It has a multi-scale pore structure, and the material pores and macro-cavity structure are observed in detail, thereby passively regulating the indoor humidity and heat environment and isolating outdoor noise.

[0046] Bearing layer 2, such as Figures 6 to 9 As shown, a solid wall panel is installed on the outside of the insulation layer 1.

The material of the thermal insulation layer 3 in this embodiment is preferably aerogel, which has good sound insulation, heat insulation, and heat insulation effects, and the thickness is 1-2 mm. The thermal insulation layer 3 adopts a high-thermal-resistance, strong-fire-resistant thin layer material to reduce the influence of outdoor temperature fluctuations on the indoor thermal environment and play a heat protection function.

A plurality of grooves 43 adapted to the reinforcing ribs 21 are arranged in parallel on the inner side of the protective layer 4.

[0052] The wallboard unit provided by the present embodiment meets the wallboard heat preservation and insulation requirement by thickening the cavity heat preservation layer 1, which will result in that the wallboard thickness and self-weight are too large, which is not conducive to installation and anti-seismic. The single thickening high thermal resistance heat insulation coating has high cost and large preparation difficulty. Studies have shown that the thermal conductivity coefficient of each millimeter of the heat insulation coating is 0.015 W / m·K, which is equivalent to about 30 mm thick multi-cavity heat preservation layer 1, the thermal conductivity coefficient is 0.2 W / m·K, the outer connecting circle diameter of the cavity is 100 mm, and the wall thickness is 20 mm. The wallboard unit of the present embodiment adopts an inner cavity structure and an outer heat insulation coating, which is not a simple superposition of two structures, but a result of synchronous optimization of wall materials and layer structures.

[0053] The above is the introduction of the bionic wallboard unit structure provided by the present embodiment. The present embodiment also provides a preparation method of the above-mentioned bionic wallboard unit, as shown in Figures 14 to 15 The preparation method specifically includes the following steps.

[0056] Step 102, preparation of the bearing layer: the bearing layer is molded, the prefabricated heat preservation layer is placed on the inner side of the bearing layer before the material is initially cured, and the umbrella-shaped anchor is controlled to be anchored into the bearing layer by not less than 15 mm and the hollow wall is controlled to be deeply anchored into the bearing layer by not less than 2 mm, so that the chemical cementing force and the mechanical anchoring force between the heat preservation layer and the bearing layer jointly guarantee the connection between the two layers; the bearing layer material is demolded.

[0057] Specifically, the thermal insulation layer is prefabricated, and the thermal insulation layer is placed on the bearing layer before the initial setting of the bearing layer.

[0060] Specifically, when applying aerogel, the coating thickness needs to be uniform and fully covered. Aerogel is a high-thermal-resistance, strong-fire-resistant thin layer material that can reduce the impact of outdoor temperature fluctuations on the indoor thermal environment and play a thermal protection function.

[0061] Step 104, preparation of the protective layer: after the thermal insulation layer is set, the formwork is poured to cast the protective layer, so that the chemical cementing force between the protective layer and the thermal insulation layer and the mechanical engagement force together ensure the connection between the two layers; the protective layer material is removed, thereby obtaining a wallboard unit.

[0062] It should be noted that in this embodiment, the protective layer is removed when the strength of the protective layer material reaches 70% of the design strength, and those skilled in the art can set the design strength of the material at the time of removal.

[0063] The wallboard unit and the preparation method of this embodiment have the following advantages: the multi-level layer structure of material-structure integrated design performs its own function, realizing the multifunction of a single wallboard; the integration design of wallboard forming process and connection structure realizes the reliable connection of each level of layer structure and works together; the optimization of geometric configuration parameters of each level of layer structure under multiple performance targets realizes the balance of wallboard performance.

[0067] Step 202, according to the anti-seismic grade, the tie bar is arranged in the groove of the wallboard unit, the end of the tie bar needs to be anchored into the beam, the bonding material is filled in the groove to the height of 2 / 3 of the groove, the convex rib of the upper wallboard unit is embedded in the groove of the lower unit, and the bonding material is uniformly extruded and filled to the cavity between the groove and the convex rib under the action of the self weight of the upper unit.

[0068] Step 203, the wallboard unit needs to be built in staggered joints, the horizontal distance of the tooth joint is not less than 1 / 3 of the length of the unit, the tooth joint is embedded first, and then the self-compacting bonding material is used for grouting to connect.

[0069] Step 204, after the wallboard unit is completed, the caulking agent is used for caulking the chamfer part of the unit.
