Description

Technical Field

[0001] This invention relates to the field of composite wall panels, and in particular to a composite wall panel structure for prefabricated buildings. Background Technology

[0002] In the field of prefabricated buildings, composite wall panels are important building components. Their assembly efficiency, ease of operation and structural reliability directly affect the overall construction progress and performance. Therefore, optimizing the connection structure of composite wall panels has always been a research focus in this field.

[0003] The existing structural design of composite wall panels for prefabricated buildings has shortcomings in terms of ease of assembly and disassembly, storage, and reliability. Specifically: during assembly, multiple wall panels need to be fixed through complex operations or additional tools, making it difficult to quickly complete the insertion and locking; similarly, there is a lack of convenient means to release the snap-fit ​​during disassembly, making the operation time-consuming and laborious; the connecting parts between wall panels are mostly fixed designs, occupying a large space when storing or reassembling, making them inconvenient to store; the inner cavity of the snap-fit ​​mechanism is susceptible to external dust intrusion, which may cause the internal moving parts to jam, affecting normal operation; in addition, the return mechanism of the snap-fit ​​parts is imperfect, lacking an effective elastic auxiliary structure, which can easily lead to untimely or incomplete return, reducing the overall structural stability and reliability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a composite wall panel structure for prefabricated buildings. This addresses the issues of: the need for complex operations or additional tools to fix multiple wall panels during assembly, making quick insertion and locking difficult; the lack of convenient means to release the interlocking mechanism during disassembly, resulting in time-consuming and labor-intensive operations; the fixed design of connecting components between wall panels, which takes up significant space during storage or reassembly, making them inconvenient to store; the vulnerability of the interlocking mechanism's internal cavity to external dust, potentially causing jamming of internal moving parts and affecting normal operation; and the imperfect return mechanism of the interlocking components, lacking an effective elastic auxiliary structure, leading to untimely or incomplete return, thus reducing the overall structural stability and reliability.

[0005] To achieve the above objectives, this application provides the following technical solution: a composite wall panel structure for prefabricated buildings, comprising a composite wall panel body and a hollow assembly box body. The hollow assembly box body is opened on the outside of the composite wall panel body, and there are at least eight sets of hollow assembly box bodies. The inner cavity of the hollow assembly box body is slidably connected with a snap-fit ​​mechanism, and a drive push plate is inserted into the front of the hollow assembly box body. By setting at least eight sets of hollow assembly box bodies, assembly support points can be provided from multiple directions of the composite wall panel body, greatly improving the overall stability of the wall panel after assembly and avoiding loosening of the connection due to excessive force on a single point.

[0006] The drive push plate can directly act on the locking mechanism, enabling rapid control of the locking state without the need for complex tools, thus simplifying the assembly process. The locking mechanism includes a sliding assembly block slidably connected to the hollow assembly box. An insert block is externally connected to the sliding assembly block, and a locking tongue is rotatably connected to the inner cavity of the sliding assembly block. A control lever is externally connected to the locking tongue, and a first spring connects the control lever to the sliding assembly block. A push block is inserted externally into the sliding assembly block, and a pressure rod is externally connected to the push block. A second spring connects the push block to the sliding assembly block, and a baffle is slidably connected to the inner cavity of the sliding assembly block. A third spring connects the baffle to the sliding assembly block.

[0007] The sliding assembly block slides within the hollow assembly box, causing the insert block to extend or retract, enabling docking or separation with adjacent wall panels. The locking tongue remains locked under the action of the first spring, ensuring the stability of the connection, while the operating lever can manually unlock it for easy disassembly and adjustment. The push block, controlled by the pressure rod and in conjunction with the restoring force of the second spring, can precisely control the state of the locking tongue. The baffle, under the action of the third spring, can limit the locking tongue, further ensuring the reliability of the lock.

[0008] Preferably, the inner cavity of the sliding assembly block is provided with an assembly groove, and the assembly groove is slidably connected to the baffle.

