という問題点がある。2) Since the string-like water-expandable rubber is attached to an arbitrary position by adhesive, the ends are overlapped and the attachment position cannot be specified, so the attachment position may be moved slightly depending on the operator. There is a problem that uniformity cannot be measured.

There is a problem with this.

In the joint structure of the formed propulsion fume pipe, a recess is formed in the circumferential direction on one side of the joint collar, a curled part is formed at the end to be buried in concrete during molding, and the end edge on the insertion port side is formed. is bent slightly outward, a convex portion is formed on one side of the propulsion fume tube corresponding to the recessed portion, and a convex portion is formed in the spigot portion that is inclined downward from the insertion port side toward the tube axis direction. A first recess and a second recess are formed inside the recess, a first rubber ring is arranged in the first recess, and a second rubber ring is arranged in the second recess. ing.

You may.

する方法がとられている。Next, the integrity of the collar and the propulsion fume tube is most advantageous near the embedded tip of the collar. However, the material of the collar is generally steel, and although the shorter the embedded length, the more economical it becomes, if it is too short, the position of the anchor reinforcing bar, that is, the position of the curled part, becomes a disadvantageous position in terms of integrity. Therefore, as a method of minimizing the length of the embedded portion of the embedded collar while maintaining the integrity of the curled portion and the propulsion fume tube, a method has been adopted in which the tip of the embedded collar is curled.

１）従来のような継手カラーとアンカー鉄筋との溶接が
不要となり、製造が簡略化できる。その結果、継手カラ
ーは高価な材料にすることが可能である。[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. 1) There is no need to weld the joint collar and anchor reinforcing bars as in the past, simplifying manufacturing. As a result, the fitting collar can be made of expensive material.
【００３６】２）水膨張ゴムの取り付けを端末のカール

、本来の止水機能を発揮できる。2) By attaching the water-expandable rubber to the curled portion or concave portion of the end, it becomes possible to use an integrated water-expandable rubber ring, eliminating the need for overlapping joints as in the past and improving water-stopping properties. can be improved. Further, since the curled portion is attached by the elastic repulsive force of the water-expandable rubber, no adhesive is required. Even if a break occurs between the joint collar and the inflatable rubber, the adhesive will not cover the surface of the inflatable rubber, so water will be supplied to the inflatable rubber and it will be able to perform its original water-stopping function.
【００３７】３）継手カラーの端末をカール状に形成さ

、「めくれ」を防止するために端末を直角状に折り曲げ

より、これらの問題点は解消できる。3) Since the end of the joint collar is formed into a curled shape, it is more resistant to "turning up" than conventional types. Another method is to bend the terminal at right angles to prevent it from curling up, but in this case, changes in the material and variations in material thickness tend to occur. Problems can be resolved.
【００３８】４）継手カラーの挿入側端縁を外方に屈曲

カラーでも容易に接合が可能となる。4) Since the insertion side edge of the joint collar is bent outward and formed into a trumpet shape, it is possible to easily join even joint collars made of thin material.

るため、前記問題点は解決される。5) Since the first recess is formed on the insertion port side of the spigot portion and is inclined downward toward the back,
Conventionally, the structure is such that the entrance side is lowered. Furthermore, when adhesive is applied to the insertion part of the rubber ring, the adhesive acts as a lubricant when the rubber ring is bonded before it hardens, causing the rubber ring to slip and making it difficult to insert. Since the gradient direction of the portion is reversed, the above problem is solved.

に、製造を効率よく行うことができる。6) When manufacturing a Hume tube, the inclined part of the insertion side edge is pressed by the upper mold, and the curled part at the tip of the collar is formed by using the outer shape of the concave part plus the thickness of the joint collar as a fulcrum. Since the collar is pressed into close contact with the frame, mortar can be prevented from entering the entire collar, eliminating the need for post-treatment of the collar and allowing for efficient manufacturing.
