Recycled concrete laminated slab containing prestressed FRP rib bundle fibers and manufacturing method thereof
The invention relates to a recycled concrete laminated slab containing prestressed FRP rib bundle fibers and a manufacturing method thereof. The recycled concrete laminated slab comprises a concrete lower slab body; a transversely and longitudinally staggered steel reinforcement framework is erected in the concrete lower slab body; a plurality of inverted V-shaped convex ribs are uniformly distributed at the upper end of the steel reinforcement framework; V-shaped openings of the convex ribs face downwards; the end parts of the convex ribs are fixedly connected with the steel reinforcement framework; the top ends of the convex ribs protrude out of the concrete lower slab body and are combined with a concrete upper slab body poured at the upper end of the concrete lower slab body; a plurality of pre-embedded pipes arranged in parallel in the horizontal direction are embedded in the concrete lower slab body; and FRP rib bundles are inserted in pre-embedded pipe holes. According to the recycled concrete laminated slab containing prestressed FRP rib bundle fibers and the manufacturing method thereof, the connection between the concrete upper slab body and the concrete lower slab body is reinforced, coordinated deformation of concrete at a connecting position is guaranteed, and the adverse effect caused by insufficient integrity of a prefabricated concrete laminated slab is prevented.
本发明涉及一种含预应力FRP筋束纤维再生混凝土叠合板及其制作方法，包括混凝土下板体，该混凝土下板体内架设有横纵交错的钢筋骨架，钢筋骨架上端均布有若干呈倒V型的凸筋，所述凸筋V口朝下并于端部固连在钢筋骨架上，凸筋顶端凸出混凝土下板体并与浇筑于混凝土下板体上端的混凝土上板体结合，所述混凝土下板体内预埋有若干沿水平方向平行设置的预埋管，所述预埋管孔内插设有FRP筋束，该混凝土叠合板加强了上、下混凝土板体间的连接，保证连接处混凝土的协调变形，防止预制混凝土叠合板的整体性不足所带来的不利影响。
