Abstract
Description
Technical Field
[0001] The utility model relates to a sound insulation structure for a concrete thermal insulation wall, belonging to the technical field of concrete thermal insulation walls. Background Technique
[0002] A concrete thermal insulation wall is a building wall system that combines a concrete structure and thermal insulation materials. This wall structure not only has good structural strength and durability but also can effectively reduce energy consumption and improve the energy efficiency of buildings. Concrete thermal insulation walls are widely used in residential, commercial, and industrial buildings, etc., and have become one of the important energy-saving and environmental protection technologies in modern buildings.
[0003] However, although concrete has certain waterproof performance, when exposed to a humid environment for a long time, moisture may still penetrate into the interior of the wall, causing the thermal insulation material to get damp and reducing the thermal insulation effect. After the moisture enters the concrete wall, it will cause the corrosion of steel bars, thus affecting the strength and safety of the structure. The moisture in the wall will produce condensed water when the temperature drops, which will not only further damage the thermal insulation layer but also form condensed water droplets indoors, affecting the living comfort.
[0004] Therefore, a sound insulation structure for a concrete thermal insulation wall is proposed. Content of the Utility Model
[0005] In view of this, the utility model provides a sound insulation structure for a concrete thermal insulation wall to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.
