Description

本発明は連結具に関し、特に、建築用の型枠を連結して固定する連結具に関する。 The present invention relates to connectors, and in particular to connectors for connecting and fixing construction formwork.

特許文献1に記載されているように、例えば建設工事のコンクリート打設の際用いられる仮設の型枠は、一枚の板材と横に延伸するように該一枚の板材に取り付けて補強する複数本のバタ角とを有する構成になっており、このような型枠を複数枚用意して連結具で連結して固定することにより、一枚の大きな型枠として利用できる発明が提案されている。 As described in Patent Document 1, for example, a temporary formwork used when pouring concrete in a construction project is composed of a single plate material and multiple flap angles that are attached to the plate material and extend horizontally to reinforce it. An invention has been proposed in which multiple such forms are prepared and connected and fixed with connectors, allowing them to be used as one large formwork.

台湾特許第I716319号明細書Taiwan Patent No. I716319

上記型枠において、バタ角の反対側にあるコンクリート打設面は、通常は面一にすることが理想的である。 In the above formwork, it is usually ideal to make the concrete pouring surface on the opposite side of the butt corner flush.

しかし、特許文献1に記載される技術では複数枚の型枠を連結具で連結して固定する技術が開示されているものの、複数枚の型枠それぞれが有するコンクリート打設面を面一にする技術に関しては記載されていない。特に、特許文献1に記載される技術では1つの連結具の両端部にそれぞれ1つの型枠を取り付けることで2枚の型枠を連結する構成になっており、該2枚の型枠がそれぞれ連結具を受け入れる孔と連結具とのサイズに誤差がある際、連結具の型枠に対する回転軸はぶれるようになり、該2枚の型枠がそれぞれ有するコンクリート打設面は不一致になる。 However, although the technology described in Patent Document 1 discloses a technique for connecting and fixing multiple formwork pieces with connectors, it does not disclose a technique for making the concrete pouring surfaces of the multiple formwork pieces flush. In particular, the technology described in Patent Document 1 is configured to connect two formwork pieces by attaching one formwork piece to each end of one connector, and if there is an error in the size of the connector and the holes that receive the connectors in the two formwork pieces, the axis of rotation of the connector with respect to the formwork piece will become misaligned, and the concrete pouring surfaces of the two formwork pieces will not match.

上記問題点に鑑みて、ぶれずに型枠に装着できる連結具の提供を目的とする。 In consideration of the above problems, the aim is to provide a connector that can be attached to a formwork without wobbling.

上記目的に達成すべく、本発明は、第1の連結対象と第2の連結対象を連結するための連結具であって、
所定の軸線に沿って延伸し、且つ、外表面にネジ山が形成されている螺合部と、
前記螺合部に隣接し、且つ、外周面は所定の第1のテーパ比を有する小径部分及び前記螺合部から離れた側にあって、外周面は所定の第2のテーパ比を有する大径部分を有するように、前記螺合部の一端から前記軸線に沿って漸次広がる錐台形状に形成された位置決め部と、
前記位置決め部の前記大径部分に連接しているヘッド部と、を備え、
前記ヘッド部は、前記位置決め部の前記大径部分に連接し、且つ、前記軸線に直交する断面積が前記大径部分の最も広い箇所の断面積よりも大きく形成されて前記螺合部側に面する係止面を有する係止部分と、前記係止部分から前記軸線に沿って前記螺合部の反対側へ延伸する接続部分と、を有し、
前記第1の連結対象を挿通して該第1の連結対象から露出する前記螺合部で前記第2の連結対象と螺合しながら該第1の連結対象を前記第2の連結対象側に押し付けることにより、前記第1の連結対象と前記第2の連結対象とを連結する、ことを特徴とする連結具を提供する。
In order to achieve the above object, the present invention provides a connector for connecting a first connection object and a second connection object, comprising:
a screw portion extending along a predetermined axis and having a screw thread formed on an outer surface thereof;
a positioning portion formed in a frustum shape that gradually widens from one end of the screw thread portion along the axis so that the positioning portion is adjacent to the screw thread portion and has an outer circumferential surface having a small diameter portion with a predetermined first taper ratio and an outer circumferential surface having a large diameter portion with a predetermined second taper ratio on a side away from the screw thread portion;
a head portion connected to the large diameter portion of the positioning portion,
the head portion includes a locking portion connected to the large diameter portion of the positioning portion and having a locking surface facing the screw-engagement portion, the locking portion having a cross-sectional area perpendicular to the axis larger than the cross-sectional area of the large diameter portion at its widest point, and a connecting portion extending from the locking portion along the axis to the opposite side of the screw-engagement portion,
The present invention provides a connector that connects the first connection object and the second connection object by inserting the first connection object through the first connection object and pressing the first connection object against the second connection object while screwing the screw-connecting portion exposed from the first connection object into the second connection object.

