Internal extrusion synchronous backfill type concrete vibrating rod

Abstract

The invention discloses an internal extrusion synchronous backfill type concrete vibrating rod, and belongs to the field of concrete vibrating rods. The internal extrusion synchronous backfill type concrete vibrating rod comprises a vibrating rod and a connecting pipe with one end connected to vibrating equipment wherein, a lead is connected between the other end of the connecting pipe and the vibrating rod, and a top tray is fixedly connected to the lower end of the connecting pipe. In the vibrating process, through rotating dislocation of a dislocation flow control barrel, concrete is controlled to enter and exit from the inner part of the dislocation flow control barrel, filling of the concrete in the dislocation flow control barrel is achieved, and in the process of taking out the vibrating rod, a special-shaped elastic squeezer automatically squeezes the concrete in the dislocation flow control barrel, so that the concrete synchronously flows out from the lower end of the dislocation flow control barrel in the process of taking out the vibrating rod and is stuffed into space formed by drawing out the vibrating rod, the situation of internal gaps of the concrete due to drawingout of the vibrating rod is effectively reduced, the compactness of the concrete is greatly improved, and a high-quality concrete molded body is obtained.

Description

technical field [0001] The invention relates to the field of concrete vibrating rods, in particular to an internal extrusion synchronous backfilling concrete vibrating rod. Background technique [0002] When using a concrete mixer to mix the concrete and pour the components, it is necessary to remove the air bubbles and tamp them to make the concrete compact and eliminate the honeycomb pitting of the concrete, so as to improve its strength and ensure the quality of the concrete components. The process of eliminating air bubbles and performing tamping is concrete vibration [0003] When using a plug-in vibrator, it should be inserted quickly and pulled out slowly. The insertion points should be evenly arranged, moved point by point, and carried out in sequence, without omission, so as to achieve uniform vibration. The vibration depth of the inserted vibrating rod is generally not more than 2 / 3 to 3 / 4 times the length of the vibrating rod. For the two layers, the lower concre...

Problems solved by technology

[0004] However, when pulling out the vibrator, even if the "slow pull" is achieved, it is easy for the concrete to not fill the space drawn out by the vibrator, resulting in voids in the concrete
