The first hollow window unit 32 has a window opening 321. The first hollow window unit 32 includes a clamping plate 181. The sealing film 37 includes multiple first film holes 371 corresponding to the window opening 321. The first film holes 371 are aligned with the window opening 321.

The fourth fastener 1873 passes through the clamping plate 181 and the sealing film 37 to fix the clamping plate 181 and the sealing film 37 to the first hollow window unit 32.

[0049] In this embodiment of the invention, the sealing connection structure includes a window frame 182 fixed at the window opening 321, a glass support frame 183 disposed inside the window frame 182, a first sealing strip 184 embedded in the glass support frame 183, and a pressure frame 185 for pressing the glass onto the first sealing strip 184. The glass support frame 183 is connected to the window frame 182 by a second fastener 1872, and the pressure frame 185 is connected to the glass support frame 183 by a third fastener 1871.

The sealing film 37 covers the gap between the third frame 1833 and the first hollow window unit 32.

[0051] Combination Figure 8 and Figure 9In this embodiment of the invention, the second module unit includes a hollow door unit 33 and a plurality of second hollow window units 34. The hollow door unit 33 and the plurality of second hollow window units 34 are arranged in sequence and detachably connected. The hollow door unit 33 has a door opening 331. The hollow door unit 33 includes a door frame 175. The sealing membrane 37 includes a second membrane hole 372 corresponding to the door opening 331. The second membrane hole 372 is aligned with the door opening 331. The sealing membrane 37 is squeezed from both sides by the door frame 175 and one side plate of the hollow door unit 33. The fifth fastener 1875 passes through the door frame 175 and the sealing membrane 37 to fix the door frame 175 and the sealing membrane 37 to the hollow door unit 33.

[0052] In this embodiment of the invention, the inner wall of the door opening 331 is provided with a plurality of door inner hand holes 173, and the side of the hollow door unit 33 is provided with a plurality of door side connection holes 174. The door inner hand holes 173 communicate with the door side connection holes 174. The door inner hand holes 173 are used for the passage of the first fastener 38. The door side connection holes 174 and the second hollow window unit 34 are detachably connected through the first fastener 38.

[0053] In this embodiment of the invention, the hollow door unit 33 includes a door leaf 176 and a first airtight connection mechanism. The door leaf 176 is installed inside the door opening 331. The first airtight connection mechanism is used to seal and connect the door leaf 176 and the hollow door unit 33.

[0054] In the entire hollow door unit 33, the first airtight connection structure is used to seal the installed door leaf to ensure the airtightness of the doorway area. In practical applications, the hollow door unit 33 and the pressurized chamber it constitutes provide a solution that can be disassembled into small-sized components, is lightweight to adapt to floor load-bearing capacity, is easy to assemble, and has reliable structural strength through modular, lightweight, integrated molding, and reliable airtight connection design. This not only effectively solves many limitations of existing pressurized chambers in existing building operation scenarios, but also achieves flexible deployment and efficient utilization of the pressurized chamber while ensuring structural strength and sealing performance.

[0055] Furthermore, in some embodiments, a hollow door unit 33 with an integrally molded fiberglass structure is proposed. However, in practical applications, a single integrally molded fiberglass structure may have problems such as insufficient rigidity, easy deformation, and poor thermal insulation performance when subjected to pressure difference between the inside and outside of the pressurized chamber, external impact, or long-term load, thereby affecting the overall structural stability and service life of the hollow door unit 33.

[0056] The hollow door unit 33 includes an inner panel, an outer panel, and a surrounding panel connecting the inner panel and the outer panel. The inner panel, the outer panel, and the surrounding panel form a hollow sandwich box structure. Reinforcing members are provided on the inner panel and the outer panel.

[0057] Specifically, the hollow door unit 33 consists of an inner panel, an outer panel, and a surrounding panel. Meanwhile, for the inner and outer panels, reinforcing members can be introduced to improve their local stiffness and strength, such as by attaching them to the panel surface in a strip or mesh pattern or by integrally molding them.

