Detailed Description

The following describes in detail the embodiments of the vibration dual control device and the building supporting structure provided by the utility model with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a vibration dual control device according to an embodiment of the present utility model, including a vertical vibration isolator 12 and a slidable spherical hinge support 13. The above structure is used to carry the building 14 above.

In this embodiment, the vertical vibration isolator 12 is a spring isolation vibration support, and specifically includes a bottom plate 121 and a top plate 122, a plurality of springs 123 are disposed between the bottom plate 121 and the top plate 122, a damper (not shown) or a vertical compression limiting block (not shown) or a combination of both may be further disposed in the springs 123, and a layer of cladding material (not shown) may be further integrally disposed outside the plurality of springs 123. Vertical vibration of building 14 can be isolated and absorbed by a plurality of springs 123 between floor 121 and roof 122. The above structure obviously cannot isolate lateral displacement from the upper building 14. The lateral seismic action causes lateral displacement of the building 14, thereby driving lateral displacement of the roof 122, which can cause failure of the spring isolation vibration mount if the lateral displacement exceeds the horizontal deformability of the springs.

In order to solve the problem that the spring isolation vibration mount can only isolate vertical vibration, the embodiment further provides a slidable spherical hinge mount 13 between the upper part of the vertical vibration isolator 12 and the building 14. The number of said slidable spherical hinge supports 13 may be one or more. The slidable spherical hinge support 13 comprises a spherical base 131 and a sliding panel 132 arranged on the spherical base 131, wherein a spherical crown slider 133 matched with the spherical base in shape is arranged below the sliding panel 132. The lower plate of the spherical base 131 and the spherical surface may be of an integral or separate structure. The sliding panel 132 is a steel base plate, and a surface-clad stainless steel plate.

The spherical cap sliding block 133 is made of steel, and polytetrafluoroethylene is attached to the surface of the spherical cap sliding block. The contact surfaces of the spherical crown slider 133, the spherical base and the sliding panel member are made of antifriction materials such as polytetrafluoroethylene, so as to reduce friction during vibration and rotation.

The slidable spherical hinge support 13 can release the lateral displacement with the upper supported building 14 by sliding between the spherical crown slider 133 and the sliding panel 132, and due to the construction of the spherical crown slider 133 and the spherical base 131, the pressure of the upper building 14 on the spherical base 131 is maintained vertically downward by the relative rotation between the spherical crown slider 133 and the spherical base 131 regardless of the relative displacement and the relative rotation angle between the sliding panel 132 and the spherical base 131, thereby causing the vertical vibration isolator 12 to be in a substantially central stress state, protecting the vertical vibration isolator 12 below. Therefore, the present embodiment achieves horizontal seismic isolation and vertical vibration isolation of a building while having sufficient bearing capacity by the combination of the vertical vibration isolator 12 and the slidable spherical hinge support 13.

In one embodiment, a plurality of vibration dual control devices as described above may be employed to form a building support structure.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
