Description

[Detailed explanation of the idea] The present invention relates to a gutter joint.

Conventional expansion joints for eaves gutters are constructed by stacking an outer joint body and an inner joint body with a waterproof material in between so that they can move in the length direction, and one end of each of the outer joint body and the inner joint body One end of the eaves gutter is glued and fixed to the area. For this reason, water leakage often occurs due to uneven adhesive application, and it is difficult to connect eaves gutters after construction because the eaves gutters need to be moved for connection, and when construction is done at high places. There was a problem in that it placed a large burden on the worker, and furthermore, due to the structure, there was a step on the outer surface, which was large and conspicuous, and spoiled the aesthetic appearance of the eaves and gutter system.

The present invention was made in view of the above-mentioned conventional problems, and the outer joint body and the inner joint body are overlapped so that they cannot move relative to each other, and the left and right eaves gutters are slidably pressed between them. As a result, we provide an eave gutter joint that can easily connect both eaves gutters after construction, has better water-stopping properties than conventional ones, and enhances the beauty of the eaves gutter system. The purpose is to

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

In Figures 1 to 3, 10 and 10 are eaves gutters,
20 is an outer joint body of the gutter joint, 30 is an inner joint body of the gutter joint, and 40 is a waterproof material (packing). As shown in FIG. 4, the outer joint body 20 has a spacer protrusion 23 extending along the inner surface from the ear portion 21 side to the other ear portion 22 side at the longitudinal center of the inner surface.
is formed. The ears 21 and 22 have a size that allows the ears 11 and 12 of the eaves gutter 10 to be inserted into them, and the edges of the ears have downward locking protrusions 21 extending in the length direction.
a, 22a are provided. The inner joint body 30 has an outer shape that approximately follows the inner shape of the eaves gutter 10, and has a fifth
As shown in the figure, one side edge 31 is attached to the outer surface near the left and right ends.
Water stop material 40 extending from the vicinity to the vicinity of the other side edge 32
grooves 33 and 34 are formed respectively, and the side edge 3
A locking piece 35 that serves as a stopper stands up at both ends of each of 1 and 32, and these four locking pieces 35
are engaged with both end surfaces of the ears 21 and 22, respectively. The water stop materials 40, 40 are adhesively fixed to the grooves 33, 34, respectively, but have a diameter larger than the groove diameter, and come into pressure contact with the eaves gutters 10, 10, respectively, when connected.

After the eaves gutter is attached to the roof, this gutter joint connects the end of the ear part 11 on one side of the eave gutter 10 and the end of the ear part 11 on the same side as the ear part 11 of the other eave gutter 10 to the outer joint body. 20, and then fit the ends of the ears 12 on the other side of the eaves gutters 10, 10 into the ears 22 on the other side of the outer joint body 20, respectively. Fit into one half side and the other half side, and finally, one side edge 3 of the inner joint body 30.
1 is inserted between the locking protrusion 21a of the ear portion 11 on one side and the ear portions 11, 11 on the one side of the eaves gutters 10, 10, and using elasticity, the side edge 32 on the other side is attached to the outer joint body. It is inserted between the locking protrusion 22a of the ear part 12 on the other side of the eave gutter 20 and the ear part 12, 12 on the other side of the eaves gutter 10,10. As a result, eaves gutter 1
The ends of 0 and 10 are the outer joint body 20 and the inner joint body 3
The spacer protrusion 23 is inserted into the gap created by the spacer protrusion 23 so that it can slide freely in the length direction. 23 and when it is shortened, it is further separated from the spacer protrusion 23, thereby absorbing the expansion and contraction of the eaves gutter. Even if the eaves gutters 10, 10 slide on the outer joint body 20 and the water stop materials 40, 40, the locking pieces 35 are engaged with both end surfaces of the ears 21, 22 of the outer joint body 20, respectively. No deviation occurs between the two joint bodies 20 and 30.

In addition, FIG. 6 shows a gutter joint for a corner eave gutter in which the present invention is implemented. In the figures, parts corresponding to those in the embodiment described above are given the same reference numerals.

As described above, according to the present invention, when connecting two eaves gutters, the outer joint body is placed on the outer surface of both eaves gutters and the ears are fitted, and the inner joint body is overlapped on the inside of both eaves gutters. Just insert the side edge into the ear part of the outer joint body,
There is no need to move the eaves gutter, so it is easy to work with, and it is easy to connect the eaves gutter after construction.As mentioned above, the eave gutter and gutter joint are connected so that they can be moved relative to each other, and no adhesive is used. There is no water leakage caused by uneven application of adhesive, and water-stopping performance is improved compared to conventional products.Furthermore, since the outer joint body and inner joint body do not move relative to each other, the appearance remains unchanged, and the overall length is short and compact. Since it is less noticeable, it has the advantage of increasing the beauty of the eaves and gutter system compared to conventional methods.
