[0016] S2: After the fixing column is installed, the staff moves the two ceiling frame bodies to the top of the support plate, to ensure that the ceiling frame bodies are preliminarily in a fixed state;

[0017] S3: The staff pushes the ceiling frame body, so that the ceiling frame body is in contact with the two push rods on one side of the fixing block in sliding cooperation, and with the continuous pushing of the ceiling frame body, the push rod moves to the inside of the fixing block, thereby driving the gear plate at the end of the push rod extending to the inside of the fixing block to move synchronously, the movement of the gear plate drives the gear to rotate, the threaded rod arranged on one side of the gear rotates synchronously with the gear, and under the rotating action of the threaded rod, the square sliding block slides downward along the two square sliding grooves formed in the inside of the fixing block, the moving plate arranged at one end of the extension of the sliding block moves with the sliding of the sliding block, and the fixing plate at the bottom of the moving plate and the clamping block at the bottom of the fixing plate also move synchronously;

[0018] S4: When the clamping block moves to the inside of the two fixing grooves formed in the inside of the support plate, the clamping block is in contact with the G-shaped rod in sliding cooperation with the bottom of the fixing groove, the continuously moving clamping block drives the G-shaped rod to move downward, and when the G-shaped rod moves away from the surface of the stop plate, the stop plate is released from the limiting; under the elastic force of the spring three, the stop plate drives the pull rod to move toward the clamping block until the pull rod moves into the clamping groove formed in the inside of the clamping block, to fix the clamping block and thereby fix the ceiling frame body, at this time, the ceiling plate can be clamped into the ceiling frame body to complete the installation;

[0020] S6: The worker moves the ceiling frame body, weakens the extrusion force of the push rod, under the elastic restoring force of spring one, the tooth plate moves away from the gear, drives the gear to rotate in the opposite direction, the threaded rod rotates in the opposite direction with the gear, the sliding block slides in the opposite direction along the sliding groove, drives the moving plate, the fixed plate and the clamping block to move upwards until the height of the clamping block is higher than the top of the ceiling frame body;

[0021] S7: After the clamping block is moved upwards to be higher than the top of the ceiling frame body, the worker removes the ceiling frame body from the top of the support plate, and the fixing operation of the ceiling frame body is completed.

[0022] The present application has the following beneficial effects:

[0023] 1: The present application replaces the core fixing function of traditional screws with pure mechanical transmission through the synergistic effect of the clamping device and the fixing device, the worker pushes the ceiling frame body to trigger the movement of the push rod, and then drives the gear to mesh and transmit, drives the threaded rod to rotate and makes the sliding block translate along the sliding groove, and finally forms stable clamping of the ceiling frame body through the moving plate and the fixed plate; at the same time, the clamping block at the bottom of the fixed plate is matched with the clamping of the fixing device in the support plate, which further strengthens the fixing effect, and the ceiling frame body is directly fixed without relying on screws throughout the process, which avoids the risk of loosening caused by screw rust from the root. In addition, the spring drive realizes automatic clamping of the pull rod and automatic resetting of the components during installation, without complex calibration; disassembly only needs to pull the pull rod to release the fixing, which is convenient for local maintenance; the basic components such as fixed column and fixed block can be disassembled and reused, which improves the economy and practicability, and the spring one in the fixed block can maintain the position of the tooth plate stable through the elastic restoring force, which ensures the long-term operation reliability of the transmission structure, effectively improves the durability and stability of the ceiling reinforcement.

[0034] The inside of support plate 23 is equipped with two limit blocks three 30 and two limit blocks four 31, limit block three 30 is slidingly fitted with G-shaped rod 24, limit block four 31 is slidingly fitted with pull rod 12, the inside of fixed block 2 is equipped with two limit blocks one 28 and two limit blocks two 29, limit block one 28 is slidingly fitted with push rod 10, limit block two 29 is rotationally fitted with threaded rod 20, the bottom of ceiling frame main body 1 is fixedly installed with two bottom plates 16, and U-shaped installation slot 15 is formed in bottom plate 16 and ceiling frame main body 1, and adaptive slot 17 is formed in the four corners of ceiling frame main body 1, and ceiling plate is fixedly installed in U-shaped installation slot 15, and fixed column 3 is fixedly installed on the top of fixed block 2, and mounting plate 13 is fixedly installed on the top of fixed column 3, and bolt hole is formed in the four corners of mounting plate 13, and fixed bolt 14 is arranged in bolt hole, and the fixing of mounting plate 13 is realized through bolt hole and fixed bolt 14, and sliding groove 4 is square groove, and sliding block 5 is square block.

