Description

本発明は、既設の現場打ちされた側溝（例えば、コンクリート製Ｕ字型側溝）を新設同様に再生するために用いられる側溝再生用構造体の製造装置に関する。 The present invention relates to an apparatus for manufacturing a side groove regenerating structure used for regenerating an existing on-site side groove (for example, a concrete U-shaped side groove) in the same manner as newly installed.

従来、既設のコンクリート製Ｕ字型側溝において、その経年変化に伴う老朽化（劣化）が進んだ場合には、現場打ちされたＵ字型側溝全体を掘り出して除去した後、新たなＵ字型側溝ブロックに取り替えるといった改修工法が採用されている。しかし、かかる改修工法では、その工事期間中、バイパス路（迂回路）を設けて、その改修箇所における側溝機能を確保しなければならず、そのための手間や時間がかかるため、工事期間の短縮化や工事費用の低コスト化には一定の限界があった。 Conventionally, in the existing concrete U-shaped side gutter, when aging (deterioration) due to aging has progressed, after excavating and removing the entire U-shaped side gutter that has been struck on site, a new U-shaped side gutter is removed. A refurbishment method, such as replacing with a gutter block, is adopted. However, in such a renovation method, it is necessary to provide a bypass (detour) during the construction period to ensure the function of the gutter at the refurbishment point, and it takes time and labor to do so, shortening the construction period. There were certain limits to lowering construction costs.

ここで、コンクリート製Ｕ字型側溝のうち、老朽化（劣化）が進み易い箇所について考察すると、当該箇所としては、車両通行時の負荷並びに振動による影響、或いは、風雨に直接さらされることによる風化などの影響を直接受け易い箇所、即ち、当該Ｕ字型側溝の上部領域にあることが判明した。 Here, considering the portion of the concrete U-shaped side gutter that is prone to aging (deterioration), the location is affected by the load and vibration during vehicle traffic or weathering by direct exposure to wind and rain. It was found that it is in a place that is directly affected by the above-mentioned, that is, in the upper region of the U-shaped side groove.

そこで、現在、コンクリート製Ｕ字型側溝の改修方法として、既存の蓋部材（上蓋、側溝蓋）の撤去と共に、老朽化（劣化）した既設のＵ字型側溝の上部領域のみを切断若しくはハツリにより除去し、その除去後に残存した既設側溝の切断面（ハツリ面）上に、グレーチング蓋（例えば、鋼材を格子状に組んだ溝蓋）やコンクリート蓋などの各種の蓋部材を設置可能な側溝再生用構造体（特許文献１では、コンクリート蓋体と称する）を新設する技術が提案されている（特許文献１参照）。 Therefore, as a method of repairing the concrete U-shaped side groove, the existing lid member (upper cover, side groove cover) is removed and only the upper region of the existing U-shaped side groove that has been aged (deteriorated) is cut or scraped. Side groove regeneration that can be installed with various lid members such as grating lids (for example, groove lids in which steel materials are assembled in a lattice pattern) and concrete lids on the cut surfaces (chip surfaces) of existing side grooves that remain after removal A technique for newly providing a structural body (referred to as a concrete lid in Patent Document 1) has been proposed (see Patent Document 1).

ところで、既設のＵ字型側溝は、その使用目的（用途）や使用環境に応じた形態で現場打ちされるため、その形態に合わせて、上記した側溝再生用構造体を設計して製造する必要がある。この場合、側溝再生用構造体の製造方法としては、例えば、そのＵ字型側溝の形態に対応させた金型を用意し、これにコンクリートを流し込むことで、当該Ｕ字型側溝の形態に合った側溝再生用構造体を成形する方法を想定することができる。 By the way, since the existing U-shaped side groove is hit in the field in a form according to its intended use (use) and usage environment, it is necessary to design and manufacture the above-mentioned side groove recycling structure according to the form. There is. In this case, as a method of manufacturing the structure for reclamation of the side groove, for example, a mold corresponding to the shape of the U-shaped side groove is prepared, and concrete is poured into this, so that the shape of the U-shaped side groove is matched. It is possible to envisage a method for forming a side groove regenerating structure.

しかし、かかる方法では、Ｕ字型側溝の形態毎に金型を個別に用意しなければならず、当該Ｕ字型側溝の形態が多岐に亘っているような場合には、これに応じて多数の金型が必要となり、そうなると、側溝再生用構造体の製造方法に要するコストが大幅に上昇してしまう。また、側溝再生用構造体は、比較的大型であるため、これに伴って金型も大型化せざるを得ず、上記した多数の金型を用意したような場合には、これに応じて多数の金型を保管するための広いスペースを確保することが必要となり、そうなると、当該金型の管理に要する人件費や管理（保管）費などが別途かかるため、側溝再生用構造体の製造方法に要するコストがさらに上昇してしまう。 However, in such a method, it is necessary to prepare a mold individually for each form of the U-shaped side groove. Therefore, the cost required for the manufacturing method of the structure for regenerating a side groove is significantly increased. In addition, since the structure for reclamation of the side groove is relatively large, the mold must be enlarged along with this, and when a large number of the above-mentioned molds are prepared, It is necessary to secure a large space for storing a large number of molds. If this happens, labor costs and management (storage) costs required for managing the molds are separately required. Cost further increases.

この場合、１台の製造装置だけで、多岐に亘るＵ字型側溝の各種形態に応じた側溝再生用構造体を製造することができれば、側溝再生用構造体の製造コストを大幅に低減させることができるだけでなく、保管スペースも製造装置１台分だけで済むため、そのための人件費や管理（保管）費なども低く抑えることができる。しかしながら、現在このような製造装置は知られていない。 In this case, if it is possible to manufacture a structure for regenerating a side groove corresponding to various forms of a wide variety of U-shaped side grooves with only one manufacturing apparatus, the manufacturing cost of the structure for regenerating a side groove can be greatly reduced. In addition, since only a single manufacturing device is required for storage space, personnel costs and management (storage) costs can be kept low. However, such a manufacturing apparatus is not known at present.

本発明の目的は、１台の製造装置だけで、多岐に亘るＵ字型側溝の形態に応じた側溝再生用構造体を低コストで製造することが可能な技術を提供することにある。 The objective of this invention is providing the technique which can manufacture the structure for side groove reproduction | regeneration according to the form of a wide U-shaped side groove only by one manufacturing apparatus at low cost.

