TECHNICAL FIELD

[0001] The present application relates to the technical field of dampers, in particular to a magneto-rheological elastomer type coupling beam damper. BACKGROUND

[0002] In the field of building seismic resistance, magneto-rheological elastomer type coupling beam dampers have received widespread attention in recent years. With the acceleration of urbanization, high-rise buildings are constantly emerging, and higher requirements are placed on the safety and stability of building structures under disasters such as earthquakes. Traditional passive dampers have certain limitations when facing complex and variable seismic conditions. Magneto-rheological elastomer type coupling beam dampers, due to their unique magneto-rheological effect, can quickly adjust the damping force according to the change of the magnetic field, providing a new solution for building structure damping, and gradually becoming a research and application hotspot.

[0003] Currently, magneto-rheological elastomer type coupling beam dampers are usually composed of magneto-rheological elastomer material, excitation coil, connecting components, etc. The working principle is based on the magneto-rheological effect. When the excitation coil is energized to generate a magnetic field, the magnetic particles in the magneto-rheological elastomer will align along the magnetic field direction, causing the stiffness and damping performance of the material to change, thereby generating damping force when the building structure vibrates, dissipating energy. In practical applications, by installing the damper at the coupling beam position, its damping characteristics are used to reduce the deformation and energy transfer of the coupling beam under the action of earthquakes.

[0004] However, the existing magneto-rheological elastomer type coupling beam dampers still have some problems. For example, in the seismic simulation test of a certain high-rise office building, when encountering strong earthquakes, the connecting part of the damper appears loose. This is because the existing connecting structure mostly uses simple bolt connection or welding method, which is easy to fatigue and damage under long-term vibration and impact, and cannot guarantee the stable work of the damper in the whole process of earthquake. Therefore, the present application provides a magneto-rheological elastomer type coupling beam damper to solve the problems existing in the prior art. SUMMARY

[0024] The combination mechanism includes an assembly plate 12, which plays an important role in connecting and fitting during the entire damper installation. The top of the assembly plate 12 is fixedly connected with a plurality of anchor rods 13, and the bottom of the assembly plate 12 is fixedly connected with a plurality of T-shaped columns 14. During installation, the top of the assembly plate 12 needs to be fitted to the building wall, at which time the anchor rod 13 is installed inside the building wall, and is usually directly poured to form an integral structure with the building, which can enhance the connection stability between the assembly plate 12 and the building structure. The outside of the T-shaped column 14 is sleeved with a stop ring I 15, which plays a key role in the subsequent assembly process. The assembly mechanism includes a rotating assembly and an assembly assembly. The rotating assembly includes a combination seat 8, which is rotatably connected to the inside of the combination hole 7. This rotatable connection allows the combination seat 8 to rotate flexibly inside the combination hole 7, facilitating angle adjustment to adapt to different installation requirements. The outside of the combination seat 8 is fitted to the outside of the connecting head 6, one end of the combination seat 8 is fixedly connected with a cover plate 9, the outside of the cover plate 9 is fitted to the outside of the connecting head 6, and the outside of the combination seat 8 is also fixedly connected with a support seat 10, the outside of the support seat 10 is also fitted to the outside of the connecting head 6. These fitted structures can ensure the tightness and stability of the rotating assembly during connection and cooperation. The assembly assembly includes a connecting plate 11, the bottom of which is fixedly connected with the outside of the support seat 10, which makes the connecting plate 11 form an integral whole with the rotating assembly. The top of the connecting plate 11 is fixedly connected with a plurality of fixed rods 16, and the inside of each fixed rod 16 is fixedly connected with an assembly rod 17. The outside of the assembly rod 17 is sleeved with a plurality of stop rings II 20, the outside of the assembly rod 17 is threadedly connected with a plurality of nuts 21, and the outside of the assembly rod 17 is slidably connected with a plurality of ear plates 19.

[0025] Specifically, when installing, first place the damper body 1 at a suitable position outside the building coupling beam, then use auxiliary parts such as bolts to pass through the mounting hole 3 to fix the base 2, complete the preliminary positioning of the damper body 1. Then attach the assembly plate 12 to the outside of the coupling beam, and fix the anchor rod 13 inside the building by pouring, so that the assembly plate 12 is firmly combined with the building structure. Then perform the butt joint work of the connecting plate 11 and the assembly plate 12, and make the bottom of the T-shaped column 14 fit the top of the connecting plate 11. At this time, the two arc-shaped clamping blocks 18 are respectively located on the outer side of the corresponding T-shaped column 14, and the construction personnel will move the two arc-shaped clamping blocks 18 to the T-shaped column 14, and then rotate the nut 21. Since the nut 21 is threadedly connected with the assembly rod 17, rotating the nut 21 will make the two ears 19 close to each other, and then make the two arc-shaped clamping blocks 18 clamp the T-shaped column 14. In this process, the stop ring one 15 can fill the gap between the arc-shaped clamping block 18 and the assembly plate 12, to ensure the tightness of the connection. Finally, place the U-shaped limiting plate 22 outside the assembly rod 17, and the outside of the U-shaped limiting plate 22 is in contact with the outside of the stop ring two 20. This cooperation can ensure the stable position of the nut 21, and even under the impact of earthquakes and the like, the nut 21 will not loosen. Through the close cooperation between the multiple arc-shaped clamping blocks 18 and the T-shaped column 14, the connection between the connecting plate 11 and the assembly plate 12 is more tightly. Compared with the traditional installation method using expansion bolts, this installation method is more reliable, and can ensure that the damper body 1 stably plays an effect when an earthquake occurs. When the building is subjected to the action of an earthquake, the coupling beam will vibrate and deform, driving the movable rod 4 to slide in the damper body 1. At this time, the wire 5 supplies power to the exciting coil to generate a magnetic field, changes the mechanical properties of the magnetorheological elastomer, makes the damper generate a large damping force, converts the mechanical energy input by the earthquake into heat energy and other forms of energy, thereby effectively reducing the vibration amplitude and energy transmission of the coupling beam, and protecting the safety of the building structure.

[0026] Working principle: first, the damper body 1 is placed in the building diaphragm outside, then use other auxiliary parts through the installation hole 3 fixed position of the base 2, assembly plate 12 is used to close to the diaphragm outside, anchor rod 13 is installed in the building, directly pouring into a whole, then use the connecting plate 11 and assembly plate 12 butt joint, so that the bottom of the T-shaped column 14 and the top of the connecting plate 11 close, two arc clamping block 18 is located in the corresponding T-shaped column 14 outside, then two arc clamping block 18 to T-shaped column 14 close, rotate the nut 21 so that the two ear plate 19 close to each other, so that two arc clamping block 18 can clamp T-shaped column 14, and the stop ring 15 can play the effect of filling the gap between arc clamping block 18 and assembly plate 12, finally, the U-shaped limiting plate 22 is placed outside the assembly rod 17, cooperate with the stop ring 20 can guarantee the position of the nut 21 stable, even if the impact also will not appear loose, and in the cooperation between the arc clamping block 18 and T-shaped column 14, make the connecting plate 11 and assembly plate 12 connection is more closely, compared with the traditional installation method with expansion bolt is more reliable, so can guarantee the damper body 1 in the earthquake, stable play effect, the mechanical energy input by the earthquake into the heat energy and other forms of energy dissipation, so as to reduce the vibration amplitude and energy transfer of diaphragm, protect the building structure.
