Description

Technical Field

[0001] This invention belongs to the field of prefabricated wall technology, specifically relating to a prefabricated wall for rapid escape 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 the field of building construction, walls are an important component of buildings. Currently, the construction of walls mainly adopts two methods: on-site assembly of precast cast-in-place components and on-site installation and masonry of whole blocks. When using precast cast-in-place components for on-site assembly, the large number of precast components necessitates precise hoisting equipment and skilled installation personnel. Furthermore, the complex and time-consuming processes of splicing and securing the various components result in slow construction progress. Additionally, these precast components are often quite heavy, increasing the overall load on the building and creating inconvenience for transportation and installation.

[0004] In addition, when precast concrete components are assembled on-site, they are difficult to disassemble quickly in emergencies such as fires and earthquakes because the wall structure is relatively fixed and heavy. At the same time, the existing precast concrete component connectors are prone to corrosion and rust, or are fixed by snap-fit ​​structures. This makes it very easy for the connectors to rust and fail in emergencies, or require sequential disassembly from specific locations, violent and destructive disassembly, or even failure to disassemble in an emergency, making it impossible to establish an effective escape route in time, which seriously threatens the lives of people. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a prefabricated wall structure for rapid escape and its installation method. It solves the problems of existing prefabricated walls having rusted and failed connectors, making disassembly difficult, or requiring sequential disassembly from specific locations or forceful destructive disassembly, thus failing to establish an effective escape route in a timely manner. At the same time, it also enables effective isolation of hazardous sources by disassembling from one side and then installing from the other side.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a prefabricated wall for rapid escape, comprising: two columns set on the ground, a top beam, two fixed walls, and an assembled wall panel; the columns and the top beam form a portal frame structure, each of the fixed walls is connected to the columns, the top panel, and the ground through a connecting device, there is a certain distance between the two fixed walls, and the assembled wall panel is provided between the two fixed walls, and the fixed walls and the assembled wall panel are connected by a connecting device; The connecting device consists of a telescopic rod and a driving device. The axial direction of the telescopic rod is arranged along the plane of the fixed wall, and the telescopic rod can extend out of the fixed wall. The driving device drives the telescopic rod to fix the fixed wall to the column and the top beam, and fixes the assembled wall panel to the fixed wall.

[0007] As a further implementation, the connecting device is located at the edge of the fixed wall and the assembled wall panel; the column, the top beam and the side wall of the fixed wall are provided with positioning holes for use with the telescopic rod to position and tighten the fixed wall.

[0008] As a further implementation, the driving device includes a housing, on which two driving bevel gears are rotatably disposed relative to the inner sidewall of the housing, and a driven bevel gear is disposed between the driving bevel gears. The telescopic rod is disposed at the central axis position of the driven bevel gear, and the telescopic rod is threadedly connected to the driven bevel gear for driving the telescopic rod to extend and retract.

[0009] As a further implementation, the driven bevel gear is rotatably mounted on the adjacent side wall of the side wall where the driving bevel gear is located. One end of the telescopic rod passes through the side wall where the driven bevel gear is located, and the other end is slidably provided with a diamond-shaped limiting rod. The limiting rod is mounted on the opposite side wall of the side wall where the driven bevel gear is located to prevent the telescopic rod from rotating with the driven bevel gear.

[0010] As a further implementation, the drive bevel gear is provided with a drive groove, and the fixed wall and the mounting wall plate are provided with an operating hole. The operating hole corresponds to the position of the drive groove, so that the tool can be sent to the drive groove through the operating hole, thereby driving the drive bevel gear to rotate.

[0011] 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.

[0012] As a further implementation, the assembled wall panel is a hollow structure composed of two prefabricated panels, and there are two assembled wall panels that are stacked or joined together.

[0013] As a further implementation, the connecting device is located at the edge of the prefabricated panel.

[0014] As a further implementation, the joints between the assembled wall panels, fixed walls, top beams and columns are filled with a filling material.

[0015] Secondly, the present invention also provides a method for installing a prefabricated wall for rapid escape, 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 telescopic rod 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 telescopic rod into the positioning hole on the column to complete the installation of the fixed wall. S3. Place the assembled wall panel between two fixed walls, completely covering the space formed between the two fixed walls. Turn the drive device on the side of the assembled wall panel closest to the fixed wall to insert the telescopic rod into the positioning hole on the fixed wall, thereby realizing the installation of the assembled wall panel and completing the installation of the entire wall.

