[0003] At present, pressurized building complexes can be divided into two types according to the expansion and installation form: overall modular hoisting and on-site structural assembly. Compared with the traditional construction form, by completing some modules in the factory, the workload of on-site production and installation is reduced, and it has the characteristics of short construction period, low cost and small environmental impact.

[0004] However, the enclosed spaces of existing pressurized building complexes are all relatively fixed structural forms. For the structural form of pressurized enclosed variable space, it is necessary to combine and expand the space according to actual needs. When applying, the installation accuracy and enclosed structure design should be comprehensively considered to ensure the overall splicing quality and airtight performance. If the expansion connection form of the existing pressurized fixed space is still used, the following problems will exist:

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or implementations in a suitable manner.

[0055] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0056] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.

[0057] At present, the pressurized building complex can be divided into two types according to the expansion installation form: overall modular hoisting and on-site structural assembly, among which:

[0058] The overall modular lifting form is aimed at a building complex composed of single-cabin modules. First, multiple single-cabin modules are prefabricated in the factory. The single-cabin modules have independent pressurization and oxygen supply functions. After being transported to the target site, the multiple single-cabin modules are simply spliced ​​and fixed, and necessary decoration is carried out to form the final pressurized activity space.

[0059] The on-site structural assembly form is aimed at integral pressure-bearing building complexes. It uses building frames, wall panels and other components as basic units. After prefabrication in the factory, they are transported to the target site and then spliced ​​and assembled on site in a more complex manner to form an integral pressure-bearing exterior wall. The internal structure is a non-pressure-bearing design, ultimately forming a large-volume pressurized activity space.

[0060] The expansion installation form of the existing building complex reduces the workload of on-site production and installation by completing some modules in the factory. It has the characteristics of short construction period, low cost and small environmental impact.

[0061] However, the structural form of the pressurized enclosed variable space needs to be combined according to actual needs. When applied, not only the installation accuracy and the closed structure design must be considered comprehensively, but also the overall splicing quality and sealing performance must be guaranteed.

[0062] For the structural form of pressurized enclosed variable space, the above-mentioned traditional installation method is adopted. Although it can form a large pressurized space, the overall airtightness of the pressure-bearing wall is poor and continuous pressurization is required; in addition, more manpower and time are required for on-site construction, and the construction quality is easily affected by the environment and personnel technology.

[0063] To solve the above technical problems, please refer to Figure 1-7 As shown, an embodiment of the present invention provides an expansion connection system suitable for pressurized closed variable space, the expansion connection system includes multiple single cabin modules 1, a plurality of connection mechanisms 2 and a plurality of sealing mechanisms 3, wherein:

[0064] A plurality of single-cabin modules 1 are horizontally parallel and juxtaposed to form an overall pressurized closed space, and each single-cabin module 1 includes a pressurized space structure 11 and a pressure-changing space structure 12 which are horizontally parallel and spliced ​​together, and a pressure-bearing airtight door 13 is provided between the pressurized space structure 11 and the pressure-changing space structure 12, and a first door opening 111 which is arranged opposite to each other is provided on the side where two adjacent pressurized space structures 11 are close to each other, and a second door opening 121 which is arranged opposite to each other is provided on the side where two adjacent pressure-changing space structures 12 are close to each other.

[0065] The connecting mechanism 2 is fixedly connected between the corresponding connecting nodes of any two adjacent single-cabin modules 1; the sealing mechanism 3 is embedded on both sides of the second door opening 121 of the pressure-changing space structure 12, and the middle of the sealing mechanism 3 is suitable for installing a sealing door 14, and the sealing door 14 is suitable for performing pressure-bearing transformation on the pressure-changing space structure 12.

[0066] Specifically in the embodiment of the present invention, in order to achieve the expansion of the pressurized enclosed space, multiple single cabin modules 1 are horizontally parallel and spliced ​​to form an overall pressurized enclosed space. Each single cabin module 1 includes a pressurized space structure 11 and a pressure-changing space structure 12. The pressure-bearing airtight door 13 is opened between the pressurized space structure 11 and the pressure-changing space structure 12 to separate and connect the two spaces. The first door opening 111 and the second door opening 121 are respectively opened on the side where two adjacent pressurized space structures 11 and pressure-changing space structures 12 are close to each other, and are used to connect adjacent modules to form a continuous pressurized enclosed space. The connecting mechanism 2 is fixedly connected between the corresponding cabin connection nodes of the two adjacent single cabin modules 1 to ensure the stability and strength of the structure; the sealing mechanism 3 is embedded on both sides of the second door opening 121 of the pressure-changing space structure 12, and a sealing door 14 is installed in the middle to transform the pressure-bearing space structure 12.

