Description

Technical Field

[0002] As my country's building energy conservation rate has increased to 75%, external wall insulation technology needs to be further developed. The traditional thin plaster external wall insulation system needs to be poured, demolded, and chiseled before insulation construction can be carried out. There is only a weak anti-cracking protective layer on the outside, so there are weaknesses such as long construction period, poor fire resistance, short life, complex construction, and high cost. Its own insulation performance is not good, and it is necessary to install an insulation layer in the later construction. In addition, formwork needs to be set up on both sides of the wall during construction. When the concrete solidifies, the formwork on both sides needs to be removed. The operation is cumbersome and seriously slows down the construction progress.

[0003] Concrete composite wall panels are a good structural form that combines prefabrication and cast-in-place concrete. The prefabricated prestressed thin panels and cast-in-place concrete layers are combined into a whole and work together.