[0035] The specific implementation is as follows: first, the staff fixes the fixing column 3 on the top of the fixing block 2, the mounting plate 13 on the top of the fixing column 3, and the four fixing bolts 14 inside the mounting plate 13, and installs the fixing column 3 at the specified position required for construction. The combination of a large-area mounting plate and multiple groups of bolts can disperse the fixing load, ensure the long-term stability of the fixing column 3, and provide reliable foundation support for the entire reinforcing structure, thereby avoiding the offset of the suspended ceiling due to loose foundation. After the fixing column 3 is installed stably, the two suspended ceiling frame bodies 1 are moved to the top of the support plate 23 installed at the bottom of the fixing block 2, and the support plate 23 can provide a flat preliminary positioning surface for the suspended ceiling frame body 1, without the need for manual repeated horizontal calibration. Then, the suspended ceiling frame body 1 is pushed to make contact with the two push rods 10 on one side of the fixing block 2, the push rod 10 moves inward under the pushing force, and the tooth plate 18 at the end of the push rod 10 moves synchronously. Because the tooth plate 18 is engaged with the gear 19, the movement of the tooth plate 18 drives the gear 19 to rotate, which in turn drives the threaded rod 20 on one side of the gear 19 to rotate. The sliding block 5 on the surface of the threaded rod 20 slides along the square sliding groove 4 inside the fixing block 2, replacing the traditional screw fixation and avoiding the problem of rusting after long-term use. The cooperation of the square sliding groove 4 and the sliding block 5 can limit the rotation of the sliding block 5, ensure the translation precision of the moving plate 6, and avoid clamping offset. The end of the sliding block 5 extending to the outside of the fixing block 2 drives the moving plate 6, the fixed plate 7 at the bottom of the moving plate 6, and the clamping block 8 at the bottom of the fixed plate 7 to move synchronously. When the clamping block 8 moves into the fixed groove 11 inside the support plate 23 and contacts the G-shaped rod 24, the continuously moving clamping block 8 pushes the G-shaped rod 24 to move away from the baffle 25. After the G-shaped rod 24 is separated from the surface of the baffle 25, the spring three 27 inside the support plate 23 releases the elastic force, pushes the baffle 25 and the pull rod 12 connected to the baffle 25 to move towards the clamping block 8, and finally the pull rod 12 is inserted into the clamping groove 9 inside the clamping block 8. The elastic drive of the spring three 27 realizes the automatic clamping of the pull rod 12, without the need for manual alignment of the clamping groove 9, which reduces the operation difficulty. At the same time, the clamping structure can form double fixation, which is more stable than single screw fixation, and reduces the risk of loosening of the suspended ceiling after long-term use.

[0036] During this process, the limiting block one 28 and the limiting block two 29 inside the fixing block 2 limit the push rod 10 and the threaded rod 20 respectively, and the limiting block three 30 and the limiting block four 31 inside the support plate 23 limit the G-shaped rod 24 and the pull rod 12 respectively. Each limiting block can constrain the movement trajectory of the components to avoid transmission failure caused by component offset. Finally, the suspended ceiling plate is embedded into the U-shaped installation slot 15 inside the suspended ceiling frame body 1 and the bottom plate 16. The clamping design of the U-shaped installation slot 15 does not require the screw to penetrate the suspended ceiling plate, which avoids structural damage to the suspended ceiling plate due to drilling and realizes quick installation of the suspended ceiling plate. The slot body is tightly fitted with the edge of the suspended ceiling plate, which meets the clean room requirements of no exposed gaps and reduced dust accumulation.

[0037] When the ceiling needs to be repaired and the related parts are disassembled, the ceiling plate is first pulled out of the groove body along the opening direction of the U-shaped mounting groove 15. The open clamping structure of the U-shaped groove does not need to disassemble any fasteners, and the ceiling plate can be directly pulled out. The disassembly time of a single ceiling plate is greatly shortened, and the fixed state of the surrounding ceiling plate is not affected. Then the worker pulls the pull rod 12 on the support plate 23 outward, and the pull rod 12 drives the baffle 25 to move away from the clamping block 8. When the baffle 25 moves to one side of the G-shaped rod 24, the spring 26 in the support plate 23 releases the elastic force, pushes the G-shaped rod 24 to move upward and limits the baffle 25, and the automatic reset function of the spring 26 does not need manual fixing of the G-shaped rod 24, which simplifies the operation process, and the limiting structure can prevent the baffle 25 from accidentally resetting to ensure the safety of the subsequent disassembly process.