上記構成により、本発明の連結具は、位置決め部が軸線に沿って漸次広がる錐台形状に形成されているので、この錐台形状が形成されることにより、該連結具はぶれずに型枠に装着されることができ、これにより各型枠がそれぞれ有するコンクリート打設面を面一にすることが簡単になる。 With the above configuration, the connector of the present invention has a positioning portion formed into a frustum shape that gradually widens along the axis. This frustum shape allows the connector to be attached to the formwork without wobbling, making it easy to make the concrete pouring surfaces of each formwork flush.

FIG.

以下は各図面を参照して本発明の連結具の各実施形態について詳しく説明する。 The following describes in detail each embodiment of the connector of the present invention with reference to the drawings.

図1~図3に本発明の連結具の第1の実施形態が示されており、図示のように、本発明の連結具1の第1の実施形態は、図2において左右に延伸する所定の軸線Lに沿って延伸する円柱体である螺合部11と、螺合部11の一端(図2における左端)から軸線Lに沿って延伸する位置決め部12と、螺合部11と位置決め部12との間に介在し、且つ、直径が螺合部11のネジ山111(後述)を含めた直径より短い小径軸部15と、位置決め部12に連接しているヘッド部13と、操作部14と、を備えている。 1 to 3 show a first embodiment of the connector of the present invention. As shown in the figures, the first embodiment of the connector 1 of the present invention comprises a screw-type portion 11 which is a cylinder extending along a predetermined axis L extending left and right in FIG. 2, a positioning portion 12 which extends along the axis L from one end (the left end in FIG. 2) of the screw-type portion 11, a small diameter shaft portion 15 which is interposed between the screw-type portion 11 and the positioning portion 12 and has a diameter shorter than the diameter including the threads 111 (described later) of the screw-type portion 11, a head portion 13 which is connected to the positioning portion 12, and an operating portion 14.

なお、以下では螺合部11がある図2における右側を前方側と称し、操作部14がある図2における左側を後方側と称する。 In the following, the right side in FIG. 2 where the screw-in portion 11 is located will be referred to as the front side, and the left side in FIG. 2 where the operating portion 14 is located will be referred to as the rear side.

螺合部11の外表面にネジ山111が形成されている。 A screw thread 111 is formed on the outer surface of the screw-fitting portion 11.

位置決め部12は、螺合部11に隣接し、且つ、外周面において所定の第1のテーパ比を有する小径部分121と、螺合部11から離れた側にあって、外周面において所定の第2のテーパ比を有する大径部分122と、を有するように、螺合部11の一端から軸線Lに沿って後方に向かって漸次広がる錐台形状に形成されている。 The positioning portion 12 is formed in a frustum shape that gradually widens from one end of the threaded portion 11 toward the rear along the axis L, so that it has a small diameter portion 121 adjacent to the threaded portion 11 and having a predetermined first taper ratio on its outer circumferential surface, and a large diameter portion 122 located away from the threaded portion 11 and having a predetermined second taper ratio on its outer circumferential surface.

この実施形態において、小径部分121と大径部分122とは、一体的に形成されており、前記第1のテーパ比及び前記第2のテーパ比は、いずれも1:8である。 In this embodiment, the small diameter portion 121 and the large diameter portion 122 are integrally formed, and the first taper ratio and the second taper ratio are both 1:8.

