异形伞状清水混凝土柱模板体系设计与施工技术

清水混凝土的判别标准主要集中于表面平整度和外观质量,其中表面平整度和模板刚度密切相关,为保证混凝土表面平整度,应避免模板发生两侧变形;外观质量则与混凝土配合比、浇捣技术和养护相关。本文针对异形清水混凝土柱成型质量控制进行探讨,以工程实例为背景,对清水混凝土柱组合钢模板设计与清水混凝土成型施工技术进行研究,分析阐述清水混凝土组合钢模板设计与施工控制要点。

Design and construction technology of formwork system of special umbrella-shaped fair-faced concrete column

The judging standards of fair-faced concrete mainly focus on the surface flatness and appearance quality. The surface flatness is closely related to the formwork stiffness. In order to ensure the concrete surface flatness, the deformation of both sides of the formwork should be avoided. The appearance quality is related to the concrete mix proportion, pouring and tamping technology and maintenance. This paper mainly discusses the forming quality control of special-shaped fair-faced concrete column, studies the design of composite steel formwork for fair-faced concrete column and the construction technology of as cast finish concrete, analyzes and expounds the design and construction control points of fair-faced concrete composite steel formwork.