[0058] In practical applications, by designing the hollow door unit 33 as a hollow sandwich box structure and supplementing it with reinforcing components, the structural performance of the hollow door unit 33 is significantly improved. The hollow door unit 33 consists of an inner panel, an outer panel, and a surrounding panel, which together form a closed hollow cavity. When the hollow door unit 33 is applied to a pressurized cabin, the inner and outer panels bear the pressure difference between the inside and outside of the cabin, while the surrounding panel transmits the pressure difference to the entire box structure. The hollow sandwich box structure utilizes the high bending stiffness of the inner and outer panels, effectively resisting bending deformation through a large cross-sectional height, thereby significantly improving the overall stiffness and compressive strength of the hollow door unit 33 while maintaining lightweight design. Furthermore, the reinforcing components on the inner and outer panels further enhance the local stiffness of the panels, effectively preventing local buckling or deformation under pressure, ensuring the flatness of the panels and the stability of the structure.

[0059] Furthermore, in some embodiments, the proposed hollow door unit 33 for the pressurized chamber is integrally molded from fiberglass and has a hollow sandwich box structure. Reinforcing members are provided on the inner and outer panels, and a first airtight connection structure is provided for the door panel connection. However, during the operation of the pressurized chamber, the structural stability, deformation resistance, and support strength of the hollow sandwich box structure may face challenges when subjected to internal and external pressure differences, especially under long-term use or extreme operating conditions, which may affect the overall airtightness and safety.

[0060] In response, a hollow sandwich box structure was proposed, with the interior filled with rigid polyurethane foam to form a core material board, and a first airtight connection structure running through the inner panel, the core material board, and the reinforcing members.

[0061] Specifically, by filling the hollow sandwich box structure with rigid polyurethane foam to form a core material board, the originally hollow structure is transformed into a composite structure with solid filling. Rigid polyurethane foam has excellent adhesion and mechanical properties, enabling it to form a unified whole with the inner and outer panels and reinforcements, thereby significantly improving the overall stiffness, bending resistance, and impact resistance of the hollow door unit 33. This not only enhances the stability of the structure but also provides a more solid supporting foundation for the first airtight connection structure.

[0062] In this embodiment of the invention, the first airtight connection structure includes: a metal connector pre-embedded inside the hollow door unit 33, the metal connector having a threaded blind hole; a door frame 175, through which a first set of fasteners passes through the door frame 175 and engages with the threaded blind hole of the metal connector, thereby pressing and fixing the door frame 175 to the inside of the hollow door unit 33; and a sealing film 37 disposed on the contact surface between the door frame 175 and the hollow door unit 33.

[0063] Specifically, by combining the metal connectors pre-embedded inside the hollow door unit 33 with the door frame 175, the first set of fasteners, and the sealing membrane 37, a first airtight connection structure is constructed between the door leaf 176 and the hollow door unit 33. Simultaneously, the door frame 175 achieves a rotatable connection with the door leaf 176 through a hinge seat and a hinge mounted on itself. The opening and closing of the door frame 175 is achieved by the rotation of the hinge on the hinge seat.

[0064] In practical applications, the fiberglass hollow door unit 33 adopts an integral molding structure, which has good structural strength. However, achieving a reliable seal by directly making high-strength threaded connections on the fiberglass presents a challenge. By pre-embedding metal connectors during the molding of the hollow door unit 33 and providing threaded blind holes inside, a robust and reusable metal threaded connection point is provided for the subsequent installation of the door frame 175. This avoids the problems of insufficient thread strength or damage that may occur when directly tapping the fiberglass material. The door frame 175 is placed around the door opening inside the hollow door unit 33, and the sealing film 37 is precisely set on the contact surface between the door frame 175 and the hollow door unit 33. Subsequently, the first set of fasteners passes through the reserved holes on the door frame 175 and mates with the threaded blind holes of the pre-embedded metal connectors. A corresponding sealant is also provided between the first set of fasteners and the threaded blind holes to improve the airtightness between the first set of fasteners and the threaded blind holes. When the first set of fasteners is tightened, they not only securely fix the door frame 175 to the hollow door unit 33, but also apply a uniform clamping force to the sealing membrane 37. This clamping force causes the sealing membrane 37 to be compressed and deformed, thereby effectively filling the tiny gaps and uneven areas between the contact surfaces of the door frame 175 and the hollow door unit 33, forming a continuous and reliable airtight barrier.

