Description

本発明は、鉄筋コンクリート造の柱と、Ｈ形鋼からなる鉄骨梁と、の柱梁接合部の型枠構造、および、柱梁接合部の構築方法に関する。   The present invention relates to a formwork structure of a column beam joint portion between a reinforced concrete column and a steel beam made of H-shaped steel, and a method for constructing the column beam joint portion.

従来より、鉄筋コンクリート造の建物の柱や梁を構築する際に、コンクリート型枠として型枠パネルを組み合わせたものを用いることが提案されている。（特許文献１、２参照）。
このような型枠パネルを用いることにより、型枠の転用回数を多くして、型枠の材料費や加工費などの施工コストを低減するとともに、工期を短縮できる。 Conventionally, it has been proposed to use a combination of formwork panels as concrete formwork when building columns and beams of reinforced concrete buildings. (See Patent Documents 1 and 2).
By using such a formwork panel, it is possible to increase the number of times the formwork is transferred, reduce construction costs such as material cost and processing cost of the formwork, and shorten the construction period.

ところで、鉄筋コンクリート柱の柱頭部に鉄骨梁を接合する混合架構がある。この混合架構の柱梁接合部を構築する場合には、鉄骨梁を配置した後、コンクリート型枠を建て込んで、コンクリートを打設することになる。
しかしながら、この柱梁接合部に上述のような型枠パネルを建て込む際、鉄骨梁が型枠パネルを貫通するため、型枠パネルに梁型の開口を設ける必要がある。したがって、型枠パネルの加工手間がかかってしまい、工期が長期化し、施工コストが増大するおそれがあった。 By the way, there is a mixed frame that joins a steel beam to the column head of a reinforced concrete column. When constructing the beam-column joint of this mixed frame, after placing the steel beam, a concrete formwork is built and concrete is placed.
However, when the above-described formwork panel is built in the column beam joint, the steel beam penetrates the formwork panel, and thus it is necessary to provide a beam-type opening in the formwork panel. Therefore, the processing of the formwork panel is time-consuming, the construction period is prolonged, and the construction cost may increase.

本発明は、工期を短縮して施工コストを低減できる柱梁接合部の型枠構造および柱梁接合部の構築方法を提供することを目的とする。   An object of the present invention is to provide a formwork structure of a beam-column joint and a method of constructing the beam-column joint that can shorten the work period and reduce the construction cost.

請求項１に記載の柱梁接合部の型枠構造は、鉄筋コンクリート造の柱（例えば、後述の柱２０）と、Ｈ型形状の鉄骨梁（例えば、後述の鉄骨梁３０）と、の柱梁接合部（例えば、後述の柱梁接合部１０）の型枠構造であって、前記鉄骨梁の下フランジ（例えば、後述の下フランジ３１Ａ）と上フランジ（例えば、後述の上フランジ３１Ｂ）との間の凹部（例えば、後述の凹部３６）は、前記柱梁接合部のコンクリート打設面となる位置で、塞ぎ板（例えば、後述の塞ぎ板３３）で塞がれており、前記柱梁接合部のコンクリート打設面となる側面のうち、前記鉄骨梁および前記塞ぎ板を除いた部分は、複数の型枠パネル（例えば、後述の梁下型枠パネル４０および梁側型枠パネル５０）で覆われており、前記塞ぎ板の端縁には、板状の連結片（例えば、後述の縦リブ３５）が立設され、前記型枠パネルの端縁には、板状の連結片（例えば、後述の縦リブ５２）が立設され、前記型枠パネルは、当該型枠パネルの連結片と前記塞ぎ板の連結片とを治具（例えば、後述のネットクランプ７０）で挟持して、前記塞ぎ板に仮固定されることを特徴とする。   The formwork structure of the beam-column joint according to claim 1 is a column beam composed of a reinforced concrete column (for example, a column 20 described later) and an H-shaped steel beam (for example, a steel beam 30 described later). A formwork structure of a joint (for example, a beam-to-column joint 10 described later), and a lower flange (for example, a lower flange 31A described later) and an upper flange (for example, an upper flange 31B described later) of the steel beam. A concave portion (for example, a concave portion 36 described later) between them is a position that becomes a concrete placing surface of the beam-column joint portion and is closed by a block plate (for example, a block plate 33 described later). Of the side surface that is the concrete placement surface of the portion, the portion excluding the steel beam and the closing plate is a plurality of formwork panels (for example, a below-mentioned formwork panel 40 and a beam side formwork panel 50 described later). It is covered, and a plate-shaped connecting piece ( For example, vertical ribs 35 to be described later are erected, and plate-shaped connecting pieces (for example, vertical ribs 52 to be described later) are erected on the edge of the formwork panel. The connecting piece of the frame panel and the connecting piece of the closing plate are clamped by a jig (for example, a net clamp 70 described later) and temporarily fixed to the closing plate.

