【摘要】：建筑幕墙具有良好的抵御风雨侵袭和潮湿空气渗透的能力,相较于传统围护结构,建筑幕墙还具有重量轻的特点,因而相较于传统围护结构减少了超高层建筑的地震作用。近年来,采用幕墙作为外观效果的高层及超高层建筑越来越多,而幕墙施工的难度也越来越高各构件的施工验算、施工安全管理等问题也越来越突出。本次研究以某超高广播电视多功能发射塔外幕墙悬挑式型钢施工平台的设计和搭设为研究对象进行施工验算、施工安全管理等方面的研究。超高层建筑不断刷新的建筑高度及日新月异的外立面表达对我国现有幕墙施工方式的现状提出了新的要求,随着建筑幕墙的广泛运用,其施工设计的问题也越来越突出。幕墙施工技术要求严格,施工难度较大,施工条件也受到多方面的制约。但是幕墙行业发展迅速,已经成为建筑行业的主流工程。在这种情况下,专业从幕墙施工的公司也如雨后春笋一般的出现,行业规模逐渐扩大开来,很多施工中的问题也就随之而出现。幕墙装饰公司的施工技术参差不齐,其中一些施工单位没能做施工方案设计以至在施工过程中出现了很多技术性问题。如何提高悬挑式施工操作平台的安全性,确保悬挑式施工操作平台的施工安全,已成为当前迫切需要解决的一项重要课题。本文在建筑幕墙工程实践中总结经验教训,从悬挑式施工操作平台的设计计算、搭设与拆除、架体结构细部处理、施工组织等方面来阐述幕墙工程的施工要点,经研究发现在施工方案的设计重点在于施工操作平台的设计计算及施工组织管理,特别是脚手架整体设计、型钢梁悬挑平台验算、吊篮安全验算、施工方案编制等方面要满足施工的要求。通过案例实证,按照以上施工程序,把握关键技术要点,使工程达到降低施工安全风险、保证施工工期、实现良好经济效益的目的,同时提高工程质量,满足技术规范要求并且通过幕墙工程检测。本文对超高广播电视多功能发射塔外幕墙工程悬挑式型钢施工平台的设计和搭设在施工设计、构件验算及施工方案编制等方面存在的潜在问题进行识别与分析,结合工程实践总结幕墙工程施工过程中的安全管理和控制措施,为日后超高广播电视多功能发射塔外幕墙施工平台的构件验算及施工方案编制提供参考和依据。
[Abstract]:Architectural curtain wall has a good ability to resist wind and rain attack and moist air infiltration. Compared with the traditional enclosure structure, building curtain wall also has the characteristics of light weight. In recent years, more and more high-rise and super high-rise buildings have been used to use curtain wall as the appearance effect. The construction of curtain wall is more and more difficult. The construction safety management and other problems are becoming more and more prominent. This study takes the design and erection of the cantilevered steel construction platform of a certain ultra-high radio and television multi-function transmitting tower outer curtain wall as the research object to carry out the construction checking calculation. Construction safety management and other aspects. The continuous renovation of the building height of super-high-rise buildings and the ever-changing expression of the facade put forward new requirements for the current situation of curtain wall construction in China. With the wide use of curtain wall, the construction design problem is more and more prominent. Curtain wall construction technology requirements are strict, construction difficult, construction conditions are also restricted by many aspects. But curtain wall industry is developing rapidly. Has become the mainstream of the construction industry. In this case, professional from curtain wall construction companies are also springing up in general, the industry scale gradually expanded. A lot of construction problems also appear. The construction technology of curtain wall decoration company is not uniform. Some of the construction units failed to design the construction scheme and even appeared a lot of technical problems in the construction process. How to improve the safety of the cantilevered construction operating platform. To ensure the construction safety of the cantilevered construction platform has become an urgent need to solve an important issue. This paper summarizes the experience and lessons in the construction curtain wall engineering practice. From the aspects of design and calculation of cantilever construction operation platform, erection and demolition, frame structure detail treatment, construction organization and so on, the construction essentials of curtain wall engineering are expounded. Through the study, it is found that the design emphasis of the construction scheme lies in the design calculation and construction organization management of the construction operation platform, especially the overall design of scaffold, the checking calculation of type steel beam cantilever platform, and the safety checking calculation of the hanging basket. Through the case study, according to the above construction procedure, we should grasp the key technical points, so as to reduce the construction safety risk and ensure the construction period. At the same time, the project quality is improved. Meet the requirements of the technical specifications and through the curtain wall engineering detection. The design and construction design of the cantilevered steel construction platform for the UHV multi-function transmitting tower external curtain wall engineering. The potential problems of component checking calculation and construction scheme are identified and analyzed, and the safety management and control measures in the construction process of curtain wall engineering are summarized in combination with engineering practice. It provides reference and basis for the component checking calculation and construction scheme compilation of the construction platform of the outer curtain wall of the super high radio and television multifunctional transmitting tower in the future.
