Problems solved by technology

[0003] In the existing construction method, the fixtures used in hoisting are relatively complicated, and the hoisting efficiency is too low. At the same time, due to the influence of wind force, there will be shaking and collision with other objects during the hoisting process.

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, ...

Abstract

The invention discloses a construction method of PK prestressed concrete overlapping slabs. The construction method comprises the following steps: S1, according to the requirements of a design drawing, preparing corresponding PK slabs, conveying to a construction site, and stacking by batches; S2, according to designed locations of the PK slabs in the drawing, setting up support frames with adjustable height at the corresponding locations, so as to press the PK slabs onto transverse rods in the support frames; S3, enabling lifting equipment to lift the PK slabs to the corresponding locations, and simultaneously paving the PK slabs one by one until fully paving; S4, according to the design requirements of the drawing, reserving a water and electricity pipeline mounting hole in the corresponding PK slab; S5, sealing at a connecting part of each PK slab and a beam and column formwork; S6, arranging a reinforcing bar and a pipeline on each PK slab; S7, casting concrete on each PK slab; S8, detaching the support frames and the beam-column formwork set up in step 2. The construction method of the PK prestressed concrete overlapping slabs has the advantages that the PK slabs are lifted by a self-made lifting tool, the lifting time is shortened, and the lifting procedure is simplified.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for PK prestressed concrete laminated slabs. Background technique [0002] PK prestressed concrete laminated slab is referred to as PK slab, which is often used in the laying of floors. It uses concrete prefabricated thin slabs with ribs as the bottom plate, and oval holes are reserved on the ribs, and transverse non-prestressed steel bars are inserted in the holes, and then laminated concrete is poured to form an overall two-way stressed floor. When laying the floor slabs, it is necessary to hoist the PK slabs one by one to the corresponding position, then lay them according to the requirements of the drawings, and then pour the laid PK slabs. [0003] In the existing construction method, the jigs used during hoisting are relatively complicated, and the hoisting efficiency is too low. At the same time, due to the influence of wind force, during the hoi...
