Description

この発明は、老朽化した下水管路、上水管路、農業用水路、ガス管路などの既設管を更生する更生管を製管する際に用いられる補強材入り帯状部材及びその製造方法に関するものである。   TECHNICAL FIELD The present invention relates to a band member with a reinforcing material used for manufacturing a rehabilitation pipe for rehabilitating an existing pipe such as an aged sewer pipe, a water pipe, an agricultural water pipe, and a gas pipe, and a method for manufacturing the same. is there.

従来より、更生管を製管する帯状部材として、プラスチック製帯状部材のリブに鋼板等の金属製補強板材を埋設した補強材入り帯状部材が知られている（例えば、特許文献１参照）。このような補強材入り帯状部材は、マンホール内に設置された製管機に供給され、製管機によってそのリブを外周側に位置して螺旋状に巻き回される。そして、螺旋状に巻き回されて隣接する補強材入り帯状部材の一方の側縁部、他方の側縁部の少なくとも一つに溶融樹脂が塗布されるとともに、隣接する補強材入り帯状部材の一方の側縁部及び他方の側縁部が重ね合わされて一体に融着されることにより、更生管が製管され、製管された更生管が回転させられて既設管内に挿入される。その後、更生管と既設管との間隙にモルタルが充填され、既設管がモルタル及び更生管からなる複合管によって更生される（例えば、特許文献２参照）。   Conventionally, as a band-shaped member for manufacturing a rehabilitated pipe, a band-shaped member with a reinforcing material in which a metal reinforcing plate such as a steel plate is embedded in a rib of a plastic band-shaped member is known (for example, see Patent Document 1). Such a belt-like member with a reinforcing material is supplied to a pipe making machine installed in a manhole, and the rib is positioned on the outer peripheral side by the pipe making machine and is wound spirally. Then, the molten resin is applied to at least one of the side edge portions and the other side edge portion of the adjacent reinforcing material-containing band-shaped member wound spirally, and one of the adjacent reinforcing material-containing band-shaped members The side edge portion and the other side edge portion are overlapped and fused together, whereby the rehabilitated tube is manufactured, and the regenerated tube is rotated and inserted into the existing tube. Thereafter, the gap between the rehabilitated pipe and the existing pipe is filled with mortar, and the existing pipe is rehabilitated by a composite pipe composed of the mortar and the rehabilitated pipe (see, for example, Patent Document 2).

このような複合管にあっては、モルタル中にリブに埋設された金属製補強板材が立設状態で配設されることにより、土圧や外水圧などに対する強度を高めることができる。   In such a composite pipe, the strength against earth pressure or external water pressure can be increased by arranging the metal reinforcing plate material embedded in the rib in the mortar in a standing state.

特表２００５−５２８２４３号公報JP 2005-528243 Gazette 特表２００８−５３６０２７号公報Special table 2008-536027 gazette

ところで、前述した補強材入り帯状部材は、ポリエチレンを押出成形してポリエチレン製帯状部材を形成し、当該ポリエチレン製帯状部材のリブの溝に金属製補強板材を連続的に導入した後、ポリエチレン製帯状部材のリブの頂部にポリエチレンを押出成形してポリエチレン製被覆部をリブと一体に融着し、金属製補強板材を封入することにより製造される。そして、補強材入り帯状部材を用いて更生管を製管するとき、万が一製管不良が発生すると、更生管を形成する螺旋状の隣接する補強材入り帯状部材は溶融樹脂によって一体に融着されていることから、元の補強材入り帯状部材に戻すことは不可能である。このため、製管不良が発生すると、それまでに製管された更生管を既設管から撤去し、改めて更生管を製管する必要があり、多くの手間が必要になるとともに、それまでに製管された更生管が無駄になるという問題があった。   By the way, the above-described band member with reinforcing material is formed by extruding polyethylene to form a polyethylene band member, and after continuously introducing a metal reinforcing plate into the groove of the rib of the polyethylene band member, It is manufactured by extruding polyethylene at the top of the rib of the member, fusing the polyethylene coating part integrally with the rib, and enclosing a metal reinforcing plate. When a rehabilitation pipe is produced using a reinforcing material-containing band-like member, if a defective pipe is produced, the adjacent spiral-like reinforcing material-containing band-like member forming the rehabilitation pipe is integrally fused with the molten resin. Therefore, it is impossible to return to the original band member with the reinforcing material. For this reason, when a fault occurs in pipe making, it is necessary to remove the rehabilitated pipe that has been made so far from the existing pipe and make a new renewed pipe. There was a problem that the rehabilitated pipe wasted.

また、溶融樹脂は速やかに流動性を喪失することから、融着樹脂を成形する成形機を製管機に搭載しなければならず、設置に際して大きな空間を必要とする。また、既設管内を回転できるように小型化することは極めて困難である。このため、製管機の設置位置がマンホールに限定され、マンホール内で製管された更生管を回転させながら既設管内に送り込む製管方法を採用せざるを得ない。すなわち、製管機を既設管内に設置し、既設管の回りを公転させて更生管を製管し、製管された更生管を既設管内に残置させる製管方法を採用することはできない。これにより、更生管の製管に伴って既設管に対する更生管の摩擦抵抗が増大することが避けられず、製管距離が限定され、また、製管される更生管の形状が円形に限定される、すなわち、円形状の既設管を更生する場合に限定されるという問題があった。   In addition, since the molten resin quickly loses its fluidity, a molding machine for molding the fusion resin must be mounted on the pipe making machine, and a large space is required for installation. Moreover, it is extremely difficult to reduce the size so that the existing pipe can be rotated. For this reason, the installation position of the pipe making machine is limited to the manhole, and a pipe making method in which the renovated pipe produced in the manhole is fed into the existing pipe while being rotated has to be adopted. That is, it is not possible to adopt a pipe making method in which a pipe making machine is installed in an existing pipe, a rehabilitated pipe is produced by revolving around the existing pipe, and the produced renovated pipe is left in the existing pipe. As a result, it is inevitable that the frictional resistance of the rehabilitated pipe with respect to the existing pipe increases with the production of the rehabilitated pipe, the pipe making distance is limited, and the shape of the regenerated pipe to be produced is limited to a circle. In other words, there is a problem that it is limited to rehabilitation of a circular existing pipe.

