Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibration, in particular to a concrete vibration device. Background Art

[0002] Before pouring concrete components, test blocks need to be tested. This is mainly used to test and evaluate the physical properties of concrete, such as strength and durability, to ensure that the quality of the concrete meets the requirements of engineering design and construction, thereby ensuring the safety and durability of the building. However, a vibrating device is needed to remove bubbles from the concrete, make the concrete densely combined, and eliminate phenomena such as honeycombed surface of the concrete, so as to improve its strength and ensure the quality of concrete components.

[0003] At present, some of the methods used can only vibrate the concrete in a single mold, but there are multiple test blocks required for testing, and the staff can only vibrate them one by one. This method increases the time required for test block testing and increases the workload of the staff. At the same time, after the air in the concrete in the mold is removed, the staff is required to manually smooth the concrete that exceeds the mold to prevent the bulge from affecting the test results of the test block. This method further increases the workload of the staff and prolongs the waiting time required for the next step of the test. Utility Model Content
