Description

Technical Field

[0001] The utility model belongs to the technical field of building seismic isolation and vibration isolation, and specifically relates to a vibration dual-control support suitable for vibration and earthquake. Background Art

[0002] In order to ensure the safety of buildings or other structures, it is usually necessary to take vibration isolation or seismic isolation measures. Vibration isolation refers to reducing or eliminating the vibration generated by upper equipment or vehicles. By adding vibration-absorbing mechanical devices between the upper vibration-generating equipment or objects and the main structure, and installing vibration control bearings, the low-frequency and high-frequency vibrations transmitted to the main structure of the structure are absorbed and isolated, and the vibration energy is absorbed and dissipated to ensure the safety and durability of the main structure. Seismic isolation refers to adding a seismic isolation layer and installing sliding bearings between the upper structure and the foundation, which acts as a soft connection with the ground and offsets about 80% of the energy of the earthquake.

[0003] The current anti-seismic or anti-vibration structures of buildings or other structures either only have seismic isolation functions or only have vibration isolation functions. Buildings or other structures that only perform vibration control cannot effectively guarantee safety during earthquakes. Buildings or structures that must be seismically isolated due to high intensity or key defense cannot cope with structural damage caused by high-frequency and low-frequency vibrations. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, the utility model provides a dual-control vibration bearing suitable for vibration and earthquake, which has the dual functions of shock absorption and vibration reduction, and can improve the safety of structures such as buildings, railway bridges, tunnel entrances, subways, and substations in high-intensity areas during daily use and when earthquakes occur. At the same time, it has the characteristics of small size and weight, simple installation, low installation accuracy requirements, and convenient maintenance.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] The dual-control vibration support suitable for vibration and earthquake includes an upper support, an upper slider and a lower slider; the upper support is arranged above the upper slider, and an elastic component is arranged between the upper support and the upper slider; the lower bottom surface of the upper slider is provided with an arc-shaped convex surface; the upper surface of the lower slider is provided with an arc-shaped concave surface; the upper slider is arranged above the lower slider, the arc-shaped convex surface of the upper slider is in contact with the arc-shaped concave surface of the lower slider, and the two can slide in contact through the arc-shaped convex surface and the arc-shaped concave surface.

[0007] Preferably, the elastic component comprises a coil spring and a rubber support; the rubber support is arranged between the upper support and the upper slider, and the coil spring is arranged around the outer circumference of the rubber support.

[0008] Preferably, an upper support clamping ring is provided on the lower bottom surface of the upper support; an upper slider clamping ring is provided on the upper surface of the upper slider which is sleeved with the support plate clamping ring; and a rubber ring is provided between the upper support clamping ring and the upper slider clamping ring.

[0009] Preferably, an anchoring hole plate is arranged on the outer periphery of the upper support; the lower end surface of the upper support is also provided with an upper support helical spring slot and an upper support rubber support slot for fixing the helical spring and the rubber support.

[0010] Preferably, the upper surface of the upper slider is provided with an upper slider coil spring retaining groove and an upper slider rubber support retaining groove which are opposite to the upper support and are used to fix the coil spring and the rubber support respectively.

[0011] Preferably, an anchor hole plate is provided on the outer periphery of the lower sliding block.

[0012] Preferably, an anti-slip ring is provided on the outer periphery of the arc-shaped concave surface of the lower slider.

[0014] Beneficial effects of the utility model:

[0015] The vibration dual-control bearing of the utility model can not only absorb and dissipate the high-frequency and low-frequency vibrations generated by the vibrating object above, but also realize soft connection during earthquakes, reduce the seismic response of the upper structure, and realize dual control of vibration and shock.

[0027] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0028] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention will be understood according to specific circumstances.

[0029] like Figure 1-7 As shown, the vibration and earthquake dual-control bearing suitable for vibration and earthquake includes an upper bearing 1, an upper slider 2 and a lower slider 3, which are arranged in sequence from top to bottom. Anchor hole plates 8 are respectively arranged on the outer periphery of the upper bearing 1 and the lower slider 3. The upper bearing 1 is connected and fixed to the upper main part of the building (such as the upper pier) through anchor rods, and the lower slider 3 is connected and fixed to the lower main part of the building (i.e., the lower pier) through anchor bolts. An elastic component is provided between the upper bearing 1 and the upper slider 2 to play a vibration isolation role; the upper slider 2 and the lower slider 3 are connected in sliding contact to play a seismic isolation role.