また、ポリエチレン製帯状部材は、硬質塩化ビニルに比較して剛性が低いため、これまでの硬質塩化ビニル製帯状部材のように、各側縁部に互いに接合可能な接合凹部及び接合凸部を形成し、螺旋状に巻き回して隣接する帯状部材の接合凹部及び接合凸部を互いに接合して更生管を製管したとしても、管として機能しないものである。すなわち、ポリエチレン製帯状部材の各側縁部に互いに接合可能な接合凹部及び接合凸部を形成し、螺旋状に巻き回して隣接する接合凹部及び接合凸部を互いに接合して更生管を製管した場合、接合部から漏水することを避けることができないものである。   In addition, since polyethylene strips are less rigid than hard vinyl chloride, they form joint recesses and joints that can be joined to each side edge like conventional hard vinyl chloride strips. And even if it winds helically and joins the joint recessed part and joining convex part of an adjacent strip | belt-shaped member mutually, and manufactures a rehabilitation pipe | tube, it does not function as a pipe | tube. That is, a joint concave portion and a joint convex portion that can be joined to each other are formed on each side edge portion of the polyethylene belt-shaped member, and the regenerated pipe is manufactured by spirally winding and joining the adjacent joint concave portion and the joint convex portion to each other. In such a case, it is inevitable that water leaks from the joint.

これらのことから、補強材入り帯状部材における帯状部材の材料をポリエチレンから硬質塩化ビニルに変更することが考えられるが、従来と同様の製造方法によって補強材入り帯状部材を製造した場合、具体的には、硬質塩化ビニルを押出成形して硬質塩化ビニル製帯状部材を形成した後、該硬質塩化ビニル製帯状部材のリブに金属製補強板材を連続的に導入し、次いで、金属製補強板材を封入するように、硬質塩化ビニルを押出成形して硬質塩化ビニル製被覆部を融着させた場合、硬質塩化ビニル製帯状部材に対する硬質塩化ビニル製被覆部の融着強度が弱く、螺旋状に巻き回して更生管を製管する場合のように、曲げが作用する用途においては、硬質塩化ビニル製帯状部材から硬質塩化ビニル製被覆部が剥離し、金属製補強板材がリブから飛び出して外れてしまうため、採用することはできないものである。   From these, it is conceivable to change the material of the band-shaped member in the band-shaped member with the reinforcing material from polyethylene to hard vinyl chloride, but when the band-shaped member with the reinforcing material is manufactured by the same manufacturing method as before, specifically, After extruding hard vinyl chloride to form a hard vinyl chloride strip member, continuously introducing a metal reinforcing plate into the rib of the hard vinyl chloride strip member, and then enclosing the metal reinforcing plate member Thus, when hard vinyl chloride is extruded and fused with a hard vinyl chloride coating, the fusion strength of the hard vinyl chloride coating with respect to the hard vinyl chloride strip is weak and it is spirally wound. In applications where bending is applied, such as when making rehabilitated pipes, the hard vinyl chloride coating is peeled off from the hard vinyl chloride strip and the metal reinforcing plate is ribbed. Order to deviate jump out, are those that can not be adopted.

なお、特開平２−５０２５５５号公報に記載されるように、金型に鋼板等の補強材を挿入し、塩化ビニル樹脂を押出成形して被覆することも知られているが、被覆樹脂の収縮と鋼板等の収縮との差に基づいて成形品に波打ちが発生し、採用することはできない。   In addition, as described in JP-A-2-502555, it is also known that a reinforcing material such as a steel plate is inserted into a mold and a vinyl chloride resin is extruded to cover the resin. Based on the difference between the shrinkage of the steel plate and the like, the molded product is wavy and cannot be employed.

本発明は、このような問題点に鑑みてなされたもので、剛性の大きな硬質塩化ビニルによって帯状部材が形成されるとともに、曲げが作用してもリブからの飛び出しを抑えて金属製補強板材をリブに埋設することのできる補強材入り帯状部材及びその製造方法を提供するものである。   The present invention has been made in view of such problems, and a band-shaped member is formed of hard vinyl chloride having a large rigidity. A belt-like member with a reinforcing material that can be embedded in a rib and a method for manufacturing the same are provided.

本発明の補強材入り帯状部材は、両側縁部に接合部が形成され、螺旋状に巻き回すとともに、隣接する接合部同士を互いに接合して更生管を製管する補強材入り帯状部材であって、補強材入り帯状部材は、帯板状の基板、該基板から直立する複数本のリブ、基板の一側縁部及び他側縁部にそれぞれ立設された接合部を備えた硬質塩化ビニル製帯状部材と、硬質塩化ビニル製帯状部材の各リブに埋設された金属製補強板材と、金属製補強板材が埋設された硬質塩化ビニル製帯状部材のリブの頂部及びその周縁部に融着された軟質塩化ビニル製封閉部とから構成されることを特徴とするものである。   The band member with a reinforcing material of the present invention is a band member with a reinforcing material in which joints are formed on both side edges, wound spirally, and adjacent joints are joined to each other to produce a rehabilitated pipe. The stiffener-containing band-shaped member is a hard vinyl chloride provided with a band-plate-shaped substrate, a plurality of ribs standing upright from the substrate, and joints erected on one side edge and the other side edge of the substrate. The belt-shaped member, the metal reinforcing plate embedded in each rib of the hard vinyl chloride strip-shaped member, and the top of the rib of the hard vinyl chloride strip-shaped member embedded with the metal reinforcing plate and the peripheral portion thereof are fused. And a soft vinyl chloride sealing part.

