Description

本発明はコンクリート製の構造物を施工する際に、そのものが構造物のコンクリート打設用の型枠として枠組され、打設コンクリートが固化後にコンクリート構造物の表面にそのまま残存するタイプの残存型枠に関し、特には、多数の貫通穴と裏面に多数の突起物を有する残存型枠に関する。   In the present invention, when a concrete structure is constructed, a residual formwork of the type in which the structure itself is framed as a formwork for placing concrete, and the cast concrete remains on the surface of the concrete structure after solidification. In particular, the present invention relates to a remaining mold having a large number of through holes and a large number of protrusions on the back surface.

従来、コンクリート製の構造物を施工する際に、構造物のコンクリート打設用の型枠として枠組し、打設コンクリートが固化後に、コンクリート構造物の表面にそのまま固着して残存し、型枠を取り外す必要のないコンクリート製の残存型枠が知られている。   Conventionally, when constructing a concrete structure, it is framed as a formwork for placing concrete in the structure, and after the cast concrete is solidified, it remains fixed and remains on the surface of the concrete structure. There are known residual forms of concrete that do not need to be removed.

そして、この残存型枠としては、主としてコンクリート製のプレート本体と、その内部に埋設した網状体,鉄筋,鉄線等の補強材とをベースにして、更にコンクリート構造物との固着性を高めるため、プレート本体の裏面側には種々の工夫が施されている。   And as this residual formwork, mainly based on a plate body made of concrete and a reinforcing material such as a net-like body, a reinforcing bar, a steel wire embedded in the interior, in order to further enhance the adhesion to the concrete structure, Various devices are applied to the back side of the plate body.

例えば、プレート本体の裏面に形鋼やループ状のフック金具等の金属製のものを突出して設けたもの、あるいは、特開平10−306461号のようにプレート本体(パネル)に多数の貫通穴を穿設したもの、また、特開2005−330755のように、型枠パネルの片面に多数の溝穴を形成したもの等がある。
特開平10−306461号公報 特開2005−330755号公報
For example, a metal body such as a shape steel or loop-shaped hook metal fitting is provided on the back surface of the plate body, or a large number of through holes are provided in the plate body (panel) as disclosed in JP-A-10-306461. There are those which are perforated, and those in which a number of slots are formed on one side of a formwork panel as disclosed in JP-A-2005-330755.
Japanese Patent Laid-Open No. 10-306461 JP-A-2005-330755

しかしながら、プレート本体の裏面から金属製の形鋼やフック金具等を突出するものは、形鋼やフック金具等を加工するのに手間を要し、残存型枠としての製造コストが高くなり、通常一つの施工現場で使用する残存型枠の枚数は多く、そのような高いコストの残存型枠を使用するとコンクリート構造物の施工コストも高くなる。   However, those that project metal shape steel or hook metal fittings from the back of the plate body require time and effort to process the shape steel or hook metal fittings, which increases the manufacturing cost as a residual formwork. The number of remaining molds used at one construction site is large, and the use of such high cost residual molds increases the construction cost of the concrete structure.

また、特開平10−306461号、特開2005−330755のものは、前記の金属製のものを使用せずに、平らなプレート本体に多数の貫通穴あるいは溝穴を穿設したものであるから製造コストが安い利点を有するが、単に多数貫通穴を穿設するとプレート本体(型枠パネル)の強度が低下するため、どうしてもプレート本体の厚さを大きくする必要が生じ、そのために全体の重量が増加し、コストの面及び運搬の面で不利となる等の問題点を有し、他方、溝穴のものはコンクリート打設時に、溝穴内に空気溜りが生じ易く、コンクリート構造物とプレート本体間に空洞が生じ易く、これによりプレート本体の脱落の原因ともなる等の問題点を有していた。   In addition, JP-A-10-306461 and JP-A-2005-330755 are those in which a large number of through holes or slots are formed in a flat plate body without using the above-mentioned metal one. Although it has the advantage of low manufacturing cost, the strength of the plate main body (formwork panel) decreases simply by drilling a large number of through holes, so it is necessary to increase the thickness of the plate main body. Increased and disadvantageous in terms of cost and transportation, etc. On the other hand, in the case of a slot, when a concrete is placed, an air pocket is likely to occur in the slot, and between the concrete structure and the plate body In this case, there is a problem that a cavity is easily formed in the plate body, thereby causing the plate body to fall off.

