Description

Technical Field

[0001] This invention belongs to the field of prefabricated wall technology, specifically relating to a multifunctional prefabricated wall that can be quickly assembled and disassembled, and its installation method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In modern architecture, the requirements for the functionality and flexibility of walls are increasingly stringent. Traditional fixed wall structures often require complex demolition and reconstruction to meet the need for rapid connection between different rooms or areas, which is time-consuming and labor-intensive, and difficult to meet the needs of constructing rapid escape routes in emergency situations. Furthermore, traditional walls typically employ either exposed mounting or internal trenching for the installation and storage of pipes and cables. The former affects the building's aesthetics and poses safety hazards, while the latter compromises the structural stability of the wall and is also detrimental to future maintenance and renovation. While existing prefabricated wall systems improve installation efficiency to some extent, their connection devices have significant operational limitations, mostly restricting installation and disassembly to only one side of the wall. This not only limits construction convenience but also makes it difficult to quickly operate on the other side of the wall in emergencies such as fires or when doors and windows are locked. If one side of the wall is blocked by fire, it's impossible to quickly construct and adjust escape routes. Furthermore, existing prefabricated wall panels have a simple structure, making it difficult to create a systematic passageway for pipe and cable routing. Internal pipe maintenance is inconvenient, and the lack of flexibility in assembly and disassembly hinders rapid adjustments for local or overall situations, failing to meet diverse usage requirements. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a multifunctional prefabricated wall panel that can be quickly assembled and disassembled, and its installation method. This solves the problems of existing prefabricated wall panels having a simple structure, making it difficult to form a systematic channel structure, and lacking flexibility in assembly and disassembly, thus failing to make quick adjustments for local or overall situations.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a multifunctional prefabricated wall structure that can be quickly assembled and disassembled, comprising: columns, a top beam, two upper fixed walls, two lower fixed walls, and prefabricated wall panels; the columns and the top beam form a portal frame structure, the upper fixed walls are connected to the columns and the top beam respectively by connecting devices, the lower fixed walls are connected to the columns and the ground respectively by connecting devices, a first gap exists between the upper fixed walls and the lower fixed walls, and a second gap exists between adjacent upper fixed walls or lower fixed walls, the first gap and the second gap forming a cross-shaped structure, the prefabricated wall panels are fixed in the first gap and the second gap by connecting devices, and the prefabricated wall panels are hollow structures used to form multifunctional passage spaces.

[0006] As a further implementation, the connecting device is located inside the fixed wall and near the edge of the column, top beam, and ground. The connecting device is also located at the edge of the assembled wall panel. Positioning holes are provided on the side walls of the column, top beam, ground, and fixed wall. The connecting device consists of a positioning screw and a driving device. The axial direction of the positioning screw is arranged along the plane of the fixed wall and the assembled wall panel, and the positioning screw can extend out of the fixed wall and the assembled wall panel. The driving device drives the positioning screw to fix the fixed wall to the column and top beam, and fix the assembled wall panel to the fixed wall.

[0007] As a further implementation, the driving device includes a housing, on which two first bevel gears are rotatably disposed relative to the inner sidewall of the housing, and a second bevel gear is disposed between the first bevel gears. The positioning screw is disposed at the central axis position of the second bevel gear, and the positioning screw is threadedly connected to the second bevel gear for driving the positioning screw to extend and retract.

[0008] As a further implementation, the second bevel gear is rotatably mounted on the adjacent sidewall of the sidewall where the first bevel gear is located and meshes with the first bevel gear. One end of the positioning screw passes through the sidewall where the second bevel gear is located, and the other end is slidably provided with a guide post. The guide post is mounted on the opposite sidewall of the sidewall where the second bevel gear is located to prevent the positioning screw from rotating with the second bevel gear.

[0009] As a further implementation, a drive groove is provided at the rotation center axis of the first bevel gear, and an operating hole is provided on the fixed wall and the mounting wall plate. The operating hole corresponds to the position of the drive groove and is used to drive the first bevel gear to rotate by a tool.

[0010] As a further implementation, the operating hole is arranged perpendicular to the wall surface of the fixed wall and the assembled wall panel, and the fixed wall and the assembled wall panel are provided with a cover corresponding to the position of the operating hole.

[0011] As a further implementation, an auxiliary rod is provided on the outer side wall of the housing to correct the angle of the connecting device when prefabricating the fixed wall.