[0009] The mounting groove provides a stable sliding trajectory for the baffle, ensuring that the baffle can accurately limit the locking tongue under the action of the second spring, avoiding baffle deviation that could lead to locking failure. At the same time, it reduces the frictional resistance when the baffle slides, extending the service life of the components.

[0010] Preferably, the inner cavity of the sliding assembly block is provided with a square groove, and the square groove is slidably connected to the outside of the control lever.

[0011] The square groove limits the range of motion of the control lever to prevent excessive deviation when the control lever drives the locking tongue to rotate, ensuring that the elastic force of the first spring can be stably transmitted to the control lever, so that the locking tongue always maintains the correct locking position when not in operation.

[0012] Preferably, a closed cover is provided at the junction of the drive push plate and the composite wall panel, and a protective cover is provided between the pressure rod and the sliding assembly block.

[0013] The sealing cover effectively prevents dust, moisture and other impurities from entering the gap between the drive push plate and the composite wall panel, preventing parts from rusting or getting stuck; the protective cover protects the connection between the pressure rod and the sliding assembly block, avoiding external impact that could cause deformation of the pressure rod or damage to the second spring, thus improving the durability of the structure.

[0014] Preferably, the outer surface of the composite wall panel is uniformly provided with grooves, the inner cavity of the grooves is connected to the assembly hollow box, and a limiting member is connected between the grooves and the assembly hollow box.

[0015] The evenly distributed grooves provide an installation reference for the assembly of hollow boxes, ensuring the positional accuracy of each group of assembled hollow boxes. Through the fixing of the limiting parts, the assembled hollow boxes can be firmly connected to the composite wall panel, preventing the assembled hollow boxes from loosening or falling off during assembly or use, thus ensuring the stability of the overall structure.

[0016] Preferably, the composite wall panel is made of lightweight concrete and glass fiber reinforced composite material, and the thickness of the composite wall panel is 8 to 15 cm. The outside of the insert is provided with anti-slip texture, and the end of the insert has a wedge-shaped structure.

[0017] The combination of lightweight concrete and glass fiber reinforced composite materials ensures the structural strength required for the composite wall panel to have a thickness of 8-15 cm, while significantly reducing the self-weight of the wall panel, making it easier to transport and hoist. The anti-slip texture on the outside of the insert increases the friction with the mating parts, preventing slippage after connection, while the wedge-shaped end makes it easier for the insert to be inserted into the mating hole, reducing assembly difficulty and improving assembly efficiency.

[0018] Preferably, the first spring, the second spring, and the third spring are all made of high-strength spring steel, and the elastic coefficient of the first spring is greater than that of the second spring. A guide block is provided on the outside of the push block, and a guide groove adapted to the guide block is opened in the inner cavity of the sliding assembly block.

[0019] The springs made of high-strength spring steel can maintain good elasticity after long-term stress and frequent expansion and contraction, thus extending their service life; the elastic coefficient of the first spring is greater than that of the second spring, which can ensure that the locking force of the bolt is greater than the pushing force of the push block, avoiding locking failure due to misoperation; the cooperation between the guide block and the guide groove ensures that the push block will not deviate when sliding, thus ensuring precise driving of the bolt.

[0020] Preferably, the end of the pressure rod is provided with a rubber handle, and the outer surface of the rubber handle is provided with a textured surface. The outer surface of the baffle is connected with a wear-resistant pad, and the wear-resistant pad is made of polytetrafluoroethylene material.

[0021] The textured surface of the rubber grip increases friction between the hand and the lever, preventing slippage during operation. The rubber material also provides some elasticity, enhancing operational comfort. The PTFE wear-resistant pad has an extremely low coefficient of friction and excellent wear resistance, reducing wear when the baffle contacts the locking tongue, extending the baffle's lifespan, and ensuring long-term stability of the limiting effect.

[0022] Preferably, the inner cavity of the assembled hollow box is provided with a lubrication layer, and the lubrication layer is a graphite lubrication coating. The outer surface of the sliding assembly block is provided with scale lines to indicate the sliding distance of the sliding assembly block.

