Description

Technical Field

[0001] The present invention relates to the technical field of pressurized buildings, and in particular to an assembled pressurized building with a variable space and a use method thereof. Background Art

[0002] A pressurized building is a building that uses equipment to pressurize the interior of the building, thereby creating an air pressure environment similar to that at different altitudes, to achieve the purpose of living or scientific research. Since there is a pressure difference between the interior and exterior of a pressurized building when it is in use, the entrances and exits of the building cannot be opened directly under the pressure difference environment, and the comfort environment needs of users in emergency situations cannot be guaranteed.

[0003] At present, domestic prefabricated buildings suitable for high-altitude areas and with pressurized oxygen supplementation functions are mostly seen in single fixed space buildings or multiple fixed space assemblies combined together to form prefabricated building complexes. However, for a single fixed space building, its internal functional space is basically immutable, and even the internal functional space may be occupied by objects such as integrated equipment, which further reduces the living space, making it impossible to expand the space according to actual needs or avoid occupying the actual living space; secondly, for prefabricated building complexes, most of them use bolt connections or welding methods, and the assembly construction efficiency has not been greatly improved. The types of connecting components are diverse, which is not conducive to installation and later maintenance and disassembly, and the production efficiency is low.

[0004] Finally, there is little research on prefabricated pressurized building systems with variable spaces. After domestic traditional pressurized buildings are built, their internal functional spaces are basically immutable, the shear walls are densely arranged, and they take up a large usable space. Summary of the invention

[0005] In view of this, the present invention provides a variable-space assembled pressurized building and a method of using the same, so as to effectively solve the technical problems that existing fixed-space buildings cannot expand their space according to actual needs and are difficult to assemble.

[0016] A lobby module is provided on a side of the staircase unit module close to the variable space unit, and the lobby module is connected to the staircase unit module;

[0017] The variable space unit is suitable for being expanded in the longitudinal direction through the stair unit module to form the multi-layer space structure.

[0040] The integrated equipment system is controlled and adjusted to reduce the pressure in the combined pressure transformation space to the same as that outside, and then the second airtight pressure-bearing door on the combined pressure transformation space is opened to leave the combined pressure transformation space normally.

[0041] Compared with the prior art, the present invention has significant advantages and beneficial effects, which are specifically embodied in the following aspects:

[0042] 1. The prefabricated pressurized building with variable space in the present invention is composed of variable space units, each of which is composed of an airtight pressure-bearing space and a combined pressure-changing space spliced ​​together, and the airtight pressure-bearing space and the combined pressure-changing space are both three-dimensional rectangular closed space structures surrounded by an airtight pressure-bearing structure, and the core of the airtight pressure-bearing structure lies in the pressure-bearing airtight layer. By arranging a fireproof layer and a thermal insulation layer inside and outside the pressure-bearing airtight layer to provide fireproof and thermal insulation functions, the airtight pressure-bearing structure is formed, which ensures the strength and airtightness of the structure and the airtightness of the variable space unit. While ensuring the airtightness, by adding a combined pressure-changing space, objects such as the integrated equipment system are pre-placed in the combined pressure-changing space, avoiding the space occupation of the airtight pressure-bearing space and increasing the space area of ​​the actual living environment in the airtight pressure-bearing space. The air intake and exhaust device is located on the airtight pressure-bearing space and is connected to the integrated equipment system to control and adjust the internal environmental parameters, such as air purification, fresh air in and out, etc. The integrated equipment system can adjust the airtight pressure-bearing space according to the set equivalent altitude, and enter the normal use state after reaching the set pressure, ensuring the stability and comfort of the internal environment; and the airtight pressure-bearing door is installed on the airtight pressure-bearing structure, which is used for the entry and exit of users on the one hand, and on the other hand to ensure the airtightness of the space when opening and closing. In this way, through the structural setting of the variable space unit, building components or modules can be prefabricated in the factory, and then assembled and installed on site, realizing a fast, efficient and repeatable construction process. This construction method has the advantages of low construction cost, low design difficulty, good process connection effect, energy saving and environmental protection, and can expand the space according to actual needs; through the adjustment of the integrated equipment system, the pressurized building can adapt to different environmental conditions, such as changes in altitude, enhance the adaptability and practicality of the building, and ensure the safety, comfort and flexibility of the variable space.