本発明は、上記問題点に鑑みこれを解消するものであり、つまり、コンクリート打設時に空気溜りが生じないと共に充填状態も確認でき、打設コンクリートとの固着性が高く、且つ、低コストで製造できる残存型枠を提供することを目的とする。   The present invention is to solve this problem in view of the above problems, that is, no air accumulation occurs at the time of concrete placement, and the state of filling can be confirmed, the adhesiveness with the placement concrete is high, and at low cost. The object is to provide a residual formwork that can be manufactured.

本発明の残存型枠は、コンクリート製で四角形状のプレート本体(1)と、そのプレート本体(1)に埋設した補強材(2)とから成る残存型枠において、前記プレート本体(1)の裏面(1a)に、コンクリート製の突起物(1c)を多数一体に形成すると共に、前記プレート本体(1)に多数の貫通穴(1d)を穿設し、且つ、前記裏面(1a)の少なくとも四隅にネジ用取付手段(3)を設ける。   The residual form of the present invention is a residual form consisting of a rectangular plate body (1) made of concrete and a reinforcing material (2) embedded in the plate body (1). A large number of concrete protrusions (1c) are integrally formed on the back surface (1a), a plurality of through holes (1d) are formed in the plate body (1), and at least the back surface (1a) is formed. Screw mounting means (3) are provided at the four corners.

前記突起物(1c)が、略半球,円錐台,円柱,角錐台,多角錐台等のいずれかであるのが好ましい。   It is preferable that the protrusion (1c) is any one of a substantially hemisphere, a truncated cone, a cylinder, a truncated pyramid, a polygonal truncated cone, and the like.

前記貫通穴(1d)が、前記突起物(1c)の中心に穿設するのが好ましい。   The through hole (1d) is preferably drilled in the center of the protrusion (1c).

前記ネジ用取付手段(3)が、インサートナット(31)であるのが好ましい。   The screw mounting means (3) is preferably an insert nut (31).

前記ネジ用取付手段(3)が、タッピンネジ用の取付片(32),(33)であるのが好ましい。   The screw mounting means (3) is preferably a tapping screw mounting piece (32), (33).

前記ネジ用取付手段(3)が、バカ穴(34)であるのが好ましい。   The screw mounting means (3) is preferably a hole (34).

本発明の請求項中におけるネジ用取付手段(3)とは、ボルトやタッピンネジ等を含むネジが螺合するためのインサートナット、取付片等を含むもの、あるいは、雄ネジ類が挿通可能なバカ穴をいう。   The screw mounting means (3) in the claims of the present invention includes an insert nut for attaching a screw including a bolt, a tapping screw or the like, an attachment piece or the like, or a fool through which male screws can be inserted. Say a hole.

本発明は、プレート本体(1)の裏面(1a)に、コンクリート製の突起物(1c)を多数一体に形成したことにより、突起物(1c)が裏面(1a)から突出しているため、コンクリート打設時に空気が外部に逃げ易く、打設したコンクリート内に空気溜りができず、しかもコンクリート構造物とプレート本体(1)との固着性が極めて高く、打設コンクリート内の空洞化によるプレート本体(1)の脱落や割れも防止できる。   In the present invention, since a large number of concrete protrusions (1c) are integrally formed on the back surface (1a) of the plate body (1), the protrusions (1c) protrude from the back surface (1a). The air easily escapes to the outside during placement, the air does not accumulate in the placed concrete, and the adherence between the concrete structure and the plate body (1) is extremely high. (1) can be prevented from falling off and cracking.

