Problems solved by technology

[0003] However, the existing toggle-type deformation amplification device is prone to out-of-plane instability, and under rare earthquakes, the structural deformation is relatively large, which may cause excessive damping force
However, when the out-of-plane instability of the device occurs, the relative displacement at both ends of the damper cannot reach the expected relative displacement, and the energy consumption of the damper is smaller than expected, resulting in the structure failing to meet the design performance target and severely damaged under rare earthquakes

Embodiment 1

[0034] Such as Figure 1-Figure 2 As shown, this embodiment provides a toggle-type deformation amplification device, which is connected in a frame composed of structural columns 1 and beams 2, and is used to amplify the displacement and velocity of the damper under wind loads and earthquakes. The device Including a deformation amplification assembly, the toggle is located above, which is an upper single toggle deformation amplification device. The deformation amplification assembly includes a gusset plate 3, an ear plate 4, a damper 5, a support mechanism, a cover plate 8 and an anti-instability plate 9. There are three gusset plates 3, which are welded and installed at the nodes of the frame. One end of the damper 5 and the two ends of the support mechanism are respectively connected to a gusset plate 3 through an ear plate 4, and the other end of the damper 5 is movably connected to the support mechanism. , the cover plate 8 and the anti-destabilization plate 9 are connected...

Embodiment 2

[0047] When the span-to-height ratio of the frame is greater than 2.5, a double-toggle deformation amplification device may be considered. The double-toggle deformation amplification device has little effect on the opening of the door, and its working principle is the same as that of Embodiment 1. Such as Figure 5 Shown is a central double-knuckle deformation amplification device. There are two deformation amplification components, which are symmetrically arranged in the frame. One end of the two supporting mechanisms is respectively connected to the same gusset plate installed on the beam 2 through an ear plate 4 3, at this moment, there are five gusset plates 3.

[0048] This embodiment can also adopt the eccentric double-knuckle deformation amplification device, such as Figure 6 As shown, there are two deformation amplification components, which are symmetrically arranged in the frame, and a gap is provided between the two deformation amplification components. At this ti...

Abstract

The invention relates to a toggle-type deformation amplifying device, which is connected in a frame composed of structural columns and beams, and is used to amplify the displacement and velocity of a damper under wind load and earthquake. The device includes at least one deformation amplifying component , the deformation amplification assembly includes a gusset plate, a damper and a support mechanism, and also includes an ear plate, a cover plate and an anti-stabilization plate, and the gusset plate is provided with at least three pieces, which are welded and installed on the node of the frame or on the beam, One end of the damper and two ends of the support mechanism are respectively movably connected to a gusset plate through an ear plate, the other end of the damper is movably connected to the support mechanism, and both the cover plate and the anti-instability plate are connected to the damper and the support Institutional connections. Compared with the prior art, the anti-instability plate of the present invention has greater bending stiffness outside the plane of the frame, and through the connection with the first support and the second support, it can effectively restrain the out-of-plane deformation of the device and prevent the plane of the device from being deformed. External instability.

Description

technical field [0001] The invention relates to a device for amplifying the energy consumption effect of a damper, in particular to a toggle-type deformation amplifying device for improving the efficiency of damping equipment for reducing wind vibration response and earthquake response in the field of civil engineering. Background technique [0002] The existing toggle-type deformation amplification device is composed of a damper, a support, and a connecting device (pin shaft, gusset plate, etc.). In the plane of the frame, one end of the damper and one end of the support are hinged to different beam-column nodes through the connecting device; the other end of the damper and the support are hinged at the same point through the connecting device. Under earthquake action and wind load, the interstory displacement of the structure occurs, and the deformation amplification device begins to function, and the relative displacement at both ends of the damper is greater than the int...
