[0037] The features and performance of this application will be further described in detail below with reference to the embodiments.
[0038] Example 1
[0039] This embodiment discloses a combined structure pressurized airtight chamber, including a frame, a combined panel 2, and a perforated frame 5; wherein: the frame is assembled from combined columns 1 and combined beams 2, the exterior of the combined columns 1 is a rigid pipe 11 and the interior is filled with concrete 12, the exterior of the combined beams 2 is a rigid pipe 21 and the interior is filled with concrete 22, and adjacent rigid pipes (11, 21) are welded and sealed together, see Figure 1 and Figure 2The composite panel 3 is installed on each side of the frame to form a wall. The two outer sides of the composite panel 3 are rigid plates 31, and the interior is filled with concrete 32. Adjacent rigid plates 31 are welded and sealed to rigid pipes (11, 21). See Figures 1 to 3 The opening frame 5 is located at the opening 4 in the wall. The opening frame 5 is composed of vertical rigid members 51 and horizontal rigid members 52, which are welded and sealed together. The vertical rigid members 51 and horizontal rigid members 52 are also welded and sealed to the adjacent rigid plate 32. (See attached image.) Figure 1 and Figure 2 .
[0040] Regarding the combination panel 3, in this embodiment, preferably:
[0041] A single-sided wall is formed by splicing together a single composite panel 3 or multiple composite panels 3, which are then sealed and welded together using rigid plates 31. When the single-sided wall is small, a single composite panel 6 is sufficient; when the single-sided wall is wide, such as... Figure 5 As shown, multiple modular panels 3 are spliced together; considering construction and to facilitate hoisting, the weight of each modular panel 3 can be controlled within a certain range, therefore the size of each modular panel 3 is relatively small, such as... Figures 5 to 7 As shown, this requires splicing multiple combination panels 3 to form a single wall.
[0042] like Figures 3 to 7 As shown, the rigid plate 31 adopts a profiled structure with a stacked cross section. The profiled rigid plate 31 has a higher load-bearing capacity under the same projected area. It can be made by cold bending of flat plates, and its arrangement direction can be adjusted according to the usage requirements.
[0043] like Figure 4 As shown, the rigid plate 31 has reinforcements welded to its inner side to enhance the performance of the composite panel 3. The reinforcements are one or more of studs 33, transverse ribs 34 and longitudinal ribs 35. The studs 33 and transverse ribs 34 can enhance the connection performance between the rigid plate 31 and the concrete 32, and the longitudinal ribs 35 can enhance the mechanical properties of the composite panel 3. The three are selected according to the specific performance requirements.
[0044] To enhance the connection performance between the rigid plate 31 and the concrete 32, a texture can be distributed on the surface of the rigid plate 31, which can be one or more of the following: indentation, raised pattern, etc.
[0045] Regarding the framework, in this embodiment, preferably:
[0046] The rigid tubes (11, 21) are square tubes with rectangular cross-sections; the use of square tubes facilitates welding and splicing between the rigid tubes (11, 21) and between the rigid tubes (11, 21) and the rigid plate 31.
[0047] Regarding the hole frame 5, in this embodiment, preferably:
[0048] like Figure 8 and Figure 9 As shown, the two ends of the vertical rigid member 51 abut against the upper and lower rigid tubes 21 and are welded and sealed to the rigid tubes 21, while the two ends of the horizontal rigid member 52 abut against the left and right vertical rigid members 51 and are welded and sealed to each other. The force on the vertical rigid member 51 can be directly transmitted to the frame, which can prevent the window frame from damaging the combined panel 3 when the pressure-bearing airtight door or pressure-bearing airtight window installed on the opening frame 5 is too heavy.
[0049] The cross-section of the vertical rigid member 51 can be H-shaped, angular, or groove-shaped, which ensures that it can withstand a large load while reducing its own weight.
[0050] Regarding material selection, in this embodiment, the preferred materials are:
[0051] Rigid tubes (11, 21), rigid plates 31, vertical rigid components 51 and horizontal rigid components 52 can be made of steel, aluminum alloy or fiberglass. Among them, steel is the most reliable but the heaviest, while fiberglass is the lightest but has relatively poor load-bearing capacity.
[0052] From the above schemes, we can see that:
[0053] This cabin combines rigid and concrete structures. Compared with steel pressurized airtight cabins, the amount of rigid materials used in this cabin is significantly reduced, and the construction cost can be reduced by more than half. In addition, the concrete (12, 22, 32) inside the composite column 1, composite beam 2 and composite panel 3 improves the thermal insulation and sound insulation performance. Compared with concrete pressurized airtight cabins, this cabin reduces the amount of concrete used by more than half, greatly reduces its self-weight, and is easy to deploy. Furthermore, the rigid structure (11, 21, 31) on the outside of the composite column 1, composite beam 2 and composite panel 3 is used for welded and sealed connection to ensure airtightness.
[0054] In this cabin, the composite column 1, composite beam 2 and composite panel 3 are all made of external rigid material and filled with concrete. They have good mechanical properties and reliable force transmission. Furthermore, the composite column 1 and composite beam 2 form a frame and the composite panel 3 forms a wall, forming a load-bearing system, which makes the cabin have high load-bearing capacity.
[0055] In this cabin, the opening frame 5 provides installation positions for pressure-bearing airtight doors and pressure-bearing airtight windows. Furthermore, the welded and sealed connection between it and the adjacent rigid plate 31 ensures the airtightness of the opening 4 in the cabin.
[0056] In this cabin, concrete (12, 22) can be directly poured into the rigid tubes (11, 21) of the composite column 1 and composite beam 2. The rigid plate 31 of the composite panel 3 can be used as a template to pour the internal concrete 32. No on-site formwork is required, and the construction is simple.

The pressure-bearing airtight door can meet the needs of personnel entering and exiting the pressurized airtight chamber, and the pressure-bearing airtight window can meet the requirements of lighting.
[0059] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
