Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically a small concrete precast component vibration device. Background Technology

[0002] During the production of precast components, the concrete needs to be vibrated during pouring to prevent defects such as air holes from appearing on the surface of the components after demolding. Vibrators are used to vibrate the components. The concrete precast component vibration device is a machine used for mechanized compaction of precast concrete components. Through vibration, the internal particles of the concrete are rearranged, the gaps between the aggregates are filled with mortar, and air bubbles are squeezed out, thereby achieving the compaction effect and improving the quality of the concrete components.

[0003] For smaller precast components or components with densely spaced reinforcing bars, conventional vibrators cannot penetrate deep into the smaller structural dimensions to effectively vibrate the internal concrete, resulting in unsatisfactory vibration effects. This can easily lead to voids or the mortar failing to coat the coarse aggregate due to improper vibration, resulting in noticeable visual defects. To address these issues, this invention provides a small-scale precast concrete component vibration device. Utility Model Content