ヘッド部13は、円柱体に形成され、位置決め部12の大径部分122にし、且つ、軸線Lに直交する断面積が大径部分122の最も広い箇所の断面積よりも大きく形成されて螺合部11側に面する係止面を有する係止部分131と、係止部分131から軸線Lに沿って螺合部11の反対側へ延伸する接続部分132と、位置決め部12の大径部分122と係止部分132との間に介在し、且つ、直径が位置決め部12の大径部分122の直径が最も長い箇所より短い小径連結部分16と、を有する。また、この実施形態において、ヘッド部13の接続部分132には、螺合部11の反対側、すなわち後方に向かって開口して操作部14を受け入れられる収容凹部1321と、軸線Lと略直交する方向に沿って該接続部分132を貫通し且つ収容凹部1321に連通する固定孔1323と、該固定孔1323内に挿入される固定ボルト1322(図2参照)と、を有する。なお、ヘッド部13は円柱体以外の形状に形成されることも可能である。 The head portion 13 is formed into a cylindrical body and has a locking portion 131 that faces the large diameter portion 122 of the positioning portion 12 and has a locking surface facing the screw-engaging portion 11 side, the cross-sectional area perpendicular to the axis L being larger than the cross-sectional area of the large diameter portion 122 at its widest point, a connecting portion 132 that extends from the locking portion 131 along the axis L to the opposite side of the screw-engaging portion 11, and a small diameter connecting portion 16 that is interposed between the large diameter portion 122 of the positioning portion 12 and the locking portion 132 and has a diameter shorter than the longest point of the large diameter portion 122 of the positioning portion 12 . In this embodiment, the connection portion 132 of the head portion 13 has an accommodating recess 1321 that opens toward the opposite side of the screwing portion 11, i.e., toward the rear, and receives the operating portion 14, a fixing hole 1323 that passes through the connection portion 132 in a direction substantially perpendicular to the axis L and communicates with the accommodating recess 1321, and a fixing bolt 1322 (see FIG. 2) that is inserted into the fixing hole 1323. The head portion 13 can also be formed into a shape other than a cylindrical body.

操作部14は、形状がヘッド部13の収容凹部1321に対応する柱状であり、一部が接続部分132における収容凹部1321内に嵌入され、収容凹部1321内において固定ボルト1322により挿通されることにより、ヘッド部13に対して相対回転が不可能に固定されている。また、操作部14の接続部分132から露出する部分は、多角柱状(図3参照、この実施形態では6角柱)となっている。この構成により、多角柱状となっている操作部14の接続部分132から露出する部分と嵌め合う手工具などを用いて、本発明の連結具全体を軸線Lを中心として回転させる操作が可能となる。 The operating part 14 is columnar in shape corresponding to the accommodation recess 1321 of the head part 13, and a part of it is fitted into the accommodation recess 1321 in the connection part 132, and a fixing bolt 1322 is inserted into the accommodation recess 1321, thereby fixing it to the head part 13 so that it cannot rotate relative to the head part 13. In addition, the part of the operating part 14 exposed from the connection part 132 is polygonal columnar (see FIG. 3, in this embodiment, a hexagonal column). With this configuration, it is possible to rotate the entire connector of the present invention around the axis L using a hand tool that fits into the polygonal column-shaped part of the operating part 14 exposed from the connection part 132.

図示のように、この実施形態において固定孔1323はヘッド部13の接続部分132を貫通しているが、固定孔1323は操作部14を構成するためのものなので、収容凹部1321に連通していれば、固定孔1323及び該固定孔1323内に挿入される固定ボルト1322は接続部分132を貫通する必要はない。 As shown in the figure, in this embodiment, the fixing hole 1323 penetrates the connection part 132 of the head part 13, but since the fixing hole 1323 is for forming the operating part 14, as long as it is connected to the storage recess 1321, the fixing hole 1323 and the fixing bolt 1322 inserted into the fixing hole 1323 do not need to penetrate the connection part 132.

また、固定ボルト1322も操作部14を貫通する必要はない。固定ボルト1322が軸線Lと略直交する方向に沿って操作部14内に挿し込む構成であれば、操作部14をヘッド部13に対して相対回転が不可能に係合することができる。 Furthermore, the fixing bolt 1322 does not need to penetrate the operating unit 14. If the fixing bolt 1322 is configured to be inserted into the operating unit 14 along a direction substantially perpendicular to the axis L, the operating unit 14 can be engaged with the head unit 13 so that it cannot rotate relative to the head unit 13.

