Description
技术领域technical field
本实用新型涉及一种装配式钢-混凝土组合框架结构,属于结构工程领域。The utility model relates to an assembled steel-concrete composite frame structure, which belongs to the field of structural engineering.
背景技术Background technique
目前常用的建筑结构体系以建造材料可划分为分:钢筋混凝土结构、钢-混凝土组合结构、钢结构三类。钢筋混凝土结构是指用配有钢筋增强的混凝土制成的结构,承重的主要构件是用钢筋混凝土建造的,钢筋承受拉力,混凝土承受压力;钢-混凝土组合结构是钢部件和混凝土或钢筋混凝土部件组合成为整体而共同工作的一种结构,兼具钢结构和钢筋混凝土结构的一些特性;钢结构是由钢制材料组成的结构,主要由型钢和钢板等制成的钢梁、钢柱、钢桁架等构件组成。前两类体系施工时现场湿作业量大、工业化程度低;而钢结构为全工厂加工、现场安装,工业化程度较高。近年来,为促进建筑行业转型升级,建立节能减排、低碳环保型产业,我国鼓励推进装配式建筑的发展,推进建筑工业化,以此带动整个建筑产业化的发展。At present, the commonly used building structure system can be divided into three types based on construction materials: reinforced concrete structure, steel-concrete composite structure, and steel structure. Reinforced concrete structure refers to a structure made of concrete reinforced with steel bars. The main load-bearing components are constructed of reinforced concrete. The steel bars bear tension and the concrete bears pressure; steel-concrete composite structures are steel parts and concrete or reinforced concrete parts A structure that is combined into a whole and works together, and has some characteristics of steel structures and reinforced concrete structures; steel structures are structures composed of steel materials, mainly steel beams, steel columns, steel beams, steel columns, and steel structures made of steel and steel plates Composed of trusses and other components. During the construction of the first two types of systems, there is a large amount of on-site wet work and a low degree of industrialization; while the steel structure is processed in the whole factory and installed on site, with a high degree of industrialization. In recent years, in order to promote the transformation and upgrading of the construction industry and establish an energy-saving, emission-reducing, low-carbon and environmentally-friendly industry, my country has encouraged the development of prefabricated buildings and promoted the industrialization of construction, so as to drive the development of the entire construction industrialization.
预制装配式结构是工业化大生产的产物,同时有施工节奏快,产品质量好、预算造价低,施工效率高,生产工艺简单等优势。预制装配式构件易于生产和维护,经济效益很高,利用范围广泛,符合我国当前的建筑产业化发展趋势。钢框架可以很好的实现结构的预制装配化,同时具有建筑空间大、布置灵活等特点,但对于高层建筑结构,钢框架柱的抗侧刚度显得相对不足。钢-混凝土组合柱可以有效提高结构的抗侧刚度,并具有较好的经济效益,但传统的钢-混凝土组合柱需要立模板、支撑、养护、拆模等一系列繁琐的工艺流程,且不能与钢框架梁同步装配施工,造成施工工期长,造价高于普通混凝土结构等问题,背离工业化建筑快速、经济的核心,这就制约了钢-混凝土组合结构在装配式建筑中的应用。The prefabricated structure is the product of industrialized mass production, and has the advantages of fast construction pace, good product quality, low budget cost, high construction efficiency, and simple production process. Prefabricated components are easy to produce and maintain, have high economic benefits, and have a wide range of applications, which is in line with the current development trend of my country's construction industrialization. The steel frame can realize the prefabrication of the structure very well, and has the characteristics of large building space and flexible layout. However, for high-rise building structures, the lateral stiffness of steel frame columns is relatively insufficient. Steel-concrete composite columns can effectively improve the lateral stiffness of the structure and have good economic benefits, but traditional steel-concrete composite columns require a series of cumbersome processes such as formwork, support, maintenance, and formwork removal, and cannot Simultaneous assembly and construction with steel frame beams, resulting in long construction period and higher cost than ordinary concrete structures, deviates from the core of fast and economical industrial buildings, which restricts the application of steel-concrete composite structures in prefabricated buildings.

本实用新型提供的装配式钢-混凝土组合框架结构,包括预制钢-混凝土组合柱、预制钢梁、梁柱节点拼接装置。预制钢-混凝土组合柱的闭合钢骨架对核心混凝土施加侧向约束,使其处于三向受压的应力状态,从而比现有单面受压的组合柱提高约2倍的承载能力,。同时由于预制钢-混凝土组合柱的横断面为矩形,立面上缀板之间存在一定的间距,这就有效的解决了梁柱节点的连接问题。钢骨架是劲性承重骨架,在施工阶段它可起劲性骨架的作用,其焊接工作可以通过工厂机械化实现,从而可大大减少现场焊接量,提高工作效率。本实用新型的装配式钢-混凝土组合框架结构可拆卸,便于运输。现场连接主要采用高强螺栓,减少了现场的湿作业,提高了工作效率,高强螺栓的使用提高了结构在地震中的耗能性能。The assembled steel-concrete composite frame structure provided by the utility model includes a prefabricated steel-concrete composite column, a prefabricated steel beam, and a beam-column node splicing device. The closed steel skeleton of the prefabricated steel-concrete composite column imposes lateral constraints on the core concrete, making it in a stress state of three-way compression, thereby increasing the bearing capacity by about 2 times compared with the existing composite column under single-sided compression. At the same time, because the cross-section of the prefabricated steel-concrete composite column is rectangular, there is a certain distance between the panels on the facade, which effectively solves the connection problem of the beam-column joints. The steel skeleton is a rigid load-bearing skeleton, which can act as a rigid skeleton during the construction stage, and its welding work can be realized through factory mechanization, which can greatly reduce the amount of on-site welding and improve work efficiency. The assembled steel-concrete composite frame structure of the utility model is detachable and convenient for transportation. The on-site connection mainly uses high-strength bolts, which reduces the wet work on site and improves work efficiency. The use of high-strength bolts improves the energy dissipation performance of the structure in earthquakes.
