预制绑扎式无龙骨茅草屋面施工技术

Construction Technology for Prefabricated Binding Type Keel-Free Thatched Roof

非洲热带地区传统茅草屋面施工技术粗糙,导致成品屋面的耐久性、安全性较差,破损率、返修率极高。为解决此类问题,通过工厂化作业,按照统一规格预制编织茅草内衬和编织帘,在屋面斜檩条上先设立水平支撑,再将茅草内衬铺设在斜檩条外侧进行上下搭接,茅草编织帘沿屋架结构外侧环向铺设。此类无龙骨茅草屋面施工技术在满足观感和质量要求的同时,又能够简易并方便后期进行维护,为同类木结构房屋的茅草屋面施工提供技术创新。

The traditional thatched roof construction technology in the tropical regions of Africa is rough,which leads to poor durability and safety,high breakage rate and high repair rate of finished roofs.In order to solve such problems,the weaving thatch lining and the woven curtain are prefabricated according to the uniform specifications through the factory operation,the horizontal support is set on the inclined purlin of the roof,the thatched lining is laid on the outer side of the inclined purlin to lap up and down,and the thatched-woven curtain is laid along the outer side of roof truss.This kind of construction technology for keel-free thatched roof can meet the requirements of perception and quality,and meanwhile it is also simple and convenient for later maintenance and can provide technological innovation for the construction of thatched roofs of similar wood-frame houses.