以下、本発明の一実施形態に係る側溝再生用構造体の製造装置について、添付図面を参照して説明する。
本実施形態において、側溝再生用構造体としては、既設の現場打ちされたコンクリート製Ｕ字型側溝（以下、既設側溝という）の上部領域を切断若しくはハツリ（例えば、削り取ったり、そぎ落とす作業）により除去した後、その切断面（ハツリ面）上に設置することで、当該側溝を新設同様に再生するためのものを想定する。 Hereinafter, an apparatus for manufacturing a structure for reproducing a side groove according to an embodiment of the present invention will be described with reference to the accompanying drawings.
In the present embodiment, as the side groove regenerating structure, the upper region of the existing concrete U-shaped side groove (hereinafter referred to as the existing side groove) that has been cast in the field is cut or scraped (for example, scraping or scraping off). After removal, it is assumed that the side groove is regenerated in the same manner as newly installed by installing it on the cut surface (chip surface).

『側溝再生用構造体２について』
図１(ａ)に示すように、本実施形態の側溝再生用構造体２は、図示しない既設側溝の切断面（ハツリ面）上に設置可能な形状を成す枠本体４を備えている。枠本体４の形状や大きさについては、例えば、既設側溝（上部領域）の形状や大きさ、或いは、側溝再生用構造体２の使用目的や使用環境に応じて設定されるため、ここでは特に限定しない。図面には一例として、外面が直方体形状を成すと共に、その中央を矩形状に刳り貫いて形成した刳り貫き部４ｐを有する枠本体４が示されており、当該枠本体４の表面４ａと裏面４ｂとは互いに平行に構成されている。 “About the structure 2 for reclaiming the side groove”
As shown in FIG. 1 (a), the side groove regenerating structure 2 of the present embodiment includes a frame body 4 having a shape that can be installed on a cut surface (chip surface) of an existing side groove (not shown). The shape and size of the frame body 4 are set according to, for example, the shape and size of the existing side groove (upper region) or the usage purpose and usage environment of the side groove reproduction structure 2. Not limited. As an example, the drawing shows a frame main body 4 having an outer surface having a rectangular parallelepiped shape and having a through-hole portion 4p formed by piercing the center in a rectangular shape. The front surface 4a and the back surface 4b of the frame main body 4 are shown. Are configured parallel to each other.

刳り貫き部４ｐの内面（側溝再生用構造体２の内面とも言う）は、側溝再生用構造体２の使用目的や使用環境に応じて、所定の輪郭を成して構成されている。本実施形態において、刳り貫き部４ｐの内面には、例えばグレーチング蓋やコンクリート蓋などの各種の蓋部材を設置可能な蓋部材設置部６が互いに平行な位置関係で対向させて設けられている。なお、図１(ａ)には、一方の蓋部材設置部６のみが示されている。 The inner surface of the punched-through portion 4p (also referred to as the inner surface of the side groove regenerating structure 2) is configured with a predetermined contour depending on the purpose of use and the usage environment of the side groove regenerating structure 2. In the present embodiment, a lid member installation portion 6 on which various lid members such as a grating lid and a concrete lid can be installed is provided on the inner surface of the punching portion 4p so as to face each other in a parallel positional relationship. In FIG. 1A, only one lid member installation portion 6 is shown.

双方の蓋部材設置部６は、刳り貫き部４ｐの内面において、その枠本体４の裏面４ｂ寄りの部位を他の部位よりも突出させて構成されていると共に、当該枠本体４に沿って互いに平行な位置関係で対向して延在されている。図１(ａ)には一例として、枠本体４の表面４ａ及び裏面４ｂと平行に延在する設置平面６ａと、設置平面６ａから下り勾配を成して連続した設置傾斜面６ｂとを有した蓋部材設置部６が示されている。 Both lid member installation portions 6 are configured such that a portion near the back surface 4b of the frame main body 4 protrudes from the other portion on the inner surface of the punched-through portion 4p, and along the frame main body 4 each other. They extend opposite to each other in a parallel positional relationship. As an example, FIG. 1 (a) has an installation plane 6a extending parallel to the front surface 4a and the back surface 4b of the frame body 4, and an installation inclined surface 6b that is continuous from the installation plane 6a with a downward slope. The lid member installation part 6 is shown.

この場合、刳り貫き部４ｐの内面における各蓋部材設置部６の位置は、当該蓋部材設置部６上に設置される各種の蓋部材の厚さ（高さ）に応じて設定されるため、ここでは特に限定しない。なお、各蓋部材設置部６は、蓋部材を設置可能であれば、その形状について特に限定されるものではない。 In this case, since the position of each lid member installation portion 6 on the inner surface of the punching portion 4p is set according to the thickness (height) of various lid members installed on the lid member installation portion 6, There is no particular limitation here. In addition, each lid member installation part 6 will not be specifically limited about the shape, if a lid member can be installed.

また、枠本体４には、蓋部材設置部６から枠本体４の裏面４ｂに亘って貫通し、枠本体４の裏面４ｂと既設側溝の切断面（ハツリ面）との間に連結材料（図示しない）を注入するための注入孔８が形成されている。なお、注入孔８の大きさや形状、或いは、個数については、例えば、枠本体４（蓋部材設置部６）の形状や大きさ、或いは、側溝再生用構造体２の使用目的や使用環境に応じて設定されるため、ここでは特に限定しない。図面では一例として、各蓋部材設置部６を所定間隔で一部切り欠いた切欠部６ｐを２箇所形成し、各切欠部６ｐにおいて、当該蓋部材設置部６から枠本体４の裏面４ｂに亘って貫通させた注入孔８が１個ずつ形成されている。 The frame body 4 penetrates from the lid member installation portion 6 to the back surface 4b of the frame body 4, and a connecting material (illustrated) is formed between the back surface 4b of the frame body 4 and the cut surface (scratch surface) of the existing side groove. An injection hole 8 for injecting (not) is formed. The size, shape, or number of the injection holes 8 depends on, for example, the shape and size of the frame body 4 (lid member installation portion 6), or the purpose of use and the environment of use of the side groove regeneration structure 2. Therefore, there is no particular limitation here. In the drawing, as an example, two notch portions 6p in which each lid member installation portion 6 is partially cut out at a predetermined interval are formed, and each of the notch portions 6p extends from the lid member installation portion 6 to the back surface 4b of the frame body 4. One injection hole 8 penetrating each other is formed one by one.

