High-efficiency concrete vibrating bar folding and stretching based on reactive force

Abstract

The invention provides a high-efficiency concrete vibrating bar folding and stretching based on reactive force, and relates to the technical field of concrete leveling. The high-efficiency concrete vibrating bar folding and stretching based on the reactive force comprises a hose, wherein one end of the hose is in threaded connection with a steel pipe bar; a sleeve is fixedly installed at the periphery of the steel pipe bar; a sliding plate is slidably connected at the periphery of the sleeve; a lifting rod is fixedly installed at the inner side of the sliding plate; lower folding rods are rotatably connected to the outer side of the bottom end of the lifting rod; and upper folding rods are rotatably connected to the other ends of the lower folding rods. According to the high-efficiency concrete vibrating bar folding and stretching based on the reactive force, the acting area of the vibrating bar is increased while the steel pipe bar is not prevented from extending into a steel bar support, so that the working efficiency of the vibrating bar is improved, and the extending length of the steel pipe bar is adjusted; and the vibration of the hose is buffered, so that the stimulation tohands is relieved, and the working strength is reduced.

Description

technical field [0001] The invention relates to the technical field of concrete leveling, in particular to a high-efficiency concrete vibrating rod that is folded and stretched based on reaction force. Background technique [0002] At present, in the concrete pouring construction, in order to ensure the uniform distribution of the concrete, improve and increase the structural strength of the concrete after solidification, it is necessary to vibrate the concrete while performing the concrete pouring operation, especially in the construction of some large concrete buildings. Vibration is particularly important, and the construction machinery to be used is the concrete vibrator. [0003] In order to allow the concrete vibrating rod to pass through the buried steel support during the pouring process, the traditional vibrating rods are all vertical strips, but the area of ​​vibration is greatly reduced, and multiple areas of the concrete need to be reciprocated. Inserting the vi...

[0003] In order to allow the concrete vibrating rod to pass through the buried steel support during the pouring process, the traditional vibrating rods are all vertical strips, but the area of ​​vibration is greatly reduced, and multiple areas of the concrete need to be reciprocated. Inserting the vibrator reduces the efficiency of concrete vibrating. At the same time, during the vibrating operation, the constructor needs to hold the hose all the time for operation, but the hose will also vibrate. After a long period of construction, it is easy for the constructor to Vibration numbness in hands, strong construction strength