[0043] 2. The combined connection method of the combined pressure-transformation space can not only form a public corridor and realize an intermediate conversion channel for entering and exiting different airtight pressure spaces; the combined pressure-transformation space can also achieve a sealed connection through the installation of airtight doors and windows without occupying additional space, ensuring the sealing between the public corridor and the airtight pressure space, thereby making the airtight pressure space, the combined pressure-transformation space and the external environment present a transitional air pressure environment from high to low in turn.

[0044] 3. The combined transformer space can be switched to install airtight pressure-bearing door and window structures or non-airtight pressure-bearing door and window structures to facilitate the conversion between pressure-bearing and non-pressure-bearing. This allows the airtight and non-airtight structures to be quickly switched according to different usage requirements and environmental conditions to adapt to more different usage scenarios, thereby improving the adaptability and flexibility of the pressurized building. In addition, the switchable structural design simplifies the maintenance and operation procedures, making the management of the pressurized building more convenient while also reducing maintenance costs.

[0045] 4. The article transfer device is set between the airtight pressure-bearing space and the combined pressure-changing space, and is used to quickly transfer small articles between the airtight pressure-bearing space and the combined pressure-changing space when there is a pressure difference between indoors and outdoors. This device allows the safe transfer of articles without destroying the sealing of the airtight pressure-bearing space, and also avoids the pollution of the living environment by foreign objects after long-term use of the airtight pressure-bearing space, thereby improving the air cleanliness of the living environment.

[0046] 5. By expanding the connection skeleton and transforming the connection modules, the space and functions can be expanded in the horizontal and vertical directions. The combined transformer space can form a public corridor. The multi-layer space structure formed by the combination is then connected through the elevator unit module and the stair unit module to form an overall pressure-bearing space.

[0067] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.

[0068] See also Figure 1-3As shown, an embodiment of the present invention provides an assembled pressurized building with a variable space, wherein the assembled pressurized building with a variable space includes at least one variable space unit 1, each variable space unit 1 includes an airtight pressure-bearing space 11 and a combined pressure-changing space 12, both of which are surrounded by an airtight pressure-bearing structure 2 to form a three-dimensional rectangular closed space, and the combined pressure-changing space 12 is assembled and connected to one side of the airtight pressure-bearing space 11 in the width direction;

[0069] The airtight pressure-bearing structure 2 includes a pressure-bearing airtight layer 21 and a fireproof layer 22 and a heat-insulating layer 23 installed inside and outside the pressure-bearing airtight layer 21;

[0070] An airtight pressure-bearing structure 2 shared by the airtight pressure-bearing space 11 and the combined pressure-changing space 12 is also provided with an air intake and exhaust device 3 and a first airtight pressure-bearing door 41. An integrated device system 5 connected to the air intake and exhaust device 3 is also provided on one side of the airtight pressure-bearing space 11. The integrated device system 5 is suitable for controlling and adjusting the environmental parameters inside the airtight pressure-bearing space 11.

[0071] The side of the combined pressure-changing space 12 away from the airtight pressure-bearing space 11 is suitable for installing an airtight pressure-bearing door and window structure or a non-airtight pressure-bearing door and window structure, so that the combined pressure-changing space 12 can perform pressure conversion.

[0072] Specifically in the embodiment of the present invention, the prefabricated pressurized building with variable space is composed of variable space units 1, each variable space unit 1 is composed of an airtight pressure-bearing space 11 and a combined pressure-changing space 12 spliced ​​together, and the airtight pressure-bearing space 11 and the combined pressure-changing space 12 are both three-dimensional rectangular closed space structures surrounded by an airtight pressure-bearing structure 2, and the core of the airtight pressure-bearing structure 2 is the pressure-bearing airtight layer 21, which ensures the strength and airtightness of the structure, and provides fire prevention and heat preservation functions by arranging a fireproof layer 22 and a thermal insulation layer 23 inside and outside the pressure-bearing airtight layer 21, thereby forming an airtight pressure-bearing structure 2 and ensuring the airtightness of the variable space unit 1. The air intake and exhaust device 3 is located on the airtight pressure-bearing space 11 and is connected to the integrated equipment system 5, which is used to control and adjust internal environmental parameters, such as air purification, fresh air intake and exit, etc.; the integrated equipment system 5 can adjust the airtight pressure-bearing space 11 according to the set equivalent altitude, and enter the normal use state after reaching the set pressure, ensuring the stability and comfort of the internal environment; and the first airtight pressure-bearing door 41 is installed on the airtight pressure-bearing structure 2, on the one hand it is used for users to enter and exit, and on the other hand it ensures that the airtightness of the space is maintained when opening and closing.

