Embodiment Construction
[0038] The present invention is described in detail below in conjunction with accompanying drawing:
[0039] as attached figure 1 As shown, in the post-earthquake self-resettable multi-section beam central support steel frame of the present invention, the involved special-shaped columns are: L-shaped column 1, T-shaped column 2, and cross-shaped column 3;
[0040] as attached figure 2 As shown, the post-earthquake self-resettable multi-section beam central support steel frame of the present invention mainly includes L-shaped, T-shaped, and cross-shaped joints. Taking the cross-shaped joints as an example in the figure, the ten The glyph node connection is that the cross-shaped column 3 is connected with the end I-beam 4 . Specific connection steps: the hoisting equipment makes the end I-beam 4 and the cross-shaped column 3 vertically and closely contacted, and the web angle steel 5 is used as a connecting piece to connect the end I-beam 4 and the cross-shaped column 3 with ...