更に、本体枠４には、その長さ（長手）方向両側に、それぞれ一対の穿孔１０が形成されており、ここに既存の吊り下げ装置（図示しない）の吊り下げ治具を挿入して牽引することで、例えば図１(ｂ)に示すように、側溝再生用構造体２（本体枠４）を、既設側溝の切断面（ハツリ面）Ｐｍ上に安全確実に設置することができる。この場合、各穿孔１０に代えて、上記した各注入孔８に吊り下げ治具を挿入して牽引するようにしてもよい。これにより、当該側溝を新設同様に再生することが可能となる。なお、各穿孔１０は、後述する製造装置により成形材を固化させて完成品としての側溝再生用構造体２を成形した後、当該完成品を脱型する際に用いられる脱型用治具（図示しない）を挿入する孔としても併用することができる。 Further, the body frame 4 is formed with a pair of perforations 10 on both sides in the length (longitudinal) direction, and a suspension jig of an existing suspension device (not shown) is inserted here to pull it. By doing so, for example, as shown in FIG. 1 (b), the side groove regenerating structure 2 (main body frame 4) can be safely and reliably installed on the cut surface (scratch surface) Pm of the existing side groove. In this case, instead of each of the perforations 10, a suspension jig may be inserted into the above-described injection holes 8 and pulled. This makes it possible to regenerate the side groove in the same manner as newly installed. Note that each of the perforations 10 is formed by a molding apparatus that will be described later to solidify a molding material to form a side groove regeneration structure 2 as a finished product, and then a demolding jig ( (Not shown) can be used together as a hole for inserting.

ここで、側溝再生用構造体２（本体枠４）の表面４ａには、例えば滑り止め構造や水捌け構造を施すことが好ましい。図１(ａ),(ｂ)には、滑り止め構造の一例として、本体枠４の長さ（長手）方向両側にそれぞれ複数の交差溝１２が形成されていると共に、水捌け構造の一例として、本体枠４の長さ（長手）方向両側にそれぞれ２本の水路１４が形成されている。なお、これら各交差溝１２及び各水路１４は、本体枠４の長さ（長手）方向両側の表面４ａを他の部位よりも一部窪ませて形成されている。 Here, it is preferable to provide, for example, a non-slip structure or a water draining structure on the surface 4a of the side groove regeneration structure 2 (main body frame 4). In FIGS. 1A and 1B, as an example of the anti-slip structure, a plurality of cross grooves 12 are formed on both sides in the length (longitudinal) direction of the main body frame 4, and as an example of a water draining structure, Two water channels 14 are formed on both sides in the length (longitudinal) direction of the main body frame 4. Each cross groove 12 and each water channel 14 is formed by partially denting the surface 4a on both sides in the length (longitudinal) direction of the main body frame 4 from other portions.

また、各水路１４は、本体枠４の長さ（長手）方向に沿って延出しており、その一端は刳り貫き部４ｐに連通し、その他端は当該本体枠４の端面を貫通している。この場合、複数の側溝再生用構造体２（本体枠４）を既設側溝上に設置した状態において、隣り合う側溝再生用構造体２（本体枠４）同士の各水路１４が相互に連続する（図１(ｂ)参照）。これにより、当該溝再生用構造体２（本体枠４）上に流れ込んだ例えば雨水などを、各水路１４を介して効率よく確実に側溝内に排水させることができる。この結果、上記した交差溝１２（滑り止め構造）との相乗効果により、当該溝再生用構造体２（本体枠４）上を安全に往来・走行することが可能となる。 In addition, each water channel 14 extends along the length (longitudinal) direction of the main body frame 4, one end of which communicates with the penetrating portion 4 p and the other end passes through the end surface of the main body frame 4. . In this case, in the state where the plurality of side groove regeneration structures 2 (main body frame 4) are installed on the existing side grooves, the water channels 14 between the adjacent side groove regeneration structures 2 (main body frame 4) are continuous with each other ( (Refer FIG.1 (b)). Thereby, for example, rainwater or the like that has flowed onto the groove regenerating structure 2 (main body frame 4) can be efficiently and reliably drained into the side grooves via the water channels 14. As a result, due to a synergistic effect with the above-described cross groove 12 (anti-slip structure), it is possible to safely travel and travel on the groove regeneration structure 2 (main body frame 4).

The shape is formed along (coincident with) the inner surface contour.

具体的には、中子ユニット１６は、刳り貫き部４ｐの内面を成形するために矩形状に連続して立ち上げられた内面成形部１６ａと、刳り貫き部４ｐの内面に設けられた各蓋部材設置部６の輪郭形状に沿うように窪ませた設置部用凹部１６ｂとを備えており、設置部用凹部１６ｂには、蓋部材設置部６の各切欠部６ｐに形成された注入孔８を成形するための注入孔用治具１６ｃが着脱自在に取り付けられている。なお、内面成形部１６ａは、完成品の脱型をし易くすべく、脱型方向に向って先細り状の勾配を付して構成することが好ましい。 Specifically, the core unit 16 includes an inner surface forming portion 16a that is continuously raised in a rectangular shape to form the inner surface of the punched through portion 4p, and each lid provided on the inner surface of the punched through portion 4p. An installation portion recess 16b that is recessed along the contour shape of the member installation portion 6 is provided. The installation portion recess 16b has an injection hole 8 formed in each notch 6p of the lid member installation portion 6. An injection hole jig 16c for forming the mold is detachably attached. The inner surface molding portion 16a is preferably configured with a taper-like gradient toward the demolding direction so that the finished product can be easily demolded.

また、型枠ユニット１８の内面は、直方体形状を成す枠本体４の外面（図１参照）を後述する製造プロセスによって一体成形させるべく、表面４ａと裏面４ｂとが互いに平行に構成された当該外面輪郭に沿った（一致した）形状を成して構成されている。 In addition, the inner surface of the mold unit 18 has an outer surface in which the front surface 4a and the rear surface 4b are formed in parallel with each other so that the outer surface of the frame body 4 having a rectangular parallelepiped shape (see FIG. 1) is integrally formed by a manufacturing process described later. It is configured to have a shape that matches (matches) the contour.