更に、プレート本体(1)の少なくとも四隅にネジ用取付手段(3)を設けたことにより、プレート本体(1)を枠組する際に、連結金具とネジでもって簡単に連結でき、作業性が極めてよい。   Further, by providing the screw mounting means (3) at least at the four corners of the plate body (1), when the plate body (1) is framed, it can be easily connected with the connecting metal fittings and screws, and the workability is extremely high. Good.

また、プレート本体(1)には、多数の貫通穴(1d)を穿設したことにより、打設コンクリートの充填状態が確認でき、空洞化を防止できると共に、貫通穴(1d)に打設コンクリートが入り込みコンクリート構造物との固着性がより強固となる。更に、貫通穴(1d)が突起物(1c)の中心に穿設すると、貫通穴(1d)によるプレート本体(1)の強度が損なわれることなく穿設できる。   In addition, the plate body (1) has a number of through holes (1d), so that the filling condition of the cast concrete can be confirmed, and the hollow concrete can be prevented, and the cast concrete in the through hole (1d). Enters and becomes more firmly fixed to the concrete structure. Furthermore, when the through hole (1d) is drilled in the center of the projection (1c), the plate body (1) can be drilled without damaging the strength of the plate body (1).

つまり、本発明の残存型枠においては、プレート本体(1)の裏面(1a)から突起物(1c)を突出したことにより、コンクリート打設時に空気溜りがなくコンクリート構造物内の空洞化を防止できる点、プレート本体(1)がコンクリート構造物の表面に強固に固着される点、ネジ用取付手段(3)によるプレート本体(1)の枠組が容易になる点、貫通穴(1d)による打設コンクリートの充填状態の確認と固着性がより高まる点等を同時に満足するものである。   In other words, in the remaining formwork of the present invention, the protrusion (1c) protrudes from the back surface (1a) of the plate body (1), so that there is no air accumulation during concrete placement, and the hollowing of the concrete structure is prevented. Points that can be made, that the plate body (1) is firmly fixed to the surface of the concrete structure, that the frame of the plate body (1) is easy by the screw mounting means (3), and that the through hole (1d) is used It satisfies the confirmation of the filling state of the installed concrete and the point that the adhesiveness is further enhanced.

以下、本発明の実施形態につき、図を基に説明する。図1は本発明の残存型枠を示す断面図、図2は本発明の残存型枠を示す正面図、図3は本発明で他の突起物を形成した状態を示す断面図、図4は貫通穴を突起物の中心に穿設した状態の説明図、図5,図6は本発明で他のネジ用取付手段を設けた状態の要部断面図、図7は本発明のバカ穴のネジ用取付手段を示す要部断面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a cross-sectional view showing the remaining mold of the present invention, FIG. 2 is a front view showing the remaining mold of the present invention, FIG. 3 is a cross-sectional view showing a state in which another protrusion is formed in the present invention, and FIG. FIG. 5 and FIG. 6 are cross-sectional views of the main part in a state in which another screw mounting means is provided in the present invention, and FIG. It is principal part sectional drawing which shows the attachment means for screws.

先ず図1,2において、(1)はコンクリート製のプレート本体である。このプレート本体(1)は一定の厚さと面積でコンクリートを硬化させたプレート状のものであり、前記コンクリートとしては一般のポルトランドセメントに適量の砂等の骨材を混入させ硬化したもの、あるいは単にレジンコンクリートや特殊シリカセメントだけで硬化したもの等を多く使用するが、硬化したコンクリートに低粘度のビニール系モノマーを含浸、重合させたり、コンクリートに金属短繊維を混入し硬化させ、その中に低粘度のビニール系ポリマーを含浸、重合して耐久性及び機械的強度を著しく向上させたものを用いてもよい。又、プレート本体(1)の表面(1b)は見栄えを良くするために、通常は擬石風の化粧仕上を施して形成されるが、本発明ではコンクリート構造物の人目に付かない箇所に使用するものであるから、化粧仕上が必要としない。   1 and 2, (1) is a concrete plate body. This plate body (1) is a plate-like material in which concrete is hardened with a constant thickness and area. As the concrete, it is hardened by mixing an appropriate amount of aggregate such as sand in general Portland cement, or simply Resin concrete or hardened only with special silica cement is often used, but the hardened concrete is impregnated with a low-viscosity vinyl monomer and polymerized, or mixed with short metal fibers and hardened. You may use what impregnated and polymerized the vinyl polymer of a viscosity and improved durability and mechanical strength remarkably. Further, the surface (1b) of the plate body (1) is usually formed by applying a pseudo stone-like decorative finish to improve the appearance, but in the present invention, it is used in a place where a concrete structure is not visible. Because it is a thing, there is no need for a cosmetic finish.

