Self-separation concrete vibrating bar adopting cold type water drainage technology

Abstract

The invention discloses a self-separation concrete vibrating bar adopting a cold type water technology, and belongs to the technical field of concrete processing. According to the scheme, through thevibration of a vibrating end in the working process, and a release ball frame can be promoted to slide along a side auxiliary rod, so that a movable ball is promoted to slide along the release ball frame; barium hydroxide octahydrate powder in the release ball frame is promoted to be released and react with ammonium chloride powder in the vibrating end; on the one hand, a large amount of ammonia gas can be generated by means of the reaction of the barium hydroxide octahydrate powder and the ammonium chloride powder, so that an elastic sealing film is promoted to expand, protrusions are formedon the surface of the vibrating end, and concrete remains on the surface of the vibrating end is separated; and on the other hand, by means of the heat absorption effect in the reaction process, the temperature in the vibrating end can be rapidly reduced, and water drops can be formed on the surface of the vibrating end by means of the property that water vapor is liquefied when meeting cold, so that the cleaning efficiency of the surface of the vibrating end is improved.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to a self-detachment concrete vibrating rod with cold hydrophobic technology. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete, and the concrete strength grade is based on the standard value of cubic compressive strength Classification, China's ordinary concrete strength grades are divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80, the fine aggregate of the prepared concrete is...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, after the concrete is poured, the vibrating rod needs to be used to vibrate the concrete, so as to promote the compact bonding of the concrete, but after use, there will be some concrete remaining on the surface of the vibrating rod, so the vibrating rod is usually idling, thereby promoting its The remaining concrete on the surface is detached, but the effect is not good, and the vibrator may reduce the service life of the vibrator if it is idle for a long time
