Description

Technical Field

[0001] This invention relates to the field of cleanrooms, specifically to a BIM-based modular installation structure and construction method for cleanrooms. Background Technology

[0002] Cleanrooms, as strictly controlled enclosed spaces, remove dust, microorganisms, bacteria, and other impurities from the air, providing a dust-free, pollution-free, and highly clean environment for various high-precision and high-requirement manufacturing and R&D processes. The construction of cleanrooms not only improves product quality and yield but also enhances the working environment for employees and strengthens a company's competitiveness. With technological advancements, industries such as high-end manufacturing, biomedicine, and semiconductors are placing even higher demands on the cleanliness of their production and R&D environments. As the core space for controlling airborne dust, microorganisms, and other impurities, the construction quality of cleanrooms directly impacts product precision, yield, and the working environment for employees.

[0003] Traditional cleanroom design relies on two-dimensional drawings and experience-driven approaches, leading to problems such as information silos, low efficiency in professional collaboration, and frequent design conflicts. This results in extended construction cycles, increased costs, and difficulty in accurately meeting high-precision environmental control requirements. In recent years, modular construction technology has demonstrated significant advantages in the cleanroom field due to its factory prefabrication and on-site assembly characteristics. Current modular installation technology for cleanrooms typically involves breaking down the cleanroom's walls, ceilings, pipes, and equipment into standardized functional modules, which are then manufactured with high precision in the factory and transported to the site for rapid assembly. However, the piping and support frames are usually designed as separate units, requiring on-site step-by-step construction, reducing construction efficiency and safety. Furthermore, when connecting adjacent modules, multiple connection points typically need to be independently tightened sequentially, further reducing construction efficiency.

[0004] Against this backdrop, there is an urgent need to optimize the entire process of cleanroom design and installation through digital technologies (such as BIM) and modular design, in order to meet the real needs of rapid industrial upgrading. Summary of the Invention

[0037] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 11 As shown, this invention proposes a BIM-based modular installation structure for cleanrooms, including a prefabricated exterior wall 1. The prefabricated exterior wall 1 is a standardized prefabricated module of the cleanroom enclosure structure. It is designed by splitting the BIM model, prefabricated in the factory, and assembled on-site in a modular manner. The prefabricated exterior wall 1 includes several unit structures, and adjacent unit structures are connected by conventional connection structures such as bolts.

[0039] A hanging module is installed at the top of the inner cavity of the prefabricated exterior wall 1. The hanging module includes several hanging rods 2 connected to the top of the inner cavity of the prefabricated exterior wall 1. The hanging rods 2 are connected to the top of the inner cavity of the prefabricated exterior wall 1 using conventional connection structures such as bolts or welding. The bottom of both ends of the hanging rods 2 are connected to the bottom of the inner cavity of the prefabricated exterior wall 1 through support columns 3. The support columns 3 support the hanging rods 2, thereby enhancing the structural stability of the hanging module. Two adjacent hanging rods 2 are connected by a connecting plate 7. The connecting plate 7 can evenly transfer the load to multiple hanging rods, avoiding deformation or damage caused by excessive stress at a single point, and enhancing the overall stability and structural strength of the hanging module.

[0040] The bottom of the straight section of the hanging module is equipped with a pipe rack module 5 and a ceiling module with cleanroom auxiliary equipment 10 installed. The pipe rack module 5 is located above the ceiling module. The inner cavity of the prefabricated outer wall 1 is equipped with a prefabricated shielding plate 6. The prefabricated shielding plate 6 and the ceiling module form the inner wall of the cleanroom. The hanging module and the pipe rack module are located between the prefabricated outer wall 1 and the prefabricated inner wall to improve the aesthetics of the cleanroom.