[0073] Thus, through the structural setting of the variable space unit 1, building components or modules can be prefabricated in the factory, and then assembled and installed on site, realizing a fast, efficient and repeatable construction process. This construction method has the advantages of low construction cost, low design difficulty, good process connection effect, energy saving and environmental protection, and can expand the space according to actual needs; through the adjustment of the integrated equipment system 5, the pressurized building can adapt to different environmental conditions, such as changes in altitude, which enhances the adaptability and practicality of the building and ensures the safety, comfort and flexibility of the variable space.

[0074] For further information, see Figure 1 As shown, the prefabricated pressurized building with variable space also includes an item transfer device 6, which is installed between the airtight pressure-bearing space 11 and the combined pressure-changing space 12. The item transfer device 6 is arranged on the airtight pressure-bearing structure 11 shared by the airtight pressure-bearing space 11 and the combined pressure-changing space 12, and is located on one side of the first airtight pressure-bearing door 41.

[0075] When a non-airtight pressure-bearing door and window structure is installed on the side of the combined pressure-changing space 12 away from the airtight pressure-bearing space 11 , the article transfer device 6 is suitable for transferring articles from the combined pressure-changing space 12 to the airtight pressure-bearing space 11 .

[0076] Specifically in this embodiment, the item transfer device 6 is installed between the airtight pressure-bearing space 11 and the combined pressure-changing space 12. In this embodiment, the item transfer device 6 is arranged on the airtight pressure-bearing structure 2 shared by the two. Considering that the airtight pressure-bearing space 11 needs to have the characteristic of high airtightness, it is necessary to prevent air exchange between different areas to prevent pollution.

[0077] As a preferred mode of this embodiment, the article transfer device 6 is implemented by a mechanical and pneumatic double seal design. For example, a highly elastic pneumatic sealing ring is installed on the inner and outer doors, and then a double-layer sealing belt is formed between the door and the door frame through a clamping mechanism to achieve higher air tightness. The inner and outer doors of the article transfer device adopt an interlocking device. During operation, the double-side doors cannot be opened at the same time to prevent air flow between rooms, which acts as an airlock.

[0078] When a non-airtight pressure-bearing door and window structure is installed on the side of the combined pressure-changing space away from the airtight pressure-bearing space, the design of the article transfer device allows the transfer of articles from the combined pressure-changing space to the airtight pressure-bearing space. This requires that the transfer device be designed to adapt to different pressure environments and maintain airtightness.

[0079] For further information, see Figure 1 As shown, evenly distributed expansion connection skeletons 24 are also provided in the airtight pressure-bearing structure 2 , and adjacent variable space units 1 are spliced ​​horizontally and vertically through the expansion connection skeletons 24 .

[0080] Specifically in this embodiment, the airtight pressure-bearing structure 2 is a key part of the assembled pressurized building, and it needs to have sufficient strength and airtightness to maintain the stability of the internal pressure. The extended connection skeleton 24 is evenly distributed in this structure to play a role in strengthening and connecting.

[0081] Taking into account that the variable space unit 1 needs to be reconfigured and moved according to space requirements, this variable space unit 1 is a core feature of prefabricated buildings. By expanding the connecting skeleton 24, these variable space units 1 can be flexibly spliced ​​horizontally and vertically, thereby realizing rapid adjustment and change of space. The connecting skeleton 24 ensures the stability and airtightness of the structure.

[0082] Thus, the airtight pressure-bearing structure 2 enables the pressurized building space to be quickly adjusted according to usage requirements, thereby improving the adaptability and flexibility of the pressurized building. At the same time, due to the use of modularization and splicing technology, construction efficiency is improved, project cycle is shortened, and resource and energy consumption is reduced.

[0083] Furthermore, a plurality of variable space units 1 are parallel to each other and spliced ​​in parallel along the length direction to form a hall side wall 13 , and the combined variable spaces 12 of the hall side wall 13 are connected to form a public corridor 19 .