本発明によれば、硬質塩化ビニル製帯状部材のリブの頂部及びその周縁部に軟質塩化ビニル製封閉部が一体に融着されているため、補強材入り帯状部材を、リブを立設した側が外周面側に位置するように螺旋状に巻き回し、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することによって補強材入り帯状部材に曲げが作用しても、硬質塩化ビニル製帯状部材から軟質塩化ビニル製封閉部が剥離することはなく、金属製補強板材の飛び出しを抑えてより高剛性の更生管を製管することができる。この際、更生管は、剛性の大きな硬質塩化ビニル製帯状部材の接合部同士を互いに接合して製管されるため、接合部からの漏水を防止できる。しかも、仮に隣接する補強材入り帯状部材の接合部同士が不完全に接合したとしても、その接合部の接合を解除することができることから、接合部の接合を解除して補強材入り帯状部材を巻き戻した後、更生管の製管作業を再開することができ、既に製管された更生管及び補強材入り帯状部材を無駄にすることはない。また、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することから、これまでの製管方法を作業環境に対応して選択することができる。   According to the present invention, since the sealing portion made of the soft vinyl chloride is integrally fused to the top portion of the rib of the hard vinyl chloride strip member and the peripheral portion thereof, the side where the rib is erected is provided on the side where the rib is erected. Even if bending is applied to the band member with the reinforcing material by winding it spirally so as to be located on the outer peripheral surface side, and joining the joining portions of the adjacent band members with the reinforcing material to each other to produce a rehabilitating pipe In addition, the sealing portion made of soft vinyl chloride does not peel off from the hard vinyl chloride belt-like member, and a more rigid rehabilitating tube can be made by suppressing the metal reinforcing plate from popping out. At this time, the rehabilitating pipe is manufactured by joining the joint portions of the rigid vinyl chloride belt-like members to each other, so that leakage from the joint portion can be prevented. Moreover, even if the joining portions of the adjacent reinforcing material-containing band-like members are incompletely joined together, the joining of the joining portions can be released. After the rewinding, the rehabilitating pipe can be resumed, and the rehabilitated pipe already formed and the band member with the reinforcing material are not wasted. Moreover, since the joining part of the adjacent strip | belt member with a reinforcing material mutually joins, and a rehabilitation pipe is manufactured, the conventional pipe manufacturing method can be selected corresponding to a working environment.

本発明の補強材入り帯状部材は、両側縁部に接合部が形成され、螺旋状に巻き回すとともに、隣接する接合部同士を互いに接合して更生管を製管する補強材入り帯状部材であって、補強材入り帯状部材は、帯板状の基板、該基板から直立するとともに、頂部にそれぞれ側方に突出する突出部が形成された複数本のリブ、基板の一側縁部及び他側縁部にそれぞれ立設された接合部を備えた硬質塩化ビニル製帯状部材と、硬質塩化ビニル製帯状部材の各リブに埋設された金属製補強板材と、金属製補強板材が埋設された硬質塩化ビニル製帯状部材のリブの頂部及び突出部上に融着された軟質塩化ビニル製封閉部とから構成されることを特徴とするものである。   The band member with a reinforcing material of the present invention is a band member with a reinforcing material in which joints are formed on both side edges, wound spirally, and adjacent joints are joined to each other to produce a rehabilitated pipe. The reinforcing member-containing band-shaped member includes a band-shaped substrate, a plurality of ribs that stand upright from the substrate, and that have protrusions protruding laterally at the top, one side edge and the other side of the substrate Rigid vinyl chloride strips with joints erected at the edges, metal reinforcement plates embedded in each rib of the rigid vinyl chloride strips, and hard chlorides embedded with metal reinforcement plates It is characterized by comprising a top portion of a rib of a vinyl belt-shaped member and a soft vinyl chloride sealing portion fused on the protruding portion.

本発明によれば、硬質塩化ビニル製帯状部材のリブの頂部及び突出部上に軟質塩化ビニル製封閉部が一体に融着されているため、補強材入り帯状部材を、リブを立設した側が外周面側に位置するように螺旋状に巻き回し、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することによって補強材入り帯状部材に曲げが作用しても、硬質塩化ビニル製帯状部材から軟質塩化ビニル製封閉部が剥離することはなく、金属製補強板材の飛び出しを抑えてより高剛性の更生管を製管することができる。この際、更生管は、剛性の大きな硬質塩化ビニル製帯状部材の接合部同士を互いに接合して製管されるため、接合部からの漏水を防止できる。しかも、仮に隣接する補強材入り帯状部材の接合部同士が不完全に接合したとしても、その接合部の接合を解除することができることから、接合部の接合を解除して補強材入り帯状部材を巻き戻した後、更生管の製管作業を再開することができ、既に製管された更生管及び補強材入り帯状部材を無駄にすることはない。また、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することから、これまでの製管方法を作業環境に対応して選択することができる。   According to the present invention, since the sealing portion made of soft vinyl chloride is integrally fused on the top and the protruding portion of the rib of the hard vinyl chloride strip, the side where the rib is erected is provided on the side where the rib is erected. Even if bending is applied to the band member with the reinforcing material by winding it spirally so as to be located on the outer peripheral surface side, and joining the joining portions of the adjacent band members with the reinforcing material to each other to produce a rehabilitating pipe In addition, the sealing portion made of soft vinyl chloride does not peel off from the hard vinyl chloride belt-like member, and a more rigid rehabilitating tube can be made by suppressing the metal reinforcing plate from popping out. At this time, the rehabilitating pipe is manufactured by joining the joint portions of the rigid vinyl chloride belt-like members to each other, so that leakage from the joint portion can be prevented. Moreover, even if the joining portions of the adjacent reinforcing material-containing band-like members are incompletely joined together, the joining of the joining portions can be released. After the rewinding, the rehabilitating pipe can be resumed, and the rehabilitated pipe already formed and the band member with the reinforcing material are not wasted. Moreover, since the joining part of the adjacent strip | belt member with a reinforcing material mutually joins, and a rehabilitation pipe is manufactured, the conventional pipe manufacturing method can be selected corresponding to a working environment.

