Embodiment Construction

[0120] 1. Embodiment: figure 1 It is a schematic diagram of the external thermal insulation wall structure of the present invention, as figure 1 As shown, from outside to inside are cement board 1, outer air layer 2, polymer elastic coating material 3, plywood 4, flame-retardant insulation material 5, cement mortar leveling 6, base load-bearing wall 7, polyethylene film 8. Inner air layer 9. Gypsum board 10.

[0121] The ratio of the sum of the upper and lower opening areas of the gypsum board to the volume of the inner air layer is not less than 0.05 (1 / m), the thickness of the air layer is between 10mm and 60mm, take 20mm, clean the base surface, and place it in the interior of the base load-bearing wall Adhere to a layer of polyethylene film on the side for waterproofing and fix it, and then fix the gypsum board on the load-bearing wall of the base layer with bolts 12. The fixing gap must be sealed with a sealing material, and the distance between the fixing parts is 200mm...

Abstract

The invention discloses a design method for the inner side and the outer side air layer thickness of a condensation-preventing external thermal insulation wall body, and belongs to the technical field of wall body structures. The design method comprises the steps of (1) building a heat transmission and humidity transmission mathematical model of the external thermal wall body, (2) identifying a humidity accumulation rate, and (3) solving a heat and humidity coupled equation by utilizing a finite volume method. The design method fundamentally overcomes the fatal defects that the interior of a building wall body is easy to humidify, condense and mildew, and airtight, and is capable of comprehensively improving heat-insulating and energy-saving properties and an indoor living comfort level of a building space enclosing structure in a breakthrough mode.

Description

Technical field [0001] The invention relates to a method for designing the thickness of air layers inside and outside an anti-condensation external thermal insulation wall, belonging to the field of wall structure design. Background technique [0002] In the 21st century, energy shortage still restricts the sustainable development of society. In order to complete the "Eleventh Five-Year Plan" and the 2015 long-term plan, the use of thermal insulation materials in buildings is the most effective way to save energy, and its effect is also the most obviously. At present, the external thermal insulation of external walls is a measure vigorously promoted by the Ministry of Construction to improve the thermal insulation of building envelope structures. However, in areas with high humidity and much rain in the south, especially in buildings that use air conditioners in winter, in order to save energy, there are generally no ventilation settings on the walls or windows. Domestic w...
