2 0 2 1年5月混凝土转换层设计构造及施工工艺张 恒(中国建筑第二工程局有限公司,北 京 100160)[摘要]在高层建筑中,转换层可将功能不同的2 个部分进行结构形式转换,从而保证建筑整体的稳定性。由于转换层的
受力情况比较特殊,因此为保证其功能的稳定发挥,需结合建筑的结构特点、使用功能等开展科学设计。首先从转换梁、框支
柱 2 部分概述了转换层设计要点,随后基于转换层施工流程,着重介绍了预留施工缝、温度测控、转换结构徐变、混凝土浇筑
等方面的技术要点,为现代高层建筑转换层的施工提供了借鉴。[ 关 键 词 ] 混 凝 土 结 构 ;转 换 层 ;施 工 缝 :裂缝控制[中 图 分 类 号 ]T U973.3 : T U974 [文 献 标 志 码] B [ 文 章 编 号 ] 1001-523X (2021) 09-0031-02遴逢技期计据 心统卷第源统第卷逢 术据选 光(据技统卷第源统期(据 全逢源疚据(刊(计升 (文 光(据源卷逢统逢 全卷术据技文逢卷 筑刊((卷位疚术据计 HengAbstract ] In the commercial and residential high-rise buildings, the transfer floor can transform the structural form o f the two
parts with different functions, so as to ensure the overall stability o f the building. Due to the special stress condition o f the transfer floor,
in order to ensure the stable function o f the transfer floor, it is necessary to carry out scientific design combined with the structural
characteristics and use functions o f the building. The design points o f transfer floor from two parts o f transfer beam and frame pillar
are first summarized, then based on the construction process o f transfer floor, the technical points o f reserved construction joints,
temperature measurement and control, transfer structure creep, concrete pouring, etc. are focused o n, which provides a certain