本発明の補強材入り帯状部材は、両側縁部に接合部が形成され、螺旋状に巻き回すとともに、隣接する接合部同士を互いに接合して更生管を製管する補強材入り帯状部材であって、補強材入り帯状部材は、帯板状の基板、該基板から直立するとともに、頂部にそれぞれ側方に突出する突出部が形成された複数本のリブ、基板の一側縁部及び他側縁部にそれぞれ立設された接合部を備えた硬質塩化ビニル製帯状部材と、硬質塩化ビニル製帯状部材の各リブに埋設された金属製補強板材と、金属製補強板材が埋設された硬質塩化ビニル製帯状部材のリブの頂部及び突出部を包囲して融着された軟質塩化ビニル製封閉部とから構成されることを特徴とするものである。   The band member with a reinforcing material of the present invention is a band member with a reinforcing material in which joints are formed on both side edges, wound spirally, and adjacent joints are joined to each other to produce a rehabilitated pipe. The reinforcing member-containing band-shaped member includes a band-shaped substrate, a plurality of ribs that stand upright from the substrate, and that have protrusions protruding laterally at the top, one side edge and the other side of the substrate Rigid vinyl chloride strips with joints erected at the edges, metal reinforcement plates embedded in each rib of the rigid vinyl chloride strips, and hard chlorides embedded with metal reinforcement plates It is characterized by comprising a soft vinyl chloride sealing portion that surrounds and fuses the top of the rib and the protruding portion of the vinyl belt-shaped member.

本発明によれば、硬質塩化ビニル製帯状部材のリブの頂部及び突出部を包囲して軟質塩化ビニル製封閉部が一体に融着されているため、補強材入り帯状部材を、リブを立設した側が外周面側に位置するように螺旋状に巻き回し、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することによって補強材入り帯状部材に曲げが作用しても、硬質塩化ビニル製帯状部材から軟質塩化ビニル製封閉部が剥離することはなく、金属製補強板材の飛び出しを抑えてより高剛性の更生管を製管することができる。この際、更生管は、剛性の大きな硬質塩化ビニル製帯状部材の接合部同士を互いに接合して製管されるため、接合部からの漏水を防止できる。しかも、仮に隣接する補強材入り帯状部材の接合部同士が不完全に接合したとしても、その接合部の接合を解除することができることから、接合部の接合を解除して補強材入り帯状部材を巻き戻した後、更生管の製管作業を再開することができ、既に製管された更生管及び補強材入り帯状部材を無駄にすることはない。また、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管することから、これまでの製管方法を作業環境に対応して選択することができる。   According to the present invention, since the sealing portion made of soft vinyl chloride surrounds the top and the protruding portion of the rib of the hard vinyl chloride belt-shaped member and is integrally fused, It is wound on the reinforcing band member by winding it spirally so that the finished side is located on the outer peripheral surface side, and joining the joint portions of the adjacent reinforcing member band members together to produce a rehabilitation pipe. However, the sealing portion made of soft vinyl chloride is not peeled off from the hard vinyl chloride belt-like member, and a higher-rigidity rehabilitating tube can be made while suppressing the metal reinforcing plate from popping out. At this time, the rehabilitating pipe is manufactured by joining the joint portions of the rigid vinyl chloride belt-like members to each other, so that leakage from the joint portion can be prevented. Moreover, even if the joining portions of the adjacent reinforcing material-containing band-like members are incompletely joined together, the joining of the joining portions can be released. After the rewinding, the rehabilitating pipe can be resumed, and the rehabilitated pipe already formed and the band member with the reinforcing material are not wasted. Moreover, since the joining part of the adjacent strip | belt member with a reinforcing material mutually joins, and a rehabilitation pipe is manufactured, the conventional pipe manufacturing method can be selected corresponding to a working environment.

There is no need to do so, and a more rigid rehabilitation pipe can be produced while suppressing the metal reinforcing plate from popping out. At this time, the rehabilitating pipe is manufactured by joining the joint portions of the rigid vinyl chloride belt-like members to each other, so that leakage from the joint portion can be prevented.

Therefore, the metal reinforcing plate is embedded in the rib of the rigid rigid vinyl chloride belt-like member, and the reinforcing material-containing belt-like member that can prevent the metal reinforcing plate from popping out of the rib even when bending is applied continuously. Can be manufactured automatically.

本発明の補強材入り帯状部材の製造方法は、請求項６に記載の補強材入り帯状部材の製造方法であって、硬質塩化ビニルを押出成形して各リブに金属製補強板材を埋設可能な溝が形成されるとともに、その頂部にそれぞれ側方に突出する突出部が形成された硬質塩化ビニル製帯状部材を形成し、硬質塩化ビニル製帯状部材の各リブの溝に、周面が軟質塩化ビニルによって被覆された金属製補強板材を導入し、次いで、硬質塩化ビニル製帯状部材の各リブを加熱して金属製補強板材を被覆する軟質塩化ビニルを溶融させ、金属製補強板材を封入する軟質塩化ビニル製接着部を溝の内面に形成することを特徴とするものである。   The manufacturing method of the band member with a reinforcing material according to the present invention is a method for manufacturing the band member with a reinforcing material according to claim 6, and is capable of embedding a metal reinforcing plate in each rib by extruding hard vinyl chloride. A hard vinyl chloride belt-like member is formed with a groove formed and a protruding part protruding laterally at the top, and the peripheral surface is soft chloride in the groove of each rib of the hard vinyl chloride belt-like member. Introducing a metal reinforcing plate covered with vinyl, then heating each rib of the hard vinyl chloride strip to melt the soft vinyl chloride covering the metal reinforcing plate, and encapsulating the metal reinforcing plate The adhesive portion made of vinyl chloride is formed on the inner surface of the groove.

本発明によれば、硬質塩化ビニルを押出成形して各リブに金属製補強板材を埋設可能な溝が形成されるとともに、その頂部にそれぞれ側方に突出する突出部が形成された硬質塩化ビニル製帯状部材を形成した後、硬質塩化ビニル製帯状部材の各リブの溝に、周面が軟質塩化ビニルによって被覆された金属製補強板材を導入する。次いで、金属製補強板材が導入された硬質塩化ビニル製帯状部材の各リブを加熱して金属製補強板材を被覆する軟質塩化ビニルを溶融させ、溝の内面に軟質塩化ビニル製接着部を形成して硬質塩化ビニル製帯状部材のリブに導入された金属製補強板材を封入する。これにより、補強材入り帯状部材を螺旋状に巻き回し、隣接する補強材入り帯状部材の接合部同士を互いに接合して更生管を製管した際、補強材入り帯状部材に曲げが作用しても、硬質塩化ビニル製帯状部材のリブの溝内面に、金属製補強板材の周面に被覆された軟質塩化ビニルからなる軟質塩化ビニル製接着部が一体に融着されているため、両者が剥離することを確実に防止できる。したがって、剛性の高い硬質塩化ビニル製帯状部材のリブに金属製補強板材を埋設するとともに、曲げが作用してもリブからの金属製補強板材の飛び出しを抑えることのできる補強材入り帯状部材を連続的に製造することができる。   According to the present invention, hard vinyl chloride is formed by extruding hard vinyl chloride to form a groove in which a metal reinforcing plate can be embedded in each rib, and a protrusion protruding laterally is formed on the top of the groove. After forming the band member, a metal reinforcing plate whose peripheral surface is covered with soft vinyl chloride is introduced into the groove of each rib of the hard vinyl chloride band member. Next, each of the ribs of the hard vinyl chloride belt member introduced with the metal reinforcing plate is heated to melt the soft vinyl chloride covering the metal reinforcing plate, thereby forming a soft vinyl chloride adhesive portion on the inner surface of the groove. Then, a metal reinforcing plate introduced into the rib of the hard vinyl chloride belt-shaped member is enclosed. Thus, when the band member with reinforcing material is spirally wound and the joint portions of the adjacent band members with reinforcing material are joined to each other to form a rehabilitation pipe, bending is applied to the band member with reinforcing material. Also, since the soft vinyl chloride adhesive part made of soft vinyl chloride coated on the peripheral surface of the metal reinforcing plate is integrally fused to the groove inner surface of the rib of the hard vinyl chloride belt-shaped member, both peel off Can be surely prevented. Therefore, the metal reinforcing plate is embedded in the rib of the rigid rigid vinyl chloride belt-like member, and the reinforcing material-containing belt-like member that can prevent the metal reinforcing plate from popping out of the rib even when bending is applied continuously. Can be manufactured automatically.

以下、本発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１には、本発明の補強材入り帯状部材１の一実施形態が示されている。   FIG. 1 shows an embodiment of a band member 1 with a reinforcing material of the present invention.

この補強材入り帯状部材１は、剛性の大きな硬質塩化ビニル製帯状部材２と、この硬質塩化ビニル製帯状部材２のリブ２２に埋設された鋼板等の金属製補強板材３と、金属製補強板材３が埋設された硬質塩化ビニル製帯状部材２のリブ２２の頂部及びその周縁部に一体に融着された軟質塩化ビニル製封閉部４とから構成されている。   This reinforcing material-containing band-shaped member 1 includes a rigid rigid vinyl chloride band-shaped member 2, a metal reinforcing plate material 3 such as a steel plate embedded in a rib 22 of the hard vinyl chloride-shaped band member 2, and a metallic reinforcing plate material. 3 is composed of a top portion of the rib 22 of the rigid vinyl chloride belt-like member 2 in which 3 is embedded and a soft vinyl chloride sealing portion 4 fused integrally to the peripheral portion thereof.

ここで、塩化ビニルにおいて、引張弾性率が１５００ＭＰａ以上のものを硬質塩化ビニルといい、引張破断時の伸びが１８０％以上のものを軟質塩化ビニルという（「図解プラスチック用語辞典」、第２版、日刊工業新聞社、２０００年４月２８日 参照）。   Here, in vinyl chloride, a material having a tensile modulus of elasticity of 1500 MPa or more is called hard vinyl chloride, and a material having an elongation at break of 180% or more is called soft vinyl chloride (“Drawing Plastic Glossary”, 2nd edition, Nikkan Kogyo Shimbun, April 28, 2000).

