Mold assembly for manufacturing concrete narrow-gap slatted floor and application of mold assembly

The invention belongs to the technical field of building materials and particularly relates to a mold assembly for manufacturing a concrete narrow-gap slatted floor and application of the mold assembly. The mold assembly comprises a mold and an isolating layer, wherein the mold comprises a base plate and a frame; the frame is formed by assembling four square side plates which are vertically arranged at the periphery of the base plate; a plurality of molding plates are vertically arranged on the base plate; and the isolating layer is attached to the base plate and the side plates. According to the mold assembly disclosed by the invention, the concrete narrow-gap slatted floor is produced by adopting the following method: firstly, uniformly spreading one thin layer of fine sands on the isolating layer, pouring a layer of concrete into the mold assembly and then starting a vibrating table for vibrating; secondly, putting the reinforcing mesh into the mold assembly, and continuously pouring concrete into the mold
