Description

Technical Field

[0001] This application relates to the field of building technology, specifically to an airtight connector and pressurized chamber suitable for pressurized buildings in cold regions. Background Technology

[0002] Pressurized building complexes in high-altitude and frigid regions effectively alleviate altitude sickness by maintaining indoor air pressure and oxygen content close to that of a plain. Currently, multi-module modular building complexes are mainly used. However, when assembling multiple modules, existing technologies present challenges. While on-site welding at the connection points provides good sealing, it makes later maintenance and replacement difficult. Prefabricated structures require extremely high precision in the machining of the joint surfaces and struggle to guarantee long-term airtightness. The cold external and hot internal environment of high-altitude and frigid regions causes cold bridges at the module joints, leading to condensation of humid internal air upon contact with low-temperature metal, which affects the normal operation of the equipment.

[0003] Therefore, the splicing effect of multi-compartment units in the existing technology is poor. Summary of the Invention

[0041] Please refer to Figures 1-5 In this embodiment of the application, a pressurized chamber is provided, comprising a first chamber unit 12 and a second chamber unit 11, which are connected and sealed by an airtight connector 13. The airtight connector 13 is located inside the first chamber unit 12 and the second chamber unit 11.

[0042] In this embodiment, both the first cabin unit 12 and the second cabin unit 11 include multiple profiles. The multiple profiles of the first cabin unit 12 are all elongated profiles, and these profiles are assembled to form a cuboid cabin unit. Similarly, the multiple profiles of the second cabin unit 11 are also elongated profiles, and these profiles are assembled to form a cuboid cabin unit. The cabin unit has a hollow structure. The first cabin unit 12 includes a first profile 121, and the second cabin unit 11 includes a second profile 111. The first profile 121 and the second profile 111 are arranged opposite to each other. Specifically, the first profile 121 is the profile along the edge of the mating surface of the first cabin unit 12 facing the second cabin unit 11; for example, the first profile 121 is a rectangular frame. The second profile 111 is the profile along the edge of the mating surface of the second cabin unit 11 facing the first cabin unit 12; for example, the second profile 111 is a rectangular frame.

[0043] Among them, the profiles are metal profiles.

[0044] In this embodiment of the application, the airtight connector 13 includes a first fixing part 131, a second fixing part 141, a heat insulation plate 154, a flexible connecting plate, a first pressure block 135, a second pressure block 145, a first fastener 136, and a second fastener 146.

[0045] One side of the first fixing part 131 is used to connect to the first cabin unit 12. Specifically, the first profile 121 is a rectangular frame with a rectangular cross-section and is hollow. One side of the first fixing part 131 is connected to the inner side of the first profile 121. Figure 3 As shown, Figure 3 The cross-section of the first profile 121 is shown, with the upper part of the first profile 121 being the outer side and the lower part of the first profile 121 being the inner side.

[0046] One side of the second fixing part 141 is used to connect to the second cabin unit 11. Specifically, the second profile 111 is a rectangular frame with a rectangular cross-section and is hollow. One side of the second fixing part 141 is connected to the inner side of the second profile 111. Figure 3 As shown, Figure 3 The cross-section of the second profile 111 is shown, with the upper part of the second profile 111 being the outer side and the lower part of the second profile 111 being the inner side.

[0047] The heat insulation plate 154 is located between the first fixing part 131 and the second fixing part 141, with one side of the heat insulation plate 154 facing the gap between the first cabin unit 12 and the second cabin unit 11; the flexible connecting plate includes a first plate segment 151, a second plate segment 152, and a third plate segment 153 arranged in sequence. Figure 3 As shown, one side of the heat insulation plate 154 faces the gap between the first profile 121 and the second profile 111.

[0048] Specifically, the flexible connecting plate is made of rubber.

[0049] The first pressing block 135 and the first fixing part 131 press the first plate segment 151 from both sides. The first fastener 136 connects the first pressing block 135, the first fixing part 131, and the first cabin unit 12. The second pressing block 145 and the second fixing part 141 press the third plate segment 153 from both sides. The second fastener 146 connects the second pressing block 145, the second fixing part 141, and the second cabin unit 11. The second plate segment 152 presses the heat insulation plate 154 from one side to seal the gap between the first cabin unit 12 and the second cabin unit 11. Specifically, both the second fastener 146 and the first fastener 136 are screws. The first fastener 136 passes sequentially through the first profile 121 on the first pressing block 135, the first fixing part 131, and the first cabin unit 12, connecting the first pressing block 135, the first fixing part 131, and the first cabin unit 12.