硬質塩化ビニル製帯状部材２は、硬質塩化ビニルを押出成形して形成され、帯板状の基板２１と、該基板２１の裏面に基板２１に直交して立設された複数本（実施例においては３本）の断面略Ｉ字状のリブ２２と、基板２１の一側縁部の裏面に立設された接合凸部２３と、基板２１の他側縁部の裏面に立設され、接合凸部２３が嵌入し得る接合凹部２４とを備え、接合凹部２４が設けられた基板２１の他側縁部が、隣接する硬質塩化ビニル製帯状部材２における基板２１の一側縁部を配置できるように、基板２１の厚みだけ裏面側に段落ちした段落ち部２５に形成されるとともに、段落ち部２５に連続して、基板２１から離れるにつれて接合凹部２４の突出側に位置するように傾斜された傾斜リブ２６が形成されている。そして、各リブ２２には、金属製補強板材３を配置できるように、金属製補強板材３に対応する溝２２ａが形成されている。   The hard vinyl chloride strip-shaped member 2 is formed by extrusion molding of hard vinyl chloride, and includes a strip-shaped substrate 21 and a plurality of (in the embodiment,) standing upright on the back surface of the substrate 21 perpendicular to the substrate 21. 3) ribs 22 having a substantially I-shaped cross-section, a joint protrusion 23 erected on the back surface of one side edge of the substrate 21, and a rib erected on the back surface of the other side edge of the substrate 21. A projection recess 23 into which the projection 23 can be fitted, and the other side edge of the substrate 21 provided with the junction recess 24 can be arranged on one side edge of the substrate 21 in the adjacent band member 2 made of hard vinyl chloride. In this way, the thickness of the substrate 21 is formed in the stepped portion 25 stepped down on the back surface side, and is continuous to the stepped portion 25 and is inclined so as to be positioned on the protruding side of the bonding recess 24 as the distance from the substrate 21 increases. The inclined rib 26 is formed. Each rib 22 has a groove 22a corresponding to the metal reinforcing plate 3 so that the metal reinforcing plate 3 can be disposed.

なお、基板２１の一側縁部の裏面にゴム等のエラストマー５を配設し、後述するように、隣接する補強材入り帯状部材１の他側縁部に形成された段落ち部２５に一側縁部を配置した際、隣接する補強材入り帯状部材１，１における基板２１，２１の一側縁部と他側縁部との重ね合わせ部をエラストマー５によって密封することが好ましい。   In addition, an elastomer 5 such as rubber is disposed on the back surface of one side edge of the substrate 21, and, as will be described later, a stepped portion 25 formed on the other side edge of the adjacent reinforcing material-containing band-like member 1 is provided. When the side edge portions are arranged, it is preferable to seal the overlapping portions of the one side edge portions and the other side edge portions of the substrates 21, 21 in the adjacent band members 1, 1 with the reinforcing material with the elastomer 5.

金属製補強板材３は、リブ２２に対応して鋼板等を切断して形成され、硬質塩化ビニル製帯状部材２の各リブ２２の溝２２ａにその全長にわたって埋設されている。   The metal reinforcing plate 3 is formed by cutting a steel plate or the like corresponding to the rib 22, and is embedded in the groove 22 a of each rib 22 of the hard vinyl chloride belt-like member 2 over the entire length thereof.

この場合、金属製補強板材３としては、設定厚みの１枚の板材の他、薄板材を１回あるいは複数回折り畳んで設定厚みに形成したものでも構わない。   In this case, the metal reinforcing plate 3 may be a single plate having a set thickness, or a thin plate formed once or a plurality of times may be folded to form a set thickness.

軟質塩化ビニル製封閉部４は、軟質塩化ビニルを押出成形して形成され、硬質塩化ビニル製帯状部材２の各リブ２２に配設された金属製補強板材３を封入するように、リブ２２の頂部及びその周縁部に一体に融着されている。   The soft vinyl chloride sealing portion 4 is formed by extruding soft vinyl chloride and encloses the metal reinforcing plate 3 disposed on each rib 22 of the hard vinyl chloride belt-like member 2 so as to enclose the ribs 22. The top part and its peripheral part are fused together.

このような補強材入り帯状部材１は、まず、硬質塩化ビニルを押出成形して硬質塩化ビニル製帯状部材２を形成する（図２（ａ）参照）。この際、エラストマー５を共押出成形して基板２１の一方の側縁部に融着する。次いで、硬質塩化ビニル製帯状部材２における各リブ２２の溝２２ａに鋼板等の金属製補強板材３を連続的に導入する（図２（ｂ）参照）。この後、硬質塩化ビニル製帯状部材２のリブ２２に金属製補強板材３を封入するように、リブ２２の頂部及びその周縁部に軟質塩化ビニルを押出成形し、硬質塩化ビニル製帯状部材２のリブ２２に軟質塩化ビニル製封閉部４を一体に融着して製造される（図２（ｃ）参照）。   In such a band member 1 with a reinforcing material, first, hard vinyl chloride is extruded to form a hard vinyl chloride band member 2 (see FIG. 2A). At this time, the elastomer 5 is co-extruded and fused to one side edge of the substrate 21. Next, a metal reinforcing plate 3 such as a steel plate is continuously introduced into the groove 22a of each rib 22 in the hard vinyl chloride belt-shaped member 2 (see FIG. 2B). Thereafter, soft vinyl chloride is extruded at the top of the rib 22 and its peripheral edge so as to enclose the metal reinforcing plate 3 in the rib 22 of the hard vinyl chloride belt-like member 2, and the hard vinyl chloride belt-like member 2 is The rib 22 is manufactured by fusing the soft vinyl chloride sealing portion 4 together (see FIG. 2C).

