Description

Technical Field

[0001] This utility model relates to the field of raised floor technology, specifically to a sealed and shock-absorbing raised floor for clean rooms. Background Technology

[0002] Cleanrooms, also known as clean factories or dust-free rooms, are specially designed rooms that eliminate airborne particles, harmful gases, bacteria, and other contaminants within a defined space. They control factors such as temperature, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within specific requirements. Raised floors are structures that elevate the floor of a cleanroom, allowing equipment and personnel to be positioned away from the ground. Raised floors are available in various materials: all-steel raised floors, aluminum alloy raised floors, composite raised floors, or wood-based raised floors. All-steel raised floors are formed by stamping upper and lower steel plates, with foamed cement or lightweight materials filling the gaps. They offer high mechanical strength, strong load-bearing capacity, and good impact resistance, making them suitable for cleanrooms with high load-bearing requirements.

[0003] CN214090780U discloses a raised floor for use in cleanrooms. The cleanroom includes a fan-filter device and a return air device. The fan-filter device is installed at the top of the cleanroom, drawing in air and delivering filtered air into the cleanroom. The raised floor is installed at the bottom of the cleanroom, and the fan-filter device supplies air into the cleanroom. The raised floor includes several floor units, each unit comprising four columns, a vibration-damping frame, and a floor panel. The vibration-damping frame is square-shaped, and the four columns are of equal height and support the vibration-damping frame. The size of the floor panel matches the size of the vibration-damping frame so that the gap between adjacent floor panels is less than a preset value. Air enters the return air device through the return air holes of the raised floor, and the return air device purifies the recovered air. This raised floor can improve the cleanliness of cleanrooms.

[0004] While the existing technology CN214090780U has many benefits during use, it still has the following problems: its cushioning of the floor is not perfect. Due to heavy objects or people stepping on it, the center of the floor will sink, affecting the overall stability of the floor support. Furthermore, stepping or heavy objects pressing on it will cause the floor to vibrate, affecting the stability of the connection between the floor and the frame. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a sealed and shock-absorbing raised floor for cleanrooms.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A sealed and vibration-damping raised floor for cleanrooms includes a base plate, a support frame, and a guide ring. A support column is provided at the upper end of the base plate, and the support frame is screwed to the outer wall of the upper end of the support column. A storage groove is provided inside the support frame, and the floor body is placed inside the storage groove. A guide ring is slidably installed on the outer side of the support column. A connecting frame distributed in a circular array is welded to the outer wall of the guide ring, and a limit ring is welded to one side of the outer wall of the support column.

[0008] By adopting the above technical solution, the base plate is placed on the floor inside the clean room to level the position of the floor body. The support columns and support frames raise the usable height of the floor body and provide precise positioning for the floor body, which is convenient for construction alignment. At the same time, it protects the edges of the floor body from collision damage. The limiting ring, together with the buffer spring and support plate, can provide multi-point support for the floor body, improve the structural strength of the floor body, and distribute the force on the floor body, reduce the pressure damage to the floor body, and extend the service life of the floor body.

[0009] Specifically, the upper surface of the floor body is at the same level as the upper surface of the support frame, and the floor body is connected to the inner wall of the storage groove by screws.

[0010] By adopting the above technical solution, the floor body is flush with the support frame, avoiding the formation of steps or gaps. The screws maintain the relative positional stability of the floor body inside the storage groove. The screws are threaded through the floor body and connected inside the storage groove, so that the floor body can still be vertically displaced outside the screws by the gap provided by the sealing ring, providing a buffer distance for the floor body.

[0011] Specifically, a sealing ring is bonded and fixed to the lower outer wall of the floor body. The sealing ring has a hollow design inside, and the lower outer wall of the sealing ring is in contact with the lower end of the inner wall of the storage groove.

[0012] By adopting the above technical solution, the hollow sealing ring provides an elastic seal, effectively preventing pollutants carried by the airflow under the floor body from penetrating into the cleanroom working area. When the sealing ring is squeezed by the floor body, it will deform under pressure, reducing the overall height of the sealing ring. Based on the distance the floor body moves to follow the change in the height of the sealing ring, it can alleviate the vibration generated when the floor body is impacted.

