「産業上の利用分野」
本考案は、打設コンクリートの表面気泡を除去
するスページングバイブレータに係るものであ
る。[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a spacing vibrator for removing air bubbles from the surface of poured concrete.
「従来の技術と考案が解決しようとする問題点」
コンクリート打設における打放し仕上げの場
合、特に、表面気泡が生じないように配慮され
る。``Problems to be solved by conventional techniques and ideas'' In the case of exposed finishing when pouring concrete, particular care must be taken to prevent the formation of surface bubbles.
この表面気泡の排除には、通常、棒状バイブレ
ータや突き棒やたたき木等が用いられているが、
十分ではなく、適当な装置、工具の開発が望まれ
ている。 To eliminate these surface air bubbles, a rod-shaped vibrator, a push rod, a wood pound, etc. are usually used.
However, there is a need for the development of appropriate equipment and tools.
本考案は、斯る要望を満足せしめようとするも
のである。 The present invention attempts to satisfy such demands.
「問題点を解決するための手段」
本考案は、棒状バイブレータ１の振動部１１
に、正面を平坦面２１、両側面及び下面を傾め後
方に面する傾斜面２２，２２，２３に形成したヘ
ラ２を装着して成る。"Means for Solving Problems" The present invention is based on the vibrating part 11 of the rod-shaped vibrator 1.
A spatula 2 having a flat front surface 21 and sloped surfaces 22, 22, 23 facing rearward on both side and lower surfaces is attached to the body.
「作用」
如上の構成であり、使用に当たつては、コンク
リートの打設直後に、ヘラ２の平坦面２１を型枠
３のせき板３１内面に当接させて、該ヘラ共々振
動部１１を打設コンクリート４中へ進入させれば
よい。"Operation" The structure is as described above, and in use, immediately after pouring concrete, the flat surface 21 of the spatula 2 is brought into contact with the inner surface of the weir plate 31 of the formwork 3, and the spatula and the vibrating section 11 are brought into contact with each other. may be allowed to enter into the poured concrete 4.
斯様にして進入させると、ヘラ２は、両側面及
び下面が傾斜面２２，２２，２３であることか
ら、打設コンクリート４による水平反力を受けて
平坦面２１がせき板３１の表面に押し付けられ

ト４から上方への反力A0を受け、この反力A0は、
せき板３１へ向かう水平分力A1と傾斜面２３に
沿つた摩擦抵抗A2との合力であるから、その水
平分力A1（水平反力）により、へら２はせき板３
１へと押し付けられる。また、第５図に示すよう
に、へら２がせき板３１に沿つて左右いずれか一
方へと横方向にＢの力で進行するときは、その進
行側の傾斜面２２が打設コンクリート４から反対
方向への反力B0を受け、この反力B0は、せき板
３１へ向かう水平分力B1と傾斜面２２に沿つた
摩擦抵抗B2との合力であるから、その水平分力
B1（水平反力）により、へら２はせき板３１へと
押し付けられる。その結果、ヘラ２の平坦面２１
がせき板３１の表面を擦り、これに振動部１１か
らのバイブレーシヨンが加わつて、表面気泡が排
出される。 When the spatula 2 is advanced in this manner, since both side surfaces and the bottom surface are sloped surfaces 22, 22, 23, the flat surface 21 receives the horizontal reaction force from the poured concrete 4, and the flat surface 21 touches the surface of the weir plate 31. Being pushed. In other words, as shown in FIG. 4, when the spatula 2 moves downward along the weir plate 31 with force A, the inclined surface 23 at the lower end of the spatula 2 receives an upward reaction force from the poured concrete 4. A 0 is received, and this reaction force A 0 is
Since this is the resultant force of the horizontal component force A 1 directed toward the weir plate 31 and the frictional resistance A 2 along the slope 23, the spatula 2 is moved toward the weir plate 3 by the horizontal component force A 1 (horizontal reaction force).
Pushed to 1. Further, as shown in FIG. 5, when the spatula 2 moves laterally to either the left or right side along the weir plate 31 with force B, the inclined surface 22 on the advancing side moves away from the poured concrete 4. Reaction force B 0 in the opposite direction is received, and this reaction force B 0 is the resultant force of the horizontal component force B 1 directed toward the weir plate 31 and the frictional resistance B 2 along the slope 22, so the horizontal component force
The spatula 2 is pressed against the weir plate 31 by B 1 (horizontal reaction force). As a result, the flat surface 21 of the spatula 2
The surface of the baffle plate 31 is rubbed, and vibration from the vibrating section 11 is added to this to expel air bubbles from the surface.
