  • Patent number: 11401712
    Abstract: The present invention belongs to the technical field of energy consumption and vibration reduction of assembled building structures, and provides an energy-consuming connecting device for a prefabricated assembled wall. The present invention provides a normal connection function between walls, and also has the functions of energy consumption and vibration reduction. A used viscoelastic material can provide energy consumption and weaken the cold and hot bridge effect, which is beneficial to building thermal insulation. Meanwhile, the energy-consuming connecting device for the prefabricated assembled wall can be connected with a prefabricated wall in advance, which can be carried out at the same time as the wall is inserted during construction, thereby effectively increasing the construction efficiency. Through the design of clamping groove devices, the wall can be connected firmly and reliably while generating displacement and consuming energy.

  • Patent number: 11293415
    Abstract: The present invention belongs to the technical field of structural vibration control, and provides a composite axial energy consumption device based on piezoelectricity and shape memory alloy, comprising a screw, steel pipes, stiffening ribs, steel sheets, bolt-nuts, piezoceramics, screw caps and SMA wire bundles. The mechanical energy of the structure under pressure is converted into the electric energy of the piezoceramics and then the electric energy is converted into heat energy, so that energy consumption efficiency is high and mechanical performance is good. The SMA wire bundles have large tensile bearing capacity, shape memory effect and good corrosion resistance and fatigue resistance. The number of the segments and the specifications of the piezoceramics and the SMA wire bundles can be adjusted according to the actual needs, so that the structure can be adjusted according to the size of an axial force and specific stress conditions.

  • Patent number: 11248389
    Abstract: An inertial mass amplification type tuned mass damper is disclosed. The inertial mass amplification type tuned mass damper comprises a hollow box, an H-shaped mass block, gears a, gears b, a rectangular frame, a steel ring, viscous dampers, a steel sheet, springs, rotating shafts and balls. In the present invention, an inertial damping force is amplified by adjusting the radius ratio of the gears a and the gears b; and damping parameters can be conveniently changed by adjusting the mass of the mass block, the spring stiffness and the like. The present invention has the advantages that the design mass is small, which can avoid the adverse effects of excessive additional gravity on the structure and improve the performance of the structure. The present invention has reasonable design and small occupied space, can save more use area for buildings and can greatly improve the utilization efficiency of the buildings.

  • Publication number: 20210148434
    Abstract: The present invention discloses a coupling beam eddy current damper with shear displacement amplification. The coupling beam eddy current damper with shear displacement amplification comprises a rigid rod, rotating shafts, a pin column, pins, levers, screws, thread sleeves, copper sheets, permanent magnet components, a steel structural component, balls, ball supports and an outer shell. When vibration occurs, coupling beams on both sides of the damper are relatively vertically displaced; at this moment, two levers move up and down relative to the rigid rod; the movement causes the screws and the copper sheets to rotate; the copper sheets rotate in a magnetic field, then induced electromotive force will generates inside the magnetic field, thereby generating eddy current in the copper sheets. The eddy current effect will produce a damping force that impedes the rotation of the copper sheets.
