Pier column group bar vibrator capable of automatically and synchronously lifting and usage method

Abstract

A pier column group bar vibrator capable of automatically and synchronously lifting comprises a lifting device, vibrating bars and a steel plate ring, and crossed supporting rods are arranged in the steel plate ring; a vibrating rod fixing sleeve is arranged at the intersection point of the supporting rods; a plurality of vibrating rod fixing sleeves are further arranged on the outer side of the steel plate ring; the vibrating rod fixing sleeve is used for fixing the vibrating rod; the lifting device is connected to the supporting rod through a steel wire rope so as to lift the steel plate ring and the vibrating rod. The pier column group bar vibrator capable of automatically and synchronously lifting is simple in structure and convenient to operate. The multiple vibrating rods are adopted for vibrating at the same time, the vibrating time is greatly shortened, concrete is vibrated in all directions, the vibration missing phenomenon is avoided, bubbles in the pier column are fewer, the service life is prolonged, and the construction cost is reduced. The touch frequency of the vibrating rod and the steel bar framework can be effectively reduced, and the qualification rate of a steel bar protective layer can be controlled. An automatic lifting mode is adopted for vibrating, so that the labor investment is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of road and bridge pier column construction, and in particular relates to an automatic synchronous lifting pier column group rod vibrator and a use method. Background technique [0002] With the development of the economy, the basic construction of our country is also developing continuously, and at the same time, new standards and requirements are put forward for the basic construction of our country. [0003] The pier columns of road bridges generally adopt the traditional high-performance concrete construction technology. The vibration link of the traditional construction technology generally uses a vibrating rod for vibration. However, the vibration efficiency of this method is low, which greatly increases the time cost and takes a long time. The time-consuming work increases the labor cost, and there are more air bubbles on the surface. The piers vibrated by this method have more air bubbles on the surf...

Problems solved by technology

[0003] The pier columns of road bridges generally adopt the traditional high-performance concrete construction technology. The vibration link of the traditional construction technology generally uses a vibrating rod for vibration. However, the vibration efficiency of this method is low, which greatly increases the time cost and takes a long time. The time-consuming work increases the labor cost, and there are more air bubbles on the surface. The pier column after vibrating in this way has more air bubbles on the surface, and it is very easy to cause local leakage and over-vibration phenomena. There are often rework and repair phenomena, and the pier column The service life is low, which increases the construction cost