この発明によれば、鉄骨梁のフランジ間の凹部を塞ぎ板で塞いだので、コンクリート型枠に設ける梁型の開口を矩形状とすることができる。
さらに、複数の型枠パネルを組み合わせてコンクリート型枠を構成したので、型枠パネルを矩形状などの単純な形状にできるから、工期を短縮して施工コストを低減できる。 According to the present invention, since the concave portion between the flanges of the steel beam is closed with the closing plate, the beam-type opening provided in the concrete mold can be made rectangular.
Furthermore, since the concrete formwork is configured by combining a plurality of formwork panels, the formwork panel can be made into a simple shape such as a rectangular shape, so that the construction period can be shortened and the construction cost can be reduced.

また、型枠パネルおよび塞ぎ板に連結片を設けておき、これら連結片をクランプで挟持することで、型枠パネルと塞ぎ板とを連結する。よって、仮設のクランプを用いて、型枠パネルと塞ぎ板とを簡単に連結したり、連結を簡単に解除したりできるので、低コストで施工効率を向上できる。   Moreover, a connection piece is provided in the formwork panel and the closing plate, and the formwork panel and the closing plate are connected by clamping the connection pieces with a clamp. Therefore, since the formwork panel and the closing plate can be easily connected or disconnected using a temporary clamp, construction efficiency can be improved at low cost.

また、型枠パネル同士の固定は、対向する型枠パネル同士をセパレータなどの連結材を用いて仮固定するのではなく、隣り合う型枠パネルの縦リブ同士をクランプで挟持することで仮固定する。よって、型枠パネルを建て込んでも、柱梁接合部内に設ける鉄筋や鋼材等の配置に影響を及ぼさない。   In addition, fixing between formwork panels is not temporarily fixed between connecting formwork panels using a connecting material such as a separator, but is temporarily fixed by clamping vertical ribs of adjacent formwork panels with clamps. To do. Therefore, even if the formwork panel is installed, it does not affect the arrangement of reinforcing bars and steel materials provided in the column beam joint.

ここで、前記塞ぎ板は、前記鉄骨梁に溶接で固定されていることが好ましい。   Here, it is preferable that the closing plate is fixed to the steel beam by welding.

この発明によれば、溶接により塞ぎ板を鉄骨梁に強固に固定したので、塞ぎ板の内側にコンクリートを打設しても、塞ぎ板はこのコンクリートの側圧に十分に耐えることができる。
また、塞ぎ板を鉄骨梁に溶接しておくことで、塞ぎ板と型枠パネルの連結片同士を精度よく所定の位置に仮固定し、コンクリート型枠を組み立てることができる。 According to the present invention, since the closing plate is firmly fixed to the steel beam by welding, the closing plate can sufficiently withstand the side pressure of the concrete even if concrete is placed inside the closing plate.
Further, by welding the closing plate to the steel beam, the connecting pieces of the closing plate and the formwork panel can be temporarily fixed at predetermined positions with high accuracy, and the concrete formwork can be assembled.

