[0001] This utility model relates to the field of prefabricated masonry technology, and in particular to a novel mortar-free self-embedding prefabricated block structure. Background Technology

[0002] With the acceleration of urbanization, masonry structures are also developing towards green and prefabricated directions. Building blocks are semi-finished building materials and are the basic unit blocks that make up masonry components (walls, columns, etc.). The raw materials for blocks are widely available, diverse, locally sourced, and inexpensive. They generally include cement, sand and gravel, natural pumice, tuff, artificial ceramsite, and industrial waste (such as fly ash, coal gangue, and blast furnace slag).

[0003] Traditional masonry construction relies on on-site bricklaying and mortar bonding, resulting in long construction cycles, high labor intensity, and severe environmental pollution, making it difficult to meet the demands of modern industrialized, efficient, and sustainable construction. Existing mortarless masonry construction often enhances the integrity of the masonry by using methods such as drilling and grouting holes in masonry blocks, focusing more on the masonry itself and rarely considering the connection between the masonry structure and the building's structure, such as columns and beams, and the connection methods therein. However, the industry requires a construction method that allows for rapid assembly and convenient replacement of masonry blocks, as well as a good connection method between the masonry and the structure to improve its integrity and seismic resistance.
