Description

この発明は、管内に配線・配管材を収容する、配線・配管材の保護管に関するものである。   The present invention relates to a protective tube for a wiring / piping material in which the wiring / piping material is accommodated in the tube.

従来、例えば、鉄道の線路に沿って布設されるケーブル等を収容する保護管として、図１５に示されるような保護管があった。この保護管３０は、保護管３０内にケーブル等を挿入するために、管壁３１に長手方向に連続するスリット３２が形成されるとともに、そのスリット３２に対向してヒンジ部３３が形成されていた（例えば、特許文献１参照）。ここで、長手方向に並べられた保護管３０、３０を接続するためには、二つの半円筒状の閉じ具４０、４０が用いられた。すなわち、これら閉じ具４０、４０を、両保護管３０、３０の周面に当てるようにして、互いに連結することで、両保護管３０、３０が接続された。   Conventionally, for example, there has been a protective tube as shown in FIG. 15 as a protective tube for accommodating a cable or the like laid along a railroad track. In order to insert a cable or the like into the protective tube 30, the protective tube 30 is formed with a slit 32 continuous in the longitudinal direction on the tube wall 31, and a hinge portion 33 is formed facing the slit 32. (For example, see Patent Document 1). Here, in order to connect the protective tubes 30 and 30 arranged in the longitudinal direction, two semi-cylindrical closures 40 and 40 were used. That is, the two protection tubes 30 and 30 are connected by connecting the closures 40 and 40 to each other so as to contact the peripheral surfaces of the protection tubes 30 and 30.

特開平１１−１９１９１１号公報（段落番号００２１、図１２）Japanese Patent Laid-Open No. 11-191911 (paragraph number 0021, FIG. 12)

ところで、前記従来の保護管３０においては、保護管３０、３０の接続にあたって、それら保護管３０、３０とは別に二つの閉じ具４０、４０を用意し、しかも、それら二つの閉じ具３０、３０を連結するという作業を要し、非常に面倒であった。   By the way, in the conventional protective tube 30, when the protective tubes 30, 30 are connected, two closures 40, 40 are prepared separately from the protective tubes 30, 30, and the two closures 30, 30 are prepared. It was very troublesome to connect the two.

この発明は、上記した従来の欠点を解決するためになされたものであり、その目的とするところは、保護管どうしを簡単に接続することができる、配線・配管材の保護管を提供することにある。   The present invention has been made to solve the above-described conventional drawbacks, and an object of the present invention is to provide a protective tube for wiring / piping material, in which protective tubes can be easily connected to each other. It is in.

この発明に係る配線・配管材の保護管は、前記目的を達成するために、次の構成からなる。すなわち、
請求項１に記載の発明に係る配線・配管材の保護管は、管壁に外面側に突出する外側凸部と内面側に突出する内側凸部とが長手方向に交互に連続して並んで形成された波付き部を有し、管内に配線・配管材を収容して保護する保護管本体と、その保護管本体を他の保護管本体と接続するための継手とからなる。ここで、前記保護管本体は、前記管壁に、長手方向に連続して割れた切割部を有し、その切割部の拡開により、前記配線・配管材が管内に進入可能な開口が長手方向に沿って形成され、前記配線・配管材の進入後には前記開口が閉じ得るよう変形可能である。そして、前記継手は、前記保護管本体と一体であって、前記管壁の一方の端からその長手方向に延設されるようにして筒形状に形成され、前記他の保護管本体の端部にその外周面に対向する方向から被せられて前記端部に外嵌されるように、前記切割部に連通するとともに前記筒形状の軸方向に連続する拡開可能な開放部を有する。 In order to achieve the above object, the protective pipe for wiring / piping material according to the present invention has the following configuration. That is,
In the protective tube for wiring / piping material according to the first aspect of the invention, the outer convex portion projecting to the outer surface side and the inner convex portion projecting to the inner surface side are arranged alternately and continuously in the longitudinal direction on the tube wall. It has a formed corrugated portion, and includes a protective tube main body that accommodates and protects the wiring / piping material in the tube, and a joint for connecting the protective tube main body to another protective tube main body. Here, the protective tube main body has a slit portion that is continuously cracked in the longitudinal direction on the tube wall, and the opening through which the wiring / pipe material can enter the tube is elongated by expanding the slit portion. It is formed along the direction and can be deformed so that the opening can be closed after the wiring / pipe material enters. The joint is integral with the protective tube main body, and is formed in a cylindrical shape so as to extend in the longitudinal direction from one end of the tube wall, and the end of the other protective tube main body It has an openable part that can be expanded and connected to the cut part and continuous in the axial direction of the cylinder so as to be covered from the direction facing the outer peripheral surface of the cover and to be externally fitted to the end part.

