The present invention relates to a connection port of a spiral corrugated pipe configured to be more elastically engaged in joining the protruding frame inside the connection port fitted to the outer surface of the spiral corrugated pipe with the spiral pipe outer surface. The main focus is on improving and making construction extremely easy.

In general, the connection port used to connect the connection of the spiral pipe should be close to the spiral pipe, and at the same time, the airtightness should be maintained so that the object conveyed through the inside of the spiral pipe does not leak to the outside.

Therefore, for the above airtightness, for example, the structures of Korean Utility Model Publication No. 85-1102, Korean Utility Model Publication No. 88-8165, and Korean Utility Model Publication No. 90-4333 have been proposed, but these are spiral pipes and fittings. Filling members such as foams or sealants are filled in between and applied or serve as an airtight protective layer.

However, the above constructions improve the airtightness, but the construction work is performed by filling the foamed material between the spiral pipe and the connection port during construction, or by applying the sealant to the outer surface of the spiral pipe and joining the connection port to the outside to maintain the airtightness. There was a troublesome fault.

In order to reduce the drawbacks of the prior art, the present application is designed to be elastically fitted to the outer concave portion of the corrugated spiral pipe to simplify the construction work and to provide a spiral pipe fitting which can be satisfied even in airtightness. Looking at the configuration in detail based on the accompanying drawings as follows.

The reference numeral 1 denotes an opening portion 2 which is formed so that one side is opened as a connection port, and a pair of binding pieces 3 provided with a metallic reinforcing plate 4 buried therein is formed from the opening portion 2 as a starting point. It is erected vertically, the binding holes 5 are drilled at regular intervals along the longitudinal direction of the binding piece 3, and the fastening members 6 are fastened corresponding to the binding holes 5.

The inner side of the connection port 1 is formed with a spiral protruding frame 9 so as to be coupled to the outer concave-convex portions 8a and 8b of the spiral tube 7 fitted inside.

That is, the inner protrusion frame 9 of the connection port 1 has a height H and a width (to which the bone corresponding to the recessed portion 8a of the screw tube 7 hereinafter referred to as "the valley of the spiral tube") can be fitted. S), and formed in the outer periphery of the protrusion frame (9) exploded concave space portion 10.

The concave space 10 is helically addressed to the outer circumferential surface of the protruding frame 9 protruding helically.

On the other hand, preferably, when used as the connection port 1, the opening part 2 is opened in the state in which the fastening member 6 is disassembled, and is fitted to the outside of the connection part to which the spiral tube 7 and the spiral tube 7 are connected.

At this time, the protruding frame 9 of the connector 1 is sandwiched between the valleys 8a of the spiral tube to fix the position thereof. Then, the connector 1 is connected by fastening the fastening member 6 to the fastening hole 5. The spiral tube 7 is tightened to the outer surface to perform a function as the connector 1.

At this time, the metallic reinforcing plate 4 buried inside the binding piece 3 is provided with a reinforcing role that maintains the binding force uniformly over the entire surface even though the distance between the fastening holes 5 is slightly longer. You can distribute evenly.

On the other hand, when fastening the connector (1) to the outer surface of the spiral tube (7) as described above, the protruding frame (9) formed somewhat higher than the bone height (Ha) of the spiral tube (7) recessed space portion 10 formed inside Is elastically in close contact with the bone of the spiral tube 6 as it is deformed by elastic force, and at the same time the left and right sides of the protruding frame 9 as the concave space portion 10 is narrowed and deformed as shown in the enlarged view of FIG. Since the surface is also in close contact with the wall surface of the valley of the spiral tube 7 to have an airtight effect over the entire surface, the airtightness is improved. Therefore, the construction work does not need to be filled with foam materials on the inner surface of the connection port as in the prior art. It is easy to improve the workability, and because the concave space portion 10 formed on the inner surface of the protruding frame 9 of the connector 1 is closely deformed while the shape of the protruding frame 9 can increase airtightness. It works.
