Surface point vibration type vibrating rod

Abstract

The invention discloses a surface point vibration type vibrating rod, and belongs to the field of vibrating rods. According to the surface point vibration type vibrating rod, an outer micro-vibration hard shell is arranged and matched with the action of an air-blowing compression ring, the air-blowing compression ring is pinched during vibrating, compressed air in the air-blowing compression ring is dispersed into an air vibration cavity through a U-shaped air dispersion cavity, an air vibration rebounding ball is driven to impact the outer micro-vibration hard shell, so that the multi-point micro-vibration phenomenon occurs on the surface of the outer micro-vibration hard shell, on one hand, micro-vibration of concrete slurry near the vibrating rod is effectively accelerated, outward overflow of air near the vibrating end is accelerated, therefore small gaps near the vibrating rod are effectively eliminated, the concrete density after vibrating is higher, and the vibrating effect is better; and on the other hand, adhesion of concrete slurry on the surface of the concrete is effectively reduced, meanwhile, after vibration is finished, part of the adhered concrete slurry can fall off through vibration, and the influence of manual cleaning on the construction efficiency is effectively avoided.

Description

technical field [0001] The invention relates to the field of vibrating rods, more specifically, to a surface point vibration type vibrating rod. Background technique [0002] The vibrating rod is also called the vibrating rod, which is composed of cables (with leakage protector), driver, (220V) rubber tube, vibrating rod (built-in motor) and other components. Using low-voltage (safety voltage 42V) high-frequency (200Hz) power supply, a micro-motor is directly built into the plug-in vibrating rod to drive the eccentric block, and the vibration frequency is as high as 12,000 times per minute, which is very easy to resonate with the concrete component and cause air bubbles in the component Quickly discharged, the cement, sand and steel frame are closely integrated to achieve the compactness of the concrete and high surface finish. [0003] Although the vibrating rod can effectively eliminate most of the voids and air bubbles in the concrete, in actual operation, there will sti...

AI Technical Summary

Problems solved by technology

[0003] Although the vibrating rod can effectively eliminate most of the voids and air bubbles in the concrete, in actual operation, there will still be some small voids in the concrete slurry, which still have a certain impact on the strength of the formed concrete block, especially It is the concrete slurry near the vibrating end of the vibrating rod. The large vibration effect here will cause part of the outside air to be introduced into this place, and part of the air will not overflow with the vibrating rod when it is taken out, resulting in a certain small gap. In addition, the surface of the vibrating rod is easy to adhere to a certain amount of concrete slurry, which causes the construction personnel to manually clean and remove it, which affects the construction efficiency
