Press the fiber reinforcement thin plate to follow the example of or slurry flowing process production moulding, make by autoclave in 8~15 hours (steam pressure is at 8~15 atmospheric pressure) again to copy;

2. two panels are inserted the mold mould frame both sides that are furnished with the steel pipe of loosing core, the coarse hair side of two panels is at the inboard conduct bonding surface mutually bonding with core body;

3. after getting core material ready metering, evenly obtain mix after the stirring with concrete mixer;

4. the mix that will obtain after will evenly stirring with concrete pouring equipment injects in the mold mould frame;

5. the core body vibratory concrete is closely knit;

6. the steel pipe of loosing core after the cement initial set;

7. the demoulding behind natural curing or the heating curing;

8. natural curing was finished finished product more than 14 days.According to the different definite curing times of cement type, general sulphate aluminium cement needs natural curing more than 14 days.

The invention has the beneficial effects as follows: press fiber reinforcement thin plate or fiber reinforcement low alkalinity cement building slab as panel owing to adopt to steam, rupture strength is higher, contract with dry rate and the wet rate that rises are lower, solve wallboard assembly unit seam owing to the crack problem that drying shrinkage causes, improved shock resistance, bending resistance rupture load and the rupture strength of wallboard.Have lightening hole according to core body concrete material density difference on the core body, lightening hole can be according to the different hole ratios of adjusting of core body concrete material density, the difference of functions such as the sound insulation that can require according to wallboard, heat insulation, insulation is selected the core body raw material, the scope that can be used as core material simultaneously is also more extensive, can adopt industrial residue and various aglite as core material in a large number.The optional material of the present invention is extensive, and cost of production is low, waterproof, every wet, heat insulation, fireproof performance is good, can follow closely and can saw.Be used for the internal partition for building body, building area utilization rate height, the construction efficiency height, wall surface levelling is attractive in appearance, need not batch ash.
