本考案は、複数段に重ねられた多角形状の発泡
プラスチツク製型枠を法面に整列して支持固定す

割を果たすものである。 The cast-in-place frame construction method takes more time to construct than the block method that uses precast members, but it is used when a stable slope can be obtained, a steep slope is accompanied by spring water, a long slope, or the soil quality is not good. It serves to stabilize the slope and prevent the collapse of the slope surface layer when rock formations such as joints and cracks are developed, or when floating stones cannot be stopped by concrete spraying.

けでも重労働となり、ひいては作業性もかなり劣
るものであつた。 By the way, this cast-in-place frame construction method is generally carried out by installing formwork on the slope and pouring mortar (including concrete), and the material of the formwork greatly affects workability and cost. It had been. In other words, some formwork has traditionally been made of steel plates so that they can be reused.
Not only is this expensive, but it is also very heavy, so even carrying it up is labor intensive, especially when constructing on steep slopes, and the workability is also quite poor.

全く作業を行なうことが不可能であつた。 In addition, cardboard molds have been developed as lightweight and easy-to-work formwork, but because they are made of cardboard, they absorb water when mortar hardens, significantly inhibiting the strength of the mortar after hardening. However, this is especially a problem in the summer. Furthermore, because the insulation properties are poor, the moisture in the poured mortar may freeze in the winter, and the required strength is often not achieved and it is often unable to function as a framework, especially in the winter. It was impossible to carry out any work in extremely cold regions such as the San'in region, Hokuriku region, or Hokkaido.
本考案者は上記諸点に鑑み断熱性・保水性を有