[0038] Then move the ceiling frame body 1 to weaken the extrusion force on the push rod 10, the spring 21 on both sides of the limiting plate 22 in the fixed block 2 releases the elastic force, pushes the tooth plate 18 to move away from the gear 19, the tooth plate 18 drives the gear 19 to rotate in the opposite direction, and then the threaded rod 20 rotates in the opposite direction, the sliding block 5 slides in the opposite direction along the sliding groove 4, drives the moving plate 6, the fixed plate 7 and the clamping block 8 to move upward, and the elastic reset of the spring 21 realizes the automatic reset of the transmission mechanism, without manual disassembly of the gear, threaded rod and other parts, which protects the transmission parts from damage during disassembly, prolongs the service life of the device, avoids the loss or misplacement of parts caused by manual disassembly, and provides convenience for subsequent reinstallation. Until the height of the clamping block 8 is higher than the top of the ceiling frame body 1, at this time the clamping block 8 no longer forms a vertical obstacle to the ceiling frame body 1, and the worker can easily remove the ceiling frame body 1 from the top of the support plate 23, avoiding structure collision caused by part interference during disassembly, and reducing the risk of damage to the ceiling frame body 1.

[0039] If further disassembly of the foundation parts of the reinforcing structure is required, the fixed bolt 14 on the mounting plate 13 can be unscrewed, and the fixed column 3 and the fixed block 2 can be removed from the mounting position. The detachable design of the bolt connection enables the foundation parts to be disassembled as needed, flexibly adapts to scenarios such as plant renovation and equipment update, improves the reusability of the device, and reduces resource waste.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.

10. A construction method for reinforcing the ceiling structure of a cleanroom, characterized in that: Includes the following steps: S1: The staff uses the fixed column (3), the mounting plate (13) and the fixing bolt (14) to fix the device in the designated position required for construction, so as to build a basic support structure for the subsequent fixing of the main body of the ceiling frame; S2: After the fixed column (3) is installed, the staff will move the two ceiling frame bodies (1) to the top of the support plate (23) to ensure that the ceiling frame bodies (1) are initially in a state of waiting to be fixed. S3: The staff pushes the ceiling frame body (1) so that the ceiling frame body (1) and the two push rods (10) that slide and cooperate with the fixed block (2) come into contact. As the ceiling frame body (1) continues to push, the push rods (10) move into the fixed block (2), which in turn drives the toothed plate (18) at one end of the push rod (10) to move synchronously. The movement of the toothed plate (18) will drive the gear (19) to rotate. The threaded rod (20) installed on one side of the gear (19) rotates synchronously with the gear (19). Under the rotation of the threaded rod (20), the square sliding block (5) slides down along the two square sliding grooves (4) opened inside the fixed block (2). The moving plate (6) installed at one end of the sliding block (5) to the outside of the fixed block (2) moves with the sliding block (5). The fixed plate (7) at the bottom of the moving plate (6) and the locking block (8) at the bottom of the fixed plate (7) also move synchronously. S4: When the locking block (8) moves into the two fixed slots (11) inside the support plate (23), the locking block (8) contacts the G-shaped rod (24) that slides at the bottom of the fixed slot (11). The continuously moving locking block (8) drives the G-shaped rod (24) to move downward. When the G-shaped rod (24) moves to the point of disengaging from the surface of the baffle (25), the limit on the baffle (25) is released. Under the elastic force of the spring three (27), the baffle (25) drives the pull rod (12) to move towards the locking block (8) until the pull rod (12) moves into the locking slot (9) inside the locking block (8), thus completing the fixing of the locking block (8) and thereby fixing the ceiling frame body (1). At this time, the ceiling panel can be inserted into the ceiling frame body (1) to complete the installation. S5: When it is necessary to remove the main body (1) of the ceiling frame, first remove the ceiling panel, and the staff pull the pull rod (12) outward. The pull rod (12) drives the baffle (25) at one end to move away from the block (8). When the baffle (25) moves to the side of the G-shaped rod (24), under the elastic force of the second spring (26), the G-shaped rod (24) moves upward, which limits the baffle (25) and prevents the baffle (25) from resetting. S6: The staff moves the main body of the ceiling frame (1) to reduce its squeezing force on the push rod (10); under the elastic restoring force of the spring (21), the toothed plate (18) moves away from the gear (19), causing the gear (19) to rotate in the opposite direction, and the threaded rod (20) rotates in the opposite direction synchronously with the gear (19); the sliding block (5) slides in the opposite direction along the sliding groove (4), causing the moving plate (6), the fixed plate (7), and the locking block (8) to move upward until the height of the locking block (8) is higher than the top of the main body of the ceiling frame (1); S7: After the card block (8) moves up to the top of the ceiling frame body (1), the staff will remove the ceiling frame body (1) from the top of the support plate (23) to complete the unfixing operation of the ceiling frame body (1).
