According to this invention, the strength against torsion of the eaves gutter joint can be increased. Furthermore, since the flat plate portion is difficult to see from the front, even if sink marks occur on the outer surface of the flat plate portion, the appearance of the eaves gutter joint can be maintained from the front.

Further, in the eaves gutter joint described above, the connecting bottom plate, the first connecting side plate, and the second connecting side plate are arranged above the connecting bottom plate and between the first connecting side plate and the second connecting side plate. A holding portion may be provided that sandwiches the pair of eaves gutters together with at least one of the two connecting side plates.
According to this invention, at least one of the connection bottom plate, the first connection side plate, and the second connection side plate and the holding portion can reliably hold the pair of eaves gutters so as to sandwich them. Further, since the eaves gutter is held so as to be sandwiched, even when the pair of gutter side plates of the eaves gutter are deformed so as to close in the width direction, the eaves gutter can be held close to the shape before deformation.

According to the eaves gutter joint of the present invention, even an eaves gutter deformed so as to open can be held close to the shape before deformation.

The eaves gutter support 80 is made of an elastically deformable material such as resin. The base end portion of the eaves gutter support 80 can be elastically deformed as indicated by a two-dot chain line L0. Thereby, the eaves gutter 10 can be moved so that the eaves gutter 10 approaches the fascia board 92.例文帳に追加

Assume that a building 90 to which the gutter structure 1 configured as described above is to be constructed is formed in a U-shape with a gable roof and an open bottom in a plan view, as shown in FIG. 8, for example. That is, the building 90 includes a main ridge 96 extending in a predetermined direction, and a first connecting ridge 97 and a second connecting ridge 98 extending in the same direction perpendicular to the main ridge 96 . The first connecting ridge 97 and the second connecting ridge 98 are spaced apart from each other in the direction in which the main ridge 96 extends.

When newly constructing the gutter structure 1 in the building 90, the gutter structure 1 may be constructed in order along the axial direction of the eaves gutter 10 in the same manner as the conventional construction method. In order to change the direction in which the pair of eaves gutters 10 connected to each other extend, a bend 85 that is a known joint is used.
Even when constructing a new gutter structure 1, when constructing an eaves gutter joint 30 (hereinafter also referred to as an eaves gutter joint 30A) sandwiched between connecting buildings 97 and 98, the following is required. carry out the process. In the following, the eaves gutter 10 connected by the eaves gutter joint 30A without the bend 85 will be referred to as the eaves gutter 10A, and the eaves gutter 10 connected by the eaves gutter joint 30A through the bend 85 will be referred to as the eaves gutter 10. It is called gutter 10B.
Between the pair of eaves gutters 10A shown in FIG. 8, there is formed only a gap corresponding to the axial length of the connecting member 34 of the eaves gutter joint 30A.

An adhesive is applied to ranges R1 at the ends of the pair of eaves gutters 10A indicated by two-dot chain lines L1 in FIG. The adhesive is applied to the outer surface of the eaves gutter 10A.
As shown in FIG. 9, by elastically deforming the eaves gutter 10B and the eaves gutter support 80 in advance before attaching the eaves gutter joint 30A, the gap between the pair of eaves gutter 10A can be removed. The length in the axial direction X of the entire pair of holding portions 35 of the gutter joint 30A is expanded.
The ends of the pair of eaves gutters 10A connected by the eaves gutter joint 30A are elastically deformed as indicated by the chain double-dashed line L2 in FIG. Specifically, the length in the width direction Y between the upper end of the first gutter side plate 12 and the upper end of the second gutter side plate 13 is the distance between the second locking piece 47 of the eaves gutter joint 30A and the second connecting side plate 33. The eaves gutter 10A is deformed so that the length in the width direction Y is less than the length.
As indicated by a two-dot chain line L2 in FIG. 6, the eaves gutter joint 30A is attached from below the deformed pair of eaves gutter 10A. At this time, since the gap between the pair of eaves gutter 10A is longer than the length of the entire pair of holding portions 35 in the axial direction X, the pair of holding portions 35 passes between the pair of eaves gutter 10A. The deformed pair of eaves gutters 10A and the connecting bottom plate 31, first connecting side plate 32, and second connecting side plate 33 of the eaves gutter joint 30A are connected with an adhesive.

By restoring the elastically deformed eaves gutter 10B and the eaves gutter support 80 to their original shapes, the connecting bottom plate 31, the first connecting side plate 32, the second connecting side plate 33, and the holding portion 35 Insert the ends of the pair of eaves gutters 10A into. The adhesive applied to the eaves gutter 10</b>A enters between the connecting bottom plate 31 , the first connecting side plate 32 , the second connecting side plate 33 and the holding portion 35 . At this time, the eaves gutter 10A is abutted against the linear member 74, and the gap between the pair of eaves gutter 10A is made about the length of the connecting member 34 of the eaves gutter joint 30A in the axial direction X.
When the adhesive is cured, the pair of eaves gutters 10A are connected by eaves gutter joints 30A.