[0084] For details in this embodiment, please refer to Figure 2 As shown, multiple variable space units 1 are parallel to each other and spliced ​​in parallel along the length direction to form a first hall side wall 131 and a second hall side wall 132. The first hall side wall 131 and the second hall side wall 132 are mutually enclosed to form a structure with an intermediate hall. For example, the two second hall side walls 132 in this embodiment are vertically connected to the two ends of the first hall side wall 131, forming a hall in the middle.

[0085] At this time, the expansion directions of the first hall side wall 131 and the second hall side wall 132 are perpendicular to each other, and the combined transformer spaces 12 of the first hall side wall 131 are connected to form a first public corridor 191, and the combined transformer spaces 12 of the second hall side wall 132 are connected to form a second public corridor 192, and the ends of the first public corridor 191 and the second public corridor 192 that are close to each other are spliced ​​and connected to connect the first public corridor 191 and the second public corridor 192.

[0086] During the splicing process, since the pressure-bearing building needs to maintain internal air tightness to reduce the equivalent altitude and protect the health of the residents, the air tightness at the splicing nodes is connected by expanding the connection frame 24 to ensure the stability of the internal air pressure of the pressurized building.

[0087] For further information, see Figure 2As shown, the variable space prefabricated pressurized building also includes a staircase unit module 15 and a lobby module 16, wherein:

[0088] The staircase unit module 15 is connected between two adjacent variable space units 1 along the length direction of the variable space unit 1, and a plurality of combined variable pressure spaces 12 are parallelly spliced ​​on both sides of the staircase unit module 15 to form a public corridor 19 on both sides of the staircase unit module 15 and communicate with the staircase unit module 15;

[0089] The lobby module 16 is arranged on one side of the stair unit module 15 close to the variable space unit 1, and the lobby module 16 is connected to the stair unit module 15;

[0090] The variable space unit 1 is suitable for being expanded in the longitudinal direction through the stair unit module 15 to form a multi-layer space structure.

[0091] Specifically in this embodiment, the stair unit module 15 is connected between two adjacent variable space units 1 along the length direction of the variable space unit 1, playing the role of connection and longitudinal expansion, and a plurality of combined pressure-changing spaces 12 are spliced ​​in parallel on both sides of the stair unit module 15, and the combined pressure-changing spaces 12 in each variable space unit 1 are connected in series to form a public corridor 19. In this way, the public corridor 19 can be entered through the stair unit module 15, and then the corresponding airtight pressure-bearing space 11 can be entered through each combined pressure-changing space 12. Therefore, the stair unit module 15 plays a key role in vertical transportation and spatial connection in multi-story pressurized buildings.

[0092] The lobby module 16 is arranged on one side of the stair unit module 15 close to the variable space unit 1 and is connected to the stair unit module 15. Its purpose is to provide a transition space to facilitate the flow and management of personnel, and at the same time serve as the facade of the building to provide circulation and preliminary service functions.

[0093] It is understandable that the variable space unit 1 can be expanded in the longitudinal direction through the stair unit module 15 to form a multi-layer space structure to adapt to different usage requirements and functional changes.

[0094] In addition, by prefabricating the staircase unit module 15 and the lobby module 16 in the factory and then assembling and installing them on site, a fast, efficient and repeatable construction process is achieved. This construction method has the advantages of low construction cost, low design difficulty, good process connection effect, energy saving and environmental protection. Since the staircase unit module 15 and the lobby module 16 have been completed in the factory, on-site assembly and installation can be carried out quickly, which greatly shortens the construction period, and can also realize the recycling of materials and reduce carbon emissions and environmental pollution during the construction process.

[0095] For further information, see Figure 3As shown, the variable space prefabricated pressurized building also includes a conversion connection module 17 and an elevator unit module 18, wherein:

[0096] The conversion connection module 17 is arranged between the combined transformer spaces 12 close to each other on the hall side walls 13 along the longitudinal expansion direction of the variable space unit 1, and the conversion connection module 17 is connected to the public corridor 19; in this way, the conversion connection module 17 can become a key node connecting different spaces and allow the variable space to be expanded and connected in the longitudinal direction. The conversion connection module 17 is also connected to the public corridor 19, which can enhance the spatial fluidity and functionality inside the building and provide a more flexible space conversion and use method.

