Description

本考案は、セパレータのストッパに係止して対向させた型枠を所定間隔に保持する型枠固定用コーンに関する。   The present invention relates to a mold fixing cone that holds a mold frame locked and opposed to a stopper of a separator at a predetermined interval.

従来、セパレータの両端部にカップを備えたカップセパレータが知られている（例えば非特許文献１参照）。このカップは金属製で型枠と接する端面の面積が小さいから、締め付ける際に型枠の表面を傷付けやすく、組み立て精度に支障をきたす問題があった。また、カップは外径に対して長さが短いから、カップ脱離後の凹所が浅くなって充填したモルタルとコンクリートの付着強度が弱くなり、モルタルが硬化前に自重で剥離しやすいという問題もあった。   Conventionally, a cup separator provided with cups at both ends of the separator is known (for example, see Non-Patent Document 1). Since this cup is made of metal and has a small area of the end surface in contact with the mold, there is a problem that the surface of the mold is easily damaged when tightening, and the assembly accuracy is hindered. In addition, since the cup is short with respect to the outer diameter, the recess after the cup is detached becomes shallow and the adhesion strength between the filled mortar and concrete is weakened, and the mortar is easily peeled off by its own weight before curing. There was also.

一方、セパレータのネジ部と螺合するプラスチック製のポリコーンも公知である（例えば非特許文献２参照）。このポリコーンは型枠と接する端面の面積が大きく、ポリコーンの長さも前記カップと比較して長い。しかし、ポリコーンはセパレータと螺合する構造であるから、取り付け及び取り外しが面倒で作業性に劣る問題があった。また、ネジ部が傷付くと使用不能となり再使用できる回数が少ないという問題もあった。

This polycone has a large end face area in contact with the mold, and the length of the polycone is longer than that of the cup. However, since the polycone has a structure that is screwed with the separator, there is a problem that attachment and removal are troublesome and workability is poor. In addition, when the screw portion is damaged, there is a problem in that it cannot be used and the number of times it can be reused is small.

本考案のコーンの材質としては、ＡＢＳ樹脂、ナイロン樹脂、ポリプロピレン樹脂、ポリエチレン樹脂等のプラスチックが用いられる。以下、本考案の実施例を図面に基づいて具体的に説明する。   As the material of the cone of the present invention, plastics such as ABS resin, nylon resin, polypropylene resin, and polyethylene resin are used. Embodiments of the present invention will be specifically described below with reference to the drawings.

図１は実施例のコーンの一部切り欠き斜視図、図２は実施例のコーンの使用状態とモルタルの充填を示す説明図である。図中、１はコーン、１ａは挿通孔、１ｂは係止部、１ｃは当接部、１ｄは延設部、１ｅは凹所、２はセパレータ、２ａはネジ部、２ｂはストッパ、２ｃは折り取り溝、３は型枠、４は締結具、Ｃはコンクリート、Ｈは凹所、Ｍはモルタルである。   FIG. 1 is a partially cutaway perspective view of a cone according to the embodiment, and FIG. In the figure, 1 is a cone, 1a is an insertion hole, 1b is a locking portion, 1c is a contact portion, 1d is an extending portion, 1e is a recess, 2 is a separator, 2a is a screw portion, 2b is a stopper, 2c is Folding grooves, 3 is a mold, 4 is a fastener, C is concrete, H is a recess, and M is mortar.

本実施例のコーン１は、図１に示すように大径側の外径が３３ｍｍ、小径側の外径が２２ｍｍ、長さが２５ｍｍの円錐台形状のプラスチック製で、セパレータ２を通す挿通孔１ａはネジ無しの孔に形成している。型枠３側の端面は型枠３と接する当接部１ｃとし、４ｍｍ厚に形成している。また、型枠３側の端面にはコーン１の取外し具の先端が挿入できる環状の凹所１ｅを形成し、取り外しを容易にしている。   As shown in FIG. 1, the cone 1 of this embodiment is made of a truncated cone-shaped plastic having a large-diameter outer diameter of 33 mm, a small-diameter outer diameter of 22 mm, and a length of 25 mm. 1a is formed in a hole without a screw. The end surface on the mold 3 side is a contact portion 1c that comes into contact with the mold 3 and has a thickness of 4 mm. In addition, an annular recess 1e into which the tip of the removal tool of the cone 1 can be inserted is formed on the end surface on the mold 3 side to facilitate removal.

コンクリートＣ側端面のストッパ２ｂの外径より拡径する部分はコンクリートＣ方向へ筒状に延設して延設部１ｄを形成し、同延設部１ｄの外周面とコーン１の外周面を連続した勾配に形成している。ストッパ２ｂと係止する係止部１ｂは延設部１ｄの端面から１２ｍｍの奥深い位置に形成している。   The portion of the concrete C side end surface that is larger than the outer diameter of the stopper 2b extends in a cylindrical shape in the direction of the concrete C to form an extended portion 1d, and the outer peripheral surface of the extended portion 1d and the outer peripheral surface of the cone 1 are A continuous gradient is formed. The locking portion 1b that locks with the stopper 2b is formed at a depth of 12 mm from the end surface of the extending portion 1d.

