A new type of prefabricated composite joint mainly includes fasteners, steel beams, steel columns, high-strength bolts, pre-embedded thin-walled steel plates, pre-embedded parts, and butt welds. First of all, the steel beam and steel column are connected by fasteners and high-strength bolts to improve the rotation capacity of the combined joint, so that the structure can better form the compression arch effect and play the role of catenary under the action of impact load, and improve the seismic capacity of the structure and progressive collapse resistance. Secondly, the shear bolts pre-embedded in the mid-span of the prefabricated slab connect the steel beam and the precast concrete slab to improve the shear resistance of the joint. Furthermore, the embedded parts pre-embedded at both ends of the plates can be connected by butt welds, so that two adjacent plates are connected to resist the negative bending moment of the structural support and improve the integrity of the structure. The prefabricated combined node of the invention realizes factory production, rapid assembly on site, avoids concrete pouring on site, improves construction efficiency, and reduces environmental pollution.
Description
技术领域technical field
本发明属于工程结构技术领域，具体涉及一种新型预制装配式组合节点。The invention belongs to the technical field of engineering structures, and in particular relates to a novel prefabricated assembly type combined node.
背景技术Background technique
钢与混凝土组合节点具有承载能力高、刚度大和抗震性能优越等优点，因此在装配式结构中应用广泛。而目前组合结构大都采用全焊接刚性连接，不仅现场施工速度慢、作业量高、对环境污染严重、焊缝质量难以控制，而且结构的转动能力和滞回性能差、延性低、抗震能力差。端板螺栓连接的半刚性组合节点具有更好的转动能力和滞回性能，能在地震动或冲击荷载作用下展现出更为的力学性能，能够有效的发挥组合梁的压拱效应及悬链线作用从而有着更好的抗连续倒塌性能，而且施工简便无污染。另外组合节点结构体系中的混凝土板施工时，通常采用现场浇筑，不仅对环境造成污染、施工效率慢，而且施工难度较大，设计复杂。因此寻求一种抗震性能好、施工效率高、建筑材料可回收利用的新型装配式组合节点，提高结构的抗震性能及抗连续倒塌能力的问题亟待解决。Steel and concrete composite joints have the advantages of high bearing capacity, high rigidity and superior seismic performance, so they are widely used in prefabricated structures. At present, most of the combined structures adopt all-welded rigid connections. Not only are the site construction speeds slow, the workload is high, the environmental pollution is serious, and the quality of the welds is difficult to control, but the structure has poor rotation capacity and hysteresis performance, low ductility, and poor earthquake resistance. The semi-rigid composite joints connected by end plate bolts have better rotation capacity and hysteresis performance, and can show better mechanical properties under the action of ground vibration or impact load, and can effectively play the compression arch effect of composite beams and catenary The line effect has better anti-successive collapse performance, and the construction is simple and pollution-free. In addition, when the concrete slabs in the combined node structure system are constructed, they are usually poured on site, which not only causes pollution to the environment, but also slows down the construction efficiency, and the construction is difficult and the design is complicated. Therefore, it is urgent to seek a new type of prefabricated composite joint with good seismic performance, high construction efficiency, and recyclable building materials to improve the seismic performance of the structure and the ability to resist progressive collapse.
