A kind of self-heating vibrator used for concrete pounding

Abstract

The invention discloses a self-heating type vibrating rod for concrete drumming, which belongs to the field of concrete vibration technology. By circularly distributing a plurality of groups of vibrating balls on the outer wall of a hollow rod body, the lifting rod moves up and down, and the bar-shaped teeth With synchronous lifting movement, the vibrating ball installed with multiple heat conduction rods is driven by the arc-shaped toothed belt to turn up and down on the outside of the hollow rod body, which effectively vibrates the concrete. The gas ring-shaped exhaust part effectively discharges the gas in the concrete into the hollow rod during the vibration of the concrete. On the one hand, it effectively reduces the gas in the concrete and reduces the amount of air bubbles in the concrete. On the other hand, the air introduced and the vibration The self-heating layer filled inside the ball reacts to provide a reaction medium for the self-heating layer, so that the self-heating layer generates heat to provide heat for the vibrating ball, and evenly distributes the heat to the concrete, effectively realizing a more comprehensive heating and heat preservation treatment for the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete vibration, in particular to a self-heating vibrator used for concrete vibration. Background technique [0002] In the field of building construction, the vibrating rod is one of the commonly used vibrating devices in concrete pouring. During the concrete pouring process, since the stirred concrete contains a large amount of gas and water, the vibrating rod generates high-frequency vibration inside the concrete, which makes the concrete compact and thus ensures the pouring quality. However, during construction in winter or in some alpine regions, the temperature of concrete is likely to drop suddenly after pouring, and the heat will be lost quickly, which will cause the pouring temperature on the concrete pouring surface to be lower than the design requirement; in addition, due to the low ambient temperature during construction, the concrete During the pouring process, the difficulty of temperatu...

Problems solved by technology

However, only by adding a heating device on the vibrating rod, the heating device is installed at a certain position of the vibrating rod. Due to the low temperature construction environment, the heat is lost quickly. After the heating device is started, the vibrating rod cannot be heated evenly, so it is difficult More comprehensive heating and insulation treatment of concrete
