れる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved gutter joint provided at an outer corner of an eaves of a house. 2. Description of the Related Art As a conventional curved gutter joint provided at a protruding corner of an eave, there is, for example, one described in Japanese Utility Model Publication No. 61-41886. [0003] This curved gutter joint has a joint body which is formed in a substantially L-shaped planar shape and has eave gutter fitting portions at both ends capable of fitting an eave gutter. However, it is cut out in a square shape that can accommodate the tip of a corner tree at the eaves of a house, and is erected on the periphery of the cutout, and an arc-shaped wall that bulges toward the protruding corner side of the joint body. It is formed with. [0004] However, in such a conventional curved gutter joint, a bent portion having an angle close to a right angle is provided on both sides of the corner of the joint body. Therefore, when the eaves gutter fitted to the eaves gutter fitting section expands as the temperature rises, compressive force acts on the joint body, and the eaves gutter fitted to the eaves gutter fitting section In any case where a tensile force acts on the joint body due to the shrinkage of the joint body as the temperature decreases, the stress generated at the corner of the joint body concentrates on the bent parts on both sides of the corner. However, there is a problem that a crack is generated or broken from the bent portion. Accordingly, an object of the present invention is to provide a bent gutter joint which does not cause cracks or breakage due to a temperature change, focusing on the above problems. In order to achieve the above object, a curved gutter joint according to the present invention is formed in a substantially L-shaped planar shape, and an eave gutter fitting portion capable of fitting an eave gutter. A curved gutter joint having an arc-shaped wall bulging to the outside corner of the joint body, the joint body having a joint body provided at both ends. Both sides of the corner,
Inner corner portion and eaves gutter fitting portion and the inside corner so as to smoothly and continuously
It was formed by an arc-shaped wall swelling on the part side . In the present invention, the shape of the arc-shaped wall is not limited to a shape obtained by extracting a part of the circumference of a perfect circle, but may be a shape obtained by extracting a part of the circumference such as an infinite circle or an ellipse. According to the curved gutter joint of the present invention, when the eaves gutter fitted to the eaves gutter fitting portion expands with an increase in temperature, a compressive force acts on the joint body, and When the eaves gutter fitted to the gutter fitting part shrinks as the air temperature decreases and a tensile force is applied to the joint body, the stress generated at the corner of the joint body at the corner of the joint body is reduced from the corner to both sides from the corner. The parts are almost evenly distributed over the part. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the construction of a curved gutter joint according to an embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing a curved gutter joint of the present embodiment. FIG. 2 is a plan view showing the curved gutter joint of the present embodiment. The curved gutter joint M of the present embodiment is made of a synthetic resin (for example, hard vinyl chloride). It is formed of resin, acrylic resin, synthetic resin such as polyethylene, FRP, polycarbonate, engineering plastic such as polyphenylene sulfide or AES resin, or a composite (laminated body) of these synthetic resins. The bent gutter joint M has a substantially L-shaped planar shape and a substantially groove-shaped cross-sectional shape, and has eave gutter fitting portions 11 at both ends capable of fitting eave gutters. And a gutter gutter retaining piece 2 provided on the inner surface of the eave gutter fitting portion 11 and an eave gutter retainer piece 3 provided on the upper end of the eave gutter fitting portion 11. ing. The joint body 1, the eaves gutter engaging piece 2, and the eaves gutter holding piece 3 are all integrally formed. The joint body 1 has an entry corner 12 formed by an arc-shaped wall bulging toward the exit corner 13 of the joint body 1, and both side portions 14 of the entry corner 12 are provided with an entry corner. Corner 1
The eaves gutter fitting portion 11 is formed of an arc-shaped wall that smoothly continues. Incidentally, the arc-shaped portions 14 on both sides 14 of the corner portion 12 are formed.
Wall, the center of the arc is provided inside of the joint body 1 inside corner
Part bulges 12 side, the arc diameter R1, internal corner portion 12
(For example, the corner 12 is formed of an arc-shaped wall having a diameter of 30 mm, and both side portions 14 of the corner 12 are arc-shaped having a diameter of 20 mm). Formed by the wall). Next, the operation of the embodiment will be described with reference to FIGS. FIGS. 3 and 4 are plan views showing the construction of the bent gutter joint of the present embodiment.
Is provided at an eaves corner of a house, and one eaves gutter fitting portion 11 is fitted with an end of an eaves gutter N provided on one side of the eaves gutter, and the other eaves gutter is fitted. The joint portion 11 is fitted to the end of the eaves gutter N provided on the opposite side of the eaves protruding corner. The inner surface of each eave gutter fitting portion 11 and the outer surface of the end of the eave gutter N are adhered with an adhesive. Further, each eaves gutter N is attached to the nose shield H by a fixture not shown. In the curved gutter joint M shown in FIG. 3, the eaves gutter N fitted to the eaves gutter fitting portion 11 of the joint main body 1 expands as the temperature rises, and a compressive force is applied to the joint main body 1. This shows the shape when F1 acts. That is, the joint body 1
The entry corner 12 and the exit corner 13 are deformed from the shape at the time of construction indicated by the dashed line to the shape extruded outward. On the other hand, in the curved gutter joint M shown in FIG. 4, the eaves gutter N fitted to the eaves gutter fitting portion 11 of the joint main body 1 contracts due to a decrease in air temperature, and a tensile force is applied to the joint main body 1. The shape when F2 acts is shown. That is, the joint body 1
The shape at the time of construction shown by the two-dot chain line is deformed into a shape in which the inside corner 12 and the outside corner 13 are drawn to the house side. Incidentally, since the entry corner 12 of the joint body 1 is formed by an arc-shaped wall bulging toward the exit corner 13, the gap between the joint body 1 and the nose shield H is reduced. Corner 1
The space between 2 and the corner of the nose shield H is wider than the other portions. Therefore, as shown in FIG. 4, even if the joint body 1 is deformed due to the shrinkage of the eaves gutter N, the corner 1 of the joint body 1 is deformed.
2 does not interfere with the protruding corner of the fascia H and does not break it. Further, the entry corner 12 of the joint body 1 is
In addition to being formed by an arc-shaped wall bulging to the three sides, both sides 14 of the corner 12 of the joint body 1
Inside corner and 2 and eaves gutter fitting portion 11 so as to smoothly continuous
The joint main body 1 is formed by the elongate and shrinkage of the eaves gutter N as described above, since the eaves gutter N is formed by the arc-shaped wall bulging toward the part.
The stress generated on the side of the corner 12 is almost evenly distributed to the portion from the corner 12 to both sides 14 thereof. That is, in the curved gutter joint of the present embodiment, even if the eaves gutter N fitted to the eaves gutter fitting portion 11 expands and contracts due to a temperature change, the corner portion of the joint main body 1 is formed. No crack or breakage occurs on the 12th side. Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Are also included in the present invention. For example, in the embodiment, the curved main gutter joint has a substantially groove-shaped cross-sectional shape, but the joint main body may have a substantially semicircular cross-sectional shape. As described above, in the curved gutter joint of the present invention, the entry corner of the joint body is formed by an arc-shaped wall bulging toward the exit corner of the joint body. Not only that, the both sides of the fitting corner of the joint body were formed with arc-shaped walls that bulged to the fitting corner so that the fitting corner and the eave gutter fitting section smoothly continued. For this reason, even if the eaves gutter fitted to the eaves gutter fitting portion expands and contracts, stress concentration does not occur on the corner portion side of the joint body, and an effect that cracks and breakage do not occur is obtained.
