【産業上の利用分野】[Industrial applications]

本願発明は、2個の型枠基体を接合させて、コンクリート注入空間を形成する コンクリート型枠締結装置の自動係脱機構に関する。 The present invention relates to an automatic engaging / disengaging mechanism of a concrete form fastening device that joins two form bases to form a concrete pouring space.

【0002】[0002]

【従来の技術】[Prior art]

従来からコンクリート型枠における2つの型枠体の締結に、トグル機構を用い ることは広く知られていた。かかるトグル機構の構成は、トグルレバーの回動軸 を一方の型枠体に軸支し、連結部材の先端部に係合具が取付けられた連結部材を トグルレバーの先端部に軸支し、該係合具と係合する受具は他方の型枠体に取付 けられて成るものである。かかる受具に係合具を係合させた後、トグルレバーを 回動させて、係合固定及び係合解放(以下、『係脱』と言う。)を行うものであ る。 It has been widely known that a toggle mechanism is used for fastening two formwork bodies in a concrete formwork. In the structure of such a toggle mechanism, the rotating shaft of the toggle lever is pivotally supported on one of the mold bodies, and the connecting member having the engaging member attached to the tip end portion of the connecting member is pivotally supported at the tip end portion of the toggle lever. The receiving tool that engages with the engaging tool is attached to the other mold body. After engaging the engagement tool with the receiving tool, the toggle lever is rotated to perform engagement fixation and engagement release (hereinafter referred to as "engagement / disengagement").

【0003】 しかし、特に大型の型枠では、接合辺に沿って多数の締結手段であるトグル機 構を所定の間隔で配置する必要があり、これらのを一々係合着脱させて2つの型 枠体の型組み、又は型開きを行うのは、非常に煩雑であり作業性の悪いものであ った。 これを解決するものとして、トグル機構の一連の操作のみで自動的に(又はこ れに連動して)受具と係合具との係脱を行う機構が、先に当該出願人以外の者か ら実用新案公告平成3−27765号、実用新案公開平成3−106006号と して提案されている。この機構の詳細は、上記公報に譲るが、その構成の特徴は 、トグル機構が軸支された一方の型枠に、連結ロッドの先端部に取付けられた係 合を案内するガイド部材を別体で取付け、その係合具をガイド部材に形成された 傾斜面、又は慴動溝に沿って移動させることにより、自動的に係合具と係合させ るものである。However, particularly in a large-sized mold, it is necessary to arrange a plurality of toggle mechanisms, which are fastening means, at predetermined intervals along the joint side, and these are engaged and removed one by one to form two molds. It was very troublesome to perform body assembly or mold opening, and workability was poor. As a solution to this, a mechanism that automatically (or in conjunction with this) engages and disengages the receiving device and the engaging device with only a series of operations of the toggle mechanism is a person other than the applicant. Therefore, it is proposed as Public Utility Model Publication No. Heisei 3-27765 and Utility Model Publication Heisei 3-106006. The details of this mechanism are given in the above-mentioned publication, but the feature of the structure is that a guide member attached to the tip of the connecting rod is separately provided on one of the molds on which the toggle mechanism is pivotally supported. And the engaging member is automatically engaged with the engaging member by moving the engaging member along the inclined surface formed on the guide member or the sliding groove.

【0004】[0004]

【考案が解決しようとする課題】 ところで、上記機構は、トグル機構の操作のみで係脱することができる点で、 それ以前のトグル機構を用いた上記の周知型枠締結装置よりも利点があるが、ガ イド部材が1つの連結ロッドに対してその両側に2個づつ配置される構成のため 、部品点数が多くなってしまう欠点があった。また、連結ロッドの移動は、それ ぞれのガイド部材の形状に影響されるため、その形状にバラツキがあるときは、 スムーズな移動が得られないこともあった。By the way, the above mechanism is advantageous in that it can be disengaged only by operating the toggle mechanism, compared with the above-mentioned known mold fastening device using the toggle mechanism before that. However, since there are two guide members on each side of one connecting rod, the number of parts is large. Further, since the movement of the connecting rod is affected by the shape of each guide member, smooth movement may not be obtained when the shape has variations.

【0005】 そこで本願考案は、上記課題の解決を目的とするもので、1つのガイド部材の 構成のみで複数個の締結機構の係脱を自動的に、かつ同時に行うことができるコ ンクリート型枠締結装置の自動係脱機構を提供するものである。Therefore, the present invention is intended to solve the above-mentioned problems, and a concrete formwork capable of automatically engaging and disengaging a plurality of fastening mechanisms with only one guide member configuration. An automatic engagement / disengagement mechanism of a fastening device is provided.

