The skilled in the art can determine the specific meaning of the above words in the utility model in combination with the specific content of the technical scheme.
[0037] Referring to Figure 1 The utility model discloses a support of vibration and shock double control, including:
[0038] Pre -buried part 1 is buried in the installation foundation (such as concrete);
[0039] Vibration isolation structure 2, including at least one vibration isolation plate 21;
[0040] Shock isolation structure 3, including the shock isolation support body 31 of setting on the upper end of vibration isolation structure 2, the shock isolation support body 31 includes multiple layers of alternately superimposed metal layer and elastomer layer;
[0041] Connecting piece 4, through vibration isolation structure 2 and with pre -buried part 1 is connected.
[0042] In an embodiment, the vibration isolation plate 21 is provided with multiple, multiple vibration isolation plate 21 superimposed arrangement. Through the superposition vibration isolation plate 21, the performance is improved, and the original structure does not need to be greatly changed. The number of vibration isolation plate 21 can be adjusted according to the control frequency requirement of actual site, and the modular design makes it have high flexibility, and can be configured according to demand to achieve the required damping effect.
[0043] In an embodiment, referring to Figure 3 、 Figure 4 The vibration isolation plate 21 includes vibration isolation body 211 and the upper connecting flange 212 and the lower connecting flange 213 connected to the axial both ends of vibration isolation body 211, the upper connecting flange 212 and the lower connecting flange 213 extend radially outward on vibration isolation body 211, and the first through hole 214 suitable for the connecting piece 4 is uniformly distributed along the circumference of the upper connecting flange 212 and the lower connecting flange 213.
[0044] In an embodiment, referring to Figure 1As shown, the isolation structure 3 further comprises an upper connecting plate 32 and a lower connecting plate 33 connected to the axial ends of the isolation support body 31, the lower connecting plate 33 abuts against the upper connecting flange 212, and a second through hole 34 corresponding to the first through hole 214 and adapted for the connecting member 4 to pass through is arranged circumferentially along the lower connecting plate 33.
[0045] In one embodiment, the upper connecting flange 212, the lower connecting flange 213, the upper connecting plate 32, the lower connecting plate 33, the isolation body 211, the metal layer and the elastomer layer are all circular.
[0046] In one embodiment, the radial dimension of the isolation body 211 is greater than the radial dimensions of the metal layer and the elastomer layer; the radial dimension of the lower connecting plate 33 is equal to the radial dimension of the upper connecting flange.
[0047] In one embodiment, the isolation body 211 adopts a rubber plate. Specifically, a thick rubber plate, the peripheral end of which is radially concave, can provide a better compression deformation shape. It should be noted that, compared with a general rubber plate, "thick" means that the thickness of the rubber plate is larger, so it can provide greater deformation capacity and greater vibration reduction capacity.
[0048] In one embodiment, with reference to Figure 2 As shown, the connecting member 4 is a (high-strength) bolt, and the embedded part 1 comprises a connecting thread adapted to be connected with the bolt. This makes the overall installation process of the support simple and efficient, suitable for rapid construction on site, and significantly improves the construction efficiency.
[0049] The high-strength bolt is used to stack and fix the isolation plate 21 and the isolation support body 31, which not only limits the horizontal shear movement of the isolation plate 21, but also has a tensile function to prevent the support from overturning during use. The rubber plate is used for the isolation body 211, and the rubber is used for the elastomer layer, which can effectively consume vibration energy and more effectively control low-frequency vibration, while having excellent aging performance, simple maintenance and long service life.
[0050] In one embodiment, the metal layer adopts a steel plate; the elastomer layer adopts rubber. The multiple layers of steel plates and multiple layers of rubber are alternately stacked and bonded into one body through a vulcanization process.
[0051] It can be understood that the multiple layers of steel plates provide rigid support to ensure the strength of the structure, and the elastomer layer provides elastic buffering to absorb the energy of horizontal vibration, thereby reducing the horizontal impact on the building.
[0052] Working principle:
[0053] The vibration and shock double control support is pre-embedded in the concrete through the pre-embedded part 1, and is installed by penetrating the second through hole 34 of the lower connecting plate 33 from below through the second through hole 34 of the upper connecting flange 212 and the lower connecting flange 213, and then being screwed in the screw thread on the pre-embedded part 1.
[0054] When vertical vibration is generated by subway traffic or earthquake, the vibration energy can be transmitted to the vibration isolation plate 21. The vibration isolation plate 21 can only be compressed and deformed in the vertical direction due to the limitation of the bolt. The compression deformation can effectively consume the vibration energy, thereby reducing the transmission of the vertical vibration to the building and improving the comfort of the personnel in the building.
[0055] When horizontal vibration is generated by earthquake, the upper shock isolation support body 31 will be horizontally displaced and deformed. The shock isolation support body 31 is formed by alternately and cohesively vulcanizing multiple layers of steel plates and multiple layers of rubber, and can absorb and isolate the horizontal energy generated by the earthquake through the flexible structure, thereby reducing the influence of the horizontal vibration on the building and reducing the damage of the earthquake to the building.
[0056] Through the above arrangement, the vibration and shock double control support can not only effectively isolate the horizontal vibration, but also consume the vertical vibration, so as to finally realize the double control of the vibration and shock isolation of the building, and guarantee the structural safety of the building and the comfort of the internal environment.
[0057] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the utility model and not to limit. Although the utility model is described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and all should be covered in the scope of the claims of the utility model.
