Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete test piece forming, and particularly relates to a vibrating device for concrete test piece forming. BACKGROUND

[0002] In some small construction sites, the quality of concrete usually needs to be detected before construction to ensure the overall safety and stability of the project. A common detection method is to make concrete test blocks of different sizes and perform vibrating operation therein. The vibrating operation can effectively remove air bubbles and voids in the concrete, improve the compactness of the test block, and thus enhance the strength and forming effect thereof. The concrete vibrating devices on the market are mainly divided into two types: vibrating tables and vibrating machines, which have various specifications and adapt to the needs of different construction scenes. In actual application, handheld vibrating rods and small vibrating platforms are more common. Construction personnel can flexibly adjust the use mode according to the on-site environment.

[0003] However, when the handheld vibrating rod vibrates the concrete in the mold, the strong vibration easily causes the concrete to flow, resulting in overflow from the top of the mold. After the vibrating is completed, the surface usually needs to be manually smoothed to ensure that the test block meets the subsequent detection standards, which reduces the work efficiency to a certain extent. The vibrating platform has a single function. For example, when the vibrating platform vibrates the concrete added with a net-shaped fiber, the net-shaped fiber cannot be uniformly dispersed, and the vibrating mode cannot be automatically adjusted according to different types and sizes of test blocks, so that efficient and accurate vibrating effect cannot be achieved. During the vibrating process of the vibrating platform, the stability of the mold is insufficient, which easily causes the mold to shake. Especially when there is a large gap between the mold and the table surface, the mold is more likely to be displaced, which affects the vibrating quality. Not only does this reduce the construction efficiency, but also it may affect the forming effect of the concrete test block and the strength detection result, which is difficult to meet the requirements of high-standard construction.

When the test piece mold needs to be taken out from the fixed table 21, the bolt 25 is disassembled from the second L-shaped block 24, the second L-shaped block 24 is slid away from the test piece mold, and then the first L-shaped block 23 is pulled out from the fixed table 21. Therefore, the fixing assembly is released to fix the test piece mold, and then the test piece mold is taken off from the fixed table 21. The operation is simple and convenient. After the concrete in the test piece mold is solidified, the concrete is taken out from the test piece mold, and then the concrete is tested.
