Description
【０００１】[0001]
この考案は、コンクリート型枠の止め具に関し、主として、ビルやマンション などの建物の水平な梁の上側に設けられるコンクリート型枠を保持するのに用い られる。 The present invention relates to a concrete formwork stopper, and is mainly used for holding a concrete formwork provided above a horizontal beam of a building such as a building or an apartment.
【０００２】[0002]
鉄筋コンクリート製の建物を建てるときには、水平な梁となるＨ形鋼の上面に 、外側に向けて設定された寸法だけ突出される外壁保持用の断面Ｌ形材を固定し 、この断面Ｌ形材の垂直部から２０〜３０mm程度内側の水平部に、長さの短い複 数個の鉄筋を間隔をあけて同一直線に溶接によって立設するとともに、これらの 鉄筋と断面Ｌ形材の垂直部との間に、コンクリート型枠が垂直に保持されていた 。 When building a building made of reinforced concrete, fix an L-shaped section for holding an outer wall, which is projected outward by a set dimension, on the upper surface of an H-shaped steel that will be a horizontal beam. A plurality of short reinforcing bars are erected by welding on the same straight line at intervals in the horizontal part 20 to 30 mm inward from the vertical part, and these reinforcing bars and the vertical part of the L-shaped section are In the meantime, the concrete formwork was held vertically.
【０００３】 そして、コンクリート型枠の内側の水平な梁に保持されたデッキプレートの上 側に床面となるコンクリートを打ち、このコンクリートが固化したのちコンクリ ート型枠を取り除き、床面となるコンクリートの端面と断面Ｌ形材の垂直部との 間にモルタルを充填し、最後に、壁材としてのＡＬＣ板（気泡を含むコンクリー ト製板材）が断面Ｌ形材の垂直部外側面に当接して取り付けられていた。Then, concrete which becomes the floor surface is struck on the upper side of the deck plate held by horizontal beams inside the concrete formwork, and after this concrete has solidified, the concrete formwork is removed to become the floor surface. Mortar is filled between the end face of the concrete and the vertical part of the L-shaped section, and finally the ALC plate (concrete plate containing air bubbles) as a wall material is applied to the outer surface of the vertical part of the L-shaped section. It was attached in contact.
【０００４】[0004]
しかしながら、コンクリート型枠を梁の上面に保持する従来のやり方では、梁 となるＨ形鋼に固着された断面Ｌ形材の上面に、間隔をあけて複数個の鉄筋を溶 接によって立設しなければならなくなるが、この溶接は高さが高くて足場が悪い 各階層に溶接機を引き上げて行わねばならないため、溶接に要する工数が多くな って費用が著しく割高になるだけでなく、作業を安全な状態で能率良く行うこと ができなかった。 However, according to the conventional method of holding the concrete formwork on the upper surface of the beam, a plurality of reinforcing bars are erected by welding at intervals on the upper surface of the L-shaped section having the H-shaped steel to be the beam. However, this welding has to be carried out by raising the welding machine to each floor, which is high in height and poor in footing. Could not be carried out efficiently and safely.
【０００５】 また、コンクリート型枠が取り外されたコンクリートの端面や断面Ｌ形材には 、壁材としてのＡＬＣ板を取り付けるボルトその他の締め付け部材を保持する保 持部が設けられていないため、ＡＬＣ板を少ない工数によって割安に、かつ能率 良く取り付けることができなかった。Further, since the end face of the concrete from which the concrete formwork has been removed and the L-shaped section have no holding portion for holding bolts and other tightening members for attaching the ALC plate as the wall material, the ALC is not provided. It was not possible to attach the board inexpensively and efficiently with a small number of man-hours.
【０００６】 この考案はこれらの事情に鑑みてなされたもので、コンクリート型枠を断面Ｌ 形材に少ない工数によって割安に、かつ安全に保持することができるようにする とともに、壁材としてのＡＬＣ板の取り付けを容易にできるようにしたコンクリ ート型枠の止め具の提供を目的としたものである。The present invention has been made in view of these circumstances, and makes it possible to hold a concrete formwork to an L-shaped section member in a low cost and safely with a small number of steps, and to use ALC as a wall member. The purpose of the invention is to provide a fastener for a concrete form that enables easy attachment of plates.
