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. About.

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表面に固着し残存して型枠を取り外すことのないコンクリート製の残存型枠が知られている。この残存型枠を枠組する際に、並べて段積した残存型枠は上下及び左右の接続を連結金具で固定しながら行っていた。   Conventionally, when constructing a concrete structure, it is framed as a formwork for placing concrete in the structure, and the cast concrete is fixed to the concrete surface after solidification and remains without removing the formwork. The remaining formwork is known. When the remaining molds were framed, the remaining molds that were stacked side by side were connected while fixing the upper and lower and left and right connections with connecting fittings.

そして、この残存型枠としては、コンクリート製のプレート本体と、その内部に埋設した補強用の網状体と、該網状体に固着しプレートの裏面から断面L字状の一部を露出する溝形鋼から成り、この溝形鋼は四角状に枠組させたものである。   And as this residual formwork, a concrete plate body, a reinforcing mesh embedded in the plate, and a groove shape that is fixed to the mesh and exposes a part of the L-shaped section from the back of the plate It consists of steel, and this channel steel is framed in a square shape.

この残存型枠を枠組する際に、簡単に連結金具でもって強固に連結可能とする残存型枠については本発明者が特開2003−96799号で提案したところである。この特開2003−96799号における残存型枠の構成は、露出する部分の形鋼がプレート本体の裏面と平行な平板部を有し、該平板部に多数のネジ用穴を穿設したものである。そして、このネジ用穴を利用し、段積した残存型枠を連結プレートで連結し確実な枠組を可能とするものであった。   The present inventor has proposed in Japanese Patent Application Laid-Open No. 2003-96799 regarding a residual mold that can be easily and firmly connected with a connecting bracket when the residual mold is framed. The structure of the remaining mold in Japanese Patent Laid-Open No. 2003-96799 is such that the exposed portion of the shape steel has a flat plate portion parallel to the back surface of the plate body, and a number of screw holes are formed in the flat plate portion. is there. Then, by using this screw hole, the stacked residual molds are connected by a connecting plate to enable a reliable frame.

また他の残存型枠としては、本発明者の提案した特開平10−292399号及び特開平10−306461号がある。これはコンクリート製のプレート本体と、その内部に埋設した補強用の網状体とから成り、且つ、プレート本体に多数の貫通穴や溝穴を穿設したものもある。この手の残存型枠を枠組するには、貫通穴を穿設したものはその貫通穴を利用し、溝穴の場合はその溝穴を貫通させて貫通穴にし、それぞれの貫通穴を利用して連結プレートとネジで段積した残存型枠を連結固定させていた。

As other remaining molds, there are JP-A-10-292399 and JP-A-10-306461 proposed by the present inventor. This is made up of a concrete plate body and a reinforcing mesh body embedded in the plate body, and there are also some in which a large number of through holes and groove holes are formed in the plate body. In order to frame this type of remaining formwork, those with through holes are used, and in the case of slots, the slots are penetrated into through holes, and the respective through holes are used. The remaining molds stacked in stages with the connecting plate and screws were connected and fixed.
JP 2003-96799 A JP-A-10-292399 Japanese Patent Laid-Open No. 10-306461