この保護管によると、保護管本体と一体となった継手が、軸方向に連続する開放部を通して、他の保護管本体の端部、すなわち継手が形成されていない側の端部に外嵌されることで、保護管本体と他の保護管本体が接続される。このため、継手を別途設ける必要もなく、保護管本体どうし、ひいては保護管どうしが簡単に接続される。しかも、順次、保護管本体における、継手が形成されていない側の端部に、次の保護管本体を、その保護管本体と一体となった継手を介して接続すれば、多数の保護管本体、ひいては多数の保護管を連続して接続することができる。そして、継手には、保護管本体の切割部に連通する開放部が形成されているため、前記切割部を拡開した開口から、管内に配線・配管材を進入させるにあたって、この継手が、管内への配線・配管材の進入を妨げることはない。したがって、継手の開放部を通して、保護管本体と他の保護管本体とを接続する際に、その接続と同時に、前記開口から、保護管本体の管内に配線・配管材を進入させることもできる。   According to this protective tube, the joint integrated with the protective tube main body is externally fitted to the end of the other protective tube main body, that is, the end on the side where the joint is not formed, through the axially continuous open portion. Thus, the protective tube main body and the other protective tube main body are connected. For this reason, it is not necessary to separately provide a joint, and the protective tube main bodies, and by extension, the protective tubes can be easily connected. In addition, if the next protective tube body is connected to the end of the protective tube body on the side where the joint is not formed via a joint integrated with the protective tube body, a large number of protective tube bodies As a result, a large number of protective tubes can be connected in succession. Since the joint is formed with an open portion that communicates with the cut portion of the protective tube main body, when the wiring / pipe material is introduced into the pipe from the opening in which the cut portion is expanded, It does not hinder the entry of wiring and piping materials to Therefore, when connecting the protective tube main body and another protective tube main body through the opening of the joint, simultaneously with the connection, the wiring / pipe material can be made to enter the pipe of the protective tube main body from the opening.

また、請求項２に記載の発明に係る配線・配管材の保護管は、請求項１に記載の保護管において、前記開放部は、少なくとも前記保護管本体側が、前記切割部よりも幅広に形成されて、その開放部の、前記保護管本体側の端縁が、前記他の保護管本体に外嵌する際の、前記他の保護管本体の端縁との位置合わせ部となっている。これにより、保護管本体の切割部よりも幅広に形成された開放部における、位置合わせ部となった保護管本体側の端縁と、他の保護管本体の端縁とを合わせることで、保護管本体と他の保護管本体とを、長手方向の所定の位置で接続することができる。   Moreover, the protective tube of the wiring / piping material according to the second aspect of the present invention is the protective tube according to the first aspect, wherein at least the protective tube main body side of the open portion is wider than the split portion. Then, the edge of the open portion on the side of the protective tube main body serves as an alignment portion with the edge of the other protective tube main body when it is externally fitted to the other protective tube main body. In this way, in the open part formed wider than the cut part of the protective tube body, the edge on the protective tube body side that became the alignment part and the edge of the other protective tube body are aligned to protect The tube main body and another protective tube main body can be connected at a predetermined position in the longitudinal direction.

また、請求項３に記載の発明に係る配線・配管材の保護管は、請求項１または２に記載の保護管において、前記開放部は、その開放部の周縁を前記他の保護管本体の外面に押し付けることにより、拡開して、前記継手内に、前記他の保護管本体が進入するような幅寸法を有している。これにより、保護管本体と一体となった継手における開放部の周縁を、他の保護管本体の外面に押し付けることで、開放部が拡開して継手内に他の保護管本体が進入するため、保護管本体どうしが、一層簡単に接続される。   Moreover, the protective tube of the wiring / piping material according to the third aspect of the present invention is the protective tube according to the first or second aspect, wherein the open portion has a peripheral edge of the open portion of the other protective tube main body. It is widened by being pressed against the outer surface, and has a width dimension such that the other protective tube main body enters the joint. As a result, by pressing the periphery of the open part of the joint integrated with the protective tube main body against the outer surface of the other protective tube main body, the open part expands and the other protective tube main body enters the joint. The protective tube bodies are more easily connected.