[0067] Therefore, the design of the connection mechanism 2 and the sealing mechanism 3 ensures the structural stability and airtightness between the modules, allowing space expansion while maintaining pressure and environmental control, which can not only meet the various combinations of variable spaces, but also ensure the overall airtight performance, while also improving the convenience of on-site assembly operations, improving the flexibility and efficiency of space use, and ensuring safety and reliability under different pressure and environmental conditions. Through the design of pressure-bearing airtight doors and sealing doors, precise control of pressure and environment can be achieved while maintaining the overall structural stability.

[0068] By adopting the above installation method, a large pressure-bearing space can be formed, while the overall sealing performance of the pressure-bearing wall can be significantly improved, and the manpower and time required for on-site construction can be reduced, and the construction quality is significantly improved.

[0069] For further information, see Figure 1 As shown, the first door opening 111 is suitable for installing the sealing mechanism 3 so that each pressurized space structure 11 forms an independent closed space. Through the installation of the sealing mechanism 3, each pressurized space structure 11 can form a relatively independent closed space, which can be used independently of each other in terms of space and function.

[0070] For further information, see Figure 1 As shown, the sealed door 14 is a pressure-bearing structure or a non-pressure-bearing structure. Specifically in the embodiment of the present invention, when the sealed door 14 is a pressure-bearing structure, the variable pressure space structure 12 is suitable for an environment with a higher internal pressure, so as to expand the internal space of each single cabin module 1, which is convenient for people in high-altitude areas to use and meet the living comfort environment; when the sealed door 14 is a non-pressure-bearing structure, the variable pressure space structure 12 can be used as a public corridor without being subjected to a high-pressure environment.

[0071] For further information, see Figure 3 As shown, multiple single-cabin modules 1 are suitable for being spliced ​​and layered in the horizontal and vertical directions respectively through a connecting mechanism 2 to form an overall pressurized closed space of more than two layers. This modular design allows the structure to be expanded as needed to form a larger closed space. The connecting mechanism 2 is the key to achieving the connection between the single-cabin modules 1. The connecting mechanism 2 needs to have sufficient strength and sealing to ensure that the closed space formed after splicing can withstand internal pressurization to ensure that no leakage occurs at the connection under pressure. After the overall pressurized closed space is formed, gas is injected into the interior through the pressurization system to increase the internal pressure, and the pressure is precisely controlled to maintain the stability and safety of the pressurized closed space.

[0072] Therefore, the overall pressurized closed space formed by the single cabin module 1 and the connecting mechanism 2 can achieve flexible space expansion, structural strength assurance, sealing performance maintenance and precise pressure control; through modular splicing, the space size can be flexibly increased according to needs, thereby improving space utilization and adaptability.

[0073] For further information, see Figure 4 As shown, the connection mechanism 2 includes a connector 21 and a connection plate 22 , wherein the connection plate 22 is provided with a groove, and the lower part of the connector 21 is suitable for being inserted into the groove of the connection plate 22 .

[0074] Specifically in the embodiment of the present invention, the connection mechanism 2 is composed of a connector 21 and a connection plate 22. This arrangement of the connection mechanism 2 allows the single cabin module 1 to be quickly spliced ​​and layered in the horizontal and vertical directions. The lower part of the connector 21 is inserted into the pre-processed groove on the connection plate 22, and the connection is fixed by welding at the edge, which provides additional strength and stability to ensure that the connection will not loosen in a pressurized environment.

[0075] Therefore, the design of the connecting mechanism 2 provides a stable, high-strength, and highly adaptable connection method, which is suitable for forming an integral pressurized closed space of more than two layers, especially in applications requiring rapid splicing and high sealing.

[0076] Preferably, in this embodiment, two connectors 21 are correspondingly installed on each connecting plate 22 , and the two connectors 21 correspond to the cabin connection parts of two single cabin modules 1 .

[0077] Of course, in some other embodiments, due to the different external structural shapes of the single cabin module 1, the corresponding cabin connection nodes will also change accordingly, so the number and position of the connectors 21 can be adaptively adjusted according to the number and position of the cabin connection nodes.