[0016] Compared with the prior art, the advantages and positive effects of this invention are: The present invention connects the fixed wall and the assembled wall panel via a connecting device, enabling rapid installation and disassembly of the assembled wall panel. This facilitates quick connection between different rooms, achieving rapid escape and significantly improving disassembly efficiency. It effectively avoids the problem of inability to quickly disassemble in emergencies due to connector failure in traditional assembled walls. The telescopic rod of the connecting device is axially arranged along the plane of the fixed wall and extends beyond it. A drive device drives the telescopic rod to extend and retract. Because the drive device is located within the fixed wall and the telescopic rod extends beyond it, it can be inserted into adjacent structural elements. The drive device drives the telescopic rod into columns and beams, thus fixing the fixed wall to these elements. The drive device is also located within the assembled wall panel. By driving the telescopic rod into the fixed wall, it fixes the assembled wall panel to the fixed wall. Only the drive device needs to be operated to achieve single-sided fixing and disassembly of the fixed and assembled walls, significantly improving disassembly efficiency, rapidly establishing a one-way escape route, and increasing the success rate of escape.

[0017] The connecting device of this invention can be operated from both sides, allowing two connecting devices to be installed side-by-side at the same location inside the fixed wall. Positioning holes are provided on the column, fixed wall, and top beam, with the number of holes matching the number of connecting devices. These holes are used to position and tighten the fixed wall in conjunction with the telescopic rod. Because the connecting device can be operated from both sides, the drive bevel gear can be driven from both sides of the prefabricated wall using tools. This allows the prefabricated wall panel to be disassembled on one side and then installed from the other side, effectively preventing the further spread of hazards such as fire.

[0018] The present invention features two rotatable drive bevel gears on the inner sidewall of the housing, with a driven bevel gear positioned between them. A telescopic rod is located at the central axis of the driven bevel gear, and the telescopic rod is threadedly connected to the driven bevel gear. The drive and driven bevel gears mesh with each other, allowing the drive bevel gear to rotate and thus drive the telescopic rod to extend and retract. This solves the problem of bolts and nuts rotating simultaneously in traditional connectors, preventing the assembly wall panel from being disassembled. Simply turning the drive bevel gear disassembles the connection between the fixed wall and the assembly wall panel. The driven bevel gear can... The telescopic rod is rotatably mounted on the adjacent side wall of the side wall where the driving bevel gear is located. One end of the telescopic rod passes through the side wall where the driven bevel gear is located, and the other end is slidably mounted with a diamond-shaped limiting rod. The limiting rod is mounted on the opposite side wall of the side wall where the driven bevel gear is located to prevent the telescopic rod from rotating with the driven bevel gear. Since the contact between the bevel gears is a line contact, the transmission reliability between the driving bevel gear and the driven bevel gear is guaranteed, and the sticking of the bevel gears due to corrosion is avoided. In addition, the connecting device is located inside the fixed wall to prevent the connection device from failing due to rainwater or other corrosion, ensuring that the telescopic rod can maintain normal function.

[0022] 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.

[0023] 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 prefabricated wall structure for rapid escape, such as... Figures 1-2 As shown, it comprises: two columns 1 set on the ground, a top beam 2, two fixed walls 3, and assembled wall panels 4; the columns 1 and the top beam 2 form a portal frame structure, each of the fixed walls 3 is connected to the columns 1, the top plate, and the ground through a connecting device 5, and there is a certain distance between the two fixed walls 3 to serve as an escape passage, and the assembled wall panels 4 are set between the two fixed walls 3. The fixed walls 3 and the assembled wall panels 4 are connected by the connecting device 5, which enables the quick installation and quick disassembly of the assembled wall panels 4, so as to realize the quick connection between different rooms and achieve the purpose of rapid escape. This significantly improves the disassembly efficiency and can effectively avoid the problem of failure of the connectors of traditional prefabricated walls, which leads to the inability to quickly disassemble them in an emergency. The connecting device 5 comprises a telescopic rod 9 and a driving device. The axial direction of the telescopic rod 9 is arranged along the plane of the fixed wall 3, and the telescopic rod 9 can extend out of the fixed wall 3. The telescopic rod 9 is driven to extend and retract by the driving device. Since the driving device is set in the fixed wall 3 and the telescopic rod 9 can extend out of the fixed wall 3, the telescopic rod 9 can be inserted into adjacent solid structures. For example, the telescopic rod 9 can be inserted into the column 1 and the top beam 2 by the driving device, thereby fixing the fixed wall 3 to the column 1 and the top beam 2. Or, the telescopic rod 9 can be inserted into the assembled wall panel 4 by the driving device, and the assembled wall panel 4 can be fixed to the fixed wall 3. Only the driving device needs to be operated to realize the fixing and disassembly of the fixed wall 3 and the assembled wall, which significantly improves the disassembly efficiency and increases the success rate of escape.

[0024] As a further implementation, the connecting device 5 is located at the edge inside the fixed wall 3 and the assembled wall panel 4. Since the connecting device 5 can be operated from both sides, two connecting devices 5 can be arranged side by side at the same position inside the fixed wall 3. The column 1, the fixed wall 3, and the top beam 2 are provided with positioning holes, the number of which is the same as the number of connecting devices 5. These holes are used to cooperate with the telescopic rod 9 to position and tighten the fixed wall 3. The side-by-side arrangement of two connecting devices 5 can effectively enhance the connection stability between the fixed wall 3 and the column 1 or the top beam 2. Since the connecting device 5 can be operated from both sides, the drive bevel gear 7 can be driven from both sides of the assembled wall. This means that after the assembled wall panel 4 is removed from one side of the assembled wall, it can be installed from the other side, which can effectively prevent the further spread of dangerous sources such as fire.

