装配式混凝土剪力墙水平缝施工处理

Construction Treatment of Horizontal Joints of Assembled Concrete Shear Wall

我国20世纪70~80年代采用的预制装配式混凝土结构主要用于装配式大板住宅体系,以及预制圆孔板、大型屋面板、槽形板等预制构件的应用。由于在构件生产、安装施工及结构受力模型、构件连接方式等方面存在的问题,这些结构在抗震安全性、建筑物理性能、建筑功能等方面不同程度地存在着一些问题,所以,在20世纪90年代已经逐渐地被淘汰。如今,我国大部分建筑施工企业技术中心和许多高校的科研院所都具有了符合自身特点和需求的关于装配式剪力墙结构等方面的技术。在装配式混凝土剪力墙这一结构中,对其水平缝的施工处理极其关键,这直接关系到装配式混凝土剪力墙的抗震性能。论文主要对装配式混凝土剪力墙水平缝的施工处理进行简要分析,为现场装配式混凝土剪力墙水平缝施工处理的改良提供有利的参考,以便更好地保障建筑物的整体抗震能力和工程质量,减少不必要的损失。

Our country s and eighty s of the 20 th century is the prefabricated prefabricated concrete structure is mainly used large plate housing system, and the prefabricated circular orifice, large roof board, trough plate, etc. The application of prefabricated. Due to the production, installation of components and structure model and the way of component connection problems, these structures in seismic safety, physical properties and architectural function there are some problems in different degrees, in the 1990 s has gradually be eliminated.Nowadays, our country most of the construction enterprise technology center and many colleges and universities scientific research institutes have the conform to the characteristics and requirements of technology of prefabricated shear wall structure, etc. In the prefabricated reinforced concrete shear wall structure, the processing is the key to the construction of the horizontal seam, it is directly related to prefabricated concrete shear wall seismic performance. This article is mainly to the prefabricated concrete shear wall of the horizontal seam, made a brief analysis of the construction process of the prefabricated concrete shear wall horiz ontal seam construction process improvement to provide beneficial reference, in order to better safeguard the overall seis mic capacity of buildings and the engineering quality, reduce unnecessary losses.