また、図示されていないが、操作部14自体を省略することも可能である。すなわち、操作部14が省略される場合では、ヘッド部13の接続部分132に形成されて後方に向かって開口する凹部が円形ではない多角形の断面を有することで、多角柱状の手工具を受け入れて該手工具による回転操作を受けることによって、本発明の連結具全体を軸線Lを中心として回転させる操作が可能となる。 Although not shown, it is also possible to omit the operating unit 14 itself. In other words, when the operating unit 14 is omitted, the recess formed in the connection portion 132 of the head portion 13 and opening toward the rear has a polygonal cross section rather than a circular one, and by receiving a polygonal column-shaped hand tool and receiving a rotation operation by the hand tool, it is possible to rotate the entire connector of the present invention around the axis L.

更に、図4は本発明の連結具の第2の実施形態の構成が示される側面図であるが、図示のように、本発明の連結具1の第2の実施形態ではヘッド部13の接続部分132から後方へ延伸するようにヘッド部13と一体的に形成された操作部14を備えている。すなわち、操作部14をヘッド部13と一体的に形成する構成により、操作部14をヘッド部13に係合するための収容凹部1321や固定ボルト1322、固定孔1323(図2参照)を省略できる。 Furthermore, FIG. 4 is a side view showing the configuration of a second embodiment of the connector of the present invention. As shown in the figure, the second embodiment of the connector 1 of the present invention includes an operating part 14 that is integrally formed with the head part 13 so as to extend rearward from the connection part 132 of the head part 13. In other words, by forming the operating part 14 integrally with the head part 13, it is possible to omit the receiving recess 1321, fixing bolt 1322, and fixing hole 1323 (see FIG. 2) for engaging the operating part 14 with the head part 13.

図5及び図6には本発明の連結具1を2つ用いて、第1の連結対象及び第2の連結対象としての2枚の型枠2を連結する様子が示されており、各型枠2はいずれも挿通孔221と螺合穴222とが形成されている。以下では説明の都合で図中の左側にある型枠2を第1の型枠2Aと呼称し、右側にある型枠2第2の型枠2Bと呼称するが、第1の型枠2Aと第2の型枠2Bはいずれもほぼ同じ構成を有する。 Figures 5 and 6 show how two connectors 1 of the present invention are used to connect two formwork sheets 2 as the first and second connection objects, with each formwork sheet 2 having an insertion hole 221 and a screw hole 222. For ease of explanation, the formwork sheet 2 on the left side of the figure will be referred to as the first formwork sheet 2A, and the formwork sheet 2 on the right side will be referred to as the second formwork sheet 2B below, but both the first formwork sheet 2A and the second formwork sheet 2B have substantially the same configuration.

また、該第1の型枠2Aと第2の型枠2Bを連結する2つの連結具1に関しても、図中の上方側に示されている連結具1を第1の連結具1Aと呼称し、図中の下方側に示されている連結具1を第2の連結具1Bと呼称する。 Furthermore, with regard to the two connectors 1 that connect the first formwork 2A and the second formwork 2B, the connector 1 shown on the upper side of the figure is referred to as the first connector 1A, and the connector 1 shown on the lower side of the figure is referred to as the second connector 1B.

なお、第1の型枠2Aと第2の型枠2Bのいずれにも板体21が装着されており、これらの板体21は第1の型枠2Aもしくは第2の型枠2Bが装着される型枠装着面211と、該型枠装着面211の反対側にあるコンクリート打設面212と、を有する構成になっている。 Both the first formwork 2A and the second formwork 2B are fitted with plates 21, and these plates 21 have a formwork mounting surface 211 to which the first formwork 2A or the second formwork 2B is attached, and a concrete pouring surface 212 on the opposite side of the formwork mounting surface 211.

すなわち、第1の連結具1Aは、第1の螺合部11Aと、第1の位置決め部12Aと、第1のヘッド部13Aと、第1の操作部14Aと、を備えている。第1の位置決め部12Aは、第1の小径部分121A及び第1の幅広部分122Aを有する錐台形状に形成されている。第1のヘッド部13Aは第1の係止部分131Aを有する。 That is, the first connector 1A includes a first screw-in portion 11A, a first positioning portion 12A, a first head portion 13A, and a first operating portion 14A. The first positioning portion 12A is formed in a frustum shape having a first small diameter portion 121A and a first wide portion 122A. The first head portion 13A has a first locking portion 131A.

