Description
技术领域technical field
本发明属于建筑技术领域,特别是涉及一种装配式混凝土嵌入式预制柱与预制阳台。The invention belongs to the technical field of buildings, in particular to an assembled concrete embedded prefabricated column and a prefabricated balcony.
背景技术Background technique
装配式混凝土建筑的发展始于20世纪50年代,经过了研究、迅速发展、使用和发展缓慢等阶段,于2000年以后,国家发展低碳经济时,装配式混凝土建筑以其能源消耗低、建造速度快与环境污染少等特点,逐步迈向了一个新的发展阶段。并且,在2010年,在首都相继推出了《关于产业化住宅项目实施面积奖励等优惠措施的暂行办法》和《关于推进本市住宅产业化的指导意见》,有效的指导装配式住宅项目的实施。并且,国家许多行业协会、设计院所和住建部门逐步展开有关装配式技术的研究工作,纷纷出台了《整体预应力装配式板柱建筑技术规程》、《叠合板用预应力混凝土底板》和《装配整体式住宅混凝土构件制作、施工及验收验收规范》等标准规范,有效的助推了相关行业的发展。此后,2016年,国家进一步加强了对装配式建筑的应用,计划在未来10年,让该建筑应用比例占建筑比例的30%左右。由此可见,在国家政府的支持下,装配式混凝土建筑具有良好的发展前景。The development of prefabricated concrete buildings began in the 1950s. After research, rapid development, use and slow development, after 2000, when the country developed a low-carbon economy, prefabricated concrete buildings were characterized by low energy consumption and low construction costs. With the characteristics of fast speed and less environmental pollution, it has gradually entered a new stage of development. Moreover, in 2010, the "Interim Measures on the Implementation of Area Incentives and Other Preferential Measures for Industrialized Housing Projects" and "Guiding Opinions on Promoting the Industrialization of Housing in this City" were successively launched in the capital to effectively guide the implementation of prefabricated housing projects . Moreover, many industry associations, design institutes and housing construction departments in the country have gradually carried out research work on prefabricated technology, and have issued "Technical Regulations for Integral Prestressed Prefabricated Slab-Column Buildings", "Prestressed Concrete Floor for Laminated Slabs" and Standards and regulations such as the "Code for Fabrication, Construction and Acceptance of Prefabricated Integral Residential Concrete Components" have effectively boosted the development of related industries. Since then, in 2016, the country has further strengthened the application of prefabricated buildings, and plans to make the proportion of this building application account for about 30% of the building proportion in the next 10 years. It can be seen that with the support of the national government, prefabricated concrete buildings have good development prospects.
装配式建筑注重对环境、资源的保护,其施工过程中有效减少了建筑污水、有害气体、粉尘的排放和建筑噪音的污染,降低了建筑施工对周边环境的各种影响,有利于提高建筑的劳动生产率,促进设计、建筑的精细化,提升建筑的整体质量和节能减排水率,促进了我国建筑业健康可持续发展,符合国家经济发展的需求。The prefabricated building pays attention to the protection of the environment and resources. During the construction process, it effectively reduces the emission of construction sewage, harmful gases, dust and construction noise pollution, reduces the various impacts of construction on the surrounding environment, and is conducive to improving the construction efficiency. Labor productivity promotes the refinement of design and construction, improves the overall quality of buildings and the rate of energy conservation and drainage reduction, promotes the healthy and sustainable development of my country's construction industry, and meets the needs of national economic development.