【０００７】[0007]
この考案は、前記目的を達成すべくなされたもので、板材を切り抜いて形成さ れ、かつ、コンクリート型枠を断面Ｌ形材に保持するコンクリート型枠の止め具 であって、第１脚部と第２脚部とは、断面Ｌ形材の垂直部を跨ぐ間隔を開けて形 成され、第１脚部と第２脚部の各上端部は、容易に切断し得る程度に細幅の連接 部によって連接され、第２脚部は上端が上方に延設されて型枠支持部が形成され 、下端は第１脚部から離れる方向に突設されるとともに、この突設部先端から上 向きに型枠挟持部が延設され、第２脚部と型枠挟持部との間に、コンクリート型 枠を支持し得る凹部が形成されてなることを特徴とするコンクリート型枠の止め 具としたものである。 The present invention has been made in order to achieve the above-mentioned object, and is a stopper for a concrete formwork which is formed by cutting out a plate material and which holds the concrete formwork in an L-shaped section, in which the first leg portion is provided. And the second leg are formed with a space extending across the vertical portion of the L-shaped section, and the upper ends of the first leg and the second leg are narrow enough to be easily cut. The second leg is connected by the connecting part, the upper end of the second leg is extended upward to form a formwork supporting part, and the lower end of the second leg is protruded in a direction away from the first leg. A fixture for a concrete formwork, characterized in that a formwork holding part is extended in a direction, and a recess capable of supporting the concrete formwork is formed between the second leg part and the formwork holding part. It was done.
【０００８】[0008]
コンクリート型枠の止め具は、第１脚部と第２脚部との間に断面Ｌ形材の係止 空間部が形成されるとともに、止め具の型枠挟持部と断面Ｌ形材との間に壁材（ ＡＬＣ板）を取り付けるボルトその他の締め付け具を保持する空間部を形成する から、複数個の止め具を断面Ｌ形材の垂直部を跨ぐように取り付けると、コンク リート型枠は、これらの止め具の第２脚部と型枠挟持部との間の空間部に垂直に 保持することが可能となる。 The fastener of the concrete formwork has a locking space portion having an L-shaped cross section formed between the first leg portion and the second leg portion, and at the same time, the frame holding portion of the fastener and the L-shaped cross section member of the fastener are formed. Since a space for holding bolts and other fasteners for attaching the wall material (ALC plate) is formed between them, if multiple fasteners are attached so as to straddle the vertical portion of the L-shaped section, the concrete formwork It becomes possible to hold the stopper vertically in the space between the second leg portion and the form clamping portion.
【０００９】 また、打設されたコンクリートが固化したのちにコンクリート型枠を取り外す と、止め具の第１脚部はコンクリートに保持された状態で断面Ｌ形材から外側に 突出されるが、この第１脚部は細幅の連接部によって第２脚部に連接されている ので、第１脚部は第２脚部との連接部によって容易に切断することができる。 しかも、断面Ｌ形材と固化したコンクリートの端面との間には空間部が形成さ れているので、この空間部に壁材（ＡＬＣ板）取り付け用の締め付け具の折り曲 げ部を挿入すると、この締め付け具により壁材（ＡＬＣ板）の取り付けが容易と なる。Further, when the concrete formwork is removed after the cast concrete has solidified, the first leg portion of the stopper is projected to the outside from the L-shaped cross section while being held by the concrete. Since the first leg is connected to the second leg by the narrow connecting portion, the first leg can be easily cut by the connecting portion with the second leg. Moreover, since a space is formed between the L-shaped cross section and the end surface of the solidified concrete, when the bending part of the fastener for attaching the wall material (ALC plate) is inserted into this space. By this tightening tool, the wall material (ALC plate) can be easily attached.
【００１０】[0010]
以下、この考案に係る実施例を図面に基づいて説明する。 図１ないし図５はこの考案の一実施例を示したもので、コンクリート型枠の止 め具１は、板材を切り抜いて形成された第１脚部２と第２脚部３とから主として 構成されている。 An embodiment according to the present invention will be described below with reference to the drawings. 1 to 5 show an embodiment of the present invention, in which a concrete mold stopper 1 is mainly composed of a first leg portion 2 and a second leg portion 3 formed by cutting out a plate material. Has been done.