しかしながら、前記特開2003−96799号の残存型枠においては、プレート本体の裏面から露出する形鋼の断面形状がL字状であり、その露出した平板部にネジ用穴を穿設させている。しかも、この平板部はプレート本体の裏面と平行で、その幅に対し片側の側面部のみで支持された片持状態のものである。従って、このような片側支持の平板部にネジ用穴を穿設した場合には、このネジ用穴を利用してプレート本体の枠組を行った後に、生コンクリートを打設すると、打設コンクリートの側圧が枠組したプレート本体に加わり、その側圧が支持棒,連結金具及びネジ用穴に螺合させたネジ等を介して平板部に作用する。すると、片持状態の平板部は側圧によりめくられて変形を起こし、枠組したプレート本体の全体がゆがんで波を打つ状態となる。その結果、打設コンクリートが流出したり、コンクリート固化後の構造物の表面がゆがんだりし見栄えの悪いものとなる等の問題点を有していた。また上記の問題点を解消するのに使用する形鋼の厚さを増加させればよいが、この場合には、残存型枠全体の重量が増加し、運搬や枠組作業に支障をきたし、製造コスト的にも不利となる等の問題点が残る。また、形鋼が四角状に枠組されているため、打設コンクリートが四角状に囲まれた形鋼の枠内に完全に充填されず、これによりコンクリート構造物内に空洞が生じ、コンクリート構造物に弱い部分が存在すると共に、施工現場で枠組する際に構造物の形状に合せてプレート本体を切断する場合にも、形鋼が四角状に枠組されているため、形鋼をも切断しなければならず、プレート本体の切断に時間を要する等の問題点を有していた。   However, in the remaining form of JP-A-2003-96799, the cross-sectional shape of the shape steel exposed from the back surface of the plate body is L-shaped, and a screw hole is formed in the exposed flat plate portion. . In addition, the flat plate portion is parallel to the back surface of the plate main body and is in a cantilever state supported by only one side surface portion with respect to its width. Therefore, when a screw hole is drilled in such a flat plate portion of one side support, after placing the frame of the plate body using this screw hole and placing the ready-mixed concrete, A lateral pressure is applied to the framed plate body, and the lateral pressure acts on the flat plate portion via a support rod, a coupling fitting, a screw screwed into a screw hole, and the like. Then, the flat plate portion in the cantilever state is turned and deformed by the side pressure, and the entire plate body that is framed is distorted and waved. As a result, there have been problems such as casting concrete flowing out, and the surface of the structure after the solidification of the concrete is distorted, resulting in a poor appearance. In addition, it is sufficient to increase the thickness of the shape steel used to solve the above problems, but in this case, the weight of the entire remaining formwork increases, which hinders transportation and frame work, and manufacture. Problems such as cost disadvantages remain. In addition, because the shape steel is framed in a square shape, the cast concrete is not completely filled in the frame of the shape steel surrounded by the square shape, thereby creating a cavity in the concrete structure, and the concrete structure When the plate body is cut according to the shape of the structure when it is framed at the construction site, the shape steel is framed in a square shape, so the shape steel must also be cut. In other words, there was a problem that it took time to cut the plate body.

また、前記特開平10−292399号,特開平10−306461号等の残存型枠においては、貫通穴を利用して残存型枠を枠組するため、その貫通穴に挿通したボルトの頭が枠組して残存型枠の表面に露出し、見栄えが悪く、しかもボルトとナットによる連結固定であるから枠組に手間が掛かる等の問題点を有していた。   Further, in the remaining molds such as JP-A-10-292399 and JP-A-10-306461, the remaining molds are framed using the through holes, so that the heads of the bolts inserted through the through holes are framed. In other words, it is exposed on the surface of the remaining mold, has a poor appearance, and has a problem that the frame is troublesome because it is connected and fixed by bolts and nuts.

本発明は、上記の問題点に鑑みこれを解消するものであり、つまり、残存型枠を枠組する際に、タッピンネジが使用でき、ネジの締付けが極めて容易で取付けたネジがプレート本体の表面から露出することがなく、且つ施工現場でのプレート本体の切断が簡単な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 problems. That is, when the remaining mold is framed, a tapping screw can be used, and the screw can be tightened very easily from the surface of the plate body. An object of the present invention is to provide a residual mold that is not exposed and that can be easily cut at the construction site.

