Description
技术领域：Technical field:
本实用新型涉及建筑结构连接件技术领域，具体涉及一种装配式预制混凝土剪力墙与钢梁连接的连接件。The utility model relates to the technical field of building structure connectors, in particular to a connector for connecting an assembled prefabricated concrete shear wall and a steel beam.
背景技术：Background technique:
随着新型城镇化进程不断推进，大力发展绿色建筑和推动建筑工业化已经成为当前建筑业发展的重要方向，钢结构由于材料强度高，可回收利用等优点，符合绿色、节能、环保的发展趋势。With the continuous advancement of the new urbanization process, vigorously developing green buildings and promoting construction industrialization have become an important direction for the development of the current construction industry. Due to the advantages of high material strength and recyclability, steel structures are in line with the development trend of green, energy saving and environmental protection.
钢框架结构具有空间大、结构布置灵活、抗震性能好、施工周期短、结构自重小、钢材可回收利用、易于改建和拆除等优点，是目前多高层建筑中应用最广泛的一种结构形式，但钢框架抗侧移刚度小，在罕遇地震作用下变形大，对节点的转动变形能力要求高。一种经济有效的方法是在钢框架结构中内填混凝土剪力墙，钢框架内填混凝土剪力墙结构能够提高钢框架的抗侧刚度，限制钢框架的变形，钢框架与混凝土剪力墙协同工作,充分发挥钢结构轻质高强和混凝土抗压性能好的特点，在受力过程中钢框架承担全部竖向荷载和大部分弯矩，混凝土剪力墙几乎承担全部水平剪力，能够提高结构的延性和耗能能力，可以有效的提高结构抗震性能，具有较好的经济效果。The steel frame structure has the advantages of large space, flexible structure layout, good seismic performance, short construction period, small structure weight, recyclable steel, easy reconstruction and demolition, etc. It is currently the most widely used structural form in multi-story buildings. However, the steel frame has low lateral displacement stiffness and large deformation under rare earthquakes, which requires high rotational deformation capacity of the joints. An economical and effective method is to fill the concrete shear wall in the steel frame structure. The concrete shear wall structure filled in the steel frame can improve the lateral stiffness of the steel frame and limit the deformation of the steel frame. The steel frame and the concrete shear wall Work together to give full play to the characteristics of light weight and high strength of steel structure and good compressive performance of concrete. During the stress process, the steel frame bears all the vertical load and most of the bending moment, and the concrete shear wall bears almost all the horizontal shear force, which can improve The ductility and energy dissipation capacity of the structure can effectively improve the seismic performance of the structure and have a good economic effect.
与内填现浇混凝土剪力墙相比，钢框架内填预制混凝土剪力墙结构体系易于拆分，有利于实现工业化生产。混凝土剪力墙与钢框架梁在工厂加工完成，现场与钢框架同步拼装，具有施工方便、施工速度快、减少现场湿作业、提高施工质量等优点。采用钢框架内填预制混凝土剪力墙结构的关键问题是如何保证预制混凝土剪力墙与钢框架梁之间的可靠连接，可靠地连接件能够有效的传递层间剪力、提高结构的承载力和抗侧刚度，因此在设计钢框架梁与预制混凝土剪力墙之间的连接件时，不仅要保证结构具有较好的整体工作性能，同时要求连接件具有传力简单，易于制作及施工。Compared with in-situ cast-in-place concrete shear walls, the structural system of precast concrete shear walls filled with steel frames is easy to disassemble, which is conducive to the realization of industrial production. Concrete shear walls and steel frame beams are processed in the factory and assembled with the steel frame synchronously on site, which has the advantages of convenient construction, fast construction speed, reduced on-site wet work, and improved construction quality. The key problem of using precast concrete shear wall structure filled with steel frame is how to ensure the reliable connection between the precast concrete shear wall and the steel frame beam. Reliable connectors can effectively transmit the interstory shear force and improve the bearing capacity of the structure. Therefore, when designing the connection between the steel frame beam and the precast concrete shear wall, it is necessary not only to ensure that the structure has good overall performance, but also to require the connection to be simple in force transmission and easy to manufacture and construct.
钢框架梁与预制混凝土剪力墙之间现有的连接形式主要为：栓钉和螺栓连接二种连接形式。栓钉连接主要是将抗剪栓钉与钢框架梁直接焊接在一起，在预制混凝土剪力墙处设置齿槽，采用齿槽吻合栓钉的方式连接，此种连接方式在齿槽与栓钉对接过程中精度要求较高，不利现场施工。现有螺栓连接主要为钢板式连接件，此种方式是将钢板连接件与钢梁焊接在一起，与预制混凝土剪力墙中的预埋钢板采用高强螺栓水平连接，此种连接方式需开设较多的螺栓孔，对加工、安装精度要求高，由于钢梁与剪力墙自重影响对水平向螺栓连接安装不利。The existing connection forms between steel frame beams and precast concrete shear walls are mainly two connection forms: stud connection and bolt connection. The stud connection is mainly to directly weld the shear studs and the steel frame beams together, set the alveolar at the precast concrete shear wall, and use the alveolar anastomosis studs to connect. The precision requirement in the docking process is high, which is not conducive to on-site construction. The existing bolt connections are mainly steel plate connectors. In this way, the steel plate connectors and steel beams are welded together, and the embedded steel plates in the precast concrete shear walls are connected horizontally with high-strength bolts. Many bolt holes require high processing and installation accuracy, and the installation of horizontal bolt connections is unfavorable due to the influence of the self-weight of steel beams and shear walls.