【0006】[0006]

【実施例】 次に本願考案にかかる自動係脱機構の具体的実施の一例を、図面に基づき以下 にその詳細を説明する。 図1は実施例の自動係脱機構を示した斜視図あり、図2はこれを上方から見た 平面図である。[Embodiment] Next, an example of a concrete implementation of the automatic engagement / disengagement mechanism according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an automatic engagement / disengagement mechanism of the embodiment, and FIG. 2 is a plan view of the automatic engagement / disengagement mechanism seen from above.

【0008】 型枠体A、Bは、互いに接合してコンクリート注入空間(図示省略。)を区画 し、その区画空間が所望のコンクリート製品の形状を形作るように、外形状が成 形されている。 型枠体A、Bの接合部1に沿って、略丸棒状の作動ロッド2が配置されており 、該作動ロッド2は、回動自在に環装された支持部材3によって一方の型枠体A に軸回転可能にして取付けられている。該作動ロッド2には、トグルレバー4を 構成する長楕円板状の2枚のレバープレート5、5が固定されている。The formwork bodies A and B are joined to each other to define a concrete pouring space (not shown), and an outer shape is formed so that the defined space forms a desired concrete product shape. . A substantially round rod-shaped operating rod 2 is arranged along the joint portion 1 of the mold bodies A and B, and the operating rod 2 is supported by a supporting member 3 which is rotatably attached to one of the mold bodies. It is attached to A so that the shaft can rotate. Two elliptic plate-shaped lever plates 5 and 5 which form a toggle lever 4 are fixed to the operating rod 2.

【0009】 該レバープレート5の先端部5aには、作動ロッド2を迂回するように半円状 に湾曲した板状の連結部材6が取付けられている。この取付けは、該2枚のレバ ープレート5、5で、連結部材6の先端部6aを挟持し、かつピン7によって回 動自在に行われている。 該連結部材6の他端部6bには、他方の型枠体Bの方向に延びた、係合具8が 連結固定されている。該係合具8は、先端が略T字状にされた係止部8aと、そ の幹部にネジ溝が刻設された螺合部8bとから構成されている。この螺合部8b が他端部6bに螺合固定される。これにより、このネジ込み量を適宜調節するこ とにより係合具8の長さが調節されることになる。そして長さ設定後は、回止め ナット9によって固定される。A plate-shaped connecting member 6 that is curved in a semicircle shape is attached to the tip portion 5 a of the lever plate 5 so as to bypass the operating rod 2. This attachment is carried out by sandwiching the tip end portion 6a of the connecting member 6 between the two lever plates 5 and 5 and rotatably by a pin 7. An engaging member 8 extending in the direction of the other mold B is fixedly connected to the other end 6b of the connecting member 6. The engagement tool 8 is composed of a locking portion 8a having a substantially T-shaped tip, and a threaded portion 8b having a thread groove formed in its trunk portion. This screwed portion 8b is screwed and fixed to the other end portion 6b. As a result, the length of the engaging member 8 can be adjusted by adjusting the screwing amount as appropriate. After setting the length, it is fixed by the rotation stop nut 9.

【0010】 前記係合具8と係合する受具10は、係止部8aの両端部に適合し、型枠体A 方向への移動を抑止するように略L字フック状を成し、型枠体Bの接合部1付近 の対応する位置に2個1組で配置固定されている。 なお、図面においては、トグルレバー4、連結部材6、係合具8、及び受具1 0からなるトグル機構を用いた締結機構は、1組のみが示されているが、実際は かかる締結機構が、接合部1の何箇所かに適宜の間隔をもって、複数個配置され るものである。The receiving member 10 that engages with the engaging member 8 has a substantially L-shaped hook shape so as to be fitted to both ends of the locking portion 8a and to prevent movement in the direction of the mold A. Two pieces are arranged and fixed in a pair at corresponding positions near the joint portion 1 of the mold body B. It should be noted that, in the drawings, only one set of the fastening mechanism using the toggle mechanism including the toggle lever 4, the connecting member 6, the engaging tool 8, and the receiving tool 10 is shown, but in reality, such a fastening mechanism is used. A plurality of joints 1 are arranged at appropriate intervals.

【0011】 次に、型枠体Aの接合部1に接する位置には、型枠体B方向に延びる板状のガ イド部材11が取付けられており、その面は、型枠体Aの側面と垂直になるよう に配置されている。該ガイド部材11の面には、型枠体B方向にかつ外側に略円 弧状に湾曲して延びるガイド長孔12が貫通して形成されている。 また該ガイド長孔12を貫通し、前記作動ロッド2と平行になるようして、連 結ナッド13が配置されており、該連結ロッド13は、前記複数個の連結部材6 の他端部6bどうしを、架け渡すようにして取付け固定されている。Next, a plate-shaped guide member 11 extending in the direction of the mold body B is attached at a position in contact with the joint portion 1 of the mold body A, and the surface thereof is the side surface of the mold body A. It is arranged so that it is perpendicular to. A guide slot 12 is formed penetrating the surface of the guide member 11 so as to extend in the direction of the mold body B and to extend outward in a substantially arcuate shape. Further, a connecting nud 13 is arranged so as to penetrate through the elongated guide hole 12 and be parallel to the operating rod 2, and the connecting rod 13 has the other end 6b of the plurality of connecting members 6. They are attached and fixed so as to bridge each other.

