〈産業上の利用分野〉
本発明は、水門等コンクリート或いは鉄製構造体の表面
に固定される止水ゴムパツキンの接合法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for joining water-stop rubber gaskets fixed to the surface of concrete or iron structures such as water gates.

合部分に介在させて使用するものである。<Prior art> This type of water-stop rubber gasket is formed into a long piece by extrusion molding, and a plurality of these pieces are joined to make an even longer piece.
It is used for the above-mentioned water gates, or it is used by joining both end surfaces of a single long object to form a ring shape and interposing it at the joint between large diameter concrete pipes.

る。When such water-stopping rubber gaskets are joined together to form a longer product or into a ring shape, a method is employed in which an unvulcanized rubber thin plate is sandwiched between the joint end faces, pressed, and heat-vulcanized.

力がかからず、その結果接合力が弱くなるという問題が
ある。<Problems to be Solved by the Invention> In general, this type of water-stop rubber gasket is often provided with a cavity in order to improve its reaction force characteristics. However, when a water-stop rubber gasket has a cavity, the rubber glue and unvulcanized rubber thin plate flow into the cavity during joining, and even though pressure is applied, this pressure is not applied to the joint. As a result, there is a problem that the bonding force becomes weak.

法では長尺物には不適であり、また環状物には通用でき
ないこと、後者の方法では、接合部が中実になってしま
い、反力特性が極端に低下する等の問題がある。Conventional methods to deal with this problem include inserting an iron rod from one end of a water-stop rubber seal into the cavity of the joint to eliminate a place for the unvulcanized rubber to escape, or joining with the cavity of the joint part crushed. However, the former method is unsuitable for long objects and cannot be used for circular objects, and the latter method results in solid joints and poor reaction force characteristics. There are problems such as an extreme drop in performance.

記２つの止水ゴムパツキンを加硫接合するものである。Means for Solving Problems〉 The method for joining water-stop rubber gaskets according to the present invention is to apply a rubber-based glue to each end surface of the water-stop rubber gasket to be joined, and then apply rubber glue to each end surface of the water-stop rubber gasket to have substantially the same shape as the end surface of the water-stop rubber gasket. A thin plate of unvulcanized rubber is sandwiched between the end faces of the two water-stop rubber gaskets, and a vulcanized rubber pipe that matches the shape of the cavity is inserted between the unvulcanized rubber and the thin plate of unvulcanized rubber. # Fit the hollow part of the slope into the hollow part of each of the above water stop rubber gaskets located on both sides, place the joint part in a heating mold and pressurize it, and apply the above two water stop seals through the thin rubber plate. It is used to vulcanize and bond rubber gaskets.

R), each having a cavity 2.2 with a diameter of about 13 mm. This waterproof rubber gasket 1.1
is molded by extrusion and vulcanized. The hollow portions 2, 2 function to improve the reaction force characteristics as described above. 3.3 is a joint end surface of each water-stop rubber gasket 1.1, to which CR-based rubber glue 4, 4 is applied. 5 is
An unvulcanized rubber thin plate interposed between the joint end surfaces 3, 3 of the water-stop rubber gaskets 1, 1, made of CR, has a shape slightly larger than the joint end surfaces 3, 3, and has a thickness of approximately 2H. ~5 questions. This thin rubber plate 5 is attached to the joining end surfaces 3, 3.
The reason why the shape is slightly larger than that is to increase the pressure on this thin rubber plate 5 when pressed with a mold. still,
As described above, the same effect can be obtained even if the thin rubber plate 5 is made to have substantially the same shape as the joining end surfaces 3, 3, and another thin rubber piece is interposed around the thin rubber plate 5 during mold compression. Reference numeral 6.6 indicates a pipe which is passed through the cavities 7, 7 of the unvulcanized rubber thin plate 5, and is made of CR and is vulcanized. The diameter of this vibro 6 can be about 13 mm, and the length can be about 20 to 30 mm. The vibro 6 is fitted into each cavity 2.2 of the waterproof rubber gaskets 1, 1 on both sides and pushed in until the unvulcanized rubber thin plate 5 comes into contact with the joint end surfaces 3, 3.
