Description

[Detailed Description of the Invention] The present invention relates to an improvement in the structure for connecting the ends of a pair of eaves gutters.

Conventionally, when connecting eaves gutters by absorbing the expansion and contraction that occurs in eaves gutters, eaves gutter joints with a special structure are constructed by incorporating members that absorb expansion and contraction into ordinary joints formed in a roughly U-shape. Since the eaves and gutter joints are connected using , the structure of the eaves and gutter joints is complicated and manufacturing costs are high.

The present invention has been made in view of the above points, and the purpose of the present invention is to provide a connection structure for eaves gutters that can absorb the expansion and contraction that occurs in eaves gutters by using ordinary joints. It is in.

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

The joint 1 is made of hard synthetic resin and is molded into a roughly U-shape with an open top, and an ear holder 2 with a roughly C-shaped cross section is integrally molded at the upper end of the pipe. The ends of the pair of eaves gutters 3 are slidably placed on the inner surface of the joint body 1 by slidably fitting the ears 4 at both upper ends into the ear receivers 2.

The connecting plate 5 is formed into a shape in which mounting pieces 7 made of hard PvC extend between both ends in the expansion/contraction direction of a bellows material 6 having a width approximately equal to the length in the circumferential direction of the joint 1, and each mounting piece 7 is It has a U-shape that is curved at approximately the same curvature as the inner surface of the joint 1.

The eaves gutters 3 are connected to the joint 1 using the connecting plate 5. First, a pair of eaves gutters 3 are installed on both halves of the inner surface of the joint 1.
At the same time, the ears 4 are slidably fitted into the ear receivers 2, and the bellows material 6 is placed in the gap between the ends of both eaves gutters 3, 3, and each of the ends is attached. The pieces 7, 7 are respectively fixed to the inner surface of the end of each eaves gutter 3 with adhesive 8, and both eaves gutter 3, 3
are connected on joint 1.

That is, both eaves gutters 3, 3 are supported at their ends on the joint 1 and are telescopically connected by the connecting plate 5, so that the expansion and contraction of the eaves gutters 3 in the longitudinal direction is absorbed on the joint 1.

As described above, in the present invention, both eaves gutters are telescopically connected on the joint by a connecting plate that is separate from the joint, so special processing is required for the joint as in the past. There is no need to apply this, and ordinary joints can be used as they are.

In addition, if an adhesive layer is provided on the back side of the mounting piece 7 in advance,
Eaves and gutters can be easily connected.

In the connecting plate, 6 is a bellows material, and 7 is a mounting piece.

Claims (1)

[Scope of utility model registration request] The ends of a pair of eaves gutters each having a roughly U-shaped cross section are placed on both halves of the inner surface of the joint, which is shaped like a U-shape with an opening at the top, so that the eaves gutters can slide freely in the longitudinal direction. The ears at the upper end of each eaves gutter are slidably fitted into the ear receivers provided at the upper end of the joint, and the mounting pieces are shaped to extend from both ends of the bellows material in the direction of expansion and contraction. A connecting plate separate from the above-mentioned joint is placed on the inner surface of the pair of eaves gutters on the inner surface of the joint, and the bellows material is positioned between the ends of the pair of eaves gutters, and each mounting piece is attached to each of the eaves gutters. A connection structure for eaves gutters that is adhesively fixed to the inner surface.
