Further, the upper rubber pad 3 fixed to the upper stopper 1 is brought into contact with the first end of the magnetic alloy steel column 4 as a contact portion, and generates a required frictional force when the relative sliding occurs between the two.

On the basis, the lower stop block 5 is further provided with a placement hole 5-2 at the bottom of the insertion groove 5-1 for being matched with the connecting bolt 7, so that the lower stop block 5 is fixedly connected with the lower support 22.
When the lower stop block 5 with the structure is fixedly arranged on the lower support 22, the second end of the magnetic alloy steel column 4 is accommodated in the inserting groove 5-1, so that the second end of the magnetic alloy steel column 4 is always limited in the inserting groove 5-1 of the lower stop block 5. Therefore, the displacement of the high-strength magnetic alloy steel column 5 can be limited by the lower stop block 5 in the initial state, and the magnetic alloy steel column 4 can be guided to smoothly fall into the safety slot 5-1 of the lower stop block when the high-strength magnetic alloy steel column falls down (such as caused by an earthquake).
On the basis of the lower stopper 5, the present example further provides a strong magnet 2, i.e., a second strong magnet 2, in the mounting slot 5-1 of the lower stopper 5.

The second strong magnet 2 arranged in this way can be matched with the lower stop block 5, and the high-strength magnetic alloy steel column 4 is sucked after falling down, so that the high-strength magnetic alloy steel column is prevented from being sucked up again by the strong magnet in the upper stop block.
Further, in this example, a layer of lower rubber pad 6 is further disposed in the installation slot 5-1 of the lower stopper 5, and the lower rubber pad 6 can cover the whole second strong magnet 2, so as to protect the second strong magnet 2 in the installation slot 5-1, and can protect the strong magnet below the second strong magnet from being broken by the falling high-strength magnetic alloy steel column 4.
Referring to fig. 3e, there is shown an example of the constitution of the lower rubber pad 6 in this example. As can be seen from the figure, the whole lower rubber pad 6 is a square rubber block structure adapted to the mounting slot 5-1 of the lower stopper 5, and other size structures can be determined according to practical requirements, and are not limited herein.
From this, cooperate based on above-mentioned structure between lower dog 5, second strong magnet 2 and the lower rubber pad 6 and form corresponding magnetism and inhale the subassembly, the subassembly is inhaled to the magnetism that forms and is inhaled the friction subassembly, through corresponding connecting bolt 7 fixed the setting on the lower support 22 of shock insulation support 20.

