Description
The present invention relates to a vibrator apparatus, system, method of casting, and a pile of concrete constructed by placing the concrete, which can be moved.
Generally, the technology of making various blocks and formworks by using concrete mortar has been widely used for a long time in architecture, civil engineering field and so on.
These concrete formworks are filled with concrete mortar in the same shape form, then cured for a certain period of time.
In this case, if the concrete mortar filled in the mold is not completely removed, the durability of the molded product is deteriorated. Therefore, the bubbles remaining in the concrete mortar should be discharged to the outside to obtain a high-quality molded product.
In addition, since reinforcing bars are inserted into the molds for reinforcing the strength, it is understood that the concrete mortar is not interfered by the inserted reinforcing bars and the reinforcing bars are well filled up to every corner of the molds.
In order to solve this problem, it is effective to apply vibration to the concrete mortar filled in the mold to shake it.
FIG. 1 is a partial cross-sectional view of a vibrator in which vibration is applied to a concrete mortar filled in a conventional mold. The
The vibrator includes a
Therefore, one operator holds the end of the flexible hose 8 and the other one operator places the concrete hose close to the
However, in the case of such a conventional vibrator, the insertion depth can not be adjusted, resulting in a difference in the quality of the molded article depending on the skill of the operator.
In order to solve such a problem, Korean Patent Registration No. 1132557 discloses a technique for allowing a vibrator to be moved by a position variable means.
2 is a cross-sectional view of a vibration device for a concrete molding machine disclosed in the prior-art patent document 1132557. Fig. As shown in FIG. 2, the vibration device for a concrete molding machine disclosed in Japanese Patent No. 1132557 includes a plate-

However, even when such a structure is employed, there is a limit to the conventional production of a uniform concrete molded article.
That is, the concrete structure is transported to the site by using the concrete mixer at the factory, and the unhardened concrete is laid, cured for a certain period, and the formwork is removed to construct the completed structure. In order to ensure the strength, durability, and watertightness of the concrete structure and the beauty of the concrete surface, concrete compaction using a concrete vibrator is essential when casting concrete.
However, a conventional concrete vibrator used for uniform compaction, prevention of material separation, and surface defects has many problems because it is composed of a vibration bar, a flexible cable part, and a power supply part.
In other words, since the conventional concrete vibrator is composed of a vibrating rod and a flexible cable part, it is not possible to insert a vibration rod into a desired position according to the shape of the concrete structure, so that the compaction operation is insufficient, It is very difficult to do.
In particular, since the vibrator is vertically inclined, the inclined surface of the inclined form surface is more distant from the form surface as it goes downward, resulting in surface defects such as blisters, bubbles, material separation, .
In addition, there is a problem that the vibrations concentrate on the vibrating rods and vibrate only on the vibrating periphery, which causes the deterioration of the material separation of the concrete.
