Problems solved by technology
The hydraulic damper uses the viscous resistance of the hydraulic oil to achieve shock absorption. Its shock absorption effect is good, but the structure is complicated, the processing precision of the piston and the cylinder is high, and the production cost is high. The anti-leakage measures in the working chamber must be effective for a long time , the maintenance cost is high, and the piston rod is prone to shear damage to the working chamber after being subjected to non-axial force, resulting in oil leakage and permanent damage, so this structure is not suitable for simply supported beam bridges and continuous beam bridges

Embodiment Construction
[0022] figure 1 A schematic structural view of the steel damping device of the present invention is shown. As shown in the figure, the steel damping anti-seismic device includes a corrugated steel cylinder 1 , and connectors 2 are provided at both ends of the corrugated steel cylinder 1 . The corrugated steel cylinder 1 is wavy along its axial direction, that is, the generatrix of the corrugated steel cylinder 1 is a wavy line, which can be a sinusoidal curve or formed by alternately connecting circular arc-shaped convex and concave lines. Arc wavy line, the generatrix of corrugated steel cylinder 1 adopts arc wavy line in the present invention. The corrugated steel cylinder has a certain resistance to damping. Under the action of external force, the corrugated steel cylinder produces tensile and compressive deformation. Compared with the mild steel damper, it has the advantage of hysteresis energy consumption. Greater energy, better shock resistance and shock absorption.

The invention discloses a steel damping anti-shock device. The steel damping anti-shock device comprises a waveform steel cylinder and connection pieces located at the two ends of the waveform steel cylinder respectively. The steel damping anti-shock device has the following advantages that (1) the steel damping anti-shock device is structurally composed of the waveform steel cylinder and the connection pieces located at the two ends of the waveform steel cylinder; compared with a hydraulic damper, the structure is simple and the production and maintenance cost is low; (2) under the action of an external force, the waveform steel cylinder has expansion-compression deformation; compared with a soft steel damper, the steel damping anti-shock device has the advantage of capability of realizing back-and-forth hysteresis energy dissipation; under the condition that the size is the same, greater energy can be absorbed, and anti-shock and shock-absorption effects are better; (3) compared with the hydraulic damper and the soft steel damper, the size of wave ripples of the waveform steel cylinder can be adjusted, and energy adsorption and energy consumption effects can be changed through adjusting the size of the wave ripples, so that the applicability is greater.
Description
technical field [0001] The invention relates to an anti-seismic device, in particular to an anti-seismic device of a steel structure. Background technique [0002] Existing anti-seismic damping devices are generally mild steel dampers and hydraulic dampers. [0003] For example, the invention patent application document with the publication number CN104196145A discloses an energy-dissipating and shock-absorbing damper component for an earthquake-resistant building, including a main structure and an energy-dissipating device; the energy-dissipating device includes a damper component, an embedded part, and a splint; The device components include connecting plates and dampers. Among them, the damper, which is the key component of seismic resistance, is a shear type mild steel damper. During earthquake or wind vibration, the energy input into the structure is dissipated through the plastic yield hysteretic deformation of mild steel, so as to achieve the purpose of shock absorpt...