また、請求項４に記載の発明に係る配線・配管材の保護管は、請求項１ないし３のいずれか１項に記載の保護管において、前記継手には、前記他の保護管本体の外側凸部と嵌合するように、内面側に嵌合溝が設けられている。こうして、保護管本体と他の保護管本体との接続にあたって、保護管本体と一体となった継手の嵌合溝と、他の保護管本体の外側凸部とが嵌合することで、保護管本体どうしを長手方向に相対移動することなく確実に接続することができる。   The protective tube for wiring / piping material according to the invention described in claim 4 is the protective tube according to any one of claims 1 to 3, wherein the joint includes an outer side of the other protective tube main body. A fitting groove is provided on the inner surface side so as to be fitted with the convex portion. Thus, when connecting the protective tube main body to another protective tube main body, the fitting groove of the joint integrated with the protective tube main body is fitted with the outer convex portion of the other protective tube main body, so that the protective tube The main bodies can be reliably connected without relatively moving in the longitudinal direction.

また、請求項５に記載の発明に係る配線・配管材の保護管は、請求項１ないし４のいずれか１項に記載の保護管において、前記保護管は、弾性を備え、前記切割部および前記開放部は、その弾性力に抗するように拡開し、また、その弾性力による復帰により閉じるようになっている。   Moreover, the protective tube of the wiring / piping material according to the invention of claim 5 is the protective tube according to any one of claims 1 to 4, wherein the protective tube is provided with elasticity, and the cutting portion and The opening portion is expanded so as to resist the elastic force, and is closed by returning by the elastic force.

この発明に係る配線・配管材の保護管によれば、保護管本体と一体となった継手が、開放部を通して、他の保護管本体の端部に外嵌されることで、保護管本体と他の保護管本体が接続されるため、継手を別途設ける必要もなく、保護管どうしを簡単に接続することができる。   According to the protective tube for wiring / piping material according to the present invention, the joint integrated with the protective tube main body is externally fitted to the end of the other protective tube main body through the open portion, Since other protective tube main bodies are connected, there is no need to separately provide a joint, and the protective tubes can be easily connected.

以下、この発明に係る配線・配管材の保護管を実施するための最良の形態を図面に基づいて説明する。   The best mode for carrying out the protective pipe for wiring / piping material according to the present invention will be described below with reference to the drawings.

図１ないし図１３は、本発明の一実施の形態を示す。図中符号１は、配線・配管材（配線材または配管材）である。２は、管内に配線・配管材１を収容して保護する保護管本体である。４は、前記保護管本体２を他の保護管本体３と接続するための継手である。５は、前記保護管本体２と前記継手４とからなる保護管である。   1 to 13 show an embodiment of the present invention. Reference numeral 1 in the figure denotes wiring / piping material (wiring material or piping material). Reference numeral 2 denotes a protective tube body that houses and protects the wiring / piping material 1 in the tube. 4 is a joint for connecting the protective tube main body 2 to another protective tube main body 3. Reference numeral 5 denotes a protective tube composed of the protective tube body 2 and the joint 4.

ここで、保護管本体２は、管壁６に外面側に突出する外側凸部７ａと内面側に突出する内側凸部７ｂとが長手方向に交互に連続して並んで形成された波付き部７を有して可撓性を備えている。また、保護管本体２は、管壁６に、長手方向に連続して割れた切割部８を有している。そして、保護管本体２は、前記切割部８の拡開により、配線・配管材１が管内に進入可能な開口８ａが長手方向に沿って形成され、配線・配管材１の進入後には前記開口８ａが閉じ得るよう変形可能となっている。ここにおいて、開口８ａが閉じ得るよう変形可能とは、開口８ａが自動的に閉じる場合の他に、外力を加えることで閉じる場合も含むものである。そして、図３に示すように、管壁６に、切割部８と対峙するヒンジ部９が設けられている。このヒンジ部９は、前記波付き部７を、周方向において分断するようにして形成されている。詳細には、このヒンジ部９は、波付き部７から一体となって連続し、外面側に突出するように断面略Ｕ字形状に湾曲して形成されている。   Here, the protective tube main body 2 has a corrugated portion in which an outer convex portion 7a projecting to the outer surface side and an inner convex portion 7b projecting to the inner surface side are alternately and continuously arranged in the longitudinal direction on the tube wall 6. 7 has flexibility. Moreover, the protective tube main body 2 has a cut portion 8 that is continuously cracked in the longitudinal direction on the tube wall 6. The protective tube main body 2 has an opening 8a through which the wiring / piping material 1 can enter into the pipe along the longitudinal direction by expanding the slit portion 8, and the opening after the wiring / piping material 1 enters It can be deformed so that 8a can be closed. Here, the phrase “deformable so that the opening 8a can be closed” includes not only the case where the opening 8a is automatically closed but also the case where the opening 8a is closed by applying an external force. As shown in FIG. 3, the tube wall 6 is provided with a hinge portion 9 that faces the split portion 8. The hinge portion 9 is formed so as to divide the corrugated portion 7 in the circumferential direction. Specifically, the hinge portion 9 is integrally formed from the corrugated portion 7 and is curved to have a substantially U-shaped cross section so as to protrude outward.

