[0029] 1. In the processing and manufacturing process, the foam filling block will move during the pouring of concrete because of its light weight, which cannot accurately meet the production process requirements, resulting in uneven wallboard and even local stress concentration problems, but the straw soil block 2 has a larger weight than the foam filling block, and the bonding performance of the straw soil block 2 and the anti-cracking panel is good, which will not move and float, which is beneficial to industrialized production, so that the pouring process will not move, and the requirements of industrialized production can be met;

[0032] 4. The straw and soil building block 2 not only meets the heat preservation and insulation requirements, but also has better sound insulation effect than foam blocks.

[0033] The bulk density of the straw and soil building block 2 is less than 650 kg / m 3 , and the thermal conductivity is less than 0.08.

[0034] The rear pouring cover plate 3 of the inner layer can be poured, and the thickness can be greatly reduced, reducing the cost of concrete pouring, and gypsum board can also be used for covering.

[0035] In the case of increasing the thickness of the middle layer, the thickness of the bottom layer and the top layer is reduced, which ensures the overall processing size and meets the requirement of structural strength.
