Description

Assembleable lightweight high-performance anti-vibration base and usage instructions Technical Field

[0001] This invention relates to the field of micro-vibration control technology, and in particular to an assemblable, lightweight, high-performance anti-micro-vibration base and its usage method. Background Technology

[0002] With societal progress and development, industrial manufacturing and basic research are increasingly moving towards higher and ultra-high precision, while simultaneously demanding ever-increasing precision in their applications. Precision equipment is a crucial component of high-tech development and a significant standard for measuring a nation's high-tech level. Precision instruments are indispensable in precision machining, engineering measurement, and experimental setups; without them, nothing else is possible.

[0003] Precision instruments have extremely high requirements for their operating environment, such as indoor temperature, cleanliness, static electricity, dust, and environmental vibration levels. Failure to meet any of these external factors can cause difficulties in the operation of the precision instruments. Environmental vibration has a particularly significant impact on precision instruments; harsh dynamic environments can adversely affect them, and prolonged exposure to such environments can shorten their lifespan. Therefore, to protect the production and use of precision equipment, vibration reduction and isolation measures are necessary. Utilizing vibration control technology to reduce and isolate vibrations, and installing appropriate vibration isolators between the equipment and its foundation, can ensure that precision equipment meets normal operating conditions.

[0004] Traditional anti-vibration platforms typically utilize large volumes of concrete, resulting in a bulky and cumbersome design that relies on sheer force to resist minor vibrations. This limits their applicability, currently only suitable for new buildings. For existing buildings and high-precision equipment, using traditional anti-vibration platforms would introduce a sudden surge in load, potentially causing the structure's load-bearing capacity to fail, threatening structural safety and requiring reinforcement, thus increasing the overall cost of micro-vibration control. Furthermore, the large size of some precision instruments necessitates a correspondingly larger anti-vibration platform, creating difficulties in transportation, installation, and leveling, making it challenging to maintain the platform's integrity and impacting the effectiveness of micro-vibration control.

[0005] Therefore, given the limitations of traditional anti-micro-vibration methods, the increasing vibration levels required for precision equipment, and the trend of precision equipment being installed on upper floors, it is essential to develop a high-performance anti-micro-vibration base structure system that improves parameters such as damping coefficient and stiffness while reducing weight. At the same time, designing a modular anti-micro-vibration base that facilitates transportation and installation and ensures the integrity of the base is also indispensable. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this invention provides a modular, lightweight, high-performance anti-vibration base, comprising:

[0007] Multiple base units are assembled sequentially, each base unit including a base panel and multiple support columns located below the base panel;

[0008] The multiple support columns include at least two types: solid support columns and hollow support columns; each pair of base panels is assembled using assembly components.

[0009] In some embodiments, the base panel has a panel extension area on opposite sides. The panel extension area is a base panel area without support columns. The panel extension areas of every two base panels are assembled by assembly components.

[0010] In some embodiments, the assembly component is an I-beam, including a middle web, an upper flange, and a lower flange. The central cavities on both sides of the I-beam respectively enclose the panel extension areas of the left and right base panels, and the sides of the middle web are closely attached to the sides of the panel extension areas of the base panels.

[0011] In some embodiments, mounting holes are reserved on the panel extension area and the assembly component, and bolts are used to fix the panel extension area of ​​the base panel and the lower flange plate of the assembly component through the reserved mounting holes from top to bottom.

[0012] In some embodiments, solid support columns are arranged on the assembly area side of each base unit, while solid and hollow support columns are arranged alternately in the horizontal and vertical directions in other areas.

[0013] In some embodiments, the central web of the assembly component is filled and bonded to the panel extension area of ​​the two side base panels using structural adhesive, and the lower flange is closely attached to multiple solid support columns of the two side base panels.

[0014] In some embodiments, the height of the base panel is 1 / 3 of the height of the anti-vibration base, and the height of the solid support column and the hollow support column is 2 / 3 of the height of the anti-vibration base.

