Description

[Detailed explanation of the idea] The present invention relates to a gutter expansion and contraction device.

Since elongated eaves gutters made of synthetic resin such as hard vinyl chloride resin expand and contract significantly due to changes in temperature, it has been necessary to provide a gutter expansion/contraction device between the ends of the eaves gutters to absorb the expansion and contraction of the eaves gutters.

However, in the conventional gutter expansion and contraction device, since the drooping parts of the cover plate, which has drooping parts at both ends, are inserted into the eaves gutter, the cover plate may be blown away by the wind.

Furthermore, it is time-consuming to adhere one hanging part of the cover plate to the water-stop wall at the end of one eaves gutter, and this work is particularly difficult at high places such as the eaves of a roof.

The present invention solves the above-mentioned conventional drawbacks and provides a gutter expansion/contraction device which can be easily assembled and whose cover plate will not be blown away by the wind.

The gist of the present invention is that two eaves gutters each having a water-stop wall at their ends are spaced apart so that the water-stop walls face each other, and a hanging portion is provided at both ends. A cover plate is installed above the end of the eaves gutter, the drooping parts of the cover plate are inserted into the eaves gutter, and a bottom plate is attached to the lower surface of the cover plate through a hanging connecting plate, A gutter expansion and contraction device is provided in which the bottom plate is inserted into a bottom plate insertion hole provided at the lower end of the hanging connecting plate between the connecting plate and the bottom plate, and the end of the bottom plate is positioned below the bottom of the eaves gutter. Exists.

An example of the present invention will be described below with reference to the drawings.

The eaves gutters 1, 1 have a substantially rectangular groove shape in cross section, and have ears 2 on both side edges.
, 2 are provided.

Water-stop walls 3, 3 are provided at the ends of the eaves gutters 1, 1,
Eaves gutters 1.1 are attached to the eaves of the roof at intervals so that the water-stop walls 3.3 face each other.

The interval between the water-stop walls 3, 3 is set in advance to a size such that the water-stop walls 3, 3 do not come into contact with each other even if the eaves gutters 1, 1 are extended to the maximum extent.

The cover plate 4 is shaped like a relatively shallow square groove that opens upward, and is provided with hanging parts 5, 5 at both ends.

A hanging connecting plate 7 is protruded from the back surface of the cover plate 4, and a narrow groove-shaped bottom plate insertion hole 10 is formed at the lower end of the hanging connecting plate 4.

A bottom plate 8 is inserted into the bottom plate insertion hole 10 of the hanging connecting plate 7, and the end of the bottom plate 8 is located below the bottom of the eaves gutters 1,1.

To assemble this gutter expansion and contraction device, proceed as follows.

First, eaves gutters 1 are installed at intervals at the eaves of the roof.
, 1 is installed from above, and the hanging parts 5.5 are inserted into the eaves gutters 1, 1, respectively.

Next, the bottom plate 8 is inserted into the bottom plate insertion hole 10 of the hanging connecting plate 7, and the end of the bottom plate 8 is positioned below the bottom of the eaves gutters 1,1.

The end of the bottom plate 8 may or may not be in contact with the bottom of the eaves gutters 1,1.

Even if this gutter expansion/contraction device is fanned by the wind, the bottom plate 8
The cover plate 4 is not scattered because it is locked to the bottom of the cover plate.

Since the gutter expansion and contraction device of the present invention has the above structure, it can be easily assembled without the need to glue the hanging part of the cover plate to the water stop wall of the eaves gutter, and can absorb the expansion and contraction of the eaves gutter. This allows the bottom plate to lock onto the bottom of the eaves gutter and prevent the covering plate from flying away even when the wind blows.