在大力推动转变经济发展方式,调整产业结构和大力推动节能减排工作的背景下,北京、上海、沈阳、深圳、济南、合肥等城市地方政府以保障性住房建设为抓手,陆续出台支持建筑工业化发展的地方政策。国内的大型房地产开发企业、总承包企业和预制构件生产企业也纷纷行动起来,加大建筑工业化投入。从全国来看,以新型预制混凝土装配式结构快速发展为代表的建筑工业化进入了新一轮的高速发展期。这个时期是我国住宅产业真正进入全面推进的时期,工业化进程也在逐渐加快推进,但是总体来看与发达国家相比差距还很大。随着我国的建筑设计和建造技术的逐渐进步,设计的内容也从最初单一的形式考虑转变成在形式、功能与环保等各方之间寻求平衡,而预制装配系统几乎可以满足多种类型的建筑。实际上,装配式建筑早在几十年前便已初现。近年来,随着国内外双重需求压力的不断增加,装配式建筑形式再次被提出并应用。目前,上海已有一些企业在住宅类工程中采用了装配式建筑。Under the background of vigorously promoting the transformation of economic development mode, adjusting industrial structure and vigorously promoting energy conservation and emission reduction, the local governments of Beijing, Shanghai, Shenyang, Shenzhen, Jinan, Hefei and other cities focus on the construction of affordable housing and have successively issued policies to support buildings. Local policies for industrial development. Domestic large-scale real estate development companies, general contracting companies and prefabricated component manufacturers have also taken action to increase investment in construction industrialization. From a national perspective, the construction industrialization represented by the rapid development of new prefabricated concrete assembly structures has entered a new round of rapid development. This period is a period when my country's housing industry is truly advancing in an all-round way, and the process of industrialization is also gradually accelerating, but overall there is still a big gap compared with developed countries. With the gradual progress of my country's architectural design and construction technology, the content of the design has also changed from the initial consideration of a single form to a balance between form, function and environmental protection, and the prefabricated assembly system can almost meet various types. architecture. In fact, prefabricated buildings have emerged as early as decades ago. In recent years, with the increasing pressure of dual demand at home and abroad, prefabricated building forms have been proposed and applied again. At present, some enterprises in Shanghai have adopted prefabricated buildings in residential projects.
北美地区主要以美国和加拿大为主.由于预制/预应力混凝土协会(PCI)长期研究与推广预制建筑,预制混凝土的相关标准规范也很完善.所以其装配式混凝土建筑应用非常普遍。北美的预制建筑主要包括建筑预制外墙和结构预制构件两大系列。预制构件的共同特点是大型化和预应力相结合.可优化结构配筋和连接构造,减少制作和安装工作量,缩短施工工期,充分体现工业化、标准化和技术经济性特征。在20世纪,北美的预制建筑主要用于低层非抗震设防地区。由于加州地区的地震影响,近年来非常重视抗震和中高层预制结构的工程应用技术研究。PCI最近出版了《预制混凝土结构抗震设计》一书,从理论和实践角度系统地分析了预制建筑的抗震设计问题,总结了许多预制结构抗震设计的最新科研成果,对指导预制结构设计和工程应用推广具有很强的指导意义。North America is mainly dominated by the United States and Canada. Due to the long-term research and promotion of precast buildings by the Precast/Prestressed Concrete Association (PCI), the relevant standards and specifications for precast concrete are also very complete. Therefore, its prefabricated concrete building application is very common. Prefabricated buildings in North America mainly include two series of building prefabricated exterior walls and structural prefabricated components. The common feature of prefabricated components is the combination of large-scale and prestress. It can optimize the structural reinforcement and connection structure, reduce the workload of fabrication and installation, shorten the construction period, and fully reflect the characteristics of industrialization, standardization and technical economy. In the 20th century, prefabricated buildings in North America were mainly used in low-rise non-seismic fortified areas. Due to the impact of earthquakes in the California area, in recent years, great attention has been paid to the research on engineering application technology of earthquake resistance and mid-high-rise prefabricated structures. PCI recently published the book "Seismic Design of Prefabricated Concrete Structures", which systematically analyzes the seismic design of prefabricated buildings from the perspective of theory and practice, and summarizes the latest scientific research achievements in the seismic design of prefabricated structures. Promotion has a strong guiding significance.