[0023] The graphite lubricating coating, as a lubricating layer, can effectively reduce the sliding friction between the sliding assembly block and the assembly hollow box, making the sliding process smoother and reducing component wear. The scale lines on the outside of the sliding assembly block can intuitively display its sliding distance, making it easy for operators to accurately control the extension length of the insert block, ensuring the synchronization of multiple sets of snap-fit ​​mechanisms, and improving assembly quality.

[0024] In summary, this application provides a composite wall panel structure for prefabricated buildings, which has the following beneficial effects: This composite wall panel structure for prefabricated buildings, through the cooperation of composite wall panel bodies, assembly hollow boxes, drive push plates, and snap-fit ​​mechanisms, allows for convenient assembly of multiple composite wall panels. During assembly, an insert block from one composite wall panel is inserted into the inner cavity of a sliding assembly block on another composite wall panel. The interaction and return of the locking tongues quickly secure the two sets of sliding assembly blocks, facilitating the assembly of multiple composite wall panels. For disassembly, pressing down the lever drives the push block, which in turn rotates the control lever, quickly releasing the snap-fit ​​between the two sets of composite wall panels. The operation is simple and efficient. Simultaneously, pulling the drive push plate retracts the assembly hollow box into its interior, facilitating the storage or reassembly of multiple composite wall panels. The cooperation between the baffle and the third spring in the snap-fit ​​mechanism effectively prevents external dust from entering the inner cavity of the sliding assembly block, ensuring the normal operation of all components of the snap-fit ​​mechanism. The first and second springs assist the locking tongue, push block, and other components in returning to their original positions, improving structural stability and reliability. Overall, this enhances the assembly efficiency and ease of use of the composite wall panel structure in prefabricated buildings. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A composite wall panel structure for prefabricated buildings includes a composite wall panel body 1 and a prefabricated hollow box body 2. The prefabricated hollow box body 2 is opened on the outside of the composite wall panel body 1, and there are at least eight sets of prefabricated hollow box bodies 2. The inner cavity of the prefabricated hollow box body 2 is slidably connected with a snap-fit ​​mechanism 4, and a drive push plate 3 is inserted into the front of the prefabricated hollow box body 2. Please refer to Figure 3 By setting at least eight sets of hollow assembly boxes 2, assembly support points can be provided from multiple directions of the composite wall panel 1, greatly improving the overall stability of the wall panel after assembly and avoiding loosening of the connection due to excessive force on a single point. The drive push plate 3 can directly act on the snap-fit ​​mechanism 4 to achieve rapid control of the snap-fit ​​state without the need for complex tools, thus simplifying the assembly operation process. The locking mechanism 4 includes a sliding assembly block 41, which is slidably connected to the assembly hollow box 2. An insert block 42 is connected to the outside of the sliding assembly block 41. A locking tongue 43 is rotatably connected to the inner cavity of the sliding assembly block 41. An operating lever 45 is connected to the outside of the locking tongue 43. A first spring 46 is connected between the operating lever 45 and the sliding assembly block 41. A push block 48 is inserted into the outside of the sliding assembly block 41. A pressure rod 410 is connected to the outside of the push block 48. A second spring 49 is connected between the push block 48 and the sliding assembly block 41. A baffle 411 is slidably connected to the inner cavity of the sliding assembly block 41. A third spring 412 is connected between the baffle 411 and the sliding assembly block 41.

[0029] Please refer to Figure 4 and Figure 5The sliding assembly block 41 slides within the hollow assembly box 2, which can cause the insert block 42 to extend or retract, enabling docking or separation with adjacent wall panels; the locking tongue 43 can remain locked under the action of the first spring 46, ensuring the stability of the connection, while the operating lever 45 can manually unlock it for easy disassembly and adjustment; the push block 48, through the operation of the pressure rod 410 and in conjunction with the restoring force of the second spring 49, can precisely control the state of the locking tongue 43; the baffle 411, under the action of the third spring 412, can limit the locking tongue 43, further ensuring the reliability of the lock.

