The present invention relates to a lifting inversion hole forming tool that forms

【０００２】[0002]

【従来の技術】[Prior art]

従来より、吊り上げて反転させることが可能な吊上反転穴を重心位置に穿設し たコンクリート製品が一般に知られている。 BACKGROUND ART Conventionally, a concrete product in which a lifting inversion hole that can be lifted and inverted is formed at a position of a center of gravity is generally known.

【０００３】 しかして、該コンクリート製品、特にコンクリートＵ字溝の製造は、内型枠と 吊上穴反転形成具を取り付けた外型枠との間にコンクリート１１を打設して製造 されるが、従来この吊上反転穴形成具は一般にパイプ状の吊上反転穴形成基体と この形成基体の略中間に取り付けられた大径円盤状のアンカーとから形成されて いる。[0003] Thus, the production of the concrete product, particularly the concrete U-shaped groove, is carried out by casting concrete 11 between an inner mold and an outer mold to which a lifting hole reversing tool is attached. Conventionally, this lifting inversion hole forming device is generally formed of a pipe-shaped lifting inversion hole forming base and a large-diameter disk-shaped anchor attached substantially at the center of the formation base.

【０００４】 ここで当該吊上反転穴形成具の製造は、まずパイプ状の吊上反転穴形成基体を 所定の長さに切断し、その後あらかじめ大径の円盤状に作成され、表面に複数の 穴が穿設されてあると共に、外周端部が左右互い違いに外周突片を折曲させて形 成したアンカーを吊上反転穴形成基体にはめ込み、吊上反転穴形成基体の中間部 で該アンカーを溶接などして固定して製造するものであった。Here, in the manufacture of the lifting inversion hole forming tool, first, a pipe-shaped lifting inversion hole forming base is cut into a predetermined length, and then a large-diameter disk is formed in advance and a plurality of disks are formed on the surface. A hole is drilled, and an anchor formed by bending the outer circumferential projection at the outer peripheral end alternately to the left and right is fitted into the lifting inverted hole forming base, and the anchor is formed at an intermediate portion of the lifting inverted hole forming base. Was fixed by welding or the like.

【０００５】 しかしながら、この様な従来の吊上反転穴形成具では製造工程と部品使用量が が多いため、製造コストが高価になってしまっていると共に、その運搬作業や収 納にに際しては大径のアンカーがかさばってしまい、運搬効率や収納効率があま り良くないとの課題があった。[0005] However, in such a conventional lifting inverted hole forming tool, the manufacturing process and the amount of components used are large, so that the manufacturing cost is high, and the transportation work and the storage are large. There was a problem that the diameter of the anchor was bulky and transportation and storage efficiency were not sufficiently improved.

【０００６】 本考案はかかる課題を解決するために創案されたものであり、本考案によれば 、製作工程が簡易で部品の大きさが小さくてすむため、製造コストを安価になし 得ると共に簡単に組み立てることが出来、かつ製品のかさばりがないため、その 運搬効率や収納効率がきわめて良好となる。The present invention has been made to solve such a problem. According to the present invention, the manufacturing process is simple and the size of parts is small, so that the manufacturing cost can be reduced and the manufacturing cost can be reduced. Since the product can be assembled without any bulk and the product is not bulky, its transport efficiency and storage efficiency are extremely good.

【０００７】 さらに本考案にかかる吊上反転穴形成具を埋設したコンクリート製Ｕ字溝など のコンクリート製品では、従来と同様に安全かつ、簡易に吊り上げ反転すること ができ、しかも一度埋設した吊上反転穴形成具は強固にコンクリート内で固着し 、簡単に抜出することがない。[0007] Furthermore, concrete products such as a concrete U-shaped groove in which the lifting inversion hole forming tool according to the present invention is embedded can be lifted and inverted safely and easily as in the past, and the lifting once embedded is performed. The inverted hole forming tool is firmly fixed in the concrete and cannot be easily extracted.