第2の連結具1Bは、第2の螺合部11Bと、第2の位置決め部12Bと、第2のヘッド部13Bと、第2の操作部14Bと、を備えている。第2の位置決め部12Bは、第2の小径部分121B及び第2の幅広部分122Bを有する錐台形状に形成されている。第2のヘッド部13Bは第2の係止部分131Bを有する。 The second connector 1B includes a second screw-in portion 11B, a second positioning portion 12B, a second head portion 13B, and a second operating portion 14B. The second positioning portion 12B is formed in a frustum shape having a second small diameter portion 121B and a second wide portion 122B. The second head portion 13B includes a second locking portion 131B.

また、第1の型枠2Aは第1の型枠部22Aを有し、該第1の型枠部22Aには、第1の挿通孔221A及び第1の螺合穴222Aが形成されている。第1の挿通孔221Aには、第1のヘッド収容部223A及び第1の幅広テーパ状孔部224Aが形成されており、第1の螺合穴222Aには、第1のネジ穴部225A及び第1の小径テーパ状孔部226Aが形成されている。 The first mold 2A has a first mold section 22A, and a first insertion hole 221A and a first screw hole 222A are formed in the first mold section 22A. A first head accommodating section 223A and a first wide tapered hole section 224A are formed in the first insertion hole 221A, and a first screw hole section 225A and a first small diameter tapered hole section 226A are formed in the first screw hole 222A.

ここで、第1の幅広テーパ状孔部224Aの形状は、第1の連結具1Aにおける第1の位置決め部12Aが有する第1の幅広部分122Aを受け入れて当接できるように対応して形成されており、そして第1のネジ穴部225Aは第2の連結具1Bの第2の螺合部11Bのネジ山111と螺合可能に形成され、更に、第1の小径テーパ状孔部226Aは第2の連結具1Bにおける第2の位置決め部12Bが有する第2の幅広部分122Bを受け入れて当接できるように対応して形成されている。 Here, the shape of the first wide tapered hole 224A is formed so as to receive and abut the first wide portion 122A of the first positioning portion 12A of the first connector 1A, and the first screw hole 225A is formed so as to be able to screw into the thread 111 of the second screw-in portion 11B of the second connector 1B, and further, the first small diameter tapered hole 226A is formed so as to receive and abut the second wide portion 122B of the second positioning portion 12B of the second connector 1B.

第2の型枠2Bは第2の型枠部22Bを有し、該第2の型枠部22Bには、第2の挿通孔221B及び第2の螺合穴222Bが形成されている。第2の挿通孔221Bには、第2のヘッド収容部223B及び第2の幅広テーパ状孔部224Bが形成されており、第2の螺合穴222Bには、第2のネジ穴部225B及び第2の小径テーパ状孔部226Bが形成されている。 The second mold 2B has a second mold portion 22B, in which a second insertion hole 221B and a second screw hole 222B are formed. A second head accommodating portion 223B and a second wide tapered hole portion 224B are formed in the second insertion hole 221B, and a second screw hole portion 225B and a second small diameter tapered hole portion 226B are formed in the second screw hole 222B.

ここで、第2の幅広テーパ状孔部224Bの形状は、第2の連結具1Bにおける第2の位置決め部12Bが有する第2の幅広部分122Bを受け入れて当接できるように対応して形成されており、そして第2のネジ穴部225Bは第1の連結具1Aの第1の螺合部11Aと螺合可能に形成され、更に、第2の小径テーパ状孔部226Bは第1の連結具1Aにおける第1の位置決め部12Aが有する第1の幅広部分122Aを受け入れて当接できるように対応して形成されている。 Here, the shape of the second wide tapered hole 224B is formed so as to receive and abut the second wide portion 122B of the second positioning portion 12B of the second connector 1B, and the second screw hole 225B is formed so as to be able to screw into the first screw-engagement portion 11A of the first connector 1A, and further, the second small diameter tapered hole 226B is formed so as to receive and abut the first wide portion 122A of the first positioning portion 12A of the first connector 1A.

