Description

Technical Field

[0001] This invention belongs to the field of construction structure technology, specifically a prefabricated construction structure and construction method for large public venues. Background Technology

[0002] In the construction of large public venues (such as stadiums, convention centers, transportation hubs, theaters, etc.), prefabricated wall panels are increasingly replacing traditional wet-work wall panels and are being widely used due to their significant advantages such as convenient construction, high degree of industrialization, short construction period, and less on-site pollution.

[0003] For example, a magnetic keel wall system based on modular walls, disclosed in CN119843839A, includes a prefabricated wall with several anchors; it also includes an integral keel, comprising vertical keels and connecting screws, the connecting screws passing through the vertical keels and threadedly connected to the anchors; and it further includes a support assembly, comprising a skirting board base fixed to the bottom side face of the vertical keel, and a skirting board plate fixed to the skirting board base. This invention solves the problems of putty layer cracking and uneven splicing of decorative panels existing in current decoration technologies.

[0004] While the above solutions can address issues such as putty layer cracking and uneven splicing of decorative panels in existing decoration techniques, the existing prefabricated wall panels have a flat surface without any disassembly support points after installation. When it is necessary to disassemble, replace, or adjust the position of the wall panels, workers have no leverage points to use, making disassembly difficult and requiring the use of other tools, resulting in extremely low disassembly efficiency. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a prefabricated construction structure and construction method for large public venues.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated construction structure for a large public venue, including interior walls, and further comprising: The steel leveling keel frame is installed on the vertical surface of the building's interior walls; Magnetic prefabricated wall panels are installed on the vertical surface of the steel leveling keel frame away from the interior wall of the building. The magnetic prefabricated wall panel is provided with a magnetic suction component unit for magnetic docking with the steel leveling keel frame at one end. The magnetic prefabricated wall panel is provided with symmetrical vertical slots on both sides. A rotating disassembly unit for quick disassembly of the magnetic prefabricated wall panel is provided in the vertical slots. The rotating and easily disassembled unit includes a protruding vertical block fixedly connected to the vertical surface of the side vertical slot. A vertical shaft is fixedly connected to the end of the protruding vertical block away from the building's interior wall. A pair of self-rebound hinges are assembled at the outer end of the vertical shaft. A self-rebound torsion spring is assembled between the self-rebound hinges and the vertical shaft. A rotatable plate is fixedly connected to the end of the pair of self-rebound hinges away from the protruding vertical block. The side vertical slot has an inclined groove surface near the contact surface of the rotatable strip. The inclined groove surface is adapted to the rotation trajectory of the rotatable strip to provide sufficient guiding space for the rotation of the rotatable strip and avoid jamming during rotation.

[0007] Preferably, a plurality of anti-slip protrusions are fixedly connected to one end of the rotatable strip near the vertical axis strip. The anti-slip protrusions are evenly spaced to improve the grip strength when the human hand holds the rotatable strip.

[0008] Preferably, a self-returning torsion spring is assembled between the self-returning hinge and the vertical shaft strip. The self-returning torsion spring is used to drive the self-returning hinge and the rotatable plate strip to automatically reset, ensuring that the rotating and detachable unit is in a hidden state during normal times.

[0009] Preferably, a limiting component unit is provided between the rotary easy-to-disassemble unit and the side vertical slot. The limiting component unit includes a locking vertical shaft fixedly connected to one side of the rotary easy-to-disassemble unit. A locking vertical slot is provided on one side of the side vertical slot, and a metal inner layer is fixedly connected to the inner wall of the locking vertical slot.

[0010] Preferably, the outer wall of the locking vertical shaft is fixedly connected with a magnetic outer layer, and the locking vertical shaft is locked into the locking vertical groove when the rotatable strip is rotated to the limit position, and at this time the locking vertical shaft and the magnetic outer layer are magnetically connected.

[0011] Preferably, the magnetic suction assembly unit includes a double-sided magnetic suction plate, with an adhesive outer layer symmetrically fixedly connected to both sides of the double-sided magnetic suction plate, and a weak magnetic inner plate fixedly connected to one side of the middle of the double-sided magnetic suction plate.

[0012] Preferably, a strong magnetic inner plate is fixedly connected to the other side of the middle part of the double-sided magnetic plate, and the weak magnetic inner plate and the strong magnetic inner plate can be glued to the back of the magnetic assembled wall panel by pasting the outer layer according to the actual situation.

[0013] Preferably, a joint sealant is provided between two adjacent magnetic prefabricated wall panels, and the joint sealant is made of a flexible and wear-resistant material.