[0030] The inner cavity of the sliding assembly block 41 is provided with an assembly groove 44, which is slidably connected to the baffle 411.

[0031] The mounting groove 44 provides a stable sliding trajectory for the baffle 411, ensuring that the baffle 411 can accurately limit the locking tongue 43 under the action of the second spring 49, avoiding the baffle 411 from deviating and causing locking failure, while reducing the frictional resistance when the baffle 411 slides and extending the service life of the component.

[0032] The inner cavity of the sliding assembly block 41 is provided with a square groove 47, which is slidably connected to the outside of the control lever 45.

[0033] The square groove 47 limits the range of motion of the control lever 45 to prevent excessive deviation when the control lever 45 drives the locking tongue 43 to rotate, ensuring that the elastic force of the first spring 46 can be stably transmitted to the control lever 45, so that the locking tongue 43 always maintains the correct locking position when not in operation.

[0034] A closed cover is provided at the junction of the drive push plate 3 and the composite wall panel 1, and a protective cover is provided between the pressure rod 410 and the sliding assembly block 41.

[0035] The sealing cover can effectively block dust, moisture and other impurities from entering the gap between the drive push plate 3 and the composite wall panel 1, preventing the components from rusting or getting stuck; the protective cover protects the connection between the pressure rod 410 and the sliding assembly block 41, avoiding external impact that could cause the pressure rod 410 to deform or the second spring 49 to be damaged, thus improving the durability of the structure.

[0036] The composite wall panel 1 has uniformly distributed grooves on its exterior. The inner cavity of the grooves connects to the assembled hollow box 2, and a limiting member 21 connects the grooves and the assembled hollow box 2. The uniformly distributed grooves provide an installation reference for the assembled hollow box 2, ensuring the positional accuracy of each group of assembled hollow box 2. By fixing it with the limiting member 21, the assembled hollow box 2 can be firmly connected to the composite wall panel 1, preventing the assembled hollow box 2 from loosening or falling off during assembly or use, thus ensuring the stability of the overall structure.

[0037] The composite wall panel 1 is made of lightweight concrete and glass fiber reinforced composite material, and the thickness of the composite wall panel 1 is 8 to 15 cm. The outside of the insert 42 is provided with anti-slip texture, and the end of the insert 42 is wedge-shaped.

[0038] The combination of lightweight concrete and glass fiber reinforced composite material ensures the structural strength required for the composite wall panel 1 to have a thickness of 8-15 cm, while significantly reducing the self-weight of the wall panel, making it easier to transport and hoist. The anti-slip texture on the outside of the insert 42 increases the friction with the mating parts, preventing slippage after connection, while the wedge-shaped end makes it easier for the insert 42 to be inserted into the mating hole, reducing assembly difficulty and improving assembly efficiency.

[0039] The first spring 46, the second spring 49, and the third spring 412 are all made of high-strength spring steel, and the elastic coefficient of the first spring 46 is greater than that of the second spring 49. A guide block is provided on the outside of the push block 48, and a guide groove adapted to the guide block is opened in the inner cavity of the sliding assembly block 41. The springs made of high-strength spring steel can maintain good elastic performance after long-term stress and frequent expansion and contraction, thus extending their service life. The elastic coefficient of the first spring 46 is greater than that of the second spring 49, which can ensure that the locking force of the locking tongue 43 is greater than the pushing force of the push block 48, avoiding locking failure due to misoperation. The cooperation between the guide block and the guide groove ensures that the push block 48 will not deviate when sliding, thus ensuring precise driving of the locking tongue 43.

[0040] The end of the pressure rod 410 is provided with a rubber handle, and the outer surface of the rubber handle is provided with a textured surface. The outer surface of the baffle 411 is connected with a wear-resistant pad, and the wear-resistant pad is made of polytetrafluoroethylene material.

