本考案はコンクリート型枠を組み立てるための保持金具に係り、特に作業効率 を向上させる技術に関する。 The present invention relates to a holding metal fitting for assembling a concrete formwork, and particularly to a technique for improving work efficiency.

【０００２】[0002]

【従来の技術】[Prior art]

コンクリート建築における型枠の成形は、従来一般に図３に示すような保持金 具を用いてなされる。この保持金具１は、型枠パネル２，３を抑えるＰコーン部 材４とＫＰコーン部材５を備え、またＰコーン部材４およびＫＰコーン部材５を 連結する丸セパレータ６を中間に備える。また、Ｐコーン部材４とＫＰコーン部 材５にはそれぞれ単寸の軸本体７，８を螺合させ、この軸本体７，８の外側に軸 脚９，１０を螺合させ型枠パネル２，３を組み立てる。 Forming of a formwork in a concrete building is conventionally generally performed using a holding metal fixture as shown in FIG. The holding metal fitting 1 includes a P-cone member 4 and a KP-cone member 5 that hold down the formwork panels 2 and 3, and a round separator 6 that connects the P-cone member 4 and the KP-cone member 5 in the middle. Further, the P cone member 4 and the KP cone member 5 are respectively screwed with single-sized shaft main bodies 7 and 8, and shaft legs 9 and 10 are screwed onto the outsides of the shaft main bodies 7 and 8 to form frame panel 2 , 3, assemble.

【０００３】 この場合、型枠パネル２，３は、それぞれＰコーン４およびＫＰコーン５の外 側に位置し、さらにＫＰコーン５側の型枠パネル３の外側には断熱材１１が配さ れるのが一般である。断熱材１１が配される肉厚のぶんだけ、ＫＰコーン５側の 軸本体８は軸本体７よりも長寸に設計される。In this case, the formwork panels 2 and 3 are located outside the P cone 4 and the KP cone 5, respectively, and the heat insulating material 11 is arranged outside the formwork panel 3 on the KP cone 5 side. Is common. The shaft body 8 on the KP cone 5 side is designed to be longer than the shaft body 7 by the thickness of the heat insulating material 11.

【０００４】 この保持金具１の軸中心をなす丸セパレータ６および軸本体７，８は金属で成 形され、それぞれＰコーン４およびＫＰコーン５に螺合できるよう雄ネジが切っ てあり、また金属成形された軸脚９，１０の端部雌ネジに螺合できるよう、軸本 体７，８の外側端部には雄ネジが切ってある。The circular separator 6 and the shaft main bodies 7 and 8 that form the shaft center of the holding metal fitting 1 are made of metal, and have male threads cut so that they can be screwed into the P cone 4 and the KP cone 5, respectively. Male threads are formed on the outer ends of the shaft bodies 7 and 8 so that they can be screwed into the female threads at the ends of the molded shaft legs 9 and 10.

【０００５】 コンクリート型枠を組み立てるに際しては、丸セパレータ６中心として型枠内 にＰコーン４およびＫＰコーン５を螺合配置し、型枠パネル２の外側から軸本体 ７，８を、それぞれＰコーン４とＫＰコーン５の雌ネジ部に嵌入螺合し、さらに 軸本体７，８の両端雌ネジに対して、軸脚９，１０の雄ネジを嵌入螺合させるよ うになっている。尚、コンクリート型枠の組立作業性を向上させる技術としては 従来例えば、実開昭５８−１２３１５６、特開平４−１１５０５５号がある。When assembling the concrete formwork, the P cone 4 and the KP cone 5 are screwed in the form centering on the round separator 6, and the shaft bodies 7 and 8 are respectively attached from the outside of the formwork panel 2 to the P cone. 4 and the KP cone 5 are fitted and screwed into female threads of the KP cone 5, and male threads of the shaft legs 9 and 10 are fitted and screwed into female threads at both ends of the shaft bodies 7 and 8. Incidentally, as a technique for improving the workability of assembling a concrete formwork, there are, for example, Japanese Utility Model Laid-Open No. 58-123156 and JP-A-4-115055.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、かかる従来の保持金具は、作業性が悪く建築コストを上昇させると いう問題がある。 By the way, such a conventional holding metal has a problem that workability is poor and construction cost is increased.

