装配式框架的钢盒箱体连接器Steel Box Box Connectors for Fabricated Frames

技术领域technical field

本发明属于预制装配式混凝土构件结构技术领域,特别是涉及一种装配式框架的钢盒箱体连接器。The invention belongs to the technical field of prefabricated assembled concrete member structures, in particular to a steel box box connector of an assembled frame.

背景技术Background technique

装配式混凝土建筑是指以工厂化生产的混凝土预制构件为主.通过现场装配的方式设计建造的混凝土结构类房屋建筑。构件的装配方法一般有现场后浇叠合层混凝土、钢筋锚固后浇混凝土连接等,钢筋连接可采用套筒灌浆连接、焊接、机械连接及预留孔洞搭接连接等做法。20世纪80年代,在我国流行的装配式预制大板住宅,由于结构整体性差、渗漏、楼板裂缝等原因,存在许多影响结构安全及正常使用的隐患和缺陷,逐渐被现浇混凝土结构所取代。但随着当前新兴的装配式混凝土结构的应用,特别是近年来引进了许多国外先进技术,本土化的装配式混凝土结构建造新技术正逐步形成。Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, and were gradually replaced by cast-in-place concrete structures. . However, with the current emerging application of prefabricated concrete structures, especially the introduction of many foreign advanced technologies in recent years, localized new technologies for the construction of prefabricated concrete structures are gradually forming.

装配式钢筋混凝土结构是我国建筑结构发展的重要方向之一,它有利于我国建筑工业化的发展,提高生产效率节约能源,发展绿色环保建筑,并且有利于提高和保证建筑工程质量。与现浇施工工法相比,装配式RC结构有利于绿色施工,因为装配式施工更能符合绿色施工的节地、节能、节材、节水和环境保护等要求,降低对环境的负面影响,包括降低噪音、防止扬尘、减少环境污染、清洁运输、减少场地干扰、节约水、电、材料等资源和能源,遵循可持续发展的原则。而且,装配式结构可以连续地按顺序完成工程的多个或全部工序,从而减少进场的工程机械种类和数量,消除工序衔接的停闲时间,实现立体交叉作业,减少施工人员,从而提高工效、降低物料消耗、减少环境污染,为绿色施工提供保障。另外,装配式结构在较大程度上减少建筑垃圾(约占城市垃圾总量的30%―40%),如废钢筋、废铁丝、废竹木材、废弃混凝土等。Prefabricated reinforced concrete structure is one of the important directions for the development of my country's building structure. It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated RC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment. Including reducing noise, preventing dust, reducing environmental pollution, clean transportation, reducing site disturbance, saving water, electricity, materials and other resources and energy, and following the principles of sustainable development. Moreover, the prefabricated structure can continuously complete multiple or all processes of the project in sequence, thereby reducing the types and quantities of construction machinery entering the site, eliminating the idle time between process connections, realizing three-dimensional cross operations, reducing construction personnel, and improving work efficiency , Reduce material consumption, reduce environmental pollution, and provide guarantee for green construction. In addition, the prefabricated structure can reduce construction waste to a large extent (accounting for about 30%-40% of the total urban waste), such as waste steel bars, waste iron wires, waste bamboo wood, waste concrete, etc.

虽然装配整体式框架结构有诸多的好处,但是在实际施工过程中连接节点处存在着许多技术难题,吊装构件不易进行施工定位,进而降低施工质量和装配效率;对装配整体式框架结构而言,梁—柱连接又是施工关键所在,目前梁—柱连接的钢筋连接多采用机械套筒连接、焊接连接或湿式连接等形式;而这些连接节点又存在着构造复杂、传力不直接、施工工序较多等问题。这就需要开发新的便于连接的预制装配式钢筋混凝土框架梁柱连接节点,在满足承载力性能的前提下简化现场施工中节点的连接构造,方便现场操作,简化施工工艺,减少拼装时间。Although there are many advantages in assembling the integral frame structure, there are many technical difficulties at the connection nodes in the actual construction process, and the hoisting components are not easy to carry out construction positioning, thereby reducing the construction quality and assembly efficiency; for the assembly of the integral frame structure, The beam-column connection is the key to the construction. At present, the steel bar connection of the beam-column connection mostly adopts the form of mechanical sleeve connection, welding connection or wet connection. However, these connection nodes have complex structures, indirect force transmission, and construction procedures. More questions. This requires the development of new prefabricated reinforced concrete frame beam-to-column joints that are easy to connect. On the premise of meeting the bearing capacity performance, the connection structure of the joints in the on-site construction is simplified, the on-site operation is convenient, the construction process is simplified, and the assembly time is reduced.