【００１１】 第１脚部２と第２脚部３は、断面Ｌ形材６の垂直部６ｂの厚さと等しいか、こ の厚さよりわずかに大きな寸法を隔てて平行に配設され、それらの各上端部は、 容易に切断し得る程度の細幅の寸法を有する連接部４によって連接されている。 第２脚部３の上端は、上方に延設されてコンクリート型枠７を支持する型枠支持 部３ａが形成され、第２脚部３の下端には、第１脚部２から離れる方向に突設部 ３ｂが突設され、この突設部３ｂの先端に上向きに延設される型枠挟持部３ｃが 形成されている。この場合、第２脚部３と型枠挟持部３ｃとの間に形成される凹 部５は、コンクリート型枠７を丁度挿入し得る幅寸法に決められる。The first leg portion 2 and the second leg portion 3 are arranged parallel to each other with a dimension equal to or slightly larger than the thickness of the vertical portion 6b of the L-shaped section 6 in cross section. Each upper end portion is connected by a connecting portion 4 having a narrow dimension that can be easily cut. Formed at the upper end of the second leg 3 is a form supporting part 3a extending upward to support the concrete form 7, and at the lower end of the second leg 3 in a direction away from the first leg 2. The projecting portion 3b is projectingly provided, and a mold holding portion 3c extending upward is formed at the tip of the projecting portion 3b. In this case, the concave portion 5 formed between the second leg portion 3 and the mold holding portion 3c has a width dimension that allows the concrete mold 7 to be inserted therein.
【００１２】 次に、上記構成のコンクリート型枠の止め具１を用いた場合のコンクリート型 枠７の保持について説明する。 図２は、この実施例に係るコンクリート型枠の止め具１が、ビルやマンション などの建設現場の各階層に使用されている状態を示したものである。８は梁とし て用いられたＨ形鋼で、このＨ形鋼８の上面には、その長さ方向に前記した断面 Ｌ形材６が固着されたのち、断面Ｌ形材６の水平部６ａの上側に、建物の各階を 仕切るデッキプレート９が断面Ｌ形材６と直角をなす方向に固定されている。Next, the holding of the concrete formwork 7 when using the concrete formwork stopper 1 having the above-described configuration will be described. FIG. 2 shows a state where the concrete formwork stopper 1 according to this embodiment is used in each floor of a construction site such as a building or an apartment. Reference numeral 8 denotes an H-shaped steel used as a beam. The L-shaped member 6 having the above-mentioned cross-section is fixed to the upper surface of the H-shaped steel 8 in the lengthwise direction thereof, and then the horizontal portion 6a of the L-shaped member 6 is provided. A deck plate 9 for partitioning each floor of the building is fixed on the upper side of the building in a direction perpendicular to the L-shaped cross section 6.
【００１３】 コンクリート型枠の止め具１は、デッキプレート９の凹部９ａと対応する位置 において、連設部４の下側の空間部で断面Ｌ形材６の垂直部６ｂを跨ぐように装 着される。デッキプレート９の凹部９ａは、設定された間隔をもって連続して形 成されているが、コンクリート型枠の止め具１は、デッキプレート９の各凹部９ ａ毎に必ずしも装着する必要がないため、前記止め具１の取り付け間隔は、デッ キプレート９の隣接する凹部９ａ，９ａの間隔と必ずしも一致するとは限らない 。The fixture 1 of the concrete formwork is mounted so as to straddle the vertical portion 6b of the L-shaped section 6 in the space below the connecting portion 4 at a position corresponding to the recess 9a of the deck plate 9. To be done. Although the recesses 9a of the deck plate 9 are continuously formed at a set interval, the concrete mold stopper 1 does not necessarily have to be mounted in each recess 9a of the deck plate 9, The mounting interval of the stopper 1 does not always match the interval between the adjacent recesses 9a, 9a of the deck plate 9.
【００１４】 断面Ｌ形材６の長さ方向に適当な間隔を開けてコンクリート型枠の止め具１を 複数個装着すると、これらの第２脚部３と型枠保持部３ｃとによって形成される 複数個の凹部５は、一直線上に配列される。それ故、これらの凹部５の上側から コンクリート型枠７を嵌挿すると、コンクリート型枠７は、複数個のコンクリー ト型枠の止め具１によってほぼ垂直状態に保持され、断面Ｌ形材６に対するコン クリート型枠７の位置は、使用するコンクリート型枠の止め具１を適当に選ぶこ とにより位置決めすることができる。When a plurality of concrete mold stoppers 1 are mounted at appropriate intervals in the length direction of the L-shaped section 6 and formed, these second leg portions 3 and the mold holding portion 3c form these. The plurality of recesses 5 are arranged in a straight line. Therefore, when the concrete formwork 7 is inserted from the upper side of these recesses 5, the concrete formwork 7 is held in a substantially vertical state by the fasteners 1 of the plurality of concrete formwork, and the concrete formwork 7 with respect to the L-shaped section 6 is provided. The concrete formwork 7 can be positioned by appropriately selecting the fastener 1 of the concrete formwork to be used.