[0041] The pipe rack module 5 includes a pipe rack body 17 connected to the hanging module via a quick-release structure 1. The quick-release structure 1 includes a male connector 16 and a female connector 9 connected to the top of the pipe rack body 17. The bottom of the female connector 9 is provided with a through hole adapted to the top of the male connector 16. The hanging rod 2 is provided with a connecting hole 11 adapted to the top of the male connector 16. The top of the connecting hole 11 is connected to the bottom of the female connector 9, and the connecting hole 11 and the through hole are aligned. The side of the through hole is connected to a plug 15 via a second spring 14. 5 is movably connected to the inner cavity of the female connector 9. Under the action of the rebound force of the second spring 14, the insert block 15 can move in the horizontal direction. Above the through hole, a limiting block 13 is connected through the first spring 12. The limiting block 13 is movably connected to the inner cavity of the female connector 9. Under the action of the rebound force of the first spring 12, the limiting block 13 can move in the vertical direction. When the female connector 9 and the male connector 16 are separated, the limiting block 13 can limit the insert block 15. The top of the male connector 16 is provided with a socket 25 that is adapted to the insert block 15.

[0042] With the quick-release structure, during installation, the male connector 16 of the pipe rack module 5 can be inserted into the inner cavity of the female connector 9 through the connecting hole 11 and the through hole. During the insertion process, the male connector 16 squeezes the limiting block 13, causing the limiting block 13 to gradually move away from the insert block 15. When the insertion hole 25 is aligned with the insert block 15, the insert block 15 can be inserted into the insertion hole 25 under the action of the rebound force of the second spring 14, thereby realizing the quick connection between the pipe rack module 5 and the hanging module. Furthermore, the male connector 16 and the pipe rack body 17 are connected in a detachable manner, which facilitates the removal of the pipe rack body 17.

[0043] A support plate 27 is provided at one end of the inner cavity of the pipe rack body 17. An interlocking structure is movably connected to the top of the support plate 27. The interlocking structure includes a pipe support frame 22 that contacts the top of the support plate 27 and a linkage plate 24 located above the pipe support frame 22. The support plate 27 supports the pipe support frame 22. The top of the pipe support frame 22 is provided with a lower clamping groove 28 that is adapted to the cleanroom pipes. A pipe positioning frame 21 is provided in the middle of the inner cavity of the pipe rack body 17. A limit plate 20 is provided at the other end of the inner cavity of the pipe rack body 17. The pipe support frame 22, the pipe positioning frame 21 and the limit plate 20 form a support module adapted to the cleanroom pipes. The cleanroom pipes and the pipe rack module 5 are pre-assembled through a BIM model. The cleanroom pipes are connected to the pipe positioning frame 21. The inner side of the limit plate 20 is provided with a placement groove adapted to the cleanroom pipes, and the outer side of the limit plate 20 is provided with a positioning groove adapted to the pipe support frame 22.

[0044] The bottom of the linkage plate 24 is detachably connected to an upper clamping plate 32 adapted to the cleanroom pipeline. The linkage plate 24 is connected to the pipeline support frame 22 by a third bolt 31, and the third bolt 31 is movably connected to the linkage plate 24. The third bolt 31 is threadedly connected to the pipeline support frame 22. During the construction of the cleanroom, when the construction personnel tighten the third bolt 31, the third bolt 31 can drive the linkage plate 24 to move down until the end of the linkage plate 24 is tightly fitted with the end of the pipeline support frame 22. At this time, the cooperation of the upper clamping plate 32 and the lower clamping groove 28 realizes the clamping and fixing of the cleanroom pipeline. Both the lower clamping groove 28 and the upper clamping plate 32 are provided with sealing gaskets on their inner walls. The sealing gaskets improve the sealing between the upper clamping plate 32 and the lower clamping groove 28 and the cleanroom pipeline, and prevent fluid leakage.