次に、プレート本体(1)の裏面(1a)には、プレート本体(1)と同一なコンクリート製の突起物(1c)を多数一体に形成している。この突起物(1c)の形状としては、図1,2に示す略半球状のもの、あるいは図示しないが円錐台,円柱状のもの、更に図3に示す角錐台のもの、あるいは図示しないが多角錐台等のものであり、これらは後述する貫通穴(1d)を穿設関係上好ましいが、形状は裏面(1a)から突出する形状ならば限定されない。また、突起物(1c)の配列としては、並列、千鳥状等を含む。   Next, a large number of concrete protrusions (1c) identical to the plate body (1) are integrally formed on the back surface (1a) of the plate body (1). As the shape of the projection (1c), the substantially hemispherical shape shown in FIGS. 1 and 2, or a truncated cone or columnar shape, not shown, and a truncated pyramid shape shown in FIG. These are preferably a truncated pyramid, and these are preferable in terms of drilling through holes (1d) described later, but the shape is not limited as long as the shape protrudes from the back surface (1a). Further, the arrangement of the protrusions (1c) includes parallel, staggered, and the like.

このように、プレート本体(1)の裏面(1a)に突起物(1c)を形成しても、その突出して成る突起物(1c)であるため、コンクリート打設時に空気の逃げがよく、コンクリート内部に空気溜りが生じることがなく、本発明の残存型枠を使用することにより、空洞のない強固なコンクリート構造物が完成できる。   In this way, even if the projection (1c) is formed on the back surface (1a) of the plate body (1), the projection (1c) is a projecting projection (1c). The use of the remaining mold of the present invention does not cause air accumulation inside, and a strong concrete structure without a cavity can be completed.

また、プレート本体(1)には、多数の貫通穴(1d)を穿設させている。この貫通穴(1d)は、図1,2に示すように突起物(1c)をよけて穿設させる場合と、あるいは図4のように突起物(1c)の中心に穿設する場合があり、突起物(1c)の中心に穿設させたものは、穿設した箇所が突起物(1c)に補強された状態であるからプレート本体(1)に多数の貫通穴(1d)を穿設させても曲げに強く好ましい。更に、貫通穴(1d)の形状としては、ストレート穴,テーパー穴,段付穴等を含むものである。   The plate body (1) has a number of through holes (1d). The through hole (1d) may be formed by avoiding the protrusion (1c) as shown in FIGS. 1 and 2, or may be formed at the center of the protrusion (1c) as shown in FIG. Yes, the one drilled in the center of the projection (1c) is in a state where the drilled portion is reinforced by the projection (1c), so a large number of through holes (1d) are drilled in the plate body (1). Even if it is provided, it is strong and preferable for bending. Further, the shape of the through hole (1d) includes a straight hole, a tapered hole, a stepped hole, and the like.