図示のように、第1の連結具1Aは、第1の螺合部11A側から第1の型枠2Aの第1の挿通孔221Aを挿通し、第1の螺合部11Aと第1の操作部14Aとは、第1の挿通孔221Aの両端の開口外にそれぞれ露出している。また、第1の連結具1Aの第1の位置決め部12Aに関しては、第1の小径部分121Aは第1の螺合部11Aと共に第1の挿通孔221Aの外側に露出し、第1の幅広部分122Aは第1の挿通孔221A内において第1の幅広テーパ状孔部224Aに当接する。また、第1のヘッド部13Aの第1の係止部分131Aは、第1の挿通孔221Aの第1のヘッド収容部223A内に収容されている。 As shown in the figure, the first connector 1A is inserted through the first through-hole 221A of the first formwork 2A from the first screwing portion 11A side, and the first screwing portion 11A and the first operating portion 14A are exposed outside the openings at both ends of the first through-hole 221A. In addition, with regard to the first positioning portion 12A of the first connector 1A, the first small diameter portion 121A is exposed outside the first through-hole 221A together with the first screwing portion 11A, and the first wide portion 122A abuts against the first wide tapered hole portion 224A in the first through-hole 221A. In addition, the first locking portion 131A of the first head portion 13A is accommodated in the first head accommodating portion 223A of the first through-hole 221A.

第1の連結具1Aの第1の挿通孔221Aから露出する第1の螺合部11A及び第1の小径部分121Aは、第2の型枠2Bの第2の型枠部22Bに形成される第2の螺合穴222B内に挿し込まれ、第1の螺合部11Aは第2のネジ穴部225Bと螺合し、第1の小径部分121Aは第2の小径テーパ状孔部226Bに当接する。 The first screw portion 11A and the first small diameter portion 121A exposed from the first insertion hole 221A of the first connector 1A are inserted into the second screw hole 222B formed in the second formwork portion 22B of the second formwork 2B, the first screw portion 11A screws into the second screw hole portion 225B, and the first small diameter portion 121A abuts against the second small diameter tapered hole portion 226B.

これにより、第1の連結具1Aの第1の螺合部11Aと第2の型枠2Bの第2の型枠部22Bに形成される第2の螺合穴222B内の第2のネジ穴部225Bとの螺合が進行し、第1の螺合部11Aが第2のネジ穴部225B内に深く進入する程、第1の連結具1Aの第1の位置決め部12Aの第1の幅広部分122Aが第1の型枠2Aの第1の挿通孔221Aに当接し、そして第1のヘッド部13Aは第1の係止部分131Aも第1のヘッド収容部223Aと第1の幅広テーパ状孔部224Aとの間にある当接面に当接するので、第1の型枠2Aを第2の型枠2B側へきつく押し付けて固定することができる。 As a result, the first screw portion 11A of the first connector 1A is screwed into the second screw hole 222B formed in the second formwork portion 22B of the second formwork 2B, and the deeper the first screw portion 11A penetrates into the second screw hole 225B, the more the first wide portion 122A of the first positioning portion 12A of the first connector 1A abuts against the first insertion hole 221A of the first formwork 2A, and the first locking portion 131A of the first head portion 13A also abuts against the abutment surface between the first head accommodating portion 223A and the first wide tapered hole portion 224A, so that the first formwork 2A can be firmly pressed against the second formwork 2B and fixed.

一方、第2の連結具1Bは、第2の螺合部11B側から第2の型枠2Bの第2の挿通孔221Bを挿通し、第2の螺合部11Bと第2の操作部14Bとは、第2の挿通孔221Bの両端の開口外にそれぞれ露出している。また、第2の連結具1Bの第2の位置決め部12Bに関しては、第2の小径部分121Bは第2の螺合部11Bと共に第2の挿通孔221Bの外側に露出し、第2の幅広部分122Bは第2の挿通孔221B内において第2の幅広テーパ状孔部224Bに当接する。また、第2のヘッド部13Bの第2の係止部分131Bは、第2の挿通孔221Bの第2のヘッド収容部223B内に収容されている。 On the other hand, the second connector 1B is inserted through the second through-hole 221B of the second formwork 2B from the second screwing portion 11B side, and the second screwing portion 11B and the second operating portion 14B are exposed to the outside of the openings at both ends of the second through-hole 221B. In addition, with regard to the second positioning portion 12B of the second connector 1B, the second small diameter portion 121B is exposed to the outside of the second through-hole 221B together with the second screwing portion 11B, and the second wide portion 122B abuts against the second wide tapered hole portion 224B in the second through-hole 221B. In addition, the second locking portion 131B of the second head portion 13B is accommodated in the second head accommodating portion 223B of the second through-hole 221B.

