Description

本発明は、管軸方向に沿って管の内面に並設した面材同士を、管心側から面材連接材を押圧して前記面材に係合させて面材同士を連接するために用いる面材連接装置に関するものである。 In the present invention, the face materials arranged side by side on the inner surface of the pipe along the pipe axis direction are engaged with the face material by pressing the face material connecting material from the pipe center side to connect the face materials to each other. It relates to a face material connecting device to be used.

従来、老朽化した下水道管等の既設管の補修構造として、既設管の内面を内張り材で全面的に覆う既設管の補修構造が数多く提案されている（例えば、特許文献１及び２参照。）。
このうち、特許文献１に記載のものは、組み立てることにより管状、角形又は馬蹄形の筒状体を構成する、内周面を構成する内面板と、該内面板の周縁に立設された外周板とをプラスチックによって一体に形成した流路施設修復用ブロック体を用いて施工されるものであり、また、特許文献２に記載のものは、既設管路内に、当該既設管路内面に略沿った中空骨組み状補強材が配置され、その補強材の内側に、既設管路の筒長方向並びに周方向にそれぞれ複数の面材が連続的に取り付けられて筒状に組み立てられているとともに、既設管路の筒長方向に隣接している面材同士は、互いの端面が当接した状態で、双方の面材に跨って配置された面材連接材により相互に連接されてなり、面材と既設管路内面との間に硬化性充填材が充填されてなるものである。 Conventionally, as a repair structure for an existing pipe such as an aged sewer pipe, many repair structures for an existing pipe in which the inner surface of the existing pipe is completely covered with a lining material have been proposed (see, for example, Patent Documents 1 and 2). ..
Of these, the ones described in Patent Document 1 are an inner surface plate constituting an inner peripheral surface which forms a tubular, square or horseshoe-shaped tubular body by assembling, and an outer peripheral plate erected on the peripheral edge of the inner surface plate. Is constructed using a block body for repairing a flow path facility integrally formed of plastic, and the one described in Patent Document 2 is substantially along the inner surface of the existing pipeline in the existing pipeline. A hollow skeleton-shaped reinforcing material is arranged, and a plurality of face materials are continuously attached to the inside of the reinforcing material in the tubular length direction and the circumferential direction of the existing pipeline to be assembled in a tubular shape, and are already installed. Face materials adjacent to each other in the tubular length direction of the pipeline are connected to each other by face material articulating materials arranged straddling both face materials in a state where their end faces are in contact with each other. A curable filler is filled between the pipe and the inner surface of the existing pipeline.

しかしながら、特許文献１に記載のものは、合成樹脂製のブロック体を使用するために高価な金型を必要とすることから、コストがかかり、また、数多くのブロック体の組み立てに多大な手間を要するものであり、また、特許文献２に記載のものは、既設管路の補修長が長くなるに従い、面材及び嵌合部材を筒長方向に連続したものを使用しようとする場合の輸送上又は製造設備上、製造現場における設置スペース等の問題を解決するものの、既設管路内に中空骨組み状の補強材を配置するのに補強材が多数の部材からなり補強材を既設管路内で組み立てるのに多大な手間を要し、また、面材の数も多くこれを同様に数の多い嵌合部材に係止するのに多大な手間を要するものとなっている。 However, the one described in Patent Document 1 requires an expensive mold for using a block body made of synthetic resin, which is costly and requires a great deal of labor for assembling a large number of block bodies. In addition, the one described in Patent Document 2 is for transportation when it is intended to use a face material and a fitting member continuous in the cylinder length direction as the repair length of the existing pipeline becomes longer. Or, although the problem of installation space at the manufacturing site is solved due to the manufacturing equipment, the reinforcing material is composed of a large number of members to arrange the hollow frame-shaped reinforcing material in the existing pipeline, and the reinforcing material is provided in the existing pipeline. It takes a lot of time and effort to assemble, and it takes a lot of time and effort to lock the number of face materials to the similarly large number of fitting members.

