Description

一种采用栓钉连接的预制装配式钢-混凝土组合梁A prefabricated steel-concrete composite beam connected by studs

背景技术 Background technique

我国于20世纪50年代起开始实现建筑工业化的应用,借鉴前苏联的技术体系,在工业厂房和住宅中推广发展预制构件和预制装配式建筑。到20世纪80年代,预制混凝土构件一度取得良好的研究成果和发展趋势,但是限于当时的经济条件和技术水平,预制装配式建筑没有得到大规模推广使用。在20世纪90年代以后,由于廉价劳动力大量出现,商品混凝土技术发展等原因,预制装配式建筑在民用建筑中应用不断减少,发展进入了低谷期。而近年来,随着国内经济持续高速增长,劳动力成本不断提高,节能环保的意识成为主流,我国在预制装配式建筑结构上的研究和应用也逐渐增多,国家出台的许多相关政策法规鼓励企业推广使用预制装配式建筑,这都使得建筑工业化迈向一个新的阶段。 my country began to realize the application of construction industrialization in the 1950s, drawing on the technical system of the former Soviet Union, and promoting the development of prefabricated components and prefabricated buildings in industrial plants and residences. By the 1980s, prefabricated concrete components had achieved good research results and development trends, but limited to the economic conditions and technical level at that time, prefabricated buildings have not been widely used. After the 1990s, due to the emergence of a large number of cheap labor and the development of commercial concrete technology, the application of prefabricated buildings in civil buildings continued to decrease, and the development entered a low period. In recent years, as the domestic economy continues to grow at a high speed, labor costs continue to increase, and awareness of energy conservation and environmental protection has become the mainstream, the research and application of prefabricated building structures in my country has gradually increased. Many relevant policies and regulations issued by the state encourage enterprises to promote The use of prefabricated buildings has brought the industrialization of construction to a new stage.

在预制装配式建筑结构中,预制装配式钢-混凝土组合结构占有越来越重要的地位。其与预制装配式混凝土结构相比,可以减轻自重,减小地震作用,缩短施工周期,增加结构延性等,与钢结构相比,可以减小用钢量,增大结构刚度,稳定性和整体性等。 In prefabricated building structures, prefabricated steel-concrete composite structures occupy an increasingly important position. Compared with the prefabricated concrete structure, it can reduce the self-weight, reduce the earthquake effect, shorten the construction period, increase the structural ductility, etc. Compared with the steel structure, it can reduce the steel consumption, increase the structural rigidity, stability and overall sex etc.

预制装配式钢-混凝土组合梁是一种新型组合梁构造形式,其中H型钢梁和钢筋混凝土板均为预制构件,可以快速连接装配,组成整体结构。预制装配式混凝土楼板与H型钢梁的连接构件施工速度较快且构件制作质量较高,可以有效节约资源和能源,提高材料在实现建筑节能和结构性能方面的作用,减少了建筑垃圾对于环境的影响和施工现场对于场地环境需求,提高建筑功能和结构性能,符合我国建筑行业绿色发展要求,能促进达成预定的节能减排目标。 Prefabricated steel-concrete composite beam is a new type of composite beam structure, in which H-shaped steel beams and reinforced concrete slabs are prefabricated components, which can be quickly connected and assembled to form an overall structure. The connection components of prefabricated concrete floor slabs and H-shaped steel beams have a faster construction speed and higher component production quality, which can effectively save resources and energy, improve the role of materials in achieving building energy conservation and structural performance, and reduce construction waste for the environment. The influence of the construction site and the environmental requirements of the site, improve the building function and structural performance, meet the green development requirements of my country's construction industry, and can promote the achievement of the predetermined energy saving and emission reduction goals.

传统的混凝土楼板与H型钢梁的连接构造以及现浇钢筋混凝土与梁的连接构造施工难度较大,施工工序复杂,材料用量多,施工质量不稳定,建筑全周期能耗高。因此研制一种预制装配式钢-混凝土组合梁来克服传统的混凝土楼板与H型钢梁的连接构造以及现浇钢筋混凝土与梁的连接构造的缺点,具有重要意义和价值。 The traditional connection structure between concrete floor slab and H-shaped steel beam and the connection structure between cast-in-place reinforced concrete and beam are relatively difficult to construct, the construction process is complicated, the amount of materials is large, the construction quality is unstable, and the energy consumption of the whole building cycle is high. Therefore, it is of great significance and value to develop a prefabricated assembled steel-concrete composite beam to overcome the shortcomings of the traditional connection structure between the concrete floor and the H-shaped steel beam and the connection structure between the cast-in-place reinforced concrete and the beam.
