Survey the kind of various vibrators.
So far, mainly, although explanation of vibrator (mainly poker vibrator) and concrete has been given, the method of giving vibration is variously considered by the kind of structure, the situation of the mold of the site, etc.
A vibrator is inserted into concrete mix, direct vibration is given, and concrete placement is performed.
A vibrator (vibration motor) is attached in a mold outside, or external vibrators, such as KC type, are contacted from the outside of a mold, and concrete placement is performed.
A vibrator is applied to the concrete surface, concrete placement and surface finish are performed, and it is used by concrete pavement etc.
A mold is put on a vibration table and concrete placement is performed by vibration of the whole mold.
When these all directions formula is classified into the kind of concrete vibrator
Although there are the form and size of vibrators variously, most things, which a vibration part is the cylindrical form, are mostly used. Eccentric weight built in HBM-ZX high frequency series, handy vibrator series and pendulum movement HV system are mostly used.
It is divided roughly into the HKM and KM series that are called vibration motor, the IRON, WOODPECKER and KC/KD that are used as simple mount vibrator for building wall and the handy vibrator KC/KD series. They are used for the precast concrete, the place that no internal vibrator can use, and/or finish of building wall.
There are R3 series, which carried engine on the vibration stand and/or a thing that attached the vibration motor in aluminum board directly. It is widely used for placement of road pavement, a floor, etc. and surface finish.
It is mainly used as plant equipment for manufacture of a concrete secondary product. For small and middle-scale products, generally electric vibrator is used, and there are a low cycle unit for injection and placement of the concrete mix and a high frequency unit for surface finish. When loading mass must become 5 - 7t or more or it must correspond to reduce placing noise, mostly hydraulic system is used.