【考案の実施の形態】[Embodiment of the invention]

以下本考案を図に示す一実施例に基づいて説明する。 Hereinafter, the present invention will be described based on an embodiment shown in the drawings.

【０００８】 図において、符号１は吊上反転穴形成基体を示す。[0008] In the drawings, reference numeral 1 denotes a lifting inverted hole forming base.

【０００９】 該吊上反転穴形成基体１は両端が開口する略円筒パイプ状をなしており、予め 所定の長さに切断されている。The base 1 has a substantially cylindrical pipe with both ends open, and is cut in advance to a predetermined length.

【００１０】 次に符号２は円盤状のアンカー片を示し、該アンカー片２は鋼製で形成され、 その中心部には前記吊上反転穴形成基体１の外周径とほぼ同等の径を有する透孔 ３が設けられている。[0010] Next, reference numeral 2 denotes a disk-shaped anchor piece, which is made of steel, and has a diameter substantially equal to the outer diameter of the base body 1 having the lifting inverted hole formed at the center thereof. A through hole 3 is provided.

【００１１】 そして、図１から理解されるように、この透孔３の端部からは略鋸刃状に間隔 が設けられ、かつ中心部に向かって内向き放射状に突設する複数の係止片４が設 けられている。As can be understood from FIG. 1, a plurality of locking members are provided at intervals from the end of the through hole 3 in a substantially saw-tooth shape, and project radially inward toward the center. Piece 4 is provided.

【００１２】 しかして２枚のアンカー片２，２を前記吊上反転穴形成基体１の長手方向両端 側から吊上反転穴形成基体１の長手方向中間位置に向かって被嵌させる（図１参 照）。Then, the two anchor pieces 2 are fitted from both ends in the longitudinal direction of the lifting inverted hole forming base 1 toward the intermediate position in the longitudinal direction of the lifting inverted hole forming base 1 (see FIG. 1). See).

【００１３】 すると、図２に示すように吊上反転穴形成基体１の長手方向中間位置では２枚 のアンカー片２，２が重ね合わされる。Then, as shown in FIG. 2, at the intermediate position in the longitudinal direction of the lifting inverted hole forming base 1, the two anchor pieces 2 are overlapped.

【００１４】 このとき、双方のアンカー片２における複数の係止片４は図２に示すように、 アンカー片２の先端側に向かって急勾配の下り傾斜を有して挿入端部側に向かい 弓なりに傾いて設置される。At this time, as shown in FIG. 2, the plurality of locking pieces 4 of both anchor pieces 2 have a steep downward slope toward the distal end side of the anchor piece 2 and face the insertion end side. It is installed with a bow.

【００１５】 そして、相互のアンカー片２に設けられた複数の係止片４は、その弾発力によ って前記吊上反転穴形成基体１の外周面を押圧して強固に係止するものとなる。 従って、いったん吊上反転穴形成基体の長手方向中間位置で重ね合わされた２枚 のアンカー片２，２はその位置から移動してずれることが全くない。The plurality of locking pieces 4 provided on the mutual anchor pieces 2 press the outer peripheral surface of the lifting inverted hole forming base 1 by its resilient force to be locked firmly. It will be. Therefore, the two anchor pieces 2, 2 once superposed at the intermediate position in the longitudinal direction of the lifting inverted hole forming base do not move at all from the position.

【００１６】 さらに、両アンカー片２，２の係止片４間には略山状の空間５が形成される。A substantially mountain-shaped space 5 is formed between the locking pieces 4 of the anchor pieces 2 and 2.

【００１７】 また、両アンカー片２，２の係止片４は図３から理解されるように、相互に重 ならないようにずらして配置される。その配置状態を図４及び図５に示す。As can be seen from FIG. 3, the locking pieces 4 of the anchor pieces 2 and 2 are arranged so as not to overlap with each other. The arrangement is shown in FIGS.

