Assembly type concrete prestressed laminated bottom plate
The invention discloses an assembly type concrete prestress laminated bottom plate. The laminated bottom plate comprises a concrete bottom plate and a truss, wherein longitudinal steel bars parallel to the length direction of the concrete bottom plate are further arranged in the concrete bottom plate, and the truss comprises an upper chord member parallel to the length direction of the concrete bottom plate; first web members and second web members are arranged on the two opposite sides of the upper chord member respectively, top ends of the first web members and the top ends of the second web members are fixedly connected with the upper chord member in a welded mode, and the first web members and the second web members in one set at the opposite positions form a web member unit; a bottom end of the first web member and a bottom end of the second web member are respectively embedded in a concrete bottom plate, and the structure is characterized in that the first web member and the second web member are arranged to be of an inverted-V-shaped structure, and two lower ends of the inverted-V-shaped structure are arranged to be of structures with hooks; the structure with the hook of the first web member and the structure with the hook of the second web member are oppositely arranged in the direction perpendicular to the longitudinal direction, and the longitudinal reinforcing steel bars penetrate through the structures with the hooks and are fixed; U-shaped steel bars or N-shaped steel bars are arranged in the bottom plate, parallel bars of the U-shaped steel bars or the N-shaped steel bars are arranged perpendicular to the length direction of the bottom plate, and connecting flanges are arranged at two ends of the upper chord member; construction efficiency is improved, and the cost is reduced.
本发明公开了一种装配式砼预应力叠合用底板，包括混凝土底板和桁架，所述混凝土底板内还设置有与所述混凝土底板长度方向平行的纵向钢筋，所述桁架包括与所述混凝土底板长度方向平行的上弦杆，和多组分别设置在上弦杆相对两侧的第一腹杆及第二腹杆，所述第一腹杆和所述第二腹杆的顶端与所述上弦杆通过焊接固定连接，所述相对位置一组第一腹杆和第二腹杆构成腹杆单元,所述第一腹杆和所述第二腹杆的底端分别预埋在混凝土底板内，其特征在于：所述第一腹杆和所述第二腹杆设置为Λ形结构，Λ形结构的两个下端设置为带钩结构，所述第一腹杆的带钩结构和所述第二腹杆设置的带钩结构相向垂直于纵向方向设置，所述纵向钢筋从所述带钩结构中穿过并固定；底板内设置有U形钢筋或N形钢筋，且U形钢筋或N形钢筋的平行筋垂直于底板长度方向设置，上弦杆的两端端部设置有连接法兰；具有提高施工效率，降低成本等优点。
