我国结构用规格材研究现状及开展产品认证初探

Research Status and Product Certification of Structural Dimension Lumber in China

文中结合我国木结构研究和推广历程,总结我国规格材研究现状和存在的问题,阐述我国产品认证发展和国内外实施制度,并对规格材在我国实施产品认证制度的可行性、必要性、认证模式以及亟需解决的问题进行了探讨;提出我国规格材开展产品认证需进一步扩大研究树种、加强基础性能研究、完善标准体系、细化认证制度的建议,且根据规格材在木结构建筑中的安全特性,应按国家强制产品认证制度深入开展研究。

The paper reviewed the research and promotion of wood structure in China,and summarized the present situation and existing problems of dimension lumber. Based on these,it expounded the development of product certification in China and the relevant implementation system at home and abroad and discussed the feasibility,necessity,certification model and urgent problems of implementing product certification system for dimension lumber in China. It was proposed that the product certification for dimension lumber needs to further expand the research on tree species,strengthen the research on foundation performance,improve the standard system and refine the certification system. According to the safety properties of the dimension lumber in wood structures,it should carry out the in-depth research on the national compulsory product certification system.
