(57) [Summary] (Corrected) [PROBLEMS] To provide an air bubble remover for preventing a molding surface from becoming an avatar surface due to air bubbles adhering to an inner surface of a form during concrete molding. An air bubble remover having a small through-hole (2) formed on the entire surface of a stainless steel blade-shaped flat plate (1), wherein the air bubble is provided on the flat surface by inserting it into the inner surface of a mold and pulling it up. Since it is erased by the through-hole and stroked by the flat plate, the molding surface is finished to a smooth surface.

【考案の詳細な説明】 【0001】 【考案の属する技術分野】 本考案はコンクリート成形において型枠の内側に付着する気泡を除去する泡取 り器に関する。 【0002】 【従来の技術】 コンクリート成形において型枠板の内側に気泡が付着することは常に見られる 現象であって、これは投入されるコンクリートに含まれている空気あるいは水分 によるものであって、成形に際して振動を加えて締固めを行っても、この付着し ている気泡は全く無くなることはない。 【0003】 振動締固めによってコンクリート中の空気は分散されて殆どは上面から抜ける が、この細分化した空気は細い気泡となって、かえって型枠の内側に付着する傾 向にある。 【0004】 【考案が解決しようとする課題】 このため、さらに振動を加勢するか、搗き固め手段を加えるが、一旦型枠に付 着した気泡は仲々除去することができず、そのままで脱型する。このとき成形さ れたコンクリート面には気泡による凹面(アバタ)が生じて見た目が悪く、この アバタが多い場合は改めてコテ塗りして修正するが、殆どの場合はそのままにし て完成とする。 【0005】 【課題を解決するための手段】 考案者はこの点に鑑み種々試作研究を続けた結果本考案に到達したものであっ て、本考案は細長いステンレス製の平板に多数の透孔を設け、この平板を型枠の 内側に沿って挿入し、引き抜くことによって、型枠に付着している気泡の殆どを 取り除くのに成功した。 【0006】 【考案の実施の形態】 添付図面により本考案の実施の形態を説明すると、図1は本考案の泡取り器の 平面図であって、先細りの細長い刃剣状の平板(1)で一方に握り部(3)を設 けてあり、また平板(1)の部分には多数の透孔(2)を設ける。この図1は作 図上刃剣状の平板を横形に示しているが、使用に当っては図2に示しているよう に握り部(3)を持って使用する。 【0007】 図2は使用の状態を示す実施例図であって、型枠KにコンクリートCを打設投 入した一部を示していて、この型枠Kの内面に沿ってコンクリートCの中に本考 案の泡取り器(1)を矢印のように挿入し、矢印のように引き抜くこととす る。 【0008】 【実施例】 図1は本考案の泡取り器の平面図であり、(1)は先細りとしたステンレス鋼 製の細長い平板であって、長さは任意であるが、取扱いに適した80cm程度と する。幅は約10cmで厚さは強度を持たせるためと、気泡を採取し易くするた め3mmとやや厚めにする。また平板部(1)に設ける透孔(2)は径が10m m位とし、多数設けることによって気泡の引出しの効率をよくする。そしてこの 一方端に握り部(3)を設ける。 【0009】 図2は使用の状態を示す実施例図であり、Kは型枠を示し、Cは打設コンクリ ートである。本考案の泡取り器は、この型枠Kの内側面のコンクリートの中に矢 印A−のように挿入して、同じく矢印A−のように引き抜くもので、この時 型枠Kの内面に付着している気泡(図示していない)は透孔(2)に引っ掛けら れてコンクリートの中に拡散するか、透孔(2)の中に入って引出されて付着し ている気泡は除去される。 【0010】 この気泡除去の操作は、型枠内面に沿って順に移動して行うことによって成形 されるコンクリート面全体に行うものであり、これによりコンクリート面はアバ タ面が無くなるばかりか、平板によって撫でられるためコテ仕上げを行ったよう な滑面に仕上る。 【0011】 【考案の効果】 上述のように本考案の泡取り器は、コンクリート成形に際して型枠の内側面に 沿って本考案の泡取り器を挿入して引き抜くことによって、型枠に付着している 気泡は泡取り器に設けられている透孔によって、潰されるか、孔によって引出さ れて除去される。 【0012】 したがって脱型後のコンクリート面は気泡によるアバタ面が無くなり、しかも 刃剣状の平板で撫でられるため滑面に成形されて仕上りがよくなるという形成上 の作用効果を奏する。[Detailed description of the invention] [0001] [Technical field to which the invention belongs]   The present invention is a foam removing device for removing air bubbles adhering to the inside of a form in concrete molding. Related to the device. [0002] [Prior art]   Air bubbles are always seen inside the form plate in concrete molding This is a phenomenon that is caused by air or moisture contained in the concrete Even if compaction is performed by applying vibration during molding, There are no bubbles at all. [0003]   Vibration compaction disperses air in the concrete and mostly escapes from the top However, this fragmented air becomes fine bubbles, which in turn tend to adhere to the inside of the mold. In the direction. [0004] [Problems to be solved by the invention]   For this reason, additional vibration or grinding means is added, but once the The attached bubbles cannot be removed gradually, and are removed as they are. This time molded The concave surface (avatar) caused by air bubbles on the concrete surface If there are many avatars, iron them again and fix them. To complete. [0005] [Means for Solving the Problems]   In view of this point, the inventor of the present invention reached the present invention as a result of continuing various trial production research. In the present invention, a long and thin stainless steel plate is provided with many through holes, and this plate is By inserting along the inside and pulling out, most of the air bubbles adhering to the formwork Successfully removed. [0006] [Embodiment of the invention]   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, an embodiment of the present invention will be described. FIG. 3 is a plan view showing a grip portion (3) provided on one side by a tapered and elongated blade-like sword-shaped flat plate (1). The plate (1) is provided with a large number of through holes (2). This figure 1 In the figure, the blade-like sword-like flat plate is shown in a horizontal shape, but in use, as shown in FIG. Hold the handle (3). [0007]   FIG. 2 is an embodiment diagram showing a state of use. The inside of the form K is shown in concrete C along the inner surface of this formwork K. Insert the defoamer (1) as shown by the arrow and pull it out as shown by the arrow. You. [0008] 【Example】   FIG. 1 is a plan view of the defoamer of the present invention, and (1) is a tapered stainless steel. It is a slender flat plate made of stainless steel. The length is arbitrary, but it is about 80 cm suitable for handling. I do. The width is about 10 cm and the thickness is to make it easier to collect air bubbles to make it strong. 3mm slightly thicker. The diameter of the through hole (2) provided in the flat plate portion (1) is 10 m. By setting the number to about m, the efficiency of air bubble extraction is improved by providing a large number. And this A grip (3) is provided at one end. [0009]   FIG. 2 is an embodiment view showing a use state, in which K indicates a formwork, and C indicates a casting concrete. It is. The defoamer of the present invention uses arrows in concrete on the inner surface of this formwork K. Insert it as shown by the mark A- and pull it out as shown by the arrow A-. Bubbles (not shown) adhering to the inner surface of the mold K are caught in the through holes (2). To diffuse into concrete, or to enter through-hole (2) Bubbles are removed. [0010]   This bubble removal operation is performed by sequentially moving along the inner surface of the mold This is done on the entire concrete surface to be Not only the surface is gone, but it was ironed because it was stroked by a flat plate Finish on a smooth surface. [0011] [Effect of the invention]   As described above, the defoamer of the present invention is applied to the inner surface of the form during concrete molding. Attached to the formwork by inserting and removing the defoamer of the present invention along Bubbles can be crushed or pulled out by perforations in the defoamer. Removed. [0012]   Therefore, the concrete surface after demolding has no avatar surface due to air bubbles. Because it is stroked with a blade-shaped plate, it is formed on a smooth surface and the finish is improved The operation and effect of
