[0021] Specific implementation mode two: combination Image 6 with Figure 8 The present embodiment will be described. The spherical cap 5 of the present embodiment is welded by two spherical shells 5-1. When the spherical cap 5 and the small ball 6 are assembled, the small ball 6 is first placed in the center of the two spherical shells 5-1, and then the two spherical shells 5-1 are aligned, and then welded through with a butt weld. In this way, the small ball 6 is constrained by the spherical cap 5, and only relative rotation can occur between the small ball 6 and the spherical cap 5, and no relative displacement can occur. Other components and connections are the same as those in the first embodiment.

Abstract

A fully articulated column end joint, which involves a beam-column connection member, in order to solve the traditional beam-column connection using rigid connection, excessive residual deformation occurs after a large or moderate earthquake, thereby increasing the cost of post-earthquake maintenance and reconstruction question. The upper column in the node area and the lower column in the node area are set up and down, the spherical surface of the spherical cap is set in the semicircular groove of the lower web and the semicircular groove of the reinforcing rib in the lower column, and the lower end of the ball is set in the spherical crown Inside, the upper end of the ball is set in the inner hole of the hollow inverted pyramid truss, and the four beams are respectively located on the four sides of the lower column in the node area, and the upper flange of each beam is aligned with the upper end of the hollow inverted pyramid truss Flat, the upper flange of each beam is connected to the upper column in the joint area through angle steel and connecting elements, the lower flange of each beam is flush with the upper end face of the lower column in the joint area, and the lower flange of each beam is connected by angle steel And the connecting element is connected with the lower column of the junction area. The invention is used in anti-lateral force components in the field of building structure engineering.

Description

technical field [0001] The invention relates to a beam-column connection component, in particular to a fully-articulated column end node. Background technique [0002] Earthquake disasters have had a great impact on people's lives, mainly due to excessive damage or collapse of building structures during earthquakes. By setting the support in the structure, the lateral stiffness of the structure can be effectively improved while reducing the deformation of the structure. However, the traditional beam-to-column connection adopts rigid connection. Under the action of load, the maximum bending moment of the column is located at the end of the column. This effect will increase the stress of the column and weaken the elastic deformation capacity of the main frame, resulting in a large residual deformation or even collapse. In order to reduce the stress of the column, the column stress can be reduced by enlarging the section of the column, but this will undoubtedly increase the m...