また、保護管本体２の管壁６には、切割部８の両側に、開口８ａから進入する配線・配管材１を、前記開口８ａを閉じることにより掬い上げて管内に収容する掬上部１０が形成されている（図７および図８参照）。この掬上部１０は、外側凸部７ａから周方向に延設される外側突状部１０ａと、内側凸部７ｂから周方向に延設される内側突状部１０ｂとが、長手方向に交互に連続して並ぶようにして形成されている（図２および図３参照）。そして、外側突状部１０ａの外面と内側突状部１０ｂの内面との間隔Ｌ２が、外側凸部７ａの外面と内側凸部７ｂの内面との間隔Ｌ１よりも小さくなっている（図３参照）。特に、図示実施の形態においては、外側突状部１０ａの外面と内側突状部１０ｂの内面との間隔Ｌ２は、波付き部７における外側凸部７ａおよび内側凸部７ｂ側から切割部８側に向かうに連れて漸次小さくなっている。   Further, on the pipe wall 6 of the protective tube main body 2, on both sides of the cut portion 8, there are rib upper portions 10 for scooping up the wiring / piping material 1 entering from the opening 8 a by closing the opening 8 a and accommodating it in the pipe. It is formed (see FIGS. 7 and 8). The flange 10 has an outer protrusion 10a extending in the circumferential direction from the outer protrusion 7a and an inner protrusion 10b extending in the circumferential direction from the inner protrusion 7b alternately in the longitudinal direction. They are formed so as to be continuously arranged (see FIGS. 2 and 3). The distance L2 between the outer surface of the outer protrusion 10a and the inner surface of the inner protrusion 10b is smaller than the distance L1 between the outer surface of the outer protrusion 7a and the inner surface of the inner protrusion 7b (see FIG. 3). ). In particular, in the illustrated embodiment, the distance L2 between the outer surface of the outer protruding portion 10a and the inner surface of the inner protruding portion 10b is from the outer protruding portion 7a and inner protruding portion 7b side of the corrugated portion 7 to the cut portion 8 side. It gradually gets smaller as you head toward.

さらに、掬上部１０は、その掬上部１０を配線・配管材１の外面に押し付けることにより、切割部８が拡開して前記開口８ａが形成され、その開口８ａから管内に配線・配管材１が進入するように形成されている（図５および図６参照）。具体的には、掬上部１０は、その掬上部１０を配線・配管材１の外面に押し付けたときに当たる外形面１０ｃ（図示実施の形態においては、外側突状部１０ａの外面）が、先端ほど管内に向かうように傾斜して形成されている。ここにおいて、保護管本体２は、布設面２０上に前記掬上部１０を下にして自立すべく、その布設面２０に当接する当接部１１を有している。そこで、波付き部７から掬上部１０に移る折れ曲がり部分が、前記当接部１１となっている。   Further, when the heel portion 10 is pressed against the outer surface of the wiring / piping material 1, the split portion 8 is expanded to form the opening 8a, and the wiring / piping material 1 is formed in the pipe from the opening 8a. Is formed so as to enter (see FIGS. 5 and 6). Specifically, the upper portion 10 has an outer surface 10c (in the illustrated embodiment, the outer surface of the outer protruding portion 10a) that hits when the upper portion 10 is pressed against the outer surface of the wiring / piping material 1 as the tip. It is formed so as to be inclined toward the inside of the tube. Here, the protective tube main body 2 has an abutting portion 11 that abuts on the laying surface 20 so as to be self-supporting on the laying surface 20 with the collar upper part 10 facing down. Therefore, the bent portion that moves from the corrugated portion 7 to the heel portion 10 is the abutting portion 11.

