摘　　要：我国自推行钢筋混凝土结构平面表示法后,许多钢筋绑扎没有详图,各地作法也不够统一。例如主梁与次梁相交节点的配筋,三根梁交于一点的配筋,井式楼盖各梁相交处的配筋的排列,板中配筋负弯矩筋直钩长度的确定,梁内纵向受力钢筋排距尺寸,现浇楼板中板在梁上负弯矩筋的支撑等问题,均应对习惯作法进行改进,使之适应目前我国高层建筑的发展。Since reinforced concrete structure ichnography was put into effect,there have not been enough detailed drawings for bond of concrete so that different criteria For reinforcement of intersecting node between main beam and secondary beam,the reinforcement of three beams in one joint,the reinforcement arrangement of beam connections on caission floor,the determination of hook length of negative bent bar,the arrangement dimension of longitudinal stress reinforcing steel bar,negative bent bar bracing of cast-in-place floor etc.have been adopted individually.It is necessary that improvement on the exiting practices should be made to fit for the development of high-rise building in China.

关 键 词：主筋 纵向受力 负弯矩筋