[0030] The elastic component includes a coil spring 4 and a rubber support 6. The rubber support 6 is arranged in the middle of the upper support 1 and the upper slider 2. The coil spring 4 is arranged around the outer periphery of the rubber support 6. When vibration occurs, the elastic component arranged between the upper support 1 and the upper slider 2 can play a vibration isolation role, absorb and dissipate the vibration energy, and ensure the safety and durability of the main body. The coil spring 4 and the rubber support 6 respectively isolate vibrations in different frequency ranges, thereby achieving effective isolation of low-frequency vibrations and high-frequency vibrations.

[0031] The upper support 1 is a plate-like structure, and an upper support collar 11 is provided on its lower bottom surface; an upper slider collar 21 matching the upper support collar 11 is provided on the upper surface of the upper slider 2; the upper support 1 and the upper slider 2 are sleeved together through the upper support collar 11 and the upper slider collar 21. The sleeve connection between the upper support collar 11 and the upper slider collar 21 enables the upper support 1 and the upper slider 2 to form a whole that cannot move relative to each other in the horizontal direction, but can move freely in the vertical direction. Combined with the setting of the elastic component, vibration isolation is achieved. A rubber ring 7 is provided on the sleeve surface of the upper support collar 11 and the upper slider collar 21 to prevent the upper support collar 11 and the upper slider collar 21 from directly contacting and transmitting vibration.

[0032] The upper support 1 and the upper slider 2 have upper support coil spring slots 12 and upper slider coil spring slots 22, upper support rubber support slots 13 and upper slider rubber support slots 23, respectively, on the opposing surfaces thereof. The upper and lower ends of the coil spring 4 are respectively fixed in the upper support coil spring slots 12 and the upper slider coil spring slots 22, and the upper and lower ends of the rubber support 6 are respectively fixed in the upper support rubber support slots 13 and the upper slider rubber support slots 23.

[0033] The middle part of the lower end surface of the upper slider 2 is provided with an arc-shaped convex surface 24, and the upper surface of the lower slider 3 is provided with an arc-shaped concave surface 34. The curvatures of the arc-shaped convex surface 24 and the arc-shaped concave surface 34 are the same. The arc-shaped convex surface 24 of the upper slider 2 and the arc-shaped concave surface 34 of the lower slider 3 are in contact. The upper slider 2 is arranged above the lower slider 3, and the two can slide in contact through the arc-shaped convex surface 24 and the arc-shaped concave surface 34. During an earthquake, the upper slider 2 and the lower slider 3 slide against each other, and while not affecting the vibration isolation function of the upper support 1 and the upper slider 2, the horizontal movement of the upper slider 2 and the lower slider 3 absorbs and dissipates the seismic energy, achieving a seismic isolation effect, and preventing damage or collapse of the building during an earthquake.

[0034] An anti-slip ring 35 is provided on the outer periphery of the arc-shaped concave surface 34 of the lower slider 3 to prevent the upper slider 2 from slipping out of the lower slider 3 .

[0035] As a preferred solution, the surfaces of the arcuate convex surface 24 and the arcuate concave surface 34 are coated with a wear-resistant material, such as polytetrafluoroethylene and other wear-resistant and sliding materials.

[0036] The utility model can improve the safety and economy of buildings, railway bridges, tunnel entrances and other structures in daily use and when an earthquake occurs. It is convenient to install and repair, small in size and weight, low in installation precision, high in fault tolerance, and avoids the situation that the upper and lower pier anchor bolts are not accurately aligned, which leads to the inability to install. At the same time, modular installation avoids the situation that the installation fails due to the confusion of individual parts on site.

[0037] The utility model can achieve vibration isolation and seismic isolation at the same time. First, it can avoid structural damage and reduced durability of seismic isolation buildings due to the inability to effectively control vibration, and even affect the comfort of use and building safety, such as buildings for special medical equipment, factories for high-precision machine tools, railway bridges and culverts, subways, etc. Second, it can avoid earthquake damage or collapse caused by the inability to isolate buildings with vibration control equipment, such as railway bridges, culverts, substations in high-intensity areas, power transmission and distribution equipment, etc. The utility model controls vibration and shock at the same time, ensuring the safety of daily use and safety during earthquakes and safety during earthquakes of buildings and structures of the above types or functions, ensuring that the functions of use in the epicenter and after the earthquake are not affected, and greatly improving the protection capacity of such infrastructure.

[0038] When in use, the upper support 1 and the upper slider 2 and the internal rubber support 6 and the coil spring 4 can be processed as a whole in the factory to form a vibration control unit, and the lower slider 3 can be processed separately; as two main components, they are transported to the site for on-site assembly. During installation, the lower slider 3 is installed on the top of the lower pier through anchor bolts, and the vibration control unit is placed on the lower slider 3 so that the sliding surfaces of the two are in contact. Due to the effect of gravity, they can be automatically aligned at the bottom of the arc, and finally the upper support 1 is fixed to the bottom of the upper pier with bolts. The installation is now complete.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
