Only the specific structures and working processes of one set of the adjusting assembly 101 and the main body assembly 201 will be described in detail below.

[0026] Please refer to Appendix Figure 1 to Appendix Figure 3 As shown, the adjusting assembly 101 includes a moving mechanism, a lifting mechanism, and a locking mechanism. A groove 10 is formed in the housing 30. The moving mechanism is movably installed in the groove 10. The lifting mechanism is arranged on the moving mechanism and locked to the housing 30 through the locking mechanism. The tuned mass damper body 21 is arranged on the moving mechanism through the main body assembly 201, so that the tuned mass damper body 21 can be horizontally adjusted and arranged on the housing 30 through the moving mechanism, and can be lifted and adjusted on the housing 30 through the lifting mechanism, thereby fixing the tuned mass damper body 21 to the shock absorption point of the building structure.

[0027] The moving mechanism can slide in the groove 10, thereby driving the lifting mechanism, the locking mechanism, and the tuned mass damper body 21 to slide synchronously, and further realizing the horizontal position adjustment of the tuned mass damper body 21.

[0028] The lifting mechanism can lift in the groove 10, thereby driving the synchronous lifting of the locking mechanism and the tuned mass damper body 21, and further realizing the height position adjustment of the tuned mass damper body 21.

[0030] Please refer to Appendix Figure 3 As shown, the moving mechanism includes a slider 12. A sliding groove 11 is formed at the bottom of the groove 10. The sliding groove 11 is arranged along the length direction of the groove 10. The slider 12 is slidably installed in the sliding groove 11. The lifting mechanism is installed on the slider 12, so that the lifting mechanism can be movably arranged in the groove 10.

[0031] Preferably, the slider 12 and the chute 11 can adopt a matching T-shaped structure, which can ensure the smooth sliding of the slider 12 along the chute 11 while preventing the slider 12 from disengaging from the chute 11. When the slider 12 slides along the chute 11, it drives the lifting mechanism and the tuned mass damper body 21 to slide synchronously, thereby adjusting the installation position of the tuned mass damper body 21.

[0032] Please refer to the appendix Figure 3 , the lifting mechanism includes a first plate body 13, a cylinder 14 and a second plate body 15; the bottom of the first plate body 13 is fixedly connected to the slider 12, and the second plate body 15 is liftably arranged on the first plate body 13 through a plurality of cylinders 14; the locking mechanism is connected between the second plate body 15 and the housing 30, and the main body assembly 201 includes a mounting base 20, and the tuned mass damper body 21 is mounted on the second plate body 15 through the mounting base 20, so that the tuned mass damper body 21 is movably and liftably arranged on the housing 30.

[0033] Preferably, both the first plate body 13 and the second plate body 15 are made of flat steel plates. The width of the first plate body 13 is slightly smaller than the width of the groove 10, so that the first plate body 13 slides in the groove 10 along with the slider 12. The width of the second plate body 15 is the same as the width of the housing 30, so that the second plate body 15 is arranged above the housing 30 through the cylinders 14, which is convenient for installing the tuned mass damper body 21 and the locking mechanism.

[0034] Preferably, the height of the cylinder 14 is slightly smaller than the depth of the groove 10, so that when the piston rod of the cylinder 14 is at the minimum stroke, the second plate body 15 fits on the housing 30. The height of the second plate body 15 is adjusted by using the stroke of the piston rod of the cylinder 14, and then the height of the tuned mass damper body 21 is adjusted. Four cylinders 14 can be arranged, which are respectively located at the four corners of the first plate body 13.

[0035] Please refer to the appendix Figure 1 to the appendix Figure 4 , the locking mechanism includes a fixing bolt 16 and a third plate body 17; the second plate body 15 is located above the housing 30, and third plate bodies 17 are vertically connected to both ends of the second plate body 15 respectively, and the two third plate bodies 17 are respectively slidably attached to both side surfaces of the housing 30; the fixing bolt 16 passes through and is screwed to the second plate body 15 and abuts against the top surface of the housing 30.

When the fixing bolts 16 are screwed in by threads, the fixing bolts 16 can be tightened against the top surface of the housing 30. The fixing bolts 16 provide a force in the direction away from the housing 30 for the second plate body 15, and the cylinder 14 provides a force in the direction close to the housing 30 for the second plate body 15, so as to ensure the force balance of the second plate body 15, and further ensure the installation stability of the tuned mass damper body 21.

[0037] Preferably, four fixing bolts 16 can be symmetrically arranged on both sides of the groove 10 to further improve the installation stability of the tuned mass damper body 21.

[0038] Two third plate bodies 17 can be perpendicularly welded to the second plate body 15. The two third plate bodies 17 are attached to both side surfaces of the housing 30, which can play a role in lateral limit and ensure the sliding adjustment stability of the second plate body 15 and the tuned mass damper body 21 installed thereon. After the second plate body 15 slides in place, the third plate bodies 17 can be welded and fixed to the housing 30 to improve the locking effect of the locking mechanism, thereby ensuring the locking reliability of the second plate body 15 and the tuned mass damper body 21 installed thereon.

[0042] Preferably, the lifting ring 22 can be made of a steel plate and welded to both end faces of the housing 30, which is convenient for connecting the housing 30 with components such as the floor slab in the building structure.

[0043] Please refer to the attached Figure 1 to the attached Figure 4 , a notch 24 is formed at the bottom of the support plate 23, so that the support plate 23 is clamped on the steel bars inside the building structure through the notch 24.

[0044] Preferably, the notch 24 can adopt a semicircular structure, and the diameter of the notch 24 can be determined according to the diameter of the steel bars in the installation components such as the floor slab, so that the notch 24 can be clamped and tied to the steel bars, thereby making the shell 30 buried in the components of the building structure stably and reliably.
