Description

A thermal insulation structure for building exterior walls Technical Field

[0001] This utility model relates to the field of building energy conservation technology, specifically a building exterior wall thermal insulation structure. Background Technology

[0002] Traditional exterior wall insulation often uses a single material, which suffers from high thermal conductivity, easy cracking, and poor fire resistance. While polystyrene boards are lightweight and low-cost, their poor thermal conductivity limits their insulation performance, and they are prone to softening and deformation at high temperatures, leading to insulation layer detachment or cracking. Rock wool, although possessing good fire resistance, is highly hygroscopic; prolonged exposure to damp environments can cause it to absorb water and fail, reducing its insulation effectiveness. Furthermore, the fibers are easily dispersed during construction, impacting worker health and the environment. In addition, single-material insulation lacks structural strength and impact resistance, making exterior walls susceptible to thermal stress or other damage. External forces can cause cracks, leading to problems such as water seepage and mold growth, which seriously affect the service life of buildings and the comfort of living. Some composite structures attempt to improve performance by combining multiple layers of materials, but they still have defects such as weak interlayer bonding and complex construction. For example, traditional thin plastering systems use bonding mortar to fix insulation boards, but the bonding strength between the mortar and the base wall is greatly affected by construction technology and environmental factors, which can easily lead to problems such as hollowing and falling off. While some sandwich insulation structures have better insulation effects, the construction process is complicated, requiring multiple pours of concrete or masonry of walls, resulting in long construction periods and high costs.

[0003] Based on this, a thermal insulation structure for building exterior walls is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention
