そして、同図に示すごとく、溝３２内にパツキン
３３をモルタル３４で固定するか、あるいは接着
剤で接着する等していた。<<Conventional technology>> Conventionally, in order to attach a water-stop seal to a concrete product, as shown in Fig. 5, a protrusion 31 is provided on the inner surface of a single connected weir plate 30, and after concrete is poured and hardened, the formwork is removed. Then, as shown in FIG. 6, a groove 32 was formed in the concrete connecting end face.
As shown in the figure, a packing 33 is fixed in the groove 32 with mortar 34 or bonded with an adhesive.
≪発明が解決しようとする問題点≫
上述のように、従来の止水パツキンの取付け

剤による場合には運搬時や施工時にパツキンが外
れやすいという欠点があつた。≪Problems to be solved by the invention≫ As mentioned above, conventional water-stop gaskets were installed using mortar or adhesive after the concrete product was created, resulting in poor work efficiency.
Furthermore, when using mortar, the mortar needs a period of time to harden, and water tends to enter between the mortar and concrete, causing problems with its water-stopping function. When using adhesives, the seals tend to come off during transportation or construction. There were flaws.
≪発明の構成≫

ることが好ましい。≪Structure of the Invention≫ ≪Means for Solving the Problems≫ The present invention solves these problems, and as shown in FIG. This formwork for concrete products is characterized in that a protrusion 2 having a shape that fits the shape and having a groove 3 for fitting a packing 4 to the top is fixed. The protrusion has a shape that matches the shape of the end face of the concrete product, and has a ring shape surrounding a through hole in a pipe product, and a U shape in a U-shaped product. The protrusion 2 is fixed by welding through a hole 5 in the weir plate, as shown in FIG. 1, for example.
It is preferable that the cross-sectional shape of the groove 3 and the tip of the packing 4 fitted therein be a substantially quadrilateral cross-section as shown in the figure so as not to be dislodged even by the impact of concrete pouring.
≪作用≫
第１図に示すごとく、突条２の溝３にパツキン

合端面に埋設される。<<Operation>> As shown in Fig. 1, the tip of the packing 4 is fitted into the groove 3 of the protrusion 2, concrete is poured into the formwork, and after hardening, the formwork is removed from the mold, as shown in Fig. 2. As shown, the packing 4 is buried in the joint end surface of the concrete product 6.
本発明型枠によりパツキンはコンクリート製品
製造と同時に接合端面に埋設され、このようにし
て埋設されたパツキンは完全にコンクリートと一
体化するのでコンクリートから抜け落ちたりする
ことがなく、止水効果にも優れるものである。 By using the formwork of the present invention, the packing is buried in the joint end face at the same time as concrete product manufacturing, and the packing that is buried in this way is completely integrated with the concrete, so it will not fall out of the concrete and has an excellent water-stopping effect. It is something.
≪実施例≫