請求項２に記載の柱梁接合部の構築方法は、鉄筋コンクリート造の柱と、Ｈ形鋼からなる鉄骨梁と、の立体状の柱梁接合部の構築方法であって、端縁に板状の連結片が立設された塞ぎ板と、端縁に板状の連結片が立設された型枠パネルと、を用意し、前記鉄骨梁の下フランジと上フランジとの間の凹部を、前記柱梁接合部のコンクリート打設面となる位置で、塞ぎ板で塞ぐとともに、前記柱梁接合部のコンクリート打設面となる側面のうち、前記鉄骨梁および前記塞ぎ板を除いた部分を、複数の型枠パネルで覆って、当該型枠パネルの連結片と前記塞ぎ板の連結片とを治具で挟持して、前記型枠パネルを前記塞ぎ板に仮固定することを特徴とする。   The method for constructing a beam-column joint according to claim 2 is a method for constructing a three-dimensional beam-column joint of a reinforced concrete column and a steel beam made of H-shaped steel, and has a plate-like shape at an edge. Preparing a block plate in which the connecting piece is erected and a formwork panel in which a plate-like connecting piece is erected on the edge, and a recess between the lower flange and the upper flange of the steel beam, At the position to be the concrete placement surface of the beam-column joint portion, the portion is closed with a closing plate, and the portion of the side surface to be the concrete placement surface of the beam-column joint portion excluding the steel beam and the closing plate, It is covered with a plurality of formwork panels, and the connecting piece of the formwork panel and the connecting piece of the closing plate are clamped by a jig, and the formwork panel is temporarily fixed to the closing plate.

この発明によれば、上述の請求項１と同様の効果がある。   According to the present invention, there is an effect similar to that of the first aspect.

本発明によれば、鉄骨梁のフランジ間の凹部を塞ぎ板で塞いだので、コンクリート型枠に設ける梁型の開口を矩形状とすることができる。さらに、複数の型枠パネルを組み合わせてコンクリート型枠を構成したので、型枠パネルを矩形状などの単純な形状にできるから、工期を短縮して施工コストを低減できる。   According to the present invention, since the concave portion between the flanges of the steel beam is closed with the closing plate, the beam-type opening provided in the concrete mold can be made rectangular. Furthermore, since the concrete formwork is configured by combining a plurality of formwork panels, the formwork panel can be made into a simple shape such as a rectangular shape, so that the construction period can be shortened and the construction cost can be reduced.

図１は、本発明の一実施形態に係る柱梁接合部の型枠構造が適用された柱梁接合部１０の斜視図である。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a beam-column joint 10 to which a formwork structure of a beam-column joint according to an embodiment of the present invention is applied.

この柱梁接合部１０は、建物１の構造体の一部であり、立体形状ここでは直方体形状の鉄筋コンクリート造の躯体である。
すなわち、建物１は、鉄筋コンクリート造の柱および鉄骨梁を備える混合架構を有しており、柱梁接合部１０は、この建物１の鉄筋コンクリート造の柱２０の柱頭部であり、鉄筋コンクリート造の柱２０と４本のＨ型形状のＨ形鋼からなる鉄骨梁３０とが接合された部分である。 The column beam joint 10 is a part of the structure of the building 1 and is a reinforced concrete frame having a three-dimensional shape, that is, a rectangular parallelepiped shape.
That is, the building 1 has a mixed frame including a reinforced concrete column and a steel beam, and the column beam joint 10 is a column head of the reinforced concrete column 20 of the building 1 and the reinforced concrete column 20. And four steel beams 30 made of H-shaped steel with an H-shape.

この柱梁接合部１０を構築する手順について、図２のフローチャートを参照しながら説明する。
まず、ステップＳ１では、図３に示すように、柱頭部を残して柱２０を構築する。
すなわち、柱２０について鉄骨梁３０の梁下の高さまでコンクリートを打設して、この柱２０の柱頭部以外の部分を、柱躯体２０Ａとして構築する。
ここで、柱躯体２０Ａの四隅には、それぞれ、上方に延びる柱主筋２１が３本ずつ配置される。 The procedure for constructing the column beam joint 10 will be described with reference to the flowchart of FIG.
First, in step S1, as shown in FIG. 3, the column 20 is constructed leaving the column head.
That is, concrete is cast to the height of the column 20 below the beam of the steel beam 30, and a portion other than the column head of the column 20 is constructed as the column housing 20A.
Here, three column main bars 21 extending upward are arranged at each of the four corners of the column housing 20A.

ステップＳ２では、図３に示すように、柱躯体２０Ａの上に梁接合部材２３を載置して取り付ける。   In step S2, as shown in FIG. 3, the beam joining member 23 is mounted on the columnar housing 20A.