(2)はプレート本体(1)の内部に埋設した補強材であり、該補強材(2)はプレート本体(1)を補強するためのものである。この補強材(2)としては、金属製の鉄筋や網状体のものが使用され、特には、表面処理した金網,抜穴金網板が用いられ、特にその中でもエキスパンドメタルが特有な網目形状からして強度的な面、プレート本体(1)との結合性及び安価の面で使用するのが好ましい。又、補強材(2)の表面処理としてはメッキ処理,塗装処理等を施す。この時、ダブルコートカチオン電着塗装を施すと、防錆効果が極めて高く特に好ましいものとなる。尚、このダブルコートカチオン電着塗装とは、従来のカチオン電着塗装を2回行う塗装方法であり、これは従来1回のカチオン電着塗装では塗装される物の塗面の平滑性を求めるとエッジ部の塗装がされず、この耐エッジ部の防食性と塗面平滑性を解消するための塗装方法である。即ち、第1回の電着では耐エッジ防食性だけの機能を持たせ、それによって生じる塗面平滑性の低下は第2回の電着によってカバーしようとするものである。このダブルコートカチオン電着塗装では、補強材(2)がエキスパンドメタルである場合に、そのエッジ部が特に多いため、そのエッジ部の塗装を良く行える極めて有効な防錆効果であり、耐久性を高める。   (2) is a reinforcing material embedded in the plate body (1), and the reinforcing material (2) is for reinforcing the plate body (1). As the reinforcing material (2), a metal reinforcing bar or a net-like material is used, and in particular, a surface-treated wire mesh or a perforated wire mesh plate is used, and in particular, expanded metal has a special mesh shape. It is preferable to use it in terms of strength and strength, connectivity with the plate body (1), and low cost. Further, as the surface treatment of the reinforcing material (2), plating treatment, painting treatment, etc. are performed. At this time, when a double coat cationic electrodeposition coating is applied, the rust prevention effect is extremely high, which is particularly preferable. The double-coat cation electrodeposition coating is a coating method in which the conventional cation electrodeposition coating is performed twice, and this requires the smoothness of the coating surface of the object to be coated in the conventional one cation electrodeposition coating. This is a coating method for eliminating the anti-corrosion property and smoothness of the coated surface of the edge-resistant portion without coating the edge portion. That is, in the first electrodeposition, only the edge anticorrosion resistance is provided, and the resulting decrease in the smoothness of the coating surface is to be covered by the second electrodeposition. In this double coat cationic electrodeposition coating, when the reinforcing material (2) is expanded metal, the edge portion is particularly large. Increase.

(3)はプレート本体(1)の裏面(1a)の少なくとも四隅に設けたネジ用取付手段である。このネジ用取付手段(3)は、プレート本体(1)を枠組する際に、連結するのに使用するネジを取付けるためのものであり、特には、雄ネジを螺合して取付けるインサートナットや取付片を含み、あるいは雄ネジが挿通して取付けられるバカ穴である。   (3) is screw attachment means provided at at least four corners of the back surface (1a) of the plate body (1). The screw attachment means (3) is for attaching a screw used to connect the plate body (1) when the frame is assembled. It is a fool hole that includes a mounting piece or is inserted through a male screw.

以下、このネジ用取付手段(3)の実施形態について説明する。   Hereinafter, an embodiment of the screw attachment means (3) will be described.

先ず、本発明の請求項4では、図1又は2に示すように、ネジ用取付手段(3)が金属製のインサートナット(31)であり、このインサートナット(31)がプレート本体(1)の裏面(1a)の少なくとも四隅に設けたものである。このインサートナット(31)は裏面(1a)と面一に雌ネジ部(31a)を露出して埋設され、その埋設した側の先端は補強材(2)と固着させるのが、抜け防止の面で好ましい。   First, in Claim 4 of this invention, as shown in FIG. 1 or 2, the screw attachment means (3) is a metal insert nut (31), and this insert nut (31) is the plate body (1). Are provided in at least four corners of the back surface (1a). This insert nut (31) is embedded with the female thread (31a) exposed flush with the back surface (1a), and the tip of the embedded side is fixed to the reinforcing material (2) to prevent it from coming off. Is preferable.