[0078] For further information, see Figure 4 , 5 As shown, the connector 21 includes a base 211, an adjustment block 212, an eccentric pin 213 and a fastening screw 214, wherein:

[0079] The base 211, the adjustment block 212 and the eccentric pin 213 are connected in sequence, and the fastening screw 214 is vertically connected between the adjustment block 212 and the eccentric pin 213; the base 211 serves as the basic part of the connector 21, and the center of the base 211 in this embodiment is provided with a threaded inner hole 2111 and a vent hole 2112 that are connected through and through; the adjustment block 212 is connected to the base 211, and in this embodiment, the adjustment block 212 includes a first polygonal boss 2121 and an outer stud 2122 that are coaxially connected as one piece, and the outer stud 2122 is suitable for being threadedly connected in the threaded inner hole 2111, so that the end face of the first polygonal boss 2121 abuts against the end face of the base 211, thereby realizing the fixation and adjustment between the adjustment block 212 and the base 211, and a coaxial cylindrical groove 21211 is provided on the side of the first polygonal boss 2121 away from the outer stud 2122.

[0080] The eccentric pin 213 is used to connect with the adjustment block 212. In this embodiment, the eccentric pin 213 includes a cylindrical pin 2131, a second polygonal boss 2132 and a cylindrical boss 2133 connected in sequence, and the second polygonal boss 2132 is coaxially connected with the cylindrical boss 2133 to ensure the stability and accuracy of the eccentric pin 213; the cylindrical pin 2131 and the second polygonal boss 2132 are eccentrically arranged to allow the eccentric pin 213 to adjust its position within a certain range to meet different connection requirements. The cylindrical boss 2133 is suitable for being inserted into the cylindrical groove 21211, and the cylindrical pin 2131 is suitable for being plugged into the connection node of the cabin column beam of the single cabin module 1; the fastening screw 214 is vertically connected between the adjustment block 212 and the eccentric pin 213, and is used to lock and fix the cylindrical boss 2133 in the first polygonal boss 2121.

[0081] Thus, the structure of the connector 21 provides a certain amount of adjustment space while maintaining structural strength to adapt to different installation environments and requirements. Through the eccentric setting of the eccentric pin 213, fine adjustment can be achieved to ensure accurate docking between the connector 21 and the cabin, and the fastening screw 214 is used for final fixation to ensure the stability of the connection.

[0082] For further information, see Figure 1 , 2 As shown in Figures 6 and 7, the sealing mechanism 3 is designed to adapt to connection conditions with different gap sizes. As a preferred embodiment of the present invention, the sealing mechanism 3 includes a first sealing mechanism 31 and a second sealing mechanism 32, and the first sealing mechanism 31 is suitable for connecting to the inner side of the joint of the two cabin columns and beams 15 when the gap between the two single cabin modules 1 is less than or equal to 3 mm, and the second sealing mechanism 32 is suitable for connecting to the inner side of the joint of the two cabin columns and beams 15 when the gap between the two single cabin modules 1 is greater than 3 mm.

[0083] Specifically, the first sealing mechanism 31 is suitable for the case where the gap is less than or equal to 3 mm, and the second sealing mechanism 32 is suitable for the case where the gap is greater than 3 mm. By selecting a suitable sealing mechanism 3, it can be ensured that the joints of the cabin column beam 15 can achieve a good sealing effect under different gap sizes to prevent gas leakage or intrusion of other external factors.

[0084] Thus, the sealing mechanism 3 can cope with gaps of different sizes due to its flexibility and adaptability, ensuring the sealing of the connection, especially under high pressure or special environmental conditions. Through this arrangement, the risk of sealing failure caused by gaps of different sizes can be reduced, and the reliability and safety of the entire system can be improved.

[0085] For further information, see Figure 6As shown, the first sealing mechanism 31 includes two first pressing plates 311, a first rubber plate 312, two first mounting frames 313 and a first sealing adhesive 314, wherein:

[0086] The first sealant 314 is suitable for being coated on the outside of the joint between two adjacent cabin column beams 15, one side of the two first mounting frames 313 is respectively welded to the inside of the joint between the two cabin column beams 15, the two first mounting frames 313 are connected on the sides close to each other by transverse bolts, and the first rubber plate 312 is provided on the surface of the two first mounting frames 313 facing away from the cabin column beam 15, and the first rubber plate 312 is correspondingly connected to the two first mounting frames 313 by two vertical bolts.

