Embodiment 1
[0033] Schematic diagram of structural reinforcement of a structural unit of CFST frame-steel truss-concrete composite shear wall figure 1 , figure 2 and image 3shown. There is no reinforcement in the frame column 3 of concrete-filled steel tube; the frame beam of the shear wall is a steel beam 4 with longitudinal reinforcement 7 arranged around it, and rectangular stirrups 8 are evenly bound along the longitudinal reinforcement 7 of the beam, and the rectangular stirrups 8 of the frame beam are evenly distributed to Beam end; the reinforcement of the shear wall panel is: the horizontal reinforcement 5 and the vertical reinforcement 6 of the shear wall panel are evenly arranged on both sides of the width direction of the wall panel along the horizontal and vertical directions, and are bound and fixed at the intersection points to form Two pieces of steel mesh, the two ends of the horizontal steel bar 5 and the vertical steel bar 6 are respectively inserted into the steel p...
Embodiment 2
[0044] The second structural form of CFST frame-steel truss-concrete composite shear wall is as follows Figure 4 As shown, the X-shaped hidden steel support 2 and the hidden steel support 9 are arranged on the inner side of the two pieces of steel mesh in the shear wall panel, and the upper end extends into the joint between the frame column and the upper frame beam, and is connected with the concrete filled steel pipe frame column 3 and the upper frame. The beams are medium-sized steel beams with 4 connections. The lower end extends into the node of the frame column and the lower frame beam, and is connected with the steel tube concrete frame column 3 and the lower frame beam medium-sized steel beam 4 . Other aspects are the same as the first form.
Embodiment 3
[0046] The third structural form of CFST frame-steel truss-concrete composite shear wall is as follows: Figure 5 As shown, the eight-shaped steel concealed support 2 and the reinforced steel concealed support 9 are arranged on the inside of the two pieces of steel mesh in the shear wall panel. Among the nodes of the frame beam, it is connected with the steel pipe concrete frame column 3 and the medium-sized steel beam 4 of the lower frame beam. Other aspects are the same as the first form.
