AI Technical Summary
Existing metal shear dampers require stiffening ribs to ensure structural strength, resulting in poor performance. Furthermore, their damping performance is fixed, failing to exhibit different stiffness and energy dissipation characteristics at different load stages, making it difficult to meet the damping requirements of different earthquake intensities.
A double-stage metal shear damper without stiffeners was designed. The displacement of the first-stage metal plate drives the snap-fit block to move, which pushes the baffle and sleeve to swing along the fixed rod, so that energy is transferred to the second-stage metal plate. Combined with the torsion spring reset mechanism and the pressure sensor controller alarm system, the damping adaptability under different earthquake intensities can be achieved.
It achieves timely response and vibration reduction under different earthquake intensities. The snap-fit block ensures the baffle fits and transmits energy in a timely manner. The second-order metal plate provides force-assisted vibration reduction and provides timely alarm when the structure is damaged, thus improving the vibration reduction effect and safety.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0022] Referring to Figures 1-4 A double-stage metal shear type damper without stiffening ribs, comprising two connecting plates 1 and a first-stage metal plate 2, the first-stage metal plate 2 being fixedly connected at the gap between the two connecting plates 1, a plurality of connecting frames 3 being fixedly connected to the corresponding sides of the two connecting plates 1, the corresponding sides of the plurality of connecting frames 3 being fixedly connected with a second-stage metal plate 4 at the same time, a plurality of sliding blocks 5 and clamping blocks 6 being fixedly connected to the side wall of the first-stage metal plate 2, a plurality of sliding grooves being formed in the inner wall of the second-stage metal plate 4, the plurality of sliding blocks 5 being slidingly arranged in the inner walls of the plurality of sliding grooves, a notch being formed in the inner wall of the second-stage metal plate 4 at the center, the clamping block 6 being slidingly arranged in the inner wall of the notch, a fixed rod 7 being fixedly connected to the inner wall of the notch of the second-stage metal plate 4, a sleeve 8 being movably sleeved on the rod wall of the fixed rod 7, a baffle 9 and a clamping plate 10 being fixedly connected to the cylinder wall of the sleeve 8, and a clamping hole being formed in the side wall of the clamping block 6 and matched with the clamping plate 10.
[0023] A torsion spring 11 is sleeved on the wall of the fixed rod 7. One end of the torsion spring 11 is fixedly connected to the inner wall of the sleeve 8, and the other end of the torsion spring 11 is fixedly connected to the inner wall of the second-order metal plate 4.

One end of the wire 14 away from the pressure sensor 13 is electrically connected to the controller 12.
[0025] In use, the first-stage metal plate 2 and the second-stage metal plate 4 can be installed in the designated positions through the connecting plate 1 and the connecting frame 3, which can meet the shear damping effect and ensure the normal use of the metal shear damper. When the load is too large and causes the first-stage metal plate 2 to deviate to a certain extent, it will drive the slider 5 and the locking block 6 to move.

[0028] To achieve the effect of eliminating the need for stiffening ribs, such as Figures 1-4 As shown, the snap-fit block 6 is inclined on the inner wall of the snap-fit opening, the side wall of the baffle 9 is in contact with the side wall of the snap-fit block 6, the two sides of the first-stage metal plate 2 are respectively provided with outwardly protruding inclined surfaces, and the connecting plate 1 and the connecting frame 3 are respectively provided with multiple threaded connection holes.