欧洲是预制建筑的发源地,早在17世纪就开始了建筑工业化之路。第二次世界大战后,由于劳动力资源短缺,欧洲更进一步研究探索建筑工业化模式。无论是经济发达的北欧、西欧,还是经济欠发达的东欧,一直都在积极推行预制装配混凝土建筑的设计施工方式。积累了许多预制建筑的设计施工经验,形成了各种专用预制建筑体系和标准化的通用预制产品系列,并编制了一系列预制混凝土工程标准和应用手册,对推动预制混凝土在全世界的应用起到了非常重要的作用。Europe is the birthplace of prefabricated buildings, and the road to industrialization of buildings began as early as the 17th century. After the Second World War, due to the shortage of labor resources, Europe further studied and explored the industrialization model of construction. Whether it is economically developed Northern Europe, Western Europe, or economically underdeveloped Eastern Europe, they have been actively promoting the design and construction of prefabricated concrete buildings. Accumulated a lot of experience in the design and construction of prefabricated buildings, formed various special prefabricated building systems and standardized general prefabricated product series, and compiled a series of precast concrete engineering standards and application manuals, which played a role in promoting the application of precast concrete in the world very important role.
日本和韩国借鉴了欧美的成功经验,在探索预制建筑的标准化设计施工基础上,结合自身要求,在预制结构体系整体性抗震和隔震设计方面取得了突破性进展。具有代表性成就的是日本2008年采用预制装配框架结构建成的两栋58层的东京塔。同时,日本的预制混凝土建筑体系设计、制作和施工的标准规范也很完善,目前使用的预制规范有《预制混凝土工程}(JASSl0)和《混凝土幕墙)(JASSl4)。Drawing on the successful experience of Europe and the United States, Japan and South Korea have made breakthroughs in the overall seismic and isolation design of prefabricated structural systems on the basis of exploring the standardized design and construction of prefabricated buildings and combining their own requirements. Representative achievements are the two 58-story Tokyo Towers built in Japan in 2008 using prefabricated frame structures. At the same time, the standard specifications for the design, production and construction of precast concrete building systems in Japan are also very complete. The prefabricated specifications currently in use include "Precast Concrete Engineering" (JASSl0) and "Concrete Curtain Wall) (JASSl4).
装配式混凝土建筑和采用预制空心楼板的砌体建筑成为两种最主要的建筑体系,应用普及率达70%以上。由于装配式建筑的功能和物理性能存在许多局限和不足,我国的装配式混凝土建筑设计和施工技术研发水平还跟不上社会需求及建筑技术发展的变化。到20世纪90年代中期,装配式混凝土建筑已逐渐被全现浇混凝土建筑体系取代,目前除装配式单层工业厂房建筑体系应用较广泛外,其他预制装配式建筑体系的工程应用极少。预制结构抗震的整体性和设计施工管理的专业化研究不够,造成其技术经济性较差。这是导致预制结构长期处于停滞状态的根本原因。Prefabricated concrete buildings and masonry buildings with prefabricated hollow-core slabs have become the two most important building systems, with an application penetration rate of over 70%. Due to the many limitations and deficiencies in the functions and physical properties of prefabricated buildings, my country's prefabricated concrete building design and construction technology research and development level cannot keep up with social needs and changes in the development of construction technology. By the mid-1990s, prefabricated concrete buildings had been gradually replaced by all-cast-in-place concrete building systems. At present, except for prefabricated single-storey industrial plant building systems, other prefabricated building systems are rarely used in engineering applications. Insufficient research on the anti-seismic integrity of prefabricated structures and professional design and construction management results in poor technical and economic efficiency. This is the root cause of the long-term stagnation of prefabricated structures.
