Modularized steel structure connecting joint

OU JINPING / YANG CHAO / WANG XIAOGUANG / ZHANG ZONGJUN / ZHAO BAOJUN

The modularized steel structure connecting joint comprises an upper module column, an upper module beam, a lower module column and a lower module beam, wherein inner partition plates are welded to the inner wall of the upper module column and the inner wall of the lower module column; the connecting piece comprises a connecting plate and an inner cylinder; and grouting materials. The arrangement of the inner partition plates can transmit tension and pressure of the upper and lower flanges of the module beam to avoid tearing of the column wall, and can prevent the inner cylinder from being pulled out due to tension. And on the other hand, due to the fact that the contact area between the inner cylinder and the grouting material is large, higher tensile and flexural bearing capacity can be provided. Therefore, according to the possible stress form of the actual work of the modular structure, the designed joint can achieve the purposes of simple structure, reasonable force transmission and reliable connection. According to the modular steel structure connecting joint, an independent outer cylinder does not need to be manufactured, and by designing a reasonable grouting path, construction is fast and convenient, all decoration of the modules in a factory is not affected, and the assembly production efficiency of the modules is greatly improved.

一种模块化钢结构连接节点包括：上模块柱、上模块梁、下模块柱和下模块梁，上模块柱和下模块柱的内壁均焊接有内隔板；连接件，包括连接板和内筒；灌浆料。内隔板的设置，一方面可以传递模块梁上下翼缘的拉压力，避免柱壁撕裂，另一方面能防止内筒受拉被拔出。内筒在绕柱轴线扭矩作用下的抗扭能力强，另一方面由于其与灌浆料接触面积大，能提供更高的抗拉和抗弯承载力。因此，根据模块化结构实际工作可能的受力形式，设计的该节点能达到构造简单、传力合理与连接可靠的目的。本申请提供的模块化钢结构连接节点，无需制造单独的外筒，通过设计合理的灌浆路径，达到施工快捷方便，不影响模块在工厂实现全部装修，模块的组装生产效率大幅提升。
