Description

[Detailed description of the invention] The present invention relates to a connection structure between a square gutter and a square gutter joint.
In detail, when a square gutter such as a gutter holder or a joint is fitted with a square gutter joint, the side walls of both sides will surely come into contact with each other without stopping, so that a good water stop condition can be obtained. and the connection structure between the square gutter joint and the square gutter joint.

Conventionally, the connection between a square gutter and a square gutter joint is a square gutter in which a square tube-shaped ear edge that protrudes outward is formed on the upper edge of both side walls, and a cross-section on the upper edge of both sides of the gutter receiver. Using a square gutter joint with a groove-shaped ear edge fitting part, press the square gutter from above to below the square gutter joint to fit the square gutter into the gutter receiving part of the square gutter joint, and This was done by fitting the edge of the gutter into the edge fitting part.

However, in the conventional connection structure between a square gutter and a square gutter joint, as shown in FIG. ，
5 is pressed downward, the side walls of the square gutter 1 buckle inward, and a gap A is created between the outer surfaces of both side walls 7, 7 of the square gutter 1 and the side walls 6, 6 of the square gutter joint 2. This caused rainwater to often leak from the gap A.

The present invention has been made to overcome the above-mentioned conventional drawbacks.

Next, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 11 designates a square gutter used in the present invention, and the upper edges of both side walls 17, 17 of the square gutter 11 are bent inward at approximately right angles to provide bent pieces 18, 18.
Rectangular tube-shaped ear edge portions 15, 15 are provided projecting upward from the tip portions 8, 18.

Reference numeral 12 designates a square gutter joint used in the present invention, and the upper edges of both side walls 16, 16 of the square gutter joint 12 are bent inward at approximately right angles to provide presser pieces 14, 14. , 14 are bent downward to provide locking pieces to form ear edge fitting parts 13, 13.

Pressing pieces 14, 14 of the ear edge fitting parts 13, 13
is the upper surface 1 of the ear edges 15, 15 of the square gutter 11.
9 and 19 are formed in such a size that they can be pressed.

The connection structure between the square gutter 11 and the square gutter joint 12 is the third
As shown in the figure, the square gutter 11 is inserted from above the square gutter joint 12, and the ear edges 15, 15 of the square gutter 11 fit inside the ear edge fitting parts 13, 13 of the square gutter joint 12. be done. In this case, the ear edges 15, 15 of the square gutter 11
The upper surfaces 19, 19 are the edge fitting portions 1 of the square gutter joint 12.
By being pressed by the lower surfaces of the holding pieces 14 and 14 of 3 and 13, stress is generated in the bending pieces 18 and 18 to bend them downward, and the side wall 1 of the square gutter 11
6 and 16 also generate stress that bends them toward the side walls 16 and 16 of the square gutter joint 12, causing the side walls 16 and 16 of the square gutter 11 to bend.
16 outer surface and bottom lower surface and side wall 1 of square gutter joint 12
The inner surfaces of 6 and 16 and the upper surface of the bottom are brought into close contact so that there is no gap between them.

The connection structure of the square gutter and square gutter joint of the present invention is configured as described above, so that when the square gutter and the square gutter joint are connected, the square tubular ears protruding inwardly and upwardly from both side walls. As a result of the upper surface of the edge being pressed by the lower surface of the holding piece of the edge fitting part of the square gutter joint, stress is generated in the side wall of the square gutter to bend it toward the side wall of the square gutter joint. The side walls of the gutter joint are in close contact with each other, and there is no gap between them, preventing rainwater from leaking.
