Description

Technical Field

[0001] The invention relates to building construction, in particular to a construction method for combining an ALC plate with a concrete block. Background Art

[0002] At present, in the construction of building projects, autoclaved aerated concrete panels (ALC panels for short) have been widely promoted and applied due to their advantages of environmental protection, fire prevention, sound insulation, heat insulation, strong hanging force, light weight and economy, good integrity, strong assembly ability, and greatly reducing the number of construction personnel and time. However, since ALC panels are reinforced autoclaved aerated concrete slats with good integrity, their construction is difficult in areas with more openings and the quality control effect is poor. Pre-opening and post-opening openings will cause material waste, and a large number of metal accessories will be used, making construction quality control difficult, and easily causing damage to the panels, with high repair or replacement costs. Therefore, in areas with more pipelines, the practicality of ALC panels is not high. How to make improvements is the key to improving the construction quality of the filling wall.

[0003] Compared with ALC boards, autoclaved aerated concrete blocks are more flexible, with more mature construction hole retention and post-opening, and the construction quality is easy to control, but they do not have the advantages of ALC boards in terms of convenience and speed of construction and reducing the number of construction personnel. Therefore, how to combine the two types of infill wall construction materials and processes to form an efficient and high-quality construction method is the key to secondary structure construction. Summary of the invention
