Therefore, the structure is simple, the protection frame is convenient to mount, and efficient production of the hollow slab is achieved.

Optionally, a plurality of inserting blocks are arranged on one side of the plate body at intervals, and a plurality of inserting slots for inserting the inserting blocks are arranged on the other side of the plate body at intervals.

Through adopting above-mentioned technical scheme, through the cooperation that sets up inserted block and slot, realize that the concatenation between two adjacent hollow core slabs is fixed, increase hollow core slab's stability in use and structural strength.

In summary, the present application includes at least one of the following beneficial technical effects:

the foam heat-insulating columns are arranged in the through holes, so that the heat insulating property of the whole plate body is improved by the foam heat-insulating columns, the hollow plate integrates bearing and heat insulation, and the performance of the hollow plate is improved;

the foam heat-insulating columns are arranged in a honeycomb shape, so that the plate body has the functions of sound absorption and noise reduction, and the performance of the hollow plate is further improved;

the protective frame is arranged on the outer edge of the plate body, so that the edge position of the plate body is protected, the phenomenon of collision and damage of the plate body is avoided, and the product quality of the hollow plate is ensured;

through setting up the structure succinctly to easy to assemble's protection frame realizes the high-efficient production of hollow slab.
