Embodiment 1
[0039] like figure 1 , 3, 4, the steel plate core tube is built in the bottom double-lapped steel concrete frame of the present invention, and the core tube is composed of a steel-concrete laminated frame column, a soft steel energy-dissipating steel plate 2 and surrounding shear wall panels. A shear wall steel plate 3 is arranged in the force wall panel, and a steel mesh composed of horizontally distributed steel bars 4 and longitudinally distributed steel bars 5 is arranged in the shear wall wall panels on both sides of the shear wall steel plate 3. Between the steel mesh The steel bars 6 are used to pull and connect each other; the steel-concrete laminated frame columns are set at both ends of the shear wall panels, that is, at the intersection of the shear wall panels, and are connected with the middle shear wall steel plate 3 as a whole; the steel-concrete laminated A mild steel energy-dissipating steel plate 2 is superimposed on the outside of the bottom of the section ...
Embodiment 2
[0048] Another structural form of steel plate core tube with built-in steel-concrete frame at the bottom and its method is as follows: figure 2 , image 3 and Figure 4 As shown, its frame column is a circular cross-section steel pipe concrete column, and other structural forms and manufacturing methods are basically the same as in Embodiment 1.
Embodiment 3
[0050] Other structural forms such as the steel plate core tube and the method of double-lapped steel-concrete frames at the bottom Figure 5-Figure 10 As shown, the frame columns are respectively circular or rectangular in cross-section, and the section steel 1 is I-beam, round steel pipe or square steel pipe respectively, and other structural forms and manufacturing methods are basically the same as in Embodiment 1.