预应力薄板叠合楼板1940~1942年间,英国P.W.埃伯利斯首先创议把下部用预应力薄板作为模板与上部现浇混凝土组成一个整体。40年代末到50年代初,英国、苏联、瑞士、瑞典、法国、波兰、奥地利等国都开始采用这类楼板。60~70年代迅速发展,特别是法国和联邦德国目前已广泛应用在各类房屋建筑中。中国于1980年进行试制。经过多种跨度和不同荷载的结构试验,1981年在北京27层高的西苑饭店工程首次采用,面积约2万平方米。此后,在一些高层旅游宾馆、办公楼、外交公寓、仓库等工程中,得到推广。Between 1940 and 1942, British P.W. Eberlis first proposed to use the prestressed thin slab as a formwork in the lower part and form a whole with the cast-in-place concrete in the upper part. From the late 1940s to the early 1950s, Britain, the Soviet Union, Switzerland, Sweden, France, Poland, Austria and other countries began to adopt this type of floor. It developed rapidly in the 1960s and 1970s, especially in France and the Federal Republic of Germany, and has been widely used in various housing constructions. Trial production was carried out in China in 1980. After structural tests with various spans and different loads, it was first used in the 27-storey Xiyuan Hotel project in Beijing in 1981, with an area of about 20,000 square meters. Since then, it has been promoted in some high-rise tourist hotels, office buildings, diplomatic apartments, warehouses and other projects.
从国内外的研究和应用经验来看,可采用预制装配式框架结构、预制装配式剪力墙结构、预制装配式框架-现浇剪力墙(核心筒)结构体系。结构中承重构件可以全部为预制构件或者预制与现浇构件相结合。其中,预制装配式剪力墙结构可以分为全预制剪力墙结构、部分预制剪力墙结构和适当降低结构性能要求的多层剪力墙结构。预制装配式框架结构及预制装配式框架-现浇剪力墙(核心筒)结构中的框架,梁、柱全部采用预制构件,承重构件之间的节点、拼缝连接均按照等同现浇结构要求进行设计和施工。该结构体系具有和现浇结构等同的性能,结构的适用高度、抗震等级与设计方法与现浇结构基本相同。全预制剪力墙结构指全部剪力墙采用预制构件拼装装配。预制墙体之间的拼缝基本等同于现浇结构或者略低于现浇结构,需要通过设计计算满足拼缝的承载力、变形要求,并在整体结构分析中考虑拼缝的影响。该结构体系的预制化率高,但拼缝的连接构造比较复杂、施工难度较大,难以保证完全等同于现浇剪力墙结构,目前的研究和工程实践还不充分,在震区的推广应用还需要进一步的研究工作。From the research and application experience at home and abroad, prefabricated frame structure, prefabricated shear wall structure, prefabricated frame-cast-in-place shear wall (core tube) structure system can be used. The load-bearing components in the structure can be all prefabricated components or a combination of prefabricated and cast-in-place components. Among them, the prefabricated assembly shear wall structure can be divided into fully prefabricated shear wall structure, partial prefabricated shear wall structure and multi-layer shear wall structure with appropriately reduced structural performance requirements. Prefabricated assembled frame structure and prefabricated assembled frame-cast-in-place shear wall (core tube) frame, beams and columns are all prefabricated components, and the joints and joints between load-bearing components are in accordance with the requirements of the same cast-in-place structure design and construction. The structural system has the same performance as the cast-in-place structure, and the applicable height, seismic level and design method of the structure are basically the same as the cast-in-place structure. Fully prefabricated shear wall structure means that all shear walls are assembled and assembled with prefabricated components. The joints between the prefabricated walls are basically equal to or slightly lower than the cast-in-place structures. It is necessary to meet the bearing capacity and deformation requirements of the joints through design calculations, and consider the impact of the joints in the overall structural analysis. The prefabrication rate of this structural system is high, but the connection structure of the joints is relatively complicated, and the construction is difficult. It is difficult to ensure that it is completely equivalent to the cast-in-place shear wall structure. The current research and engineering practice are not sufficient. The promotion in the earthquake zone Applications require further research work.
