[0036] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0037] like Figure 1-Figure 8 As shown, a sealed pressure-bearing plate of this embodiment includes a support frame 10 , a foam support member 20 and a skin 30 .

[0038] The support frame 10 includes a plurality of staggered support rods, and the plurality of support rods surround a plurality of filling grids 10a. The staggered arrangement direction is not limited, for example, a plurality of support rods may be staggered to surround a rectangular filling grid 10a.

[0039] The foam support member 20 is disposed in each of the filling cells 10a to form an assembly with the support frame 10. That is, a foam support member 20 may be disposed in each of the filling cells 10a. The foam support member 20 and the support frame 10 form an assembly.

[0040] The skin 30 is wrapped around the outside of the assembly to seal the assembly and prevent air leakage in a high-pressure or low-pressure environment.

[0041] By setting a support frame 10, setting a foam support member 20 in the filling grid 10a of the support frame 10, forming an assembly, and covering the assembly with a skin 30, a sealed pressure plate is obtained. The setting of the foam support member 20 greatly reduces the weight of the sealed pressure plate. At the same time, the support frame 10 can provide a large pressure-bearing strength to the sealed pressure plate. The skin 30 can keep the sealed pressure plate sealed under pressure. The surface finish of the skin 30 structure is high and more beautiful. After testing, the sealed pressure plate can reduce the weight by more than 30% compared with a pure steel structure. And the amount of welding is small, which reduces the workload of the original welding sealing test. In this way, the use requirements of the oxygen chamber are met, and at the same time, the disassembly and assembly of the oxygen chamber is convenient, and the difficulty of transforming the existing house into an oxygen chamber is reduced, which is conducive to the modular design of the micro-hyperbaric oxygen chamber.

[0042] The skin 30 is composed of fiber cloth, fiber felt and resin, wherein the fiber is glass fiber, carbon fiber, basalt fiber, and the resin can be flame retardant or high strength. The assembly is wrapped by the skin 30 so that the entire sealing pressure plate has the ability to seal, and the wrapping method is resin transfer molding (RTM).

[0043] In some embodiments, the foam support member 20 includes a foam body 21 and a support strip 22. The foam body 21 has a plurality of through holes 21a that pass through the top and bottom surfaces thereof. The support strip 22 is disposed in the through holes 21a and connected to the skin 30. The compressive strength of the material of the support strip 22 is greater than the compressive strength of the material of the foam body 21.

[0044] The foam body 21 is a foaming material. In some embodiments, the foam body 21 is a PVT rigid foam or a PET rigid foam.

[0045] The material of the support bar 22 is not limited. In some embodiments, the support bar 22 is made of resin. The resin may be epoxy resin.

[0046] It is understandable that, since the skin 30 is wrapped around the outside of the assembly, the skin 30 is supported by the foam support 20. The support strip 22 in the foam body 21 is connected to the skin 30, and the compressive strength of the support strip 22 material is greater than the compressive strength of the foam body 21 material, so that the overall support capacity of the foam support 20 is improved, so that it is better suitable for pressure environments. In addition, the plurality of through holes 21a enables it to have multiple support strips 22, further improving the strength of the sealed pressure plate. The resin is also lighter than other fillers, which can achieve the purpose of weight reduction.

[0047] In some embodiments, the skin 30 includes a fiber layer and a resin layer, the limiting layer has a gap inside, and the resin layer is coated on the fiber layer and filled in the gap, so that the skin 30 has a certain degree of compression resistance.

[0048] In some embodiments, the fiber layer includes a plurality of fiber cloths spliced ​​together, and the edges of adjacent fiber cloths overlap. It is understood that the fiber cloths can be provided in multiple layers.

[0049] In some embodiments, the fiber layer includes a plurality of fiber cloths spliced ​​together and a plurality of fiber felts spliced ​​together, and the fiber cloths and the limiting felts are stacked.

[0050] In some embodiments, the resin layer is integrally formed with the support bar 22. That is, the resin layer and the support bar are made of the same material and are formed at the same time, so that the overall compression resistance is stronger.

[0051] In some embodiments, the skin 30 includes an upper skin layer 31 covering the upper surface of the assembly and a lower skin layer 32 covering the lower surface of the assembly, and the support bar 22 extends out of the through hole 21a to connect between the upper skin layer 31 and the lower skin layer 32. In this way, the support bar 22 can transfer the pressure of the upper skin layer 31 to the lower skin layer 32, so that the upper skin layer 31 and the lower skin layer 32 bear the pressure together, thereby improving the pressure bearing capacity.

[0052] In some embodiments, the sealing pressure plate includes a structural adhesive layer, which is disposed on the surface of the support frame 10 , and is used to connect the support frame 10 and the foam support member 20 , and to connect the support frame 10 and the skin 30 .