一方、このような実情に鑑み、経済的な部材を用い、その組み立ての手間を省いて設置作業を簡便化し、かつ、作業完了後においても長期に亘って耐久性のある既設管の補修構造として、既設管の内周面の周方向に沿って、管軸方向に所定の間隔をあけて配設した剛性リングと、これら剛性リングの内側に跨るように管軸方向に、剛性リングの周方向に所定の間隔をあけて配設した既設管の中心側に所定の間隔をあけて形成した切欠きを有する剛性直材と、該剛性直材の切欠きに対応する突条を有する帯状の合成樹脂製面材とからなり、前記合成樹脂製面材の突条を剛性直材の切欠きに嵌着することにより、合成樹脂製面材を既設管の内周面の周方向に沿って、かつ、管軸方向に隙間なく順次配設し、既設管と合成樹脂製面材との間に生じる空隙に硬化性充填材を充填したものも提案されている（例えば、特許文献３参照。）が、合成樹脂製面材が既設管の内周面の周方向に沿って配設されるものであるため、面材を管軸方向に凹凸を生じないように精度高く配設することができず、既設管路の補修長が長くなるに従い、面材の配設に手数がかかるという問題があった。 On the other hand, in view of such a situation, as an existing pipe repair structure that uses economical members, saves the trouble of assembling the members, simplifies the installation work, and is durable for a long period of time even after the work is completed. , Rigid rings arranged at predetermined intervals in the pipe axial direction along the circumferential direction of the inner peripheral surface of the existing pipe, and the circumferential direction of the rigid ring in the pipe axial direction so as to straddle the inside of these rigid rings. A rigid straight material having notches formed at a predetermined interval on the center side of an existing pipe arranged at a predetermined interval, and a strip-shaped composite having a ridge corresponding to the notch of the rigid straight material. It is composed of a resin face material, and by fitting the ridges of the synthetic resin face material into the notch of the rigid straight material, the synthetic resin face material is fitted along the circumferential direction of the inner peripheral surface of the existing pipe. Further, it has been proposed that the pipes are sequentially arranged in the axial direction of the pipe without a gap, and the gap formed between the existing pipe and the synthetic resin surface material is filled with a curable filler (see, for example, Patent Document 3). However, since the synthetic resin face material is arranged along the circumferential direction of the inner peripheral surface of the existing pipe, the face material can be arranged with high accuracy so as not to cause unevenness in the pipe axial direction. However, as the repair length of the existing pipeline becomes longer, there is a problem that it takes time and effort to arrange the face material.

このような実情に鑑みて、本件出願人は、先に、面材の設置作業を簡便化し、かつ、作業完了後においても長期に亘って耐久性のある面材及びその面材を用いた管の内層構造を提案した（特許文献４参照。）。
この面材を用いた管の内層構造は、図９（ａ）〜（ｃ）に示すように、幅方向に並設した帯状の面材Ｍ１同士を、各面材Ｍ１の幅方向の端部に形成された溝１１１内に形成した面材嵌合爪１１２と、両方の面材Ｍ１の幅方向の端部に跨って配設される面材連接材Ｍ２に平行に形成された突条１２１に対向して形成した面材連接材嵌合爪１２２とをそれぞれ嵌合させて連接する構造からなるものである。
しかしながら、この連接構造の場合、各面材Ｍ１の面材嵌合爪１１２と、面材連接材Ｍ２の面材連接材嵌合爪１２２とをそれぞれ嵌合させて面材Ｍ１同士を連接する作業に手数がかかるとともに、面材嵌合爪１１２と面材連接材嵌合爪１２２との嵌合作業の確実性が担保しにくいという問題があった。 In view of these circumstances, the applicant has first simplified the installation work of the face material, and has a face material that is durable for a long period of time even after the work is completed, and a pipe using the face material. (See Patent Document 4).
As shown in FIGS. 9A to 9C, the inner layer structure of the pipe using this face material is such that the strip-shaped face materials M1 arranged side by side in the width direction are arranged at the end of each face material M1 in the width direction. The ridge 121 formed in parallel with the face material fitting claw 112 formed in the groove 111 formed in the above and the face material connecting material M2 arranged across the widthwise ends of both face materials M1. It has a structure in which the face material connecting material fitting claws 122 formed so as to face each other are fitted and connected to each other.
However, in the case of this articulated structure, the work of mating the face material fitting claw 112 of each face material M1 and the face material articulating material fitting claw 122 of the face material articulating material M2 to connect the face materials M1 to each other. In addition to the trouble, it is difficult to ensure the certainty of the fitting work between the face material fitting claw 112 and the face material connecting material fitting claw 122.