[0065] Furthermore, in some embodiments, the first airtight connection structure of the hollow door unit 33 achieves sealing by setting a sealing membrane 37 between the door frame 175 and the hollow door unit 33. However, in practical applications, a single sealing element may experience a decline in sealing performance due to factors such as material aging, installation errors, or uneven long-term stress, especially under high pressure or variable pressure environments, posing a potential risk of micro-leakage, thereby affecting the overall airtightness and safety of the pressurized chamber.

[0066] To address this, a sealing membrane 37 is laid on the inner surface of the hollow door unit 33 and clamped between the door frame 175 and the hollow door unit 33, and is pressed and sealed by a first set of fasteners. The sealing membrane 37 is a thin sheet material with good flexibility and ductility, used to provide an additional sealing barrier to enhance the reliability of the airtight connection.

[0067] Furthermore, in some embodiments, the sealing membrane 37 achieves sealing through physical clamping. However, in practical applications, due to minor unevenness, processing errors, or micro-movements during long-term operation on the surface of the component, relying solely on the physical compression of the sealing membrane 37 may not be sufficient to guarantee ultimate airtightness and long-term sealing stability. Especially in high-pressure or frequently opening and closing environments, there may still be a risk of gas infiltration.

[0068] To address this, a sealant layer is applied between the sealing membrane 37 and the door frame 175, and between the sealing membrane 37 and the hollow door unit 33. Specifically, the sealant layer is a viscoelastic material used to fill tiny gaps at the connection interface, bond surfaces, and provide additional sealing functionality, thereby effectively preventing gas or liquid leakage through the connection interface.

[0069] In practical applications, the sealing reliability of the first airtight connection structure is significantly improved by introducing a sealant layer between the sealing membrane 37 and the door frame 175, and between the sealing membrane 37 and the hollow door unit 33. When the first set of fasteners presses the door frame 175, the sealant layer can flow fully under pressure and fill any tiny gaps or uneven surfaces that may exist between the sealing membrane 37 and the door frame 175, and between the sealing membrane 37 and the hollow door unit 33. Due to its inherent viscoelasticity and good adhesion to materials, the sealant layer not only forms an additional sealing barrier, but also firmly bonds the sealing membrane 37 to the adjacent door frame 175 and hollow door unit 33, thereby constructing a more continuous, stable, and less susceptible to external factors in the sealing interface.

[0070] Furthermore, in some embodiments, the hollow door unit 33 includes multiple bolt holes on the surrounding panel, inner panel, and outer panel, as well as bolts and nuts for use with adjacent hollow door units 33; sealant is provided on the installation path of the bolt holes, and the bolts or nuts press the sealant together when locked.

[0071] Specifically, multiple bolt holes are through holes provided on the surrounding panels, inner panels, and outer panels of the hollow door unit 33, providing a path for mechanical fasteners to pass through, thereby realizing the physical connection between adjacent modules. These bolt holes can be pre-drilled holes during the integral molding of the fiberglass modules, or they can be formed by drilling or other methods after the modules are formed.

[0072] Furthermore, in some embodiments, this application further proposes a second airtight connection structure between the door leaf 176 and the door frame 175. The second airtight connection structure includes a sealing groove on the door frame 175, an elastic sealing strip 177 embedded in the sealing groove, and a locking mechanism on the door leaf 176. The locking mechanism acts on the door leaf 176 to press the elastic sealing strip 177.