次に、本発明の請求項5においては、図5,6に示すように、ネジ用取付手段(3)がタッピンネジ用の取付片(32),(33)とし、図5の取付片(32)は角形の取付片であり、図6の取付片(33)は箱形の取付片である。   Next, in claim 5 of the present invention, as shown in FIGS. 5 and 6, the screw attachment means (3) is the attachment pieces (32), (33) for tapping screws, and the attachment pieces (32 ) Is a square mounting piece, and the mounting piece (33) in FIG. 6 is a box-shaped mounting piece.

前記角形の取付片(32)は、金属製の断面略コの字状で、プレート本体(1)の裏面(1a)に角形締着部(32a)側を突出して装着させている。この角形締着部(32a)にはタッピンネジ用の螺合部(32b)を形成している。また、角形締着部(32a)は金属製の細長板を略コの字状に折曲し、その板中央に形成された角形のもので2本の脚部(32c)で支持されている。しかも、その角形締着部(32a)にはタッピンネジが螺合可能な螺合部(32b)を形成し、取付片(32)の脚部(32c)の他端は直角に短く折曲し補強材(2)と溶着させるのが、抜け防止の面で好ましい。また、この取付片(32)をプレート本体(1)の裏面(1a)から突出させる長さは、螺合部(32b)を貫通するタッピンネジがプレート本体(1)に当らない長さとする。   The square attachment piece (32) has a substantially U-shaped metal cross section, and is attached to the back surface (1a) of the plate body (1) with the square fastening portion (32a) side protruding. A screwing portion (32b) for a tapping screw is formed in the rectangular fastening portion (32a). In addition, the rectangular fastening portion (32a) is formed by bending a metal elongated plate into a substantially U-shape and is formed in the center of the plate and is supported by two legs (32c). . In addition, the square fastening part (32a) is formed with a threaded part (32b) to which a tapping screw can be screwed, and the other end of the leg part (32c) of the mounting piece (32) is bent at a right angle for reinforcement. Welding with the material (2) is preferable in terms of prevention of coming off. Moreover, the length which makes this attachment piece (32) protrude from the back surface (1a) of a plate main body (1) is set to the length which the tapping screw which penetrates a screwing part (32b) does not contact | win a plate main body (1).

そして、この螺合部(32b)は、通常タッピンネジ用の下穴であり、該下穴はタッピンネジが螺合可能な大きさとし、角形締着部(32a)の中央に穿設させ、タッピンネジの使用を可能としている。この下穴を穿設する際には、ツバ出し加工を施すと下穴が板厚よりも長くでき、タッピンネジとの螺合部分も長くなるため好ましく、連結金具を使用してプレート本体(1)を連結する際に、タッピンネジと下穴との螺合が強固なものとなる。   This screwing part (32b) is usually a pilot hole for a tapping screw, the pilot hole is sized so that the tapping screw can be screwed in, and is drilled in the center of the rectangular fastening part (32a). Is possible. When drilling the pilot hole, it is preferable to apply a flange to make the pilot hole longer than the plate thickness, and the threaded part with the tapping screw is also longer. When connecting the two, the screwing of the tapping screw and the pilot hole becomes strong.