[0012] As a further implementation, the assembled wall panel consists of two cross-shaped prefabricated panels, and the connecting device is set on the edge of each prefabricated panel and fixed to both sides of the fixed wall through the connecting device; the cross-shaped prefabricated panel is a whole prefabricated panel. Alternatively, the cross-shaped prefabricated panel is composed of multiple prefabricated panels and a core panel, with connecting components also provided on the core panel, and positioning holes also provided on the side wall of the prefabricated panel.

[0013] As a further implementation, the joints between the assembled wall panels, fixed walls, top beams and columns are filled with a filling material.

[0014] Secondly, the present invention also provides an installation method for a quick-assembly and disassembly multifunctional prefabricated wall, comprising the following steps: S1. Fix the column to the ground, fix the top beam to the top of the column, and make positioning holes at the corresponding positions of the column, the top beam and the ground; S2. Place the fixed wall near the column, turn the drive device at the top and bottom of the fixed wall to insert the positioning screw into the positioning hole in the top beam and the ground, and then turn the drive device on the side of the fixed wall near the column to insert the positioning screw into the positioning hole on the column to complete the installation of the fixed wall. S3. When the cross-shaped prefabricated panel of the assembled wall panel is a whole prefabricated panel, the assembled wall panel is placed between two fixed walls and completely covers the space formed between the two fixed walls. The drive device on the side of the assembled wall panel close to the fixed wall is turned so that the positioning screw is inserted into the positioning hole on the fixed wall to realize the fixed installation of the assembled wall panel and complete the installation of the entire wall. When the cross-shaped prefabricated panel of the assembled wall panel is composed of multiple prefabricated panels and a core panel, the prefabricated panels are fixed in the first gap and the second gap by connecting components, the core panel is placed in the notch formed by the multiple prefabricated panels, and the driving device is turned to realize the fixed installation of the assembled wall panel and complete the installation of the entire wall.

[0015] Compared with the prior art, the advantages and positive effects of this invention are: The upper fixed wall of this invention is connected to the columns and top beams via connecting devices, and the lower fixed wall is connected to the columns and the ground via connecting devices, forming a multi-functional passage. The connecting devices enable rapid installation and disassembly of the assembled wall panels, facilitating quick connection between different rooms or areas for rapid escape, significantly improving disassembly efficiency. It also facilitates the installation, storage, and arrangement of pipes, cables, and equipment, making maintenance convenient. A first gap exists between the upper and lower fixed walls, and a second gap exists between adjacent upper or lower fixed walls, forming a cross-shaped structure for the assembled wall panels. The assembled wall panels are fixed in the first and second gaps by connecting devices. The assembled wall panels at the first and second gaps are hollow structures, forming a cross-shaped cavity. This creates a connecting passage structure between adjacent quick-assembly and disassembly walls. Corresponding holes are also provided on the columns or top beams at the first and second gaps, forming a mesh or straight passage structure. This can be used for the layout of pipes or power lines, not only protecting pipes or cables but also facilitating storage and maintenance. This allows the walls to be used not only for escape but also for other purposes.

[0016] The connecting device of the present invention can be operated from both sides, which can effectively enhance the connection stability between the fixed wall and the column or top beam. Since the connecting device can be operated from both sides, the first bevel gear can be driven by tools from both sides of the prefabricated wall. Alternatively, when the connecting device is installed on the prefabricated panel where an escape route needs to be established, the prefabricated wall panel can be removed from one side of the prefabricated wall, and then the prefabricated wall panel on the back of the wall can be removed to quickly establish an escape route. The prefabricated wall panel can also be installed from the other side of the prefabricated wall, which can effectively prevent the further spread of dangerous sources such as fire.

[0017] The prefabricated wall panel of the present invention consists of two cross-shaped prefabricated panels, which are fixed to both sides of a fixed wall by connecting devices. The cross-shaped prefabricated panel is a whole prefabricated panel, or it is composed of multiple prefabricated panels and a core panel. The core panel is provided with connecting components, and the side wall of the prefabricated panel is provided with positioning holes. This allows the prefabricated wall panel to be disassembled only for different situations during actual use, making the wall panel highly operable and the disassembly and assembly process simple and convenient.