そして、この嵌合爪を嵌合させて面材同士を連接する構造のものが有する問題点を解決するため、本件出願人は、嵌合爪同士を確実に嵌合させながら、面材同士を簡易に連接することができるようにした面材の連接用スライド治具（押圧係合操作部）を提案した（特許文献５参照。）。 Then, in order to solve the problem of the structure in which the fitting claws are fitted and the face materials are connected to each other, the applicant of the present application applies the facing materials to each other while securely fitting the fitting claws to each other. We have proposed a slide jig (pressing engagement operation unit) for connecting face materials that can be easily connected (see Patent Document 5).

図１〜図７に、本発明の面材連接装置の一実施例を示す。
この面材連接装置１は、管軸方向に沿って管Ｐの内面に並設した面材Ｍ１同士を、管心側から面材連接材Ｍ２を押圧して面材Ｍ１に係合させて面材Ｍ１同士を連接するために用いる面材連接装置１であって、管Ｐ内に固定する固定部２と、管心側から管外周側方向に面材連接材Ｍ２を押圧して面材Ｍ１に係合させて面材Ｍ１同士を連接する押さえ部３３を具備した押圧係合操作部３と、押圧係合操作部３を固定部２側に牽引する牽引部４と、面材Ｍ１の牽引部４側の端縁に当接して、面材Ｍ１の移動を阻止する当接支持部５とを有する。 1 to 7 show an embodiment of the face material connecting device of the present invention.
In this face material connecting device 1, the face materials M1 arranged side by side on the inner surface of the pipe P along the pipe axis direction are engaged with the face material M1 by pressing the face material connecting material M2 from the pipe center side. A face material connecting device 1 used for connecting members M1 to each other, in which a fixing portion 2 fixed in the pipe P and a face material connecting material M2 are pressed from the pipe center side toward the outer periphery of the pipe to press the face material M1.

Further, as the fixing mechanism of the fixing portion 2, in addition to the holding mechanism, any fixing mechanism such as a tensioning mechanism capable of fixing the face material connecting device 1 in the pipe P can be adopted.

押圧係合操作部３には、本件出願人が特許文献５において提案した面材の連接用スライド治具を適用することができる。
この押圧係合操作部３は、図９（ａ）〜（ｃ）に示すように、幅方向に並設した帯状の面材Ｍ１同士を、各面材Ｍ１の幅方向の端部に形成された溝１１１内に形成した面材嵌合爪１１２と、両方の面材Ｍ１の幅方向の端部に跨って配設される面材連接材Ｍ２に平行に形成された突条１２１に対向して形成した面材連接材嵌合爪１２２とをそれぞれ嵌合させて連接するために用いられるものであって、面材Ｍ１の溝１１１内に挿入される支持部３１と、面材連接材Ｍ２の平行に形成された突条１２１間に挿入される突条ガイド部３２と、面材連接材Ｍ２の表面を押圧する押さえ部３３とを、この順に接続部３４を介して一体に備え、支持部３１を、図６（ａ）に矢印で示す押圧係合操作部３のスライド方向の前方に向けて接続部３４から延設させるとともに、突条ガイド部３２及び押さえ部３３を押圧係合操作部３のスライド方向の後方に向けて接続部から延設させるようにしたものである。 A slide jig for connecting face materials proposed by the applicant in Patent Document 5 can be applied to the pressing engagement operation unit 3.
As shown in FIGS. 9A to 9C, the pressing engagement operation portion 3 is formed by forming strip-shaped face members M1 arranged side by side in the width direction at the end portion of each face member M1 in the width direction. Facing the face material fitting claw 112 formed in the groove 111 and the ridge 121 formed parallel to the face material connecting material M2 arranged across the widthwise ends of both face materials M1. It is used for fitting and connecting the face material connecting material fitting claws 122 formed in the above direction, and the support portion 31 inserted into the groove 111 of the face material M1 and the face material connecting material M2. The ridge guide portion 32 inserted between the ridges 121 formed in parallel with each other and the pressing portion 33 for pressing the surface of the face material connecting member M2 are integrally provided and supported in this order via the connecting portion 34. The portion 31 is extended from the connecting portion 34 toward the front in the sliding direction of the pressing engagement operating portion 3 indicated by the arrow in FIG. 6A, and the ridge guide portion 32 and the pressing portion 33 are pressed and engaged. The portion 3 is extended from the connecting portion toward the rear in the sliding direction.

