である。[Detailed Description of the Invention] The present invention relates to a pipe connection structure, and more particularly to a pipe connection structure that allows a flexible pipe body and a rigid pipe body to be connected with the same diameter.

弾性変形させて密封性を得るものである。 BACKGROUND ART Conventionally, when a flexible pipe such as a vinyl hose and a rigid pipe such as a steel pipe are interconnected, a method as shown in FIGS. 1 and 2 is used. When the diameter (inner diameter) of the flexible first tube 1 is approximately the same as or slightly smaller than the outer diameter of the second tube 2, the first tube 1 is connected to the second tube 2. By fitting the first tube body 1 outwardly and tightening it with a band 3, a part of the first tube body 1 is elastically deformed to obtain sealing performance.

流体通路６が発生し易くなるおそれがある。 Therefore, if the fluid sent through the tubes 1 and 2 as shown by the arrows in FIG. 1 is powder such as cement, water, or air containing microscopic particles, , deposits 5 are formed on the stepped portion 4 formed at the tip of the second tube 2, thereby interfering with the flow path. In addition, when tightening the first tubular body 1 using the band 3, a part of the first tubular body 1 may be deformed due to uneven tightening force as shown in the example in FIG. , there is a possibility that the fluid passage 6, which causes a fluid leakage accident, is likely to occur.

グ材を充填したものである。 The present invention was developed based on these backgrounds, and aims to prevent the occurrence of accumulation by making the joints of the pipes the same diameter, and to connect the pipes with less leakage. A ring-shaped fastener is fitted onto the outer surface of a first tubular body having flexibility to restrain expansion of the diameter, and a second tubular body having a large diameter is attached to the outer surface of a second tubular body having rigidity that butts against the first tubular body. A tube is extended to surround a part of the first tube, and a caulking material is filled between the auxiliary tube and the first tube to increase the rigidity of the first tube.

れる。 3 and 4 showing an embodiment of the present invention, a first pipe body 11 having flexibility such as a hard or soft vinyl chloride corrugated pipe, and a rigid pipe body 11 such as a steel pipe. The structure is such that the first tube body 11 is connected to the second tube body 12 with their tip surfaces butted against each other, and a ring is provided on the outer surface of the tip portion of the first tube body 11 to restrain the expansion of the diameter. A shaped fastener 13 is fitted onto the outside. In the examples of FIGS. 3 and 4, the fastener 13 is an asbestos string tightly wound using the corrugations on the outer surface of the first tube body 11, and other strings, tapes, threads, etc. It is also possible to use wire or the like. A flange member 14 is integrally provided on the outer circumferential surface of the distal end of the second tubular body 12 at a position slightly shifted rearward from the distal end surface.
The first auxiliary pipe 15 with a larger diameter than the second one is in abutting state.
It extends concentrically so as to cover a part of the tube body 11 of.

密封した構造となつている。 Further, a caulking material 16 such as putty is filled between the first pipe body 11 and the auxiliary pipe 15,
Further, an adhesive (for example, a silicone rubber adhesive) is filled to close the opening between the first tube 11 and the tip of the auxiliary tube 15, thereby sealing the caulking material 16.

になる。 Therefore, both pipe bodies 11 in a butt-connected state,
When fluid is passed through the tube 12, since the connecting portion is straight, it goes without saying that fluid resistance can be reduced, but the pressure of the fluid causes the diameter of the first tube 11 to expand. Even if a leakage phenomenon from the seam 18 is to occur, it can be effectively prevented. That is,
If the first tube body 11 with low rigidity attempts to expand in diameter, it will be blocked by the fasteners 13, and if partial expansion occurs between the fasteners 13, the caulking material 16 filled with Due to its non-flowability, deformation is suppressed due to large resistance. On the other hand, if fluid tries to leak from the joint 18, the caulking material 16
This is suppressed by its own sealing ability and resistance to displacement between the caulking material 16 and the irregularities on the surface of the first tube 11 and the fastener 13.
