为进一步研究废旧木家具的回收利用状况和可能性,需要开展针对消费者的具体调研研究,通过两种不同类型的问卷设计,分别采用交叉分析法和回归分析法研究大众对于不同回收利用方面的认知度及倾向性。结果表明:在废旧木家具的回收利用过程中,回收服务对是否愿意购买存在独立的正向影响,回收方式、利用方法和策略对回收与再利用存在独立正向影响;社会应加强对废旧木家具回收利用的宣传,再生木家具在保证质量与环保性的同时可以针计对年轻人制定营销策略。 相似文献

近年来随着我国房地产装修和家具产业的快速发展,家具更新换代日渐成为趋势,废旧家具量日益增长,废旧家具回收利用也备受关注。笔者基于层次分析法(AHP法)和模糊数学原理对废旧木家具回收性能评估体系进行了研究,确定了废旧木家具回收性能评价一级指标为质量属性、外貌属性、数量属性和类别属性,其中质量属性包括完整度、材料性、使用年限、拆解性、变形度等二级指标;外貌属性包括样式、表面涂装、辅料等二级指标;数量属性包括成套性、件数等二级指标;类别属性包括类别性等二级指标。构建了废旧木家具回收性能评价体系的递阶层次结构模型,通过对废旧木家具回收性能的问卷调查以及评价指标权重的层次分析和信度分析,为废旧木家具回收性能评定提供了科学有效的评价标准和参考方法。 相似文献

循环经济强调有效利用资源和保护环境,是国际社会推进可持续发展的实践模式。针对目前废旧人造板家具极少回收造成资源浪费和环境压力等问题,通过对循环经济模式下废旧人造板家具生态利用进行资料整理,分析了国内外废旧人造板家具回收现状及问题,并以重构理论为基础,从时间重构(产品生命周期)、市场重构(家具回收市场)、资源重构(家具资源分类和创新再开发)三个层面,对废旧人造板家具生态利用进行了探讨,同时提出了相应重构策略。结果表明:可以在延长人造板家具产品生命周期、细化家具回收市场、创新材料再利用加工技术等方面进行生态改善和领域拓展。本文通过循环经济、生态设计和重构理论综合研究对中国家具行业可持续发展提供策略建议,同时对全球家具行业可持续发展起到一定的参考价值。 相似文献

运用灰色关联度分析法测算13个因素对中国向丝绸之路经济带沿线国家出口6类木质家具的影响程度,采用GM（1,1）模型预测2019—2023年中国对“一带”沿线国家6类木质家具出口额,在此基础上分析影响出口额走势变化的主要因素。结果表明:2019—2023年中国对“一带”沿线国家6类木质家具出口额均会上升,中国互联网普及率、中国GDP、中国家具制造业从业人员年度平均工资均是影响带软垫的木质框架坐具、卧室用木家具、起居室/餐厅和商店用木家具出口额走势的关键因素,25国人口总量、中国GDP、中国原木平均进口价格则是影响其他木质框架坐具、办公用木家具、厨房用木家具出口发展的关键因素。 相似文献

Compressed wooden plates and dowels were used to connect members in post-and-beam structures as a substitute for a steel fastener.
In order to take advantage of the characteristic properties of compressed wood and to achieve optimum joint performance, two
compressed wooden plates were used in each joint to give multiple shear planes for each compressed wooden dowel. Consequently,
this type of joint showed very good properties in pull-out and momen-trotation performance, and its engineering design could
be further optimized. This joint is expected to be introduced to many kinds of structural systems, including long-span frame
structures made of domestic timber found in Japanese residential houses. 相似文献

Timber is one of the most common materials used in traditional buildings worldwide. Our previous research has suggested that timber shear walls play an important role in resisting external loadings, such as earthquakes. Thus, improving the structural performance of in-filled shear walls can also improve that of the entire structure. In the traditional Taiwanese timber shear wall system, the embedment strength of beams and friction between wooden planks and beams significantly affect the strength of the shear wall. This article proposes a new method of reinforcing traditional timber shear walls in Taiwan by inserting teak and padauk strips into the grooves between wooden planks and beams to increase the embedment strength of beams and the friction between wooden planks and the hardwood strips. A total of 18 full-scale specimens were tested under reversed cyclic loading. The results revealed that the strength and energy dissipation capacities of a wooden shear wall can be significantly increased by inserting teak and padauk strips into the grooves between planks and beams. Furthermore, the simplified calculation method proposed in this study can be used to calculate the strength of both reinforced and unreinforced wooden shear walls with satisfactory agreement. 相似文献

Most old buildings in Korea are wood framed and, with age, deterioration is found in all wood components of antique buildings.
Insects and rapid changes in humidity are among the main causes of deterioration. To preserve antique wooden buildings, nondestructive
testing (NDT) methods are required. Various methods of nondestructive evaluation (NDE) such as X-ray, stress wave, drilling
resistance test, and ultrasound are used to inspect the safety of wooden antique buildings. The ultrasonic method is relatively
simple, inexpensive, and accurate. The rafters are one of the main components of antique buildings and are seriously affected
by deterioration. This study aimed to develop a nondestructive ultrasonic technique for evaluation of wooden rafter deterioration.
Regression models describing the relationship between the artificial deterioration of the specimen and ultrasonic parameters
were proposed. The method was found to be reliable for evaluating wooden rafter deterioration. 相似文献

In this study, we developed a new analysis method that enables numerical simulations of the collapse process of real-size
wooden houses and evaluated the accuracy thereof by carrying out numerical simulations by shaking table tests. The distinct
element method was adopted as the basic theory of our numerical analysis. This research is the first approach in which the
extended distinct element method was used for Japanese timber post-and-beam construction. The size of the analysis model is
a 5.5 m × 5.5 m, two-story real-size wooden house. The three analytical models were developed in terms of the strength of
exterior mortar walls. The simulation results were compared with the shaking table test results. One of the collapsing processes
of the numerical simulation corresponds well to the experiment results. Assessment of the possibility of collapse for real-size
wooden houses was determined to be possible using our newly developed numerical analysis method. 相似文献