[0014] Preferably, the thickness of the grout sealant is adapted to the gap width between two adjacent magnetic prefabricated wall panels.

[0015] This application also proposes a prefabricated construction method for large public venues, the construction method of which is as follows: S1: Fix the steel leveling keel frame to the vertical surface of the building's interior wall to ensure that the steel leveling keel frame is installed flat; S2: According to the installation requirements, the weak magnetic inner plate and the strong magnetic inner plate are glued to the back of the magnetic prefabricated wall panel by pasting the outer layer to complete the installation of the magnetic component unit. S3: The magnetic prefabricated wall panel is magnetically connected to the steel leveling keel frame through the magnetic suction component unit to complete the assembly of a single magnetic prefabricated wall panel. S4: Embed the joint sealant between two adjacent magnetic prefabricated wall panels to complete the joint filling; S5: During disassembly, rotate the rotatable strip to its limit position. After being limited by the limiting component unit, pull the rotatable strip to separate the magnetic prefabricated wall panel from the steel leveling keel frame, thus completing the disassembly.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By incorporating a rotating disassembly unit, a limiting component unit, and an inclined groove, the rotatable strip is smoothly guided by the inclined groove. Anti-slip ridges prevent slippage during gripping, and the magnetic connection of the limiting component unit provides stable positioning, facilitating disassembly by staff. After disassembly, a self-rebound torsion spring automatically resets and hides the rotatable strip. This design improves disassembly convenience and safety, prevents accidental contact by unauthorized personnel, protects the wall panel structure, enables reuse, and reduces the venue's future maintenance costs.

[0017] By using a structure with magnetic component units, the steel leveling keel frame is fixed to the interior wall of the building. Then, the weak magnetic inner plate, strong magnetic inner plate and magnetic prefabricated wall panel are bonded together by the outer layer. The magnetic component units enable the wall panel and the keel frame to be quickly connected. Finally, the gaps are filled by embedding the grout clips. This method eliminates the need for wet work such as bolts and welding, greatly improving assembly efficiency and ensuring assembly accuracy. It can also meet the needs of different areas of the venue through the flexible adaptation of weak and strong magnets. At the same time, it achieves dust and moisture protection and wall aesthetics, effectively solving the problems of cumbersome assembly, poor adaptability and insufficient aesthetics of existing prefabricated wall panels.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] like Figures 1 to 10 As shown, the present invention provides a prefabricated construction structure for a large public venue, including an interior wall 1, and further including: a steel leveling keel frame 2, which is set on the vertical surface of the interior wall 1; and a magnetic prefabricated wall panel 3, which is installed on the vertical surface of the steel leveling keel frame 2 away from the interior wall 1. The magnetic prefabricated wall panel 3 has a magnetic attraction component unit 7 for magnetically engaging with the steel leveling keel frame 2 at one end near the steel leveling keel frame 2. The magnetic prefabricated wall panel 3 has symmetrically opened side vertical slots 4 on both sides, and a rotating easy-to-disassemble unit 5 for quickly disassembling the magnetic prefabricated wall panel 3 is provided in the side vertical slots 4.

[0022] The above solution is adopted: the side vertical grooves 4 are opened on both sides of the magnetic prefabricated wall panel 3. The depth and width of the grooves are adapted to the structural dimensions of the rotating and easy-to-disassemble unit 5. This not only fully accommodates the rotating and easy-to-disassemble unit 5, ensuring that it is hidden in a hidden state and does not affect the aesthetics of the wall, but also provides sufficient installation and movement space for the rotation and force application of the rotating and easy-to-disassemble unit 5, avoiding component interference problems caused by unreasonable groove dimensions.

[0023] like Figures 3 to 8 As shown, the rotatable disassembly unit 5 includes a protruding vertical block 50 fixedly connected to the vertical surface of the side vertical slot 4. A vertical shaft 51 is fixedly connected to the end of the protruding vertical block 50 away from the building's interior wall 1. A pair of self-returning hinges 52 are fitted to the outer end of the vertical shaft 51. A self-returning torsion spring is fitted between the self-returning hinges 52 and the vertical shaft 51. A rotatable plate 53 is fixedly connected to the end of the pair of self-returning hinges 52 away from the protruding vertical block 50. An inclined groove 9 is formed on the contact surface of the side vertical slot 4 near the rotatable plate 53. The inclined groove 9 and the rotatable plate 53... The rotation trajectory of the slat 53 is adapted to provide sufficient guiding space for the rotation of the rotatable slat 53 and avoid jamming during rotation. Multiple anti-slip protrusions 54 are fixedly connected to one end of the rotatable slat 53 near the vertical shaft 51. The anti-slip protrusions 54 are evenly spaced to improve the grip force when the hand holds the rotatable slat 53. A self-returning torsion spring is installed between the self-returning hinge 52 and the vertical shaft 51. The self-returning torsion spring is used to drive the self-returning hinge 52 and the rotatable slat 53 to automatically reset, ensuring that the rotatable detachable unit 5 is in a hidden state during normal use.

