【摘要】：随着我国建筑业的不断发展，规模庞大的基础设施建设正在迅速地改变中国的面貌，社会环境对建筑作品的要求越来越高，现浇清水混凝土在这方面起到了积极的作用，而清水混凝土更是表现出了素面朝天的优质品位，国内对此还未有比较成熟的施工工艺技术，而且其施工难度较大，变动因素较多，很少被国内的业主和设计师采用，加之目前国内建筑业对清水混凝土认识不够，真正成功的清水混凝土建筑屈指可数。通过归纳清水混凝土常见质量缺陷起因，分析结合本项目特点的基础上，根据以往工程的经验，制定半框模板控制标准和混凝土施工控制措施，确保清水砼施工的顺利完成。从模板工程、测量放线、混凝土工程等方面对清水混凝土施工进行控制，可以有效地防止清水混凝土观感质量缺陷的产生。科学技术是第一生产力，积极运用建筑业新技术，是施工单位义不容辞的责任。本文主要采用调查分析、系统总结、实践证明的方法，对半框模板的清水混凝土如何进行施工控制的实施进行详细阐述。本文结合了国内比较成功的清水砼施工技术，主要分析清水混凝土质量控制措施。针对清水混凝土观感质量的要求，通过介绍半框模板清水砼技术在民用建筑中的应用，探讨建设项目如何推广此项技术。万科云鹭湾II-5地块项目（15#楼），建筑面积3107.36m2，此工程就运用了半框模板体系结合清水混凝土施工控制，，出色的完成了清水混凝土的效果。成型后的混凝土表面不作任何修饰，强调混凝土的自然表现机理，以混凝土自然状态为饰面的混凝土。同时为提高混凝土的耐久性，本工程采取了多项措施加强，实践证明其效果明显，大大提高了使用寿命。
[Abstract]:With the continuous development of the construction industry in our country, the large-scale infrastructure construction is rapidly changing the face of China, and the social environment is demanding more and more construction works. The cast-in-place concrete has played an active role in this respect. And the fair-faced concrete has shown the high quality grade of the plain face toward the sky. There is no comparatively mature construction technology in our country, and its construction is more difficult and varied, so it is seldom adopted by domestic owners and designers. In addition, the current domestic construction industry does not know enough about fair-faced concrete, the real success of fair-faced concrete buildings can be counted. Through summing up the causes of common quality defects of fair-faced concrete and analyzing the characteristics of this project, according to the past engineering experience, the control standard of half-frame formwork and the construction control measures of concrete are formulated to ensure the smooth completion of the construction of fair-faced concrete. To control the construction of fair-faced concrete from the aspects of formwork engineering, measuring and laying line, concrete engineering and so on, can effectively prevent the appearance quality defects of fair-faced concrete. Science and technology is the first productive force, and the new construction technology is used actively. Is the construction unit is duty-bound responsibility. In this paper, the methods of investigation and analysis, systematic summary and practice prove are used to explain in detail how to carry out construction control of half-frame formwork fair-faced concrete. This paper mainly analyzes the quality control measures of fair-faced concrete combined with the successful construction technology of fair-faced concrete in China. According to the quality requirement of fair-faced concrete, this paper introduces the application of half-frame formwork concrete technology in civil buildings, and discusses how to popularize this technique in construction project. Wanke Yunluwan II-5 site project has a building area of 3107.36m2.This project uses the half-frame formwork system combined with the construction control of fair-faced concrete, and the effect of fair-faced concrete is well completed. The surface of formed concrete is not modified, and the natural performance mechanism of concrete is emphasized. At the same time, in order to improve the durability of concrete, a number of measures have been taken to strengthen the project. The practice shows that the effect is obvious and the service life is greatly improved.