[0015] In some embodiments, the solid support column is a solid concrete support column, and the hollow support column is a hollow concrete support column with a cavity in the middle, wherein the cavity of the hollow support column is filled with granular damping material.

[0016] In some embodiments, the base panel is provided with a double-layer steel mesh, and the solid support column and the hollow support column are provided with column steel mesh.

[0017] Another embodiment of the present invention provides a method for using a modular, lightweight, high-performance anti-vibration base, which employs the anti-vibration base as described above and includes the following steps:

[0018] The base panel, solid support columns, and hollow support columns are tied together with steel mesh, formwork is erected, and concrete is poured as a whole.

[0019] After a period of curing, grind the surface except for the column base and apply anti-static epoxy decorative coating evenly.

[0020] The assembled components are processed to the required dimensions in the factory, then rust-removed and polished. The outer surfaces of the upper and lower flange plates are coated with anti-static epoxy decorative coating, and the coating is applied evenly.

[0021] The anti-micro-vibration base is fabricated and transported to the site. After the transport, structural adhesive is applied to both sides of the web plate in the middle of the assembled component. The extended areas of the two base panels are installed to the cavities on both sides of the assembled steel component. The bolt sleeves are placed in the reserved installation holes, the bolt connectors are inserted, and the bolt connectors are tightened.

[0022] Apply antistatic epoxy decorative coating evenly to the surface of the bolted connections.

[0023] Clean the installation area of ​​the base, use structural adhesive to attach the column base to the ground, and make appropriate adjustments.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The modular, lightweight, high-performance anti-vibration base provided by this invention reduces the weight of the anti-vibration base while ensuring stiffness and damping characteristics, thus ensuring good anti-vibration effect and expanding the applicable scenarios of the anti-vibration base. The modular anti-vibration base provided by this invention ensures consistent vibration response of large-volume bases without affecting the anti-vibration effect, and facilitates processing, manufacturing, transportation, and installation.

[0026] The modular, lightweight, high-performance anti-micro-vibration platform provided by this invention significantly reduces the weight of the platform while ensuring its rigidity and damping performance, resulting in excellent anti-micro-vibration performance.

Therefore, they should not be construed as limitations on this invention.

[0046] Referring to Figures 1-6, an embodiment of the present invention provides a modular, lightweight, high-performance anti-micro-vibration base, comprising: multiple base units that are sequentially assembled, each base unit including a base panel 1 and multiple support columns located below the base panel 1; wherein, the multiple support columns include at least two types of support columns: solid support columns 2 and hollow support columns 3; each pair of base panels 1 is assembled using assembly components 4. In this embodiment, the base panel 1 is a rectangular plate, and the solid support columns 2 and hollow support columns 3 are rectangular columns. The base panel 1, solid support columns 2, and hollow support columns 3 are made of C30 concrete. In this embodiment, the hollow support columns are either completely hollow or partially hollow.

[0047] The base panel 1 has panel extension areas on opposite sides. These extension areas are areas of the base panel 1 without supporting columns. Each pair of base panel 1 panel extension areas are assembled using assembly components 4. The assembly component 4 is an I-beam, including a central web, an upper flange, and a lower flange. The central cavities on both sides of the I-beam respectively enclose the panel extension areas of the left and right base panels 1. The central web is tightly attached to the sides of the panel extension areas of the base panel 1.

[0048] In this embodiment, multiple base panels 1 can be spliced ​​and extended in one direction (as shown in Figure 1, which is the main case described in this invention). It is worth noting that multiple base panels 1 in this invention can also be spliced ​​and extended in two mutually perpendicular directions (as shown in Figure 2), wherein the panel extension areas of each pair of adjacent base panels 1 are assembled by the splicing component 4.

[0049] In this embodiment, mounting holes are pre-drilled at the locations where bolt connectors 5 need to be installed on the panel extension area and the assembly component 4. During installation, bolt sleeves are placed in the mounting holes for the installation and adjustment of bolt connectors 5. Bolt connectors 5 are used to pass through the pre-drilled mounting holes from top to bottom through the upper flange plate of the assembly component 4, fixing the panel extension area of ​​the base panel 1 and the lower flange plate of the assembly component 4. The materials used for the assembly steel components and bolt connectors 5 are steel.