梁接合部材２３は、４本の鉄骨梁３０の端部を平面視で略十字形状に接合したものである。
各鉄骨梁３０は、Ｈ形鋼であり、下フランジ３１Ａおよび上フランジ３１Ｂと、これら上下のフランジ３１Ａ、３１Ｂ同士を連結するウエブ３２と、を備える。
ここで、下フランジ３１Ａと上フランジ３１Ｂとの間の凹部３６は、柱梁接合部１０の側面のコンクリート打設面となる位置で、塞ぎ板３３で塞がれている。
この塞ぎ板３３は、凹部３６を構成する下フランジ３１Ａ、ウエブ３２、および上フランジ３１Ｂに溶接で固定されている。 The beam joining member 23 is obtained by joining the ends of four steel beams 30 in a substantially cross shape in plan view.
Each steel beam 30 is H-shaped steel, and includes a lower flange 31A and an upper flange 31B, and a web 32 that connects the upper and lower flanges 31A and 31B.
Here, the recess 36 between the lower flange 31 </ b> A and the upper flange 31 </ b> B is closed by the closing plate 33 at a position that becomes a concrete placing surface on the side surface of the column beam joint 10.
The closing plate 33 is fixed to the lower flange 31A, the web 32, and the upper flange 31B constituting the recess 36 by welding.

塞ぎ板３３は、鋼板に山形鋼を溶接固定して製作されたものであり、板状の塞ぎ板本体３４と、この塞ぎ板本体３４の外端縁に立設された連結片としての縦リブ３５と、を備える。
この塞ぎ板３３を設けることにより、鉄骨梁３０の断面形状は、柱梁接合部１０のコンクリート表面となる位置では矩形状となっている。 The closing plate 33 is manufactured by welding and fixing an angle steel to a steel plate, and a plate-like closing plate body 34 and vertical ribs as connecting pieces erected on the outer edge of the closing plate body 34. 35.
By providing the closing plate 33, the cross-sectional shape of the steel beam 30 is rectangular at a position that becomes the concrete surface of the column beam joint 10.

ステップＳ３では、図３に示すように、柱頭部に帯筋２２を配筋する。
すなわち、帯筋２２は、柱主筋２１を囲んで配筋され、鉛直方向に所定間隔おきに配置されている。したがって、一部の帯筋２２は、ウエブ３２を貫通して配筋されている。 In step S3, as shown in FIG.
That is, the strips 22 are arranged around the column main bars 21 and are arranged at predetermined intervals in the vertical direction. Therefore, a part of the reinforcing bars 22 are arranged through the web 32.

ステップＳ４では、図４に示すように、柱躯体２０Ａの上にコンクリート型枠２４を建て込む。
図５は、コンクリート型枠２４を建て込んだ状態を示す正面図である。図６は、図５のＡ−Ａ断面図である。 In step S4, as shown in FIG. 4, the concrete mold 24 is built on the columnar frame 20A.
FIG. 5 is a front view showing a state in which the concrete mold 24 is built. 6 is a cross-sectional view taken along the line AA in FIG.

コンクリート型枠２４は、柱梁接合部１０のコンクリート打設面となる側面のうち、鉄骨梁３０および塞ぎ板３３を除いた部分を覆うものである。
このコンクリート型枠２４は、鉄骨梁３０の直下となる部分を覆う矩形状の梁下型枠パネル４０と、柱梁接合部１０鉄骨梁３０同士の間の部分を覆う矩形状の梁側型枠パネル５０と、で構成される。 The concrete formwork 24 covers a portion of the side surface that becomes the concrete placement surface of the column beam joint 10 except for the steel beam 30 and the closing plate 33.
The concrete formwork 24 includes a rectangular beam formwork panel 40 that covers a portion directly below the steel beam 30 and a rectangular beam side formwork that covers a portion between the column beam joints 10 and the steel beams 30. And a panel 50.

梁下型枠パネル４０は、鋼板に山形鋼を溶接固定して製作されたものであり、板状のパネル本体４１と、このパネル本体４１の両側の端縁に設けられて略鉛直に延びる連結片としての縦リブ４２と、パネル本体４１の上下の端縁に設けられて略水平に延びる横リブ４３と、を備える。   The under-beam formwork panel 40 is manufactured by welding and fixing angle steel to a steel plate, and is connected to a plate-like panel main body 41 and edge portions on both sides of the panel main body 41 and extending substantially vertically. A vertical rib 42 as a piece and a horizontal rib 43 provided on the upper and lower end edges of the panel body 41 and extending substantially horizontally are provided.

