Description
技术领域technical field
本发明涉及预制装配式混凝土建筑结构领域,特别是涉及一种预制装配式混凝土框架。The invention relates to the field of prefabricated assembled concrete building structures, in particular to a prefabricated assembled concrete frame.
背景技术Background technique
随着我国进入经济结构转型升级的关键阶段,大力发展预制装配式建筑已经是大势所趋。装配式建筑是用预制部品部件在工地装配而成的建筑。发展装配式建筑是建造方式的重大变革,是推进建筑业供给侧结构性改革的重要举措,有利于节约资源能源、减少施工污染、提升劳动生产效率和质量安全水平,有利于促进建筑业与信息化工业化深度融合、培育新产业新动能、推动化解过剩产能。As my country enters a critical stage of economic structural transformation and upgrading, it is the general trend to vigorously develop prefabricated buildings. Prefabricated buildings are buildings assembled on site with prefabricated parts. The development of prefabricated buildings is a major change in the construction method and an important measure to promote the supply-side structural reform of the construction industry. It is conducive to saving resources and energy, reducing construction pollution, improving labor production efficiency and quality and safety levels, and promoting the construction industry and information. The deep integration of chemical industrialization, the cultivation of new industries and new kinetic energy, and the promotion of the resolution of excess capacity.
预制装配式混凝土框架结构因其具有平面布置灵活、室内空间大等优点而成为世界范围内使用最为广泛的预制装配式混凝土结构体系之一。目前,普通预制装配式混凝土框架结构通常采用二次现浇的施工方法,即于施工现场在梁柱节点处后浇混凝土的方法使得各预制梁、柱构件形成整体结构。这种施工方法大大拖慢了施工效率,违反了采用预制装配式结构的初衷;在梁柱节点区由于钢筋绑扎较多,存在钢筋无法准确放置的现象,施工工人往往采取乱砍钢筋、乱放钢筋的手段,这是一个极大的安全隐患;在现场浇注的混凝土,由于节点区空间狭小,可能会存在混凝土振捣不足,养护不佳的现象,施工质量难得得到保证。由此可见,传统的采用二次现浇施工方法的预制装配式混凝土框架结构体系是一种效率低下、存在安全隐患、质量无法保证的的结构体系。Prefabricated concrete frame structure has become one of the most widely used prefabricated concrete structural systems in the world because of its advantages of flexible layout and large indoor space. At present, ordinary prefabricated concrete frame structures usually adopt the construction method of secondary cast-in-place, that is, the method of post-casting concrete at the beam-column joints on the construction site to make the prefabricated beam and column components form an integral structure. This construction method greatly slows down the construction efficiency and violates the original intention of adopting the prefabricated assembly structure; in the beam-column joint area, due to the fact that there are many steel bars bound, there is a phenomenon that the steel bars cannot be placed accurately. The means of steel bars is a great safety hazard; the concrete poured on site may have insufficient concrete vibration and poor maintenance due to the small space in the node area, and the construction quality is rarely guaranteed. It can be seen that the traditional prefabricated concrete frame structure system using the secondary cast-in-place construction method is a structural system with low efficiency, potential safety hazards, and unguaranteed quality.
历次大地震的震害调查资料显示,预制装配式混凝土框架结构在地震中破坏严重。其破坏严重的主要原因是二次现浇区与预制构件的连接处抗震性能较差,整体性不强。由于预制构件与二次现浇区的施工质量难以保证,往往导致预制装配式混凝土框架结构连接处的性能差,直接劣化了整体结构的抗震性能与整体性,因此施工简便、质量保障度高,且性能可靠的连接方式对预制装配式混凝土结构至关重要。The earthquake damage investigation data of previous major earthquakes show that the prefabricated concrete frame structure was seriously damaged in the earthquake. The main reason for its serious damage is that the joint between the secondary cast-in-place area and the prefabricated components has poor seismic performance and poor integrity. Since the construction quality of the prefabricated components and the secondary cast-in-place area is difficult to guarantee, the performance of the joints of the prefabricated concrete frame structure is often poor, which directly deteriorates the seismic performance and integrity of the overall structure. Therefore, the construction is simple and the quality assurance is high. And a reliable connection method is very important for prefabricated concrete structures.
