AI Technical Summary

Technical Problem

Traditional autoclaved aerated concrete (AAC) blocks are mostly solid structures, resulting in a large overall weight, which increases the load on the building foundation. This may require strengthening the foundation and load-bearing structure, increasing costs. Furthermore, they require more raw materials to produce, which is not in line with the trend of green building.

Method used

Design an autoclaved aerated concrete block with a cavity and lightweight porous structure, internal sound insulation cotton and foam columns, external reinforcing rings and horizontal crossbars, and stable connection through assembly grooves and protruding plates, reducing weight and enhancing structural strength.

Benefits of technology

Significantly reducing the weight of masonry blocks, reducing material usage, reducing pressure on the foundation and load-bearing structure, improving installation efficiency and seismic performance, reducing labor costs, and meeting green building requirements.

Abstract

This utility model discloses an autoclaved aerated concrete (AAC) block, comprising a main body. An assembly groove is formed on one side of the main body, and an assembly protrusion that mates with the assembly groove is fixedly installed on the other side. A cavity is formed in the center of the main body. This utility model relates to the field of autoclaved aerated concrete (AAC) block technology. This AAC block, through the cooperation between the cavity and lightweight pores, can significantly reduce the overall weight of the block, lessening the burden on workers during installation, reducing material consumption during production, reducing pressure on the foundation and load-bearing structure, making handling and construction easier, improving efficiency, and reducing labor costs. The cooperation of reinforcing rings and foam columns provides support and reinforcement to the cavity and lightweight pores, improving the overall strength of the block, reducing the risk of cracking, and enhancing seismic performance.