ここで、面材連接材Ｍ２に平行に形成される突条１２１は、互いに一定の間隔をあけて形成されるようにする限りにおいて、図９（ａ）に示すように、面材連接材Ｍ２を構成する表面材１２０に対して、垂直に形成するほか、図９（ｂ）及び（ｃ）に示すように、傾斜させて形成することができる。 Here, as long as the ridges 121 formed in parallel with the face material connecting material M2 are formed at regular intervals from each other, as shown in FIG. 9A, the face material connecting material M2 In addition to being formed perpendicular to the surface material 120 constituting the above, it can be formed at an angle as shown in FIGS. 9 (b) and 9 (c).

そして、この押圧係合操作部３は、スライド方向にスライドさせた場合に面材連接材Ｍ２が回転部材３３ａ、３３ｂ、３３ｃによって順次下方へ押されるようになっている。すなわち、図６（ａ）の進行方向の後方に行くに従い、回転部材３３ａ、３３ｂ、３３ｃが上部位置から下部位置に順次位置をずらせて設けるように構成されている。
これにより、押さえ部３３の面材連接材Ｍ２への摩擦抵抗を少なくして、押圧係合操作部３のスライドを円滑に行うようにすることができ、面材連接材Ｍ２が下方へ押されるようにする。 When the pressing engagement operation unit 3 is slid in the sliding direction, the face material connecting member M2 is sequentially pushed downward by the rotating members 33a, 33b, 33c. That is, the rotating members 33a, 33b, and 33c are configured to be provided so as to be sequentially shifted from the upper position to the lower position toward the rear in the traveling direction of FIG. 6A.
As a result, the frictional resistance of the pressing portion 33 to the face material connecting material M2 can be reduced so that the pressing engagement operating portion 3 can be smoothly slid, and the face material connecting material M2 is pushed downward. To do so.

また、突条ガイド部３２は、面材連接材Ｍ２の突条１２１の位置を安定して制御するためのもので、この突条ガイド部３２は、押圧係合操作部３のスライド方向の後方に向けて、面材Ｍ１の幅方向の端部に形成された溝１１１内に入り込む方向に傾斜して設けるようにしている。
これにより、面材連接材Ｍ２の突条１２１を、押圧係合操作部３のスライドに合わせて、面材Ｍ１の幅方向の端部に形成された溝１１１内に引き込むことができる。 Further, the ridge guide portion 32 is for stably controlling the position of the ridge 121 of the face material connecting member M2, and the ridge guide portion 32 is rearward in the slide direction of the pressing engagement operation portion 3. The face material M1 is provided so as to be inclined in the direction of entering the groove 111 formed at the end portion in the width direction.
As a result, the ridge 121 of the face material connecting member M2 can be pulled into the groove 111 formed at the end portion in the width direction of the face material M1 in accordance with the slide of the pressing engagement operation unit 3.

また、突条ガイド部３２は、面材連接材Ｍ２の２つの突条１２１間の間隔を押し広げるように制御するように形成されている。具体的には、突条ガイド部３２は、押圧係合操作部３のスライド方向の後方に向けて、先割れ状態に拡開して形成されており、突条ガイド部３２の先割れした部分の間に両方の面材Ｍ１に形成された面材嵌合爪１１２が入り込むようにしている。