[0073] Specifically, the second airtight connection structure is a key component specifically designed to establish reliable airtightness between the door leaf 176 and the door frame 175. Through mechanical action and the cooperation of elastic materials, it effectively blocks gas leakage paths. Here, by providing a second airtight connection structure between the door leaf 176 and the door frame 175 of the aforementioned hollow door unit 33, the sealing integrity of the door leaf 176 when closed is ensured.

[0074] For example, when the door leaf 176 is closed, the sealing groove on the door frame 175 provides a precise installation position and support for the elastic sealing strip 177. When the locking mechanism on the door leaf 176 is operated, it not only fixes the door leaf 176 in the closed position, but more importantly, it acts on the door leaf 176, causing it to move towards the door frame 175 and applying a continuous compressive force to the elastic sealing strip 177 embedded in the sealing groove. Under the action of the compressive force, the elastic sealing strip 177 undergoes elastic deformation, fully filling the tiny gaps and irregular surfaces between the door leaf 176 and the door frame 175, thereby forming a continuous and reliable airtight barrier.

[0075] Furthermore, in combination Figure 10 The second module unit includes a hollow door unit 33 and multiple second hollow window units 34, which are arranged sequentially and detachably connected. Another second module unit includes two detachably connected second hollow sub-panels 35 and multiple third hollow sub-panels 36. The two second hollow sub-panels 35 and the multiple third hollow sub-panels 36 are arranged and spliced ​​sequentially to form the second module unit. The multiple third hollow sub-panels 36 are located between the two second hollow sub-panels 35. The structure of the second hollow sub-panel 35 is largely the same as that of the hollow door unit 33, except that the second hollow sub-panel 35 does not contain a door opening 331. The structure of the third hollow sub-panel 36 is the same as that of the first hollow sub-panel 31.

[0076] For further details, please refer to [link / reference]. Figure 11 In this embodiment of the invention, the two first module units are a top module unit and a bottom module unit, respectively. The second panel 12 of the first hollow sub-board 31 on both first module units is rectangular, and the length of the second panel 12 in the second direction is greater than the length of the second panel 12 in the first direction. That is, the side of the second panel 12 in the second direction is the longer side, and the side of the second panel 12 in the first direction is the shorter side.

[0077] like Figure 11 As shown, the first hollow sub-plate 31 in the top module unit includes multiple top reinforcing members 114, which are distributed in a crisscross pattern. The intersection of two crisscrossing top reinforcing members 114 is connected to one end of a first reinforcing member 111. The multiple first reinforcing members 111 on the first hollow sub-plate 31 in the top module unit are arranged at intervals.

[0078] Specifically, among the multiple top reinforcements 114, some of the top reinforcements 114 extend along a first direction, and some of the top reinforcements 114 extend along a second direction.

[0079] Furthermore, in the direction from the center to the edge of the core material board 15, the spacing between two adjacent top reinforcing members 114 gradually increases. For example, the dimensions of the first hollow sub-board 31 in the top module unit are 2100mm*800mm*100mm. The spacing between the two top reinforcing members 114 near the center of the core material board 15 can be 250mm to 300mm, and the spacing between the two top reinforcing members 114 far from the center of the core material board 15 can be 350mm to 400mm. The differentiated spacing of the top reinforcing members 114 in different areas can reduce the amount of material used.

[0080] Furthermore, in the first panel 11 and the second panel 12 of the first hollow sub-board 31 in the top module unit, the first panel 11 is located between the second panel 12 and the first hollow sub-board 31 in the bottom module unit, and the first panel 11 is located below the second panel 12. The thickness of the first panel 11 is greater than the thickness of the second panel 12. For example, the thickness of the first panel 11 can be 3.5 to 4.5 mm, and the thickness of the second panel 12 can be 2 mm to 3 mm.

[0081] Furthermore, the thickness of the first panel 11 gradually decreases from the center to the edge, with the thickness of the first panel 11 in the central region being greater than that in the edge regions. For example, the thickness of the first panel 11 at the center is 4.5 mm, and the thickness of the first panel 11 at the edge is 3.5 mm. The thickness of the same panel can also vary in different regions according to the stress characteristics; the panel thickness can be relatively thicker in the central region where deformation is greater, and relatively thinner in the surrounding areas near the edges.

