Thermal insulation structure of traditional residence pitched roof in regions south of Yangtze River

Abstract

The invention discloses a thermal insulation structure of a traditional residence pitched roof in regions south of the Yangtze River. Extruded polystyrene boards or rock wool boards serve as thermal insulation materials of the traditional residence pitched roof in the regions south of the Yangtze River so that the thermal performance of the traditional residence roof can be improved. Rafters are laid on roof purlines of a residence wood structure beam frame, cedarwood roofing boards which are 8 mm thick are densely laid on the rafters, thermal insulation boards which are 50 mm thick, cedarwood roofing boards which are 12 mm thick and ethylene-propylene-diene-terpolymer waterproof rolls are sequentially laid on the cedarwood roofing boards which are 8 mm thick, and the waterproof rolls are paved with Chinese-style tiles. Extruded polystyrene boards or rock wool boards which are 50 mm thick are adopted as a thermal insulation layer of the roof, the summer indoor thermal environment in a traditional residence in the regions south of the Yangtze River can be greatly improved, the added thermal insulation layer in the roof structure is not exposed indoors or outdoors, and therefore it is guaranteed that the original roof appearance of the traditional residence is not changed. Meanwhile, the roof is further provided with the waterproof rolls, and the waterproof performance of the roof is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a thermal insulation structure of a sloping roof of a traditional residential building in the south of the Yangtze River. Background technique [0002] In the traditional houses in the south of the Yangtze River, the roof is a relatively prominent weak link for the indoor thermal environment in summer. The summer in the Jiangnan area is hot and the sunshine hours are long. The roofs of traditional houses in the south of the Yangtze River are generally simple in structure, mainly composed of small blue tiles and wooden watchboards, with small thermal resistance, and a large amount of solar radiation heat from the roof is transmitted into the room, which is an important factor causing high indoor temperature in summer. In the maintenance and repair of traditional residential buildings in the south of the Yangtze River, on the one hand, it is necessary ...