[0024] The above solution is adopted: the rotating easy-to-disassemble unit 5 is embedded in the side vertical slot 4. Its core feature is that it can rotate and reset, providing a clear fulcrum for workers to disassemble the wall panel. This solves the technical problem that existing prefabricated wall panels have no disassembly fulcrum after installation and require the use of tools to pry them open, greatly improving the convenience of wall panel disassembly. The self-returning hinge 52 is a stainless steel self-returning hinge.

[0025] like Figures 3 to 9 As shown, a limiting component unit 6 is provided between the rotating easy-to-disassemble unit 5 and the side vertical slot 4. The limiting component unit 6 includes a locking vertical shaft 61 fixedly connected to one side of the rotating easy-to-disassemble unit 5. A locking vertical groove 63 is provided on one side of the side vertical slot 4. A metal inner layer 60 is fixedly connected to the inner wall of the locking vertical groove 63. A magnetic outer layer 62 is fixedly connected to the outer wall of the locking vertical shaft 61. When the rotatable strip 53 rotates to the limit position, the locking vertical shaft 61 is locked into the locking vertical groove 63, and at this time, the locking vertical shaft 61 and the magnetic outer layer 62 are magnetically connected.

[0026] The above solution is adopted: The core feature of the limiting component unit 6 is that it moves synchronously with the rotating easy-to-disassemble unit 5 to achieve temporary limiting after the rotatable strip 53 is rotated to the limit position. This solves the cumbersome operation that workers need to fix the rotatable strip 53 with one hand and pull it with the other hand when disassembling the wall panel, thus improving the efficiency and convenience of disassembly. The outer diameter of the locking vertical shaft 61 is precisely matched with the inner diameter of the locking vertical groove 63, ensuring that the locking vertical shaft 61 can be smoothly inserted into the locking vertical groove 63.

[0027] like Figures 3 to 10 As shown, the magnetic component unit 7 includes a double-sided magnetic plate 70. An adhesive outer layer 73 is symmetrically fixedly connected to both sides of the double-sided magnetic plate 70. A weak magnetic inner plate 71 is fixedly connected to one side of the middle of the double-sided magnetic plate 70, and a strong magnetic inner plate 72 is fixedly connected to the other side of the middle of the double-sided magnetic plate 70. The weak magnetic inner plate 71 and the strong magnetic inner plate 72 can be adhered to the back of the magnetic prefabricated wall panel 3 by the adhesive outer layer 73 according to the actual situation.

[0028] The core feature of the magnetic component unit 7 is that it can adapt to the force requirements of different areas according to the usage needs of different areas in large public venues. The weak magnetic inner plate 71 is suitable for areas in large public venues with less force and no need for high-strength fixation, such as office areas and rest areas, which facilitates the subsequent disassembly and adjustment of the wall panels. The strong magnetic inner plate 72 is suitable for areas with greater force and need for firm fixation, such as audience areas and competition areas, which can resist external forces such as crowd collisions and equipment vibrations, ensuring that the wall panels do not loosen or shift after installation.

[0029] like Figure 5 As shown, a joint sealant 8 is provided between two adjacent magnetic prefabricated wall panels 3. The joint sealant 8 is made of flexible and wear-resistant material, and the thickness of the joint sealant 8 is adapted to the gap width between the two adjacent magnetic prefabricated wall panels 3.

[0030] Using the above solution: The core features of the Tile Grout Clip 8 are flexibility, wear resistance, and size fit, and it is made of silicone material.

[0031] This application also proposes a prefabricated construction method for large public venues, the construction method of which is as follows: S1: Fix the steel leveling keel frame 2 to the vertical surface of the building's interior wall 1 to ensure that the steel leveling keel frame 2 is installed flat. S2: According to the installation requirements, the weak magnetic inner plate 71 and the strong magnetic inner plate 72 are glued to the back of the magnetic prefabricated wall panel 3 by pasting the outer layer 73, thus completing the installation of the magnetic suction component unit 7. S3: The magnetic prefabricated wall panel 3 is magnetically connected to the steel leveling keel frame 2 through the magnetic attraction component unit 7 to complete the assembly of a single magnetic prefabricated wall panel 3. S4: Embed the joint sealant 8 between two adjacent magnetic prefabricated wall panels 3 to complete the joint filling; S5: During disassembly, rotate the rotatable strip 53 to its limit position. After being limited by the limiting component unit 6, apply force to pull the rotatable strip 53 to separate the magnetic assembled wall panel 3 from the steel leveling keel frame 2, thus completing the disassembly.