[0097] The elevator unit module 18 is arranged on the side of the conversion connection module 17 away from the public corridor 19, and the elevator unit module 18 is connected to the conversion connection module 17. The elevator unit module 18 is also connected to the hall side wall 13. This layout allows the elevator unit module 18 to become the core of the vertical connection of the multi-story pressurized building, solving the flow problem of users in the vertical movement of the multi-story space structure.

[0098] The variable space unit 1 is expanded in the longitudinal direction by converting the connection module 17 and the elevator unit module 18 to form the multi-layer space structure.

[0099] Therefore, by converting the settings of the connection module 17 and the elevator unit module 18, the variable space unit 1 can achieve expansion in the longitudinal direction to form a multi-layer space structure. This design improves the spatial flexibility and variability of the building and allows the internal space layout to be adjusted according to needs.

[0100] In addition, since the conversion connection module 17 and the elevator unit module 18 are prefabricated in the factory, they only need to be assembled on site, which can greatly shorten the construction period and improve the construction efficiency.

[0101] For further information, see Figure 3 As shown, the integrated equipment system 5 includes an air boost module 51, a strong and weak current module 52 and an environmental detection module 53;

[0102] The air boosting module 51 is adapted to pump compressed air into the airtight pressure-bearing space 11 to increase the air pressure and oxygen concentration in the airtight pressure-bearing space 11;

[0103] The strong and weak current module 52 is used to provide power and signal transmission to the airtight pressure-bearing space 11;

[0104] The environment detection module 53 is used to detect the environment parameters in the airtight pressure-bearing space 11 in real time.

[0105] Specifically, the main function of the air boosting module 51 is to pump compressed air into the airtight pressure space 11 to increase the air pressure and oxygen concentration in the space. By continuously pumping compressed air, the air boosting module 51 can maintain the air pressure in the airtight pressure space 11 at a suitable level, while the increased oxygen concentration helps to improve the work efficiency and health of people in high-altitude areas. This module is particularly important for maintaining a comfortable environment for people in an airtight space, especially at high altitudes or in a confined environment, where hypoxia can be prevented by increasing the oxygen concentration.

[0106] The strong and weak current module 52 is responsible for providing the necessary power and signal transmission to the airtight pressurized space 11. This module is the key to power supply and communication within the variable space unit 1, ensuring the normal operation of the equipment and the smooth flow of information.

[0107] The environmental detection module 53 is used to detect the environmental parameters in the airtight pressurized space 11 in real time, such as temperature, humidity, concentration of harmful gases, etc. This module collects data through sensors and monitoring equipment to provide decision support for environmental control. Through real-time monitoring of environmental parameters in the airtight pressurized space 11, the environmental detection module 53 can promptly detect environmental changes and take corresponding measures, such as adjusting temperature and humidity, ventilation, etc., to ensure the comfort and safety of the environment in the space. This real-time monitoring and control is particularly important for confined spaces, and can effectively prevent the impact of environmental factors in high altitude areas on personnel health and equipment operation.

[0108] As a preferred mode of this embodiment, the integrated equipment system 5 may further include a water treatment module 54, an energy module 55 and a temperature and humidity adjustment module 56, wherein the water treatment module 54 is used to provide water to the airtight pressure space 11, and to treat the used water to prevent environmental pollution; the energy module 55 includes a power supply, energy management and energy storage system, which is used to convert external energy (such as electricity, heat, etc.) into an energy form suitable for building use, and to manage it effectively, so as to improve energy utilization efficiency, reduce energy consumption and realize sustainable energy utilization through intelligent energy management and scheduling; the temperature and humidity adjustment module 56 is based on the working principle of the temperature and humidity sensor, and measures the temperature and humidity of the surrounding environment, and converts these data into digital signal output for use by other devices or systems to maintain the comfort of the indoor environment.

[0109] For example, the temperature and humidity adjustment module 56 creates a healthy and comfortable living environment by automatically adjusting the indoor temperature and humidity of the airtight pressure-bearing space 11. The temperature and humidity adjustment module 56 in this embodiment includes a detection part and an adjustment display part, which can automatically adjust according to environmental changes to maintain stable temperature and humidity.