また、保護管本体２は、弾性を備え、切割部８は、その弾性力に抗するように拡開し、その弾性力による復帰により閉じるようになっている。したがって、切割部８が拡開して開口８ａが形成されて配線・配管材１が保護管本体２の管内に進入すると、切割部８は、前記弾性力により自動的に閉じることとなる。なお、他の保護管本体３は、保護管本体２と同一の形状および構造を有している。   The protective tube main body 2 is provided with elasticity, and the cut portion 8 is expanded so as to resist the elastic force, and is closed by returning due to the elastic force. Therefore, when the cut portion 8 is expanded to form the opening 8a and the wiring / pipe material 1 enters the tube of the protective tube main body 2, the cut portion 8 is automatically closed by the elastic force. The other protective tube main body 3 has the same shape and structure as the protective tube main body 2.

一方、継手４は、図１および図２に示すように、保護管本体２と一体であって、保護管本体２の管壁６の一方の端からその長手方向に延設されるようにして筒形状に形成されている。そして、この継手４は、他の保護管本体３の端部（継手４が形成されていない側の端部）３ａにその外周面に対向する方向から被せられて前記端部３ａに外嵌されるように、保護管本体２の切割部８に連通するとともに前記筒形状の軸方向に連続する拡開可能な開放部４ａを有している（図２参照）。そして、継手４には、他の保護管本体３の外側凸部７ａ、７ａと嵌合するように、内面側に嵌合溝４ｂ、４ｂが設けられている。なお、この継手４と保護管本体２とからなる保護管５は、コルゲート成形により形成され、前記開放部４ａと切割部８とは、後加工による切除工程によって形成される。   On the other hand, as shown in FIGS. 1 and 2, the joint 4 is integral with the protective tube main body 2 and extends from one end of the tube wall 6 of the protective tube main body 2 in the longitudinal direction thereof. It is formed in a cylindrical shape. The joint 4 is fitted on the end 3a by covering the end 3a of the other protective tube body 3 (the end on the side where the joint 4 is not formed) 3a from the direction facing the outer peripheral surface. As shown in FIG. 2, it has an openable portion 4a that communicates with the cut portion 8 of the protective tube main body 2 and that is continuous in the axial direction of the cylindrical shape (see FIG. 2). The joint 4 is provided with fitting grooves 4b and 4b on the inner surface side so as to be fitted with the outer convex portions 7a and 7a of the other protective tube main body 3. The protective tube 5 including the joint 4 and the protective tube main body 2 is formed by corrugated molding, and the open portion 4a and the cut portion 8 are formed by a cutting process by post-processing.

ここにおいて、前記開放部４ａは、図２に示すように、少なくとも保護管本体２側が、切割部８よりも幅広に形成されて、その開放部４ａの、保護管本体２側の端縁が、他の保護管本体３に外嵌する際の、他の保護管本体３の端縁３ｂとの位置合わせ部４ｃとなっている（図１０参照）。特に、図示実施の形態においては、開放部４ａに、他の保護管本体３の端部３ａが入り込み、前記位置合わせ部４ｃと他の保護管本体３の端縁３ｂとが当接するようになっている（図９、図１０参照）。また、開放部４ａは、図９ないし図１３に示すように、その開放部４ａの周縁を前記他の保護管本体３の外面に押し付けることにより、拡開して、継手４内に前記他の保護管本体３が進入するような幅寸法を有している。この開放部４ａの幅寸法ｕは、継手４の外径に対して１／４〜１／２の範囲が好ましく、図示実施の形態においては１／３程度となっている（図２参照）。そして、この開放部４ａは、保護管本体２側に位置する一部の開放部が、先端側に比して若干幅広に形成されている。   Here, as shown in FIG. 2, at least the protective tube main body 2 side is formed wider than the split portion 8, and the open portion 4 a has an edge on the protective tube main body 2 side of the open portion 4 a. It is the alignment part 4c with the edge 3b of the other protective tube main body 3 at the time of external fitting to the other protective tube main body 3 (refer FIG. 10). In particular, in the illustrated embodiment, the end portion 3a of the other protective tube main body 3 enters the open portion 4a, and the alignment portion 4c and the end edge 3b of the other protective tube main body 3 come into contact with each other. (See FIGS. 9 and 10). Further, as shown in FIGS. 9 to 13, the open portion 4 a is expanded by pressing the peripheral edge of the open portion 4 a against the outer surface of the other protective tube body 3, and the other portion is inserted into the joint 4. The width is such that the protective tube main body 3 enters. The width u of the opening 4a is preferably in the range of 1/4 to 1/2 with respect to the outer diameter of the joint 4, and is about 1/3 in the illustrated embodiment (see FIG. 2). In the opening 4a, a part of the opening located on the protective tube main body 2 side is formed slightly wider than the tip side.

