Code for Quality Acceptance of Masonry Engineering (GB50203-2002)

5.2.4 For temporary breaks in areas with non-seismic fortification intensity of 6 and 7 degrees, if oblique gaps cannot be left, straight gaps can be left except at corners, but the straight gaps must be made into convex gaps. Stay straight if Rachel should be added, the number of Rachel reinforcement is per 120mm wall thickness 1 φ 6 Rachel reinforcement (2 φ 6 Rachel reinforcement are placed on 120mm wall thickness), and the spacing along the wall height should not exceed 500mm；; The embedding length is not less than 500mm from each side of the indwelling point and not less than1000mm; Areas with seismic fortification intensity of 6 degrees and 7 degrees; The ending should be 90? Hook.