【0012】 14は、作動ロッド2の適宜の位置に固定された筒状の嵌合受具であり、作動 ロッド2を回動させる操作杆15の先端部が着脱自在にして嵌合取付けられるも のである。Reference numeral 14 is a cylindrical fitting receiver fixed to an appropriate position of the actuation rod 2, and the tip end of an operating rod 15 for rotating the actuation rod 2 is detachably fitted and attached. Of.

【作用】[Action]

上記構成により、本願考案は次のように作用する。 2つの型枠体A、Bの締結は、次の順序で行われる。先ず、2つの型枠体A、 Bを互いに、又は一方を移動させて接合させる。このとき、連結ロッド13は、 ガイド長孔12の先端部12aに位置し、係合具8は受具10から外側に離れた 状態にある(図2において2点破線図)。ここで、嵌合受具14に嵌合取付けら れた操作杆15を回動させると、作動ロッド2に固定されたトグルレバー4は回 動する(矢印a)。これに連動して連結部材6とその先端部6aに取付けられた 係合具8が、ガイド長孔12の形状に習って、ガイド部材11の幹部12b方向 に慴動移動する(矢印b)。これにより、係合受具8の係止部8aは、受具10 と係合し、トグル機構の作用により固定されることになる。 With the above configuration, the present invention operates as follows. The two formwork bodies A and B are fastened in the following order. First, the two mold bodies A and B are joined to each other or one of them is moved. At this time, the connecting rod 13 is positioned at the tip portion 12a of the elongated guide hole 12, and the engagement tool 8 is separated from the receiving tool 10 to the outside (two-dot broken line diagram in FIG. 2). Here, when the operating rod 15 fitted and attached to the fitting receiver 14 is rotated, the toggle lever 4 fixed to the operating rod 2 is rotated (arrow a). In conjunction with this, the connecting member 6 and the engaging member 8 attached to the tip portion 6a of the connecting member 6 follow the shape of the guide elongated hole 12 and slidably move toward the trunk portion 12b of the guide member 11 (arrow b). As a result, the locking portion 8a of the engagement receiver 8 engages with the receiver 10 and is fixed by the action of the toggle mechanism.

【0014】 次に、係合を解放するためには、上記と逆の操作を行う。トグルレバー4を逆 に回動(矢印c)させることにより、連結部材6と係合具8は、ガイド長孔12 に案内されて、外側方向に移動し(矢印d)、係止部8aは受具10から外れ、 外側に移動させられる。これにより、係合具8に邪魔されることなく、型枠体A と型枠体Bとの型開きを行うことができることになる。Next, in order to release the engagement, an operation reverse to the above is performed. By rotating the toggle lever 4 in the opposite direction (arrow c), the connecting member 6 and the engaging tool 8 are guided by the guide elongated hole 12 and move outward (arrow d), and the locking portion 8a is released. It is disengaged from the receiver 10 and moved to the outside. As a result, the molds A and B can be opened without being obstructed by the engagement tool 8.

【0015】[0015]

【効果】【effect】

以上の構成により、本願考案によれば、操作杆の回動操作のみで、作動ロッド に取付けられた複数個の係合具と受具との係合と解放を自動的にいっせいに行う ことができる。したがって、従来のように一つ一つ係合具と受具を係合させた後 、操作杆の操作により締結する繁雑さなく、非常に作業性の向上が図られる。 With the above configuration, according to the present invention, it is possible to automatically engage and disengage the plurality of engaging members attached to the operating rod and the receiving member only by rotating the operating rod. . Therefore, the workability can be greatly improved without the complexity of engaging the engaging member and the receiving member one by one as in the conventional case and then fastening them by the operation of the operating rod.

【0016】 また、ガイド部材は、係合機構のそれぞれに、別個に取付けられるものではな く、単一のものであるため、部品点数を減らすことができる。したがって構造が 簡単であることから、作動の信頼性も高いものにすることができる。 さらに、ガイド部材が単一であるため、これのみを取り替えることにより、自 由に係合具のストロークを変えることができる効果もある。Further, since the guide member is not attached separately to each of the engagement mechanisms but is a single guide member, the number of parts can be reduced. Therefore, since the structure is simple, the operation reliability can be high. Further, since the guide member is single, it is possible to change the stroke of the engaging tool by changing only the guide member.
