1　框架梁和柱有一侧面齐平过去结构上有个要求 ,即梁宽比柱宽至少小5 0ｍｍ ,以保证梁钢筋必须穿入柱钢筋的内侧 ,现在建筑设计在很多情况下要求梁与柱的外侧齐平 ,此时梁外侧钢筋的混凝土保护层厚度将等于柱筋保护层厚度加柱纵筋的直径 ,一般可达 5 0ｍｍ左右。建议可采取如 1 The frame beam and the column have a side flush. In the past, there was a requirement in the structure that the width of the beam was at least 50 mm smaller than the column width to ensure that the beam reinforcement must penetrate into the inside of the column reinforcement. Now the building design requires the outside of the beam and the column in many cases. At the time of flushing, the thickness of the concrete protective layer on the outer side of the beam will be equal to the thickness of the column protective layer plus the length of the column longitudinal bar, which is generally about 50 mm. Recommendations can be taken as
