摘要:胶合木轻质且具有很高的强重比,与大跨空间结构的要求十分契合。在我国“双碳”目标的背景下,胶合木大跨空间结构具有优势。太原植物园中展览温室建筑采用胶合木结构,其造型呈“贝壳”形状,其中1#温室最大跨度为89.5m,最大高度29.5m,采用双向叠放胶合木梁形成网壳结构体系;太原植物园水上餐厅建筑跨度为21m,采用密肋叠合胶合木梁;上海滴水湖人行桥的F桥跨度48m,采用胶合木空间桁架结构体系。以3个已竣工工程为背景,阐明了胶合木大跨空间结构设计关键性技术,其中新颖的结构体系及节点设计为胶合木结构创新提供依据,促进并拓展我国胶合木大跨空间结构的发展。

Abstract: Glulam is lightweight and has high-bearing efficiency, which coincides with the requirements of large-span space structures. Under the background of “double-carbon” target in China, the large-span space structure of glulam has advantages. The structure of the exhibition greenhouses in Taiyuan Botanical Garden is made of glulam, and its shape is in the shape of a shell. The maximum span of the 1# greenhouse is 89.5 m, and the maximum height is 29.5 m. The reticulated shell structure system is formed by adopting two-way stacked glulam beams. The floating restaurant in Taiyuan Botanical Garden has a span of 21 m, which is made of ribbed laminated glulam beams, and the F bridge of Dishui Lake Pedestrian Bridge in Shanghai has a span of 48 m, which is made of glulam space truss structural system. Based on the background of three completed projects, the key technology of the design of the large-span space structure was expounded, in which the novel structure system and joint design provide the basis for the innovation of the glulam structure, to promote and expand the development of glulam large-span space structure in China.
