Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a synthetic resin eaves gutter joint, particularly a synthetic resin eaves gutter capable of absorbing expansion and contraction of the eaves gutter due to changes in temperature for a long period of time. It relates to a joint.

[Conventional technology]

Conventionally, as this kind of synthetic resin eaves gutter joint, a double wall-shaped eaves gutter connection part is provided by providing a pressing piece along the circumferential direction to fit the end part of the eaves gutter to be connected to one end. Synthetic resin eaves gutter which slidably abuts on the inner peripheral surface of the other end of the joint body having the other end of the joint member having an eaves gutter connection at one end via a seal member running in the width direction. Joints are generally used (for example, Japanese Utility Model Laid-Open No. 64-23525).

[Problems to be solved by the device]

However, since the above-mentioned synthetic resin eaves gutter joint uses an adhesive when connecting eaves gutters, excess adhesive crosses over the pressing piece and flows out to the other end side of the joint member that is a sliding member. The member is fixed on the joint body with an excess adhesive, and as a result, the desired expansion and contraction function is deteriorated.

[Means for solving the problem]

The present invention was devised to eliminate the drawbacks of the conventional products described above, and provided a pressing piece along the width direction to insert the end of the eaves gutter to be connected to one end to form a double wall shape. The inner end surface of the other end of the joint body having the eaves gutter connection portion is slidably abutted with the other end of the joint member having the eaves gutter connection portion at one end via a seal material along the width direction. In such a synthetic resin eaves trough joint, the problem is solved by engraving a concave groove along the circumferential direction on the eaves trough joint inner peripheral surface side of the pressing piece of the joint body.

〔Example〕

The present invention has been devised in view of the above, and includes the following:
The present invention will be described in more detail with reference to the embodiments shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the synthetic resin eaves gutter joint of the present invention, FIG. 2 is a sectional view of the same, and FIG. 3 is a partially enlarged sectional view of the same.

In the figure, reference numeral A is a joint body, and a pressing piece 1 along the circumferential direction for fitting an end of an eaves gutter C to be connected to one end thereof.
To form a double-walled eaves gutter connection portion 2 and engrave a groove 3 along the circumferential direction on the eaves gutter joint inner peripheral surface side of the pressing piece 1 of the joint body A. Is.

Reference numeral B denotes a joint member that is superposed with a seal member 4 along the width direction so that the other end slidably contacts the inner peripheral surface of the other end of the joint body A, and similar to the joint body A. The eaves gutter connection 5 is formed at one end.

Reference numeral 6 is an adhesive for connecting the eaves gutter C, and 7 is an eaves gutter edge fitting portion formed on both sides of one end of the joint body A and the joint member B.

[Effect of device]

As is clear from the above, since the synthetic resin eaves gutter joint of the present invention has a concave groove formed on the eaves gutter joint inner peripheral surface side of the pressing piece of the joint body along the circumferential direction, When the eaves gutter is inserted, the excess adhesive that flows out to the joint member side flows into the concave groove formed in the pressing piece and is prevented from flowing out to the joint member side. This is effective in preventing the expansion / contraction function from being deteriorated by the adhesive.
