两项推荐性标准批准发布《柔性屋面防水技术规程》CECS29∶91和《建筑中水设计规范》CECS30∶91两项推荐性标准已批准颁布。前一项标准适用于一般工业与民用建筑的屋面防水工程,温度适用范围-40～80℃。后一项标准适用于建筑物生活污水回收利用(厕所冲洗用或其它用途) 的供水系统设计。 GEM门式脚手架通过鉴定我国近几年开发的门式脚手架多是仿制日本的。由于功能不全,使用中有一定的局限性。北京市建筑工程研究所最近研制成功的GEM门式脚手架是一种新型的多功能门式钢管脚手架,与现有门式脚手架相比,其设计更为合理,且刚度增大、承载力提高、稳定性好、功能多、适用范围更加广泛,具有国际先进水平。大跨度框架施工应用爬模工艺四川省建三公司二处在省公安厅某工程中将爬架施工工艺用于大跨度钢筋混凝土框架结构,其跨度达8.5m,总高度为9.6m,为目前国内最大跨度爬架系统。它具有自重轻、易于爬升和下降等优点,同时有4个操作层供主体结构施工和外装饰时
The two recommended standards approved the issuance of two recommended standards CECS29:91 and CECS30:91, Code for Technical Specifications for Flexible Roof Water Protection, which have been approved and promulgated. The former standard is applicable to roof waterproofing projects for general industrial and civil buildings, with a temperature range of -40 to 80°C. The latter standard applies to the design of water systems for the recycling of domestic sewage from buildings (flushing or other uses for toilets). The GEM portal scaffolding has identified many of the portal scaffoldings that have been developed in China in recent years as copying Japan. Due to incomplete functions, there are certain limitations in use. The GEM gate scaffold recently developed by the Beijing Institute of Civil Engineering and Architecture is a new type of multi-purpose steel pipe scaffold. Compared with the existing portal scaffold, the design is more reasonable, and the rigidity is increased and the bearing capacity is improved. It has good stability, many functions, and a wider range of application, and it has advanced international standards. Large-span frame construction application climbing mold technique Sichuan Province Jiansan Company No.2 in the Provincial Public Security Bureau project Climbing frame construction process for large-span reinforced concrete frame structure, its span of 8.5m, total height of 9.6m, is currently China’s largest span climbing system. It has the advantages of light weight, easy to climb and descent, etc. At the same time there are 4 operating layers for main structure construction and exterior decoration.
