[Structure] A connection structure for an eaves trough sandwiched by an upper joint B having a wide eaves trough to be connected and a lower joint C having a narrow width.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connection structure for eaves gutters, and more particularly to a connection structure for eaves gutters in which the connection ends of eaves gutters that are to be connected are fixed by sandwiching the upper and lower joints from above and below. is there.

[0002]

[Prior Art]

 Conventionally, as a connection structure of this kind of eaves gutter, as seen in Japanese Utility Model Publication No. 54-178226, etc., the inside of a joint body in which the outer peripheral surface and the inner peripheral surface of the eaves gutter to be connected are substantially the same It is generally used that the connection end of the eaves gutter is fitted into and fixed to the insertion claw provided at the substantially central portion of the peripheral surface.

However, the connection structure of these eaves gutters is formed to have substantially the same size as the outer peripheral surface of the eaves gutter in which the inner peripheral surface of the joint main body is connected so as to have a water blocking effect. However, since the connection work is performed at a high place by hanging a ladder or the like, the work of fitting the end of the eaves gutter into the insertion claw is extremely complicated.

Therefore, as seen in Japanese Utility Model Laid-Open No. 62-103926 and the like, an upper joint having an inner peripheral surface and an outer peripheral surface of the eaves gutter which are connected to each other are substantially the same, and an outer peripheral surface of the eaves gutter and A connection structure for eaves gutters has been used in which the connection end of the eaves gutter is sandwiched by a lower joint having substantially the same circumferential surface.

[0005]

[Problems to be solved by the device]

 However, since the lower joint of the eaves gutter joint is formed to have the same width or wider width as the upper joint in the above eaves gutter connection structure, the lower joint is greatly exposed to the eaves side after mounting, which is aesthetically pleasing. It was significantly reduced.

The present invention was devised to eliminate the above-mentioned drawbacks of the conventional products, and it is an object of the present invention to provide a connection structure for eaves gutters that does not deteriorate the aesthetic appearance after attachment.

[0007]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and includes an upper joint having substantially the same inner peripheral surface and outer peripheral surface of an eaves trough to be connected, and a lower joint having substantially the same outer peripheral surface and inner peripheral surface of the eaves trough. In the eaves gutter connection structure in which the connection end of the eaves gutter is sandwiched between the side joint and the eaves gutter, the upper joint is formed to be wide and the lower joint is formed to be narrow. It is a connection structure of eaves gutter.

In the connection structure of the eaves gutter of the present invention, the upper joint is formed wide so that the lower joint has a narrow width, and the wall thickness of the eaves gutter is connected to approximately the center of the outer peripheral surface of the upper joint. A ridge having the same thickness is provided around the width direction, and a dovetail-shaped fitting groove that is fitted around the inner peripheral surface of the lower joint and fits with the protruding piece is provided around the ridge. ing.

When connecting the eaves gutter, the inner peripheral surface of the eaves gutter should be brought into contact with the upper joint formed by applying an adhesive to the outer peripheral surface so that the end of the eaves gutter is abutted against the ridge. Then, the lower joint is brought into contact with the outer peripheral surface of the eaves gutter connected to the lower joint, and the projection piece is fitted into the fitting groove of the projection and fixed integrally.

[0010]

[Action]

 The connection structure of the eaves trough of the present invention is composed of an upper joint having substantially the same inner and outer peripheral surfaces of the eaves trough to be connected, and a lower joint having substantially the same outer and inner peripheral surfaces of the eaves trough. In the connection structure of the eaves gutter in which the connection ends of the eaves gutter are sandwiched, the eaves gutter is formed with a joint because the upper joint is formed wide and the lower joint is formed narrow. Even if they are connected, the connection part of the eaves gutter is inconspicuous.

【Example】

 Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings. FIG. 1 is an exploded partial perspective view showing an embodiment of a connection structure of an eaves gutter of the present invention, and FIG. Is shown.

In the figure, A is an eaves gutter that is a connecting splicer, and the lower half of both side walls 2 of the eaves gutter body 1 having a U-shaped cross section made of a synthetic resin such as polyvinyl chloride is used. The bottom plate 3 is provided with a hollow portion 4 along the longitudinal direction, and the both side walls 2 are provided with hollow edges at the upper ends thereof.

In the figure, B is a wide upper joint which is abutted against the inner peripheral surface of the eaves trough A, and is an upper joint having the inner peripheral surface and the outer peripheral surface of the eaves trough A substantially the same. At the center of the outer peripheral surface of the joint body 5 with respect to the axial direction, a ridge 6 having a rectangular cross section having a thickness and a thickness substantially equal to that of the eaves gutter A is circumferentially provided and the ridge 6 has a dovetail groove shape. The fitting groove 7 is provided.

In the figure, C is a lower joint that is abutted against the outer peripheral surface of the eaves gutter A, and the outer peripheral surface and the inner peripheral surface of the eaves trough A are substantially the same, and the upper joint is The lower joint body 8 has a width of about 1/2 to 1/4 of the width of B, and a projection 9 fitted to the fitting groove 7 is provided on the inner peripheral surface of the lower joint body 8. ..

The eaves trough A, the upper joint B, and the lower joint C are brought into contact with the inner peripheral surface of the connection end of the eaves trough A, which is to be connected to the upper joint B formed by applying an adhesive to the outer peripheral surfaces thereof. The end portion is attached to the ridge 6, and then the lower joint C having the inner peripheral surface coated with an adhesive is brought into contact with the outer peripheral surface of the connecting end portion of the eaves trough A, similarly to the upper joint B. The projecting piece 9 is fitted in the fitting groove 7 of the projection 6 and is integrally fixed.

[Effect of the device]

 As is clear from the above, the connection structure of the eaves gutter of the present invention is an upper joint having an inner peripheral surface and an outer peripheral surface of the eaves gutter which are connected to each other, and an outer peripheral surface and an inner peripheral surface of the eaves gutter are substantially the same. In the connection structure of the eaves gutter in which the connection end of the eaves gutter is sandwiched between the lower side joint and the lower side joint, the upper side joint is formed wide and the lower side joint is formed narrower. Since the upper joint is formed in a wide width, the water blocking effect on the inner surface of the connection part is large.Therefore, even if the lower joint is formed in a narrow width, there is no water leakage. Since the connection is inconspicuous because it is formed in a narrow width, the esthetic appearance of the eaves is further improved.