[0041] The textured surface of the rubber grip increases the friction between the hand and the lever 410, making it less prone to slipping during operation. The rubber material also has a certain degree of elasticity, improving the comfort of operation. The PTFE wear-resistant pad has an extremely low coefficient of friction and excellent wear resistance, which can reduce the wear when the baffle 411 contacts the locking tongue 43, extend the service life of the baffle 411, and ensure the long-term stability of the limiting effect.

[0042] The inner cavity of the hollow box 2 is equipped with a lubrication layer, which is made of graphite lubricating coating. The outer surface of the sliding assembly block 41 is marked with scale lines to indicate the sliding distance of the sliding assembly block 41. As a lubricating layer, the graphite lubricating coating can effectively reduce the sliding friction between the sliding assembly block 41 and the hollow box 2, making the sliding process smoother and reducing component wear. The scale lines on the outer surface of the sliding assembly block 41 can intuitively display its sliding distance, making it easy for operators to accurately control the extension length of the insert block 42, ensuring the synchronization of multiple sets of snap-fit ​​mechanisms 4, and improving assembly quality.

[0043] Insert the insert 42 from one composite wall panel 1 into the inner cavity of the sliding assembly block 41 from another composite wall panel 1. At this time, the two locking tongues 43 will contact each other. When the insert 42 is fully inserted into the inner cavity of the sliding assembly block 41, the locking tongue 43 returns to its original position, thereby fixing the two sets of sliding assembly blocks 41 together. When it is necessary to engage the two sets of composite wall panels 1, press down the pressure rod 410, drive the push block 48 to drive the control lever 45 to drive the locking tongue 43 to rotate, and then engage the two sets of composite wall panels 1. At the same time, pull up the drive push plate 3 to retract the assembly hollow box 2 into the interior of the assembly hollow box 2, which facilitates the storage or assembly of multiple sets of composite wall panels 1. Meanwhile, the baffle 411 prevents external dust from entering the inner cavity of the sliding assembly block 41.

[0044] Align the insert 42 in one composite wall panel 1 with the inner cavity of the sliding assembly block 41 in another composite wall panel 1, and then insert the insert 42 into the inner cavity. During the insertion of the insert 42, since the end of the insert 42 is wedge-shaped and the sliding assembly block 41 is slidably connected to the assembly hollow box 2, the inner cavity of the assembly hollow box 2 is slidably connected to the locking mechanism 4. The locking mechanism 4 includes components such as the sliding assembly block 41, the insert 42, and the locking tongue 43. At this time, the two locking tongues 43 will contact each other due to the insertion of the insert 42. As the insert 42 is continuously inserted.

[0045] Through the cooperation of the composite wall panel 1, the assembly hollow box 2, the drive push plate 3, and the snap-fit ​​mechanism 4, during assembly, the insert block 42 in one composite wall panel 1 is inserted into the inner cavity of the sliding assembly block 41 in another composite wall panel 1. Utilizing the interaction and return of the locking tongue 43, the two sets of sliding assembly blocks 41 can be quickly fixed together, thus conveniently completing the assembly of multiple sets of composite wall panels 1. When disassembly is required, pressing down the pressure rod 410 drives the push block 48 to move the operating lever 45, causing the locking tongue 43 to rotate, quickly releasing the snap-fit ​​state of the two sets of composite wall panels 1. The operation is simple. High efficiency; at the same time, pulling the drive push plate 3 can retract the assembly hollow box 2 into its own interior, which is convenient for storing or reassembling multiple sets of composite wall panels 1; the cooperation between the baffle 411 and the third spring 412 in the snap-fit ​​mechanism 4 can effectively prevent external dust from entering the inner cavity of the sliding assembly block 41, ensuring the normal operation of each component of the snap-fit ​​mechanism 4; the setting of the first spring 46 and the second spring 49 can assist the locking tongue 43, push block 48 and other components to return to their positions, improve the stability and reliability of the structure, and improve the overall assembly efficiency and ease of use of the composite wall panel structure in prefabricated buildings.

