Civil building self-heat-insulation wall and heat transfer process computing method of same

Abstract

The invention discloses a civil building self-heat-insulation wall and a heat transfer process computing method of the same. The heat-insulation wall comprises an interior brick wall layer close to the indoor side, an exterior brick wall layer close to the outdoor layer and an overlap brick layer, and the interior brick wall layer, the exterior brick wall layer and the overlap brick layer consist of a plurality of interior wall bricks, exterior wall bricks and overlap bricks respectively. The interior wall bricks are parallel to the corresponding exterior wall bricks, the overlap bricks perpendicular to each of the interior wall bricks and the exterior wall bricks are arranged at two ends thereof, and the interior brick wall layer, the exterior brick wall layer and the overlap brick layer surround to form an air layer. By optimized design of a wall enclosure structure, heat insulation properties of an exterior wall are improved without changing a traditional brick and building block production mode, the requirements on heat transfer coefficients of the exterior wall in the southern China are met, and cost for engineering construction can be saved; meanwhile, an excellent heat insulation effect can be achieved, and building energy consumption can be lowered.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a self-insulating wall of a civil building and a calculation method for the heat transfer process of the wall. Background technique [0002] Since 80% of the total heat transfer energy consumption of a building is lost by the heat transfer of the building envelope, the improvement of the thermal performance of the building envelope is of great significance for building energy conservation. Appropriate enclosure structure components and reasonable construction measures can meet various requirements such as heat preservation, heat insulation, lighting, ventilation, etc., which not only ensures a good indoor physical environment, but also reduces energy consumption, which is the basic condition for realizing building energy conservation . [0003] The energy-saving design of the enclosure structure mainly involves factors such as exterior walls, roofs, doors and wi...

AI Technical Summary

Problems solved by technology

[0004] Urban buildings mainly improve the thermal performance of external walls by laying thermal insulation materials on the external walls. However, the construction cost will increase due to the laying of thermal insulation materials, which seriously restricts the promotion of energy-saving technologies for traditional civil enclosure structures in some rural areas.