[0050] The heat insulation plate 154 is installed at the docking point of the two compartment units. When the air pressure inside the compartment is higher than the external atmospheric pressure, the flexible connecting plate is pressed against the inner surface of the heat insulation plate 154. In this way, the internal pressure is borne by the heat insulation plate 154, while the rubber flexible connecting plate is basically not affected by the internal pressure, thus avoiding damage to the flexible connecting plate. Since the flexible connecting plate and the profiles of the first compartment unit 12 and the second compartment unit 11 are separated by the heat insulation plate 154, heat can be effectively insulated, preventing the external gas from directly exchanging heat with the flexible connecting plate.

[0051] Furthermore, the gaps between the heat insulation panel 154 and the cabin unit can be coated with sealant to prevent external gases from directly exchanging heat with the flexible connecting plate through the gaps.

[0052] In this embodiment, the first fixing part 131 has a first groove on the side facing the first pressing block 135, and the first pressing block 135 has a second groove on the side facing the first fixing part 131. The first groove and the second groove are arranged opposite to each other. The airtight connector 13 includes a first pressing strip 134, which is located between the first groove and the second groove. The first pressing block 135 presses the first pressing strip 134, and the first pressing strip 134 presses the flexible connecting plate onto the first fixing part 131. The first pressing strip 134 presses the first segment 151 of the flexible connecting plate onto the first fixing part 131, achieving the first seal. It should be noted that the side of the first pressing block 135 facing the first fixing part 131 may not have a second groove.

[0053] In this embodiment of the application, the first fixing part 131 includes a first base 132 and a first heat insulation part 133. The first groove is located on the first heat insulation part 133. The first heat insulation part 133 is located between the first base 132 and the first pressure block 135. The first fastener 136 passes through the first pressure block 135, the first heat insulation part 133 and the first base 132 in sequence, and is connected to the first cabin unit 12.

[0054] Specifically, the first heat insulation part 133 is a non-metallic heat insulation part. The thermal conductivity of the first heat insulation part 133 is ≤0.2W / m·K. The first heat insulation part 133 can isolate the metal cabin unit from the flexible rubber connecting plate, avoiding direct conduction of heat and cold.

[0055] In this embodiment, the airtight connector 13 includes a first adhesive strip 137. A third groove is provided on the side of the first base 132 facing the first heat insulation part 133, and a fourth groove is provided on the side of the first heat insulation part 133 facing the first base 132. The third and fourth grooves are arranged opposite to each other. The first adhesive strip 137 is located between the third and fourth grooves. The third and fourth grooves compress the first adhesive strip 137 to seal the gap between the first base 132 and the first heat insulation part 133. It should be noted that the fourth groove may not be provided on the side of the first heat insulation part 133 facing the first base 132; the width of the third groove only needs to be wider than the adhesive strip to allow space for deformation of the rubber strip.

[0056] Specifically, the material of the first adhesive strip 137 is rubber.

[0057] In this embodiment, the second fixing part 141 has a fifth groove on the side facing the second pressing block 145, and the second pressing block 145 has a sixth groove on the side facing the second fixing part 141. The fifth and sixth grooves are arranged opposite to each other. The airtight connector 13 includes a second pressing strip 144, which is located between the fifth and sixth grooves. The second pressing block 145 presses the second pressing strip 144, and the second pressing strip 144 presses the third plate segment 153 of the flexible connecting plate onto the second fixing part 141. The second pressing strip 144 presses the flexible connecting plate onto the second fixing part 141, thereby achieving a seal.

[0058] The second fixing part 141 includes a second base 142 and a second heat insulation part 143. A fifth groove is located on the second heat insulation part 143, which is located between the second base 142 and the second pressure block 145. A second fastener 146 passes sequentially through the second pressure block 145, the second heat insulation part 143, and the second base 142, and is connected to the second cabin unit 11. The airtight connector 13 includes a second adhesive strip 147. A seventh groove is provided on the side of the second base 142 facing the second heat insulation part 143, and an eighth groove is provided on the side of the second heat insulation part 143 facing the second base 142. The seventh and eighth grooves are arranged opposite to each other. The airtight connector 13 includes a second adhesive strip 147, which is located between the seventh and eighth grooves. The seventh and eighth grooves compress the second adhesive strip 147 to seal the gap between the second base 142 and the second heat insulation part 143.

[0059] In this embodiment, the pressurized chamber includes a connecting assembly 16. The first chamber unit 12 includes a first profile 121, and the second chamber unit 11 includes a second profile 111. The first profile 121 and the second profile 111 are disposed opposite to each other. A first fixing part 131 is connected to the first profile 121, and a second fixing part 141 is connected to the second profile 111. The first fixing part 131 and the second fixing part 141 are located inside the first chamber unit 12 and the second chamber unit 11. The connecting assembly 16 connects the first profile 121 and the second profile 111 and is located outside the first chamber unit 12 and the second chamber unit 11.