[0045] The upper clamping plate 32 is connected to the pipe support frame 22 via a quick-release structure two. The quick-release structure two includes a fixing post 29 connected to the top of the pipe support frame 22 and a connecting housing 35 connected to the top of the upper clamping plate 32. The bottom of the inner cavity of the connecting housing 35 is provided with an insertion hole 36 adapted to the fixing post 29. Both sides of the bottom end of the insertion hole 36 are connected to locking rods 38 by a third spring 37. The locking rods 38 are in a movable connection with the connecting housing 35. One end of the locking rods 38 extends into the inner cavity of the connecting housing 35, and one end of the two locking rods 38 forms an inverted conical groove adapted to the fixing post 29. The other end of the locking rods 38 extends to the outside of the connecting housing 35. The top of the fixing post 29 is provided with a locking rod. The 38-adaptive limiting groove, through the setting of the quick-release structure two, when the linkage plate 24 drives the upper clamping plate 32 to move down, the upper clamping plate 32 drives the connecting housing 35 to move down, and the fixing post 29 can be inserted into the inner cavity of the connecting housing 35. During the insertion process, the fixing post 29 squeezes one end of the locking rod 38. Under the action of the squeezing force, the two locking rods 38 are in a state of moving away from each other. When the limiting groove and the locking rod 38 are aligned, under the action of the rebound force of the third spring 37, one end of the locking rod 38 can be inserted into the limiting groove, realizing the connection between the upper clamping plate 32 and the pipe support frame 22. The upper clamping plate 32 and the pipe support frame 22 can realize the clamping and fixing of the end of the clean room pipe.

[0046] The top of the connecting housing 35 is provided with a positioning hole 39, and the top of the linkage plate 24 is provided with a moving groove 34. The inner cavity of the moving groove 34 is movably connected to a moving rod 30. The side of the moving rod 30 near the connecting housing 35 is provided with a positioning rod 40 that matches the positioning hole 39. The moving rod 30 is connected to the linkage plate 24 by a second bolt 33. The second bolt 33 is movably connected to the moving rod 30. When the construction personnel tighten the second bolt 33, the second bolt 33 can drive the moving rod 30 to move. The moving rod 30 drives the positioning rod 40 connected to it to move. When the positioning rod 40 is separated from the positioning hole 39, the linkage plate 24 and the upper clamping plate 32 can be quickly disassembled.

[0047] As described above, the linkage plate 24 and the upper clamping plate 32 can be quickly assembled and disassembled. When the linkage plate 24 and the upper clamping plate 32 are connected, the movement of the linkage plate 24 can realize the synchronous movement of multiple upper clamping plates 32, improving the construction efficiency of the cleanroom. When the linkage plate 24 and the upper clamping plate 32 are separated, the staff can remove individual cleanroom pipes, which is convenient for repairing and replacing cleanroom pipes in specific locations.

[0048] The pipe support frame 22 is connected to one end of the pipe support body 17 via a first bolt 26 and a locking post 23. The first bolt 26 is movably connected to the pipe support frame 22. The other end of the pipe support body 17 is provided with a threaded hole 19 that matches the first bolt 26 and a locking hole 18 that matches the locking post 23. With the first bolt 26 in place, during construction of the cleanroom, the locking hole 18 of another pipe support module 5 is aligned with the locking post 23, and the threaded hole 19 is aligned with the first bolt 26. When the construction personnel tighten the first bolt 26, the pipe support frame 22 can be moved. The pipe support frame 22 is connected to the third bolt 3. 1. Drive the linkage plate 24 to move synchronously until the pipe support frame 22 is located in the positioning groove and is tightly attached to the limiting plate 20. At this time, the upper clamping plate 32 and the lower clamping groove 28 are located between two cleanroom pipes that are tightly attached to each other, which makes it convenient to use the upper clamping plate 32 and the lower clamping groove 28 to clamp and fix the two cleanroom pipes that are tightly attached to each other. When the first bolt 26 is screwed, the first bolt 26 can be in a threaded connection state with the threaded hole 19 on the adjacent pipe rack body 17. The locking post 23 can be inserted into the locking hole 18 on the adjacent pipe rack body 17 to realize the connection of the two adjacent pipe rack bodies 17.

