Description

Technical Field

[0001] This utility model relates to the fields of building assembly and thermal insulation technology, and in particular to a hollow aerated concrete panel with a thermal insulation layer. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels, with their superior lightweight properties and minimal deformation capacity, coupled with significant thermal insulation effects, have gained widespread recognition and application in the domestic construction industry. These panels not only reduce the overall weight of buildings but also greatly improve their energy efficiency, making a significant contribution to energy conservation and emission reduction. However, as society's standards for thermal insulation and energy conservation continue to rise, traditional AAC panels, relying on a single material, are gradually showing their limitations and are struggling to meet increasingly stringent requirements.

[0003] To overcome this challenge, the industry has begun exploring the composite application of autoclaved aerated concrete (AAC) panels with organic insulation materials, which is considered an effective way to improve panel performance and achieve high efficiency. Specifically, injecting polyurethane or other foaming materials into the internal cavities of AAC panels to form insulation boards constitutes a highly efficient and economical insulation solution. Polyurethane foam, with its excellent insulation properties and closed-cell structure, effectively enhances the overall thermal insulation capacity of the panel, demonstrating the enormous potential of this composite material in the field of insulation.

[0004] However, in practical applications, this type of hollow-structure panel also faces challenges in structural safety. To ensure the stability and load-bearing capacity of the panel, reinforcing ribs are often added around the cavity to resist deformation and damage under external forces. However, the addition of reinforcing ribs undoubtedly occupies space originally intended for insulation material, thus negatively impacting the insulation effect. Especially with the continuous improvement of insulation and energy-saving standards, the thickness of the hollow insulation board often needs to be increased to achieve the ideal insulation effect. However, excessively thick exterior wall panels not only increase material costs but may also exceed design limits, failing to meet the requirements of architectural aesthetics and economy.