[0060] In this embodiment, the connecting assembly 16 includes a base plate 165, two fastening assemblies 181, and two adjacent corner pieces 161. Each corner piece 161 is a hollow cuboid. The two corner pieces 161 are respectively connected to the first profile 121 and the second profile 111. Each corner piece 161 has a first through hole 162. At least two first limiting blocks 166 protrude from one side of the base plate 165, and each of the at least two first limiting blocks 166 extends into at least two first through holes 162. The fastening assemblies 181 are used to fix the corner pieces 161 to the base plate 165. Specifically, the cross-section of the first limiting block 166 is the same as the cross-section of the first through hole 162. At least two first limiting blocks 166 are respectively embedded in at least two first through holes 162, thereby restricting the horizontal movement of the two corner pieces 161. Alternatively, the cross-section of the first limiting block 166 may be slightly smaller than the cross-section of the first through hole 162.

[0061] Specifically, the first profile 121 and the second profile 111 are pre-recessed with mounting grooves for mounting corner pieces. The two corner pieces 161 are respectively partially embedded into the mounting grooves of the first profile 121 and the second profile 111, and connected to the first profile 121 and the second profile 111. The connection can be made by bolting or welding.

[0062] In this embodiment, the fastening assembly 181 includes a rotating shaft 182 and a second limiting block 183 disposed at one end of the rotating shaft 182. The other end of the rotating shaft 182 is connected to the base plate 165. The second limiting block 183 is elongated, and the first through hole 162 is a strip-shaped hole. When the connecting assembly 16 connects the first cabin unit 12 and the second cabin unit 11, the extending direction of the second limiting block 183 is different from the extending direction of the first through hole 162. The second limiting block 183 is located inside the corner piece 161. Specifically, the second limiting block 183 can be a cuboid, and the first through hole 162 is a rectangular hole. When the extension direction of the second limiting block 183 is the same as the extension direction of the first through hole 162, the second limiting block 183 can pass through the first through hole 162 along the axial direction of the rotating shaft 182 and enter the corner piece 161. When the extension direction of the second limiting block 183 is different from the extension direction of the first through hole 162, the second limiting block 183 cannot pass through the first through hole 162 along the axial direction of the rotating shaft 182, thereby ensuring the connection between the base plate 165 and the corner piece 161.

[0063] In this embodiment, the connecting assembly 16 includes a third fastener 186. A bushing 184 is provided on the other side of the base plate 165. The other end of the rotating shaft 182 passes through the bushing 184. The bushing 184 has two opposing second through holes, and the rotating shaft 182 has a third through hole. The third fastener 186 passes through the second and third through holes to connect the rotating shaft 182 to the base plate 165. Specifically, the third fastener 186 is a bolt. The third fastener 186 passes through the second and third through holes to connect the rotating shaft 182 to the base plate 165, preventing the rotating shaft 182 from rotating. This keeps the extension direction of the second limiting block 183 different from the extension direction of the first through hole 162, preventing the second limiting block 183 from passing through the first through hole 162 along the axial direction of the rotating shaft. This ensures the connection between the base plate 165 and the corner piece 161, achieving locking of the connecting assembly 16 and the corner piece 161.

[0064] In this embodiment, the connecting assembly 16 includes a fourth fastener 187. A fixing plate 185 is provided at the bottom of the bushing 184. The fourth fastener 187 passes through the fixing plate 185 and the base plate 165 to connect the bushing 184 and the base plate 165. The fourth fastener 187 can be a screw. When it is necessary to remove the bushing 184, the fourth fastener 187 can be removed to detach the bushing 184.

[0065] When it is necessary to disconnect the base plate 165 and the corner piece 161, simply remove the fourth fastener 187 and rotate the shaft 182 so that the extension direction of the second limiting block 183 is the same as the extension direction of the first through hole 162. For example, after removing the fourth fastener 187 and rotating the bushing 184 and the rotating shaft 182 as a whole by 90 degrees, the extension direction of the second limiting block 183 is the same as the extension direction of the first through hole 162. The second limiting block 183 can pass through the first through hole 162 along the axis of the shaft and exit the corner piece 161, thereby disconnecting the base plate 165 and the corner piece 161 and unlocking the connecting assembly 16 and the corner piece 161.

[0066] Furthermore, in combination Figure 9 The connecting assembly 16 includes a base plate 165, three (or four) fastening assemblies 181, and three (or four) corner pieces 161 arranged adjacent to each other. The corner pieces 161 are hollow cuboids. The three (or four) corner pieces 161 are respectively connected to three (four) cabin units. The corner pieces 161 are provided with first through holes 162. Three (or four) first limiting blocks 166 are protruding from one side of the base plate 165. The three (or four) first limiting blocks 166 extend into the three (or four) first through holes 162 on the three (or four) corner pieces 161. The fastening assemblies 181 are used to fix the corner pieces 161 to the base plate 165, thereby connecting the three (or four) cabin units.

