The invention provides a thatch house roof
surface structure and a construction method thereof. The structure comprises a roof structure layer, and the roof structure layer comprises a large edge, a small edge, a yellow mud bottoming layer, a yellow mud connecting layer, a yellow mud layer and a
ridge. The yellow mud bottoming layer is laid on the structure layer, the small edge is laid on the yellow mud bottoming layer at the extension position of a roof, the yellow mud connecting layer is laid on the small edge, the large edge is laid on the yellow mud connecting layer in the roof directionin sequence, the yellow mud layer is laid on the large edge again, and a thatch layer is laid on the yellow mud layer finally. According to the structure, the excellent physical properties of thatch materials are utilized, and the construction method that the thatch materials are constructed according to a traditional process is adopted, so that the construction of the thatch house is more experienced, handmade, standardized and industrialized. The thatch materials serve as a roof
surface layer, the heat preservation and insulation performance of the thatch materials is utilized, meanwhile, due to the fact that the thatch materials have the anti-
corrosion and windproof performance, a decorative material can be exposed, an anti-
cracking material and a paint do not need to be additionally arranged for protection, and unification of functionality and decoration is achieved. By means of the mature construction method, the style and feature of a traditional thatch house dwelling are reserved, and the performance and quality of the thatch house are improved.
