Description

[Detailed explanation of the invention] [Industrial application field] This invention is suitable for corrugated pipe connections, especially for roads,
This product relates to a corrugated pipe connector for connecting corrugated pipes to sewage basins, gutters, etc. in rice fields, etc.

[Conventional technology]

When connecting a corrugated pipe to a sewage tank, side gutter, etc., drill a hole that matches the diameter of the corrugated pipe in the side wall of the sewage tank or side gutter, and fit the end of the corrugated pipe into the drilled hole. It is constructed in this way,
It is extremely difficult to accurately drill such holes in the side walls of cesspits, side gutters, etc. made of relatively thick concrete. The end of the corrugated pipe is fitted into the hole, and the gap created around the hole is filled with a filler such as concrete bond or caulking agent to make it watertight, resulting in poor watertightness and complicated construction. I was getting used to it.

[Problem that the invention attempts to solve]

This invention was devised to eliminate the drawbacks of the conventional products described above, and is intended to provide a corrugated pipe connector that is excellent in workability and watertightness.

[Means to solve the problem]

This idea was devised in view of the above, and includes a flange attached to one end of a tube with threads carved into the peripheral wall, and an air hole or a filler such as caulking agent installed in the flange. A flange is provided at one end of a short tube consisting of a joint body with a small hole for injection and a screw carved into the peripheral wall surface to be screwed into the above-mentioned thread, and a caulking agent is applied to the flange. The other end of the tube protrudes from the end of the short tube, and the gap between the flanges is widened by the rotation of the short tube. The problem was solved by screwing the adapter onto the joint body to make it variable.

〔Example〕

An embodiment of this invention shown in the drawings will be described below. Fig. 1 is a perspective view showing an embodiment of the corrugated pipe connector of this invention, and A in the figure is the joint body, which is threaded onto the peripheral wall surface. Pipe body 2 formed by carving strips 1
A flange 3 is stretched over one end, and an air hole 4 or a small hole 8 for injecting a filler such as caulking agent is bored in the flange 3, and B is an adapter; A flange 7 is attached to one end of a short tube 6 formed by carving a screw 5 on the wall surface to be screwed into the thread 1, and a small hole 8 for injection of a filler such as a caulking agent is provided in the flange 7. The joint body A and the adapter B have an air hole 4 formed therein, and the other end of the tube body 2 protrudes from the end of the short tube 6, and the spacing between the flanges 3 and 7 is such that They are screwed together so that they can be changed freely by rotating the short tube 6.

The joint body A and the adapter B are integrally molded by blow molding or injection molding using synthetic resin such as polyvinyl chloride or polyethylene.

[Effect of idea]

As is clear from the above, the corrugated pipe connector of this invention has a flange 3 stretched over one end of a tube body 2 with a thread 1 carved on the peripheral wall surface, and an air hole in the flange 3. 4 or a joint body A having a small hole 8 for injecting a filler such as a caulking agent, and one end of a short pipe 6 having a screw 5 carved into the peripheral wall surface to be screwed into the thread 1. The other end of the tube body 2 is a short tube 6. The adapter B is screwed onto the joint body A so that it protrudes from the end of the pipe and the spacing between the flanges 3 and 7 is variable by the rotation of the short pipe 6. As shown in Fig. 8 and Fig. 4, the pipe body 2 is inserted into the hole C' so that the collar 3 comes into contact with the inner wall surface of the side wall C of a sewage basin, side gutter, etc., and the joint body is attached to the side wall C. An adapter B is screwed onto the tube body 2 of A so that the flange 7 comes into contact with the outer wall surface of the side wall C, and the side wall C is sandwiched between both the flange parts 3 and 7. Next, a filler E such as a caulking agent is injected through the small injection hole 8 of the flanges 3 and 7, and the hole formed between the flanges 3 and 7 is filled.
After filling the remaining gap of C' and fixing it, the corrugated pipe D is screwed onto the pipe body 2 protruding from the end of the short pipe 6 to connect it.

Therefore, in the corrugated pipe connector of this invention, the remaining gap of the hole C' drilled in the side wall C of the sewage basin, side gutter, etc. is shielded by the flanges 3 and 7 of the joint body A and the adapter B. Furthermore, a filler E such as a caulking agent is injected into the above-mentioned remaining gap through the small injection hole 8 of the flange 3 or 7, and the corrugated pipe D is inserted into the pipe body 1 of the joint body A which is fixed together. Since it is screwed on, watertightness is further improved compared to conventional products, and since these are done by screwing and injection, workability is also improved.