具体的には、型枠ユニット１８は、中子ユニット１６を挟んでその両側に互いに対向させて平行に設けられ、当該中子ユニット１６に対して相対的に接近或いは離間させることで、完成品としての側溝再生用構造体２の幅を規定することが可能な一対の幅規定用型枠２０,２２と、これら一対の幅規定用型枠２０,２２を中子ユニット１６に対して所定位置に位置決めする位置決め機構２４,２６と、中子ユニット１６の周囲に沿って水平方向に延在させた平坦状の型枠ベース２８とを備えている。 Specifically, the mold unit 18 is provided in parallel on both sides of the core unit 16 so as to be opposed to each other, and is moved toward or away from the core unit 16 to complete the finished product. A pair of width defining molds 20 and 22 capable of defining the width of the side groove regenerating structure 2 as a pair, and the pair of width defining molds 20 and 22 with respect to the core unit 16 at predetermined positions. Positioning mechanisms 24 and 26, and a flat formwork base 28 extending in the horizontal direction along the periphery of the core unit 16.

一対の幅規定用型枠２０,２２は、それぞれ、型枠ベース２８上に沿ってスライド（移動）自在に構成配置されており、後述する製造プロセスにおいて、中子ユニット１６と型枠ユニット１８との間に投入された成形材Ｆｓ（図３〜図６参照）を漏れなく貯留させることができるように構成されている。 Each of the pair of width defining molds 20 and 22 is configured and slidable (movable) along the mold base 28. In the manufacturing process described later, the core unit 16 and the mold unit 18 The molding material Fs (see FIG. 3 to FIG. 6) that is put in between can be stored without leakage.

また、型枠ベース２８は、完成品としての側溝再生用構造体２（枠本体４）の表面４ａ（図１参照）の輪郭形状に一致させた外面形状を有して構成されている。本実施形態では一例として、側溝再生用構造体２（枠本体４）の表面４ａには、その長さ（長手）方向両側にそれぞれ複数の交差溝１２と２本の各水路１４が形成されている。 Further, the mold base 28 is configured to have an outer surface shape that matches the contour shape of the surface 4a (see FIG. 1) of the side groove reproducing structure 2 (frame body 4) as a finished product. In the present embodiment, as an example, a plurality of intersecting grooves 12 and two water channels 14 are formed on the surface 4a of the side groove regeneration structure 2 (frame body 4) on both sides in the length (longitudinal) direction. Yes.

このため、型枠ベース２８の外面は、当該各交差溝１２及び各水路１４を含めた枠本体４の表面４ａ（図１参照）を後述する製造プロセスによって一体成形させるべく、各交差溝１２及び各水路１４を含めた当該表面輪郭に沿った（一致した）形状を成して構成されている。即ち、型枠ベース２８の外面には、中子ユニット１６を挟んでその長さ（長手）方向両側に、各交差溝１２の表面輪郭に沿った（一致した）形状を成す複数の交差凸部２８ａと共に、各水路１４の表面輪郭に沿った（一致した）形状を成す２本の平行凸部２８ｂが構成されている。 Therefore, the outer surface of the mold base 28 is formed so that the surface 4a (see FIG. 1) of the frame body 4 including the cross grooves 12 and the water channels 14 is integrally formed by a manufacturing process described later. Each of the water channels 14 is configured to have a shape that matches (coincides with) the surface contour. That is, on the outer surface of the mold base 28, a plurality of intersecting convex portions having a shape along (coincident with) the surface contour of each intersecting groove 12 on both sides in the length (longitudinal) direction with the core unit 16 interposed therebetween. Along with 28a, two parallel convex portions 28b forming a shape along (coincident with) the surface contour of each water channel 14 are configured.

図２及び図３に示すように、一対の幅規定用型枠２０,２２のうち、一方側の幅規定用型枠２０を位置決めする位置決め機構２４は、一方側の幅規定用型枠２０を搭載した状態で、当該一方側の幅規定用型枠２０を中子ユニット１６に対して接近或いは離間させる方向に沿って移動可能なスライダ２４ａと、スライダ２４ａの中央部分を貫通させて形成され、当該スライダ２４ａの移動方向に沿って長孔状に延出させたガイド孔２４ｂと、ガイド孔２４ｂを通して型枠ベース２８に締結可能な締結治具２４ｃとを備えている。 As shown in FIGS. 2 and 3, the positioning mechanism 24 for positioning the width defining mold 20 on one side of the pair of width defining molds 20, 22 includes the width defining mold 20 on one side. In a mounted state, the width defining mold 20 on the one side is formed so as to be movable along a direction in which the width defining mold 20 approaches or separates from the core unit 16 and a central portion of the slider 24a is penetrated. A guide hole 24b that is elongated in the moving direction of the slider 24a and a fastening jig 24c that can be fastened to the mold base 28 through the guide hole 24b are provided.

なお、締結治具２４ｃとしては、例えばボルトやネジ等の既存のものを適用することができるが、図面には一例として、型枠ベース２８に形成されたボルト穴（図示しない）に螺合可能なボルトが示されている。 As the fastening jig 24c, for example, an existing one such as a bolt or a screw can be applied. However, as an example, the drawing can be screwed into a bolt hole (not shown) formed in the mold base 28. Bolts are shown.

かかる位置決め機構２４によれば、一方側の幅規定用型枠２０を搭載したスライダ２４ａを、締結治具２４ｃが通されたガイド孔２４ｂに沿って移動させた後、当該締結治具２４ｃをガイド孔２４ｂを通して型枠ベース２８に締結させることで、当該一方側の幅規定用型枠２０を中子ユニット１６に対して所定位置に位置決めすることができる。 According to the positioning mechanism 24, after the slider 24a on which the width defining mold 20 on one side is mounted is moved along the guide hole 24b through which the fastening jig 24c is passed, the fastening jig 24c is guided. By fastening to the mold base 28 through the hole 24b, the width defining mold 20 on the one side can be positioned at a predetermined position with respect to the core unit 16.

