Self-heating vibrating rod for concrete tamping

Abstract

The invention discloses a self-heating vibrating rod for concrete tamping, and belongs to the technical field of concrete vibration. According to the self-heating vibrating rod for concrete tamping, multiple groups of vibrating balls are annularly distributed on the outer side wall of a hollow rod body, a lifting rod moves up and down, a strip-shaped toothed belt moves up and down synchronously, and an arc-shaped toothed belt drives the vibrating ball provided with multiple heat conduction rods to overturn up and down on the outer side of the hollow rod body, so that concrete is effectively vibrated; and meanwhile, an annular exhaust part used for exhausting air of the concrete is arranged on the outer side of the hollow rod body, so that the air in the concrete is effectively exhausted into the hollow rod body in the concrete vibrating process, in this way, the air in the concrete is effectively reduced, and the amount of bubbles in the concrete is further reduced; and meanwhile, theintroduced air reacts with self-heating layers filling the interiors of the vibrating balls so as to provide a reaction medium for the self-heating layers, so that the self-heating layers emit heat toprovide heat for the vibrating balls, the heat is uniformly dissipated into the concrete, and therefore comprehensive heating and heat preservation treatment on the concrete is effectively realized.

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, resulting in the pouring temperature on the concrete pouring surface being lower than the relevant requirements; in addition, due to the low ambient temperature during construction, resulting in concrete During the pouring process, the difficulty of t...

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