The magnetic alloy steel column 4 in this example is distributed between the magnetic attraction friction components and the magnetic attraction components which are distributed relatively, and can generate magnetic attraction force with the magnetic attraction friction components and the magnetic attraction components respectively, and the magnetic attraction friction components and the magnetic attraction components are matched dynamically to form corresponding friction force to provide additional lateral rigidity for the shock insulation support.
Referring to fig. 3f, there is shown an exemplary view of the construction of the magnetic alloy steel column 4 in this example. As can be seen from the figure, the whole magnetic alloy steel column 4 is a column structure made of magnetic alloy steel material, one end of the column is matched with the upper rubber pad 3 in the magnetic friction assembly, and the other end is matched with the inserting groove 5-1 on the lower stop block 5 in the magnetic friction assembly.
The specific material composition of the magnetic alloy steel column 4 is not limited, and may be other magnetic materials instead of the magnetic alloy steel material according to actual needs. Meanwhile, the size structure of the magnetic alloy steel column 4 ensures that when the first end of the magnetic alloy steel column 4 is adsorbed by the magnetic attraction friction assembly, the second end of the magnetic alloy steel column 4 is kept suspended and inserted in the magnetic attraction assembly.
The magnetic friction type wind-resistant device 10 formed based on the scheme can be singly used or matched with a plurality of groups to be used when being applied specifically, and is respectively fixed on a shock-insulation support or a single wind-resistant support through corresponding connecting screws.
Referring to fig. 1 and 2, an example of an application of the magnetic friction type wind-resistant device 10 integrated on the shock-insulating support 20 is shown in this example.
Taking the illustrated scheme as an example, in the application example, 4 groups of magnetic friction type wind-resistant devices 10 are arranged on the shock insulation support 20, and the four groups of magnetic friction type wind-resistant devices 10 are respectively distributed at corners of the shock insulation support 20.
The magnetic attraction friction components and the magnetic attraction components in each group of magnetic attraction friction type wind resistance device 10 are oppositely and respectively fixedly arranged on the upper support and the lower support of the shock insulation support 20 through corresponding connecting bolts, and meanwhile, the magnetic alloy steel columns are distributed between the magnetic attraction friction components and the magnetic attraction components in a matched mode, and specific distribution structures are not repeated here as described above.
Here, the number of applications of the magnetic friction type wind-resistant device 10 may be increased or decreased according to the wind-resistant performance in actual use.
Meanwhile, the structural forms of the upper stop block 1, the lower stop block 5 and the high-strength magnetic alloy steel column 4 in each group of magnetic friction type wind resistance devices 10 are not limited to the illustrated rectangular column form, and other shapes such as a cylinder shape can be adopted according to requirements.
For the shock insulation support 20 integrated with the magnetic friction type wind resistance device 10, each group of magnetic friction type wind resistance device 10 provides additional lateral rigidity for the shock insulation support 20 in a wind resistance state through friction force between the upper rubber pad 3 and the high-strength magnetic alloy steel column 4.
The friction force can be expressed by the formula F u ＝μ(G+F B ) Wherein mu is the friction coefficient between the upper rubber pad 3 and the high-strength magnetic alloy steel column 4, G is the gravity of the high-strength magnetic alloy steel column 4, F B Is the attractive force of the strong magnet 2 in the lower stop block 5 which is suffered by the high-strength magnetic alloy steel column 4. Therefore, in the practical application process, the horizontal anti-side rigidity of the wind resistance device can be adjusted by adjusting the three parameters.
The mechanism and process of realizing wind resistance and earthquake resistance of the shock insulation support 20 integrated with the magnetic friction type wind resistance device 10 are described in detail below with reference to the drawings.
Referring to fig. 4a, the shock insulation support integrated with the magnetic friction type wind-resistant device is in a non-shock-resistant initial state and in a wind-resistant state.
In combination with the illustration of fig. 1, in the initial state, the shock insulation support integrated with the magnetic friction type wind resistance device is kept motionless, the strong magnet 2 in the upper stop block 1 of the wind resistance device attracts the high-strength magnetic alloy steel column 4 to be suspended, the upper rubber pad 3 is arranged between the two, and the bottom of the high-strength magnetic alloy steel column 4 is limited in the groove of the lower stop block 5. Under the action of wind load, the friction force between the high-strength magnetic alloy steel column 4 and the upper rubber pad 3 can prevent the vibration isolation support from horizontally deforming, so that the vibration isolation support and the wind resistance device still keep motionless, and the vibration isolation support is in a wind resistance state at the moment.
Referring to fig. 4b, the vibration isolation support integrated with the magnetic friction type wind-resistant device is in an anti-vibration initial state, wherein the vibration isolation support starts to deform, and the integrated wind-resistant device generates certain sliding deformation.
Referring further to fig. 4c, the shock insulation support integrated with the magnetic friction type wind-resistant device is shown in a shock-resistant reinforced state, wherein the shock insulation support is deformed and increased, and the integrated wind-resistant device is slid and deformed and is about to be separated.
Referring further to fig. 4d, the shock-insulating support integrated with the magnetic friction type wind-resistant device is shown in a shock-resistant maximum state, wherein the shock-insulating support is significantly deformed, and the integrated wind-resistant device is in a separated state.
It can be seen that when the shock insulation support integrated with the magnetic friction type wind resistance device is in a shock-resistant state, under the action of an earthquake, the horizontal force born by the shock insulation support exceeds the friction force between the high-strength magnetic alloy steel column 4 and the upper rubber pad 3, and sliding deformation is generated between the high-strength magnetic alloy steel column 4 and the upper rubber pad 3;
when the deformation reaches a certain degree, the high-strength magnetic alloy steel column 4 is not enough to maintain the suspension, so that the high-strength magnetic alloy steel column falls into the groove of the lower stop block 5, and the deformation capacity of the shock insulation support is fully released.
Referring to fig. 4e, the shock insulation support integrated with the magnetic friction type wind-resistant device is shown to recover after the earthquake is finished. At this time, the vibration isolation support is reset, and the integrated wind-resistant device is in a longitudinally separated state.
After an earthquake, the vibration isolation support is reset, the high-strength magnetic alloy steel column 4 can be pulled out of the groove of the lower stop block 5 and is adsorbed on the strong magnet 2 of the upper stop block 1 again, so that the support performance can be reset, and the wind resistance support can be restored again.
As can be seen from the above examples, the reusable magnetic friction type wind-resistant device provided in this example can convert rigidity under wind and earthquake, can be kept motionless under wind load to provide additional lateral rigidity to limit deformation of the shock-resistant support, and can be automatically separated under earthquake to fully release the deformation capability of the shock-resistant support.
Secondly, the reusable magnetic friction type wind-resistant device provided by the embodiment does not need to replace an original part after an earthquake, and can be recovered into a wind-resistant support for reuse only by pulling out the high-strength magnetic alloy steel column 4 from the groove of the lower stop block 5 and re-adsorbing the high-strength magnetic alloy steel column at the position of the strong magnet 2 of the upper stop block 1.
Meanwhile, the reusable magnetic friction type wind-resistant device provided by the embodiment is easy to install and detach, and the number of the wind-resistant devices, the size and the shape of the high-strength alloy steel column 4 and the like can be adjusted according to the wind load so as to meet the requirements, and the wind-resistant vibration isolation requirements of different areas are met.
Finally, the reusable magnetic friction type wind-resistant device provided by the embodiment is flexible in overall use, and can be installed on a conventional shock-insulation support and also can be used as an independent wind-resistant support.
The reusable magnetic friction type wind-resistant device provided by the example can be used for a shock-proof building with wind resistance requirements.
