砌筑（masonry） First, the composition of masonry works (Book map) Space: refers to the use of permeable wall wall common clay brick masonry, empty flower part wall thickness more than 120 or 240. Independent air upper top lower masonry wall, solid wall. Porous brick walls - porous bricks are usually fired from clay, shale and coal gangue. They are porous and small, with pores larger than 15%. The wall has good thermal performance and light weight. It is used as a load-bearing wall (below 6 floors). Hollow brick walls - hollow bricks, usually fired from clay, shale, coal gangue, etc., with fewer pores and larger pores, greater than 35%, and are mostly 4 holes and 6 holes. They are used as non load bearing walls (partitions or infilled walls of frame structures). The main part of the project, two brick: ? Foundation (A3-1) and solid masonry walls (A3-2~4) - porous brick wall (A3-5~8), hollow brick wall (A3-9~12), (A3-13), empty wall infilled masonry wall (A3-14~15), (A3-16~20) Brick column (A3-21~22) - reinforced brick lintel (A3-23) Basement wall (A3-24~26) Other (A3-27~39) (1) division of foundations and walls: 1. When the same material is used in the foundation and the wall, the interior floor shall be designed as the boundary line, and the wall shall be as follows, as shown above 2. When using different materials for foundation and wall, such as two kinds of materials are separated from the interior design floor more than + 30cm, with interior design floor as the dividing line, as shown. 3. When the foundation and wall are made of different materials, the dividing line is within the height of 30cm from the interior design floor to the boundary of different materials, as shown. 4. Masonry walls are designed with outdoor floors as the boundary, and the following as the foundation. Brick column regardless of the shaft and column, the engineering quantity after the merger, according to the brick project calculation. (brick column on both sides of the wall prominent, such
