摘要： Disclosed is a sand aerated concrete panel pre-embedded with a wire box and a wire conduit and its preparation method. The concrete panel includes a sand aerated concrete panel, a steel bar mesh cage, a wire box and a wire conduit. The steel bar mesh cage includes a plurality of longitudinal main steel bars, a plurality of transverse auxiliary steel bars and a plurality of connecting iron pieces; the wire box and the wire conduit are fixed on the steel bar mesh cage; and the steel bar mesh cage, the wire box and the wire conduit are poured in the sand aerated concrete panel. The disclosure solves the problems of complicated procedures, high cost, environmental pollution caused by dust and noise in the prior art, avoids the potential quality hazards of the panels and wall structures caused by on-site slotting, reduces labor force, intensity and cost.

摘要： Disclosed is a fire-proof thermal-insulation board of aerated concrete of B02-level lightweight autoclaved sand and its preparation method. Components of the thermal-insulation board are quartz sand, lime, cement, gypsum, aluminum powder, and foam stabilizer, weight percentages of the components are: 56%˜60% of the quartz sand, 8%˜11% of the lime, 20%˜30% of the cement, 2%˜4% of the gypsum, 0.24%˜0.26% of the aluminum powder, and 0.02%˜0.03% of the foam stabilizer. The fire-proof thermal-insulation board is made of an inorganic non-metallic material with lightweight, non-inflammable property and good thermal-insulation performance. The present disclosure well solves the thermal bridge problem of external wall of the building, and has A1-level fire-proof performance and good durability with the same service life as the building. The present disclosure overcomes low product strength, and inconvenience in transportation and construction in the prior art, reduces types of admixture used in the manufacturing process, and reduces the manufacturing cost.
