the eaves gutter connection plate part 3
, 4. Apply an adhesive that does not adhere to polyethylene, such as a water-soluble emulsion type synthetic rubber latex adhesive or vinyl chloride adhesive, to the upper surface of 4, and then attach the ends of the pair of eaves gutters 3 from both ends. By attaching the ends of the eaves gutter 3 to the upper surfaces of the eaves gutter connection plates 4 and 5 by attaching them to the inner periphery of the eaves gutter joint body 1, both the eaves gutter 3 and 3 are connected as shown in Fig. 2. It is something that connects. Here, the adhesive is applied to the eaves gutter connection plate parts 4 and 5.
Even if it flows to the lower surface of the expansion/contraction adjustment plate 6, the eave gutter connection zero plate part 5 and the bellows plate part 2 will not be bonded to the eave gutter joint body 1 by the polyethylene non-adhesive material 7. Furthermore, the non-adhesive material 7 such as polyethylene may be formed on the inner circumferential surface of the eaves gutter joint body 1 as shown in FIG. It will become firmly attached to the main body 1. Furthermore, instead of polyethylene, a non-adhesive material 7 such as silicone may be formed at the locations shown in FIGS. 4, 5, and 6, or silicone liquid may be applied to these locations. be. Now, when the eaves gutter 3 expands due to a change in the outside temperature, the eave gutter connecting plate 5 moves within the eaves gutter joint body 1 due to the contraction of the bellows plate portion 2, as shown in Fig. 3, and the eaves gutter 3 expands. Similarly, when the eaves gutter 3 contracts, this contraction is absorbed by the extension of the bellows slope portion 2. As described above, in the present invention, the eave gutter connecting slope portion is extended from both ends of the bellows plate portion that is freely expandable and contractible in the axial direction of the eave gutter joint body to form the expansion/contraction adjusting plate, so that the eave gutter connecting plate Even if the eaves gutter connected to the eave gutter expands and contracts due to changes in outside temperature, this expansion and contraction is absorbed by the expansion and contraction of the bellows plate, which prevents the eaves gutter from deforming due to expansion and contraction. The continuation slope part of the eaves gutter is fixed to the eaves gutter joint body, and a non-adhesive material that is not bonded with adhesive is interposed between the other eave gutter connecting plate part and the eave gutter joint body, so the eave gutter Even if the adhesive applied on the eaves gutter connecting slope to strengthen the eaves gutter flows between the eaves gutter connecting slope and the eaves gutter joint body, there is no risk that this eaves gutter connecting slope will be glued to the eaves gutter joint body, and the eaves gutter will The gutter connecting plate part is adhesively fixed to the eaves gutter joint body, and it is possible to reliably prevent the eaves gutter from being deformed due to the inability of the eave gutter connecting plate part to move according to the expansion and contraction of the eaves gutter.