【０００７】 作業性を低下させるのは丸セパレータを中心とした部品パーツが多数に分割さ れ、それぞれを隣接する接続パーツと螺合させる必要があるためである。The workability is reduced because the component parts centering on the round separator are divided into a large number, and it is necessary to screw each of them into the adjacent connecting parts.

【０００８】 また建築現場におけるネジ部品の組付作業は、簡単に機械化することは困難で あり、作業時間を短縮することもできない。また型枠の組立作業時には、両側か ら複数部品の螺合作業を行うため、どうしても型枠パネルの両側にそれぞれ作業 スタッフを配さなければならず、作業人員を削減することもできない。Further, the work of assembling the screw parts at the construction site is difficult to mechanize easily, and the work time cannot be shortened. In addition, when assembling the formwork, multiple parts are screwed together from both sides, so it is inevitable that a work staff member must be provided on each side of the formwork panel, and it is not possible to reduce the workforce.

【０００９】 また部品パーツが多数あるため、当然、各パーツごとの成形コストが必要とな るわけで、全体としての保持金具コストが上昇し、建築に要するコストを押し上 げる。Further, since there are many component parts, of course, a molding cost for each part is required, which raises the cost of the holding metal fitting as a whole and pushes up the cost required for construction.

【００１０】 そこで本考案の目的は、型枠保持部材の作業性を向上させる一方で、当該保持 部材の製造コストをより低減させる点にある。Therefore, an object of the present invention is to improve the workability of the mold holding member and further reduce the manufacturing cost of the holding member.

【００１１】[0011]

【課題を解決するための手段】[Means for Solving the Problems]

前記目的を達成して課題を達成するため、本考案に係るコンクリート型枠の保 持部材は、型枠の肉厚寸法に応じて長寸を設定した軸部材と、該軸部材に挿通可 能な開孔を備える鍔部材からなり、軸部材の両端に雌ネジを設ける一方、該雌ネ ジから所定寸法離隔させた位置に前記鍔部材の動きを規制するストッパ部を設け た。 In order to achieve the above object and to achieve the object, a holding member for a concrete formwork according to the present invention can be inserted into the shaft member whose length is set according to the wall thickness of the formwork. The shaft member is provided with female screws at both ends thereof, and stopper portions for restricting the movement of the flange member are provided at positions separated from the female screw by a predetermined dimension.

【００１２】[0012]

【作用】 この保持部材は型枠の肉厚寸法に応じた長さをもつ軸部材が、従来の金具にお ける丸セパレータと軸本体と同様に、軸中心をなす部材として機能する。また、 軸部材に挿通可能な開孔をもった鍔部材を軸部材両端から嵌め入れるが、軸部材 の所定位置にはストッパ部を設けてあり、鍔部材は、その場所から内側（軸中央 方向）へは動かない。このため鍔部材はコンクリートパネルを確実に抑え、従来 の金具におけるＰコーンおよびＫＰコーンと同じ機能を営む。軸部材の両端部に は雌ネジが切ってある。この雌ネジの部分には、従来使用されていた軸脚を螺合 させ、型枠パネルの組付を完了する。In this holding member, the shaft member having a length corresponding to the thickness dimension of the mold works as a member that forms the shaft center, like the round separator and the shaft body in the conventional metal fitting. Further, a collar member having an opening through which the shaft member can be inserted is fitted from both ends of the shaft member, but a stopper portion is provided at a predetermined position of the shaft member, and the collar member is located inward from the position (in the axial center direction). ) Does not move. For this reason, the brim member securely holds down the concrete panel and performs the same function as the P cone and KP cone in the conventional metal fittings. Female threads are formed on both ends of the shaft member. A shaft leg that has been conventionally used is screwed into this female screw portion, and the assembling of the form panel is completed.

【実施例】【Example】

以下、添付図面に基づいて本考案の実施例を説明する。 図１は本考案に係る型枠パネルの保持部材の一例を示すものである。 この保持部材２０は、一本の軸部材２１と、二つの鍔部材３１，３２とからな る。軸部材２１は、その両端部を細径に成形し、端部に雌ネジ２５，２６を切っ てある。軸部材２１の径寸は、例えば中央の太い部分（Ｆ）を９ｍｍ、両端の細 い部分（Ｓ）を７ｍｍ程度に設定する。この径の違いによって、細径部分と太径 部分との境には、リング状の段差部２７，２８が出来る。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a holding member for a formwork panel according to the present invention. The holding member 20 is composed of one shaft member 21 and two collar members 31 and 32. Both ends of the shaft member 21 are formed to have a small diameter, and female screws 25 and 26 are cut at the ends. The diameter of the shaft member 21 is set to, for example, 9 mm at the central thick portion (F) and about 7 mm at both end thin portions (S). Due to this difference in diameter, ring-shaped step portions 27 and 28 are formed at the boundary between the small diameter portion and the large diameter portion.

