Description

Technical Field

[0001] This utility model relates to a wall structure. Background Technology

[0002] New energy-saving wall materials have extremely high thermal insulation performance. While reducing the consumption of electricity resources, the rational selection of targeted energy-saving wall materials can effectively reduce the energy consumption generated by internal air conditioning and heating systems. The application process of energy-saving building materials is simple and does not require a large investment of manpower and material resources, thus improving the efficiency of human resources and construction costs.

[0003] Polystyrene foam board, with its superior thermal insulation performance and lightweight nature, is one of the most common and widely used insulation wall materials. Its low thermal conductivity effectively prevents heat transfer and improves building insulation performance, making it suitable for use in exterior wall insulation in cold regions. The insulation principle of polystyrene board involves a foaming process that creates sealed air chambers within the board. Due to the small size of these chambers, heat transfer is effectively blocked, meeting the insulation needs of residential buildings. Besides wall design, it can also be used in roof insulation design.

[0004] The construction process for polystyrene foam board wall structures includes the following steps: measurement and layout, inspection and repair of any substandard wall surfaces, preparation of bonding mortar, pasting of insulation boards, installation of reinforcing mesh, installation of expansion bolts, and application of polymer-modified crack-resistant mortar. This construction technique is widely used, but after more than ten years of use, accidents involving polystyrene foam boards detaching from the wall frequently occur. This is because the connection strength between the components of the wall structure formed by this technique is poor, making it prone to hollow areas. The low bond strength between the polystyrene foam board and the bonding mortar also results in poor durability and poses safety hazards with long-term use. Utility Model Content