また、継手４は、保護管本体２と同様に、弾性を備えている。こうして、保護管本体２と継手４とからなる保護管５は、弾性を備えて、切割部８および開放部４ａは、その弾性力に抗するように拡開し、また、その弾性力による復帰により閉じるようになっている。   In addition, the joint 4 has elasticity similarly to the protective tube main body 2. Thus, the protective tube 5 composed of the protective tube main body 2 and the joint 4 has elasticity, and the cut portion 8 and the open portion 4a expand so as to resist the elastic force, and the return by the elastic force. It is designed to close.

次に、以上の構成からなる保護管本体２および保護管５の作用効果について説明する。配線・配管材１を、保護管本体２の管内に収容するには、図５に示すように、布設面２０上に、配線・配管材１を配置し、その配線・配管材１の上に、保護管本体２をその切割部８を下にして載せるように配置する。そして、切割部８を拡開して開口８ａを形成し、その開口８ａから管内に配線・配管材１を進入させる（図６および図７参照）。このとき、保護管本体２と一体に形成された継手４の開放部４ａもまた拡開し、その拡開した開放部４ａから、配線・配管材１が継手４の内部に進入する。その後、開口８ａを閉じると、配線・配管材１は、掬上部１０により掬い上げられて、管内に収容される（図７および図８参照）。そして、このように、配線・配管材１を保護管本体２の掬上部１０により掬い上げることで、配線・配管材１を簡単に保護管本体２の管内に収容して布設することができる。しかも、保護管本体２は、切割部８が下方を向いた状態で始めから配置されるため、保護管本体２を周方向に反転する必要もなく、切割部８から管内に雨水等が浸入するのを避けることができる。なお、保護管本体２の管内に配線・配管材１を収容した後には、切割部８が拡開しないように、必要に応じて、保護管本体２にはバンド等の締結具が取り付けられる。   Next, the effect of the protective tube main body 2 and the protective tube 5 which consist of the above structure is demonstrated. In order to accommodate the wiring / piping material 1 in the pipe of the protective tube main body 2, the wiring / piping material 1 is arranged on the laying surface 20 as shown in FIG. The protective tube main body 2 is arranged so that the cut portion 8 is placed downward. And the slit part 8 is expanded and the opening 8a is formed, and the wiring and piping material 1 are penetrated in the pipe | tube from the opening 8a (refer FIG. 6 and FIG. 7). At this time, the opening 4a of the joint 4 formed integrally with the protective tube main body 2 is also expanded, and the wiring / piping material 1 enters the inside of the joint 4 from the expanded opening 4a. Thereafter, when the opening 8a is closed, the wiring / piping material 1 is scooped up by the heel upper portion 10 and accommodated in the pipe (see FIGS. 7 and 8). Then, the wiring / piping material 1 can be easily accommodated in the pipe of the protective tube main body 2 and installed by scooping up the wiring / piping material 1 with the upper part 10 of the protective tube main body 2. Moreover, since the protective tube main body 2 is arranged from the beginning with the cut portion 8 facing downward, it is not necessary to reverse the protective tube main body 2 in the circumferential direction, and rainwater or the like enters the pipe from the cut portion 8. Can be avoided. In addition, after the wiring / pipe material 1 is accommodated in the pipe of the protective tube main body 2, a fastener such as a band is attached to the protective tube main body 2 as necessary so that the cut portion 8 does not expand.

ここにおいて、掬上部１０は、外側突状部１０ａと内側突状部１０ｂとが長手方向に交互に連続して並ぶようにして形成されており、この掬上部１０によって保護管本体２の可撓性を損なうということもない。そして、掬上部１０における外側突状部１０ａの外面と内側突状部１０ｂの内面との間隔Ｌ２が、波付き部７における外側凸部７ａの外面と内側凸部７ｂの内面との間隔Ｌ１よりも小さくなっているため、掬上部１０が、配線・配管材１を的確に掬い上げることができる。   Here, the flange upper part 10 is formed such that the outer protrusions 10a and the inner protrusions 10b are alternately arranged in the longitudinal direction. There is no loss of sex. And the space | interval L2 of the outer surface of the outer side protruding part 10a in the collar upper part 10 and the inner surface of the inner side protruding part 10b is from the space | interval L1 of the outer surface of the outer side convex part 7a in the wavy part 7 and the inner surface of the inner side convex part 7b. Therefore, the upper part 10 can accurately scoop up the wiring / piping material 1.