【００１５】 複数個のコンクリート型枠７が設定された位置で垂直状態に保持されると、コ ンクリート型枠７の内側にコンクリートＡが打ち込まれる。コンクリートＡが固 化したのち、コンクリート型枠７を上方に引き抜いて取り除く。この状態では、 コンクリート型枠の止め具１は、型枠挟持部３ｃの部分でコンクリートＡによっ て保持され、第１脚部２は断面Ｌ形材６より前方に突出されて後工程の作業の妨 げとなる。しかしながら、第１脚部２は細幅の連設部４を介して断面Ｌ形材６の 内側に位置する第２脚部３と連設されているので、第１脚部２と連設部４は、連 設部４が第２脚部３と連設される部分で切断することにより容易に取り除くこと ができ、後工程の作業の妨げとならないようにするとができる。When a plurality of concrete forms 7 are held vertically at set positions, concrete A is poured into the inside of the concrete form 7. After the concrete A is solidified, the concrete form 7 is pulled out and removed. In this state, the concrete mold stopper 1 is held by the concrete A at the mold clamping portion 3c, and the first leg 2 is projected forward from the L-shaped cross-section 6 to perform the work in the post-process. It will prevent However, since the first leg 2 is continuously connected to the second leg 3 located inside the L-shaped member 6 through the narrow width continuous portion 4, the first leg 2 and the first leg 2 are connected to each other. 4 can be easily removed by cutting the connecting portion 4 at a portion where the connecting portion 4 is connected to the second leg portion 3, so that it does not hinder the work of the subsequent process.
【００１６】 しかも、コンクリート型枠７が取り除かれた状態では、断面Ｌ形材６の垂直部 ６ｂとコンクリートＡの端面Ｂとの間に設定された寸法の空間部が形成されるの で、この空間部に逆Ｌ形に折り曲げられた複数個のねじ（その他の締め付け具で もよい）１０の基端部を装着することができる。このため、断面Ｌ形材６の垂直 部６ｂから外側に突出する複数個のねじ１０の先端側に、壁材（ＡＬＣ板）１１ に設けられた複数個のばか穴１２を挿通させると、ワッシャー１３とナット１４ とにより、壁材（ＡＬＣ板）１１を断面Ｌ形材６にきわめて能率良く取り付ける ことができる。Moreover, when the concrete formwork 7 is removed, a space portion having a set dimension is formed between the vertical portion 6b of the L-shaped section 6 and the end surface B of the concrete A. It is possible to mount the base ends of a plurality of screws (other tightening tools may be used) 10 bent in an inverted L shape in the space. For this reason, when the plurality of fool holes 12 provided in the wall material (ALC plate) 11 are inserted into the tip ends of the plurality of screws 10 protruding outward from the vertical portion 6b of the L-shaped cross-section member 6, the washer is The wall material (ALC plate) 11 can be attached to the L-shaped cross-section member 6 very efficiently by means of the nut 13 and the nut 14.
【００１７】 図６ないし図８は、この考案の他の実施例を示したもので、コンクリート型枠 の止め具１Ａは、板材を切り抜いて形成された第１Ｖ形脚部２Ａと第２Ｖ形脚部 ３Ａとを主構成要素としている。 第１Ｖ形脚部２Ａは、連設部４ａの部分で逆Ｖ字形に結合された第１主脚部２ Ａ1 と第１補助脚部２Ａ2 とからなり、第２Ｖ形脚部３Ａは、同じく連設部４ａ の部分で逆Ｖ字形に結合された第２主脚部３Ａ1 の下端には、第１主脚部２Ａ1 から離れる方向に突設部３Ｂが突設され、この突設部３Ｂの先端に上向きに延設 される型枠挟持部３Ｃが形成されている。型枠支持部３ａは、第２補助脚部３Ａ 2 の上端をくの字に折り曲げて上向きに延設されているが、第２主脚部３Ａ1 の 上端から上向きに延設してもよい。6 to 8 show another embodiment of the present invention, in which a concrete mold stopper 1A has a first V-shaped leg 2A and a second V-shaped leg formed by cutting out a plate material. Part 3A is the main constituent element. The first V-shaped leg portion 2A is a first main leg portion 2A which is connected in an inverted V-shape at the connecting portion 4a.1And the first auxiliary leg 2A2And the second V-shaped leg portion 3A is the second main leg portion 3A which is also connected to the inverted V-shape at the portion of the continuous portion 4a.1At the lower end of the first main leg 2A1 A projecting portion 3B is projected in a direction away from the projecting portion 3B, and a mold holding portion 3C extending upward is formed at the tip of the projecting portion 3B. The formwork support portion 3a includes a second auxiliary leg portion 3A. 2 The upper end of each of the second main leg portions 3A is bent upward and extends upward.1You may extend upwards from the upper end of.
