However, this type of damping device is not suitable for the reinforcement of beam-column joints of towering structures and angular displacement energy dissipation and vibration reduction.
[0004] The invention patent with the application publication number CN101713226A discloses a beam-column joint reinforcement arc-shaped viscoelastic damping device, which is composed of a sliding friction damping device and a viscoelastic damping device as a damping device suitable for energy dissipation and vibration reduction of beam-column joints. The damping device shown in the invention is arranged in an arc shape, which can be used for angular displacement vibration reduction and energy dissipation, but its structure is complicated, and it can only be used at beam-column joints with an included angle of 90 degrees, and is not suitable for high-rise structures. At the node of the main material with an acute angle

Embodiment 2
[0030] On the basis of the above-mentioned embodiments, the applicant found during the experiment that the main characteristics of the viscoelastic material layer are related to temperature. When the temperature is low to a certain extent, the viscoelastic material is in a glassy state and loses its damping properties; at high temperatures, It is in a rubber state, and the damping is also very small; only at medium frequency and medium temperature, the damping is the largest and the damping effect is the best. Therefore, the applicant has set up a temperature-adjustable The system includes a temperature sensor, a control device and a temperature adjustment device (not shown), the control device is connected with the detection device and the temperature adjustment device, the temperature adjustment device is installed on the restraint plate, and the temperature detection device detects the viscoelastic material The temperature of the layer and the data signal are transmitted to ...

The invention discloses a damping device suitable for a node joint of any included angle. The damping device comprises two restraining plates, a middle plate, viscoelastic material layers and connecting plates, wherein the connecting plates are used for fixing the middle plate and the restraining plates. The viscoelastic material layers are arranged between the two restraining plates. The middle plate is located between the viscoelastic material layers. The connecting plates are rotatably connected with the middle plate and the restraining plates. According to the damping device, the connecting plates are rotatably connected with the middle plate and the restraining plates, the damping device can be used for the node joint of any included angle, effectively consume energy, acting on structures, of wind vibration or earthquakes by controlling the angle displacement change between structural rods, and improve the rigidity of a transmission tower, and accordingly the function of restraining the structure vibration is achieved. In addition, the damping device has the advantages of being simple in structure, high in designability, convenient to machine and use, small in occupied space, low in cost and the like.
Description
technical field [0001] The invention relates to the field of anti-seismic devices of civil engineering structures, in particular to a damping device applicable to joints of joints with arbitrary angles and applied to installation nodes of structures such as beams and columns. Background technique [0002] Earthquake force and wind vibration force are the main control loads borne by the building structure, and are also the main factors leading to the damage and collapse of the building structure. Accurately understand the force mechanism and dynamic response of the structure under the action of dynamic load, and implement reliable measures for it. Anti-vibration protection measures are a frontier research topic. Structural energy dissipation and vibration reduction control is a new type of anti-vibration method, which uses energy dissipation and vibration reduction devices to consume external excitation energy to reduce the damage of external excitation to the main structure....
