PURPOSE: To fix the whole of a vibrator to the surface of a form to perform concrete vibration work by connecting a suction cup-shaped fixing means to a suction pump through a hose or pipe and subsequently sucking air to bring the fixing means to a vacuum state to such the same to the surface of the form. CONSTITUTION: The fixing means 22 for holding the vibration means 21 of a vibrator 20 to a form is constituted so that one end surface 23 thereof is opened and the other end surface 24 thereof is formed into a hermetically closed disc shape and a seal material 234 is provided to the opening end surface 23 along the entire periphery of a circumferential part 230. The passage 241 communicating with the opening end surface 23 is provided to the hermetically closed end surface 24 and an adaptor 26 having an adjusting valve 27 attached thereto is provided to the part of the passage 241 outwardly projected from the hermetically closed end surface 24 and the fixing means 22 is connected to the suction pump through the adaptor 26 by a hose or pipe. By the suction pump, the fixing means 22 is brought to a vacuum state and the suction cup structure is utilized to suck the surface of the form and vibration work can be performed and, by cutting off suction, the detachment from a fixed position and simple movement can be performed. |