また、図５ないし図８に示すように、掬上部１０は、その掬上部１０を配線・配管材１の外面に押し付けることにより、切割部８が拡開して開口８ａが形成され、その開口８ａから管内に配線・配管材１が進入するように形成されている。したがって、その配線・配管材１を保護管本体２の管内に簡単に進入させることができる。さらに、保護管本体２は、布設面２０上に掬上部１０を下にして自立すべく、その布設面２０に当接する当接部１１を有している。そして、このように保護管本体２は、当接部１１が布設面２０に当接して自立することで、この保護管本体２は、布設面２０上に安定して布設される。   Further, as shown in FIG. 5 to FIG. 8, the flange upper portion 10 is formed by pressing the flange upper portion 10 against the outer surface of the wiring / piping material 1, so that the cut portion 8 is expanded and an opening 8 a is formed. The wiring / piping material 1 is formed so as to enter the pipe from 8a. Therefore, the wiring / piping material 1 can be easily entered into the tube of the protective tube main body 2. Furthermore, the protective tube main body 2 has an abutting portion 11 that abuts against the laying surface 20 so as to be self-supporting on the laying surface 20 with the ridge upper portion 10 facing down. In this way, the protective tube main body 2 is stably laid on the laying surface 20 by the contact portion 11 being in contact with the laying surface 20 and standing independently.

保護管５においては、保護管本体２と一体となった継手４が、軸方向に連続する開放部４ａを通して、他の保護管本体３の端部（継手４が形成されていない側の端部）３ａに外嵌されることで、これら保護管本体２と他の保護管本体３が接続される。このため、継手４を別途設ける必要もなく、保護管本体２、３どうし、ひいては保護管５、５を簡単に接続することができる。しかも、順次、保護管本体２（３）における、継手４が形成されていない側の端部に、次の保護管本体２を、その保護管本体２と一体となった継手４を介して接続すれば、多数の保護管本体２（３）、２（３）、ひいては多数の保護管５、５を連続して接続することができる。   In the protective tube 5, the joint 4 integrated with the protective tube main body 2 passes through the opening 4 a continuous in the axial direction, and the end of the other protective tube main body 3 (the end on the side where the joint 4 is not formed). ) The protective tube main body 2 and the other protective tube main body 3 are connected by being externally fitted to 3a. For this reason, it is not necessary to provide the joint 4 separately, and the protective tube main bodies 2 and 3 and by extension the protective tubes 5 and 5 can be easily connected. In addition, the next protective tube main body 2 is connected to the end of the protective tube main body 2 (3) on the side where the joint 4 is not formed, via the joint 4 integrated with the protective tube main body 2. By doing so, a large number of protective tube bodies 2 (3), 2 (3), and thus a large number of protective tubes 5, 5 can be connected in succession.

そして、継手４には、保護管本体２の切割部８に連通する開放部４ａが形成されているため、前記切割部８を拡開した開口８ａから、管内に配線・配管材１を進入させるにあたって、この継手４が、管内への配線・配管材１の進入を妨げることはない。したがって、継手４の開放部４ａを通して、保護管本体２と他の保護管本体３とを接続する際に、その接続と同時に、前記開口８ａから、保護管本体２の管内に配線・配管材１を進入させることもできる。   Since the joint 4 is formed with an open portion 4a communicating with the cut portion 8 of the protective tube main body 2, the wiring / pipe material 1 is caused to enter the pipe from the opening 8a in which the cut portion 8 is expanded. In this case, the joint 4 does not hinder the entry of the wiring / piping material 1 into the pipe. Therefore, when connecting the protective tube main body 2 and another protective tube main body 3 through the open part 4a of the joint 4, simultaneously with the connection, the wiring / piping material 1 enters the pipe of the protective tube main body 2 from the opening 8a. Can also be entered.

その上、継手４の開放部４ａは、その開放部４ａの周縁を他の保護管本体３の外面に押し付けることにより、拡開して、継手４内に、前記他の保護管本体３が進入するような幅寸法を有している。そして、このように、開放部４ａの周縁を、他の保護管本体３の外面に押し付けることで、開放部４ａが拡開して継手４内に他の保護管本体３が進入するため、保護管本体２、３どうしを、一層簡単に接続することができる。   In addition, the open portion 4 a of the joint 4 is expanded by pressing the periphery of the open portion 4 a against the outer surface of the other protective tube main body 3, and the other protective tube main body 3 enters the joint 4. It has such a width dimension. And since the open part 4a expands and the other protective tube main body 3 enters into the joint 4 by pressing the periphery of the open part 4a against the outer surface of the other protective tube main body 3 in this way, The pipe bodies 2 and 3 can be connected more easily.

