Problems solved by technology

After the enclosure structure has undergone insulation measures, due to the drastic temperature changes in the insulation layer, it is easy to form condensation, which increases the humidity of the insulation material and destroys the thermal performance, and condensation often forms inside the enclosure structure, resulting in mold
Therefore, building thermal insulation is a systematic project, and it is necessary to fully consider the damage to the structure caused by factors such as temperature field and thermal stress. At present, it is difficult to achieve the expected goal of reducing energy consumption by using thermal insulation materials alone without in-depth study of system theory.
[0003] At present, the enclosure structure insulation schemes adopted by various countries do not fully consider t...

Abstract

The invention relates to a building envelope structure, in particular to a dew formation-preventing building envelope structure for different thermal areas. The structure comprises a heat preservation layer, wherein a composite grid reinforcing rib waterproof vapor-permeable film coiled material is arranged on one side of the heat preservation layer; and a metal-plated waterproof vapor-isolating film coiled material or a surface non-woven cloth composite waterproof vapor-isolating film coiled material is arranged on the other side of the heat preservation layer. The composite grid reinforcing rib waterproof vapor-permeable film has high waterproof property and vapor permeability, and the metal-plated waterproof vapor-isolating film coiled material and the surface non-woven cloth composite waterproof vapor-isolating film coiled material have high waterproof property and vapor isolating property, so that dews are difficult to form on the building envelope structure. A surface metal-plated layer has good moistureproof and reflecting functions and the reflectivity of over 90 percent, effectively reduces building energy consumption and is suitable for curtain wall structures; and the surface composite non-woven cloth is characterized by high compatibility with cement mortar and other binders, and is more suitable for solid facing bricks or coating outer walls.

Description

technical field [0001] The invention relates to a building enclosure structure, in particular to an anti-condensation enclosure structure for buildings in different thermal regions. Background technique [0002] When the temperature somewhere in the building structure is lower than the dew point temperature, condensation will form when the water vapor in the indoor air reaches saturation, making the building structure damp. In traditional buildings without thermal insulation measures, the temperature difference of the envelope structure does not change much. In the southern region, the inner surface of the envelope structure is prone to condensation during the rainy season, while in the cold northern regions, condensation generally does not occur. After the enclosure structure has undergone insulation measures, due to the drastic temperature changes in the insulation layer, it is easy to form condensation, which increases the humidity of the insulation material and destroys ...