また、一対の幅規定用型枠２０,２２のうち、他方側の幅規定用型枠２２を位置決めする位置決め機構２６は、他方側の幅規定用型枠２２の外側であって且つ反中子ユニット６側に設けられ、型枠ベース２８に固定された固定型枠２６ａと、固定型枠２６ａと他方側の幅規定用型枠２２とを貫通して設けられ、当該他方側の幅規定用型枠２２を中子ユニット１６に対して接近或いは離間させる方向に沿って延出させたガイドシャフト２６ｂと、ガイドシャフト２６ｂを挿通可能な貫通孔（図示しない）が形成された複数の中空部材２６ｃと、ガイドシャフト２６ｂの両側に係合可能な係合治具２６ｄとを備えている。 In addition, the positioning mechanism 26 for positioning the width defining mold 22 on the other side of the pair of width defining molds 20 and 22 is outside the width defining mold 22 on the other side and is anti-core. A fixed mold 26 a provided on the unit 6 side and fixed to the mold base 28, and provided through the fixed mold 26 a and the width defining mold 22 on the other side, for defining the width on the other side. A plurality of hollow members 26c each formed with a guide shaft 26b extending along a direction in which the mold 22 approaches or separates from the core unit 16 and through holes (not shown) through which the guide shaft 26b can be inserted. And an engagement jig 26d that can be engaged with both sides of the guide shaft 26b.

なお、係合治具２６ｄの一例として、ガイドシャフト２６ｂの外周にネジを形成した場合、当該ネジに係合（螺合）可能なナットを係合治具２６ｄとして適用すればよい。この場合、ガイドシャフト２６ｂの基端側には、予め係合治具２６ｄを係合（螺合）して他方側の幅規定用型枠２２に対して脱落不能に取り付けておくことが好ましい。これにより、ガイドシャフト２６ｂの先端側から係合治具２６ｄを係合（螺合）させるだけで、各中空部材２６ｃをガイドシャフト２６ｂに沿って位置決め固定させることができる。 As an example of the engagement jig 26d, when a screw is formed on the outer periphery of the guide shaft 26b, a nut that can be engaged (screwed) with the screw may be applied as the engagement jig 26d. In this case, it is preferable that an engagement jig 26d is engaged (screwed) in advance with the base end side of the guide shaft 26b so that the guide shaft 26b cannot be detached from the width defining mold 22 on the other side. Thereby, each hollow member 26c can be positioned and fixed along the guide shaft 26b only by engaging (screwing) the engaging jig 26d from the distal end side of the guide shaft 26b.

かかる位置決め機構２６によれば、複数の中空部材２６ｃを固定型枠２６ａと他方側の幅規定用型枠２２との間に介在させることなく（図２及び図４参照）、或いは、少なくとも１つの中空部材２６ｃを固定型枠２６ａと他方側の幅規定用型枠２２との間に介在させた状態で（図５参照）、係合治具２６ｄをガイドシャフト２６ｂの両側に係合（螺合）させることで、当該他方側の幅規定用型枠２２を中子ユニット１６に対して所定位置に位置決めすることができる。即ち、固定型枠２６ａと他方側の幅規定用型枠２２との間に介在させる中空部材２６ｃの個数を増減変更するだけで、当該他方側の幅規定用型枠２２を中子ユニット１６に対して所定位置に位置決めすることができる。 According to the positioning mechanism 26, a plurality of hollow members 26c are not interposed between the fixed mold 26a and the width defining mold 22 on the other side (see FIGS. 2 and 4), or at least one With the hollow member 26c interposed between the fixed mold 26a and the width-defining mold 22 on the other side (see FIG. 5), the engaging jig 26d is engaged (screwed together) on both sides of the guide shaft 26b. ), The other width-defining mold 22 can be positioned at a predetermined position with respect to the core unit 16. That is, the width defining mold 22 on the other side can be changed to the core unit 16 simply by increasing or decreasing the number of hollow members 26c interposed between the fixed mold 26a and the width defining mold 22 on the other side. On the other hand, it can be positioned at a predetermined position.

この場合、中空部材２６ｃの形状や大きさ（例えば、長さ、太さ）、並びに、使用する個数については、例えば側溝再生用構造体２の形状や大きさ等に応じて設定されるため、ここでは特に限定しない。図面では一例として、互いに同一の大きさの中空円筒形状を成す中空部材２６ｃを２個用いて、中子ユニット１６に対する他方側の幅規定用型枠２２の位置決めを行う場合が示されている。 In this case, since the shape and size (for example, length, thickness) of the hollow member 26c and the number to be used are set according to the shape and size of the side groove reproducing structure 2, for example, There is no particular limitation here. In the drawing, as an example, the case where the other side width defining mold 22 is positioned with respect to the core unit 16 by using two hollow members 26c having a hollow cylindrical shape of the same size is shown.

更に、型枠ユニット１８は、中子ユニット１６を挟んで一対の幅規定用型枠２０,２２の両外側に隣接させ且つ互いに対向させると共に、当該一対の幅規定用型枠２０,２２を接近或いは離間させる方向に沿って互いに平行に延在させることで、完成品としての側溝再生用構造体２の長さを規定することが可能な一対の長さ規定用型枠３０,３２を備えている。 Further, the mold unit 18 is adjacent to and opposed to the outer sides of the pair of width defining molds 20 and 22 with the core unit 16 interposed therebetween, and the pair of width defining molds 20 and 22 are brought close to each other. Alternatively, a pair of length defining molds 30 and 32 that can define the length of the side groove reproducing structure 2 as a finished product by extending in parallel with each other along the separating direction are provided. Yes.

これら一対の長さ規定用型枠３０,３２は、それぞれ、中子ユニット１６に対向させた姿勢と、中子ユニット１６から後退させた姿勢とに転回可能に軸支されている。
ここで、一対の長さ規定用型枠３０,３２を中子ユニット１６に対向させた姿勢とは、図２(ａ)に示された姿勢であって、後述する製造プロセスにおいて、中子ユニット１６と型枠ユニット１８との間に投入された成形材Ｆｓ（図３〜図６参照）を漏れなく貯留させることができる姿勢をいう。 The pair of length-defining molds 30 and 32 are pivotally supported so as to be able to rotate between a posture facing the core unit 16 and a posture retracted from the core unit 16.
Here, the posture in which the pair of length-defining molds 30 and 32 are opposed to the core unit 16 is the posture shown in FIG. 2A, and in the manufacturing process described later, The posture which can store the molding material Fs (refer FIGS. 3-6) thrown between 16 and the formwork unit 18 without leaking is said.

型枠ユニット１８には、一対の長さ規定用型枠３０,３２を、成形材Ｆｓを漏れなく貯留させることができる姿勢（図２〜図６参照）に保持する保持機構が設けられている。保持機構は、一対の長さ規定用型枠３０,３２の一方側を、一方側の幅規定用型枠２０の両外側に隙間無く隣接させた状態に保持する一方側保持機構と、一対の長さ規定用型枠３０,３２の他方側を、他方側の幅規定用型枠２２の両外側に隙間無く隣接させた状態に保持する他方側保持機構とを備えて構成されている。 The mold unit 18 is provided with a holding mechanism that holds the pair of length-defining molds 30 and 32 in a posture (see FIGS. 2 to 6) that allows the molding material Fs to be stored without omission. . The holding mechanism includes a one-side holding mechanism that holds one side of the pair of length-defining molds 30 and 32 adjacent to both outer sides of the width-defining mold 20 on one side, and a pair of The other side holding mechanism is configured to hold the other side of the length-defining molds 30 and 32 so as to be adjacent to both outer sides of the width-defining mold 22 on the other side without any gap.

一方側保持機構は、一対の長さ規定用型枠３０,３２の一方側相互に掛け渡された１本の保持シャフト３４を有しており、保持シャフト３４は、その基端が一方の長さ規定用型枠３０（又は３２）に固定された回転操作部３６に着脱自在に支持され、その先端が他方の長さ規定用型枠３２（又は３０）に固定された受け部３８に抜け止めされた状態で着脱自在に支持されている。なお、回転操作部３６及び受け部３８は、一対の長さ規定用型枠３０,３２の一方側において、複数個所に亘って設けることが可能であるが、本実施形態では一例として、２箇所に回転操作部３６及び受け部３８が互いに平行に対向して設けられた場合を想定する。 The one-side holding mechanism has one holding shaft 34 that is stretched over one side of the pair of length-defining molds 30 and 32, and the holding shaft 34 has a base end that has one length. It is detachably supported by the rotation operation unit 36 fixed to the length defining mold 30 (or 32), and the tip thereof is pulled out to the receiving unit 38 fixed to the other length defining mold 32 (or 30). It is detachably supported in a stopped state. In addition, although the rotation operation part 36 and the receiving part 38 can be provided over several places in one side of a pair of length regulation molds 30 and 32, in this embodiment, two places are mentioned as an example. It is assumed that the rotary operation unit 36 and the receiving unit 38 are provided in parallel with each other.

この場合、保持シャフト３４の先端を受け部３８に挿通しつつ、回転操作部３６を操作して当該保持シャフト３４を矢印Ｓ方向に牽引すると、保持シャフト３４の先端に螺合したナット及び座金等がストッパ４０として機能し、これが受け部３８の外側端に圧接することで、当該保持シャフト３４は、受け部３８に抜け止めされた状態で支持される。このとき、保持シャフト３４を介して一対の長さ規定用型枠３０,３２の一方側に作用する引っ張り力によって、当該一対の長さ規定用型枠３０,３２の一方側が互いに引っ張られることで、一対の長さ規定用型枠３０,３２の一方側が、一方側の幅規定用型枠２０の両外側に隙間無く隣接させた状態に保持される。 In this case, when the rotation operation unit 36 is operated and the holding shaft 34 is pulled in the direction of the arrow S while being inserted into the receiving portion 38 while the tip of the holding shaft 34 is inserted, a nut, a washer and the like that are screwed into the tip of the holding shaft 34. Functions as a stopper 40, and is pressed against the outer end of the receiving portion 38, so that the holding shaft 34 is supported in a state of being prevented from coming off by the receiving portion 38. At this time, one side of the pair of length-defining molds 30, 32 is pulled with respect to each other by a pulling force acting on one side of the pair of length-defining molds 30, 32 via the holding shaft 34. The one side of the pair of length defining molds 30 and 32 is held in a state of being adjacent to both outer sides of the width defining mold 20 on one side with no gap.

また、他方側保持機構は、一対の長さ規定用型枠３０,３２の他方側に設けられた回転操作機構４２と、型枠ベース２８に固定された固定型枠２６ａの両側に設けられたフック機構４４とを有している。ここで、図４には他方側保持機構の一例が具体的に示されており、回転操作機構４２は、回転自在に支持された操作レバー４２ａと、操作レバー４２ａを操作することで突没可能に構成された係合片４２ｂとを備えていると共に、フック機構４４は、係合片４２ｂを引っ掛けた状態で保持することができるように構成されている。 The other side holding mechanism is provided on both sides of the rotation operation mechanism 42 provided on the other side of the pair of length defining molds 30 and 32 and the fixed mold 26 a fixed to the mold base 28. And a hook mechanism 44. Here, FIG. 4 specifically shows an example of the other side holding mechanism, and the rotation operation mechanism 42 can be protruded and retracted by operating the operation lever 42a rotatably supported and the operation lever 42a. The hook mechanism 44 is configured to be able to hold the engagement piece 42b in a hooked state.

この場合、回転操作機構４２（操作レバー４２ａ）を操作してその一部（即ち、係合片４２ｂ）をフック機構４２に係合させると、そのときの係合力により、一対の長さ規定用型枠３０,３２の他方側が固定型枠２６ａに引き寄せられることで、一対の長さ規定用型枠３０,３２の他方側が、他方側の幅規定用型枠２２の両外側に隙間無く隣接させた状態に保持される。 In this case, when a part of the rotation operation mechanism 42 (operation lever 42a) is engaged with the hook mechanism 42 (that is, the engagement piece 42b), the pair of length-defining is determined by the engagement force at that time. By pulling the other side of the molds 30 and 32 to the fixed mold 26 a, the other side of the pair of length defining molds 30 and 32 is adjacent to both outer sides of the width defining mold 22 on the other side without any gap. Is kept in the state.

これに対して、一対の長さ規定用型枠３０,３２を中子ユニット１６から後退させた姿勢とは、図３に示された一方の長さ規定用型枠３０が矢印Ｒ１方向に転回した姿勢、並びに、図４に示された他方の長さ規定用型枠３２が矢印Ｒ２方向に転回した姿勢を指す。ここで、一対の長さ規定用型枠３０,３２を転回させる方策としては、例えば、各規定用型枠３０,３２の下端側を回転自在に軸支すると共に（図示しない）、当該回転軸を中心に各規定用型枠３０,３２の先端側を転回可能に構成すればよい。 On the other hand, the posture in which the pair of length defining molds 30 and 32 are retracted from the core unit 16 means that one length defining mold 30 shown in FIG. 3 rotates in the direction of the arrow R1. And the posture in which the other length-defining mold 32 shown in FIG. 4 is turned in the direction of arrow R2. Here, as a measure for rotating the pair of length defining molds 30 and 32, for example, the lower end side of each defining mold 30 and 32 is rotatably supported (not shown), and the rotation shaft The tip side of each of the defining molds 30 and 32 may be configured to be able to roll around the center.

