【摘要】：国内外城市化进程的发展越来越快,城市建筑密度越来越大。闹市区建设开发项目,开发商会尽可能贴建筑红线利用地下空间,导致地下外围护结构必须采用单侧支模体系。作为施工管理方采用何种模板体系、并保证单侧模板施工安全,应引起施工项目管理的高度重视。王府井国际品牌工程地下室外围护结构外边线距离建筑红线仅有2米,在围护结构与建筑红线之间设有直径1.2米的护坡桩及相应止水帷幕,而且外围护结构墙体主要厚度800mm,而且地下室外围护结构外墙工程防水为外防内贴自粘防水材料。因此,该工程地下室围护结构墙体模板只能选择单侧支撑模板体系。本文以王府井国际品牌中心工程地下室外围护结构为实例,从施工角度对混凝土单侧支撑模板体系进行了研究。内容包括:1、模施工工艺在我国的应用和发展情况。2、结合王府井国际品牌工程实例,根据工程特点,研究地下室外围护结构墙体混凝土单侧支模模板体系的设计选型、施工工艺,对其模板、支架、以及分步浇筑混凝土施工等全过程施工技术问题进行了详细的研讨。3、根据施工工艺,对地下室外围护结构混凝土单侧模板支架体系的强度、刚度以及稳定性进行了验算。确保了该单侧模板支架体系的强度、刚度和整体稳定性,从技术角度确保了该单侧支撑模板体系的安全。4、结合实例工程质量目标、安全文明施工目标,研讨了单侧支撑模板体系在施工管理中的模板质量标准、质量保证、以及安全文明施工保证措施等多方面问题,并对该单侧模板支架体系施工效果进行了总结。通过研究,总结出混凝土地下室外围护结构墙体单侧支模模板体系的一套方法和管理控制措施,为类似工程施工提供借鉴和支持。
[Abstract]:With the rapid development of urbanization at home and abroad, the density of urban buildings is increasing. In the downtown construction and development project, the developer will stick the red line of the building to make use of the underground space as far as possible. What kind of formwork system should be adopted by the construction management, and the safety of the unilateral formwork should be ensured, which should be attached great importance to in the construction project management. Wangfujing International Brand Project, the outer line of the outer protection structure of the basement of Wangfujing International Brand Project is only 2 meters from the red line of the building, and there are 1.2 meters of slope protection piles and corresponding watertight curtains between the envelope structure and the red line of the building. The main thickness of exterior wall is 800mm, and the outer wall of basement is self-adhesive waterproof material. Therefore, the wall formwork of the basement enclosure structure can only choose the single side supporting formwork system. This paper takes Wangfujing International Brands Center Project as an example to study the concrete single side supporting formwork system from the point of view of construction. The contents include: 1, the application and development of the formwork construction technology in our country. Combined with Wangfujing international brand engineering example, according to the engineering characteristics, the design and selection of concrete unilateral formwork system for the wall of the outer protection structure in the basement and the construction technology are studied. In this paper, the whole process construction technical problems, such as formwork, support and step by step concrete construction, are discussed in detail. According to the construction technology, the strength of concrete monolateral formwork support system of outer basement envelope structure is discussed. Stiffness and stability are checked. The strength, stiffness and overall stability of the single-side formwork support system are ensured. From the technical point of view, the safety of the single-side support formwork system is ensured. This paper discusses the quality standard, quality assurance and safety and civilized construction guarantee measures of the single side supporting formwork system in construction management, and summarizes the construction effect of the unilateral formwork support system. Through the research, a set of methods and management control measures for the single side formwork system of the wall wall of the concrete basement outer enclosure structure are summarized, which can be used for reference and support for the construction of similar projects.