[0032] Working principle and usage process of this invention: First, assembly preparation is carried out by fixing the steel leveling keel 2 to the vertical surface of the building's interior wall 1. The steel leveling keel 2 ensures the flatness of the subsequent installation of the magnetic prefabricated wall panel 3, reduces assembly deviations, and improves the overall assembly accuracy of the wall surface. Next, according to the installation requirements of different areas in the large public venue, the weak magnetic inner plate 71 and the strong magnetic inner plate 72 are bonded to the back of the magnetic prefabricated wall panel 3 by pasting the outer layer 73, completing the assembly of the magnetic attraction component unit 7. Pasting the outer layer 73 ensures that the magnetic attraction component unit 7 is firmly connected to the magnetic prefabricated wall panel 3, and the weak magnetic inner plate 71 and the strong magnetic inner plate 72 can flexibly adapt to the magnetic attraction strength requirements of different areas. To enhance structural adaptability, the magnetic prefabricated wall panel 3 is magnetically connected to the steel leveling keel frame 2 via the magnetic component unit 7, quickly completing the assembly of a single magnetic prefabricated wall panel 3. The magnetic connection eliminates the need for wet work such as bolts and welding, significantly improving assembly efficiency and meeting the needs of rapid construction in large public venues. Finally, a joint sealant 8 is embedded between two adjacent magnetic prefabricated wall panels 3. The joint sealant 8 is made of flexible and wear-resistant material, and its thickness is adapted to the width of the gap between adjacent magnetic prefabricated wall panels 3. It can fill the gap, cover the splicing marks to improve the aesthetics of the wall surface, and also play a role in dust and moisture prevention, extending the service life of the structure. When the magnetic prefabricated wall panel 3 needs to be disassembled, first rotate the rotatable strip 53 in the side vertical slot 4. The side vertical slot 4 has an inclined groove 9 near the contact surface of the rotatable strip 53. The inclined groove 9 is adapted to the rotation trajectory of the rotatable strip 53, which can provide sufficient guiding space for the rotation of the rotatable strip 53, avoid jamming during rotation, and improve the ease of disassembly. During rotation, the anti-slip protrusion 54 can improve the grip strength when the person holds the rotatable strip 53. To avoid slippage during disassembly and reduce operational difficulty, the rotatable plate 53 is connected to the vertical shaft 51 via a self-returning hinge 52. The vertical shaft 51 is fixed on the protruding vertical block 50, which is fixedly connected to the vertical surface of the side vertical slot 4. When the rotatable plate 53 rotates, it drives the self-returning hinge 52 to rotate synchronously. A self-returning torsion spring is installed between the self-returning hinge 52 and the vertical shaft 51. At this time, the self-returning torsion spring is compressed, preparing for subsequent reset. When the rotatable strip 53 rotates to its limit position, the locking vertical shaft 61 on one side of the rotatable disassembly unit 5 rotates synchronously and locks into the locking vertical groove 63 on one side of the side vertical slot 4. The outer wall of the locking vertical shaft 61 is fixedly connected to a magnetic outer layer 62, and the inner wall of the locking vertical groove 63 is fixedly connected to a metal inner layer 60. At this time, the magnetic outer layer 62 and the metal inner layer 60 are magnetically connected, providing a temporary limiting force for the rotatable disassembly unit 5, making it convenient for the staff to exert force stably. The staff holds the rotatable strip 53 and pulls it outward. The rotatable strip 53 drives the magnetic assembled wall panel 3 to move synchronously, so that the magnetic suction component unit 7 is separated from the steel leveling keel frame 2, thereby completing the disassembly of the magnetic assembled wall panel 3. After disassembly, the rotatable plate 53 is released, and the self-returning torsion spring between the self-returning hinge 52 and the vertical shaft 51 returns to its original deformation, causing the self-returning hinge 52 and the rotatable plate 53 to automatically reset, so that the rotating and easy-to-disassemble unit 5 is usually hidden, which does not affect the overall aesthetics of the wall, and at the same time avoids accidental contact by unauthorized personnel, thus improving the safety of use.
