Description

Technical Field

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

[0002] In my country, to test whether the concrete strength is qualified, it is necessary to determine it through the compressive strength of the concrete test block. At this time, it is necessary to make a concrete test block. When making the concrete strength test block, the concrete bubbles in the concrete test block must be discharged by vibration, and the concrete in the test block must be vibrated, so that the strength of the concrete can be tested accurately. Therefore, a concrete test block forming vibration device is needed. At present, there are three main types of concrete test block forming vibration tables used in laboratories. One type is composed of a table top, a table bottom frame, a vibrator spring, an eccentric vibrator and other components. When in use, the test block filled with concrete is placed on the table top, and the equipment is started to vibrate the concrete test block. However, during the vibration process, due to the lack of restraint, the test block on the table top will jump, which is difficult to control and prone to the risk of falling. Even if the test personnel hold the test block by hand, it will not have much effect. In addition, the residual concrete on the table top generally needs to be cleaned manually, which is relatively laborious. Therefore, this application document provides a concrete test block vibration device to solve the above problems. Utility Model Content