次に図6の箱形の取付片(33)について説明すると、金属製で外周を囲った略箱形の取付片(33)であり、該箱形の取付片(33)はプレート本体(1)の裏面(1a)に角形締着部(33a)を面一として埋設し装着させている。しかも、この角形締着部(33a)にはタッピンネジが締着可能なタッピンネジ用の下穴(33b)を穿設させている。また、上記タッピンネジ用の下穴(33b)を穿設させる場合には、ツバ出し加工を施すと下穴(33b)が長くでき、タッピンネジとの螺合部分も長くなるため好ましく、連結金具を使用してプレート本体(1)を連結する際に、タッピンネジと下穴(33b)との螺合が強固なものとなり、プレート本体(1)をコンクリート打設時にも充分耐える強度で枠組することができる。更に、箱形の取付片(33)は、その角形胴部(33c)の断面形状が四角形を主とする多角形であり、その角形胴部(33c)は、少なくとも、タッピンネジの挿入に支障がないように、角形締着部(33a)側から一定の長さで多角形状を有していればよく、特にはプレート本体(1)の裏面(1a)から網状体(2)に届く長さが好ましい。尚、上記箱形の取付片(33)を使用してプレート本体(1)の製造をする際には下穴(33b)を一時的にテープやゴム栓で封鎖することにより、角形胴部(33c)内にあまりコンクリートが入ることなく製造できる。   Next, the box-shaped mounting piece (33) shown in FIG. 6 will be described. The box-shaped mounting piece (33) is a substantially box-shaped mounting piece (33) that is made of metal and surrounds the outer periphery. ) Is embedded with the square fastening part (33a) flush with the back face (1a). In addition, a pilot hole (33b) for a tapping screw to which the tapping screw can be fastened is formed in the rectangular fastening portion (33a). In addition, when drilling the pilot hole (33b) for the tapping screw, it is preferable to apply the flange to make the pilot hole (33b) longer and the threaded part with the tapping screw to be longer. Thus, when the plate body (1) is connected, the screwing between the tapping screw and the pilot hole (33b) becomes strong, and the plate body (1) can be framed with sufficient strength even when the concrete is placed. . Further, the box-shaped mounting piece (33) has a polygonal shape in which the cross section of the rectangular body (33c) is mainly a quadrangle, and the rectangular body (33c) has at least an obstacle to the insertion of the tapping screw. So long as it has a polygonal shape with a certain length from the side of the square fastening part (33a), and in particular, the length reaching the mesh body (2) from the back surface (1a) of the plate body (1) Is preferred. When the plate body (1) is manufactured using the box-shaped mounting piece (33), the rectangular hole (33b) is temporarily sealed with a tape or a rubber stopper so that the rectangular body ( 33c) Can be manufactured without much concrete inside.

尚、上記角形及び箱形の取付片(32),(33)は、外周が四角形のものを説明したが、外周が丸形にしてもよい。また、図示しないが、角形胴部(33c)内に軟質材、例えば発泡ゴム,発泡樹脂等を入れると、打設コンクリートが角形胴部(33c)内に入るのを防止でき、タッピンネジが角形胴部(33c)内に容易に入り込める。   The square and box-shaped mounting pieces (32) and (33) have been described as having a rectangular outer periphery, but the outer periphery may be round. Although not shown, when a soft material such as foamed rubber or foamed resin is placed in the rectangular barrel (33c), it is possible to prevent the cast concrete from entering the rectangular barrel (33c), and the tapping screw is connected to the rectangular barrel. Can easily enter the part (33c).

本発明の請求項6においては、図7に示すように、ネジ用取付手段(3)がバカ穴(34)であり、これはボルトを挿通させるためのものである。このバカ穴(34)は、プレート本体(1)を枠組する際に、コンクリート打設内が狭く、その中に手が入っても作業者が入れず、人が外側から枠組しなければならない場合に、このバカ穴(34)に外側からボルトを挿入して枠組するのに有効となる。尚、このバカ穴(34)は、前記貫通穴(1d)の内で、比較的プレート本体(1)の四隅付近に穿設され、且つ、ボルトが挿通可能なバカ穴程度の大きさのものであれば、それを代用することもできる。   In Claim 6 of this invention, as shown in FIG. 7, the screw attachment means (3) is a fool hole (34), and this is for inserting a bolt. When the plate body (1) is framed, this fool hole (34) is narrow in the concrete placement, and even if a hand enters it, the worker cannot enter it and the person must frame it from the outside. In addition, it is effective to insert a bolt into the fool hole (34) from the outside to form a frame. The fool hole (34) is drilled relatively near the four corners of the plate body (1) in the through hole (1d) and has a size about the fool hole through which the bolt can be inserted. If so, you can substitute it.

また、前記ネジ用取付手段(3)においては、プレート本体(1)の四隅以外にも必要に応じて増加して設けてもよい。   Moreover, in the said screw attachment means (3), you may increase and provide as needed other than the four corners of a plate main body (1).
