Abstract
Description
技术领域technical field
本发明属于预制混凝土剪力墙装配式技术领域，涉及一种预制混凝土剪力墙装配式连接节点。The invention belongs to the technical field of prefabricated concrete shear wall assembly, and relates to a prefabricated concrete shear wall assembly connection node.
背景技术Background technique
预制装配式建筑是一种在工厂生产预制梁、板、柱和墙等建筑构件，经过养护并验收合格后运输至现场安装施工完成的建筑方式。装配式建筑具有建筑构件标准化设计，工厂化加工，装配式施工的特点，有利于降低施工造成的环境污染，缩短施工周期，节约人力物力。Prefabricated building is a construction method in which prefabricated beams, slabs, columns, walls and other building components are produced in the factory, and after maintenance and acceptance, they are transported to the site for installation and construction. The prefabricated building has the characteristics of standardized design of building components, factory processing, and prefabricated construction, which is conducive to reducing environmental pollution caused by construction, shortening the construction period, and saving manpower and material resources.
在建筑结构中，剪力墙主要承受风荷载或地震作用引起的水平荷载和竖向荷载。在装配式混凝土结构中，剪力墙水平连接主要采用灌浆套筒连接技术，预制剪力墙内埋灌浆套筒，现场安装后注入灌浆料完成墙体之间的连接。但在实际应用中，灌浆套筒连接技术存在诸多缺点，一是预制混凝土剪力墙配筋量大，施工时套筒与钢筋对接难度大；二是套筒灌浆密实度检测困难，容易出现漏浆和夹空现象，施工质量难以保证；三是套筒工艺复杂、造价高昂，增加装配式混凝土建筑整体造价。专利CN107460969A公开一种新型预制混凝土剪力墙的装配方法，该种连接方式取消了灌浆套筒，施工质量可得到保证，但施工时现场仍需绑扎钢筋浇筑混凝土，现场作业量大；专利CN207079756U公开一种干式连接混凝土剪力墙与墙干式连接方法，该方法采用现场无需灌浆的干作业方式，但施工过程中钢筋与套筒之间仍存在大量对接问题，施工难度大。In building structures, shear walls mainly bear horizontal and vertical loads caused by wind loads or earthquakes. In the prefabricated concrete structure, the horizontal connection of the shear wall mainly adopts the grouting sleeve connection technology. The grouting sleeve is embedded in the prefabricated shear wall, and the grouting material is injected after the on-site installation to complete the connection between the walls. However, in practical application, there are many shortcomings in the grouting sleeve connection technology. First, the precast concrete shear wall has a large amount of reinforcement, and it is difficult to connect the sleeve and the steel bar during construction; The phenomenon of slurry and voids makes it difficult to guarantee the construction quality; the third is that the sleeve process is complicated and the cost is high, which increases the overall cost of the prefabricated concrete building. Patent CN107460969A discloses a new type of assembly method for prefabricated concrete shear walls. This connection method eliminates the grouting sleeve, and the construction quality can be guaranteed. However, it is still necessary to bind steel bars and pour concrete on site during construction, and the site workload is large; patent CN207079756U discloses A dry connection method for concrete shear walls and walls. This method adopts a dry operation method that does not require grouting on site. However, there are still a lot of docking problems between steel bars and sleeves during the construction process, and the construction is difficult.
