Description

Technical Field

[0001] This utility model relates to the field of cleanroom building materials technology, specifically to a prefabricated color steel plate for cleanrooms. Background Technology

[0002] In industries with extremely high requirements for production environments, such as electronics, pharmaceuticals, and food, cleanrooms are indispensable and crucial facilities. Cleanrooms need to possess excellent sealing, dustproofing, antistatic properties, and structural stability to ensure that the indoor environment meets stringent cleanliness standards.

[0003] Currently, cleanroom walls and ceilings are mostly constructed using color steel panels. Traditionally, cleanroom color steel panels are installed by splicing individual panels together using fixed connectors. However, this splicing method has several drawbacks. Firstly, the traditional connection structure is often fixed, making it impossible to flexibly adjust the angles between the panels. When the cleanroom has corners, irregular shapes, or requires layout adjustments based on actual usage needs, traditional color steel panels are difficult to adapt, requiring cutting and welding, which not only increases construction difficulty and cost but may also damage the structural integrity and sealing of the panels, affecting the overall performance of the cleanroom. Secondly, the stability and firmness of existing color steel panel connection structures after fixing need improvement. Loosening may occur during long-term use, leading to a decrease in the cleanroom's sealing, allowing external dust and impurities to easily enter and affect the cleanroom's cleanliness.

[0004] In addition, the materials and internal filling structure of traditional color steel plates also have certain shortcomings. Some color steel plates use materials with poor anti-static properties, which can easily generate static electricity in cleanrooms, an environment sensitive to static electricity, attracting dust and affecting product quality. Moreover, the thermal insulation, sound insulation, and structural strength of the internal filling materials are also difficult to meet the high standards required for cleanrooms.

[0005] Therefore, in order to address the above problems, it is of great practical significance to develop a prefabricated color steel plate for cleanrooms that can achieve arbitrary angle adjustment, has a firm and stable connection, and has good overall performance. Utility Model Content

[0006] This utility model aims to solve the problems of fixed connection structure of existing color steel plates for cleanrooms, inability to flexibly adjust the angle, poor connection stability, and difficulty in meeting the requirements of overall performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated color steel plate for cleanrooms, comprising a left color steel plate and a right color steel plate, with a connecting part between the left and right color steel plates. The left and right color steel plates have identical structures. The left color steel plate is composed of a pair of color steel plates connected by a foam filler. Both ends of the color steel plates are stamped with S-shaped structures, and the S-shaped structures on the two color steel plates form a T-shaped structure. The connecting part includes a support rod, on which a right support plate is fixed. A through hole is provided at the center of the support rod. An upper rotating seat is provided at the upper support rod via a bearing, and a lower rotating seat is provided at the lower support rod via a bearing. A left support plate is fixed on the upper and lower rotating seats. A threaded sleeve is fixed on the support rod at the center of the through hole. A lead screw is threaded onto the threaded sleeve. A handle is fixed to the top of the lead screw via a connecting rod passing through the upper rotating seat. A first push rod is fixed to the bottom of the lead screw. A second push rod is fixed to one end of the lower rotating seat, and the second push rod extends into the through hole and is on the same vertical axis as the first push rod. T-slots adapted to the T-shaped structure are provided on both the left and right support plates.

[0008] The color steel plate is made of galvanized steel plate and its surface is coated with an antistatic coating; the foam filler is high-density polyurethane foam and its interior is uniformly distributed with glass fiber reinforced mesh; the outer surface of the handle is covered with a rubber anti-slip sleeve, and the rubber anti-slip sleeve has uniformly distributed anti-slip textures; the inner wall of the T-slot is covered with a sealing strip, and the sealing strip is made of aging-resistant silicone rubber; the bearings between the upper and lower swivel seats and the support rod are deep groove ball bearings, and the bearings are filled with grease.

[0009] The left and right color steel panels are connected and their angles can be adjusted via a connecting part, as detailed below:

[0010] The T-shaped structure of the left color steel plate matches the T-shaped groove of the left support plate, and the T-shaped structure of the right color steel plate matches the T-shaped groove of the right support plate, so that the left and right color steel plates are respectively installed on the left and right support plates.