[0082] Furthermore, the surface of the first panel 11 away from the second panel 12 is flat, and the surface of the first panel 11 close to the second panel 12 protrudes towards the second panel 12, forming a convex arc surface.

[0083] like Figure 12As shown in the embodiment of the present invention, the first hollow sub-plate 31 in the bottom module unit includes a plurality of bottom reinforcing members 115. The two ends of the bottom reinforcing members 115 are respectively connected to one end of two adjacent first reinforcing members 111, and six bottom reinforcing members 115 are connected end to end to form a hexagonal frame.

[0084] Specifically, every six bottom reinforcing members 115 are connected end to end to form a regular hexagonal frame.

[0085] It should be noted that the first hollow sub-board 31 in the top module unit and the first hollow sub-board 31 in the bottom module unit both include a core material board 15, a first panel 11, a second panel 12, two first side panels 13, two second side panels 14, a first reinforcing member 111, and a second reinforcing member 112.

[0086] The only differences between the first hollow sub-plate 31 in the top module unit and the first hollow sub-plate 31 in the bottom module unit are the layout of the multiple top reinforcing members 114, the layout of the multiple bottom reinforcing members 115, the layout of the multiple side reinforcing members 116, the layout of the multiple first reinforcing members 111, and the thickness of the first panel 11 and the second panel 12.

[0087] Furthermore, the present invention also provides a method for preparing a first hollow sub-plate, such as... Figure 13 As shown, the preparation method of the first hollow sub-plate includes: 301. Prepare the core material board, lay porous reinforcing material on the surface of the core material board to cover the core material board, and place the covered core material board on the processing board.

[0088] The core material board has multiple spaced through holes.

[0089] In one specific embodiment, through-holes extend from one side of the core material board to the other side surface of the core material board. Multiple through-holes are spaced apart in the core material board.

[0090] In one specific embodiment, a foam core material with a density of 0.1 g / cm³ is selected as the core material board, and through holes are opened inside the core material board according to design requirements. The surface of the core material board and the inner wall of the through holes are wiped with anhydrous ethanol to remove impurities, and then placed in a drying oven at 60 degrees Celsius for 2 hours. After being removed, it is cooled to room temperature for use.

[0091] In this embodiment of the invention, the porous reinforcing material is glass fiber. Glass fiber is a fibrous material made from glass as raw material through processes such as high-temperature melting, drawing, spinning, and weaving. The porous reinforcing material contains multiple interconnected pores, allowing liquid to flow into the interior of the porous reinforcing material and fill it.

[0092] In this embodiment of the invention, porous reinforcing material is laid in the through holes of the core material board, and porous reinforcing material is laid on the surface of the core material board to cover the core material board, and the covered core material board is placed on the processing board.

[0093] In one specific implementation, the through-holes in the core material board are filled with flocculent glass fibers. Specifically, glass fiber yarn is laid inside the through-holes of the core material board, and the glass fiber yarn is tightly adhered to the inner wall of the through-hole to ensure no gaps.

[0094] In one specific embodiment, layers of glass fiber are laid on a processing board. Specifically, a layered glass fiber cloth is obtained, and multiple layers of glass fiber cloth are laid on the processing board. A core board is placed on the multiple layers of glass fiber cloth on the processing board, and multiple layers of glass fiber cloth are laid on the upper and side surfaces of the core board.

[0095] Furthermore, a resin mixture is coated between adjacent layers of fiberglass cloth. The resin mixture further ensures that the fiberglass cloth is impregnated with the resin mixture.

[0096] Furthermore, the porous reinforcing material laid on the surface of the core material board is an integral material. Specifically, multiple layers of pre-cut planar fiberglass cloth are obtained, folded to form a hollow cuboid, and then multiple layers of pre-cut planar fiberglass cloth are laid on a processing board. The core material board is placed on the planar fiberglass cloth on the processing board, and the pre-cut planar fiberglass cloth is folded to cover the upper and side surfaces of the core material board, thereby completely covering the core material board. By covering the core material board with an integrally formed fiberglass cloth, the strength of the fiberglass cloth can be improved.