本発明は、プレート本体(1)の裏面(1a)の少なくとも四隅に、裏面(1a)と面一にタッピンネジ用の締着手段(3)を装着させたことにより、締着手段(3)がプレート本体(1)の裏面(1a)と面一であるから、本発明の残存型枠を工場で製造する際に、製造型枠に投入された生コンクリート、特にはノンスランプ状態の生コンクリートの余剰分を一度に掻き落すのに、製造型枠内にある締着手段に邪魔されず、掻き落すことができ、大量生産を可能とし、且つ製品として保管や輸送する際にも、締着手段(3)がプレート本体(1)から突出していないため、直接当って損傷する危険性が少ない。また、締着手段(3)がタッピンネジ用であるから、本発明の残存型枠を枠組する際にタッピンネジが使用できる。このことはネジの螺合作業が極めて簡単で素早くでき、多数枚の残存型枠を枠組するのに作業性を高める。また枠組の際にプレート本体(1)の表面にネジが露出せず見栄えもよい。以上本発明は裏面(1a)と面一にした締着手段(3)でありながらタッピンネジによる締結を可能とし、前記効果を同時に有することである。   According to the present invention, the fastening means (3) is provided by attaching the fastening means (3) for the tapping screw at least at the four corners of the back face (1a) of the plate body (1). Since it is flush with the back surface (1a) of the plate body (1), when the remaining formwork of the present invention is produced in the factory, the ready-mixed concrete put into the production formwork, especially the ready-made concrete in the non-slump state To scrape off the surplus at once, it can be scraped off without being disturbed by the fastening means in the production form, enables mass production, and is also used when storing and transporting as a product. Since (3) does not protrude from the plate body (1), there is little risk of direct hitting and damage. Further, since the fastening means (3) is for the tapping screw, the tapping screw can be used when the remaining mold of the present invention is framed. This makes screwing operation of screws extremely easy and quick, and improves workability for framing a large number of remaining molds. Moreover, the screw is not exposed on the surface of the plate main body (1) during the frame assembly, and it looks good. As described above, the present invention is capable of fastening with a tapping screw while having the fastening means (3) flush with the back surface (1a), and has the above-mentioned effects at the same time.

本発明の請求項2では、箱形取付片(31)にしたことにより、角形締着部(31a)の下方の角形胴部(31c)を横全周に渡って囲うことができ、本発明の残存型枠を製造する際に角形締着部(31a)の下方内に生コンクリートが入らず空間を確保できるため、タッピンネジが角形締着部(31a)を貫通してもプレート本体(1)に当らずに確実に締付けることができる。   According to the second aspect of the present invention, since the box-shaped mounting piece (31) is used, the rectangular body portion (31c) below the rectangular fastening portion (31a) can be surrounded over the entire circumference. When the remaining formwork is manufactured, there is no ready concrete inside the square fastening part (31a) so that a space can be secured. Therefore, even if the tapping screw penetrates the square fastening part (31a), the plate body (1) It can be securely tightened without hitting.

本発明の請求項3では、角形締着部(31a)側の角形胴部(31c)を全体的に囲って空洞部(31d)を確保させているため、本発明の残存型枠を製造する際に生コンクリートが角形締着部(31a)直下の角形胴部(31c)内に入らずに成形でき、タッピンネジが角形締着部(31a)を貫通するのに支障が生じない。   According to the third aspect of the present invention, since the hollow body (31d) is secured by totally surrounding the rectangular body (31c) on the square fastening part (31a) side, the remaining mold of the present invention is manufactured. In this case, the ready-mixed concrete can be formed without entering the square body (31c) just below the square fastening part (31a), and the tapping screw does not interfere with the penetration of the square fastening part (31a).

また、本発明の請求項4では、角形締着部(31a)側の角形胴部(31c)内に軟性材(31f)を内装したことにより、本発明の残存型枠を製造する際に、角形胴部(31c)内に生コンクリートが入るのを完全に防止でき、且つ、角形締着部(31a)を貫通したタッピンネジが容易に抵抗なく軟性材(31f)中に進入でき、タッピンネジの締付けが確実に行える。   In addition, in claim 4 of the present invention, when the remaining mold of the present invention is manufactured by incorporating the soft material (31f) in the square body (31c) on the square fastening portion (31a) side, It can completely prevent the ready-mixed concrete from entering the square body (31c), and the tapping screw that penetrates the square fastening part (31a) can easily enter the soft material (31f) without resistance. Can be done reliably.

また、本発明の請求項5では、円筒取付片(32)にしたことにより、円形締着部(32a)の下方の円形胴部(32c)にプレート本体(1)のコンクリート部分が入り込まず、従って、タッピンネジを円形締着部(32a)の下穴にネジ込んで下方に貫通してもプレート本体(1)に当らず、タッピンネジの締付けが可能となる。   Further, in claim 5 of the present invention, since the cylindrical mounting piece (32) is used, the concrete portion of the plate body (1) does not enter the circular body portion (32c) below the circular fastening portion (32a), Therefore, even if the tapping screw is screwed into the prepared hole of the circular fastening portion (32a) and penetrates downward, the tapping screw can be tightened without hitting the plate body (1).