[0046] The locking tongue 43 rotates, and an operating lever 45 is externally connected to the locking tongue 43. A first spring 46, made of high-strength spring steel, connects the operating lever 45 to the sliding assembly block 41. The first spring 46 is compressed. When the insert block 42 is fully inserted into the inner cavity of the sliding assembly block 41, the locking tongue 43 returns to its original position under the elastic force of the first spring 46, thereby fixing the two sets of sliding assembly blocks 41 together and achieving the assembly connection of the two composite wall panels 1. Simultaneously, the insert block 42 has anti-slip textures on its exterior, enhancing the stability of the connection. Furthermore, a baffle 411 is slidably connected to the inner cavity of the sliding assembly block 41, and a third spring 412 is connected between the baffle 411 and the sliding assembly block 41. The third spring 412 is made of high-strength spring steel, and a wear-resistant pad is connected to the outside of the baffle 411. The wear-resistant pad is made of polytetrafluoroethylene material. The baffle 411 can prevent external dust and other debris from entering the inner cavity of the sliding assembly block 41, ensuring the normal operation of the internal components. An assembly groove 44 is opened in the inner cavity of the sliding assembly block 41, and the assembly groove 44 is slidably connected to the baffle 411, providing a track for the sliding of the baffle 411.

[0047] When it is necessary to release the two sets of composite wall panels 1 from their snap-fit ​​state, since a push block 48 is inserted into the outside of the sliding assembly block 41, and a pressure rod 410 is connected to the outside of the push block 48, and a rubber grip is provided at the end of the pressure rod 410, the rubber grip is provided with concave and convex textures for easy gripping by the operator, when the pressure rod 410 is pressed down, the push block 48 will move downward accordingly. A second spring 49 is connected between the push block 48 and the sliding assembly block 41. The second spring 49 is made of high-strength spring steel, and the elastic coefficient of the first spring 46 is greater than that of the second spring 49. A guide block is provided on the outside of the push block 48, and a guide groove adapted to the guide block is opened in the inner cavity of the sliding assembly block 41. The cooperation between the guide block and the guide groove ensures the stability of the movement of the push block 48. The movement of the push block 48 will drive the control lever 45 to move. A square groove 47 is opened in the inner cavity of the sliding assembly block 41. The square groove 47 is slidably connected to the outside of the control lever 45, providing space for the movement of the control lever 45.

[0048] Moving the lever 45 will drive the locking tongue 43 to rotate, causing the locking tongue 43 to release the fixation of the two sets of sliding assembly blocks 41, thereby releasing the snap-fit ​​state of the two sets of composite wall panels 1; at the same time, a drive push plate 3 is inserted into the front of the assembly hollow box 2, and a closed cover is provided at the junction of the drive push plate 3 and the composite wall panel 1. A protective cover is provided between the pressure rod 410 and the sliding assembly block 41. Pulling the drive push plate 3 upward, since the inner cavity of the assembly hollow box 2 is provided with a lubrication layer, the lubrication layer adopts a graphite lubrication coating, and the sliding assembly block 41 is slidably connected to the assembly hollow box 2.

[0049] The sliding assembly block 41 has scale lines on its exterior to indicate the sliding distance of the sliding assembly block 41. Therefore, the assembly hollow box 2 will retract into the interior of the assembly hollow box 2, which facilitates the storage or reassembly of multiple sets of composite wall panels 1. In addition, the exterior of the composite wall panel 1 is uniformly provided with grooves. The inner cavity of the grooves is connected to the assembly hollow box 2. A limit member 21 is connected between the grooves and the assembly hollow box 2 to ensure the stability of the connection between the assembly hollow box 2 and the composite wall panel 1. The composite wall panel 1 is made of lightweight concrete and glass fiber reinforced composite material, which ensures the strength of the wall panel and reduces its weight, making it easy to assemble and transport.