の大きさに構成でき、かつ、法面の起伏に容易に
沿わせることが可能な型枠及びこの型枠を用いた
法枠の構築方法についても発明を既に特許出願
(特願昭58−120637)している。 In view of the above points, the inventor of the present invention utilized foamed plastic with heat insulating and water-retaining properties as formwork for the slope, and by further dividing it, it could be constructed into various sizes, and the undulations of the slope could be adjusted. The company has already filed a patent application (Japanese Patent Application No. 120,637/1982) for a formwork that can be easily made to fit the shape of a frame and a method for constructing a legal frame using this formwork.
しかし、既特許出願に係る型枠では、構築すべ
き法枠の高さが制限されることになる。すなわち
押出成型機の性能により型枠自体の高さが決定さ
れるので、法面の傾斜や起伏に応じて高い法枠を
構築することができない。このため、法枠を高く
構築するべく型枠構成片を複数段に積み重ねて構
成した型枠を利用しなければならない必要があつ
た。 However, with the formwork related to existing patent applications, the height of the frame to be constructed is limited. That is, since the height of the form itself is determined by the performance of the extrusion molding machine, it is not possible to construct a high slope depending on the slope and undulations of the slope. For this reason, in order to build the legal frame high, it was necessary to use a formwork constructed by stacking formwork constituent pieces in multiple stages.
そこで本考案者は鋭意研究の結果、従来の型枠
連結具を改良することにより、複数段に積み重ね
られた型枠構成片相互の連結と共に型枠相互間の
連結支持を可能とした型枠連結具を開発した。 Therefore, as a result of intensive research, the inventor of the present invention improved the conventional formwork connectors, thereby making it possible to connect the formwork components stacked in multiple tiers together, as well as connect and support the formworks. Developed the tool.
本考案に係る型枠連結具は、型枠止ピンと共に
用いるものであつて、型枠止ピンと型枠連結具に
設けた支持部とによつて型枠に支持固定するもの
で、型枠相互間にこの型枠連結具を介在すること
によつて型枠を法面上に整列して敷設できるよう
構成したものである。 The formwork connector according to the present invention is used together with a formwork retaining pin, and is supported and fixed to the formwork by the formwork retainer pin and the support part provided on the formwork connector, and the formwork is mutually connected. By interposing this formwork connector in between, the formworks can be laid in alignment on the slope.
もつとも本考案に係る型枠連結具は、型枠を分
割した型枠構成片だけでなく一体として型枠の連
結にも利用できるもので、発泡プラスチツク製で
かつ、複数段に積み重ねられた型枠であれば、そ
の大きさや形状を限定するものではない。 Of course, the formwork connector according to the present invention can be used not only to connect the formwork component pieces obtained by dividing the formwork, but also to connect the formwork as a whole. If so, there are no limitations on its size or shape.
以下、本考案を図面に示す実施例に基づいて詳
細に説明する。 Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
第1図aは本考案に係る型枠連結具1の一実施
例を示す斜視図である。 FIG. 1a is a perspective view showing an embodiment of the formwork connector 1 according to the present invention.
この型枠連結具1は両端部に夫々四個づつ差込
部2を有し、差込部2は先端部には挿通部3を設
けている。そして本体4両端に支持部5を設け、
この支持部5により型枠6相互間の間隔を決定し
ている。つまり第1図bに示すように複数段に積
み重ねることにより構成した発泡プラスチツク製
型枠6の各側面に設けた差込孔7にこの差込部2
を支持部5が型枠6に接するまで挿通して差込部
2の先端部に設けた挿通部3に型枠止ピン8を挿
通して型枠6に型枠連結具1を支持固定するよう
にしたものである。この場合、枠端太12を設け
て型枠止めピン8による固定を安定よくすると共
に型枠6自体の補強材としている。 This formwork connector 1 has four insertion portions 2 at each end, and each insertion portion 2 has an insertion portion 3 at its tip. Support portions 5 are provided at both ends of the main body 4,
The support portion 5 determines the distance between the formworks 6. In other words, as shown in FIG. 1b, the insertion portion 2 is inserted into the insertion hole 7 provided on each side of the foamed plastic formwork 6, which is constructed by stacking the foamed plastic in multiple stages.
is inserted until the support part 5 contacts the formwork 6, and the formwork retaining pin 8 is inserted into the insertion part 3 provided at the tip of the insertion part 2 to support and fix the formwork connector 1 to the formwork 6. This is how it was done. In this case, the frame edge 12 is provided to ensure stable fixing by the formwork fixing pins 8 and to serve as a reinforcing material for the formwork 6 itself.
第2図に示すように法面9の型枠6敷設面はほ
とんどが凹部或いは凸部となつているので、法面
8に敷設するべき型枠6を全て直線状に並べられ
るものではなく。前述した形状の型枠連結具1だ
けであれば型枠6の連結箇所に無理が生じるのは
やむをえず、型枠6を大きく変形させてしまつた
り或いは破損してしまう等型枠6の寿命を著しく
短くしてしまうことになる。 As shown in FIG. 2, most of the formwork 6 laying surface of the slope 9 has concave or convex portions, so the formwork 6 to be laid on the slope 8 cannot all be lined up in a straight line. If only the formwork connector 1 having the above-mentioned shape is used, it is unavoidable that the formwork 6 will be strained at the connection points, and the formwork 6 may be greatly deformed or damaged, etc., which may shorten the lifespan of the formwork 6. This will shorten it significantly.
このため、第3図a,bに示すように本体4両
端にある少なくとも一方の支持部5を本体4の上
下方向に非垂直に設ければ、法面9の起伏に応じ
て無理なく型枠6を連結することが可能となる。
尚、本図に示す台形状のものの他平行四辺形状の
ものも本考案に含むことは言うまでもない。 For this reason, if at least one of the supporting parts 5 at both ends of the main body 4 is provided non-perpendicularly in the vertical direction of the main body 4 as shown in FIG. 6 can be connected.
In addition to the trapezoidal shape shown in this figure, it goes without saying that the present invention also includes a parallelogram shape.
また、10は鉄筋支持部であつて棒材11を本
体4に取り付けその部分に鉄筋を支持固定するも
のである。棒材11は型枠連結具1の強度を大き
くする上でも効果的であるが、第4図aに示すよ
うに棒材11をX字状に取り付ければより強度を
大きくすることができる。もつとも、第4図bに
示すように本体4に凹部を設けてこれを鉄筋支持
部10としても実施可能である。 Further, reference numeral 10 denotes a reinforcing bar support part, which attaches a bar 11 to the main body 4 and supports and fixes the reinforcing bar to that part. The bars 11 are effective in increasing the strength of the formwork connector 1, but the strength can be further increased by attaching the bars 11 in an X-shape as shown in FIG. 4a. However, as shown in FIG. 4b, it is also possible to provide a recess in the main body 4 and use this as the reinforcing bar support part 10.
本実施例に示すものはほんの一例であつて、
種々の形状を有する法面9にあつては台形状或い
は平行四辺形状の型枠連結具1を上下左右逆にし
て用いることによつてあらゆる法面9にも対応す
ることができる。 What is shown in this example is just an example,
For slopes 9 having various shapes, it is possible to accommodate any slope 9 by using trapezoidal or parallelogram-shaped formwork connectors 1 inverted vertically and horizontally.
ここで、差込部2は第5図に示すように型枠連
結具1の両端部に夫々各段の型枠5に対応してた
だ一つだけ設けるようにしてもよい。勿論、差込
部2を各段の型枠5に二個以上挿通するようにし
てもよく、型枠連結具1の両端に夫々異なつた数
だけ設けるようにしてもよい。 Here, as shown in FIG. 5, only one insertion part 2 may be provided at both ends of the formwork connector 1, corresponding to each stage of the formwork 5. Of course, two or more insertion portions 2 may be inserted through the formwork 5 of each stage, or different numbers may be provided at both ends of the formwork connector 1.
以上のように本考案に係る型枠連結具は、型枠
連結具に設けた支持部と型枠止ピンにより複数段
に積み重ねられた型枠を確実に支持固定できるよ
うにしたもので、各段の型枠を強固に連結して高
さの高い法枠を構築すると共に極めて容易に法面
の起伏に沿わせて法枠を敷設することができ、か
つ、型枠自体に無理が生じることなく再利用でき
る頻度が高くなりコストダウンに大きく貢献する
というすこぶる有益な効果を有するものである。 As described above, the formwork connector according to the present invention is capable of reliably supporting and fixing formwork stacked in multiple stages using the support part provided on the formwork connector and the formwork retaining pin. It is possible to firmly connect the formwork of the tiers to construct a high-height slope frame, and it is possible to extremely easily lay the slope frame along the undulations of the slope, and the formwork itself is not strained. This has the extremely beneficial effect of increasing the frequency of reuse, which greatly contributes to cost reduction.