[0087] Specifically in the embodiment of the present invention, the two first pressure plates 311 are used to apply pressure to the first rubber sheet 312 to ensure the sealing effect; the two first mounting frames 313 are used as mounting structures and are fixed on the inner side of the joint of the cabin column beam 15 to ensure the stability of the mounting frames; the two first pressure plates 311 are installed in place, and the two first mounting frames 313 are connected by vertical bolts to apply pressure to the first rubber sheet 312 to ensure that the sealant is compacted to form an effective seal.

[0088] By combining welding, coating sealant, installing rubber plates and pressure plates and other structures, effective sealing of the joints of the cabin columns and beams 15 is achieved. This sealing method takes into account both the stability of the structure and the reliability of the seal, and is suitable for situations where the gaps are small, ensuring the airtightness and structural integrity of the cabin.

[0089] For further information, see Figure 7 As shown, the second sealing mechanism 32 includes two second pressing plates 321, a second rubber plate 322, two second mounting frames 323, a support plate 324, a metal corrugated plate 325, two sealing strips 326 and a heat insulation cotton 327, wherein:

[0090] The two second mounting frames 323 are respectively welded to the sides of the two cabin column beams 15 that are close to each other. The inner sides of the two second mounting frames 323 are sealed by the second rubber plate 322, the two second pressure plates 321 and the two vertical bolts. The metal corrugated plate 325 is correspondingly sealed to the outer sides of the two second mounting frames 323 by two sealing strips 326 and two vertical bolts. The support plate 324 is suitable for supporting between the two cabin column beams 15, and the space between the support plate 324 and the metal corrugated plate 325 is suitable for filling with thermal insulation cotton 327.

[0091] Specifically in the embodiment of the present invention, the second sealing mechanism 32 is suitable for the case where the gap between the two single cabin modules 1 is greater than 3mm.

[0093] The embodiment of the present invention further provides a method for installing the above-mentioned expansion connection system suitable for pressurized closed variable space, and the installation method comprises the following steps:

[0094] Step S 100 : Determine the splicing form of the single cabin module 1 according to the layout of the pressurized closed variable space.

[0095] In this step, according to the specific layout and requirements of the pressurized enclosed variable space, it is determined how to splice the single cabin module 1 to meet the functional and structural requirements of the space and ensure that the single cabin module 1 can be effectively spliced ​​according to the predetermined design and functional requirements.

[0096] Step S 200 : According to the connection nodes of the cabin column beam 15, the structure of the connecting plate 22 and the number of connectors 21 are determined. After the connecting plate 22 and the connector 21 are welded, they are assembled with the cabin.

[0097] In this step, the structure of the connecting plate 22 is designed according to the connection nodes of the cabin column beams 15, and the number of connectors 21 required is determined to ensure a stable connection between the cabins and to ensure the strength and reliability of the cabin connection.

[0098] Step S 300: Adjust the height of the adjustment block 212 and the position of the eccentric pin 213 on the connector 21 to adjust the relative position and height of the cabin. After the adjustment is completed, lock the connector 21 by tightening the screws 214 to fix the position of the cabin.

[0099] In this step, the relative position and height of the cabin can be fine-tuned to meet different installation requirements by adjusting the height of the adjustment block 212 and the position of the eccentric pin 213 on the connector 21. After the adjustment is completed, the connector 21 is locked by tightening the screws 214 to ensure the fixed position of the cabin and the stability of the structure.

[0100] Step S 400 : After the position of the cabin is adjusted and fixed, the inner side of the cabin connection is sealed by the sealing mechanism 3;

[0101] In this step, the sealing mechanism 3 is used to seal the inner side of the cabin connection to prevent gas leakage and intrusion of other external factors, ensure the airtightness and environmental control inside the cabin, and maintain the integrity of the pressurized enclosed space.

[0102] Step S 500 : Seal the outside of the cabin connection by applying sealant.

[0103] In this step, sealant is applied to the outside of the cabin connection to form an additional sealing layer, which enhances the sealing effect of the cabin connection and provides an additional protective layer to prevent sealing failure due to environmental changes or mechanical stress, thereby enhancing the durability and reliability of the cabin.

[0104] In general, the installation method of the expansion connection system for pressurized enclosed variable space in the embodiment of the present invention ensures the functionality and safety of the expansion connection system for pressurized enclosed variable space through precise structural design, careful adjustment, stable connection and multi-layer sealing. This method not only improves the strength and reliability of the cabin connection, but also ensures the airtightness and environmental control of the cabin through multi-layer sealing technology, and is suitable for pressurized enclosed spaces that require high airtightness and environmental control.

[0105] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