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a multi-functional prefabricated wall structure that can be quickly assembled and disassembled, such as... Figures 1-2As shown, the structure comprises: a column 1, a top beam 2, two upper fixed walls 3, two lower fixed walls 6, and assembled wall panels 4. The column 1 and the top beam 2 form a U-shaped frame structure. The upper fixed walls 3 are connected to the column 1 and the top beam 2 respectively via connecting devices 5. The lower fixed walls 6 are connected to the column 1 and the ground respectively via connecting devices 5. There is a first gap between the upper fixed walls 3 and the lower fixed walls 6, and a second gap between adjacent upper fixed walls 3 or lower fixed walls 6. The first gap and the second gap form a cross-shaped structure. The assembled wall panels 4 are fixed in the first gap and the second gap via connecting devices 5. The assembled wall panels 4 are hollow structures used to form a multi-functional passageway via connecting devices 5. The assembly wall panel 4 enables rapid installation and disassembly, facilitating quick connection between different rooms or areas and facilitating rapid escape. This significantly improves disassembly efficiency. Furthermore, the assembly wall panel 4 at the first and second gaps is hollow, forming a cross-shaped cavity that creates a connecting passageway between adjacent quick-assembly and disassembly walls. Corresponding holes are also provided on the columns 1 or top beams 2 at the first and second gaps, creating a mesh or linear passageway that can be used for pipe or power line installation. This not only protects pipes or cables but also facilitates storage and maintenance, allowing the wall to function not only for escape but also for the installation and storage of pipes and cables.

[0023] The connecting device 5 is located inside the fixed wall 6 and near the edge of the column 1, the top beam 2, and the ground. The connecting device 5 is also located at the edge of the assembled wall panel 4. Positioning holes are provided on the side walls of the column 1, the top beam 2, the ground, and the fixed wall 6. The connecting device 5 consists of a positioning screw 9 and a driving device. The axial direction of the positioning screw 9 is arranged along the plane of the fixed wall 6 and the assembled wall panel 4, and the positioning screw 9 can extend out of the fixed wall 6 and the assembled wall panel 4. The driving device drives the positioning screw 9 to fix the fixed wall to the column 1 and the top beam 2, and fix the assembled wall panel 4 to the fixed wall. The positioning screw 9 is driven by a drive device to insert into the column 1 and the top beam 2, thereby fixing the fixed wall to the column 1 and the top beam 2. Similarly, the positioning screw 9 is driven by a drive device to insert into the fixed wall 6, and the assembled wall panel 4 is fixed to the fixed wall 6. Only the drive device needs to be operated to fix and disassemble the fixed wall and the assembled wall, significantly improving disassembly efficiency and increasing the success rate of escape. The number of positioning holes is the same as the number of connecting devices 5, used to cooperate with the positioning screw 9 to position and tighten the fixed wall and the assembled wall panel. Since the connecting device 5 can be operated from both sides, the first bevel gear 7 can be driven from both sides of the assembled wall. This allows the assembled wall panel 4 to be disassembled from one side of the assembled wall for the installation of cable assemblies for pipes or power grids, while the assembled wall panel 4 can be installed from the other side of the assembled wall. In the event of a fire, this effectively prevents the further spread of fire sources and other hazards.

[0024] As a further implementation, the driving device includes a housing 13, on which two first bevel gears 7 are rotatably disposed relative to the inner sidewall of the housing 13. A second bevel gear 8 is also disposed between the first bevel gears 7. The positioning screw 9 is disposed at the central axis of the second bevel gear 8. The positioning screw 9 is threadedly connected to the second bevel gear 8 and is used to drive the positioning screw 9 to extend and retract. By driving the first bevel gear 7 on one side with a tool, the first bevel gear 7 and the second bevel gear 8 mesh with each other, thereby driving the positioning screw 9 to extend and retract. This solves the problem that the bolts and nuts in the traditional connection structure rotate at the same time, making it impossible to disassemble the assembled wall panel 4.

