Truss-rib-free PC laminated slab and construction method

The invention discloses a truss-rib-free PC laminated slab and a construction method, and solves the problems that an existing laminated slab adopts steel bars, mounting ribs and supporting ribs to be laminated and fixed, so that building pipelines are very inconvenient to arrange in gaps between the steel bars, the mounting ribs and the supporting ribs and the laminated slab, pipeline arrangement before secondary pouring is not facilitated, and the construction difficulty is increased. Comprising a laminated slab body, and the laminated slab body comprises a one-way laminated slab, fixed profile steel and adjustable profile steel; the profile steel adjusting part is used for adjusting the position of the adjustable profile steel; the self-adaptive connecting assembly is arranged on the side wall of the one-way laminated slab, and the self-adaptive connecting assembly is used for fixing the one-way laminated slab; according to the truss-rib-free composite system, the composite plate body is arranged, the comp