第2の連結具1Bの第2の挿通孔221Bから露出する第2の螺合部11B及び第2の小径部分121Bは、第1の型枠2Aの第1の型枠部22Aに形成される第1の螺合穴222A内に挿し込み、第2の螺合部11Bは第1のネジ穴部225Aと螺合し、第2の小径部分121Bは第1の小径テーパ状孔部226Aに当接する。 The second screw-threaded portion 11B and the second small diameter portion 121B exposed from the second insertion hole 221B of the second connector 1B are inserted into the first screw-threaded hole 222A formed in the first formwork portion 22A of the first formwork 2A, the second screw-threaded portion 11B screws into the first screw hole portion 225A, and the second small diameter portion 121B abuts against the first small diameter tapered hole portion 226A.

これにより、第2の連結具1Bの第2の螺合部11Bが第1の型枠2Aの第1の型枠部22Aに形成される第1の螺合穴222A内の第1のネジ穴部225Aとの螺合が進行し、第2の螺合部11Bが第1のネジ穴部225A内に深く進入する程、第2の連結具1Bの第2の位置決め部12Bの第2の幅広部分122Bが第2の型枠2Bの第2の挿通孔221Bに当接し、そして第2のヘッド部13Bは第2の係止部分131Bも第2のヘッド収容部223Bと第2の幅広テーパ状孔部224Bとの間にある当接面に当接するので、第2の型枠2Bを第1の型枠2A側へきつく押し付けて固定することができる。 As a result, the second screwing portion 11B of the second connector 1B is screwed into the first screw hole portion 225A in the first screw hole 222A formed in the first form portion 22A of the first form 2A, and the deeper the second screwing portion 11B penetrates into the first screw hole portion 225A, the more the second wide portion 122B of the second positioning portion 12B of the second connector 1B abuts against the second insertion hole 221B of the second form 2B, and the second locking portion 131B of the second head portion 13B also abuts against the abutment surface between the second head receiving portion 223B and the second wide tapered hole portion 224B, so that the second form 2B can be firmly pressed against the first form 2A and fixed.

以上、本発明の好ましい実施形態を説明したが、本発明はこれらに限定されるものではなく、最も広い解釈の精神及び範囲内に含まれる様々な構成として、全ての修飾及び均等な構成を包含するものとする。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these, and encompasses all modifications and equivalent configurations as various configurations that fall within the spirit and scope of the broadest interpretation.

このように、本発明の連結具1は、位置決め部12が小径部分121及び幅広部分122を有するように、軸線Lに沿って後方に向けて漸次広がる錐台形状に形成されているので、該連結具1を利用して対応する型枠2側の挿通孔221を挿通する際、挿通孔221に位置決め部12の幅広部分122と係合するための係合構造が形成されていなくても、位置決め部12が錐台形状に形成されているため型枠2側の挿通孔221の開口近くに当接して該連結具1の更なる挿通は阻止されるようになるので、該連結具1はぶれずに型枠に装着されることができる。 In this way, the connector 1 of the present invention is formed in a frustum shape that gradually widens toward the rear along the axis L so that the positioning portion 12 has a small diameter portion 121 and a wide portion 122. Therefore, when the connector 1 is used to insert the corresponding insertion hole 221 on the formwork 2 side, even if the insertion hole 221 does not have an engagement structure for engaging with the wide portion 122 of the positioning portion 12, the positioning portion 12 is formed in a frustum shape and abuts near the opening of the insertion hole 221 on the formwork 2 side, preventing further insertion of the connector 1, so the connector 1 can be attached to the formwork without wobbling.

更に、該連結具1の螺合部11が他の1つの型枠2の螺合穴222内のネジ穴部に深くねじ込まれる程、2つの型枠2を確実に連結することが可能となり、そして各型枠2に形成される挿通孔221及び螺合穴222の位置や寸法が正しければ、連結具1を用いて複数の型枠2を連結する際、各型枠2に取り付けられるコンクリート打設用の板体21のコンクリート側に面する各コンクリート打設面212を確実に面一にすることができる。 Furthermore, the deeper the screw-threaded portion 11 of the connector 1 is screwed into the threaded hole portion of the screw-threaded hole 222 of the other formwork 2, the more reliably the two formworks 2 can be connected. If the positions and dimensions of the insertion holes 221 and screw-threaded holes 222 formed in each formwork 2 are correct, when multiple formworks 2 are connected using the connector 1, the concrete pouring surfaces 212 facing the concrete side of the concrete pouring plate 21 attached to each formwork 2 can be reliably made flush.
