Full-prefabricated concrete floor slab connecting structure and design calculation method
The invention discloses a full-prefabricated concrete floor slab connecting structure and a design calculation method. The connecting structure comprises prefabricated concrete floor slabs (1) on the two sides, a rear steel bar frame (2), a rear penetrating longitudinal bar (3) and post-poured concrete (4); longitudinal through grooves (11) and a plurality of vertical through grooves (12) are formed in the side faces of the connecting sides of the prefabricated concrete floor slabs (1); the rear steel bar frame (2) is arranged in the vertical through grooves (12) of the floor slabs on the two sides in a centered mode; the rear penetrating longitudinal bar (3) is arranged in the rear steel bar frame (2) in a penetrating mode; and the post-poured concrete (4) is poured in the longitudinal through grooves (11) and the plurality of vertical through grooves (12). The in-slab shear resistance, flexural rigidity and bearing capacity of the full-prefabricated floor slabs can be remarkably improved, deformation coordination of slab joints during vertical load bearing is guaranteed, and the using performance similar to that of an overall cast-in-place floor system can be achieved. The full-prefabricated concrete floor slab connecting structure is reliable in performance, simple in structure, rapid in construction and environmentally friendly.
本发明公开了一种全预制混凝土楼板连接构造及设计计算方法，该连接构造包括两侧的预制混凝土楼板（1）、后置钢筋架（2）、后置贯穿纵筋（3）以及后浇混凝土（4），预制混凝土楼板（1）在连接侧的侧面开有纵向贯通槽（11）和多个竖向贯通槽（12）；后置钢筋架（2）居中设置在两侧楼板的竖向贯通槽（12）内；后置贯穿纵筋（3）穿设于后置钢筋架（2）中；后浇混凝土（4）浇筑在纵向贯通槽（11）和多个竖向贯通槽（12）中。本发明可显著提升全预制楼板面内抗剪、抗弯刚度和承载能力，并保证承受竖向荷载时板缝处的变形协调，可达到近似整体现浇楼盖的使用性能。本发明性能可靠、构造简单、施工快速、绿色环保。