[0011] Since the left support plate is fixed on the upper and lower swivels, and the upper and lower swivels are connected to the support rod through deep groove ball bearings filled with grease, the upper and lower swivels can rotate flexibly around the support rod, thereby driving the left color steel plate to rotate around the support rod; at the same time, the right support plate is fixed on the support rod, and the right color steel plate remains relatively fixed with the right support plate. This achieves relative rotation between the left and right color steel plates, so that the angle between them can be adjusted arbitrarily according to actual needs.

[0012] Once the angle is adjusted to the appropriate position, it needs to be fixed. At this point, turn the handle, which in turn drives the lead screw to rotate via the connecting rod. Since the lead screw is threadedly connected to the threaded sleeve fixed on the support rod, the lead screw will move downwards along the threaded sleeve during rotation, and the push rod at the bottom of the lead screw will also move downwards accordingly.

[0013] Because the second push rod is fixed at one end of the lower rotating seat and extends into the through hole, and is on the same vertical axis as the first push rod, when the first push rod moves downward to a certain extent, it will come into contact with the second push rod and apply downward pressure to it, thereby pressing the lower rotating seat tightly against the support rod. The friction generated by the pressing will limit the lower rotating seat, preventing it from rotating around the support rod.

[0014] Since the left support plate is fixed on the lower rotating base, the left color steel plate is also fixed, while the right color steel plate is fixed relative to the support rod. Therefore, the angle between the left and right color steel plates is stabilized and fixed, preventing rotation during subsequent use and ensuring the stability of the cleanroom structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Achieve arbitrary angle adjustment: Through the bearing connection between the upper and lower swivel seats of the connecting part and the support rod, the left and right color steel plates can rotate around the support rod, thereby achieving arbitrary angle adjustment between them. This can adapt to the needs of various corners, irregular structures and different layouts in cleanrooms, greatly improving the flexibility of construction.

[0017] The connection is firm and stable: by turning the handle, the lead screw is rotated, which in turn moves the first push rod downward to tighten the second push rod. This effectively limits the lower rotating seat, thereby fixing the angle between the left and right color steel plates and preventing them from rotating during use, thus ensuring the firmness and stability of the connection.

[0018] Excellent overall performance: The color steel plate is made of galvanized steel sheet with an anti-static coating, providing excellent anti-static and corrosion resistance; the foam filler is high-density polyurethane foam with internal glass fiber reinforcement, improving the thermal insulation, sound insulation, and structural strength of the color steel plate; the sealing strip in the T-slot ensures the sealing of the connection points, and the aging-resistant silicone rubber material extends its service life; the deep groove ball bearing and internal grease ensure smooth and flexible rotation.

Example

[0028] like Figure 1-5 As shown;

[0029] A prefabricated color steel plate for cleanrooms.

[0030] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "Currently, cleanroom walls and ceilings are mostly constructed using color steel plates. Traditionally, the color steel plates used in cleanrooms are spliced ​​together using fixed connectors during installation. However, this splicing method has many drawbacks. On the one hand, the traditional connection structure is often fixed, making it impossible to flexibly adjust the angles between the color steel plates. When the cleanroom has corners, irregular structures, or requires layout adjustments based on actual usage needs, traditional color steel plates are difficult to adapt and can only be processed through cutting, welding, etc., which not only increases construction difficulty and cost but may also damage the structural integrity and sealing of the color steel plates, affecting the overall performance of the cleanroom. On the other hand, the stability and firmness of the existing color steel plate connection structure after fixing need improvement. Loosening may occur during long-term use, leading to a decrease in the cleanroom's sealing performance, allowing external dust and impurities to easily enter the room, affecting the cleanliness of the cleanroom."

[0031] Furthermore, traditional color steel panels also have certain shortcomings in terms of material and internal filling structure. Some color steel panels use materials with poor anti-static properties, which can easily generate static electricity in cleanrooms, an environment sensitive to static electricity, attracting dust and affecting product quality. Moreover, the insulation, sound insulation, and structural strength of the internal filling materials are also insufficient to meet the high standards required for cleanrooms. In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to address this technical problem, a prefabricated color steel panel for cleanrooms is provided.

