本発明は、コンクリート桝、ボックスカルバート等のコ
ンクリート製品と管との止水性に優れた接合部の構造に
関する。DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Industrial Field of Application) The present invention relates to a structure of a joint part between a concrete product such as a concrete pit or a box culvert and a pipe, which has excellent water-stopping properties.
（従来の技術）

タル１６を充填していた。(Prior Art) FIG. 3 is a schematic cross-sectional view showing the structure of a conventional joint between a concrete product and a pipe. As shown in the figure, one step 14 is formed around the hole 13 of the concrete pit 11, the pipe 12 is fitted into this, and the outer peripheral surface of the pipe 12 and the step 14 are connected to each other.
The groove formed by this was filled with packing 15 and mortar 16.

等沈下を起こした場合、接合部のコンクリート製品ある
いは管にクラック等の損傷を生じ止水性が失われていた
。(Problem to be solved by the invention) In such conventional structures, the joints are filled with mortar to provide rigidity, so if the concrete product and the pipe settle unevenly, the joints will be damaged. Damage such as cracks occurred in the concrete products or pipes, resulting in a loss of water-tightness.

るコンクリート製品と管の接合部の構造である。(Means for Solving the Problems) The present invention provides a two-stage stepped portion around a hole formed in a concrete product joint, a pipe is fitted into the inner stepped portion, and a pipe is fitted into the outer stepped portion. This is a structure of a joint between a concrete product and a pipe, characterized in that a groove formed by the outer peripheral surface of the concrete product and the pipe is filled with a packing having an X-shaped cross section.
パツキンは、ブチルゴム、シリコン、塩化ビニルコンパ
ウンド等の弾性体である。The packing is an elastic material such as butyl rubber, silicone, or vinyl chloride compound.
（作用）
本発明構造においては１モルタルを用いないために接合
部がフレキシブルであり、コンクリート製品と管とが不
等沈下を起こした場合でも接合部が折れ曲がるだけで損
傷を受けない。(Function) In the structure of the present invention, since no mortar is used, the joint is flexible, and even if uneven settlement occurs between the concrete product and the pipe, the joint will only bend and will not be damaged.
止水性に関しては、例えば第２図に示すごとく。Regarding water-stopping properties, for example, as shown in Fig. 2.

を防ぐ。When water pressure is applied from the outside as shown by arrow A, force acts to open the arms 6a and 6b of the gasket 6 as shown by arrow B, and the arms 6a and 6b of the gasket 6 are pressed against the outer peripheral surface of the tube 2 and the stepped portion 5, thereby preventing water from entering. can. Conversely, when water pressure is applied from the inside, the arms 6c and 6d of the gasket 6 work in the same way to prevent water from flowing out.
