Full-prefabricated assembly type steel-concrete composite floor system and design calculation method
The invention discloses a full-prefabricated assembly type steel-concrete composite floor system and a design calculation method. The floor system comprises prefabricated concrete floors (1), an H-shaped steel beam (2), beam-slab UHPC tenon-and-mortise connection nodes (3) and slab-slab UHPC tenon-and-mortise connection nodes (4), wherein shear-resistant slotted holes (11) are formed in the two sides of each prefabricated concrete floor (1) in the slab thickness direction; stud connecting pieces (21) are welded on the upper flange of the H-shaped steel beam (2); the two prefabricated concrete floors (1) are connected with the H-shaped steel beam (2) through the beam-slab UHPC tenon-and-mortise connection nodes (3); and every two adjacent prefabricated concrete floors (1) are connected through the plate-plate UHPC tenon-and-mortise connection nodes (4). According to the design provided by the invention, the ultra-high performance concrete UHPC is adopted for connection between the prefabricated concrete floors and the H-shaped steel beam and connection between the prefabricated concrete floors, and the fabricated floor system has the advantages of simple structure, reliable performance, convenience and rapidness in construction, green and environmental protection, and the like.
本发明公开了一种全预制装配式钢‑混组合楼盖体系及设计计算方法，该楼盖体系包括预制混凝土楼板（1）、H型钢梁（2）、梁板UHPC榫卯连接节点（3）和板板UHPC榫卯连接节点（4），其中：预制混凝土楼板（1）的两侧沿板厚方向开有抗剪槽孔（11）；H型钢梁（2）上翼缘上焊接有栓钉连接件（21）；两预制混凝土楼板（1）与H型钢梁（2）之间采用梁板UHPC榫卯连接节点（3）连接；相邻两预制混凝土楼板（1）之间采用板板UHPC榫卯连接节点（4）连接。本发明设计采用超高性能混凝土UHPC进行预制混凝土楼板与H型钢梁间及预制混凝土楼板间的连接，该装配式楼盖体系具有构造简单、性能可靠、施工方便快捷、绿色环保等优势。
