【摘要】：当前,我国的模板技术呈现出多样化、标准化、商品化的发展趋势,其中铝合金模板技术作为新型模板技术,在房建工程中已经取得了较好的应用效果,但新技术的推广需要质量标准做支撑,否则会受到劣质产品的冲击而影响推广。为促进铝合金模板质量体系的形成,为推广应用新材料、新技术,实现绿色施工,本文对铝合金模板施工进行了系统性的研究,主要开展了以下工作：1.对铝合金模板支撑体系即早拆体系,进行理论研究。使用ADINA有限元软件建立模型,分析了铝合金模板的受力情况以及拆模后混凝土实体的应力分布,结果表明：拆模后混凝土结构的最大应力将出现在板上部靠近支撑杆边线、向梁一侧,以及梁下部与板相接处；为确保施工安全,在遇大梁时,应在梁两侧加设支撑；层高增加时,需相应增加杆件的惯性矩。2.系统性研究了铝合金模板施工过程,包括铝合金模板的应用范围、模板加工进场、现场拼装施工、细部做法以及安全、质量保证措施,主要得到以下结论：铝合金模板适用于标准层数较多的超高层结构以及结构够形状简单、工期紧,有创优要求的结构；加工铝模时需严格控制原材料质量,项目部宜派技术人员进场协助加工；模板不宜一次性出厂,以便在施工过程中不断优化；拆除后的模板及时维护、校正变形。3.使用PDCA的质量控制方法,分析了影响铝合金模板混凝土成型质量的主要因素,并提出了相应的解决措施,对措施实施的效果进行了检查,结果表明：混凝土坍落度、振捣方法、模板的清理维护等是造成混凝土表面麻面、气泡的主要因素；严格控制模板加工尺寸偏差、尽量将坍落度控制在160mm左右、对新模板使用前行预氧化处理等措施有利于提高混凝土成型质量。论文从理论和应用两方面对铝合金模板施工进行了系统性研究,过程中自主研制了铝合金模板拆除杆,成功申报国家实用新型专利；在某在建项目成立QC小组,获得全国工程质量管理小组二等奖；同时,对铝合金模板施工过程的研究成果已成功申报四川省省级工法。取得的成果已表明,本文的研究对指导铝合金模板施工、推广铝合金模板应用具有很强的实际意义,且有助于铝合金模板质量体系的形成。
[Abstract]:At present, the formwork technology of our country presents the development trend of diversification, standardization and commercialization. The aluminum alloy formwork technology, as a new formwork technology, has already obtained the better application effect in the house construction project. But the popularization of the new technology needs the support of the quality standard, otherwise it will be affected by the impact of inferior products. In order to promote the formation of aluminum alloy formwork quality system and to popularize the application of new materials and technologies to realize green construction, this paper has carried out systematic research on aluminum alloy formwork construction, mainly carried out the following work: 1. The aluminum alloy formwork bracing system, that is, the early dismantling system, is studied theoretically. The finite element software Adina is used to establish the model, and the stress distribution of the concrete body after removing the aluminum alloy formwork is analyzed. The results show that the maximum stress of the concrete structure will appear in the upper part of the slab near the side line of the bracing bar. In order to ensure the safety of construction, support should be added on both sides of the beam, and the moment of inertia of the member should be increased accordingly when the height of the layer increases. This paper systematically studies the construction process of aluminum alloy formwork, including the application scope of aluminum alloy formwork, formwork approach, site assembling construction, detail method and safety and quality assurance measures. The main conclusions are as follows: aluminum alloy formwork is suitable for super-tall structures with more standard layers and structures with simple shape, tight construction period and excellent requirements, and the quality of raw materials should be strictly controlled when processing aluminum dies. Project department should send technical personnel to assist in processing; formwork should not be out of the factory at one time, in order to continue to optimize in the construction process; removed template timely maintenance, correction deformation. 3. Using the quality control method of PDCA, the main factors affecting the forming quality of aluminum alloy formwork concrete are analyzed, and the corresponding solving measures are put forward, and the effect of the measures is checked. The results show that the concrete slump and vibrating method are obtained. The cleaning and maintenance of the formwork are the main factors that cause the surface of concrete surface and bubble, strictly control the size deviation of the template processing, and try to control the slump around 160mm, The pre-oxidation treatment of new formwork is helpful to improve the quality of concrete forming. In this paper, the aluminum alloy formwork construction is studied systematically from the aspects of theory and application. In the process, the aluminum alloy formwork dismantling rod is developed independently, and the national utility model patent is successfully declared, and a QC group is set up in a certain project under construction. At the same time, the research results of aluminum alloy formwork construction process have been successfully applied to the provincial engineering method of Sichuan province. The results obtained show that the research in this paper has a strong practical significance for guiding the construction of aluminum alloy formwork and popularizing the application of aluminum alloy formwork, and is helpful to the formation of quality system of aluminum alloy formwork.
