Embodiment
[0025] The PK prestressed concrete laminated slab construction method provided by the present embodiment includes the following steps: S1, prepare corresponding PK slabs 4 according to the requirements of the design drawings, and transport them to the construction site for stacking in batches; S2, design the PK slabs according to the drawings 4. Set up a height-adjustable support frame at the corresponding position to ensure that the PK boards 4 are pressed on the crossbars in the support frame; Lay until it is fully paved; S4, according to the design requirements of the drawings, reserve holes for installing water and electricity pipelines on the corresponding PK board 4; S5, perform sealing treatment at the junction of the PK board 4 and the beam-column formwork; S6, on the PK board 4 Arranging steel bars and pipelines; S7, pouring concrete on the PK slab 4; S8, removing the support frame and beam-column formwork erected in step 2.
[0026] Further, when stacking PK boards, ...