[0025] As a further implementation, the driving device includes a housing 6, on which two driving bevel gears 7 are rotatably mounted relative to the inner sidewall of the housing 6. A driven bevel gear 8 is also provided between the driving bevel gears 7. The telescopic rod 9 is located at the central axis of the driven bevel gear 8. The telescopic rod 9 is threadedly connected to the driven bevel gear 8 and is used to drive the telescopic rod 9 to extend and retract. Specifically, by driving the driving bevel gear 7 with a tool on one side, the driving bevel gear 7 and the driven bevel gear 8 mesh with each other, thereby driving the driven bevel gear 7 to rotate the driven bevel gear 8, and thus driving the telescopic rod 9 to extend and retract. This solves the problem that the bolt and nut of traditional connectors rotate simultaneously, making it impossible to disassemble the assembled wall panel 4. The connection between the fixed wall 3 and the assembled wall panel 4 can be released simply by turning the driving bevel gear 7. An auxiliary handle 10 is provided on the outer sidewall of the housing 6 for auxiliary positioning or fixing of the connecting device 5 when prefabricating the fixed wall 3.

[0026] As a further implementation, the driven bevel gear 8 is rotatably mounted on the adjacent side wall of the side wall where the driving bevel gear 7 is located. One end of the telescopic rod 9 passes through the side wall where the driven bevel gear 8 is located, and the other end is slidably provided with a diamond-shaped limiting rod 11. The limiting rod 11 is set on the opposite side wall of the side wall where the driven bevel gear 8 is located to prevent the telescopic rod 9 from rotating with the driven bevel gear 8, thus ensuring the transmission reliability between the driving bevel gear 7 and the driven 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 wall and has a cover to prevent the connection device 5 from failing due to rainwater or other corrosion, ensuring that the telescopic rod 9 can maintain normal function and realize the rapid and effective disassembly of the assembled wall panel 4, thereby ensuring the success rate of escape.

[0027] As a further implementation, the drive bevel gear 7 is provided with a drive groove 12, and the fixed wall 3 and the mounting wall panel 4 are provided with operating holes. The operating holes correspond to the position of the drive groove 12, which facilitates the feeding of tools to the drive groove 12 through the operating holes, thereby driving the drive bevel gear 7 to rotate. The shape of the drive groove 12 can be a cross structure or a slotted structure. The drive 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 drive bevel gear 7 can also be driven by an electric wrench to improve the disassembly efficiency of the mounting wall panel 4.

[0028] As a further implementation, the operating hole is arranged perpendicular to the wall surface of the fixed wall 3 and the mounting wall panel 4, and the fixed wall 3 and the mounting wall panel 4 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, and the functional failure of the connecting device 5 can be effectively prevented.

[0029] As a further implementation, the assembled wall panel 4 is a hollow structure composed of two prefabricated panels. There are two assembled wall panels 4, which are stacked or connected vertically. In specific implementation, the assembled wall panel 4 can be two panels, so that the core of the assembled wall panel 4 is a hollow structure. If the assembled wall panel 4 adopts a hollow structure, at least two connecting devices 5 need to be set at both ends of the wall panel to control the two panels respectively. The hollow structure can realize functions such as wiring and equipment placement.

[0030] As a further implementation, the connecting device 5 is located at the edge of the prefabricated panel. If the wall is high, the connecting device 5 on one of the assembled wall panels 4 can be rotated to disassemble the partial wall panel.

[0031] As a further implementation, the joints between the assembled wall panel 4, the fixed wall 3, the top beam 2 and the column 1 are filled with filling material to seal the wall.

[0032] Example 2 This embodiment provides a method for installing a prefabricated wall for rapid escape, 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 3 near the column 1, turn the drive device at the top and bottom of the fixed wall 3 to insert the telescopic rod 9 into the positioning holes of the top beam 2 and the ground, then turn the drive device on the side of the fixed wall 3 near the column 1 to insert the telescopic rod 9 into the positioning hole on the column 1, drive the drive bevel gear 7 with a Phillips screwdriver or a flathead screwdriver, or drive the drive bevel gear 7 with an electric wrench to realize the installation of the fixed wall 3; S3. Place the assembled wall panel 4 between the two fixed walls 3, completely covering the space formed between the two fixed walls 3. Twist the drive device on the side of the assembled wall panel 4 closest to the fixed wall 3 so that the telescopic rod 9 is inserted into the positioning hole on the fixed wall 3. Drive the drive bevel gear 7 with a Phillips screwdriver or a flathead screwdriver, or drive the drive bevel gear 7 with an electric wrench to realize the installation of the assembled wall panel 4 and complete the installation of the entire wall.

[0033] 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.
