Description

[Detailed description of the invention] The present invention has eave gutter connection plate parts 3 and 4 extending from both ends of the bellows plate part 2 which is freely expandable in the axial direction of the eave gutter joint body 1, and the expansion and contraction adjustment plate 5 is made of a soft material. The eaves gutter connection plates 3 and 4 are integrally formed with
A protruding rib 6 is provided on the upper surface of the eave gutter connecting plate parts 3, 4 on the boundary line between the eaves gutter connecting plate part 2 and the bellows plate part 2 in the circumferential direction over the entire width of the eave gutter connecting plate part 3, 4, and the eave gutter joint body 1 This expansion/contraction adjusting plate 5 is arranged on the inner circumference of the eaves gutter, and one of the eaves gutter connecting plate parts 3 is fixed to the eaves gutter joint body 1. To provide an eaves gutter joint that can absorb expansion and contraction due to temperature changes and prevents a bellows plate part from being crushed by the end of the eaves gutter.

The present invention will be explained in detail below using examples.

The expansion/contraction adjustment plate 5 is integrally formed of a soft material such as soft polyvinyl chloride, and is formed by extending the eave gutter connection plate parts 3 and 4 from both ends of the bellows plate part 2 having a corrugated cross section.

As shown in FIG. 5, on both sides of the eaves gutter connecting plate parts 3 and 4, extension pieces 9 having approximately the same length as the outer circumferential length of the ear part 8 are provided to extend the eaves gutter 7. The width of the connecting plate parts 3 and 4 is wider than the width of the bellows plate part 2.

Further, a protruding rib 6 as shown in FIG. 6 is projected on the upper surface of the eaves gutter connecting plate parts 3, 4 at the boundary between the eaves gutter connecting plate parts 3, 4 and the bellows plate part 2.

This expansion/contraction adjustment plate 5 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 part 3 is placed at the end of the eaves gutter joint body 1 in the inner circumferential direction. By pasting them together, an eaves gutter joint is formed, and the other eaves gutter connecting plate part 4 that is not attached to the eaves gutter joint body 1 can be moved by the expansion and contraction of the bellows plate part 2.

Then, adhesive is applied to the soil surface of the eaves gutter connecting plate parts 3 and 4, and then the ends of one row of eaves gutter 7 are fitted into the inner periphery of the eaves gutter joint body 1 from both ends, respectively, and the eaves gutter is connected to the eaves gutter. Both eaves gutters 7,
7 are connected as shown in FIG.

When the end of the eaves gutter 7 is inserted into the eaves gutter joint body 1, the end of the eaves gutter 7 is locked to the protruding rib 6 to determine the position in depth, and the eave gutter 7 Connection plate parts 3, 4
The extending piece 9 is located on the outer periphery of the ear part 8 of the eaves gutter 7 as shown in FIG. It is possible to prevent the adhesive applied to parts 3 and 4 from overflowing and flowing into the back side of the bellows plate part 2.
is not glued to the eaves gutter joint body 1.

. Now, if eaves gutter 7 expands due to a change in outside temperature, the fourth
As shown in the figure, when the bellows plate part 2 contracts, the eaves gutter connecting plate part 4 moves within the eaves gutter joint body 1 and absorbs the elongation of the eaves gutter 7. Similarly, when the eaves gutter 7 contracts, the eaves gutter connecting plate part 4 moves within the eaves gutter joint body 1 and absorbs the elongation of the eaves gutter 7. This contraction will be absorbed by elongation.

As mentioned above, in the present invention, the eave gutter connecting plate portion is extended to both ends of the bellows plate portion that is expandable and contractible in the axial direction of the eaves gutter body to form an expansion/contraction adjustment plate, so that the eave gutter connection Even if the eaves gutter connected to the plate part expands and contracts due to changes in outside temperature, this expansion and contraction is absorbed by the expansion and contraction of the bellows plate part, and it is possible to prevent the eaves gutter from deforming due to expansion and contraction. The expansion/contraction adjustment plate is made of a soft material with the eave gutter connecting plate extending from both ends of the bellows plate and is integrally formed with the eave gutter connection plate. Therefore, the expansion/contraction adjustment plate can be easily attached to the eave gutter joint body to adjust the eaves. It is possible to obtain an eave gutter joint that absorbs expansion and contraction of the gutter.

In addition, a protruding rib is provided on the upper surface of the eaves gutter connecting plate on the boundary line between the eaves gutter connecting plate and the bellows plate, so that it protrudes in the circumferential direction over the entire width of the eaves gutter connecting plate. The end of the button is positioned on the protruding rib, and the end of the eaves gutter is inserted onto the bellows plate.This prevents the bellows plate from being crushed by the eaves gutter, and the protruding rib allows the eaves gutter connection plate to be inserted into the eaves gutter connecting plate. It is also possible to prevent the adhesive applied on the top from reaching the bellows plate part, so that the expansion and contraction of the bellows plate part is not hindered, and the expansion and contraction due to the outside temperature of the eaves gutter can be absorbed without any hindrance.
