Background
Spring isolators are one of the most commonly used types of steel isolators, and are commonly in the form of spirals, discs, rings, plates, and the like. The high-frequency vibration isolator has the advantages of large static compression amount, low natural frequency and good low-frequency vibration isolation performance; the corrosion of oil, water and the like is resisted, and the performance is not affected by temperature change; the damping steel spring vibration isolator is not easy to age, does not creep and the like, so the damping steel spring vibration isolator is widely used for general equipment, power industry, metal processing field, precision machining, precision measuring equipment and the like.
The damping steel spring vibration isolator is partially applied to the field of vibration reduction and vibration isolation of buildings at present, but is not widely popularized, and related building vibration isolation national standards such as product design, construction process, acceptance detection and the like are not related at present, so that vibration isolator products provided by various suppliers have no unified standard, and the difference of functionality and product design rationality is larger. The traditional damping steel spring vibration isolator structure for building vibration reduction is generally an upper embedded steel plate, an anti-slip cushion layer, a leveling steel plate, a steel spring vibration isolator and a lower embedded steel plate, because the upper part adopts the anti-slip cushion structure, the vibration isolator can not be directly welded with the upper embedded steel plate, and the upper building structure still has the horizontal sliding phenomenon when the vibration is larger; meanwhile, the locking bolt structure of the vibration isolator can cause a vibration 'sound bridge' phenomenon, so that up-and-down vibration is conducted; in addition, due to the limited space of the building column foundation, vertical stiffness arrangements are often preferred during isolator design, sacrificing the damping performance (damping space) of the isolator.
Accordingly, new techniques and equipment are needed to at least partially address the problems existing in the prior art.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Fig. 1 is a schematic cross-sectional structure of a vibration isolator for vibration damping of a building according to an embodiment of the present utility model; fig. 2 is a schematic plan view of a construction vibration isolator according to an embodiment of the present utility model. Referring to the drawings, the building vibration isolator of the embodiment may include an upper deck plate 10, a plurality of spring assemblies 20, a connection assembly 30, a lower deck plate 40, a damping material 50, an upper force-receiving plate 60-and a lower force-receiving plate 70. Wherein the plurality of spring assemblies 20 are disposed between the upper and lower cover plates, and the connection assembly 30 passes through the upper cover plate 10, the spring assemblies 20, and the lower cover plate 40 and fixes the upper cover plate 10, the spring assemblies 20, and the lower cover plate 40 together. Damping material 50 is disposed in the space between the upper and lower cover plates to form a common cylinder structure with spring assembly 20. The upper stress plate 60 is fixed on the upper cover plate 10, and the lower stress plate 70 is fixed below the lower cover plate 40, and can be directly fixed on the upper and lower embedded steel plates.
As shown, the spring assembly 20 may include a spring member 21, an upper spring retainer 22, a lower spring retainer 23, and a flexible spring backing plate 24, the upper spring retainer 22 being fixed to the lower surface of the upper cover plate 10, the lower spring retainer 23 being fixed to the upper surface of the lower cover plate 40, and both ends of the spring member 21 being respectively sleeved on the upper spring retainer 22 and the lower spring retainer 23, thereby restricting displacement of the spring member in the horizontal direction. A flexible backing plate 24 may be provided at one or both of the upper and lower ends of the spring element 21, thereby enabling the spring element 21 to be in contact with the surface of the upper/lower cover plates 10/40 through the flexible backing plate 24, effectively suppressing high frequency failure. The flexible backing plate 24 may be made of polyurethane, rubber, or the like, for example. Screw holes are formed in the upper cover plate 10/lower cover plate 40 for connection fixation of the bolts 31. The sprung back-up ring 22 and the unsprung back-up ring 23 are disposed about the periphery of the threaded bore (if the threaded bore is formed in the upper and lower cover plates for the spring assembly 20). In addition, the number of the spring assemblies 20 may be set according to actual needs, and is not limited to 9 as shown in the drawings.