【００１４】 軸部材２１の長さは、建築しようとする壁厚に応じ適宜設定する。この軸部材 ２１は、組み立てた型枠にコンクリートを打設するまでのあいだ型枠を抑えてい るだけの剛性があれば良いから、従来の保持金具のように鋼棒に限らず、ＦＲＰ 等の樹脂系素材を用いて構わない。耐アルカリ性のある樹脂系素材であれば、鋼 棒を使用するよりもコンクリートの劣化を確実に防止できる。また樹脂系素材で あれば、軽量であり搬入作業も効率的となる。The length of the shaft member 21 is appropriately set according to the wall thickness to be constructed. This shaft member 21 need only be rigid enough to hold down the formwork until concrete is cast into the assembled formwork. Therefore, it is not limited to steel rods like the conventional holding metal fittings, but also FRP and the like. A resin material may be used. Alkali-resistant resin-based materials can prevent concrete deterioration more reliably than using steel rods. Also, if it is a resin-based material, it is light in weight and the loading work becomes efficient.

【００１５】 二つの鍔部材３１，３２は、ＦＲＰ等の樹脂系素材を使用する。鍔部材３１， ３２の大きさ（径寸）は問わないが、通常は２０〜４０ｍｍ程度に径寸を設定す る。鍔部材３１，３２は平板パネルとする。従来の型枠金具（Ｐコーン等）のよ うに、突起叉は凸形状を呈する部分をもたない。尚、その平面形状は円形に限ら ず適当な多角形としても良い。The two flange members 31, 32 are made of a resin material such as FRP. The size (diameter) of the collar members 31, 32 does not matter, but normally the diameter is set to about 20 to 40 mm. The collar members 31 and 32 are flat panels. It does not have a protrusion or a portion having a convex shape unlike the conventional form fittings (P cone, etc.). The plane shape is not limited to the circular shape and may be an appropriate polygonal shape.

【００１６】 鍔部材３１，３２の中央部に設ける開口３３，３４の径寸は、軸部材２１の両 端部から嵌め入れ可能な大きさがあり、段差部２７，２８の外径寸法を超えない 限り、特に限定されない。鍔部材３１，３２は、軸部材２１から嵌め入れて、ス トッパである段差部２７，２８の部分で位置決めさせたいからである。The diameters of the openings 33, 34 provided in the central portions of the collar members 31, 32 are such that they can be fitted from both ends of the shaft member 21, and exceed the outer diameters of the step portions 27, 28. Unless otherwise specified, it is not particularly limited. This is because the collar members 31 and 32 are to be fitted into the shaft member 21 and positioned at the step portions 27 and 28 which are stoppers.

【００１７】 この保持部材は、図２に示すように鍔部材３１，３２を軸部材２１の両端部か ら挿入した後、壁面の外側部分となる鍔部材３１の外方に型枠パネル４０を配置 させ、壁面の内側部分となる鍔部材３２の外方に断熱材４１および型枠パネル４ ２を位置させる。As shown in FIG. 2, this holding member is obtained by inserting the collar members 31 and 32 from both ends of the shaft member 21 and then placing the form panel 40 on the outside of the collar member 31 which is the outer portion of the wall surface. The heat insulating material 41 and the form panel 42 are positioned outside the flange member 32, which is the inner portion of the wall surface.

【００１８】 型枠パネル４０，４２からは軸部材２１の両端雌ネジ２５，２６が突出する。 この雌ネジ２５，２６には、従来から使用されている軸脚９，１０を螺合させ、 型枠を組付ける。型枠を完成した後、型枠内にはコンクリートを打設して養生さ せるが、コンクリート固化後には軸脚９，１０を外し、雌ネジ部２５，２６から 軸部材２１を切断する。軸部材２１を樹脂系素材で成形している場合には、その 切断差業は極めて容易である。Female screws 25, 26 at both ends of the shaft member 21 project from the formwork panels 40, 42. The shaft legs 9 and 10 which have been conventionally used are screwed into the female screws 25 and 26 to assemble the mold. After the formwork is completed, concrete is poured into the formwork to cure it, but after the concrete is solidified, the shaft legs 9 and 10 are removed, and the shaft member 21 is cut from the female screw parts 25 and 26. When the shaft member 21 is made of a resin material, the cutting operation is extremely easy.

