After the welding and fixing are completed, it is connected to the connecting members 6 provided at both ends of the viscous damper through the limit pins 5 to complete the fixing, and the viscous damper after fixing needs to be horizontal;

[0053] After the installation is completed, during the actual use process, the controller provided inside the stepping motor 45 (the stepping motor 45 is powered by an external power supply) controls the drive shaft 48 to rotate according to the signal received by the signal receiving module. During the rotation of the drive shaft 48, it drives the cross plate 464 to rotate. During the rotation of the cross plate 464, it drives the adjusting plate 461 to move inside the through hole 422 through the intermediate member 462, thereby realizing the adjustment of the aperture size of the through hole 422, so as to adjust the damping strength of the viscous damper according to actual needs. Such a setting can realize damping adjustment according to the actual needs of the building during the actual use process, which is more stable;