一方、補強材入り帯状部材１によって更生管を製管する場合は、補強材入り帯状部材１を巻き重ねた輸送用ドラムを施工現場に輸送し、輸送用ドラムに巻き重ねられた補強材入り帯状部材１を引き出してマンホールに導くとともに、マンホールにおいて螺旋状に巻き回して更生管を製管する。具体的には、輸送用ドラムから引き出した補強材入り帯状部材１を基板２１の裏面側、すなわち、リブ２２を立設した側が外周面側に位置するように、既設管に臨んでマンホールに設置された製管機（図示せず）に供給することにより、図３（ａ），（ｂ）に示すように、隣接する補強材入り帯状部材１，１のうち、一方の補強材入り帯状部材１の接合凸部２３に他方の補強材入り帯状部材１の接合凹部２４を外側（先行する補強材入り帯状部材１の外周側）から嵌め込むことから、隣接する補強材入り帯状部材１，１を相互に接合して所定の管径の更生管を製管することができる。この際、先行する補強材入り帯状部材１の接合凸部２３を設けた基板２１の一側縁部に後続する補強材入り帯状部材１の段落ち部２５が配置される。   On the other hand, when a rehabilitated pipe is produced by the band member 1 with the reinforcing material, the transport drum around which the band member 1 with the reinforcing material is wound is transported to the construction site, and the band with the reinforcing material wound around the transportation drum is used. The member 1 is pulled out and guided to the manhole, and the rehabilitated tube is formed by spirally winding the manhole. Specifically, the band member 1 with the reinforcing material pulled out from the transport drum is installed in the manhole facing the existing pipe so that the back surface side of the substrate 21, that is, the side where the rib 22 is erected is located on the outer peripheral surface side. As shown in FIGS. 3 (a) and 3 (b), one of the adjacent reinforcing member-containing band-like members 1 and 1 is supplied to a pipe manufacturing machine (not shown). Since the bonding concave portion 24 of the other reinforcing material-containing band-shaped member 1 is fitted into one bonding convex portion 23 from the outside (the outer peripheral side of the preceding reinforcing-material-containing band-shaped member 1), the adjacent reinforcing material-containing band-shaped members 1, 1 Can be joined together to produce a rehabilitation pipe having a predetermined pipe diameter. At this time, a stepped-down portion 25 of the reinforcing material-containing band-shaped member 1 that follows the one side edge portion of the substrate 21 provided with the joining convex portion 23 of the preceding reinforcing material-containing band-shaped member 1 is disposed.

あるいは、輸送用ドラムから引き出した補強材入り帯状部材１を基板２１の裏面側、すなわち、リブ２２が立設された側が外周面側に位置するように、既設管に設置された製管機（図示せず）に供給することにより、図３（ａ），（ｂ）に示すように、隣接する補強材入り帯状部材１，１のうち、一方の補強材入り帯状部材１の接合凸部２３を他方の補強材入り帯状部材１の接合凹部２４に内側（先行する補強材入り帯状部材１の内周側）から嵌め込むことから、隣接する補強材入り帯状部材１，１を相互に接合して所定の管径の更生管を製管することができる。この際、後続する補強材入り帯状部材１の接合凸部２３を設けた基板２１の一側縁部が先行する補強材入り帯状部材１の段落ち部２５配置される。   Alternatively, a pipe-making machine installed on an existing pipe so that the reinforcing member-like band-shaped member 1 pulled out from the transport drum is located on the back surface side of the substrate 21, that is, the side on which the ribs 22 are erected is located on the outer peripheral surface side. 3 (a) and 3 (b), the joint protrusion 23 of one reinforcing material-containing band-shaped member 1 among the adjacent reinforcing material-containing band-shaped members 1 and 1 as shown in FIGS. Is inserted into the joint recess 24 of the other reinforcing material-containing band-shaped member 1 from the inner side (the inner peripheral side of the preceding reinforcing-material-containing band-shaped member 1), so that the adjacent reinforcing material-containing band-shaped members 1, 1 are bonded to each other. Thus, a rehabilitation pipe having a predetermined diameter can be produced. At this time, a stepped portion 25 of the preceding reinforcing material-containing band-shaped member 1 is disposed on one side edge portion of the substrate 21 provided with the joining convex portion 23 of the subsequent reinforcing material-containing band-shaped member 1.

このような更生管においては、螺旋状に巻き回された補強材入り帯状部材１に曲げが作用するが、硬質塩化ビニル製帯状部材２に対して軟質塩化ビニル製封閉部４は一定の面積を確保して一体に融着されており、両者が剥離することはない。すなわち、硬質塩化ビニル製帯状部材２のリブ２２から軟質塩化ビニル製封閉部４が剥離することを防止でき、金属製補強板材３が硬質塩化ビニル製帯状部材２のリブ２２から飛び出して外れることを確実に防止できる。しかも、更生管を構成する補強材入り帯状部材１は、剛性の大きな硬質塩化ビニルによって帯状部材が形成されており、リブ２２に埋設された金属製補強板材３と相俟ってより高剛性の特性を有している。   In such a rehabilitated pipe, bending acts on the band member 1 with a reinforcing material wound spirally, but the sealing portion 4 made of soft vinyl chloride has a certain area with respect to the band member 2 made of hard vinyl chloride. It is secured and fused together, and they do not peel off. That is, the soft vinyl chloride sealing part 4 can be prevented from peeling off from the ribs 22 of the hard vinyl chloride belt-like member 2, and the metal reinforcing plate 3 can jump out of the ribs 22 of the hard vinyl chloride belt-like member 2 and come off. It can be surely prevented. Moreover, the band-like member 1 with a reinforcing material constituting the rehabilitating pipe is formed with a band-like member made of rigid rigid vinyl chloride, and has a higher rigidity in combination with the metal reinforcing plate 3 embedded in the rib 22. It has characteristics.