梁側型枠パネル５０は、鋼板に山形鋼を溶接固定して製作されたものであり、板状のパネル本体５１と、このパネル本体５１の両側の端縁に設けられて略鉛直に延びる連結片としての縦リブ５２と、パネル本体５１の上下の端縁および中央部に設けられて略水平に延びる横リブ５３と、を備える。   The beam-side formwork panel 50 is manufactured by welding and fixing an angle steel to a steel plate, and is provided with a plate-like panel body 51 and a connection extending substantially vertically provided on both side edges of the panel body 51. A vertical rib 52 as a piece and a horizontal rib 53 provided at the upper and lower end edges and the center of the panel main body 51 and extending substantially horizontally are provided.

互いに隣接する梁側型枠パネル５０は、縦リブ５２同士をボルト５４で固定することでユニット化されて、梁側型枠ユニット６０となっている。この梁側型枠ユニット６０は、平面視で略Ｌ字形状であり、柱梁接合部１０の出隅部を覆うことになる。   The beam-side formwork panels 50 adjacent to each other are unitized by fixing the vertical ribs 52 with bolts 54 to form a beam-side formwork unit 60. The beam-side formwork unit 60 is substantially L-shaped in a plan view, and covers the protruding corner of the column beam joint 10.

梁下型枠パネル４０と梁側型枠パネル５０とは、梁下型枠パネル４０の縦リブ４２と梁側型枠パネル５０の縦リブ５２とを治具としてのネットクランプ７０で挟持することで、仮固定される。
また、梁側型枠パネル５０と塞ぎ板３３とは、梁側型枠パネル５０の縦リブ５２と塞ぎ板３３の縦リブ３５とをネットクランプ７０で挟持することで、仮固定される。 The under-beam formwork panel 40 and the beam-side formwork panel 50 sandwich the vertical rib 42 of the under-beam formwork panel 40 and the vertical rib 52 of the beam-side formwork panel 50 with a net clamp 70 as a jig. And temporarily fixed.
The beam-side formwork panel 50 and the closing plate 33 are temporarily fixed by sandwiching the vertical ribs 52 of the beam-side formwork panel 50 and the vertical ribs 35 of the closing plate 33 with the net clamp 70.

ステップＳ５では、コンクリート型枠２４の内側にコンクリートを打設する。   In step S <b> 5, concrete is placed inside the concrete formwork 24.

本実施形態によれば、以下のような効果がある。
（１）鉄骨梁３０のフランジ３１Ａ、３１Ｂ間の凹部３６を塞ぎ板３３で塞いだので、コンクリート型枠２４に設ける梁型の開口を矩形状とすることができる。加えて、コンクリート型枠２４を複数の型枠パネル４０、５０を組み合わせて構成したので、型枠パネル４０、５０を矩形状にできるから、工期を短縮して施工コストを低減できる。 According to this embodiment, there are the following effects.
(1) Since the concave portion 36 between the flanges 31A and 31B of the steel beam 30 is closed by the closing plate 33, the beam-type opening provided in the concrete mold 24 can be rectangular. In addition, since the concrete formwork 24 is configured by combining a plurality of formwork panels 40 and 50, the formwork panels 40 and 50 can be formed in a rectangular shape, so that the construction period can be shortened and the construction cost can be reduced.

（２）梁側型枠パネル５０および塞ぎ板３３に縦リブ５２、３５を設けておき、これら縦リブ５２、３５をネットクランプ７０で挟持することで、梁側型枠パネル５０と塞ぎ板３３とを連結する。よって、仮設のネットクランプ７０を用いて、梁側型枠パネル５０と塞ぎ板３３とを簡単に連結したり、連結を簡単に解除したりできる。
また、梁下型枠パネル４０に縦リブ４２を設けておき、これら縦リブ５２、４２をネットクランプ７０で挟持することで、梁側型枠パネル５０と梁下型枠パネル４０とを連結する。よって、梁側型枠パネル５０と梁下型枠パネル４０とを簡単に連結したり、連結を簡単に解除したりできる。
したがって、低コストで施工効率を向上できる。 (2) The vertical ribs 52 and 35 are provided on the beam-side formwork panel 50 and the closing plate 33, and the vertical ribs 52 and 35 are sandwiched by the net clamp 70, whereby the beam-side formwork panel 50 and the closing plate 33 are provided. And Therefore, the beam-side form panel 50 and the closing plate 33 can be easily connected to each other using the temporary net clamp 70, or the connection can be easily released.
Further, the vertical ribs 42 are provided in the under-beam form panel 40, and the vertical ribs 52, 42 are sandwiched by the net clamp 70, thereby connecting the beam-side form panel 50 and the under-beam form panel 40. . Therefore, the beam-side formwork panel 50 and the under-beam formwork panel 40 can be easily connected or disconnected.
Therefore, construction efficiency can be improved at low cost.