On the other hand, when repairing the gutter structure 1, for example, the following steps are performed. For example, as shown in FIG. 10, a damaged part D1 is formed in the eaves gutter 10A near the eaves gutter joint 30A, and the part of the eaves gutter 10A in which the damaged part D1 is formed will be replaced.
A cutting portion D2 is formed in each eaves gutter 10A to cut each eaves gutter 10A. At this time, a damaged portion D1 is formed in the eaves gutter 10C, which is a portion of the eaves gutter 10A on the side of the eaves gutter joint 30A, and a cut portion D2 is formed so that the pair of eaves gutter 10C is connected to the eaves gutter joint 30A. to form
As shown in FIG. 11, the eaves gutter joint 30A and the pair of eaves gutter joints 10C are removed, and the eaves gutter 10 and the eaves gutter joint 30 are cut to a predetermined length. is connected to the eaves gutter 10D.

It surrounds the side plate 12 and the second gutter side plate 13 from the outside. At this time, since the connecting members 34 are connected to the first connecting side plate 32 and the second connecting side plate 33, respectively, the opening of the first connecting side plate 32 and the second connecting side plate 33 in the width direction Y is suppressed.
Therefore, even if the eaves gutter 10 is deformed to open, the first gutter side plate 12 and the second gutter side plate 13 of the eaves gutter 10 are connected by the connecting member 34 to the first connecting side plate 32 and the second connecting side plate 33. By sandwiching in the width direction Y, the eaves gutter 10 can be held close to the shape before deformation.

The connecting member 34 is arranged at the central portion in the axial direction X of each of the connecting bottom plate 31 , the first connecting side plate 32 , and the second connecting side plate 33 . As a result, the pair of eaves gutters 10 can be connected substantially symmetrically to both ends in the axial direction X of the eaves gutter joint 30 .
The upper end of the first connecting side plate 32 is arranged above the upper end of the second connecting side plate 33 , and the connecting member 34 is connected to the upper end of the first connecting side plate 32 . When the eaves gutter 10 is deformed to open in the width direction Y, for example, when the connecting side plates 32 and 33 rotate around the lower ends, the amount of deformation of the upper end of the first connecting side plate 32 is different from that of the eaves gutter joint 30. Relatively large compared to parts. Since the connecting member 34 is connected to the upper end portion of the first connecting side plate 32, deformation of the upper end portion of the first connecting side plate 32 so as to open in the width direction Y can be effectively suppressed.

In general, the first connecting side plate 32 of the eaves gutter joint 30 is arranged outside the building or the like to which the eaves gutter joint 30 is constructed. The first connecting piece 60 of the connecting member 34 extends from the second connecting side plate 33 along the connecting bottom plate 31, so that when the eaves gutter joint 30 is constructed in the building 90, it is arranged above the first connecting piece 60. It is possible to suppress other members such as the edge of the eaves 91 and the like from interfering with the first connecting piece 60 .
A first gap S<b>1 is formed between the first connecting side plate 32 and the connecting member 34 . Since the eaves gutter joint 30 is formed by injection molding, the appearance of the first connection side plate 32 can be improved by suppressing the occurrence of sink marks on the outer surface of the portion of the first connection side plate 32 facing the first gap S1. can.

A first gap S<b>1 is formed between the second side wall portion 40 and the connecting member 34 , and the connecting member 34 is connected to the flat plate portion 39 . Therefore, the strength against torsion of the eaves gutter joint 30 can be increased. Furthermore, since the flat plate portion 39 is difficult to see from the front (outside facing the first connecting side plate 32), even if sink marks occur on the outer surface of the flat plate portion 39, the appearance of the eaves gutter joint 30 from the front can be maintained. can.
The eaves gutter joint 30 has a holding portion 35 . Thereby, at least one of the connection bottom plate 31, the first connection side plate 32, and the second connection side plate 33 and the holding portion 35 can reliably hold the pair of eaves gutters 10 between them. In addition, since the eaves gutter 10 is held by the connection bottom plate 31, the first connection side plate 32, the second connection side plate 33, and the holding portion 35, the gutter side plates 12 and 13 of the eaves gutter 10 are closed in the width direction Y. Even in the case of such deformation, the eaves gutter 10 can be maintained close to the shape before deformation.

As described above, one embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and the configuration can be changed, combined, or deleted without departing from the scope of the present invention. etc. are also included.
For example, in the above embodiment, the first connecting side plate 32 may not have the stepped portion 32a.
The eaves gutter joint 30 may not include the holding portion 35 . The first gap S<b>1 and the second gap S<b>2 may not be formed in the eaves gutter joint 30 .