この場合、中子ユニット１６と型枠ユニット１８との間から完成品としての側溝再生用構造体２を脱型する際に、上記した回転操作機構４２（操作レバー４２ａ）を操作して係合片４２ｂをフック機構４２から外した後、一対の長さ規定用型枠３０,３２の少なくともいずれか一方を転回させて中子ユニット１６から後退させることで、完成品としての側溝再生用構造体２を、中子ユニット１６及び型枠ユニット１８に干渉させることなく脱型することが可能になる。 In this case, when removing the side groove reproducing structure 2 as a finished product from between the core unit 16 and the formwork unit 18, the above-described rotation operation mechanism 42 (operation lever 42a) is operated to engage. After removing the piece 42 b from the hook mechanism 42, at least one of the pair of length-defining molds 30, 32 is rotated and retracted from the core unit 16, so that a side groove reproducing structure as a finished product is obtained. 2 can be removed without interfering with the core unit 16 and the mold unit 18.

このような製造装置における製造プロセスとしては、まず、例えば一対の幅規定用型枠２０,２２を中子ユニット１６に対して相対的に接近或いは離間させた後、位置決め機構２４,２６によって当該一対の幅規定用型枠２０,２２を中子ユニット１６に対して所定位置に位置決めする。そして、上記した一方側及び他方側保持機構によって一対の長さ規定用型枠３０,３２を、成形材Ｆｓを漏れなく貯留させることができる姿勢（図３〜図６参照）に保持する。これにより、既設側溝の用途に対応させた（具体的には、形状や大きさに一致させた）側溝再生用構造体２を成形することが可能となる。 As a manufacturing process in such a manufacturing apparatus, first, for example, a pair of width defining molds 20 and 22 are relatively approached or separated from the core unit 16, and then the pair of positioning mechanisms 24 and 26 are used to perform the pairing. Are positioned at predetermined positions with respect to the core unit 16. Then, the pair of length-defining molds 30 and 32 are held in a posture (see FIGS. 3 to 6) in which the molding material Fs can be stored without omission by the above-described one-side and other-side holding mechanisms. Thereby, it is possible to form the side groove regenerating structure 2 corresponding to the use of the existing side groove (specifically, matched to the shape and size).

次に、中子ユニット１６と型枠ユニット１８との間に成形材Ｆｓ（図３〜図６参照）を投入して固化させる。これにより、その内面に中子ユニット１６の外面形状が転写されると共に、その表面に型枠ベース２８の外面形状が転写された完成品としての側溝再生用構造体２を製造することができる。 Next, the molding material Fs (see FIGS. 3 to 6) is introduced between the core unit 16 and the mold unit 18 and solidified. Thereby, the outer surface shape of the core unit 16 is transferred to the inner surface, and the side groove regeneration structure 2 as a finished product having the outer surface shape of the mold base 28 transferred to the surface can be manufactured.

続いて、中子ユニット１６と型枠ユニット１８との間から完成品としての側溝再生用構造体２を脱型する。このとき、上記した一方側及び他方側保持機構によって一対の長さ規定用型枠３０,３２の双方或いは一方を、中子ユニット１６から後退させた姿勢に保持する。この場合、例えば、一方側保持機構では、保持シャフト３４を受け部３８から離脱させることで、また、他方側保持機構では、係合片４２ｂをフック機構４４から離脱させることで、当該後退姿勢に保持可能となる。これにより、完成品としての側溝再生用構造体２を、中子ユニット１６及び型枠ユニット１８に干渉させることなく脱型することができる。 Subsequently, the side groove regeneration structure 2 as a finished product is removed from between the core unit 16 and the mold unit 18. At this time, both or one of the pair of length-defining molds 30 and 32 is held in a posture retracted from the core unit 16 by the one-side and other-side holding mechanism described above. In this case, for example, in the one-side holding mechanism, the holding shaft 34 is detached from the receiving portion 38, and in the other-side holding mechanism, the engaging piece 42b is detached from the hook mechanism 44, so that the retracted posture is achieved. It becomes possible to hold. As a result, the side groove recycling structure 2 as a finished product can be removed from the mold without interfering with the core unit 16 and the mold unit 18.

なお、かかる製造装置における製造プロセスにおいて、中子ユニット１６と型枠ユニット１８との間の領域（表面）全体に亘って、予め「離型剤」を塗布しておくことが好ましい。これにより、上記した脱型処理をスムーズ且つ安全確実に行うことができる。なお、離型剤としては、市販のものを利用すればよい。 In the manufacturing process in such a manufacturing apparatus, it is preferable to apply a “release agent” in advance over the entire region (surface) between the core unit 16 and the mold unit 18. Thereby, the above-mentioned demolding process can be performed smoothly and safely. In addition, what is necessary is just to utilize a commercially available thing as a mold release agent.

また、完成品である側溝再生用構造体２に、上記した穿孔１０（図１参照）を一体成形する場合、その孔形状に一致させた外面形状を有する棒状部材４６を用意し、これを中子ユニット１６と型枠ユニット１８との間の領域における適所に着脱自在に位置付ければよい。なお、図面には、棒状部材４６を適所に位置付けるための構成の一例として、棒状部材４６の一端を型枠ベース２８に対して着脱自在に当接させつつ、当該棒状部材４６の他端を支持フレーム４８を介して一対の長さ規定用型枠３０,３２に着脱自在に固定させる機構が示されている。 In addition, when the above-described perforations 10 (see FIG. 1) are integrally formed in the side groove recycling structure 2 that is a finished product, a rod-like member 46 having an outer surface shape that matches the hole shape is prepared. What is necessary is just to detachably position in the suitable place in the area | region between the sub unit 16 and the formwork unit 18. FIG. In the drawing, as an example of a configuration for positioning the rod-shaped member 46 at an appropriate position, one end of the rod-shaped member 46 is detachably brought into contact with the formwork base 28 and the other end of the rod-shaped member 46 is supported. A mechanism for detachably fixing to a pair of length defining molds 30 and 32 via a frame 48 is shown.

