Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a precast concrete building steel-concrete interior wall panel. Background Technique

[0002] With the rapid development of the construction industry, prefabricated buildings are gradually winning wide attention in the industry due to their advantages of fast construction speed, energy conservation, environmental protection, and reliable quality. Among many prefabricated building technologies, the design and construction of concrete interior wall panels are particularly crucial, which directly affect the overall performance and user experience of buildings. However, there are some obvious defects in the design of traditional interior wall panels, such as poor sound insulation effect, complex installation process, and insufficiently firm connection, which to a certain extent affect the use experience and functionality of buildings.

[0003] The patent with the publication number CN218437957U discloses a precast ultra-low energy consumption concrete building steel-concrete interior wall panel, which is formed by an interior wall panel, an exterior wall panel, a steel frame and a thermal insulation board between the exterior wall panel and the interior wall panel.