[0097] Furthermore, placing the covered core material board onto the processing board includes: laying an insulating layer on the processing board; and placing the covered core material board onto the insulating layer on the processing board. Specifically, the processing board is laid flat, and an insulating layer is laid on the processing board.

[0098] The isolation layer consists of resin, color masterbatch, and release agent.

[0099] Furthermore, laying an isolation layer on the processing board includes: cleaning the surface of the processing board and then laying an isolation layer on the processing board.

[0100] In this embodiment of the invention, the processing plate can be a steel plate. The surface of the processing plate is treated with sandblasting to remove rust, followed by soaking in an alkaline degreasing agent for 10 minutes, rinsing thoroughly with clean water, and drying to complete the cleaning process. After cleaning, a vinyl ester resin-based release layer is evenly sprayed onto the upper surface of the steel plate, avoiding the formation of air bubbles during the spraying process. For example, the release layer thickness is 0.3 mm.

[0101] Furthermore, one side surface of the pre-cut planar fiberglass cloth is provided with multiple strip-shaped fiberglass cloths, which are integrally formed with the planar fiberglass cloth, each strip corresponding to a through hole. Multiple layers of pre-cut planar fiberglass are laid on a processing plate, and the core material board is placed on the fiberglass cloth on the processing plate. The multiple strip-shaped fiberglass cloths are then passed through the through holes. The pre-cut planar fiberglass cloth is folded to cover the upper and side surfaces of the core material board, and one end of each strip-shaped fiberglass cloth is bonded to the planar fiberglass cloth. This completely covers the core material board, forming a single unit with the strip-shaped fiberglass cloths. By integrally molding the fiberglass cloth to cover the core material board, the strength of the fiberglass cloth can be improved.

[0102] 302. A flexible film layer is used to cover the core material board, and the flexible film layer and the processed board form a sealed space.

[0103] In this embodiment of the invention, the material of the flexible membrane layer can be ETFE (ethylene-tetrafluoroethylene copolymer membrane).

[0104] 303. Inject the resin mixture into the sealed space so that the resin mixture impregnates the core board and enters the pores in the porous reinforcing material.

[0105] Resin mixtures include resins.

[0106] Specifically, a vacuum is applied to the sealed space, and a resin mixture is injected into the sealed space so that the resin mixture impregnates the core material board and enters the pores in the porous reinforcing material.

[0107] More specifically, a resin mixture is injected into one end of the sealed space, while a vacuum is drawn from the other end of the sealed space, so that the resin mixture can immerse the core material board and enter the pores in the porous reinforcing material, which facilitates the better entry of the fluid resin into the porous reinforcing material.

[0108] In this embodiment of the invention, a vacuum treatment is performed on the sealed space, and a resin mixture is injected into the sealed space so that the resin mixture impregnates the core material board and enters the pores in the porous reinforcing material, including: (1) Vacuum the sealed space until the air pressure in the sealed space reaches the preset air pressure value.

[0109] Specifically, the sealed space is evacuated until the air pressure in the sealed space reaches the preset air pressure value, and the evacuation process continues for a preset time. This ensures that the gas is completely squeezed out.

[0110] The preset air pressure value is less than 0. Specifically, the preset air pressure value is between -0.05 MPa and -0.1 MPa. For example, the preset air pressure value is -0.08 kPa, and the preset duration is 30 minutes.

[0111] (2) Lift one side of the processing plate so that the processing plate is at a preset angle with the horizontal plane, evacuate the sealed space, and inject the resin mixture into the sealed space.

[0112] The preset angle can be between 30 and 60 degrees. For example, the preset angle is 45 degrees. You can set it according to the specific situation.

[0113] 304. The sealed space is cured to obtain the first fiberglass component.

