混凝土拱板屋盖将承重、防水与保温三种功能结合在一起,是冷库建筑中的一种新型屋盖系统。济南果品研究所工程屋盖跨度为15m,厚度仅5cm。原设计要求先预制中间的腹板,然后再任建筑物原位地面上整体预制,每3m分段,再逐段提升至设计标高后拚装。济南第三建筑公司在施工中将上弦弧形板分为8块预制,然后连同腹板运至现场就位安装,只有下弦平板支模现浇,减少了难度,简化了操作。采用改革后的工艺施工,不但保证了工程质
The concrete arch roof combines the three functions of load-bearing, waterproof and heat preservation, and is a new type of roof system in cold storage buildings. The Jinan Fruit Research Institute has a project roof span of 15m and a thickness of only 5cm. The original design requires that the intermediate webs be prefabricated first, and then be prefabricated as a whole on the in-situ ground of the building. Each 3m segment should be assembled and then lifted up to the design elevation. In the construction, Jinan No. 3 Construction Co., Ltd. will divide the winding chord board into 8 prefabricated parts, and then transport it to the site together with the webs to be installed in place. Only the lower chord flat-plate mold will be poured, reducing the difficulty and simplifying the operation. The use of reformed process construction not only ensures the quality of the project
