在工程监理中发现,有的设计单位的通用图对多层砖房构造柱底端主筋弯出长度交待不清,导致施工中锚固长度不能满足要求。构造柱的最小截面尺寸一般为240mm×180 mm,混凝土的强度等级不低于C15。纵筋多采用412,角柱和7度设防地区
Found in the project supervision, and some design units of the common map for multi-story brick structure at the bottom of the main bar bending length confused account, resulting in the construction of the anchor length can not meet the requirements. Construction of the minimum cross-sectional column size is generally 240mm × 180mm, concrete strength level of not less than C15. Longitudinal tendon to use more than 412, corner posts and seven degrees fortified areas
