次に、以上の構成からなる波付管装置３、端末部材２、および波付管端部固定装置４の作用効果について説明する。波付管装置３とか波付管端部固定装置４とかにおける端末部材２は、筒状の挿入部２ａとフランジ部２ｂとを備えて、挿入部２ａが波付管１の内部に挿入され、フランジ部２ｂが波付管１の端部から突出する。そして、挿入部２ａに設けられた掛止部２ｃが、波付管１の内面凸部１ｂに掛け止まることで、端末部材２は、波付管１の端部に取り付けられる。ここで、フランジ部２ｂは、波付管装置３（つまり、端末部材２付きの波付管１）を複数、波付管１の軸方向Ｐと直交する方向に並べたときに、そのフランジ部２ｂどうしが干渉することなく波付管１が当たり合うことが可能となる大きさに形成されている。このため、複数の波付管装置３、３を、波付管１の軸方向Ｐと直交する方向に並べる際に、複数の波付管１、１を互いに近接させて配置することができる。そして、フランジ部２ｂには、通し部２ｄが形成されており、この通し部２ｄを通る固定具５により、端末部材２、ひいては波付管装置３を、型枠板７に（図示実施の形態においては、固定板６を介して型枠板７に）固定することができ、複数の波付管１、１を互いに近接させて配置固定することが可能となる。 Next, the effects of the corrugated tube device 3, the terminal member 2, and the corrugated tube end fixing device 4 configured as described above will be described. The terminal member 2 in the corrugated tube device 3 or the corrugated tube end fixing device 4 has a cylindrical insertion portion 2a and a flange portion 2b, and the insertion portion 2a is inserted into the corrugated tube 1, A flange portion 2b protrudes from the end portion of the corrugated pipe 1 . The terminal member 2 is attached to the end portion of the corrugated tube 1 by hooking the hooking portion 2c provided on the insertion portion 2a to the inner convex portion 1b of the corrugated tube 1 . Here, when a plurality of corrugated pipe devices 3 (that is, corrugated pipes 1 with terminal members 2) are arranged in a direction orthogonal to the axial direction P of the corrugated pipes 1, the flange portion 2b The corrugated pipes 1 are formed in a size that allows the corrugated tubes 1 to come into contact with each other without the 2b interfering with each other. Therefore, when arranging the plurality of corrugated tube devices 3, 3 in the direction orthogonal to the axial direction P of the corrugated tube 1, the plurality of corrugated tubes 1, 1 can be arranged close to each other. A through portion 2d is formed in the flange portion 2b, and the terminal member 2 and, in turn, the corrugated pipe device 3 are attached to the formwork plate 7 by a fixture 5 passing through the through portion 2d (in the illustrated embodiment). ) can be fixed to the formwork plate 7 via the fixing plate 6, and the plurality of corrugated pipes 1, 1 can be arranged and fixed in close proximity to each other.

また、固定板６は、フランジ部２ｂの内側の開口を閉塞する閉塞部６ｂを有している。このため、端末部材２が、コンクリート等の硬化材に埋設されて、型枠板７が除去された後には、この閉塞部６ｂを有する固定板６で、端末部材２内、ひいては波付管装置３内（つまり、端末部材２付きの波付管１内）に埃等が進入するのを防ぐことができる。 In addition, the fixed plate 6 has a closing portion 6b that closes the inner opening of the flange portion 2b. Therefore, after the terminal member 2 is embedded in a hardening material such as concrete and the formwork plate 7 is removed, the fixed plate 6 having the closed portion 6b can be used to secure the inside of the terminal member 2 and the corrugated pipe device. It is possible to prevent dust and the like from entering inside 3 (that is, inside corrugated tube 1 with terminal member 2).

また、端末部材２の挿入部２ａには、当接リブ２ｇが設けられている。当接リブ２ｇを設けることで、端末部材２に対する波付管１のガタツキを防止することができる。そして、特に、当接リブ２ｇが、波付管１の角部内面と対面する、挿入部２ａの周壁２ｊにおける変形し難い角部にあることで、波付管１と端末部材２との相対回動を的確に抑えることができ、かつ、端末部材２に対する波付管１のガタツキを効果的に防止することができる。 Further, the insertion portion 2a of the terminal member 2 is provided with a contact rib 2g. By providing the contact rib 2g, it is possible to prevent the corrugated tube 1 from rattling with respect to the terminal member 2. FIG. In particular, since the contact rib 2g is located at a corner portion of the peripheral wall 2j of the insertion portion 2a that faces the inner surface of the corner portion of the corrugated tube 1 and is difficult to deform, Rotation can be appropriately suppressed, and rattling of the corrugated tube 1 with respect to the terminal member 2 can be effectively prevented.