また、型枠パネル４０、５０同士は、対向する型枠パネル同士をセパレータなどの連結材を用いて仮固定するのではなく、隣り合う型枠パネル４０、５０の縦リブ４２、５２同士をネットクランプ７０で挟持することで仮固定する。よって、型枠パネル４０、５０を建て込んでも、柱梁接合部１０内に設けた鉄筋や鋼材等の配置に影響を及ぼさない。   Moreover, the formwork panels 40 and 50 do not temporarily fix the formwork panels facing each other using a connecting material such as a separator, but connect the vertical ribs 42 and 52 of the adjacent formwork panels 40 and 50 to the net. It is temporarily fixed by being clamped by the clamp 70. Therefore, even if the formwork panels 40 and 50 are installed, the arrangement of reinforcing bars and steel materials provided in the column beam joint 10 is not affected.

（３）溶接により塞ぎ板３３を鉄骨梁３０に強固に固定したので、塞ぎ板３３の内側にコンクリートを打設しても、塞ぎ板３３はこのコンクリートの側圧に十分に耐えることができる。
また、塞ぎ板３３を鉄骨梁３０に溶接しておくことで、塞ぎ板３３と型枠パネル４０、５０の連結片３５、４２、５２同士を精度よく所定の位置に仮固定し、コンクリート型枠２４を組み立てることができる。 (3) Since the closing plate 33 is firmly fixed to the steel beam 30 by welding, even if concrete is placed inside the closing plate 33, the closing plate 33 can sufficiently withstand the side pressure of the concrete.
Further, by welding the closing plate 33 to the steel beam 30, the connecting pieces 35, 42, 52 of the closing plate 33 and the formwork panels 40, 50 are temporarily fixed at predetermined positions with high accuracy, and the concrete formwork 24 can be assembled.

（４）施工コストを低減するために、型枠パネルをできる限り多く転用することが要請されているが、木質型枠パネルでは、転用を重ねる度に型枠の損傷が大きくなり、それほど転用できない、という問題があった。
しかし、本発明では、型枠パネル４０、５０を鋼製としたので、型枠セット時の精度を確保できるうえに、転用回数を増やすことができる。 (4) In order to reduce the construction cost, it is required to divert as much of the formwork panel as possible. However, with the wooden formwork panel, the formwork damage increases each time the diversion is repeated, and it cannot be diverted so much. There was a problem.
However, in the present invention, since the formwork panels 40 and 50 are made of steel, the accuracy at the time of formwork setting can be secured and the number of diversions can be increased.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
本実施形態では、型枠パネル４０、５０を建て込む前に、塞ぎ板３３を鉄骨梁３０に溶接固定しておいたが、これに限らず、塞ぎ板３３を型枠パネル４０、５０に仮固定した後、この塞ぎ板３３を鉄骨梁３０に溶接固定してもよい。 It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
In this embodiment, the closing plate 33 is welded and fixed to the steel beam 30 before the formwork panels 40 and 50 are installed. However, the present invention is not limited to this, and the closing plate 33 is temporarily attached to the formwork panels 40 and 50. After the fixing, the closing plate 33 may be fixed to the steel beam 30 by welding.

また、本実施形態では、型枠パネル４０、５０同士あるいは型枠パネル５０と塞ぎ板３３とを連結する治具として、ネットクランプ７０を用いたが、これに限らず、一組のボルトおよびナットを用いてもよい。   In the present embodiment, the net clamp 70 is used as a jig for connecting the mold panels 40 and 50 or between the mold panel 50 and the closing plate 33. However, the present invention is not limited to this, and a set of bolts and nuts is used. May be used.
