【摘要】：钢铁、水泥、粘土砖等传统建材存在环境污染严重、能量消耗大等缺陷,利用绿色、环保和可再生木质材料制造现代重型木结构,不仅能实现木质资源的高附加利用,也能促进我国绿色、低碳建筑的快速发展,落实我国资源节约和环境保护的基本国策,具有重要经济、社会和生态效益。现代重型木结构不同于传统木结构,它是以木结构工程材为主要建筑材料,采用现代木结构设计和建筑技术建造的融美感、功能性与高性价比于一体的结构体系,在融入高新加工处理技术后,不仅具有自然、美观、环保、易维护、工程材可循环再生利用等优点,还具有防潮防腐、防火防蚁、稳定性高、耐久性好、施工周期短、造价低等特点。现代重型木结构在北美、北欧等发达国家发展已相当成熟,而在我国它还是一个较新的结构体系,目前国内对现代重型木结构的研究还十分有限。为进一步了解研究现代重型木结构的使用性能,结合国家林业公益性行业科研专项“木结构工程材制造及应用关键技术研究与示范”(201304504)、国家林业局引进国际先进林业科学技术项目“现代木结构桥梁工程材制造应用技术引进”(2010-4-14)和湖南省自然科学基金项目“现代木结构构件的力学性能及应用基础研究”(12JJ5012),本文通过现代重型木结构的设计、构件加工制造、构件拼装和结构安装等,对胶合木制造工艺进行了分析；根据国外现代重型木结构应用的成功案例,研究现代重型木结构建造技术,并将该技术成功应用于国内首座跨高速公路主线的现代木结构人行桥。本文主要的结论和创新成果如下：1.对国内外胶合木制造工艺进行了对比分析,提出了胶合木制造过程中值得注意的几个关键之处。2.通过对国外现代重型木结构应用成功案例的研究,得到了现代重型木结构建造技术的关键环节,提出了现代重型木结构建造技术的应用要求。3.基于现代重型木结构建造技术在国内首座跨高速公路主线现代木结构人行桥建造的应用,对现代木结构桥梁进行了成桥试验研究,结果证实了该技术应用的可靠性和适用性,为我国现代重型木结构的推广应用提供了技术支持和试验基础,具有很好的示范作用。
[Abstract]:Iron and steel, cement, clay brick and other traditional building materials have serious environmental pollution, large energy consumption and other defects. The use of green, environmental protection and renewable wood materials to manufacture modern heavy wood structures can not only achieve high additional utilization of wood resources. It can also promote the rapid development of green and low-carbon buildings in China, implement the basic national policy of resource conservation and environmental protection in our country, and have important economic, social and ecological benefits. It is a kind of structure system which takes wood structure engineering material as the main building material, adopts modern wood structure design and construction technology, and integrates function and high performance and price ratio. It is not only natural after it is integrated into high and new processing technology. Beautiful, environmentally friendly, easy to maintain, recycling and reusing engineering materials. It also has the advantages of moisture-proof and anti-corrosion, anti-fire and anti-ant, high stability, good durability, short construction period, low cost, etc. Modern heavy wood structures in North America, The developed countries such as Northern Europe have developed quite mature, but in our country it is still a relatively new structure system. At present, the research on modern heavy wood structure is still very limited in our country. According to the national forestry public welfare industry scientific research special item "the key technology research and demonstration of wood structure engineering material manufacture and application" (201304504), the State Forestry Administration introduced the international advanced forestry science and technology project "the modern wood structure bridge engineering material manufacture should. In this paper, the mechanical properties and applied basic research of modern wood structure members are introduced by introducing "Jiao2010-4-14)" and the project of Hunan Natural Science Foundation "12JJ501212". Through the design of modern heavy-duty wood structure, The manufacturing technology of glued wood is analyzed, and the construction technology of modern heavy wood structure is studied according to the successful cases of the application of modern heavy wood structure in foreign countries. The technology has been successfully applied to the first modern wooden footbridge across the main line of highway in China. The main conclusions and innovative results of this paper are as follows: 1.Contrastive analysis of the manufacturing technology of glued wood at home and abroad. Several key points in the manufacturing process of glued wood are put forward. 2. Through the study of successful cases of the application of modern heavy wood structures abroad, the key links of the construction technology of modern heavy wood structures are obtained. Based on the application of modern heavy-duty timber structure construction technology in the construction of the first modern wooden footbridge across the main line of highway in China, the bridge completion test of modern timber structure bridge is carried out. The results confirm the reliability and applicability of the technology, and provide technical support and experimental basis for the popularization and application of modern heavy wood structures in China. It has a good demonstration function.
