Further setting the following steps: the light weight layer is made of polystyrene foam plates.

Through adopting above-mentioned technical scheme, protect prefabricated floor overall structure, prolong the building life-span, and have the thermal-insulated effect of heat preservation, reduced the pressure that the structural deformation that leads to because temperature variation produced, make overall structure more stable.

Further setting the following steps: and a plurality of concave parts are arranged at intervals at two ends of the concrete pouring layer parallel to the extending direction of the cavity, so that tooth-shaped structures are formed at two ends of the concrete.

Through adopting above-mentioned technical scheme, make precast floor butt joint easier when butt joint installation each other, the installation operation high efficiency of being convenient for goes on.

To sum up, the utility model discloses a beneficial technological effect does:

(1) the shock resistance is excellent, the structure is stable, and the service life is long;

(2) the structure is light, the construction speed is high, and the construction period is shortened.