[0110] In summary, the integrated equipment system 5 serves as a control center, providing clean water, efficient energy supply and a comfortable indoor environment for the airtight pressurized space 11, thereby improving living comfort and functionality.

[0111] For further information, see Figure 3 As shown, the variable space prefabricated pressurized building also includes a ventilation device 57 and a pressure relief device 58, wherein:

[0112] The ventilation device 57 is arranged on the airtight pressure-bearing structure 2 of the airtight pressure-bearing space 11. The ventilation device 57 is suitable for opening when the airtight pressure-bearing space 11 is in a non-pressurized state, so that the airtight pressure-bearing space 11 is in an air circulation state. The ventilation device 57 generally includes a fan, a filter, a control system and other parts, wherein the fan is responsible for generating power to drive the air flow; the filter is used to purify the air entering the airtight space and remove dust and harmful particles; the control system automatically adjusts the fan speed and operation mode according to indoor and outdoor air quality, temperature and other parameters, and maintains the indoor air quality of the airtight pressure-bearing space 11 by introducing outdoor fresh air and exhausting the polluted air in the airtight pressure-bearing space 11.

[0113] The pressure relief device 58 is installed on the airtight pressure-bearing structure 2 of the airtight pressure-bearing space 11, and the pressure relief device 58 is electrically connected to the integrated equipment system 5. When the pressure in the airtight pressure-bearing space 11 exceeds the design value, the pressure is quickly relieved to protect the building structure of the airtight pressure-bearing space 11 from damage.

[0114] Preferably, the pressure relief device 58 can be a power-free type or a power-powered type. The power-free type relies on a pressure regulating driving component, while the power-powered type is provided with a pressure detection device and an electric driving component.

[0115] Therefore, the ventilation device 57 and the pressure relief device 58 can ensure the air quality and structural safety of the airtight pressurized space 11 under different conditions in the prefabricated pressurized building with variable space, thereby improving the comfort and reliability of the pressurized building.

[0116] For further information, see Figure 3 As shown, the pressure-bearing airtight layer 21 is an important component of the prefabricated pressurized building with variable space. The pressure-bearing airtight layer 21 in this embodiment is formed by welding plates and columns or splicing plates and columns, which can not only ensure the strength and airtightness of the structure to withstand the pressure caused by the internal and external pressure difference, but also maintain the stability of the internal environment.

[0117] When welding is used, the plates and columns are connected by welding to form a continuous airtight pressure-bearing structure 2. During the welding process, the quality of the weld needs to be ensured to ensure that there are no pores and cracks to maintain the integrity and airtightness of the structure.

[0118] When splicing is used, high-strength bolts or special splicing plates can be used. During the splicing process, close contact at the joints must be ensured to ensure the continuity and airtightness of the structure.

[0119] It should be noted that the main function of the pressure-bearing airtight layer 21 is to withstand the internal and external pressure difference and maintain the stability of the structure. Therefore, whether it is welding or splicing, it is necessary to ensure that the structure is not damaged when it is subjected to the design pressure.

[0120] Another embodiment of the present invention further provides a method for using the above-mentioned prefabricated pressurized building with variable space, the method comprising the following steps:

[0121] Step S 100 : Determine the pressure state of the combined variable pressure space 12 in the variable space unit 1 and the state of personnel entering and exiting the airtight pressure space 11.

[0122] In this step, by monitoring the pressure state of the combined variable pressure space 12 in the variable space unit 1 and determining the state of personnel entering and exiting the airtight pressure space 11, it is possible to ensure that personnel enter and exit the airtight pressure space 11 under safe and comfortable pressure conditions. This involves pressure sensors and monitoring systems, which can feedback pressure data in real time so that users can make corresponding adjustments when entering and exiting the airtight pressure space 11.

[0123] Step S 200 When it is necessary to enter the multi-story space structure formed by the combination of variable space units 1, the public corridor formed by the combined variable space 12 can be entered through the stair unit module 15 and the lobby module 16.

[0124] In this step, when it is necessary to enter and exit the multi-story space structure formed by the combination of variable space units 1, the public corridor formed by the combined variable pressure space 12 is entered and exited through the stair unit module 15 and the lobby module 16. In this way, through the spatial layout and modular setting of this pressurized building, users can easily move between spaces on different floors.