[0013] Specifically, a support plate is screwed to the outer wall of the connecting frame at the end away from the guide ring. The support plate is located at the lower end of the floor body, and the support plate is screwed to the floor body.

[0014] By adopting the above technical solution, the support plate forms a multi-point support structure at the lower end of the floor body. By dispersing the pressure, it avoids excessive local load that could cause the floor body to crack or collapse, thereby improving the load-bearing capacity and deformation resistance of the floor body and thus extending the service life of the base plate.

[0015] Specifically, the limiting ring is located at the lower end of the guide ring, and a buffer spring is provided at the upper end of the limiting ring. The buffer spring is sleeved on the outside of the support column, and the guide ring is elastically connected to the limiting ring through the buffer spring.

[0016] By adopting the above technical solution, when the floor body moves vertically, it will move the connecting frame and the limiting ring through the support plate. The buffer spring can reduce the vibration amplitude and effectively absorb the vibration generated by equipment operation or personnel walking, ensuring the relative stability of the floor body's position. In addition, the limiting ring prevents the guide ring from excessive displacement and protects the buffer spring from working within its elastic range.

[0017] Specifically, the support columns are arranged in a rectangular array, and the lower outer wall of the support column is connected to the upper outer wall of the base plate with screws.

[0018] By adopting the above technical solution, the multi-point support columns ensure the stability of the support frame in use, and the screws ensure the connection strength between the support columns and the base plate.

[0019] The beneficial effects of this utility model are:

[0020] 1. The present invention relates to a sealed and shock-absorbing raised floor for cleanrooms. The sealing ring effectively prevents pollutants carried by the airflow below the floor body from penetrating into the cleanroom working area. When the sealing ring is squeezed by the floor body, it will deform under pressure, reducing the overall height of the sealing ring. Based on the movement distance of the floor body following the change in the height of the sealing ring, the vibration amplitude can be reduced by the buffer spring. It can effectively absorb the vibration generated by equipment operation or personnel movement, ensure the relative stability of the floor body in use, and alleviate the vibration generated when the floor body is impacted.

[0021] 2. The sealed and shock-absorbing raised floor for cleanrooms described in this utility model, with its limiting ring, buffer spring and support plate, can provide multi-point support for the floor body, improve the structural strength of the floor body, and disperse the force on the floor body, reduce the pressure damage to the floor body and extend the service life of the floor body.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention discloses a sealed and shock-absorbing raised floor for cleanrooms, comprising a base plate 1, a support frame 2, and a guide ring 3. A support column 11 is provided at the upper end of the base plate 1, and the support frame 2 is screwed to the outer wall of the upper end of the support column 11. A storage groove 21 is provided inside the support frame 2, and the floor body 22 is placed inside the storage groove 21. A guide ring 3 is slidably installed on the outer side of the support column 11, and a connecting frame 31 distributed in a circular array is welded to the outer wall of the guide ring 3. A limit ring 12 is welded to one side of the outer wall of the support column 11.

[0031] In use, the base plate 1 is placed on the floor inside the clean room to level the position of the floor body 22. The support column 11 and support frame 2 raise the working height of the floor body 22 and provide precise positioning for the floor body 22, which is convenient for construction alignment. At the same time, it protects the edges of the floor body from collision damage. The limiting ring 12, together with the buffer spring 13 and support plate 32, can provide multi-point support for the floor body 22, improve the structural strength of the floor body 22, and distribute the force on the floor body 22, reduce the pressure damage to the floor body 22, and extend the service life of the floor body 22.

[0032] To maintain the usage location, for example, such as Figure 2As shown, the upper surface of the floor body 22 is at the same level as the upper surface of the support frame 2, and the floor body 22 is connected to the inner wall of the storage groove 21 by screws.

[0033] During use, the floor body 22 is flush with the support frame 2 to avoid forming steps or gaps. The relative position stability of the floor body 22 inside the storage groove 21 is maintained by screws. The screws pass through the floor body 22 and are threaded into the storage groove 21, so that the floor body 22 can still be vertically displaced outside the screws by the gap provided by the sealing ring 23, providing a buffer distance for the floor body 22.