【００１８】 上記構成のコンクリート型枠の止め具１Ａを、図７に示すように、断面Ｌ形材 ６の垂直部６ｂを跨ぐように複数個装着すると、前記の各止め具１Ａは、断面Ｌ 形材６の垂直部６ｂの片面に逆Ｖ字形をなす第１主脚部２Ａ1 と第１補助脚部２ Ａ2 とにより接触し、垂直部６ｂの他面に逆Ｖ字形をなす第２主脚部３Ａ1 と第 ２補助脚部３Ａ2 とにより接触するため、断面Ｌ形材６に装着される止め具１Ａ のがたつきを前記実施例の場合より少なくすることができる。 したがって、この実施例のコンクリート型枠の止め具１Ａを用いる場合には、 前記実施例について述べた作用効果に加えてコンクリート型枠７のがたつきを少 なくし、ねじ１０の折り曲げ基端部が装着される断面Ｌ形材６とコンクリートＡ の端面Ｂとの間隔をより高い精度に仕上げることができる。As shown in FIG. 7, when a plurality of fasteners 1A of the concrete form having the above-described structure are mounted so as to straddle the vertical portion 6b of the L-shaped section 6, each of the above-mentioned fasteners 1A has a section L The first main leg portion 2A 1 and the first auxiliary leg portion 2 A 2 each having an inverted V shape are in contact with one surface of the vertical portion 6b of the shape member 6 and the second portion having an inverted V shape is provided on the other surface of the vertical portion 6b. Since the main leg portion 3A 1 and the second auxiliary leg portion 3A 2 are in contact with each other, the rattling of the stopper 1A mounted on the L-shaped cross-section member 6 can be reduced as compared with the above-mentioned embodiment. Therefore, when the concrete form stopper 1A of this embodiment is used, the rattling of the concrete form 7 is reduced and the bending base end portion of the screw 10 is reduced in addition to the effects described in the above embodiments. It is possible to finish the gap between the L-shaped section 6 to be mounted and the end face B of the concrete A 1 with higher accuracy.
【００１９】 図９は、この考案のさらに他の実施例を示したもので、コンクリート型枠の止 め具１Ｂは、連結部４ａの一側（図９における左側）を第１実施例（図１参照） における第１脚部２と同じ構成にし、連結部４ａの反対側を第２実施例（図６参 照）における連結部４ａの右側と全く同じ構成にした場合である。 この場合のコンクリート型枠の止め具１Ｂを用いる場合には、断面Ｌ形材６の 垂直部６ｂに装着された止め具１Ｂは、垂直部６ｂの片面に接触する第１脚部２ と、垂直部６ｂの他面に逆Ｖ字形をなす方向に接触する第２主脚部３Ａ1 および 第２補助脚部３Ａ2 の３個所により安定した状態に保持されるから、第２実施例 （図６参照）の場合に比べてより簡単な構成により、製作コストを割安にするこ とができる。FIG. 9 shows still another embodiment of the present invention, in which a concrete form stopper 1B has one side (the left side in FIG. 9) of the connecting portion 4a as the first embodiment (see FIG. 1)), and the opposite side of the connecting portion 4a is completely the same as the right side of the connecting portion 4a in the second embodiment (see FIG. 6). In the case of using the concrete mold stopper 1B in this case, the stopper 1B attached to the vertical portion 6b of the L-shaped cross-section 6 has the first leg 2 that contacts one side of the vertical portion 6b and the vertical leg 6b. Since the second main leg portion 3A 1 and the second auxiliary leg portion 3A 2 which are in contact with the other surface of the portion 6b in the reverse V-shape are held in a stable state, the second embodiment (FIG. 6). The manufacturing cost can be reduced by the simpler configuration than the case of (see).

以上詳述したように、この考案によれば、次に記載するすぐれた作用効果を奏 する。 As described in detail above, according to this invention, the following excellent operational effects are exhibited.