[0114] In this embodiment of the invention, the temperature of the enclosed space is adjusted to a preset temperature and then cured. The preset temperature is between 40 and 60 degrees Celsius. For example, the preset temperature is 50 degrees Celsius.

[0115] 305. Remove the first fiberglass component and perform post-processing to obtain the second fiberglass component.

[0116] Specifically, the flexible membrane layer is removed, the first fiberglass component is taken out and cut to a preset size to obtain the second fiberglass component.

[0117] The second fiberglass component includes a core board and a reinforcing layer that wraps the core board. The reinforcing layer includes a porous reinforcing material and a resin mixture cured inside the porous reinforcing material. The reinforcing layer fills through holes and includes a first panel, a second panel, and two first side panels. The first panel and the second panel are arranged opposite to each other. The first panel and the second panel clamp the core board from both sides, and the two first side panels clamp the core board from both sides.

[0118] This invention utilizes a composite structure design of a core material, two layers of porous reinforcing materials, and a steel plate to create a double-layer lightweight structure, significantly improving the structural strength of the component under conditions of limited unit weight. The core material not only ensures the lightweight requirement but also forms a continuous reinforcement system with the porous reinforcing materials in the through-holes, effectively enhancing the overall integrity of the component and avoiding the problem of interlayer delamination in traditional multi-layer components.

[0119] 306. Drill holes in the second fiberglass component to obtain the first hollow sub-board.

[0120] The beneficial effects of this invention are as follows: Adaptable to operations inside existing buildings, solving key access challenges: Adopting a small-size, modular design, individual components can easily pass through conventional passages such as doors, windows, and corridors in existing buildings without damaging walls or enlarging doors and windows; individual components can be manually transported, avoiding damage to the building's internal environment caused by large equipment, filling the technological gap in pressurization operations inside existing buildings.

[0121] Lightweight design adapts to floor load-bearing capacity and ensures high safety: Made of fiberglass and lightweight hollow sandwich structure, the overall weight is reduced compared to traditional metal pressurized chambers, avoiding the risk of floor structure damage due to excessive weight. Suitable for old residential buildings, hotels and other scenarios with limited floor load-bearing capacity.

[0122] Compared to steel, fiberglass has a lower modulus of elasticity, poorer stiffness, and greater deformation under pressure. This application adopts a double-layer fiberglass panel reinforcement design, which significantly enhances the stiffness of the fiberglass module at the cost of a small increase in weight, thus solving the problem of large deformation under pressure.

[0123] Easy and efficient assembly, reducing construction costs: No large hoisting equipment or professional construction team is required; all operations can be completed manually, reducing labor and equipment costs; the disassembly process is simple and quick, and the site can be cleaned up quickly after the operation is completed.

[0124] Flexible and adaptable to diverse spaces, with strong versatility: It can flexibly combine different numbers of standard modules according to the existing building interior space dimensions to adapt to diverse space needs such as residential bedrooms, hotel rooms, and office buildings.

[0125] High reusability and excellent economic efficiency: The disassembled components are structurally stable and not easily damaged during disassembly and assembly. They can be reused in multiple existing building projects, reducing equipment investment costs; the fiberglass material has strong corrosion resistance and low maintenance costs.

[0126] It has minimal impact on existing buildings and is environmentally friendly: the assembly and disassembly process does not require damage to the building structure and does not generate pollutants such as dust and noise.

[0127] Compared to related technologies, the pressurized chamber includes two opposing first module units, two opposing second module units, two opposing third module units, and multiple first fasteners. Each of the first, second, and third module units has a handhole and a corresponding connecting hole, which are interconnected. The first, second, and third module units are connected via the connecting holes, and the handholes allow the first fasteners to pass through. This invention utilizes the interlocking handholes and connecting holes on the modular modules. The handholes facilitate the insertion of the first fasteners into the module unit, and the connecting holes allow for easy locking, enabling rapid assembly of the modules to form the pressurized chamber and improving installation efficiency.