[0125] Step S 200 : When the combined pressure-transformation space 12 is in a normal pressure state and the airtight pressure-bearing space 11 is to be used, the normal pressure door of the combined pressure-transformation space 12 is opened to enter the combined pressure-transformation space 12;

[0126] Control and adjust the integrated equipment system 5 to reduce the pressure in the airtight pressure-bearing space 11 to the same level as that in the combined pressure-changing space 12, and close the airtight pressure-bearing door after entering the airtight pressure-bearing space 11;

[0127] The integrated equipment system 5 is controlled and adjusted, and the equivalent altitude is input to increase the pressure of the airtight pressure-bearing space 11. After reaching the set pressure, the space enters the normal use state.

[0128] In this step, the pressure between the airtight pressure-bearing space 11 and the combined pressure-changing space 12 is adjusted by controlling and adjusting the integrated equipment system 5, and the airtight door is opened and closed after ensuring the pressure balance. This process requires precise pressure control and reliable operation of the airtight door to maintain airtightness and safety.

[0129] Among them, when entering the airtight pressure space 11, the airtight pressure space 11 is pressurized by inputting the set equivalent altitude, and enters the normal use state after reaching the set pressure, ensuring that the pressure environment in the space meets specific usage requirements; when leaving the airtight pressure space 11, pressure balance, airtight door operation, etc. are also required to ensure that personnel leave safely while maintaining the airtightness of the space.

[0130] Step S 300 : When the combined pressure-transformation space 12 is in a pressurized state and the airtight pressure-bearing space 11 is to be used, the integrated equipment system 5 is controlled and adjusted to reduce the pressure in the combined pressure-transformation space 12 to the same as that outside, and the second airtight pressure-bearing door 42 on the combined pressure-transformation space 12 is opened, and the second airtight pressure-bearing door 42 is closed after entering the combined pressure-transformation space 12;

[0131] Control and adjust the integrated equipment system 5, increase the pressure in the combined pressure-changing space 12 to the same as the pressure in the airtight pressure-bearing space 11, open the first airtight pressure-bearing door 41 to enter the airtight pressure-bearing space 11, and then close the first airtight pressure-bearing door 41;

[0132] The integrated equipment system 5 is controlled and adjusted, and the equivalent altitude is input to increase the pressure of the airtight pressure-bearing space 11. After reaching the set pressure, the space enters the normal use state.

[0133] In this step, since the combined pressure transformation space 12 is in a pressurized state, when entering the airtight pressure-bearing space 11 for use, the integrated equipment system 5 is first used to adjust and lower the combined pressure transformation space 12 to the same level as the outdoor pressure before entering the combined pressure transformation space 12; and then the integrated equipment system 5 is continued to be used to adjust the pressure balance between the combined pressure transformation space 12 and the airtight pressure-bearing space 11 before entering the airtight pressure-bearing space 11 for use.

[0134] Step S 400 : When leaving the airtight pressure-bearing space 11, control and adjust the integrated equipment system 5, increase the pressure in the combined pressure-changing space 12 to be balanced with the pressure in the airtight pressure-bearing space 11, open the first airtight pressure-bearing door 41 on the airtight pressure-bearing space 11, enter the combined pressure-changing space 12, and close the first airtight pressure-bearing door 41 on the airtight pressure-bearing space 11;

[0135] The integrated equipment system 5 is controlled and adjusted to reduce the pressure in the combined pressure transformation space 12 to the same as that outside, and then the second airtight pressure-bearing door 42 on the combined pressure transformation space 12 is opened, and the combined pressure transformation space 12 is left normally.

[0136] This step introduces the process of leaving the airtight pressure-bearing space 11, which also includes pressure balance, airtight door operation, etc., to ensure that personnel leave safely while maintaining the airtightness of the space. 400 With step S 300 The adjustment process is exactly the opposite.

[0137] In summary, the method of using the prefabricated pressurized building with variable space is to achieve safe, comfortable and convenient entry and exit of personnel in the airtight pressurized space 11 through precise pressure control, airtight door operation and control operation of the integrated equipment system 5, while ensuring the environmental adaptability of the space.

[0138] It should be noted that step S 200 and step S 300 The order can be adjusted as needed, and this method does not impose any restrictions on this.

[0139] 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.
