Problems solved by technology

The wall components disclosed in the above-mentioned patents have excellent properties such as light weight, heat preservation, sound insulation, and earthquake resistance, and can be used as formwork for pouring walls. The lightweight material of the component is mainly polystyrene foam particles, which leads to defects such as low strength, high water absorption, poor surface compactness, low impact resistance, poor impermeability, and poor durability of the formwork component.
The inability to bear the load due to low strength can be solved by pouring reinforced concrete lattice columns and beams, but as a wall, the wall surface must reach a certain strength and impact resistance. material can not achieve
Moreover, due to its unreasonable structural design, it not only cannot adapt to the design requirements of traditional Chinese architecture, but also cannot adapt to the needs of modern diversified architectural design, resulting in poor applicability, low wall strength, poor impact resistance, and production costs. A series of problems such as high price and high product price