また、隣接する補強材入り帯状部材１の接合部同士を互いに接合して更生管を製管した場合に、剛性の大きな硬質塩化ビニル製帯状部材２の接合部２３，２４の接合であり、接合部２３，２４の止水性能を確保することができる。また、更生管を製管するに際して、仮に接合部２３，２４が不完全に接合したとしても、補強材入り帯状部材１の接合部２３，２４の接合を解除できることから、元の補強材入り帯状部材１を巻き戻し、接合を解除した位置から更生管の製管作業を再開することができる。さらに、ポリエチレン製帯状部材を接合する溶融樹脂の成形機が不要となり、これまでの製管方法を作業環境に応じて選択することができる。例えば、製管機を既設管内に配置するとともに、既設管の軸心回りに公転させ、製管された更生管を残置させる製管方法を採用することも可能となり、製管距離が限定されることはない。また、断面円形以外の既設管であっても、既設管の形状に対応するガイドを設け、ガイドに沿って製管機を回転させることにより、既設管の形状に対応する更生管を製管することもできる。   In addition, when the joint portions of the adjacent band members 1 containing reinforcing materials are joined to each other to produce a rehabilitated pipe, the joint portions 23 and 24 of the rigid vinyl chloride belt-like member 2 having high rigidity are joined. The water stop performance of the parts 23 and 24 can be ensured. Further, when the rehabilitated pipe is manufactured, even if the joint portions 23 and 24 are incompletely joined, the joining of the joint portions 23 and 24 of the reinforcing material-containing band-like member 1 can be released, so that the original reinforcing material-containing belt-like shape is obtained. The member 1 can be rewound, and the remanufacturing work can be resumed from the position where the joining is released. Furthermore, a molding machine for molten resin that joins the polyethylene belt-like member is not required, and the conventional pipe making method can be selected according to the working environment. For example, it is possible to adopt a pipe making method in which the pipe making machine is arranged in the existing pipe, revolves around the axis of the existing pipe, and the renovated pipe that has been piped is left, and the pipe making distance is limited. There is nothing. Moreover, even if it is an existing pipe other than a circular cross section, a guide corresponding to the shape of the existing pipe is provided, and a renovated pipe corresponding to the shape of the existing pipe is manufactured by rotating the pipe making machine along the guide. You can also.

ところで、図４には、本発明の補強材入り帯状部材１の変形例が示されている。   By the way, FIG. 4 shows a modification of the band-like member 1 with the reinforcing material of the present invention.

この補強材入り帯状部材１は、硬質塩化ビニル製帯状部材２のリブ２２の頂部近傍に係止部２２１が形成されている。これにより、硬質塩化ビニル製帯状部材２のリブ２２の頂部及びその周縁部に軟質塩化ビニルを押出成形して軟質塩化ビニル製封閉部４を融着した場合、軟質塩化ビニル製封閉部４が、硬質塩化ビニル製帯状部材２のリブ２２の頂部近傍に形成された係止部２２１に係止される。このため、硬質塩化ビニル製帯状部材２の係止部２２１が軟質塩化ビニル製封閉部４の抜け出しに対してアンカーとして機能し、硬質塩化ビニル製帯状部材２からの軟質塩化ビニル製封閉部４の剥離をより確実に防止することができる。   This reinforcing member-containing band-shaped member 1 has a locking portion 221 formed in the vicinity of the top of the rib 22 of the rigid vinyl chloride band-shaped member 2. As a result, when the soft vinyl chloride sealing part 4 is fused by extruding soft vinyl chloride on the top of the rib 22 of the rigid vinyl chloride belt-like member 2 and the peripheral part thereof, the soft vinyl chloride sealing part 4 is The rigid vinyl chloride belt-shaped member 2 is locked by a locking portion 221 formed near the top of the rib 22. For this reason, the locking portion 221 of the hard vinyl chloride belt-like member 2 functions as an anchor against the withdrawal of the soft vinyl chloride sealing member 4, and the soft vinyl chloride sealing member 4 from the hard vinyl chloride belt-like member 2 Peeling can be prevented more reliably.

また、図５には、本発明の補強材入り帯状部材１の他の変形例が示されている。   Moreover, the other modification of the strip | belt-shaped member 1 with a reinforcing material of this invention is shown by FIG.

この補強材入り帯状部材１は、硬質塩化ビニル製帯状部材２のリブ２２の頂部その周縁部に一体に融着された軟質塩化ビニル製封閉部４が、金属製補強板材３の高さ方向の略中間部に対応する位置まで延長されている。これにより、硬質塩化ビニル製帯状部材２のリブ２２の頂部及びその周縁部に軟質塩化ビニルを押出成形して軟質塩化ビニル製封閉部４を融着した場合、硬質塩化ビニル製帯状部材２のリブ２２に対する軟質塩化ビニル製封閉部４の融着面積が増大し、硬質塩化ビニル製帯状部材２からの軟質塩化ビニル製封閉部４の剥離をより確実に防止することができる。   The reinforcing material-containing band-shaped member 1 has a soft vinyl chloride sealing portion 4 integrally fused to the peripheral portion of the top of the rib 22 of the hard vinyl chloride-shaped band member 2 in the height direction of the metal reinforcing plate 3. It extends to a position corresponding to the substantially middle portion. Thus, when soft vinyl chloride is extruded on the top of the rib 22 of the rigid vinyl chloride strip 2 and the peripheral edge thereof, and the soft vinyl chloride sealing portion 4 is fused, the rib of the rigid vinyl chloride strip 2 is obtained. Accordingly, the fusion-bonding area of the soft vinyl chloride sealing portion 4 with respect to 22 is increased, and the peeling of the soft vinyl chloride sealing portion 4 from the hard vinyl chloride belt-shaped member 2 can be more reliably prevented.

さらに、図６には、本発明の補強材入り帯状部材１のもう一つの変形例が示されている。   Furthermore, FIG. 6 shows another modification of the band-like member 1 with a reinforcing material of the present invention.
