Description

TECHNICAL FIELD

[0001] The present application belongs to the field of concrete vibrating rod, more particularly, to a telescopic, foldable and multi-point expandable vibrating rod and construction method. BACKGROUND

[0002] Nowadays, concrete is often used in construction engineering. When pouring components, vibrating rod must be used to remove air bubbles in concrete, so as to achieve dense combination of concrete and ensure the quality of concrete components. Vibrating rod uses eccentric block rotation vibration to produce resonance with concrete components, so that air bubbles are quickly removed.

[0003] In the prior art, in order to enable the vibrating rod to quickly pass through the embedded steel support in the pouring process, the vibrating rod is generally a vertical long rod, the vibrating area is small, the vibrating rod needs to be frequently inserted and pulled out, the vibrating frequency is large, and the efficiency of concrete vibration is seriously reduced. In some areas, the steel reinforcement frame is large, the gap between the steel reinforcements is small, the diameter of the ordinary vibrating rod is large, and the vibrating rod cannot be inserted into the steel reinforcement frame to reach the lower concrete area. This causes missed vibration or incomplete vibration, which affects the quality of concrete.

[0004] In the prior art, the flexible device and the expansion liquid used in some designs are easily damaged by sharp objects, which causes the expansion liquid to leak and pollute the concrete. In addition, although some designs can improve the density of concrete during extraction, the vibration range is limited, and only single-point vibration is allowed, which results in low work efficiency.

[0005] The present application improves the vibrating efficiency by using the method of installing multiple vibrating rods; the vibrating end with a small diameter can be applied to various steel reinforcement frame environments, and the application range is wide; the telescopic vibrating head can be applied to the vibrating requirements of concrete components with different depths.

The vibrating end of the application is miniaturized, and the diameter is set to about 2-3 centimeters, so it can be inserted into any steel reinforcement framework (according to the steel reinforcement binding specification, the thickness of the protective layer of the steel reinforcement should not be less than 2 centimeters), and the concrete in the steel reinforcement framework is fully vibrated, and the overall structure of the steel reinforcement framework is not affected, and the binding and position of the steel reinforcement framework are not damaged and do not produce displacement phenomenon.

[0043] Please refer to FIG. 1, the device of the application comprises a driver 21, a power connection pipe 22, a folding end 23, a straight end 24, a vibrating end 25; the driver 21 provides power, which is transmitted to the straight end 24 through the power connection pipe 22 (the left end transmission gear 17 and the right end transmission gear 15 are rotated by the input gear 16), the vibrating end 25 is connected to the straight end 24 and the folding end 23, the rotating screw 14 in the straight end 24 and the folding end rotating screw 27 in the folding end 23 drive the vibrator gear 1 in the vibrating end 25 to rotate, and drive the eccentric vibrator 7 to rotate, thereby generating a vibrating force.
