Rib-imitated self-unfolding and folding type concrete vibrating rod

Abstract

The invention discloses an umbrella-rib-imitated self-unfolding and folding type concrete vibrating rod, belongs to the field of concrete vibrating rods. The umbrella-rib-imitated self-unfolding and folding type concrete vibrating rod comprises a vibrating rod body and a connecting pipe with one end connected to vibrating equipment. During insertion, a folded state is adopted, small-size insertionis achieved, vibration compaction on surface concrete is effectively reduced, in the vibration process, the device is gradually converted into an unfolded state from the folded state, large-range vibration compaction on the concrete is achieved, and meanwhile through the magnetic umbrella rib wrapping rods in the unfolded state, the vibration compaction effect on the concrete is improved, a large-volume space area formed in the extraction process of the device is divided into a plurality of small-volume space areas which are not communicated with one another, so that the filling efficiency and the filling time of concrete are greatly reduced, the situation that the extraction space is not fully filled with the concrete is reduced, and the compactness of the concrete is improved.

Description

technical field [0001] The invention relates to the field of concrete vibrating rods, in particular to a self-expanding and retracting concrete vibrating rod imitating umbrella ribs. Background technique [0002] When using a concrete mixer to mix the concrete and pour the components, it is necessary to remove the air bubbles and tamp them to make the concrete compact and eliminate the honeycomb pitting of the concrete, so as to improve its strength and ensure the quality of the concrete components. The process of eliminating air bubbles and performing tamping is concrete vibration [0003] When using a plug-in vibrator, it should be inserted quickly and pulled out slowly. The insertion points should be evenly arranged, moved point by point, and carried out in sequence, without omission, so as to achieve uniform vibration. The vibration depth of the inserted vibrating rod is generally not more than 2 / 3 to 3 / 4 times the length of the vibrating rod. For the two layers, the lo...

Problems solved by technology

[0004] The size of the existing vibrating rod should not be too thick or too thin, because although the thicker vibrating rod has a larger vibrating range, the space formed when it is pulled out is larger, and the space is not easy to fill, resulting in gaps, while the thinner vibrating rod When the vibrating rod is pulled out, the space area formed is small, but the vibrating range is correspondingly small, and the vibrating effect is low. Therefore, the size of the existing vibrating rods is fixed within a certain range and cannot be adjusted.

Even if such a vibrator is "slowly drawn", it is easy for the concrete not to fill the space drawn out by the vibrator, resulting in voids in the concrete
