Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a corrugated pipe connecting stopper, particularly a corrugated pipe used for connecting a corrugated pipe having spiral irregularities on its surface to a drainage basin, a gutter, or the like. It relates to the stopper for connection.

[Conventional technology]

Conventionally, when connecting a corrugated pipe of this kind to a drainage basin, a gutter, or the like, a hole to which the corrugated pipe is to be fitted is formed in the side wall of the drainage basin, the gutter, or the like, and the end of the corrugated pipe is inserted into this hole. It was fixed by fitting.

However, it is extremely difficult to accurately bore a hole that matches the diameter of the corrugated pipe in the side wall of the drainage basin or gutter made of concrete that is relatively thick-walled. The corrugated pipe was fitted into a slightly larger hole, and a filling material such as mortar or caulking material was filled in the gap formed around the perimeter of the corrugated pipe so that the corrugated pipe would not come off. Not only that, but when they were backfilled with soil or concrete, they had a harmful effect such as dropping into drainage basins and gutters.

[Problems to be solved by the invention]

Therefore, a corrugated pipe connector as used in Japanese Utility Model Publication No. 61-12464 and Japanese Utility Model Publication No. 2-18157 has come to be used. However, due to molding by injection molding or blow molding. However, it was not economical and it was not always satisfactory from the viewpoint of workability.

The present invention was devised to solve the above-mentioned drawbacks of the conventional products, and an object thereof is to provide a stopper for connecting a corrugated pipe which is excellent in workability and economy.

[Means for solving problems]

The present invention has been devised in view of the above, and in order to fit a corrugated tube having spiral irregularities in a substantially central portion of a plate body, the corrugated tube has a mountain diameter larger than an outer diameter C of a valley portion of the corrugated tube. A circular hole having a diameter A smaller than the outer diameter D of the portion,
The inner circumference is along the circumference of the circular hole so as to be continuous with the circular hole, and the outer circumference is concentric with the circular hole and has a diameter B which is larger than the outer diameter D of the mountain portion of the corrugated pipe and has a circumference of 3 /Four
Consists of × π × B or less It is a stopper for connecting a corrugated pipe, characterized in that a fitting hole consisting of a notch hole is bored.

In addition, a projecting piece formed by cutting and raising a part of a plate is provided on the outer periphery of the cutout hole, and in the present invention, the peripheral length of the cutout hole is 3/4 × π × The reason why it is set to B or less lies in that the fitting to the corrugated pipe can be performed smoothly and the rattling after the fitting is prevented.

〔Example〕

1 is a front view showing an embodiment of a corrugated pipe connecting stopper of the present invention, and FIG. 2 is a sectional view taken along the line AA 'of FIG. FIGS. 3, 3 and 4 are explanatory diagrams of the same connection adapter and corrugated pipe, in which 1 is a flat plate made of galvanized iron plate, tin plate or synthetic resin plate, and 2 is spiral. It is a fitting hole formed in a substantially central portion of the plate body 1 for fitting the corrugated tube 3 having irregularities, and is larger than the outer diameter C of the valley portion a of the corrugated tube 3 to be fitted. A circular hole c having a diameter A smaller than the outer diameter D of the mountain portion b of the pipe 3, and an inner circumference along the circumference of the circular hole c so as to connect to the circular hole c and an outer circumference of the circular hole c. It has a diameter B which is concentric with c and is larger than the outer diameter D of the crest portion b of the corrugated tube 3 and has a circumference of 3 / 4 × π × B or less And the notch hole d, and 4 is the notch hole d.
Is a projecting piece formed on the outer periphery of the plate, and is formed by making several cuts radially running in the plate body 1 in the portion where the cutout holes d are formed and cutting and raising this. .

[Effect of device]

As is apparent from the above, the corrugated pipe connecting stopper of the present invention has an outer diameter C of the valley portion a of the corrugated pipe 3 so that the corrugated pipe 3 having spiral irregularities can be fitted in the substantially central portion of the plate 1. A circular hole c having a diameter A that is larger and smaller than the outer diameter D of the mountain portion b of the corrugated pipe 3, and the inner circumference is along the circumference of the circular hole c so as to be continuous with the circular hole c, and the outer circumference is circular. It has a diameter B which is concentric with the hole c and is larger than the outer diameter D of the crest portion b of the corrugated tube 3 and has a circumference of 3/4 × π ×.
Consists of B or less Since it has a construction in which a fitting hole 2 consisting of a notch hole d is bored, it is bored in the side wall 5 such as a drainage basin or a side groove during use as shown in FIGS. 5 and 6. The corrugated tube 3 is fitted into the hole 6, and the fitting hole 2 of the plate 1 is brought into contact with the end of the corrugated tube 3 protruding inward from the side wall 5 to rotate the plate 1 to fit the fitting hole. The peripheral edge of the corrugated pipe 2 is fastened and fixed while being fitted in the valley portion a of the corrugated pipe 3, and more specifically, a fin-shaped mountain formed at the end portion along with the cutting of the corrugated pipe 3 having spiral irregularities. The circular hole c of the fitting hole 2 so that the remaining portion e of the portion b is located in the cutout hole d.
Is a valley portion a formed at the end of the corrugated pipe 3 due to the cutting of the corrugated pipe 3.
By fitting the remaining portion f of the corrugated tube 3 and rotating the plate body 1 using the remaining portion f as a guide, the notch hole d is fitted into the remaining portion e of the mountain portion b of the corrugated pipe 3 to form the spiral valley portion a. While being guided, the projecting piece 4 is tightened and fixed by being attached to the mountain portion b.

As described above, since the corrugated pipe connecting stopper of the present invention is fixed by abutting and turning on the end of the corrugated pipe mounted on the side wall of the drainage basin or the side groove, the construction is simple and There is no inflow of earth and sand or concrete due to backfilling, and the plate is firmly screwed to the valley of the corrugated pipe while the projecting piece is attached to the ridge of the corrugated pipe. It is something that can be done.