[0032] like Figure 1-5 As shown in the figure;

[0033] This utility model provides a technical solution: a prefabricated color steel plate for cleanrooms, comprising a left color steel plate 1 and a right color steel plate 2, with a connecting part 3 between the left and right color steel plates 1 and 2. The left and right color steel plates 1 and 2 have identical structures. The left color steel plate 1 consists of a pair of color steel plates 11, which are made of galvanized steel and coated with an anti-static coating to effectively prevent static electricity generation, avoid dust adsorption, and improve the corrosion resistance of the color steel plate. The two color steel plates 11 are connected by a foam filler 12, which is high-density polyurethane foam with uniformly distributed glass fiber reinforcement mesh inside. The high-density polyurethane foam has good thermal insulation and sound insulation properties, while the glass fiber reinforcement mesh enhances the overall structural strength of the left color steel plate 1.

[0034] Both ends of the color steel plate 11 are stamped with S-shaped structures 13, and the S-shaped structures 13 on the two color steel plates 11 form a T-shaped structure 14. The connecting part 3 includes a support rod 31, on which a right support plate 32 is fixed. A through hole 33 is opened at the center of the support rod 31. An upper swivel seat 34 is set at the support rod 31 above the through hole 33 via a deep groove ball bearing, and a lower swivel seat 35 is set at the support rod 31 below the through hole 33 via a deep groove ball bearing. The deep groove ball bearing is filled with grease to ensure the smooth rotation of the upper swivel seat 34 and the lower swivel seat 35 around the support rod 31. Left support plate 36 is fixed on the upper rotating base 34 and the lower rotating base 35. Both the left support plate 36 and the right support plate 32 are provided with T-shaped grooves 39 that are compatible with the T-shaped structure 14. Sealing strips are pasted on the inner wall of the T-shaped grooves 39. The sealing strips are made of aging-resistant silicone rubber. When the left color steel plate 1 and the right color steel plate 2 are connected to the left support plate 36 and the right support plate 32 respectively, the sealing of the connection parts can be guaranteed to prevent dust and other objects from entering the clean room. At the same time, the silicone rubber material is aging-resistant, which extends the service life of the sealing strips.

[0035] A threaded sleeve 37 is fixed to the support rod 31 at the center of the through hole 33. A lead screw 38 is threaded onto the threaded sleeve 37. The top of the lead screw 38 passes through the upper rotary seat 34 via a connecting rod 381 and is fixed to a handle 382. The outer surface of the handle 382 is covered with a rubber anti-slip sleeve, and the rubber anti-slip sleeve has evenly distributed anti-slip patterns to facilitate the operator's application of force when turning the handle 382 and prevent slippage. A first push rod 383 is fixed to the bottom end of the lead screw 38, and a second push rod 351 is fixed to one end of the lower rotary seat 35. The second push rod 351 extends into the through hole 33 and is on the same vertical axis as the first push rod 383.

[0036] During installation and use, first insert the T-shaped structure 14 of the left color steel plate 1 into the T-shaped groove 39 of the left support plate 36, and insert the T-shaped structure 14 of the right color steel plate 2 into the T-shaped groove 39 of the right support plate 32, thus completing the initial connection between the left and right color steel plates 1 and the connecting part 3. According to the layout and structural requirements of the cleanroom, rotate the left color steel plate 1. The left color steel plate 1 drives the left support plate 36 to rotate, and the left support plate 36 drives the upper rotating seat 34 and the lower rotating seat 35 to rotate around the support rod 31, thereby adjusting the angle between the left and right color steel plates 1 and 2. After the angle is adjusted appropriately, turn the handle 382. The handle 382 drives the lead screw 38 to rotate inside the threaded sleeve 37 through the connecting rod 381. The lead screw 38 moves downward, driving the first push rod 383 to move downward. The first push rod 383 contacts the second push rod 351 and applies pressure to it, pressing the lower rotating seat 35 against the support rod 31, thereby limiting the lower rotating seat 35 and fixing the angle between the left color steel plate 1 and the right color steel plate 2, thus completing the installation.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