また、継手４において、保護管本体２の切割部８よりも幅広に形成された開放部４ａにおける、保護管本体２側の端縁からなる位置合わせ部４ｃと、他の保護管本体３の端縁３ｂとを合わせることで（図示実施の形態においては、当接させることで）、保護管本体２と他の保護管本体３とを、長手方向の所定の位置で接続することができる（図９、図１０および図１３参照）。特に、図示実施の形態においては、開放部４ａは、保護管本体２側に位置する一部の開放部が、先端側に比して若干幅広に形成されていおり、位置合わせ部４ｃと、他の保護管本体３の端縁３ｂとを確実に当接させることができ、その位置合わせが的確に行なわれる。そして、この接続によって、継手４の嵌合溝４ｂと、他の保護管本体３の外側凸部７ａとが嵌合するため、保護管本体２、３どうしを長手方向に相対移動することなく確実に接続することができる（図１３参照）。   Further, in the joint 4, in the open portion 4 a formed wider than the split portion 8 of the protective tube main body 2, the alignment portion 4 c formed by the edge on the protective tube main body 2 side and the end of the other protective tube main body 3 By aligning with the edge 3b (in the illustrated embodiment, by contact), the protective tube main body 2 and the other protective tube main body 3 can be connected at a predetermined position in the longitudinal direction (see FIG. 9, FIG. 10 and FIG. 13). In particular, in the illustrated embodiment, the opening portion 4a is formed such that a part of the opening portion located on the protective tube main body 2 side is slightly wider than the distal end side. The protective tube main body 3 can be reliably brought into contact with the edge 3b of the protective tube main body 3, and the alignment is performed accurately. And since the fitting groove 4b of the joint 4 and the outer convex part 7a of the other protective tube main body 3 are fitted by this connection, the protective tube main bodies 2 and 3 are reliably moved without moving relative to each other in the longitudinal direction. (See FIG. 13).

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、掬上部１０における外側突状部１０ａの外面と内側突状部１０ｂの内面との間隔Ｌ２は、波付き部７における外側凸部７ａおよび内側凸部７ｂ側から切割部８側に向かうにつれて漸次小さくならなくとも、この掬上部１０は、少なくとも先端部分が平板状に形成されてもよい。そして、このように掬上部１０の先端部分が平板状に形成される場合には、この掬上部１０が、配線・配管材１をより的確に掬い上げることができる。   In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the distance L2 between the outer surface of the outer protruding portion 10a and the inner surface of the inner protruding portion 10b in the heel portion 10 increases from the outer protruding portion 7a and inner protruding portion 7b side of the corrugated portion 7 toward the cut portion 8 side. Even if the heel portion 10 is not gradually reduced, at least the tip portion may be formed in a flat plate shape. And when the front-end | tip part of the collar upper part 10 is formed in flat form in this way, this collar upper part 10 can scoop up the wiring and piping material 1 more correctly.

また、保護管本体２は、例えばヒンジ部９が弾性を備えて、切割部８が、その弾性力に抗するように拡開し、さらに、その弾性力による復帰により閉じるが、保護管本体２は、切割部８を拡開して開口８ａを形成すると、その開状態が維持され、その開口８ａを閉じると、その閉状態が維持されるよう形成されてもよい。すなわち、保護管本体２は、例えばヒンジ部９が塑性を備えていたり、また、ヒンジ部９が任意の角度で止まるように構成されていてもよい。   In addition, the protective tube main body 2 has, for example, the hinge portion 9 provided with elasticity, and the cut portion 8 is expanded so as to resist the elastic force, and is further closed by returning due to the elastic force. May be formed such that the open state is maintained when the cut portion 8 is expanded to form the opening 8a, and the closed state is maintained when the opening 8a is closed. That is, the protective tube main body 2 may be configured such that, for example, the hinge portion 9 has plasticity, or the hinge portion 9 stops at an arbitrary angle.

また、保護管本体２は、ヒンジ部９を備えなくとも、管壁６全体が弾性変形あるいは塑性変形するものであってもよい。   Further, the protection tube main body 2 may be one in which the entire tube wall 6 is elastically deformed or plastically deformed even though the hinge portion 9 is not provided.

また、保護管本体２の管壁６には、切割部８の両側に、掬上部１０を備えているが、図１４に示すように、この掬上部１０はなくともよい。   Moreover, the pipe wall 6 of the protective tube main body 2 is provided with the ridge upper part 10 on both sides of the cutting part 8, but the ridge upper part 10 may not be provided as shown in FIG.
