Angle steel truss prestressed concrete laminated slab
The invention discloses an angle steel truss prestressed concrete laminated slab. The angle steel truss prestressed concrete laminated slab comprises a prefabricated bottom plate and a plurality of trusses arranged in parallel at intervals, prestressed tendons and structural distribution steel bars are arranged in the prefabricated bottom plate, each truss comprises angle steel, a first web member steel bar and a second web member steel bar, the lower ends of the first web member steel bars are pre-buried in the prefabricated bottom plate, the ends of the first web member steel bars extend to the position below the prestressed tendons, the upper ends of the first web member steel bars are welded to one sides of the angle steels, the lower ends of the second web member steel bars are pre-buried in the prefabricated bottom plate, the ends of the second web member steel bars extend to the position below the prestressed tendons, the upper ends of the second web member steel bars are welded to the other sides of the angle steels, and an opening of each angle steel is upward. According to the angle steel truss prestressed concrete laminated slab, original steel bar trusses and round steel pipe trusses are replaced with the angle steel trusses, the overall strength and rigidity are improved by combining the prefabricated bottom plate, the production process is simplified, the production and transportation efficiency is improved, the production and transportation cost is reduced, and meanwhile the construction difficulty is reduced.
本发明公开了一种角钢桁架预应力混凝土叠合板，包括预制底板和多个平行间隔设置的桁架，所述预制底板内设有预应力筋和构造分布钢筋，所述桁架包括角钢，第一腹杆钢筋和第二腹杆钢筋，所述第一腹杆钢筋下端预埋在预制底板内，其端部延伸至预应力筋下方，第一腹杆钢筋上端与角钢的一侧焊接，所述第二腹杆钢筋下端预埋在预制底板内，其端部延伸至预应力筋下方，第二腹杆钢筋上端与角钢的另一侧焊接，所述角钢开口向上。本发明所揭示的一种角钢桁架预应力混凝土叠合板，采用角钢桁架替代原有的钢筋桁架及圆钢管桁架，结合预制底板提高了整体的强度和刚度，简化了生产工艺，提高了生产和运输效率，降低了生产和运输成本，同时降低了施工难度。