[0034] For sealing purposes, exemplarily, such as Figure 3 As shown, a sealing ring 23 is glued and fixed to the lower outer wall of the floor body 22. The sealing ring 23 has a hollow design inside, and the lower outer wall of the sealing ring 23 is in contact with the lower end of the inner wall of the storage groove 21.

[0035] When in use, the hollow sealing ring 23 provides an elastic seal, effectively preventing pollutants carried by the airflow below the floor body 22 from penetrating into the cleanroom working area. When the sealing ring 23 is squeezed by the floor body 22, it will deform under pressure, reducing the overall height of the sealing ring 23. Based on the movement distance of the floor body 22 following the height change of the sealing ring 23, the vibration generated when the floor body 22 is impacted can be mitigated.

[0036] To ensure connection strength, for example, such as Figure 4 As shown, a support plate 32 is screwed to the outer wall of the connecting frame 31 away from the guide ring 3. The support plate 32 is located at the lower end of the floor body 22, and the support plate 32 is screwed to the floor body 22.

[0037] During use, the support plate 32 forms a multi-point support structure at the lower end of the floor body 22. By dispersing the pressure, it avoids excessive local load that could cause the floor body 22 to crack or collapse, thereby improving the load-bearing capacity and deformation resistance of the floor body 22 and thus extending the service life of the base plate 1.

[0038] To mitigate the impact, for example, such as Figure 5 As shown, the limiting ring 12 is located at the lower end of the guide ring 3, and a buffer spring 13 is provided at the upper end of the limiting ring 12. The buffer spring 13 is sleeved on the outside of the support column 11, and the guide ring 3 is elastically connected to the limiting ring 12 through the buffer spring 13.

[0039] When the floor body 22 moves vertically during use, it will carry the connecting frame 31 and the limiting ring 12 through the support plate 32. The buffer spring 13 can reduce the vibration amplitude and effectively absorb the vibration generated by equipment operation or personnel walking, ensuring the relative stability of the floor body 22 in use. The limiting ring 12 prevents the guide ring 3 from excessive displacement and protects the buffer spring to work within its elastic range.

[0040] To maintain the usage location, for example, such as Figure 2 As shown, the support columns 11 are distributed in a rectangular array, and the lower outer wall of the support column 11 is connected to the upper outer wall of the base plate 1 with screws.

[0041] During use, the multi-point support columns 11 ensure the stability of the support frame 2 in its position, and the screws ensure the connection strength between the support columns 11 and the base plate 1.

[0042] In use, the base plate 1 is placed horizontally on the cleanroom floor and fixed with anchor bolts to provide a stable reference for the upper support frame 2. The floor body 22 is placed into the storage groove 21 of the support frame 2, and the position is adjusted with the sealing ring 23 so that its upper end is flush with the support frame 2. At this time, the sealing ring 23 at the lower end of the floor body 22 is in initial contact with the bottom of the storage groove 21, but has not yet been deformed by pressure. The lower end of the sealing ring 23 is attached to the bottom of the inner wall of the storage groove 21 to form an initial seal. At this time, the hollow structure inside the sealing ring 23 remains in its natural state, reserving deformation space for subsequent shock absorption and buffering.

[0043] The floor body 22 is fixed to the inner wall of the storage groove 21 by screws: the screws pass through the floor body 22 and are screwed into the matching threaded holes in the inner wall of the storage groove 21. The screw threads are only present in the threaded hole, while the rest of the parts are designed to be smooth. Therefore, the floor body 22 can move vertically under the guidance of the screws.

[0044] When personnel or equipment apply pressure to the floor, the floor body 22, through the support plate 32, drives the guide ring 3 to slide downward along the support column 11, compressing the buffer spring 13. At the same time, the sealing ring 23 deforms under pressure, and the hollow structure contracts, absorbing vibration energy. After the pressure is released, the buffer spring 13 returns to its original position, pushing the guide ring 3 upward, causing the floor body 22 to return to its original position, and the sealing ring 23 elastically recovers, maintaining a sealed state.

All components in this utility model are known to those skilled in the art, and their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