【００１８】 後述するが、このような両アンカー片２における係止片４の配置をすることに より打設するコンクリート１１との付着が著しく向上する。As will be described later, by arranging the locking pieces 4 on both the anchor pieces 2, the adhesion to the concrete 11 to be poured is remarkably improved.

【００１９】 次に、このように形成された吊上反転穴形成具６を型枠内に設置し、埋設する 状態につき説明する。Next, a state in which the lifting inverted hole forming tool 6 formed as described above is installed in a mold and buried will be described.

【００２０】 図４に示すように、外型枠７には吊上反転穴形成具６を保持するための支持具 ８が型枠内に突設して設けられており、この支持具８に吊上反転穴形成具６の一 方側開口がはまり込んで保持され、型枠内に設置される。As shown in FIG. 4, a support 8 for holding the lifting reversing hole forming tool 6 is provided on the outer mold frame 7 so as to protrude into the mold. The opening on one side of the lifting inversion hole forming tool 6 is fitted and held, and is installed in the formwork.

【００２１】 ところでこの吊上反転穴形成具６の長手方向他端側の開口には樹脂材から形成 されたキャップ９が被せられ、コンクリートの侵入が防止されている。Incidentally, a cap 9 formed of a resin material is placed over the opening at the other end in the longitudinal direction of the lifting inverted hole forming tool 6 to prevent concrete from entering.

【００２２】 以上において、型枠内にコンクリートが打設され、そのコンクリートが固化す ると、吊上反転穴形成具６は一方側の開口をコンクリート側壁に露出する形で埋 設される。その状態を図５に示す。図５では外型枠７を脱型した状態が示されて いる。In the above, when concrete is poured into the formwork and the concrete is solidified, the lifting inversion hole forming tool 6 is buried in such a manner that one opening is exposed on the side wall of the concrete. The state is shown in FIG. FIG. 5 shows a state in which the outer mold frame 7 has been removed.

【００２３】 この際、アンカー片２，２には係止片４と係止片４との間、あるいは係止片４ と係止片４とで形成された空間５にコンクリートが行き渡り、コンクリート１１ が固化したときに強力な付着力が発揮される。At this time, the concrete spreads over the anchor pieces 2 and 2 between the locking pieces 4 and the space 5 formed by the locking pieces 4 and the locking pieces 4, and the concrete 11 Strong adhesion is exerted when is solidified.

【００２４】 よって、アンカー片４自体の径が小さく、外側への張り出しが小さいものであ っても充分なアンカー効果を発揮することとなる。Therefore, even if the diameter of the anchor piece 4 itself is small and the outward protrusion is small, a sufficient anchor effect can be exhibited.

【考案の効果】[Effect of the invention]

以上説明したように本考案によれば、製作工程が簡易で部品の大きさが小さく てすむため、製造コストを安価になし得ると共に簡単に組み立てることが出来、 かつ製品のかさばりがないため、その運搬効率や収納効率がきわめて良好となる 。 As described above, according to the present invention, since the manufacturing process is simple and the size of the parts is small, the manufacturing cost can be reduced and the assembly can be easily performed, and the product is not bulky. Transport efficiency and storage efficiency are extremely good.

【００２５】 さらに本考案にかかる吊上反転穴形成具を埋設したコンクリート製Ｕ字溝など のコンクリート製品では、従来と同様に安全かつ、簡易に吊り上げ反転すること ができ、しかも一度埋設した吊上反転穴形成具は強固にコンクリート内で固着し 、全く抜出することがない、等優れた効果を奏する。Further, in the concrete product such as a concrete U-shaped groove in which the lifting reversing hole forming tool according to the present invention is embedded, it is possible to safely and easily lift and invert the same as in the past, and furthermore, once the lifting is performed, The inverted hole forming tool has excellent effects such as being firmly fixed in concrete and not being pulled out at all.