As shown, the connection assembly 30 may include bolts 31, bolt cushions 32, and bolt sleeves 33 for securing the upper cover plate 10, the spring assembly 20, and the lower cover plate 40 together. Thus, the number of connection assemblies 30 may be set as desired, 4 being shown, located at the four corners of the isolator, thereby passing through four of the plurality of spring assemblies 20. More specifically, the bolts 31 pass through screw holes formed in the upper and lower cover plates 10 and 40, and the bolt cushion 32 is provided in the screw holes to prevent direct contact between the bolts 31 and the upper and lower cover plates 10 and 40, whereby vibration conduction at the bolt portions can be effectively prevented. The bolt cushion 32 may be made of polyurethane or rubber, for example. The bolt sleeve 33 is fixed, for example welded, to the lower cover plate 40, and has a dimensional inner diameter that does not interfere with the bolt mounting, so that the bolt 31 can pass therethrough. The damping material 50 is not provided in the inner space of the bolt sleeve 33 to prevent the damping material from leaking from the screw hole of the lower cover plate. The inner diameter of the bolt sleeve 33 may be smaller than the inner diameter of the under-spring retainer 23, whereby the under-spring retainer 23 may be disposed at the outer periphery of the bolt sleeve 33; or the bolt sleeve 33 may replace the under-spring retainer 23, thereby eliminating the under-spring retainer 23.
The construction vibration isolator further includes an upper baffle 11 disposed around the lower surface of the upper deck 10 and extending downward, a lower baffle 41 disposed around the upper surface of the lower deck 40 and extending upward, and a sealing member 25 sealing a gap between the upper baffle 11 and the lower baffle 41. Thus, the upper cover plate 10, the upper barrier 11, the lower cover plate 40, the lower barrier 41, and the sealing member 25 constitute a closed space in which the damping material 50 is disposed, and the damping material 50 is not particularly limited, and may be, for example, a solid damping material or a liquid damping material which is conventional in the art. More specifically, the heights of the lower baffle 41 and the bolt sleeve 33 are set to be greater than the height of the damping material filling while the upper height is reserved to avoid contact with the upper structure when the vibration isolator is compressed. This can avoid leakage of the damping material. The sealing member 25 can be connected, sealed and fixed with the upper baffle 11 and the lower baffle 41 respectively in the form of hoops and the like.
Referring to the drawings, the upper force-receiving plate 60 may include an upper top plate 61 and an upper rib plate 62, and the upper top plate 61 is fixed, e.g., welded, to the upper cover plate 10 by the upper rib plate 62. The upper top plate 61 may be directly fixedly connected with an upper pre-buried steel plate of the building. In addition, the upper rib plate 62 is provided with a lifting hole 621, so that the product can be conveniently transported, installed, maintained and repaired. The lower force receiving plate 70 includes a lower top plate 71 and a lower rib 72, and the lower top plate 71 is fixed, for example welded, under the lower cover plate 40 by the lower rib 72. The lower top plate 71 may be directly fixedly connected with a lower pre-buried steel plate of the building.
The components of the vibration isolator of the embodiments may be made of suitable materials, such as steel materials, unless specifically indicated.
Compared with the traditional damping steel spring vibration isolator, the utility model has the following advantages:
1) The upper anti-slip cushion layer is canceled, and the vibration isolator is welded and connected with the embedded steel plates up and down, so that the connection performance between the vibration isolator and the building structure is improved, and the horizontal sliding phenomenon of the building is effectively avoided or relieved.
2) The arrangement of the flexible backing plate can effectively inhibit high-frequency failure;
3) The locking bolt is additionally provided with a bolt port cushion, so that vibration conduction at the bolt position is effectively avoided;
4) The damping material adopts a common cylinder type damping structure, so that the setting space of an independent damper is saved while the damping performance is ensured, the column head expansion of the building column space can be reduced, and the stress of the building structure is good.
The utility model not only has the structural optimization, but also reserves the jacking maintenance installation space of the vibration isolator, and is provided with the lifting hole of the vibration isolator and the spring seal anti-corrosion protection of the vibration isolator, thereby being convenient for the transportation, the installation, the maintenance and the repair of products.
The foregoing is merely a preferred embodiment of the present patent, and it should be noted that modifications could be made by those skilled in the art without departing from the scope of the present patent, and such modifications should also be considered as being within the scope of the present patent.
