卷扬机吊装高耸异型结构清水砼挂板关键施工技术

清水混凝土挂板属于预制混凝土外墙挂板范畴,目前,传统的混凝土挂板工艺趋于成熟,并且国家具有相关标准图集,但对结构为高耸、外型均为不规则的倾斜立面的挂板安装,尤其对外观设计分块要求转角部位采用大转角板的安装,传统工艺不能满足要求。随着国家经济的发展,市场对建筑高度及建筑造型需求越来越高,建筑造型的奇特性给传统施工工艺带来了挑战,我公司施工的长沙滨江文化园景观塔工程建筑外形新颖,建筑外立面均为不规则的倾斜外墙,阴阳角多,且角度多样,倾斜外墙的挂板高度近百米。每块清水混凝土挂板的规格尺寸大,重量重,挂设高度高,单块板重达0.8t,这对挂板的加工精度、挂板安装精度和安装方法提出了更高的要求。

Key Construction Technology of Fair-faced Concrete Panel of Hoist Hoisting Towering Special-shaped Structure

The fair-faced concrete panel belongs to category of pre-cast concrete external wall hanging board.At present,conventional concrete panel technology is mature,and the country has relevant standard atlas,however,for the installation of hanging board of tilt facade with tall structure and irregular shape,especially for the installation of using large corner panel in the corner parts required by appearance design block,the traditional technology can not meet the requirements.With the development of national economy,the market has increasingly high demand for building height and architectural modeling,strange characteristics of architectural modeling brings challenges to the traditional construction process,external form of Changsha Binjiang cultural landscape tower which is built by Hebei Construction Group Co.,Ltd.is novel,and building facade is irregular tilt exterior wall,has more yin and yang corners and diversiform angles,the height of hanging board for tilt exterior wall is nearly one hundred meters.Size of each fair-faced concrete panel is large and has heavy weight and high height,single-board weighs 0.8t,which puts forward higher requirements for hanging board’s accuracy of processing,installation accuracy and installation method.
