Description

Technical Field

[0001] This invention relates to the field of ground vibration damping technology, specifically to a micro-vibration damping base that combines a steel plate and a base. Background Technology

[0002] In high-precision manufacturing, precision measurement, and cutting-edge scientific research, extremely high requirements are placed on the micro-vibration control of the equipment operating environment. As a key infrastructure for isolating the transmission of external vibrations, the performance of anti-vibration bases directly determines the positioning accuracy and operational stability of high-end equipment. Currently, the industry commonly uses epoxy resin self-leveling technology to construct the base surface layer, which can meet certain leveling requirements, but still has several significant technical bottlenecks.

[0003] First, epoxy-based materials are inherently brittle. Under long-term loads, temperature changes, or impacts, the surface is prone to micro-cracks or even brittle fracture, affecting not only aesthetics but also potentially weakening overall rigidity and vibration isolation performance, posing a reliability risk. Second, due to limitations in material leveling characteristics and construction processes, the flatness of epoxy self-leveling compounds typically only reaches approximately ±1mm / ㎡, which is insufficient to meet the stringent requirements of increasingly sophisticated ultra-precision equipment for the flatness of mounting surfaces. Third, when equipment requires fixation with numerous anchor bolts, a large number of metal components must be embedded in the epoxy layer. Excessively dense embedded components not only exacerbate the risk of epoxy layer cracking due to stress concentration but also easily cause interference during construction, leading to inaccurate positioning, construction difficulties, and low finished product yield, thus restricting the flexibility of design and layout. Finally, epoxy self-leveling processes can only form a single continuous plane and cannot build installation planes of different heights on the same base. Modern composite process equipment is often composed of multiple modules, each with different requirements for the height of the installation reference surface. Traditional epoxy bases cannot achieve this kind of complex three-dimensional shape, forcing equipment manufacturers to use temporary measures such as additional pads, which introduces secondary installation errors and instability.

[0004] Therefore, there is an urgent need for a new type of anti-micro-vibration base structure to fundamentally overcome the performance defects of epoxy materials and achieve higher planar accuracy, structural reliability and installation flexibility. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a micro-vibration-resistant base that combines a steel plate and a base.

[0006] The present invention provides the following technical solution: a micro-vibration prevention base that combines a steel plate and a base, wherein the base adopts an upper and lower composite layered structure, comprising a stainless steel panel layer and a concrete base layer from top to bottom; The stainless steel panel layer and the concrete base layer are rigidly connected by an anchoring system embedded in the concrete to form an integral load-bearing unit; the upper surface of the stainless steel panel layer is constructed as an integrated composite functional surface containing multiple installation planes of different heights.

[0007] Preferably, the concrete base layer is made of high-strength concrete and serves as the main load-bearing and mass block of the base, providing sufficient mass inertia to suppress and dissipate vibration energy.

[0008] Preferably, the anchoring system consists of pre-embedded threaded steel bars and a positioning base plate.

[0009] Preferably, multiple threaded steel bars are arranged evenly in a matrix, with their lower parts pre-embedded in the concrete base layer and their upper bent surfaces welded to the stainless steel panel layer.

[0010] Preferably, a base plate can be welded to the bottom of the threaded steel bar to enhance its pull-out strength and stability in concrete.

[0011] Preferably, the stainless steel panel layer is composed of a large area of ​​SUS304 stainless steel plate, which has reserved holes for equipment installation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) Significantly improves the flatness, rigidity, and durability of the base surface, completely eliminating the risk of brittle cracking; Stainless steel panels replace the traditional epoxy self-leveling coating as the equipment mounting surface. Stainless steel has inherent rigidity and good toughness, avoiding the inherent brittleness of epoxy materials, and fundamentally eliminating the risk of brittle cracking caused by load, temperature difference, or impact. At the same time, factory machining can easily control the flatness of the mounting surface to a precision level of ±0.1mm / ㎡ or even higher, far exceeding the limits of epoxy construction, providing an extremely stable and reliable installation benchmark for ultra-high precision equipment.

[0013] (2) It achieves an unrestricted and flexible layout of equipment mounting holes, greatly improving design freedom and construction convenience; it abandons the traditional method of pre-embedding metal parts during the casting process. All threaded mounting holes required by the equipment can be precisely secondary-processed on-site or in the factory according to the actual hole positions of the equipment base after the stainless steel panel is in place and leveled. This method completely avoids the mutual interference problem caused by the dense position of pre-embedded parts, and the construction is simple and has a high fault tolerance rate. Users no longer need to compromise the equipment layout due to pre-embedded limitations, realizing true on-demand hole layout, with extremely strong design flexibility and adaptability.

[0014] (3) By welding the pre-embedded threaded steel bars to the upper stainless steel panel and grouting the cavity, a rigid integral composite structure is formed between the concrete base and the stainless steel panel. This connection method is far more robust and reliable than the physical bonding between the epoxy layer and the pre-embedded parts, with a clear force transmission path and significantly improved overall stiffness and strength. This not only ensures the structural stability of the base itself, but its higher overall quality and rigidity also help to more effectively suppress and dissipate vibration energy, thereby providing superior anti-micro-vibration performance.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. In order to keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0018] Please see Figure 1 The present invention provides an anti-vibration base, the main body of which is composed of a stainless steel panel layer 1 and a concrete base layer 2.

[0019] First, construct the concrete base layer 2; tie the foundation steel cage and set up the formwork according to the design requirements.

[0020] Multiple pre-embedded threaded steel bars 3 are precisely fixed using a positioning mold to ensure that their verticality and top elevation are initially consistent. Preferably, a positioning base plate 4 can be welded to the bottom end of each threaded steel bar to enhance its anchoring stability.

[0021] Concrete with a strength grade of not less than C50 is used for pouring and vibration, and the concrete pouring surface is slightly lower than the root of the threaded part of the pre-embedded threaded steel bar 3 to leave room for operation. After pouring, it is cured to the design strength; next, the stainless steel panel layer 1 is leveled and installed.

[0022] 4. Using a high-precision level, a perfectly flat reference plane is constructed by finely adjusting the height of each threaded steel bar surface 3. The flatness of this plane can be initially controlled through this leveling process.

[0023] 5. Hoist a rough-machined 35mm thick SUS304 stainless steel plate into place, ensuring its lower surface rests stably on all leveled threaded steel bar surfaces 3; then, perform final connection and finishing.

[0024] 6. Using laser welding, the lower surface of the stainless steel panel 1 is welded to the top of each pre-embedded threaded steel bar 3 to achieve a rigid connection between the upper and lower structures and form an overall load-bearing frame.

[0025] 7. Finally, using the leveled upper surface as a reference, the upper surface of the stainless steel panel 1 is finished by a large gantry milling machine or precision grinding machine in the factory or on site, so that its overall flatness reaches the extremely high requirement of ±0.1mm / ㎡.

[0026] 8. Based on the actual installation drawing of the precision equipment, use drilling and tapping equipment to machine the required equipment installation holes at any position on the precision-machined stainless steel panel 1.

[0027] At this point, a high-precision anti-vibration base integrating multi-height installation functions has been installed.

[0028] The advantages of this embodiment are: By combining innovative processes such as "anchoring zone leveling + welding rigid connection + CNC milling multi-plane machining", not only are some inherent defects of epoxy bases solved in one go, but also the functional limitation of traditional bases that can only provide a single plane is broken through. This achieves a revolutionary breakthrough in integrating multiple high-precision mounting planes on a single base, providing a better installation solution for modern complex and precision equipment.
