Description

Technical Field

[0002] In recent years, my country's construction industry and concrete have experienced rapid development, particularly in bridge engineering and prefabricated component engineering. The assembly rate of buildings in my country has increased year by year, along with the demand for special-shaped structures and precast concrete components. Simultaneously, an increasing number of projects are requiring high-quality exposed concrete, raising the bar for high surface quality. Concrete release agents are sprayed or applied to the inner wall of concrete component formwork to provide lubrication and insulation, allowing the concrete to separate smoothly from the formwork during demolding, facilitating the concrete's release and maintaining a smooth surface.

[0003] There are many types of release agents in the construction industry. In addition to pure oil release agents, the commonly used new release agents mainly include emulsified oils and organic polymers, which have different performances. For formworks of different materials and concrete with different construction conditions and finishing requirements, appropriate release agents must be selected to achieve good results, reduce or even avoid concrete honeycomb, pores, color difference and other appearance defects, and improve the surface quality of concrete.

[0004] The traditional evaluation method is mainly to apply the release agent to the surface of the concrete forming mold, and then observe the surface porosity after forming, hardening and demolding. This method has a long time cycle and low efficiency. Therefore, it is very necessary to develop a device for testing the defoaming performance of concrete release agents, which can intuitively and quickly measure the defoaming effect of concrete release agents on the concrete surface to meet the future development needs of plain concrete.

[0029] Reference Figure 1The embodiment of the utility model provides a rapid testing device for the defoaming performance of a concrete release agent, which includes a base 1, a transparent container 2 and a vibrator.

[0030] A transparent container 2 is placed on a pedestal 1, and the top surface of the transparent container 2 has an opening. A vibrator is placed on the pedestal 1, and a vibrating rod 3 of the vibrator is fixed to the pedestal 1 via a fixing member 4, and the vibrating rod 3 can extend into the transparent container 2 through the opening.

[0031] The utility model is used to evaluate the defoaming performance of a concrete release agent. During use, the concrete release agent is applied to the inner surface of a transparent container 2. Concrete is then poured into the transparent container 2. A vibrating rod 3 is inserted into the transparent container 2, preferably with the bottom of the vibrating rod 3 not contacting the bottom surface of the transparent container 2. Vibration of the vibrating rod 3 is used to vibrate the concrete. The user can directly observe the changes in bubbles in the concrete on the surface of the transparent container 2 to evaluate the defoaming performance of the concrete release agent.

[0032] In some embodiments, the base 1 is an iron base.

[0033] In some embodiments, the fixing member 4 is made of iron.

[0034] In some embodiments, the vibrator is an electric concrete vibrator driven by a motor 5 .

[0035] The electric concrete vibrator can directly adopt the existing technology.

[0036] In some embodiments, the fixing member 4 is an inverted L-shaped structure, the vertical section of the fixing member 4 is fixed on the base 1, and the horizontal section of the fixing member 4 clamps the vibrating rod 3 through the clamping member 6.

[0037] The clamping member can be any clamping member in the prior art that can clamp the rod, for example, a clamp, a throat clamp or a U-shaped clamp.

[0038] In some embodiments, the horizontal section of the fixing member 4 can slide on the vertical section of the fixing member 4 in the up-down direction and can be locked, so that the distance between the bottom of the vibrating rod 3 and the inner bottom surface of the transparent container 2 can be adjusted.

[0039] Before use, the vibrating rod 3 can be adjusted to a height away from the transparent container 2, and the transparent container 2 can be easily removed from the base 1 to apply a release agent and inject concrete.

[0040] In some embodiments, the vertical section of the fixing member 4 is a telescopic section that can be extended and locked in the vertical direction, so that the distance between the bottom of the vibrating rod 3 and the inner bottom surface of the transparent container 2 can be adjusted.

[0041] In some embodiments, the transparent container 2 is made of acrylic material.

[0042] Of course, the transparent container 2 may also be made of other materials with transparency.

[0043] In some embodiments, the top surface of the transparent container 2 is an open structure to facilitate the application of release agent and the injection of concrete.

[0044] In some embodiments, the transparent container 2 is a polyhedral structure with a flat bottom and at least one flat side.

[0045] The transparent container 2 with a flat bottom surface can be stably placed on the base 1 .

[0046] Since concrete is usually poured on a flat surface, the transparent container 2 with at least one flat side can simulate the actual scene and directly observe the changes of concrete bubbles on the flat side surface.

[0047] In some embodiments, the transparent container 2 is a curved polyhedron structure with a flat bottom, at least one flat side surface, and at least another curved side surface.

[0048] In order to be applicable to the scenario where the concrete pouring surface is a curved surface structure, one side surface of the transparent container 2 in this embodiment is a curved surface structure to simulate the curved surface scene for testing.

[0049] For example, the transparent container 2 can be cut vertically on the side of a cylinder to form a flat cross-section, which satisfies the curved polyhedron structure of the transparent container 2 of the present invention. Of course, it is also possible to cut vertically on the side of a cylinder to form two symmetrical cross-sections to form a flat structure, in which case the transparent container 2 has a curved hexahedron structure with two flat sides and two curved sides.

[0050] In some embodiments, the transparent container 2 is a transparent container 2 with a rectangular parallelepiped structure.

[0051] In some embodiments, the length, width and height of the transparent container 2 are all 10 cm to 30 cm, preferably 20 cm.

[0052] The length of the vibrating rod 3 is 20 cm to 40 cm, preferably 30 cm.

[0053] The area of the pedestal 1 is larger than the bottom area of the transparent container 2. The length and width of the pedestal 1 are both 60 cm, for example.

[0054] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the present invention shall be protected within the scope of the appended claims.