[0050] In this embodiment, solid support columns 2 are arranged on the assembly area side of each base unit. In other areas, solid support columns 2 and hollow support columns 3 are arranged alternately in the horizontal and vertical directions, with three support columns arranged per meter. Usually, three support columns are arranged per meter. If the equipment is heavy and the anti-vibration level is high, the interval size can be reduced.

[0051] In this embodiment, the central web of the assembly component 4 is bonded to the extended areas of the panels on both sides of the base panel 1 using structural adhesive. The lower flange is tightly attached to multiple solid support columns 2 on both sides of the base panel 1. The height of the base panel 1 is 1 / 3 of the height of the anti-vibration base, and the height of the solid support columns 2 and the hollow support columns 3 is 2 / 3 of the height of the anti-vibration base.

[0052] In this embodiment, the solid support column 2 is a solid concrete support column, and the hollow support column 3 is a hollow concrete support column with a cavity in the middle. The cavity of the hollow support column 3 is filled with a particle damping body 6, wherein the particle damping body 6 is made of flexible particles such as polyurethane particles and rubber particles. In this embodiment, the base panel 1 and all the solid support columns 2, hollow support columns 3 and particle damping bodies 6 arranged below form a whole.

[0053] In this embodiment, the base panel 1 is internally provided with a double-layer steel mesh 7, and the solid support column 2 and hollow support column 3 are internally provided with column steel mesh 8. For example, referring to Figure 6, the hollow support column 3 is provided with column steel mesh 8. In this embodiment, the double-layer steel mesh 7 and column steel mesh 8 can be reinforced as needed, for example, according to parameters such as load and bearing capacity. In this embodiment, the steel mesh 7 is a cross-shaped steel mesh; the column steel mesh consists of 8 continuous bars and 8 round stirrups.

[0054] The base panel 1, solid support column 2, hollow support column 3, assembly component 4, and bolt connector 5 provided in this embodiment are decorated with anti-static epoxy, with an epoxy surface thickness of not less than 2mm and uniform coating.

[0055] In this embodiment, each unit of the anti-micro-vibration base is fabricated as a whole, transported, and then assembled, installed, and debugged on site. The solid support column 2, hollow support column 3, and granular damping body 6 are bonded to the ground using structural adhesive.

[0056] In this embodiment, the specifications and dimensions of all components are adjusted according to the usage requirements. The arrangement positions of the solid support column 2 and the hollow support column 3 can be adjusted according to the usage requirements and arrangement principles.

[0057] Another embodiment of the present invention provides a specific design method for an assemblable, lightweight, high-performance anti-vibration base, as detailed below:

[0058] The overall base dimensions are determined based on the equipment dimensions, and the dimensions of each base panel 1 are then determined based on the overall base dimensions. Specifically, for example, if the processing equipment has dimensions of 1500*7500mm, then the overall base dimensions are 2000*8000mm. The overall base can be divided into two units, with each unit's base panel 1 having dimensions of 2000*4000mm.

[0059] The height of the base platform is determined based on the height of the surrounding raised floor, which in turn determines the height of the base panel 1, solid support column 2, and hollow support column 3. Specifically, the height of the surrounding raised floor is typically 600mm or 800mm. If the surrounding raised floor height is 600mm, the height of the anti-vibration base platform is determined to be 600mm, resulting in a base panel 1 height of 200mm and solid support column 2 and hollow support column 3 heights of 400mm. The height of base panel 1 is 1 / 3 of the height of the anti-vibration base platform, and the heights of solid support column 2 and hollow support column 3 are 2 / 3 of the height of the anti-vibration base platform.