[0053] The structural adhesive layer is preferably a highly elastic structural adhesive, which is conducive to deformation buffering. The structural adhesive layer can be an epoxy structural adhesive. In some embodiments, the structural adhesive layer is an acrylate epoxy structural adhesive.

[0054] The foam support member 20 is bonded to the support frame 10 through the structural adhesive layer, so that the assembly structure is stable and the subsequent molding of the fiber layer can be facilitated.

[0055] It is understandable that when the support frame 10 is made of metal material such as steel, its bonding with the resin material is poor. By providing a structural adhesive layer, the reliability of the connection between the support frame 10 and the skin 30 can be improved.

[0056] In some embodiments, the support rod includes a rectangular metal tube 11 , an angle steel bar 12 , and a metal sheet bar 13 .

[0057] The rectangular metal tubes 11 are arranged in parallel or vertically crosswise. The angle steel bars 12 are arranged around the rectangular metal tubes 11. The metal strips 13 are connected between adjacent rectangular metal tubes 11 or between the angle steel bars 12 and the rectangular metal tubes 11. The rectangular metal tubes 11, the angle steel bars 12 and the metal strips 13 together enclose a plurality of filling grids 10a.

[0058] The rectangular metal tube 11 is a hollow tube with a rectangular structure. The angle steel bar 12 is an L-shaped steel bar structure. The rectangular metal tube 11, the angle steel bar 12 and the metal sheet strip 13 can be connected by welding.

[0059] The shape of the filling cell 10a may be a rectangle.

[0060] In some embodiments, part of the support rods surround the window 10b, and an opening 30b matching the window 10b is formed on the skin 30. Glass can be provided at the opening 30b and the window 10b to form an observation window or as an entrance for electrical components.

[0061] In some embodiments, a plurality of waist-shaped holes are provided on the support frame 10 and the edge of the skin 30. It is understood that when a plurality of sealing pressure-bearing plates are matched, fasteners can be connected to the waist-shaped holes of adjacent sealing pressure-bearing plates to achieve assembly.

[0062] In some embodiments, the support frame 10 further includes a lifting eye 14, which is used to provide a lifting device installation position, and the lifting eye 14 is welded to the support frame 10; the skin 30 is provided with a through hole 30a corresponding to the lifting eye 14. When lifting, the lifting device is connected to the lifting eye 14, thereby lifting the entire sealing pressure plate.

[0063] In order to improve the reliability of the connection of the lifting eye 14 , in some embodiments, the lifting eye 14 is welded to the rectangular metal tube 11 .

[0064] In some embodiments, the lifting eye 14 has a threaded hole for connecting with a lifting tool. In other words, the lifting tool has a threaded structure and can be threadedly connected in the threaded hole, thereby facilitating lifting.

[0065] In some embodiments, the steps of preparing the sealed pressure plate include:

[0066] A. Cut the materials according to the outer dimensions of the sealed pressure plate, and then assemble and weld the angle steel bar 12, rectangular metal tube 11, metal sheet strip 13, and eye 14 on the platform. Weld according to the welding quality assurance requirements to ensure the flatness of the support frame 10. After welding, remove the rust from the support frame 10 and polish it with an iron brush. After polishing, it is easier for the structural adhesive to embed into the surface layer of the steel frame to form an anchor point, which is conducive to a firm connection.

[0067] B. On the workbench, select a highly elastic structural adhesive and apply it to the support frame 10 on the contact surface with the foam to form a structural adhesive layer. The foam body 21 penetrates the through hole 21a of 3-5mm, and then fills it into the filling grid 10a of the support frame 10, waiting for the foam body 21 and the support frame 10 to be bonded by the structural adhesive.

[0068] C. Open an RTM mold according to the size of the pressure-bearing sealing plate, apply a release agent on the mold surface, put fiber cloth into the mold, apply structural adhesive to the surface of the support frame 10 again, and stick 1 to 2 layers of fiber cloth on the surface of the structural adhesive, and then hoist the assembly into the mold covered with fiber cloth.

[0069] D. Spread the fiber cloth again to cover the assembly, with a distance of 80-140mm between the overlapped parts of the fiber cloth. Then place the demoulding cloth, guide tube, mesh cloth, RTM bag film, resin extraction tube, and sealant sealing bag film. Then, introduce the resin through the RTM process. The resin infiltrates the fiber cloth in the mold and passes through the pinholes in the 20 foam. Then, the resin is cured to obtain an integrated product.

[0070] E. Demoulding: remove unnecessary demoulding cloth, guide tube, mesh cloth, RTM bag film, resin extraction tube and sealant.

[0071] The embodiment of the present application also provides an oxygen cabin, including a plurality of sealed pressure plates, which can be spliced ​​with each other.
