Description

Technical Field

[0001] The utility model relates to the technical field of degassing of liquid concrete, and specifically relates to a concrete ultrasonic vibration degassing device. Background Technique

[0002] During construction, when concrete is in a liquid state, it is necessary to remove internal bubbles, mainly based on the following reasons and technical logics:

[0003] The presence of bubbles in concrete has an important impact on its performance. First of all, bubbles will reduce the strength and durability of concrete. Larger bubbles will reduce the cross-sectional volume of concrete, resulting in an incompact internal structure and thus reducing the strength. According to the specification, for every 1% increase in air content, the 28-day compressive strength may decrease by 4% - 6%. In addition, bubbles will also accelerate the carbonation of the concrete surface and affect the corrosion resistance.

[0004] Secondly, bubbles will also affect the appearance quality of concrete. Large bubbles may cause defects such as honeycombing and pitting on the concrete surface, affecting the aesthetics.

[0005] Regarding the formation mechanism of bubbles, it is mainly related to the gas introduced during the concrete mixing process. The air-entraining components in cement grinding aids and water reducers, as well as unreasonable material gradation, may all cause bubbles to be generated. Insufficient or excessive vibration is also one of the reasons for bubble formation.

[0006] During construction, with the development of technology, in order to remove the bubbles in liquid concrete, the latest method is to use ultrasonic waves to remove the bubbles in concrete, that is: construction workers often use an ultrasonic defoamer to remove the bubbles in liquid concrete, and its specific principle is:

[0007] By emitting high-frequency sound waves, vibrations are generated in the liquid, and these vibrations can break the surface tension of the bubbles, causing the bubbles to burst. This is the basis for the ultrasonic defoamer to eliminate bubbles.

[0008] Secondly, concrete is a viscous liquid containing a large number of bubbles. These bubbles will affect its strength and durability after the concrete solidifies. Therefore, before the concrete solidifies, it is necessary to eliminate as many bubbles as possible, so that the bubbles burst before the concrete solidifies, thereby improving the compactness and strength of the concrete.

[0009] However, during the degassing and defoaming process of liquid concrete, the degassing and defoaming method of construction workers using an ultrasonic defoamer is mostly to hold the device by one person and continuously degas and defoam a certain place of the liquid concrete in a single-point form, and this degassing and defoaming method will result in a small coverage area of the ultrasonic waves.

[0010] Based on this, a concrete ultrasonic vibration degassing device is now proposed. Content of the Utility Model

[0130] When the ultrasonic defoamer 17 is disassembled from the annular bracket 16 for use, a construction worker can hold the rear grip 1704 with one hand and the front grip 1707 with the other hand. By pressing the start button 1705 to start the ultrasonic defoamer 17, ultrasonic waves can be emitted through the ultrasonic vibrating head 1703 to perform local degassing and defoaming on the liquid concrete.

[0131] It should be noted that the principle of ultrasonic degassing and defoaming of the ultrasonic defoamer 17 for concrete is well-known to those skilled in the art, and thus its working principle will not be elaborated here.

[0132] In summary, the working process of the present utility model is as follows:

[0133] As Figures 1-13 shown, the frame structures are arranged in two groups and are oppositely arranged. The two groups of frame structures are arranged on one side of the steel frame at the construction site (the steel frame at the construction site is not shown in the figure);

[0134] There are four groups of clamping arm structures, and the four groups of clamping arm structures are respectively installed at both ends of the two groups of frame structures;

[0135] The clamping arm structures at both ends of each group of frame structures are used to clamp the steel frame, so that the two groups of frame structures can be stably fixed and installed on the steel frame at the construction site;

[0136] There are two groups of vertical adjustment structures, and the two groups of vertical adjustment structures are respectively installed on the corresponding frame structures;

[0137] Positioning structures are installed on both groups of vertical adjustment structures, and the two groups of positioning structures are used to position and fix the corresponding vertical adjustment structures;

[0139] The annular bracket 16 is installed on the horizontal reciprocating adjustment structure, and the ultrasonic defoamer 17 is detachably installed on the annular bracket 16;

[0140] Specifically, the ultrasonic defoamer 17 can reciprocate horizontally through the horizontal reciprocating adjustment structure to expand the coverage of the ultrasonic waves of the ultrasonic defoamer 17 in the horizontal direction, and the ultrasonic defoamer 17 can also slide up and down vertically through the two groups of vertical adjustment structures to expand the coverage of the ultrasonic waves of the ultrasonic defoamer 17 in the vertical direction;

[0141] Under the above actions, the ultrasonic waves of the ultrasonic defoamer 17 can degas and defoam the liquid concrete at the construction site in a larger and wider form;

[0142] Specifically, since the ultrasonic degassing device 17 is detachable, in actual applications, construction workers can also remove the ultrasonic degassing device 17 from the annular bracket 16 and manually hold it to perform local degassing and defoaming on the liquid concrete, so as to increase the flexibility of use.

[0143] The above different embodiments can be combined, replaced, and used in combination with each other.
