[0002] Prefabricated components are a type of building structural panels made of concrete and steel materials. They are called prefabricated components because they have been completed before on-site installation. Common prefabricated building components are mostly in the form of plates and beams. In the later stages of construction, prefabricated components play a major role in sound insulation and noise reduction, so a noise reduction structure is needed.

[0003] For example, application number: 202120598828.7 involves a prefabricated component with noise reduction effect, including a triangular fixed hook, a prefabricated concrete wall panel, fixed steel bars and a reserved empty groove. The interior of the prefabricated concrete wall panel is fixedly connected with a fixed steel bar, and the interior of the fixed steel bar is provided with a connection reinforcement structure. The connection reinforcement structure includes a reinforcing steel bar block, transverse reinforcing ribs, vertical reinforcing ribs and an inner cavity groove. The inner cavity groove is fixedly connected to the interior of the fixed steel bar, the reinforcing steel bar block is fixedly connected to the interior of the inner cavity groove, and the transverse reinforcing ribs are fixedly connected to both sides of the reinforcing steel bar block.

[0004] Based on the findings in the prior art, existing prefabricated components usually use a solidified concrete layer in combination with decorative panels for sound insulation and noise reduction. However, since the concrete is in a solid structure after solidification, it is easy to generate noise after being vibrated. This makes it have a noise reduction effect during normal use, but it is also easy to become a noise source, resulting in a low overall noise reduction effect. Utility Model Content