図２（ａ）にコンクリートＣの打設直前のコーン１の使用状態を示す。コーン１の当接部１ｃは型枠３との接地面積が大きいから、締結具４で締め付ける際にコーン１が型枠３の表面を傷付けることがなく、電動で締め付けても型枠３の組み立て精度に支障をきたすことがない。挿通孔１ａはネジが切られていないから、取り付け及び取り外しも迅速に行えて作業性に優れ、何度も再使用できる。   FIG. 2A shows a use state of the cone 1 immediately before the concrete C is placed. Since the contact area 1c of the cone 1 has a large contact area with the mold 3, the cone 1 does not damage the surface of the mold 3 when tightened with the fastener 4, and the assembly of the mold 3 can be performed even if it is tightened electrically. There is no hindrance to accuracy. Since the insertion hole 1a is not threaded, it can be quickly attached and removed, has excellent workability, and can be reused many times.

また、コーン１の長さは延設部１ｄで従来のカップより長くなるから、図２（ｂ）に示すようにコーン１の脱離後の凹所Ｈが深く形成され、充填したモルタルＭとコンクリートＣの付着強度が向上してモルタルＭが剥離し難い。Ｌは本実施例による深さ、Ｌ０は従来技術による深さを示す。 Further, since the length of the cone 1 is longer than that of the conventional cup at the extending portion 1d, the recess H after the detachment of the cone 1 is formed deeply as shown in FIG. The adhesion strength of the concrete C is improved and the mortar M is hardly peeled off. L is the depth according to this embodiment, and L 0 is the depth according to the prior art.

図３に示すのは、挿通孔の型枠側を貫通可能な薄膜で閉塞した実施例の型枠固定用コーンの他の例である。図３は実施例の他の例のコーンの一部切り欠き斜視図である。図中、１ｆは薄膜である。コーン１の挿通孔１ａの型枠側には薄膜１ｆをコーン１と一体的に成形し、使用前まで挿通孔１ａを閉塞する。使用時はセパレータ２の端部で薄膜１ｆを突破して挿通することで、薄膜１ｆの破れ跡による摩擦で型枠３の組み立て中におけるセパレータ２からのコーン１の脱落が防止されて作業性が向上する。その他、符号、構成、作用効果は実施例と同じである。   FIG. 3 shows another example of the mold fixing cone of the embodiment in which the mold hole side of the insertion hole is closed with a thin film that can penetrate. FIG. 3 is a partially cutaway perspective view of a cone according to another example of the embodiment. In the figure, 1f is a thin film. A thin film 1f is formed integrally with the cone 1 on the mold side of the insertion hole 1a of the cone 1, and the insertion hole 1a is closed until before use. During use, the thin film 1f is pierced and inserted at the end of the separator 2 so that the cone 1 is prevented from falling off from the separator 2 during the assembly of the mold 3 due to friction caused by the broken film 1f. improves. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.

図４に示すのは、セパレータのストッパとコーン本体との間に介装するワッシャーを備えた実施例の型枠固定用コーンの他の例である。図４は実施例の他の例のコーンの使用状態を示す説明図である。図中、５はワッシャーである。ワッシャー５は金属製で、セパレータ２が挿通できる内径で、且つ延設部１ｄの内側に配置できる外径に形成されている。コーン１はプラスチック製でストッパ１ｂは段差が小さいから、締め付けた際に強度的な不安があるが、金属製のワッシャー５を介装することで、大きな荷重が作用されても十分に耐えうるものとなる。その他、符号、構成、作用効果は実施例と同じである。   FIG. 4 shows another example of the mold fixing cone of the embodiment provided with a washer interposed between the separator stopper and the cone body. FIG. 4 is an explanatory view showing a use state of the cone of another example of the embodiment. In the figure, 5 is a washer. The washer 5 is made of metal, has an inner diameter through which the separator 2 can be inserted, and an outer diameter that can be disposed inside the extending portion 1d. Since the cone 1 is made of plastic and the stopper 1b has a small step, there is a fear of strength when tightened, but by inserting a metal washer 5, it can sufficiently withstand even when a large load is applied. It becomes. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.

図５に示すのは、挿通孔の型枠側をセパレータが折り取りできる内径に拡径した実施例の型枠固定用コーンの他の例である。図５は実施例の他の例のコーンの使用状態を示す説明図である。挿通孔１ａの型枠側はセパレータ２が折り取りできる内径に大きく拡径している。セパレータ２を折り取る際、前記実施例では予めコーン１を取り外す必要があったが、空間が広く且つセパレータ２を軸支している挿通孔１ａが短いから、コーン１を装着したままセパレータ２を折り取ることができ、作業が省力化される。その他、符号、構成、作用効果は実施例と同じである。   FIG. 5 shows another example of the mold fixing cone of the embodiment in which the mold side of the insertion hole is expanded to an inner diameter that allows the separator to be broken. FIG. 5 is an explanatory view showing a use state of the cone of another example of the embodiment. The mold hole side of the insertion hole 1a is greatly expanded in diameter so that the separator 2 can be broken. When the separator 2 is folded, it is necessary to remove the cone 1 in advance in the above embodiment. However, since the space is wide and the insertion hole 1a supporting the separator 2 is short, the separator 2 is attached with the cone 1 attached. It can be broken up, saving labor. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.
