This utility model discloses a prefabricated earthquake-resistant aerated concrete block, including a block mechanism and a fixing mechanism assembled inside the block mechanism. The block mechanism includes a block body, an
assembly protrusion plate is fixedly installed on one side of the block mechanism, and an
assembly groove for cooperating with the
assembly protrusion plate is opened on the other side of the block mechanism. A fixing hole is opened at the central position inside the block body. This utility model relates to the field of aerated concrete block technology. This prefabricated earthquake-resistant aerated concrete block, through the cooperation between the block body, the fixing hole, and the fixing rod, can tighten the block from top to bottom, improving the integrity of the block during assembly and avoiding or reducing the possibility of the block breaking at the joint due to vibration during use. Through the cooperation of the mounting slot and the mounting plate, it is convenient for workers to quickly install the block body on the outside of the fixing rod, increasing the convenience and efficiency of installation.
