Technical Field

The invention relates to the field of concrete vibrating rods, in particular to an umbrella rib-imitated self-unfolding folding type concrete vibrating rod.

Background

When the concrete mixed by the concrete mixer is used for pouring the member, the air bubbles in the concrete must be removed and the member must be tamped to make the concrete compact and combined, thereby eliminating the phenomena of the honeycomb pitted surface and the like of the concrete, improving the strength of the member and ensuring the quality of the concrete member

The use of the plug-in vibrating rod is to insert quickly and pull slowly, the insertion points need to be uniformly arranged and move point by point in sequence, omission is avoided, and uniform compaction is achieved. The vibration depth of the inserted vibrating rod is generally not more than 2/3-3/4 times of the length of the vibrating rod, and for the two layers, the lower layer concrete is inserted by 5-10 cm to eliminate the joint gap between the two layers. The moving distance is not more than 1.5 times of the action radius of the vibrating rod, and when the concrete is vibrated, the purpose of 'fast inserting and slow pulling' is realized: the quick insertion is to prevent the surface concrete from being compacted firstly and from layering and segregation with the lower layer concrete; the slow pulling is to make the concrete to fill the space formed when the vibrating rod is pulled out.

The size of current vibrating rod can not be too thick nor too thin, because thicker vibrating rod is bigger in the scope of vibrating, but the space that forms when taking out is great, thereby the space is difficult for filling up and produces the space, and thinner vibrating rod is regional little in the space that forms when taking out, but its scope of vibrating is also corresponding less, and the effect of vibrating is low, therefore its size of current vibrating rod all fixes the setting in certain extent, can not adjust. Even if the vibrating rod is pulled out slowly, the concrete is not filled in the space where the vibrating rod is pulled out, and gaps exist in the concrete.