また、掛止部２ｃの、波付管１の軸方向Ｐにおける長さが、対応する波付管１の内面凹部１ａの前記軸方向Ｐにおける長さよりも、短く形成されている。これにより、端末部材２と波付管１との前記軸方向Ｐへの相対移動が一定範囲で許容され、その範囲で、端末部材２に対する波付管１の、前記軸方向Ｐの位置を調整することができる。 In addition, the length of the hooking portion 2c in the axial direction P of the corrugated tube 1 is formed shorter than the length of the corresponding inner surface concave portion 1a of the corrugated tube 1 in the axial direction P. As a result, relative movement in the axial direction P between the terminal member 2 and the corrugated tube 1 is permitted within a certain range, and the position of the corrugated tube 1 relative to the terminal member 2 in the axial direction P is adjusted within that range. can do.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、波付管１の外面凸部１ｄと外面凹１ｃの両方が四角形状をしていなくても、図１７～図２１に示すように、波付管１が、その外面凸部１ｄの頂面および内面凹部１ａの底面が、波付管１の軸心に直交する断面において四角形状（詳しくは、正方形等の矩形形状、図示実施例では、角部に円弧を有する角丸正方形形状）をなすように形成され、かつ、その外面凹部１ｃの底面および内面凸部１ｂの頂面が、波付管１の軸心に直交する断面において円形形状をなすように形成されてもよい。また、この波付管１に取り付けられる端末部材２にあっては、挿入部２ａは、その周壁２ｊが、波付管１の内面凸部１ｂの頂面の断面円形形状に沿った円形筒状を成すように形成される。そして、フランジ部２ｂは、その周縁が、波付管１の外面凸部１ｄの頂面の断面四角形状（詳しくは、断面正方形等の矩形形状、図示実施例では、角部に円弧を有する断面角丸正方形形状）に沿った四角形状（詳しくは、正方形等の矩形形状、図示実施例では、角部に円弧を有する角丸正方形形状）を成すように形成される。また、この端末部材２にあっては、溝状孔２ｐとか弾性片２ｎとかは設けられていない。また、この端末部材２には、波付管１の内面凸部１ｂと対面する箇所に、その波付管１の内面に当接する当接リブが設けられていないが、この当接リブ（特に、波付管１の内面を圧接する圧接リブ）を設けるようにしてもよい。こうして、波付管１の内面凸部１ｂの頂面が、断面円形形状の場合に、端末部材２に当接リブ（圧接リブ）を設けると、波付管１の内面と当接リブ（圧接リブ）との摩擦により、波付管１と端末部材２との相対回動が抑えられる。また、この当接リブに代えて、固定具５を波付管１の内面に当接（特に、波付管１の内面を圧接）するように設けることで、波付管１と端末部材２との相対回動を抑えるようにしてもよい。 It should be noted that the present invention is not limited to the above-described embodiments, and various other modifications are possible. For example, even if both the outer surface convex portion 1d and the outer surface concave portion 1c of the corrugated tube 1 do not have a square shape, the corrugated pipe 1 may have the top shape of the outer surface convex portion 1d as shown in FIGS. The surface and the bottom surface of the inner concave portion 1a have a quadrangular shape (specifically, a rectangular shape such as a square, in the illustrated embodiment, a rounded square shape having arcs at the corners) in a cross section perpendicular to the axis of the corrugated tube 1. , and the bottom surface of the outer concave portion 1c and the top surface of the inner convex portion 1b may be formed so as to form a circular shape in a cross section perpendicular to the axial center of the corrugated tube 1. In the terminal member 2 attached to the corrugated tube 1, the peripheral wall 2j of the insertion portion 2a has a circular cylindrical shape along the circular cross-sectional shape of the top surface of the inner convex portion 1b of the corrugated tube 1. is formed to form The peripheral edge of the flange portion 2b has a rectangular cross-sectional shape (specifically, a rectangular shape such as a square cross-section) of the top surface of the outer surface convex portion 1d of the corrugated tube 1. It is formed so as to form a quadrangular shape (specifically, a rectangular shape such as a square, in the illustrated embodiment, a rounded square shape having arcs at the corners) along a rounded square shape. Further, in this terminal member 2, the groove-like hole 2p and the elastic piece 2n are not provided. Further, the terminal member 2 is not provided with a contact rib that contacts the inner surface of the corrugated tube 1 at a location facing the inner surface convex portion 1b of the corrugated tube 1. , press-contact ribs for press-contacting the inner surface of the corrugated tube 1 may be provided. In this way, when the top surface of the inner convex portion 1b of the corrugated tube 1 has a circular cross-sectional shape, if the terminal member 2 is provided with a contact rib (pressure contact rib), the inner surface of the corrugated tube 1 and the contact rib (pressure contact rib) are formed. Relative rotation between the corrugated tube 1 and the terminal member 2 is suppressed by friction with the rib. In place of the abutment ribs, fixing members 5 are provided so as to abut against the inner surface of the corrugated tube 1 (especially, the inner surface of the corrugated tube 1 is pressed against the corrugated tube 1 and the terminal member 2). You may make it suppress the relative rotation with.