[0060] The planar dimensions and spacing of solid support columns 2 and hollow support columns 3 are determined based on the upper load of the foundation and the vibration damping level, which in turn determines the reinforcement details of the double-layer steel mesh 7 and column steel mesh 8. Specifically, for example, based on the equipment weight and vibration damping level, the planar dimensions of solid support columns 2 and hollow support columns 3 are 200*200 mm, and the hollow planar dimensions of hollow support column 3 are 100*100 mm. For heavier equipment and higher vibration damping levels, the planar dimensions of solid support columns 2 and hollow support columns 3 can be increased. Typically, three support columns are arranged per meter. For heavier equipment and higher vibration damping levels, the spacing can be reduced. Reinforcement is calculated based on the weight of the precision equipment. For example, the foundation panel 1 may be equipped with a double-layer, bidirectional φ8@150 steel mesh 7, and solid support columns 2 and hollow support columns 3 may be equipped with 6 φ18; φ8@100 column steel mesh 8.

[0061] The specifications and dimensions of the assembled component 4 and bolted connector 5 are determined based on the upper load of the foundation, the spacing of the support columns, and the dimensions of the foundation panel 1. Specifically, the length of the assembled steel component is determined based on the planar dimensions of each unit foundation panel 1; as mentioned above, the length of the assembled component 4 is 2000mm. Based on the upper load of the foundation, the thickness of the web and flange plates of the assembled steel component and the specifications of the bolted connector 5 are calculated. For example, the thickness of the middle web and flange plates of the assembled steel component is taken as 10mm, and M24 bolts are used for the bolted connector 5. The length of the flange plate of the assembled steel component is the spacing between the solid support column 2 and the hollow support column 3, such as 250mm.

[0062] Another embodiment of the present invention provides a method for using a modular, lightweight, high-performance anti-vibration base, which employs the anti-vibration base as described above and includes the following steps:

[0063] The base panel 1, solid support column 2, and hollow support column 3 are tied together with steel mesh, formwork is erected, and concrete is poured as a whole.

[0064] After a period of curing, such as 28 days, grind the surface except for the column base and apply anti-static epoxy decoration. The epoxy coating thickness should be no less than 2mm and applied evenly.

[0065] Assemble component 4 and the components processed in the factory to the required size are rust-removed and polished. The outer surfaces of the upper and lower flange plates are coated with anti-static epoxy decoration with an epoxy thickness of not less than 2mm and evenly coated.

[0066] The anti-micro-vibration base is fabricated and transported to the site. After the transport, structural adhesive is applied to both sides of the web plate in the middle of the assembly component 4. The extended areas of the two base panels 1 are installed to the cavities on both sides of the assembly steel component. The bolt sleeves are placed in the reserved installation holes, the bolt connectors 5 are inserted, and the bolt connectors 5 are tightened.

[0067] Apply anti-static epoxy coating to the surface of bolted connector 5. The epoxy coating thickness shall be no less than 2mm and the coating shall be uniform.

[0068] Clean the installation area of ​​the base, use structural adhesive to attach the column base to the ground, and make appropriate adjustments.

[0069] The modular, lightweight, high-performance anti-micro-vibration platform provided by this invention is lightweight, with a mass significantly smaller than existing platforms while meeting the required anti-micro-vibration level and effect. It is high-performance, possessing high stiffness, and incorporates particle damping to enhance damping characteristics, resulting in a platform that simultaneously exhibits high stiffness and high damping, thus improving anti-micro-vibration effectiveness. Furthermore, this invention provides a platform panel assembly node. Existing large platforms typically combine smaller platforms together, using a frame or partially connected platform structure, which makes it difficult to guarantee platform integrity and vibration consistency, affecting anti-micro-vibration effectiveness. The proposed platform panel assembly method ensures vibration consistency across the platform surface, guaranteeing consistent vibration performance even for ultra-large platforms.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention. Industrial application

After the overall base is disassembled into unit bases, they can be uniformly manufactured and processed in the factory, facilitating transportation and installation, reducing construction costs, and shortening the installation period. The bases can be flexibly arranged according to different anti-micro-vibration requirements and application scenarios, have high load-bearing capacity, and are widely applicable, meeting most needs.