【００２１】 請求項１に記載のコンクリート型枠の止め具においては、細幅の連設部によっ て上端部を連設された第１脚部と第２脚部の間に、断面Ｌ形材の垂直部を跨ぐ間 隔が形成されるとともに、第２脚部と、その下端部から突設される突設部と、こ の突設部先端の型枠挟持部とによりコンクリート型枠を保持する凹部が形成され ているため、コンクリート型枠の止め部は断面Ｌ形材の垂直部に能率肉装着でき る上に、複数個の止め具を装着するだけの安全な作業で、一直線上に配列される 第２脚部と型枠挟持部との間の凹部により、コンクリート型枠を設定された位置 にきわめて容易に保持して作業の能率を向上することができる。In the concrete form stopper according to claim 1, an L-shaped cross section is provided between a first leg and a second leg whose upper ends are continuously connected by a narrow width connecting portion. A space is formed that straddles the vertical portion of the material, and the concrete formwork is formed by the second leg part, the projecting part projecting from the lower end part thereof, and the form clamping part at the tip of this projecting part. Since the holding recess is formed, the concrete formwork stop can be efficiently attached to the vertical part of the L-shaped section, and it is a safe work just to attach a plurality of stops, and it can be aligned on a straight line. Due to the concave portion between the second leg portion and the form clamping portion arranged in the, the concrete formwork can be very easily held at the set position to improve the work efficiency.
【００２２】 また、コンクリート型枠が取り除かれたとき、断面Ｌ形材より外側に突出して 邪魔者となっている第１脚部の部分は、第２脚部と連設されている細幅の連設部 で切断することにより、きわめて容易に除去することができる。 その上、コンクリート型枠を取り除いた状態では、断面Ｌ形材と打設されたコ ンクリートの端面との間に設定された寸法の空間部が形成されるので、この空間 部に壁材を固定するねじのＬ形に折り曲げられた基端部を装着すると、このねじ の先端部を利用して壁材（ＡＬＣ板）をきわめて能率良く取り付けることができ る。Further, when the concrete formwork is removed, the portion of the first leg portion that protrudes outward from the L-shaped section and becomes an obstacle, has a narrow width that is continuous with the second leg portion. It can be removed very easily by cutting at the connecting part. In addition, when the concrete formwork is removed, a space with a set size is formed between the L-shaped section and the end face of the concrete that has been placed, so the wall material is fixed in this space. By attaching the L-shaped base end of the screw, the wall material (ALC plate) can be attached very efficiently using the tip of this screw.
【００２３】 請求項２に記載のコンクリート型枠の止め具においては、第１脚部は第１主脚 部と第１補助脚部とを連設部の部分で逆Ｖ字形に結合した第１Ｖ形脚部に形成さ れ、第２脚部は第２主脚部と第２補助脚部とを連設部の部分で逆Ｖ字形に結合し た第２Ｖ形脚部に形成されるとともに、型枠支持部は第２補助脚部または第２主 脚部に対してくの字形に変形して上向きに延設されているので、コンクリート型 枠の止め具は、断面Ｌ形材の垂直部に装着されたとき、それらの両面をそれぞれ Ｖ字形に形成された第１Ｖ形脚部と第２Ｖ形脚部とにより、より確実に保持され 、コンクリート型枠の位置決め精度を向上することができる。In the concrete form fixture according to claim 2, the first leg is a first V in which the first main leg and the first auxiliary leg are connected in an inverted V-shape at the connecting portion. The second leg is formed into a second V-shaped leg in which the second main leg and the second auxiliary leg are connected in an inverted V shape at the connecting portion, and Since the formwork support is deformed into a dogleg shape with respect to the second auxiliary leg or the second main leg and extends upward, the fastener of the concrete formwork is placed in the vertical part of the L-shaped section. When mounted, the first V-shaped leg portion and the second V-shaped leg portion, both sides of which are formed in V-shape, respectively, are more reliably held and the positioning accuracy of the concrete formwork can be improved.
【００２４】 請求項３に記載のコンクリート型枠の止め具においては、第２脚部のみが第２ 主脚部と第２補助脚部とを連設部の部分で逆Ｖ字形に結合した第２Ｖ形脚部に形 成されるとともに、型枠支持部は第２補助脚部または第２主脚部に対してくの字 形に変形して上向きに延設されているので、請求項２に記載の構成の場合に比べ てより簡単な構成により、コンクリート型枠の止め具を断面Ｌ形材の垂直部に確 実に保持させることができる。In the concrete formwork stopper according to claim 3, only the second leg has the second main leg and the second auxiliary leg connected to each other in an inverted V-shape at the connecting portion.
