Why is the brick at the top of the wall inclined?

The top brick in the infilled wall should be laid obliquely for the following reasons: 1. In order to make the top of the wall more compact and not easy to crack after plastering, oblique laying can better squeeze the gap with the bottom of the beam and slab. 2. From the construction point of view, 45-60 degree masonry is more convenient for construction. 3. It belongs to the specification requirements: Code for Acceptance of Construction Quality of Masonry Structure Engineering (GB 50203-20119.1.9). Filled wall masonry should be carried out after the inspection batch of load-bearing main structure is qualified. The construction of the gap between the infilled wall and the load-bearing main structure shall be carried out after the infilled wall is laid 14d. 4. To adapt to the deformation of the frame structure: when the frame beam is deformed due to stress, its deformed part will not cause the compression failure of the masonry wall; 5. Beneficial earthquake resistance: Because the masonry wall and the top beam are not rigidly connected, when horizontal seismic waves are generated, the masonry wall will not swing with the frame, ensuring that the influence of the earthquake on the wall can be reduced or partially eliminated.
