specific Embodiment approach 1
[0026] Embodiment 1: Combining Figure 1-Figure 11 Illustrating this embodiment, the opening anti-buckling shear wall with buckling restraint fishplate includes an upper frame beam 9 , a lower frame beam 10 , a left frame column 11 , a right frame column 12 and a plurality of plates 15 , it also includes two buckling restraint fishplates 1 and two opening steel plates 8; the upper frame beam 9, the lower frame beam 10, the left frame column 11 and the right frame column 12 form a rectangular frame, and two buckling restraint fishtails The plate 1 is vertically installed in the rectangular frame, and the two opening steel plates 8 are symmetrically arranged in the rectangular frame. Each plate body 15 is fixedly connected to the inner side wall of the rectangular frame. In this embodiment, the plate body 15 is a fish plate body.
specific Embodiment approach 2
[0027] Specific implementation mode 2: Combining figure 1 and Figure 11 Illustrating this embodiment, the opening anti-buckling shear wall with buckling restraint fishplate described in this embodiment, the buckling restraint fishplate 1 includes a core steel plate 2, an upper connecting support 4, a lower connecting support 5 and two Two double-limb restraint steel pipes 3; the inner core steel plate 2 is welded and installed on an opening steel plate 8; On the bottom end of the beam 9 , the lower connecting support 5 is welded and installed on the top end of the lower frame beam 10 . The inner core steel plate 2 is placed in the opening steel plate 8 flush with the edge of the opening, and the edge of the opening steel plate 8 extends a length of the thickness of the opening steel plate 8 compared with the inner core steel plate 2. Connected by long fillet welds. Other compositions and connection methods are the same as those in the first embodiment.
specific Embodiment approach 3
[0028] Specific implementation three: combination figure 1 , Figure 5 , Image 6 and Figure 11 Describing this embodiment, in the opening anti-buckling shear wall with buckling restraint fishplate described in this embodiment, the upper connecting support 4 includes a first upper connecting plate 4-1 and a second upper connecting plate 4-2; The first upper connecting plate 4-1 and the second upper connecting plate 4-2 are both machined with elliptical pin shaft holes, and the first upper connecting plate 4-1 and the second upper connecting plate 4-2 are welded and installed on the upper frame beam 9 On the bottom end, the inner core steel plate 2 and the opening steel plate 8 are installed between the first upper connecting plate 4-1 and the second upper connecting plate 4-2. There is a gap between the top of the double-limb restraint steel pipe 3 and the upper connecting support 4 , and the width of the gap is greater than 1 / 20 of the width of the inner core steel plate ...