[0049] As described above, the interlocking structure enables the installation of two closely fitted cleanroom pipes and two adjacent pipe rack modules 5, simplifying the construction process, improving the efficiency of cleanroom construction, and allowing multiple cleanroom pipes to be connected synchronously, further improving the efficiency of cleanroom construction and facilitating the control of construction quality.

[0050] The ceiling module includes ceiling panels 4. Two adjacent ceiling panels 4 are tightly interlocked to form a continuous and flat ceiling surface. Each ceiling panel 4 has a pre-set mounting position at the top and is vertically connected to the upper hanging rod 2 through a hanging rod 8.

[0051] In practical application, a lower clamping groove 28 can be set on the pipe positioning frame 21 at a specific location, and a linkage plate 24 can be set above the pipe positioning frame 21 at a specific location. An upper clamping plate 32 can be set at the bottom of the linkage plate 24. The upper clamping plate 32 and the linkage plate 24 are detachably connected. The upper clamping plate 32 and the pipe positioning frame 21 are connected through a quick-release structure. This setting can improve the connection speed between the cleanroom pipes and the pipe rack module 5, thereby further improving the construction efficiency.

[0052] As can be seen from the above description, during construction, the quick-release structure 1, quick-release structure 2 and interlocking structure can improve the construction efficiency of cleanrooms. By using the cleanroom pipe and pipe rack module 5 to pre-assemble on the ground in the factory or construction site through the BIM model, the risk of high-altitude operations can be reduced and the construction safety can be improved.

[0053] This invention proposes a BIM-based cleanroom construction method, applying a BIM-based modular installation structure to the cleanroom construction method. The cleanroom construction method specifically includes the following steps:

[0054] Step 1: Based on the functional requirements of the cleanroom, the cleanroom is divided into standardized and prefabricated modular installation structures.

[0055] Step 2: Establish a BIM-based modular installation structure model for the cleanroom;

[0056] Step 3: Conduct virtual construction simulation using BIM model, optimize construction steps, and formulate cleanroom construction process and specifications;

[0057] Step 4: Based on the BIM model, the cleanroom components are broken down and digital processing drawings are generated. The factory then prefabricates the components according to the drawings.

[0058] Step 5: According to the drawings, construct the prefabricated exterior wall 1, hanging module, pipe rack module 5, ceiling module, and prefabricated shielding panel 6 in sequence. Before construction, the pipe rack module 5 should have its pipes installed and fixed on the factory or on-site. During construction, it should be lifted to the designated position as a whole, and after installation with the hanging rod 2 using the quick-release structure, the two cleanroom pipes and the two adjacent pipe rack modules 5 should be installed using the interlocking structure. Before construction, the ceiling module should have its cleanroom auxiliary equipment 10 connected to the ceiling panel 4 in the factory. During construction, the ceiling module should be assembled on the ground and then lifted to the designated position as a whole using lifting equipment. It should be vertically connected to the hanging rod 2 above using the hanging rod 8.

[0059] As described above, this construction method adopts an integrated layout of cleanroom pipelines and pipe rack modules 5, as well as a construction method of floor assembly and overall installation of ceiling modules, which shortens the time for construction personnel to work at heights, reduces construction difficulty, and improves construction efficiency.

[0060] In summary, when using this BIM-based modular installation structure and construction method for cleanrooms, the construction process is optimized and the construction cycle is shortened during the design phase through BIM technology. At the same time, the reliability and durability of the structure are improved by optimizing the load distribution. During the construction phase, the integrated layout of cleanroom pipelines and pipe rack modules 5 and the construction method of floor assembly and overall installation of ceiling modules shorten the time for construction personnel to work at heights, reduce construction difficulty, and improve construction efficiency and operational safety.
