Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and relates to concrete pouring construction, specifically to a concrete bubble visualization test device. Background Technology

[0002] Quality defects such as air bubbles or honeycomb pitting often appear on the surface of concrete. There are many reasons for these defects. In addition to factors such as raw material problems and unreasonable concrete mix proportions, inadequate vibration during construction and insufficient mixing time can also lead to the formation of air bubbles in the concrete. Furthermore, if the release agent is of poor quality, the air bubbles cannot be expelled from the formwork surface and will accumulate on the concrete surface, forming defects such as air bubbles, honeycomb, and pitting. These defects can only be discovered after the formwork is removed, but by then the concrete construction is complete and it is not easy to repair them. Summary of the Invention

[0003] The purpose of this invention is to provide a concrete air bubble discharge visualization test device to address the above-mentioned problems, observe the effect of concrete air bubble discharge through experiments, optimize concrete construction plans, and ensure construction quality.

[0004] The technical solution of this utility model is as follows:

[0005] A concrete bubble visualization test device is characterized by comprising a bottom formwork, side formwork, and a reinforcing cage. The bottom formwork has multiple main reinforcement positioning tubes vertically arranged according to the spacing of the main reinforcement bars in the reinforcing cage. An annular side formwork positioning groove is provided around each main reinforcement positioning tube. The side formwork is a cylindrical structure made of transparent acrylic sheet, with its bottom inserted into the side formwork positioning groove on the bottom formwork. The reinforcing cage includes multiple vertical main reinforcement bars and circumferential stirrups. The reinforcing cage is installed inside the side formwork, with the lower ends of the vertical main reinforcement bars inserted into the main reinforcement positioning tubes on the bottom formwork. The spacing between the reinforcing cage and the side formwork is set according to the thickness of the concrete cover.

[0006] By using this invention to conduct concrete pouring tests, the effect of air bubble removal in the concrete can be observed, thereby optimizing the concrete mix ratio, improving the quality of the release agent, optimizing the construction vibration process, and ensuring construction quality before concrete construction.

[0009] like Figure 1 , Figure 2As shown, this utility model includes a bottom template 1, side templates 2, and a reinforcing cage 3. The bottom template has multiple main reinforcement positioning tubes 4 arranged vertically according to the spacing of the main reinforcement bars of the reinforcing cage. A ring-shaped side template positioning groove 5 is provided around the main reinforcement positioning tubes. The side template 2 is a cylindrical structure made of transparent acrylic sheet. The bottom of the side template 2 is inserted into the side template positioning groove 5 on the bottom template. The reinforcing cage 3 includes multiple vertical main reinforcement bars and circumferential stirrups. The reinforcing cage is installed inside the side template. The lower ends of the vertical main reinforcement bars of the reinforcing cage are inserted into the main reinforcement positioning tubes 4 on the bottom template. The spacing between the reinforcing cage and the side template is set according to the thickness of the reinforcing cage protective layer.

[0010] The method of using this utility model is as follows:

[0011] Fabricate a steel cage, with the spacing of the main reinforcement bars in the cage simulating the design spacing of the main reinforcement bars in the concrete structure to be poured.

[0012] Install the steel cage onto the bottom formwork;

[0013] Apply release agent to the inner wall of the side formwork, and install sealing strips in the side formwork positioning grooves on the bottom formwork to prevent grout leakage; install the side formwork onto the bottom formwork.

[0014] Pour concrete and conduct test vibrations at different depths and for different times. At the same time, observe the generation and discharge of air bubbles in the concrete and record the effect of air bubble discharge.

[0015] After the concrete reaches the demolding strength, pull the side formwork upwards;

[0016] Observe the appearance quality of the concrete. If the desired effect is not achieved, repeat the test until the desired effect is achieved, and determine the final concrete construction plan.
