Embodiment Construction

[0027] The patent of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0028] Figure 1, figure 2 As shown, the energy-dissipating damping sheet for reducing the vibration of the cantilevered glass curtain wall of the patent of the present invention is referred to as the energy-dissipating damping sheet, which includes steel plate A1, steel plate B2 and the high-damping viscoelastic material layer 3 sandwiched therein, steel plate A1, steel plate B2 is a vertical rectangular long plate, the length should be greater than 5 meters, preferably greater than 10 meters, and the thickness is about 0.5cm to 5cm. There are multiple protective steel clips 4 between the steel plates, which are hook plates, and the plate body is fixed or The connecting piece is connected to the edge of the steel plate A1, and the hook is hooked on the back of the steel plate B2, only allowing the relative displacement between th...

Abstract

The invention relates to an energy-consumption damping sheet which can reduce the vibration of span or suspension structure (as vertical suspension, horizontal suspension and incline suspension. Wherein, two sides of high damped visco-elastic material layer 3 are adhered with steel plate A and steel plate B (or several combined layers between steel plate and visco-elastic material layer); the steel plate A and steel plate B are upright rectangle plate, with a protective steel clamper 4 between them; the protective steel clamper 4 is a hook plate fixed or via connector on the edge of steel plate A or B; the hook hooks the back of steel plate B or A; the steel plate A via connector 5 is connected to the structural element; the connector 5 is formed by the U-shaped connector 51 connecting the element and the reversed U-shaped connector 52 connecting the steel plate A, while their sections are in positive or reversed U shape that clamping each other; the clamp edge of U-shaped connector 51 is folded inwards and the connecting edge is folded outwards; the clamping edge of reversed U-shaped connector 52 is made into slide rod 521 in post shape.

Description

technical field [0001] The invention relates to the fields of structural engineering and structural vibration control, and relates to a control device for reducing structural vibration of large spans or overhangs (including vertical overhangs, horizontal overhangs, and oblique overhangs)—an energy-dissipating damping sheet. Background technique [0002] Structural vibration control is a new way to reduce structural vibration (such as earthquake resistance and wind resistance) that has emerged in recent decades. Through the unremitting efforts of researchers at home and abroad, structural vibration control has made great progress in both theoretical research and engineering application. As a passively controlled energy dissipation control device, its control strategy is to use non-load-bearing energy dissipation components to consume energy first, so as to reduce the vibration response of the main structure and protect the main structure. The 3M company of the United States ...
