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、裏面に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 protrusion 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と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 construction cost of a concrete structure increases when used with such a high cost residual mold.

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、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 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ず、強度的にも強く、しかも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突起物を有する残存型枠を提供することを目的とする。   The present invention solves this problem in view of the above-mentioned problems. That is, there is no air accumulation when placing concrete, it is strong in strength, and has high adhesion to the placed concrete, and is low in cost. An object of the present invention is to provide a residual mold having a protrusion that can be manufactured by the above method.

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。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). In addition, screw attachment means (3) are provided at at least four corners of the back surface (1a).

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もの、あるいは、雄ネジ類が挿通可能なバカ穴をいう。   The screw attachment means (3) in the claims of the present invention refers to a screw hole through which a screw including a bolt, a tapping screw or the like is screwed, or a fool hole through which a male screw can be inserted.

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、プレート本体(1)の突起物(1c)を除く厚さを、一定の均一な巾で確保される。従って、従来の貫通穴や溝穴を穿設したものに比べ、その厚さが多少薄くても型枠としての強度を充分に確保でき、且つ、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、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)の脱落や割れが防止できる。   In the present invention, a large number of concrete protrusions (1c) are integrally formed on the back surface (1a) of the plate body (1), so that the thickness excluding the protrusions (1c) of the plate body (1) Secured with a uniform and uniform width. Therefore, the strength as a mold can be sufficiently secured even when the thickness is somewhat thinner than that of a conventional through hole or slot, and the protrusion (1c) protrudes from the back surface (1a). Therefore, air can easily escape to the outside when placing concrete, air cannot be trapped in the placed concrete, and the adherence between the concrete structure and the plate body (1) is extremely high. Dropping and cracking of the plate body (1) due to the conversion can be prevented.

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.

つまり、本発明の残存型枠においては、従来の貫通穴や溝穴を穿設したものに比べ、厚さが多少薄くてもコンクリート打設時の側圧に充分に耐える強度を有する点、コンクリート打設時に空気溜りが発生せず、空洞のないコンクリート構造物を施工できる点、ネジ用取付手段(3)でもって枠組が極めて簡単となる点、突起物(1c)による打設コンクリートとの固着性が高い点等を同時に満足するものである。   In other words, the remaining form of the present invention has a strength sufficient to withstand the lateral pressure during the concrete placement even if the thickness is somewhat thinner than that in which the conventional through holes and slots are formed. It is possible to construct a concrete structure that does not generate air pockets and has no cavities at the time of installation, the screw mounting means (3) makes the frame extremely simple, and the adhesion to the cast concrete with protrusions (1c) It satisfies the high point etc. at the same time.

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,図5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6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, FIG. FIG. 5 is a cross-sectional view of a main part in a state where another screw mounting means is provided in the present invention, and FIG.

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、使用場所によっては化粧仕上が必要ないので化粧仕上をしないこともある。   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. In addition, the surface (1b) of the plate body (1) is usually formed with a fake stone-like cosmetic finish to improve the appearance, but depending on the place of use, the cosmetic finish is not required. There is also.

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の何れかを含み、これらは頂部が丸みや平であるので衝撃に強く損傷し難く好ましいが、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. It includes any one of a truncated pyramid and the like, and since the top part is round or flat, it is preferable to be strong against impact and difficult to damage, but the shape is not limited as long as it 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)から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、打設コンクリートとの固着性が高く、空洞のない強固なコンクリート構造物が完成できる。   Thus, since it is a protrusion (1c) which protrudes from the back surface (1a) of a plate main body (1), air escape is good at the time of concrete placement, and an air pocket does not arise in concrete inside, and this invention By using the remaining formwork, it is possible to complete a strong concrete structure having a high adherability to the cast concrete and having no cavity.

(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タッピンネジ用の取付片等のもの、あるいは雄ネジが挿通して取付けられるバカ穴等である。   (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. A tapping screw mounting piece or the like, or a fool hole or the like through which a male screw is inserted.

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3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 3 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4においては、図4,5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4の取付片(32)は角形の取付片であり、図5の取付片(33)は箱形の取付片である。   Next, in claim 4 of the present invention, as shown in FIGS. 4 and 5, 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. 5 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)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 and is reinforced. Welding with (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5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、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。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。   Next, the box-shaped mounting piece (33) shown in FIG. 5 will be described. The box-shaped mounting piece (33) is a substantially box-shaped mounting piece (33) made of metal and surrounding 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) is a polygon whose cross-sectional shape of the rectangular body (33c) is mainly a quadrangle, and the rectangular body (33c) is at least a rectangular fastening portion (33a). It is only necessary to have a polygonal shape with a certain length from the side, and in particular, a length that reaches the reticulate body (2) from the back surface (1a) of the plate body (1) is preferable. When the plate body (1) is manufactured using the box-shaped mounting piece (33), the rectangular body is formed by temporarily sealing the pilot hole (33b) with tape or a rubber stopper. (33c) Can be manufactured without too much concrete. 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).

尚、上記角形や箱形の取付片(32),(33)は、外周が角形のものを説明したが、外周が丸形にしてもよい。   The square and box-shaped mounting pieces (32) and (33) have been described as having a square outer periphery, but the outer periphery may be round.

本発明の請求項5においては、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。更に、プレート本体(1)に他の金属部材が装着していないので、製造時の成形が簡単で安価にできる利点を有する。   According to the fifth aspect of the present invention, the screw attachment means (3) is a fool hole (34) 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.
