摘要
目的研究装配式夹芯保温板墙体拉结件的技术性能,构建评价体系,提供拉结件选用标准,实现装配式夹芯保温墙板质量和安全性能的提升.方法定义材料性能、结构性能、提升性能为一级指标,强度、弹性模量等九项性能为二级指标,通过隶属度分类法获得相似度评分,用层次分析法构建成对比较判别矩阵并确定指标权重,通过调研国内外相关规范指南和技术手册为指标评分提供依据,最后提出装配式夹芯保温墙板拉结件性能指标评价体系.结果选取某装配式夹芯保温墙板项目进行分析,对两种不同材质拉结件进行性能指标评价评分,分别得出评价结果,判别哪一种拉结件更适用于实际工程.同时对高性拉结件进行判别,验证了评价模型应用的可行性.结论针对拉结件深化设计建立指标评价模型,对于提升装配式夹芯保温墙板各方面性能具有重要意义.
Study the technical performance of connectors of prefabricated sandwich insulation board,construct an evaluation system,and provide the selection standard of connectors,to improve the quality and safety of the assembled sandwich board.Material properties,structural properties and lifting properties are defined as primary index,and nine properties,such as strength and elastic modulus,are defined as secondary index.Similarity scores were obtained by membership classification,the analytic hierarchy process was used to construct the comparison discriminant matrix and determine the index weight.According to the investigation of relevant domestic and foreign standard guidelines and technical manuals to provide the basis for index scoring.Finally,an evaluation system of performance index of prefabricated sandwich board is proposed.An assembly type sandwich insulation board project was selected for analysis,and the performance index of two different materials were evaluated and scored,and the evaluation results were obtained respectively.Distinguish which kind of connector is more suitable for practical engineering.At the same time,the high energy connectors are identified.And the feasibility of the evaluation model is verified.It is of great significance to establish an index evaluation model for the deepening design of connectors to improve the performance of the assembled sandwich boar.
