Superposed embedded column provided with vertical stress reinforcing steel bar of large diameter edge member in cavity and prefabricated wall
The invention relates to a superposed embedded column provided with a vertical stress reinforcing steel bar of a large diameter edge member in a cavity and a prefabricated wall. A vertical structure reinforcing steel bar of a small diameter edge member is only configured in a prefabricated concrete wallboard to form an embedded column reinforcement cage with a stirrup and a tie bar of the edge member, and the upper and lower ends of the vertical structure reinforcing steel bar of the edge member do not extend outside the prefabricated concrete wallboard and do not take part in structural stress calculation; a single-row large diameter vertical reinforcing steel bar is configured in the cavity as a vertical stress reinforcing steel bar of the edge member in the cavity, takes part in structural stress calculation, and the vertical stress reinforcing steel bars of upper and lower edge members are connected by a reinforcing steel bar joint in the cavity, so that the stress is reliable, andthe use level of the vertical reinforcing steel bars of a wall is not increased. Concrete is post-poured in a cast-in-place cavity to form the superposed embedded column. The structural production stage can prevent the vertical reinforcing steel bar of the edge member from interfering the prefabricated wall, so that it is convenient to produce the prefabricated wall. A field mounting stage can prevent double-row vertical connecting reinforcing steel bars in the superposed embedded column from affecting the mounting precision of the prefabricated wall, so that it is favorable to improve the mounting efficiency and the mounting precision of the prefabricated wall.
一种空腔内配置大直径边缘构件竖向受力钢筋的叠合暗柱及预制墙，在预制混凝土壁板中仅配置小直径的边缘构件竖向构造钢筋与边缘构件箍筋、拉筋形成暗柱钢筋骨架，边缘构件竖向构造钢筋上下端均不伸出预制混凝土壁板、不参与结构受力计算；在空腔内配置单排大直径竖向钢筋作为边缘构件竖向受力钢筋，参与结构受力计算，上下层边缘构件竖向受力钢筋在空腔内采用钢筋接头连接，受力可靠，且不增加墙体竖向钢筋用量，现场浇筑空腔内后浇混凝土形成叠合暗柱。上述构造生产阶段可避免边缘构件竖向钢筋对预制墙产生干扰，便于预制墙生产；现场安装阶段可避免叠合暗柱内双排竖向连接钢筋对预制墙安装精度的影响，有助于提高预制墙安装效率和安装精度。
