聚苯板保温施工应注意的几个问题

结合自身工作实践,针对墙体聚苯板保温施工中出现的质量问题,探讨了施工质量控制措施,从原材料,工序验收,细部节点三方面进行了具体阐述,以保证墙体保温施工质量。

外墙PU发泡保温装饰一体板施工技术

目前,国内建筑保温行业外墙保温体系普遍采取现场施工,保温作业和外墙装饰作业分步进行,不仅工艺繁琐、效率低、工期长,且施工人员的操作技能和作业环境严重影响工程质量,甚至会造成起鼓、开裂、脱落。通过国内外保温技术分析得出,在施工过程中采用PU发泡保温装饰一体板粘贴安装在建筑物外墙上,达到外墙保温和外墙装饰的双重效果,工期短、不起鼓、不开裂、不脱落、质量可靠。

Advances in numerical simulation of demolition blasting

The applications of numerical simulation in demolition blasting were reviewed.Several methods of numerical simulation in demolition blasting were introduced.The strength and weakness of the numerical methods mentioned in this paper were also indicated,respectively.Furthermore,the solid lattice model in the frame of discrete element method(DEM),which was developed by the author and his team,was detailedly described.The existed problems in the current numerical simulation methods of demolition blasting were presented and the future trend of the numerical simulation is finally prospected.