[0025] As a further implementation, the second bevel gear 8 is rotatably mounted on the adjacent sidewall of the sidewall where the first bevel gear 7 is located. One end of the positioning screw 9 passes through the sidewall where the second bevel gear 8 is located, and the other end is slidably provided with a guide post 11. The guide post 11 is located on the opposite sidewall of the sidewall where the second bevel gear 8 is located, which is used to prevent the positioning screw 9 from rotating with the second bevel gear 8, thus ensuring the transmission reliability between the first bevel gear 7 and the second bevel gear 8. Since the contact between the bevel gears is a line contact, the sticking situation caused by corrosion between the bevel gears is avoided. In addition, the connecting device 5 is located inside the fixed wall, which avoids the failure of the connecting device 5 due to erosion by rainwater, etc., ensuring that the positioning screw 9 can maintain normal function and realize the effective disassembly between the assembled wall panels 4, thereby ensuring the success rate of escape.

[0026] As a further implementation, a drive groove 12 is provided at the rotation center axis of the first bevel gear 7, and an operating hole is provided on the fixed wall and the mounting wall panel. The operating hole corresponds to the position of the drive groove 12 and is used to drive the first bevel gear 7 to rotate by a tool. The shape of the drive groove 12 can be a cross structure or a slotted structure. The first bevel gear 7 can be driven by a cross screwdriver or a slotted screwdriver, which reduces the requirements of the device for disassembly tools. In addition, the first bevel gear 7 can also be driven by an electric wrench to improve the disassembly efficiency of the mounting wall panel 4.

[0027] As a further implementation, the operating hole is arranged perpendicular to the wall surface of the fixed wall and the assembled wall panel, and the fixed wall and the assembled wall panel are provided with a cover corresponding to the position of the operating hole. By providing the cover, the erosion of the connecting device 5 by rainwater or other corrosive substances can be effectively prevented, thus effectively preventing the functional failure of the connecting device 5.

[0028] As a further implementation, an auxiliary rod 10 is provided on the outer side wall of the outer casing 13 for correcting the angle of the connecting device 5 and assisting in fixing during the prefabrication of the fixed wall.

[0029] As a further implementation, the assembled wall panel 4 is composed of two cross-shaped prefabricated panels, and the connecting device is set on the edge of each prefabricated panel and fixed to both sides of the fixed wall by the connecting device 5 respectively; the cross-shaped prefabricated panel is a whole prefabricated panel. Alternatively, the cross-shaped prefabricated panel is composed of multiple prefabricated panels and a core panel, with connecting components also provided on the core panel, and positioning holes provided on the side wall of the prefabricated panel; only the local assembly wall panel 4 needs to be disassembled.

[0030] As a further implementation, the joints between the assembled wall panel 4, the fixed wall, the top beam 2, and the column 1 are filled with filling material to seal the wall.

[0031] Example 2 This embodiment provides a method for installing a multifunctional prefabricated wall structure that allows for quick assembly and disassembly, including the following steps: S1. The column 1 is fixed on the ground, which can be fixed by concrete pouring. The top beam 2 is fixed on the top of the column 1. The top beam 2 and the column 1 can be prefabricated as an integrated unit or connected by splicing on the construction site. Positioning holes are opened at the corresponding positions of the column 1, the top beam 2 and the ground. S2. Place the fixed wall near the column 1, turn the drive device at the top and bottom of the fixed wall to insert the positioning screw 9 into the positioning hole of the top beam 2 and the ground, then turn the drive device on the side of the fixed wall near the column 1 to insert the positioning screw 9 into the positioning hole on the column 1, drive the first bevel gear 7 with a Phillips screwdriver or a flathead screwdriver, or drive the first bevel gear 7 with an electric wrench to realize the installation of the fixed wall; S3. When the cross-shaped prefabricated panel of the assembly wall panel 4 is a whole prefabricated panel, the assembly wall panel 4 is placed between two fixed walls and completely covers the space formed between the two fixed walls. The drive device on the side of the assembly wall panel 4 near the fixed wall 6 is turned so that the positioning screw is inserted into the positioning hole on the fixed wall 6, thereby realizing the fixed installation of the assembly wall panel 4 and completing the installation of the entire wall. When the cross-shaped prefabricated panel of the assembled wall panel 4 is composed of multiple prefabricated panels and a core panel, the prefabricated panels are fixed in the first gap and the second gap by connecting components, the core panel is placed in the notch formed by the multiple prefabricated panels, and the driving device is turned to realize the fixed installation of the assembled wall panel 4. The first bevel gear 7 is driven by a Phillips screwdriver or a flathead screwdriver, or by an electric wrench, to realize the installation of the assembled wall panel 4 and complete the installation of the entire wall.

[0032] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