[0067] This application has the following effects:

[0068] 1. Flexible rubber connecting plates are used for connection. The soft connection sealing method can adapt to the gap and height difference of the docking surface of the cabin unit, which can reduce the requirements for the processing accuracy of the docking surface of the cabin unit and the on-site assembly accuracy. The solution has strong applicability.

[0069] 2. All components (rubber flexible connecting plates, pressure blocks, connectors, etc.) are connected by standardized bolts, and damaged parts can be replaced individually without the need for overall disassembly.

[0070] 3. A non-metallic insulation frame separates the metal cabin unit from the flexible rubber connection plate, preventing direct heat conduction. Sealant fills the gaps in the insulation board, blocking the infiltration of external cold air and completely eliminating conditions for condensation formation.

[0071] 4. The connecting components dynamically match cabin units at different angles through limit blocks, supporting flexible expansion of building complexes.

[0072] The installation principle of the pressurized chamber is as follows:

[0073] The two corner pieces 161 are partially inserted into the mounting grooves at the top of the first profile 121 and the second profile 111, respectively, and connected to the first profile 121 and the second profile 111. Then, the two corner pieces 161 are partially inserted into the mounting grooves at the bottom of the first profile 121 and the second profile 111, respectively, and connected to the first profile 121 and the second profile 111.

[0074] An airtight connector 13 is placed between the first profile 121 and the second profile 111.

[0075] At the top of the first profile 121 and the second profile 111, the cylindrical end of the rotating shaft 182 passes through the first through hole 162 on the base plate 165. The rectangular second limiting block 183 on the rotating shaft 182 is located on one side of the base plate 165, and the other end of the rotating shaft 182 passes through the bushing 184 and is connected to the bushing 184. The fixing plate 185 at the bottom of the bushing 184 is in contact with the base plate 165. Rotating the shaft 182 and bushing 184 causes the extension direction of the second limiting block 183 to be the same as the extension direction of the first through hole 162. At this time, the second limiting block 183 can pass through the first through hole 162 along the axial direction of the shaft 182 and enter the corner piece 161. Rotating the second limiting block 183, for example, by 90 degrees, when the extension direction of the second limiting block 183 is different from the extension direction of the first through hole 162, the fourth fastener 187 is used to pass through the fixing plate 185 and the base plate 165 to connect the bushing 184 and the base plate 165, thereby keeping the extension direction of the second limiting block 183 different from the extension direction of the first through hole 162. The second limiting block 183 cannot pass through the first through hole 162 along the axial direction of the shaft 182, thereby ensuring the connection between the base plate 165 and the corner piece 161.

[0076] At the bottom of the first profile 121 and the second profile 111, only the bottom plate 165 needs to be placed on the bottom of the cabin unit. When the cabin unit is hoisted and positioned, the first through hole 162 passes through the second limiting block 183 on the bottom plate 165. The weight of the cabin unit presses the bottom plate 165 firmly, preventing it from coming out of the first through hole 162. If the bottom of the cabin unit has column legs and its bottom surface does not contact the ground, the connector can be installed as described above.

[0077] Compared to related technologies, the airtight connector includes a first fixing part, a second fixing part, a heat insulation plate, a flexible connecting plate, a first pressure block, a second pressure block, a first fastener, and a second fastener; one side of the first fixing part is used to connect to a first cabin unit, and one side of the second fixing part is used to connect to a second cabin unit; the heat insulation plate is located between the first fixing part and the second fixing part, with one side of the heat insulation plate facing the gap between the first cabin unit and the second cabin unit; the flexible connecting plate includes a first plate segment, a second plate segment, and a third plate segment arranged in sequence; the first pressure block and the first fixing part press the first plate segment from both sides, the first fastener connects the first pressure block, the first fixing part, and the first cabin unit, the second pressure block and the second fixing part press the third plate segment from both sides, the second fastener connects the second pressure block, the second fixing part, and the second cabin unit, and one side of the second plate segment presses the heat insulation plate to seal the gap between the first cabin unit and the second cabin unit. This application uses two sets of pressure blocks and fixing parts to squeeze the edges of the flexible connecting plate from both sides, which can connect and seal two cabin units, thereby improving airtightness. The use of flexible connecting plates for connection and soft connection sealing can adapt to the gap and height difference of the cabin unit mating surfaces, which can reduce the requirements for the processing accuracy of the cabin unit mating surfaces and the on-site assembly accuracy, making the solution highly applicable. The heat insulation plate isolates the cabin unit from the flexible connecting plate, avoiding direct heat conduction and completely eliminating the conditions for condensation formation, thereby improving the splicing effect of multiple cabin units.