また、本発明の請求項6では、円形胴部(32c)内を閉鎖した空洞部(32d)を設けたことにより、より確実に円形締着部(32a)下方の円形胴部(32c)内に空間を確保でき、製造時にプレート本体(1)のコンクリートが円形締着部(32a)側の円形胴部(32c)内に入るのを防止できると共にタッピンネジの締付けも可能となる。   Further, in claim 6 of the present invention, by providing the hollow portion (32d) in which the inside of the circular body portion (32c) is closed, the inside of the circular body portion (32c) below the circular fastening portion (32a) is more reliably provided. Space can be secured, and the concrete of the plate main body (1) can be prevented from entering the circular body portion (32c) on the circular fastening portion (32a) side during manufacture, and the tapping screw can be tightened.

また、本発明の請求項7では、前記した請求項4と同様な効果を有する。   The seventh aspect of the present invention has the same effect as the fourth aspect.

また、本発明の請求項8では、締着手段(3)が、断面略コの字状のコ字状取付片(33)で、ツバ出し下穴(33b)に軟性材(33d)を装着させたことにより、コ字状取付片(33)であってもツバ出し下穴(33b)の下部には、プレート本体(1)の成形時に軟性材(33d)によって生コンクリートが充填されず、従ってタッピンネジがツバ出し下穴(33b)と螺合して貫通しても、その先が軟性材(33d)であるから、タッピンネジの締付けが可能となる。   Further, in claim 8 of the present invention, the fastening means (3) is a U-shaped mounting piece (33) having a substantially U-shaped cross section, and the soft material (33d) is attached to the flange hole (33b). As a result, even if it is a U-shaped mounting piece (33), the lower part of the flanged pilot hole (33b) is not filled with ready-mixed concrete by the soft material (33d) when the plate body (1) is molded, Therefore, even if the tapping screw is screwed into and penetrates the collar hole (33b), the tip of the tapping screw is the soft material (33d), so that the tapping screw can be tightened.

FIG. 1 is a cross-sectional view showing a residual mold according to the present invention, FIG. 2 is a plan view of the present invention, FIGS. 3, 4 and 5 are cross-sectional views of main parts with the box-shaped mounting piece of the present invention attached, FIG. 7 is a cross-sectional view of the main part with the cylindrical mounting piece of the present invention attached, FIG. 8 is a cross-sectional view of the main part with the U-shaped mounting piece of the present invention attached, and FIG. FIG. 10 is an overall perspective view of the cylindrical mounting piece of the present invention, and FIG. 11 is an overall perspective view of the U-shaped mounting piece of the present invention.

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. Further, the surface of the plate body (1) is usually formed by applying a fake stone-like cosmetic finish in order to improve the appearance. However, depending on the place of use, the cosmetic finish is not required, so the cosmetic finish may not be provided.

又、上記プレート本体(1)は、その裏面(1a)が平坦あるいは凹凸状のもの、多数の溝穴を穿設させたもの、更にプレート本体(1)に多数貫通穴を穿設したもの等を含む。   The plate body (1) has a flat or uneven back surface (1a), a plurality of slots, and a plate body (1) with a number of through holes. including.

(2)はプレート本体(1)の内部に全部が埋設された網状体であり、該網状体(2)はプレート本体(1)を補強するためのものである。また前記網状体(2)には表面処理した金網,抜穴金網板が用いられ、特に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、網状体(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、網状体(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 net-like body entirely embedded in the plate body (1), and the net-like body (2) is for reinforcing the plate body (1). The mesh body (2) is made of a surface-treated wire mesh or a perforated wire mesh plate. Particularly, the expanded metal has a special mesh shape and is strong in terms of strength, connectivity with the plate body (1) and inexpensive. It is preferable to use it on the surface. Further, as the surface treatment of the mesh body (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 mesh (2) is an 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、裏面(1a)と面一に装着したタッピンネジ用の締着手段である。この締着手段(3)は、タッピンネジを螺合状態で締着させるものであり、又、締着手段(3)が必要に応じて四隅以外に複数追加して設けてもよく、更に締着手段(3)はプレート本体(1)内の網状体(2)と一端を溶着させるのが好ましい。以下この締着手段(3)について請求項2〜8の実施形態を説明する。   (3) is fastening means for a tapping screw that is mounted flush with the back surface (1a) at at least four corners of the back surface (1a) of the plate body (1).
