Description
技术领域Technical field
本发明涉及一种预制板与剪力墙连接结构及施工方法。The invention relates to a prefabricated panel and shear wall connection structure and a construction method.
背景技术Background technique
采用预制装配式结构能够节能、节水、节材，大幅度减少建筑垃圾、降低噪声污染，减少劳动力用量和强度，有效改善施工环境，提高工程质量，因此受到了研究者和工程设计人员的青睐，是值得大力推广的结构。在装配式结构中，接缝连接技术是关键技术，是保证结构整体性和抗震性能的关键。The use of prefabricated structures can save energy, water, and materials, significantly reduce construction waste, reduce noise pollution, reduce labor usage and intensity, effectively improve the construction environment, and improve project quality, so it is favored by researchers and engineering designers. , is a structure worthy of vigorous promotion. In prefabricated structures, seam connection technology is a key technology and is the key to ensuring structural integrity and seismic performance.
预制装配式剪力墙结构目前具有较多的工程应用，当前剪力墙与楼板之间的连接主要是通过现浇的方式，楼板大多采用叠合板，预制部分搁置在剪力墙上，钢筋延伸入剪力墙，后浇混凝土形成一个整体，这种方式混凝土浇筑量大，预制率低，仍有很大的现场湿作业，现场还要绑扎现浇部分的钢筋，不能充分发挥装配式的优点。Prefabricated shear wall structures currently have many engineering applications. The current connection between shear walls and floor slabs is mainly through in-situ casting. Most of the floor slabs use composite panels, and the prefabricated parts are placed on the shear walls, and the steel bars are extended. The shear wall is inserted into the shear wall, and the concrete is poured later to form a whole. This method requires a large amount of concrete pouring, a low prefabrication rate, and there is still a lot of on-site wet work. The cast-in-place steel bars must be tied on site, which cannot give full play to the advantages of the prefabricated type. .
楼板与剪力墙连接部位是受力的关键部分，现有叠合板在端部受力较大，施工中如果在端部加强只能通过配置较多的钢筋来实现，如果在原有不增加钢筋的情况下，其端部往往容易在受力中发生破坏。The connection between the floor slab and the shear wall is the key part to bear stress. The existing laminated slabs bear greater stress at the ends. If the ends are strengthened during construction, they can only be achieved by configuring more steel bars. If no steel bars are added to the original In such cases, the ends are often easily damaged during stress.
剪力墙与楼板形成整体后，下剪力墙与上剪力墙的连接目前大多是通过套筒灌浆的方式，上剪力墙搁置在楼板上，因此需要等待楼板达到一定强度才能开始施工，上剪力墙的钢筋套筒套在下剪力墙延伸出来的钢筋，通过密封条和套筒灌浆方式来连接，这种方式形式单一，现场施工质量影响大，不好控制，施工麻烦；而且剪力墙的连接并不是所有钢筋都连接，而除了边缘构件外一定间距仅有单个钢筋连接，这种连接形式不够可靠，抗震性能和延性都不够理想。部分学者也提出了一些上下预制剪力墙的连接方式，但是大多没有考虑楼板的安装，不切合实际。After the shear wall and the floor are integrated, the connection between the lower shear wall and the upper shear wall is currently mostly done by sleeve grouting. The upper shear wall rests on the floor, so it is necessary to wait for the floor to reach a certain strength before construction can begin. The steel sleeves of the upper shear wall are placed on the steel bars extending from the lower shear wall, and are connected through sealing strips and sleeve grouting. This method is single in form, has a great impact on the quality of on-site construction, is difficult to control, and is troublesome to construct; and shearing The connection of the force wall does not connect all the steel bars, but only a single steel bar is connected at a certain distance except the edge components. This connection form is not reliable enough, and the seismic performance and ductility are not ideal enough. Some scholars have also proposed some ways to connect upper and lower precast shear walls, but most of them do not consider the installation of floor slabs, which is not practical.