かかる機構によれば、例えば、中子ユニット１６と型枠ユニット１８との間に投入された成形材Ｆｓ（図３〜図６参照）が固化した状態において、支持フレーム４８を介して棒状部材４６を引き抜くことで、完成品である側溝再生用構造体２に穿孔１０（図１参照）を一体成形することができる。この場合、上記した脱型処理に際し、かかる穿孔１０に、側溝再生用構造体２を吊り上げるための治具（図示しない）を挿入して牽引することができるようにすれば、当該脱型処理をよりスムーズ且つ安全確実に行うことができる。 According to such a mechanism, for example, in a state where the molding material Fs (see FIGS. 3 to 6) charged between the core unit 16 and the mold unit 18 is solidified, the rod-shaped member 46 is interposed via the support frame 48. As a result, the perforations 10 (see FIG. 1) can be integrally formed in the side groove regeneration structure 2 that is a finished product. In this case, if the jig (not shown) for lifting the side groove regeneration structure 2 can be inserted and pulled in the perforation 10 in the above demolding process, the demolding process is performed. It can be performed more smoothly and safely.

このように、本実施形態によれば、一対の幅規定用型枠２０,２２を中子ユニット１６に対して相対的に接近或いは離間させて所定位置に位置決めすることで、既設側溝の用途に対応させた（具体的には、形状や大きさに一致させた）側溝再生用構造体２を成形することができるため、１台の製造装置だけで、多岐に亘るＵ字型側溝の形態に応じた側溝再生用構造体２を低コストで製造することができる。この場合、保管スペースも製造装置１台分だけで済むため、人件費や管理（保管）費なども低く抑えることができる。 As described above, according to the present embodiment, the pair of width-defining molds 20 and 22 are positioned relatively close to or away from the core unit 16 and positioned at a predetermined position. Since the corresponding structure 2 for regenerating the side groove (specifically, matched to the shape and size) can be formed, it is possible to form a wide variety of U-shaped side grooves with only one manufacturing apparatus. The corresponding side groove regenerating structure 2 can be manufactured at low cost. In this case, since the storage space is only required for one manufacturing apparatus, personnel costs and management (storage) costs can be kept low.

更に、本実施形態では、上記した一方側及び他方側保持機構に、一対の長さ規定用型枠３０,３２を成形材Ｆｓを漏れなく貯留させることができる姿勢（図３〜図６参照）に保持した状態において、当該一対の長さ規定用型枠３０,３２と一対の幅規定用型枠２０,２２との位置関係を一定に保持するための保持構造をさらに付加してもよい。 Further, in the present embodiment, the above-described one-side and other-side holding mechanism can store the pair of length-defining molds 30 and 32 without leakage of the molding material Fs (see FIGS. 3 to 6). In this state, a holding structure for holding the positional relationship between the pair of length defining molds 30, 32 and the pair of width defining molds 20, 22 may be further added.

例えば、一対の長さ規定用型枠３０,３２の両側に嵌合凸片５０を先細り状に対向させて設けると共に、固定型枠２６ａの両側、及び、一方側の幅規定用型枠２０の両側に、先細り形状を成す嵌合凸片５０の外面輪郭に一致した内面形状を有する嵌合凹片５２を設ける。なお、図２及び図４には、一対の長さ規定用型枠３０,３２の片側に嵌合凸片５０を突設し、固定型枠２６ａの両側に嵌合凹片５２を設けた保持構造のみが示されている。 For example, the fitting convex pieces 50 are provided on both sides of the pair of length defining molds 30 and 32 so as to be tapered, and the width defining molds 20 on both sides and one side of the fixed mold 26a. On both sides, a fitting concave piece 52 having an inner surface shape that matches the outer surface contour of the fitting convex piece 50 having a tapered shape is provided. In FIGS. 2 and 4, holding protrusions 50 are provided on one side of the pair of length-defining molds 30 and 32, and fitting recesses 52 are provided on both sides of the fixed mold 26 a. Only the structure is shown.

これによれば、嵌合凸片５０と嵌合凹片５２とが隙間無く密着して嵌合するため、これにより、一対の長さ規定用型枠３０,３２と一対の幅規定用型枠２０,２２との位置関係を一定に保持することができる。即ち、一対の長さ規定用型枠３０,３２と一対の幅規定用型枠２０,２２とが、例えば相対的に傾斜したり、捩れたりする事態の発生を未然に防止することができる。このため、完成品としての精度が一定に維持された側溝再生用構造体２を製造することができる。この結果、大量に側溝再生用構造体２を製造する場合でも、高い歩留りを実現することができる。 According to this, since the fitting convex piece 50 and the fitting concave piece 52 are closely fitted with no gap therebetween, the pair of length defining molds 30 and 32 and the pair of width defining molds are thereby obtained. The positional relationship with 20, 22 can be kept constant. That is, it is possible to prevent the occurrence of a situation in which the pair of length defining molds 30 and 32 and the pair of width defining molds 20 and 22 are relatively inclined or twisted, for example. For this reason, the structure 2 for side groove reproduction | regeneration which the precision as a finished product was maintained constant can be manufactured. As a result, a high yield can be realized even when a large number of side groove reproducing structures 2 are manufactured.

また、本実施形態によれば、上記した一方側保持機構（回転操作部３６、受け部３８）を複数個所に亘って設けることができるため、一方側の幅規定用型枠２０の位置に応じて保持シャフト３４を架け替えることで、当該保持シャフト３４を介して効率よく引っ張り力を作用させることが可能となり、その結果、一対の長さ規定用型枠３０,３２の一方側を、より確実に、一方側の幅規定用型枠２０の両外側に隙間無く隣接（密着）させることができる。なお、本実施形態では一例として、一方側の幅規定用型枠２０を中子ユニット１６に接近させて位置決めした状態（図３参照）と、一方側の型枠を中子ユニット１６から離間させて位置決めした状態（図６(ｂ)参照）が示されている。 In addition, according to the present embodiment, since the one side holding mechanism (the rotation operation unit 36 and the receiving unit 38) described above can be provided at a plurality of locations, it can be provided in accordance with the position of the width defining mold 20 on one side. By replacing the holding shaft 34, it becomes possible to efficiently apply a pulling force via the holding shaft 34. As a result, one side of the pair of length-defining molds 30, 32 can be more reliably attached. In addition, it is possible to adjoin (closely contact) the outer sides of the width defining form 20 on one side without any gap. In this embodiment, as an example, a state in which the width defining mold 20 on one side is positioned close to the core unit 16 (see FIG. 3) and the mold on one side are separated from the core unit 16. The state (see FIG. 6B) is shown.