【００１９】 従って、この保持部材によれば、軸脚９，１０以外の部材の螺合を要しないの で、極めて簡単にコンクリート型枠を組み立てることが出来る。Therefore, according to this holding member, since it is not necessary to screw members other than the shaft legs 9 and 10, the concrete form can be assembled very easily.

【００２０】 またこの保持部材は一本の軸部材２１と二つの鍔部材３１，３２とからなり、 また従来金具に較べて部品点数が格段に少なく、しかも各部の構成が単純である から、成形コストを格段に低減することが出来る。Further, this holding member is composed of one shaft member 21 and two collar members 31 and 32. Further, the number of parts is remarkably smaller than that of the conventional metal fittings, and the structure of each part is simple. The cost can be significantly reduced.

【００２１】 また各構成部品の形状を単純化できるので、運搬性、搬送性を格段に向上させ ることが出来る。Further, since the shape of each component can be simplified, it is possible to significantly improve the transportability and the transportability.

【００２２】 型枠パネルの取外し作業性でいうと、鍔部材３１，３２を取り外す必要がない ため、モルタル充填などの煩雑な作業を要せず、作業時間を格段に短縮すること が可能となる。すなわち、従来の保持金具ではＰコーン等形状を突出させた部品 を使用していたため型枠パネルの取り外し後は、コンクリート壁面に凹形の陥没 部ができた。この陥没部を埋めるためには、モルタルを充填し、そのうえからセ メントを塗布しなければならない。この作業を怠ると、陥没部から水分が侵入し コンクリート壁面の劣化を早める。一方、本考案に係る保持部材によれば、鍔部 材３１，３２が樹脂であり、また壁面に陥没箇所を作らないので取り外す必要も なく、上側から簡単にセメント（または外装タイル）を塗布するだけでよい。仮 に鍔部材３１，３２を金属成形した場合であっても、鍔部材３１，３２は平面的 であり深い陥没形状を作らない。金属製の鍔部材は取り外す必要があるが、その 部材が作る凹みは僅かなものであり、モルタルセメントの塗布作業も非常に簡単 である。In terms of workability of removing the formwork panel, since it is not necessary to remove the collar members 31 and 32, complicated work such as mortar filling is not required and the work time can be significantly shortened. . In other words, in the conventional holding metal fittings, parts having a protruding shape such as a P-cone were used, so that after the removal of the formwork panel, a concave depression was formed on the concrete wall surface. In order to fill this depression, mortar must be filled and then cement must be applied. If this work is neglected, water will penetrate from the depression and the deterioration of the concrete wall surface will be accelerated. On the other hand, according to the holding member of the present invention, since the collar members 31 and 32 are made of resin and the wall surface does not have a recessed portion, there is no need to remove them, and the cement (or exterior tile) is easily applied from the upper side. Just enough. Even if the flange members 31 and 32 are formed by metal, the flange members 31 and 32 are planar and do not form a deep depressed shape. The brim member made of metal needs to be removed, but the dent made by the member is very small, and the work of applying mortar cement is very easy.

【００２３】 尚、本考案に係る軸部材は、壁幅に応じて適宜その寸法を変更設定できること はいうまでもない。また鍔部材の位置を規制するストッパ部は、前記実施例のよ うな段差面に限らず、各種形状の突起、拡開部、ノッチ部等であっても良い。所 定位置で鍔部材の動きを拘束できる限りその手段を問わない。壁厚や使用する型 枠パネルあるいは断熱材肉厚に応じ、ストッパ位置を変更できることは勿論であ る。軸部材は内部を中空としても構わない。It is needless to say that the shaft member according to the present invention can be appropriately changed and set in size according to the wall width. Further, the stopper portion that regulates the position of the collar member is not limited to the stepped surface as in the above-described embodiment, but may be a protrusion of various shapes, an expanded portion, a notch portion, or the like. Any means can be used as long as the movement of the collar member can be restrained at a fixed position. Of course, the stopper position can be changed according to the wall thickness, the formwork panel used, or the thickness of the heat insulating material. The shaft member may have a hollow inside.
